Hydraulic Manifold Block Processing

Only AAK was able to produce the hydraulic manifold blocks, and its technology is not inferior to American and Japanese counterparts Scott comes from an equipment company in the United States. In the second half of last year, they developed a hydraulic equipment to be introduced at the exhibition. The chief engineer of the company requires the purchasing department to get all hydraulic manifold blocks arrive at the factory within 3 months. There is a hydraulic manifold block. Due to the slow production, the production time of 45 days is not enough. Scott disassembled the hydraulic manifold blocks, purchased the hydraulic valve blocks from one factory and the hydraulic cartridge valves from another factory. All hydraulic manifold blocks and those parts produced separately arrived at the factory in the United States in 3 months. The technicians in the workshop installed them. After a few days of commissioning, they found that there were oil leakage on one hydraulic manifold block, that is the one disassembled and produced in two different factories. The chief engineer requires getting a new hydraulic manifold block within 1 month, otherwise it will be too late to catch the exhibition. Scott contacted the original manufacturer. As a result, the two hydraulic valve manufacturers prevaricated each other. Their engineers also tested the hydraulic cartridge valves and hydraulic valve blocks separately, and there was no abnormality. Scott tried to contact new manufacturers of hydraulic manifold blocks, but they all said that they couldn't get samples ready within 30 days. Scott was worried. Scott saw on AAK website that a hydraulic manifold block was very close to the size he wanted to purchase, so he sent an inquiry. After two rounds of communication, we learned about the problems he encountered in purchasing hydraulic manifold blocks. I told him that if the hydraulic cartridge valves and the hydraulic valve blocks were approved to be no problem, the workshop technician might break the seal ring or shift the seal ring during the installation of the hydraulic manifold blocks. This kind of hydraulic manifold blocks purchased from different manufacturers and then assembled is easy to have problem. A customer of AAK encountered similar problems before. After Scott asked their mechanic to replace the sealing ring, there was no abnormality in the test run, and they could catch up with the exhibition. Scott is glad that the problem of hydraulic manifold block has been solved, and said that for all hydraulic equipment orders after the exhibition, the hydraulic manifold blocks will be purchased from AAK, and also asked us to send hydraulic manifold blocks with similar dimensions to the United States to test stability and service life.

With hydraulic manifolds, the energy consumption of the original unsalable equipment not only decreased by 20%, but also became hot seller is from a agricultural machinery equipment company, mainly responsible for purchasing hydraulic components. In the second half of last year, the sales of one of their rotary tillers were poor. Users reported that the equipment was insensitive and inefficient, and the fuel consumption was 10% higher than that of the same type of equipment. The boss realized that there were hidden dangers in the hydraulic manifolds and asked the engineers to check the causes. However, more than 1 month had passed and there was no practicable plan. The boss was worried and asked to contact the original hydraulic manifold manufacturer to see if they could provide technical support, but they were only good at producing hydraulic manifolds according to the drawings. Connor also asked all his manufacturers of hydraulic components, but none of them gave a plan. When reported these to his boss, he could only helplessly look at his boss shaking his head. the display and introduction of hydraulic manifolds, and left a message: what is the relationship between hydraulic equipment with high energy consumption and slow response and hydraulic manifolds I understood that Connor had a problem with hydraulic manifolds, but it was difficult to answer. After several communications, I learned that his boss was worried, and wanted to solve the problem that had plagued his company for nearly 3 months. According to the hydraulic manifold drawings and the video of rotary tiller work sent by engineers had discussion. The probability was that the hydraulic manifold design had hidden problems. From the analysis of hydraulic manifold and system schematic diagram, there were certain energy conflicts between the design of some oil circuits and the selection of hydraulic valves. could redesign the hydraulic manifold to match their equipment. also readily paid the development cost. 1 month later, sent the hydraulic manifold samples. 2 months later, said that after their rotary tiller was installed with hydraulic manifolds, it was responsive during operation. The operation was more than 20% higher than before, and the fuel consumption was also reduced by 20%. The customer feedback was good, and more and more customers came to try it out. told me privately that he had seen his boss's long lost smile. The boss paid more and more attention to him. He will be promoted to the management next month. hydraulic manifold has 3 advantages 1. engineers have experience in hydraulic manifold design, especially in oil circuit design. Ensure flow distribution as required, eliminate bypass throttling loss and reduce energy loss.

Increase the equipment efficiency by 11% and reduce the energy consumption by 30%. AAK exclusive hydraulic manifold has no rival At the beginning of March this year, Bartolomeo said in an email that he would like to make an appointment to consult AAK about hydraulic manifold problems. Bartolomeo, from Italy, is the purchasing manager of Italpresse Industrie Shanghai Branch. According to the communication, their company developed a hydraulic die-casting machine at the end of last year. The sales volume is just so. The general feedback is that the equipment has high energy consumption and low production efficiency. Their engineers pondered for more than 2 months, but couldn't find the reason, and the boss also had a big headache. Bartolomeo felt that the hydraulic manifold design dragged down the equipment and consulted the original hydraulic manifold manufacturer. However, the manufacturer could not put forward constructive opinions on the hydraulic manifold design. Bartolomeo thought of AAK, because AAK had proposed to modify the oil circuit when receiving the inquiry about the hydraulic manifold. According to the design drawings and system schematic diagram of hydraulic manifold provided by Bartolomeo, AAK engineers closed the door and discussed for 3 days, basically found out the direction, and it is 90% determined that there was a deviation in the oil circuit design of the original hydraulic manifold on the hydraulic die casting machine. There is an energy conflict between the original hydraulic manifold oil circuit aperture and the hydraulic valve used, resulting in the slow response of the hydraulic system and the need for additional energy to maintain the operation of the system, resulting in high energy consumption and low production efficiency. AAK can redesign the hydraulic manifold oil circuit and send hydraulic manifold samples within 30 days. Bartolomeo was very happy that AAK found the cause of hydraulic manifold problem at once. The situation was fed back to the boss, who immediately paid for AAK to redesign and test samples. A month later, AAK sent out the whole newly designed hydraulic manifold. Two weeks later, Bartolomeo emailed to order 20 hydraulic manifolds first to replace those ones on the equipment complained by customers. I was surprised that there was no comment on AAK hydraulic manifold samples but received the urgent order first. Bartolomeo advised that according to the comparison of their engineerâ??s on-site test run, the die casting machine with AAK hydraulic manifold has a sensitive response, the working efficiency is 11% higher than before, whatâ??s more, the energy consumption is reduced by 30%. Their boss asked to order some hydraulic manifolds for emergency use first, and then replace all hydraulic manifolds on the original equipment with AAK shipments.

Cement block hydraulic press. The quality of the cement block machine is important, but the most important question after the purchase of the cement block machine is the maintenance and how to use it correctly. Although the cement block machine is a good device, it can't play its role without proper method. First turn on the cement block machine installed in a horizontal concrete above, and then fixed die, and then to carry on the correct installation, and insist on whether firm, according to the cement block machine equipment control switch, and then to carry on the test, the end can be normal production.

The hydraulic valve blocks designed and produced by not only has high reliability and small pressure loss to ensure that there is no oil running between the channels, but also has compact structure, small occupied space, simple oil circuit and easy pipe layout, so as to ensure the high efficiency requirements of different actions of various actuator elements. The valve block can control the valve, which is easy to adjust and operate. hydraulic valve block was designed and proofed successfully at one time within 1 month, which impressed the engineers o The vast majority of hydraulic valve block manufacturers blindly proofed according to customer drawings, ignored working conditions, and did not understand the internal structure and working principle of hydraulic valve block. It is easy to cause hidden dangers in the hydraulic system, and the problem cannot be found. power insensitivity of the hydraulic system related to the hydraulic valve block We replied that this is difficult to judge because it is a system problem that needs to be checked one by one. the next day then we understood why he left such The power unit of a hydraulic system developed by his company needs a hydraulic valve block. Their engineers mentioned that the sensitivity of the power unit is the key and that all components need to cooperate closely. the hydraulic valve block manufacturer strictly controlled the accuracy according to the drawings, it could be easily done. After the hydraulic valve block is finished, it is installed to test the hydraulic power unit. After the oil pump is started, the instantaneous pressure supply at the oil outlet of the power unit does not come up, and it just supply normal pressure after a few minutes. After checking each component one by one, it is suspected that there are hidden dangers in the hydraulic valve block. After detecting the hydraulic valve block, there is no problem in the oil passage and channel of the hydraulic valve block the original hydraulic valve block manufacturer for analysis and solution. The manufacturer said that the hydraulic valve block was completely produced in accordance with the drawings and the accuracy was within the required range, and the reason for problem was unknown. hydraulic valve block , they all said that they could match the drawings, but not sure about the problems of the hydraulic valve blocks. hydraulic system and the picture of the oil circuit running direction of the hydraulic valve blocks of the original have ideas after 3 aspects of comparative analysis.

This morning, Joselito sent an email asking about the production time of 1,000 hydraulic manifold blocks, which surprised me a little, because in the past two years, Joselito has basically placed orders for just hydraulic valves only, but very few for the hydraulic manifold blocks. Joselito is a purchaser of BEZARES company in Spain. We met 2 years ago. After communication, it was learned that he encountered problem on the hydraulic manifold blocks purchased this time. A batch of hydraulic winch equipment of their company was complained by some users that the winch was often weak. Their after sales found that the hydraulic manifold block was leaking. Because of the purchase cost limitation, he disassembled the hydraulic manifold blocks and purchased them separately from 3 hydraulic valve manufacturers. Now the leakage problem of the hydraulic manifold blocks has come, all 3 manufactures prevaricate and are not responsible for the oil leakage of the hydraulic manifold blocks, they thought that the problem was caused by the unreasonable design or the wrong installation method of the hydraulic manifold blocks. The engineer checked the hydraulic manifold blocks one by one and found different problems, some sealing ring was broken, some gasket at the interface was worn, and some has iron filings in the valve hole. In the past year, a lot of money, labor and maintenance costs were spent on the after-sales for the hydraulic manifold blocks. Now the customers are not satisfied with their after-sales performance, and the boss is not happy to spend the after-sales money indiscriminately. Joselito has a big headache. AAK suggests that Joselito should purchase the whole hydraulic manifold blocks in one factory as much as possible, because each hydraulic valve manufacturer has different quality positioning. AAK has now received more and more inquiries for hydraulic manifold blocks, including Skyjack, a Canadian listed company, and Brevini, a top company in the field of transmission. Joselito finalized the purchase contract of the hydraulic manifold blocks with AAK in two rounds, and required that AAK hydraulic manifold blocks should not be reported for repair within 1 year. It is not only the hydraulic valves and hydraulic manifold blocks produced by AAK with quality assurance, but also 3 points that are difficult for peers to do well: 1. AAK shall deeply clean the hydraulic manifold blocks before assembly to ensure that it is 100% free of iron filings, dirt and other impurities. 2. Only technicians with more than 10 years of experience are qualified to assemble, check the matching between the duct and the hydraulic schematic diagram, and test the accuracy of each duct to ensure that the sealing ring of the hydraulic valves will not be damaged. After assembly, use the test bench to debug the hydraulic manifold blocks for many times, including pressure test and function test,

Hydraulic valve blocks with no deviation in valve hole accuracy, AAK replaced Russian manufacturer Sumarokov comes from Russia and has been engaged in the procurement of hydraulic valve blocks for 7 years. His boss also thinks highly of him. At the beginning of the year, Sumarokov needed to purchase a hydraulic valve block for use in a hydraulic tractor. He took samples from local hydraulic valve block manufacturers, and the test run was smooth. But he didn't expect that 1 month after the sale of the hydraulic tractors, some customers complained that the equipment was unstable and there was leakage at the hydraulic valve block aperture, but the original hydraulic valve block manufacturer thought that it had nothing to do with their hydraulic valve blocks. There were more and more complaints from customers, but the original manufacturer did not cooperate, and Sumarokov had a big headache. On B2B, Sumarokov saw many articles about hydraulic valve blocks from AAK and left us a message: can you ensure that every valve hole of hydraulic valve blocks is processed without deviation? I guessed that the machining accuracy of the holes of the hydraulic valve blocks he purchased was uneven. After communication, I learned that he was in trouble. I told him that most hydraulic valve block manufacturers use 5 processes of drilling, reaming, spot facing, reaming and grinding to process the valve holes. The hidden trouble is that in the process of hole reaming and grinding, the expansion of the orifice is not easy to control, and the aperture may not be absolutely consistent. I suggested Sumarokov directly trying AAK samples of the hydraulic valve blocks. Whether AAK can do it well or not, it does not depend by mouth. You can tell by the samples directly. Sumarokov accepted my proposal and paid for the development cost. After 25 days, 40 hydraulic valve blocks were sent out to solve the customer's complaint first. Last week, Sumarokov said in an email that it has been 3 months since AAK hydraulic valve block was installed on the hydraulic tractor, and there is no complaint of leakage. The hydraulic valve block looks simple, but in the processing of valve holes, the processing technology needs to be determined according to different accuracy requirements, not simple drilling, reaming, spot facing, reaming and grinding. AAK is different and lead most hydraulic valve block manufacturers with 3 points. 1. Choose the reamer. For the processing of the valve hole of this hydraulic valve block, we use the reamer made of 50W6MO5G4V2A1 material with hardness of HRC66 instead of the conventional W18Cr4V. 2. In terms of equipment, we use a high-precision machining center imported from Switzerland. The roughness of the processed hydraulic valve block valve hole can reach Ra value of 0.8-0.4�¼m. The ovality circle error and taper error can be controlled within 0.01-0.02mm, and the valve hole size accuracy can be controlled within 0.01mm.
