Andrew is the purchasing director of VIS Hydraulics in Italy and an old friend of AAK. He has cooperated with AAK for more than 4 years. One morning in October, I received an email from Andrew with the subject of "a big trouble". It is the first time that I received such an emotional email from Andrew. After reading, it turned out that the pressure of a hydraulic power system of their company was not enough, and the customer complained. The root of the problem is that the hydraulic threaded cartridge valve and hydraulic valve block does not match each other. The owner asked him to solve the problem within a month.
After communication, it was learned that the hydraulic threaded cartridge valve and the hydraulic valve block purchased by Andrew were not produced by the same manufacturer. Now both manufacturers do not admit that it was their own problem. The hydraulic threaded cartridge valve manufacturer said that the pressure of the hydraulic system was slow due to the processing accuracy of the hydraulic valve block, while the hydraulic valve block manufacturer said that the hydraulic threaded cartridge valve had leakage, resulting in insufficient flow. Andrew failed to communicate for several times and thought of AAK. During so many years of cooperation, only AAK hydraulic valve has no complaint. He hopes that AAK can help him find out what the problem is.
Andrew sent us the design drawings of the hydraulic threaded cartridge valve and hydraulic valve block. After analysis, AAK engineers found that the probability is that the design of the hydraulic valve block is unreasonable, the flow area of the through hole designed is not enough, and the direction and position of the oil inlet and outlet are not optimal, resulting in insufficient pressure of the whole hydraulic system. Andrew asked the hydraulic valve block manufacturer to design and produce, but the manufacturer needs 2 months to complete it, while the time given by his owner is only 1 month. Andrew asked the fastest time that AAK can finish the hydraulic valve block.
Our engineers are worried that there may be deviation if design the hydraulic valve block alone. If combined with the mapping of the valve, we can achieve 100% of the optimal design scheme. We recommended Andrew to send us the hydraulic threaded cartridge valve, too. After receiving it, the scanning analysis was carried out, and the design scheme was obtained 2 days later. After 20 days, the redesigned hydraulic valve block was sent to Andrew. After installation and commissioning, the pressure of the hydraulic system was normal. After the complaint was resolved, the owner was also happy and asked Andrew to purchase both the hydraulic threaded cartridge valve and hydraulic valve block from AAK in the future. Don't purchase them separately any more.

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.
Recently, I received the second re-order of a hydraulic pressure reducing valve from French client Chinning. I still remember when I first met Chinning in 2020, Chinning purchased hydraulic pressure reducing valves in a hydraulic valve factory and encountered quality complaints from her customers. The hydraulic pressure reducing valve was deformed in less than 3 months, and some valve spools and valve sleeves were seriously worn. More and more customers began to return goods, and the old suppliers did not cooperate with her work. Chinning had a big headache at that time, and the owner kept putting pressure on her to find a hydraulic valve manufacturer with exquisite quality as soon as possible. Chinning did not find a new hydraulic valve manufacturer very smoothly. Because her hydraulic pressure reducing valve had a special use scenario and required high hardness of materials, it was unbearable for ordinary factories. At the same time, under the environmental protection policy of 2019, many previous heat treatment and processing factories were shut down, so the supply supporting system was disrupted, and the heat treatment and processing of many hydraulic valve manufacturers could not keep up. how does AAK ensure the service life of hydraulic valve products We didn't answer directly, but asked her if the hydraulic valves you purchased had the problem of deformation and rapid wear. She also replied quite frankly that she should find a hydraulic valve manufacturer that paid attention to the service life of hydraulic valves in the fastest time. I sent her several samples of hydraulic pressure reducing valve and told her that different parts of our hydraulic pressure reducing valve have different material hardness standards, and some could reach about 50-55HRC or higher. There is even no problem with 65HCR with special requirements. The service life of hydraulic pressure reducing valve is our hard index. More than one week after we sent out the samples of hydraulic pressure reducing valve, we received Chinning's email, including the drawings of hydraulic pressure reducing valve and the hardness requirements for various components. She asked whether we could produce this hydraulic pressure reducing valve? I told her that his hydraulic pressure reducing valve is not difficult, but just the working scene is some special. As long as the heat treatment process is a little unique, it could ensure her requirements. The long service life of hydraulic valve is the most critical.
For the Hydraulic Manifold Block with porous system like cranial nerve, after made samples successfully, They have a special hydraulic manifold block, which includes 13 groups of M32 threaded holes, and all of them are stepped holes. At the same time, there are cross holes, straight holes, and bypass holes. The hole size is required to be more than 8. Compared with the hydraulic manifold blocks with 10 groups of normal threaded straight holes, it is not only complex in structure, but also 20% higher in precision. Arno knew that it was difficult, so he arranged 3 hydraulic manifold block manufacturers for proofing, which lasted 60 days, but all of them failed to meet the standard. This is a test order of hydraulic manifold block from an old customer. Arno wants to struggle again. Due to time constraints, he does not dare to use a new hydraulic manifold block manufacturer. His old hydraulic manifold block supplier is also unreliable. This makes , who has eight years of procurement experience, a little overwhelmed. I had a hunch that this hydraulic manifold block was not simple. Because the PO of hydraulic manifold blocks given to me by is a challenge every time. engineers pondered over the drawing of hydraulic manifold block sent by , and it is really difficult to process, with very high precision. There are not only many pore systems, but also many deep holes, more than 20 groups of 4 deep holes, with a length diameter ratio greater than 25. For M32 threaded holes of stepped holes, the coaxiality between holes is required to be 0.02mm, and the coaxiality between threads and holes is required to be 0.045mm. This complex pore system structure is like the distribution of the nervous system of the human brain. Doctors without more than 10 years of experience in brain surgery may not be confident to operate on the operating table. technical team, after 3 days of internal research and discussion, the plan has been worked out, and our chief engineer will handle the knife, starting from the production drawing of the hydraulic manifold block. However, I replied to that was only 90% sure that the sample of this hydraulic manifold block was successful, and the cost was not low. Maybe hesitated and didn't give any reply for 3 days. On the fifth day, received the development fee paid by him.
Fasteners are the general term of the class of mechanical parts used in fastening two or more parts (or components) into a whole. It is widely used in energy, electronics, electrical appliances, machinery, chemical, metallurgy, mold, hydraulic and other industries, at the same time, in various kinds of machinery, equipment, vehicles, ships, railway, bridge, construction, structure, tools, instruments, chemical, instruments and supplies, you can see all kinds of fasteners, is the most widely used mechanical foundation parts. It is characterized by a wide variety of variety specifications, different performance uses, and a very high degree of standardization, series, and generalization. Therefore, a class of fasteners that already have national standards is called standard fasteners, or simply standard ones.
hydraulic relief valves . purchased a batch of hydraulic relief valves for crane system in because the original supplier was not able to meet the delivery. He sent an email last week saying with hydraulic relief valves, the stability is 8% higher than that of the original supplier, and there is almost no external leakage. This surprised him. The use experience of hydraulic relief valves has benchmarked with their previous local hydraulic relief valve manufacturers The vast majority of hydraulic valve bodies are made of nodular iron, vermicular iron and gray iron and cast with resin sand as the molding medium. Therefore, there is sticky sand in the casting, which is easy to pollute the oil system and block the valve and filter, which is the key factor affecting the stability of hydraulic relief valves. Most of the common sand cleaning methods of hydraulic relief valves used in the industry are shot blasting and electrochemical sand cleaning, all of which have limitations. 1. Shot blasting can not completely remove the sticking sand from the valve hole with complex structure and small oil passage, which is easy to affect the tightness and product accuracy, and is not conducive to the stability of the hydraulic relief valves. 2. Electrochemical sand cleaning can relatively remove the sticky sand in the narrow oil passage, but it has high energy consumption, high operation intensity of workers, easy to have human errors, can not completely remove the sticky sand, and is not conducive to the stability of the hydraulic relief valves. Improving the quality of hydraulic parts processing process, improving the cleanliness level and ensuring the stability of hydraulic relief valves has always been the hard index of hydraulic relief valves. Auxiliary processing of hydraulic parts mainly includes: sand cleaning of valve body, deburring or residue treatment of parts and cleaning of hydraulic parts. How does do the sand cleaning of hydraulic relief valves technical team has continuously improved the sand cleaning process of hydraulic relief valves after years of technical improvement. For the sand cleaning of small complex castings, has its own unique sand cleaning 5 methods, namely: artificial aging - Pickling - rinsing - rust prevention - ultrasonic cleaning. Artificial aging is used to reduce the binding force between the casting and sand, acid pickling is used to remove the oxide skin at the joint between the sand and the casting to peel the sand from the casting, and then the explosion of compressed air during ultrasonic cleaning is used to peel off the sand, so as to achieve the purpose of sand cleaning. has its own unique advantages of sand cleaning 5 methods: (1) it is less affected by the casting structure; (2) it is
