When I got up to go to the bathroom at 1 a.m. last Monday, my wechat phone rang. It was from Carl, the purchasing manager of Denison hydraulic pump company in the United States. I was very surprised by this phone call. Generally, we communicate with Carl in the form of e-mail and have never used wechat phone. Carl firstly said sorry to disturb my rest, and asked if I could arrange a video conference at 8:00 tomorrow morning. He needs to discuss a troublesome problem with our technical team. I'm concerned that the communication on the phone will not be clear, and asked him to send me a written email first, and then I'll reply to him. Half an hour later, a detailed email with a schematic diagram of the hydraulic system came in. Last week, the hydraulic pump supplied by them encountered problems with his customer. The customer's hydraulic system has been shelved for half a year, and now it needs to be driven. After the operator starts the hydraulic pump, there is no pressure in the hydraulic system. The field engineer judged that there was no flow output of the hydraulic pump, but after inspection, it was found that the rotation direction of the motor was consistent with that of the hydraulic pump, and the oil level, oil temperature and viscosity of the hydraulic pump met the working conditions. The suction system of the hydraulic pump was replaced, including the oil suction pipe and filter. After startup, there was still no flow output. The transmission parts inside the hydraulic pump are intact without falling off, fracture and blade jamming. A week has passed and no reason has been found. Because the hydraulic pump is still in the warranty period, if it cannot be solved in another week, it can only be returned for claim. Carl asked the original supplier of each part for the hydraulic pump and got nothing. After reading the email, I asked him if the hydraulic pump used a hydraulic check valve? Carl said that the hydraulic check valve was provided by HAWE company in the United States, but the after-sales period of the hydraulic check valve has expired. Because AAK supplied hydraulic check valves to their company last year, and the quality was very satisfying, although the hydraulic check valve in this hydraulic pump is not from AAK, he wants to see if AAK technical team can find out the reason. I said there was no problem with the 8:00 video conference tomorrow, because the chief engineer of AAK didn't travel, but I'm not sure if we can help. The next day in the video conference, their engineers showed the whole system. Our chief engineer found that the displacement of the hydraulic pump was 8ml / R, so he asked them to fill the hydraulic pump directly in the oil outlet pipeline, and then start it up. The hydraulic pump still had no flow.
At 05:10 this morning, I was listening to music and browsing emails. Billy, who had no news in 9 months, sent an email. Without reading the email, I could guess that the hydraulic check valve developed by AAK for 3 months last year had a result. Opening Billy's e-mail and it is an annual order of 5,000 hydraulic check valves at one time, with about 500 hydraulic check valves delivered every month. Billy is from a hydraulic equipment company in the United States, he has purchased a small number of high-pressure resistant hydraulic check valves from AAK in the past. At the beginning of last year, his company received complaints from a customer that its high-power bulldozers were prone to weak starting of the hydraulic system after being used in less than half a year. The after-sales engineer found that the hydraulic check valves leaked and can not maintain the pressure and caused the problem. Billy contacted the original manufacturer of the hydraulic check valves, and manufacturer advised that the system pressure of the high-power bulldozer exceeded 450bar, and the opening and closing frequency was also high. When the hydraulic check valve was in the high-pressure state above 450bar, the valve spool was worn quickly, and the service life could only be guaranteed as 1 million times. Therefore, it was normal to replace the hydraulic check valves every half a year. If you want a hydraulic check valve with a service life of 2 million times, you can only purchase it from German HAWE. Billy has no choice but to make do with the hydraulic check valves of the original manufacturer first, but the after-sales cost every half a year is really unbearable. Maybe other manufacturers can offer hydraulic check valves with service life more than 1 million times. Billy began to contact other factories, including AAK. After receiving Billy's email, AAK engineers had reached a conclusion according to the hydraulic check valve drawings and bulldozer working parameters. In order to exceed the service life of 2 million times of the hydraulic check valves, we can only test new high-pressure resistant materials. We replied Billy at that time that according to the existing steel options of AAK, what your original manufacturer said was right, it can only guarantee the service life of 1 million times of the hydraulic check valves. However, we are confident to develop the one of 2 million times, because we have our own R & D experience in anti-high pressure. Billy replied directly that AAK would be given 3 months to sample the hydraulic check valves with pressure resistance above 450 bar. He also frankly informed that two other hydraulic check valve manufacturers were also making samples. If all manufacturers fail, they can only buy high-pressure hydraulic check valves from German HAWE. Three months later, AAK successfully sent 20 hydraulic check valve samples to Billy. Nine months later, the email came from Billy today.
