Achilleus is from Greece. In the second half of last year, a high-pressure hydraulic winch sold by his company for less than 3 months, was unable to rise and fell suddenly during construction, which almost caused a safety accident. The on-site investigation found that an oil pipe in the hydraulic system was broken and leaked oil. After the oil pipe was replaced, the equipment was restored. But 2 months later, similar problems repeated. The customer couldn't stand this series of problems and complained to the boss. The boss was angry and asked the technical team to solve it completely within 1 month. Achilleus also felt the pressure of the boss and contacted several factories to inquire, but there was no result.
Achilleus saw AAK on Google and sent an email asking with a try attitude, and attached the hydraulic schematic diagram. After analysis, AAK engineers found that the probable reason was that the oil pipe burst was caused by the energy conflict between the hydraulic counterbalance valves in the system and the flow control of the system. We informed Achilleus of the analysis results the next day and recommended that AAK make the samples directly. We will redesign the hydraulic counterbalance valve according to the energy principle of the hydraulic system. 3 days later, Achilleus placed the sample order for 10 hydraulic counterbalance valves and also paid the development cost. After 45 days, AAK sent the samples.
Last week, Achilleus sent an email to express his thanks. After using the hydraulic counterbalance valves redesigned by AAK, the hydraulic winch has been running stably for half a year, and the customer is also very satisfied. The boss praised him, too. Their engineers admire the design ability of AAK and suggest Achilleus to take AAK as the preferred supplier of hydraulic counterbalance valves.
AAK unique designed hydraulic counterbalance valves, with triple safety protection, customers no longer worry about the burst of the oil pipeline of the hydraulic system.
1. AAK changed the flow control groove of the hydraulic counterbalance valve, and redesigned small flow control groove. The maximum working pressure can reach 420bar, realizing zero leakage load maintenance. Even if the oil pipeline bursts, the load will not be out of control.
2. The working mode of the hydraulic counterbalance valve designed by AAK is similar to a two position flow controller with compensation, which can realize the curve of different forms of flow decreasing with the increase of load pressure, so that the control tank with small flow can realize the optimization of control.
3. According to the characteristics of this winch hydraulic system, the hydraulic counterbalance valve designed by AAK has different damping combination configurations, so as to ensure the stability of the winch hydraulic system.
