| Message: | 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.
