| Message: | Friedlich, from Wirth company in Germany, sold the drawworks of oil drilling rigs to the Middle East at the beginning of last year. Six months later, the customer complained that the disc brake controlled by the hydraulic cylinder of the drawworks was weak, resulting in equipment shutdown. The reason was that the hydraulic flow control valve in the hydraulic system was stuck. Friedlich wondered that the same batch of drilling rigs and drawworks had been sold to Canada, Central Europe and other markets for almost 1 year, and there was no such abnormality. The original manufacturer of the hydraulic flow control valves is not sure why it is stuck for half a year, but is willing to offer 30 hydraulic flow control valves for replacement and send them to the Middle East. Friedlich was very worried about such solution without knowing the cause of the stuck valve spool. Sure enough, a batch of hydraulic flow control valves had to be replaced 6 months later. This frequent after-sales service not only costs a lot, but also makes the customer dissatisfied. The boss asked Friedlich to purchase new hydraulic flow control valves with high temperature resistance and durability of more than 1 year as soon as possible to replace the current ones.
