| Message: | Dolly is from a hydraulic equipment company in Peru. His boss thinks highly of him and plans to promote him to be purchasing manager, but a hydraulic cartridge relief valve stumped him. In the first half of last year, they sold a batch of hydraulic power units. 3 months later, the customer complained that the adjusting screw of the hydraulic cartridge relief valve had serious slippage, and the failure to adjust led to the strike of the equipment. The hydraulic cartridge relief valve manufacturer advised that this hydraulic cartridge relief valve benchmarks HydraForce, and the material is the same as HydraForce. The adjusting screw slipped after 3 months, which was caused by the high frequency of use. It can only be replaced with new ones. But it still slipped after 3 months. The customer was not satisfied, and the boss was also angry. He asked Dolly to replace the manufacturer of the hydraulic cartridge relief valve with a new one and ensure that it was safe for 1 year. Dolly became to be under great pressure. |
