白钢阀块用于电液伺服控制系统

，在TRT装置中

，属于八大系统之一的分系统。

阀块的失效主要体现有孔和杆之间配合间隙过大、动态密封磨损、控制台肩磨损、阅的气蚀等。大连精密零部件加工厂家归纳出形式有以下三点：

（1）性能退化：约占失效的15%；

（2）性能下降：约占失效的70%

，分为腐化和机械磨损

，机械磨损又可细分为磨损、老化、粘合损坏；

（3）意外事故：约占失效的15%。

泛起阀块失效最主要的两大原因是：

（1）油液的清洁度不敷；

（2）系统进入空气。

The white steel valve block is used in the electro-hydraulic servo control system and is a subsystem of one of the eight major systems in the TRT device.

The main manifestations of valve block failure include excessive clearance between the hole and the rod, dynamic seal wear, console shoulder wear, and cavitation. Dalian precision parts processing manufacturers have summarized the following three forms:

(1) Performance degradation: accounting for approximately 15% of failures;

(2) Performance degradation: accounting for about 70% of failures, it is divided into corrosion and mechanical wear, and mechanical wear can be further divided into wear, aging, and adhesive damage;

(3) Accidents: accounting for approximately 15% of failures.

The two main reasons for valve block failure are:

(1) The cleanliness of the oil is insufficient;

(2) The system enters the air.
