(1)深井泵在工作中受砂、蜡、水、气及稠油的影响，工作条件恶劣导致了泵的损坏。由于油井出砂，使活塞与衬套磨损严重，活塞端面和防砂槽镀铬脱落，衬套成椭圆形。

(1) Deep well pumps are affected by sand, wax, water, gas and heavy oil in their work. The poor working conditions lead to the damage of the pumps. Because of sand production in oil wells, piston and bushing are worn seriously. Chromium plating on piston end face and sand control tank falls off, and bushing is elliptical.

(2)带泵筒酸化，造成衬套和固定阀腐蚀。

(2) Acidification with pump barrel causes corrosion of bushing and fixed valve.

(3)部分斜井造成活塞与衬套偏磨。推荐阅读：无负压供水设备的原理

(3) Partial inclined wells cause eccentric wear of piston and bushing. Recommended Reading: Principle of Non-negative Pressure Water Supply Equipment

(4)由于地层水、硫化氢气体腐蚀，使阀球、阀座、活塞和衬套损坏。

(4) The ball, seat, piston and bushing are damaged due to formation water and hydrogen sulfide corrosion.

(5)由于打捞、碰泵、对扣时不严格按照操作规程进行，造成固定阀锁环断裂，打捞头撞断、弯曲等现象。搬运中不注意轻搬轻放，造成深井泵外管弯曲或碰扁。专注于水泵和供水系统的研发，主要的产品有潜水泵，地面泵，污水泵，消防泵和供水系统，提供一整套的关于工程的解决方案，快速便捷的满足需求。广泛应用于电厂、钢厂、矿山、油气、市政和自来水厂、温泉、喷泉、工业应用、建设和农业市场。面向未来，尤孚将不断开发更加节能、和性价比更高的水泵和泵系统产品，致力于成长为更加专业化、化的国际流体设备供应商。

(5) Because fishing, bumping and buckling are not strictly carried out in accordance with the operating rules, the locking ring of the fixed valve is broken, and the fishing head is broken and bent. When handling, the outer pipe of deep well pump is bent or rubbed flat due to neglect of light handling and light handling.
