However, a more closed system, open and complex systems, because no fuel tank, oil cooling and filtering the disadvantaged.
但闭式系统较开式系统复杂，因无油箱，油液的散热和过滤条件较差。
Meanwhile, using a filtering device to recycle the system oil to keep it clean is also available.
同时，也可用滤油设备对整个液压系统进行循环过滤，净化液压系统的油液。
These system include filtering system for crude oil entering, filtering and cooling system for hot oil, filtering and cooling water circulating system for reduction gearbox of the drilling motor.
该系统包括原油入口的过滤装置，热油过滤冷却装置和钻井马达变速箱过滤冷却循环装置等三大部分。
