Top Tips on How to Maintain Gear Pump

Gear pump is one of popular pumps in the current, which is widely applied to a lot of industrial fields. Comparatively speaking, it enjoys much easier structure that consists of two same size toothed gears, front and behind shields and pump body. The simple structure paves the way for understandable working principle. An enclosed space is made up the mentioned four parts. When two toothed gears begin rotating, such an enclosed space is becoming bigger increasing. At the same time, the liquid substances will come into that enclosed chamber. When the chamber reaches the biggest volume, it will start to shrink until the liquid is squeezed into pipeline totally.

There are several different types of high quality pumps in the nowadays market like multiple gear pumps, PTO gear pumps and the like. What are they used for? Get to know the basic function of gear pump in the very first place. All of the gear pumps are mainly used to transport liquid substance or pressurize them based on the volume change of the enclosed working chamber. Concretely speaking, it can be used in many occasions. First of all, it is used as the hydraulic dynamical system for many engineering machineries, such as excavator, mechanical loader, pavement roller, bulldozer or crane and so on. At the same time, it can be used to deliver and pressurize fuel during the fuel transfer system. What is more, it also can be a lubricating gear oil pump that is widely applied to many industrial areas.
In order to make sure the high working efficiency and long service life, besides reliable and credible gear pumps manufacturers and gear pumps supplier, maintaining the machine at the fixed intervals is also an effective method. Here are some useful maintenance tips. Before starting up, the tightness of pipeline flange and joint should be checked. The coupling should be made sure no friction noise. Meanwhile, the liquid should be added in the pump if it is the first starting-up. Besides, the valve and electrical machine also should be examined before and after the operation. In order to avoid the oil leakage problem, a control valve had better be installed and it can replace the pipeline between pump and direction valve, which also reduces the cost. Low leakage guarantees reliable operation, too. Parts attrition of gear pump should be paid special attention to, or it will affect the normal working condition. Therefore, the attrition condition should be checked at the fixed period, and replace the wearing ones in time.
