Buying points of large flow gear pump

Publish: Browse:

Large-flow gear pumps can be used as transmission and booster pumps in oil delivery systems; as fuel pumps for delivery, pressurization, and injection in fuel systems; in all industrial fields, they can be used as lubricant pumps.

The large flow gear pump is mainly composed of gear, shaft, pump body, safety valve and shaft end seal. The gear has high hardness and strength after heat treatment, and it is installed in the replaceable sleeve to run with the shaft. The lubrication of all parts in the pump is automatically achieved by using the output medium when the pump is working. The pump has a well-designed drain and oil return tank, which is the smallest torque force that the gear can bear during work, so the bearing load is small, the wear is small, and the pump efficiency is high. 大流量齿轮泵安全阀的全回流压力为泵额定排除压力的1.5倍,也可在允许排出压力范围内根据实际需要另外调整。 The pump is equipped with a safety valve as overload protection. The full return pressure of the large flow gear pump safety valve is 1.5 times the rated exhaust pressure of the pump. It can also be adjusted according to actual needs within the allowable discharge pressure range. However, please note that this safety valve cannot be used for long-term operation of the pressure reducing valve, and can be separately installed on the pipeline when needed. Looking from the extended end of the spindle to the pump, it rotates clockwise.

Pay attention to the following aspects when choosing a large flow gear pump:

1. Select a large flow gear pump from a regular manufacturer. Since the high-flow gear pump requires high technological production and stable performance, it must be produced by a regular manufacturer. At present, the oil pump market is relatively chaotic. Before buying, you must first understand the manufacturer. If conditions permit, you can inspect the factory first.

2. The selection of large-flow gear pumps should be based on working conditions and cost accounting.

3. The large-flow gear pump should be equipped with a spare pump or a set of accessories, so that a pump is available when the pump fails, to avoid the phenomenon of humans and other machines.
