deep well pump is used in the field of dry, sink into the drainage of drilling machinery, also known as oil pump. It is an important part of oil well production equipment in the device, through the tubing and sucker rod into the wells, sank in a certain depth below the liquid level, by swabbing effect of downhole equipment of liquid to the ground in the well. It consists of four parts: the working cylinder, the fixed valve, the valve and the piston.
1. According to the
deep well pump installed in the wells in different ways, can be divided into two types of tubular pump and rod pump.
3. According to whether or not the bushing, the
deep well pump is divided into the whole cylinder pump and the combined pump. A plurality of sections are arranged in the outer cylinder of the combined pump, and the pump cylinder is matched with the piston. The whole cylinder pump is the development direction of
