ã€Pump Network in Asia】 After many years of development and use of the pump, it is also very influential in the international pump equipment. From the international point of view, the pump can be divided into a tube pump, a rod pump, a hydraulic feedback pump Thick pump, long plunger sand control pump, drum sand control pump, anti-air pump bridge, etc., then you will be invited together with the pump network in Asia into the pump classification and characteristics. Suction pump classification and features 1, long plunger sanding pump pumping process similar to the ordinary pump, the pumping process, the well liquid through the bridge into the valve into the lateral oil into the pump assembly, the plunger Pai to the pump. High pump efficiency: As the pump upstream valve cover is always exposed outside the pump cylinder, so the oil flow cross-section is not limited by the pump cylinder diameter, so the oil resistance than the conventional pump small. Plunger downward resistance is also small, high pump efficiency, it is also suitable for pumping heavy oil. 2, Piston sand control pump on the stroke, the sucker rod drives the pump cylinder upward, the oil valve is closed, the pump chamber cavity increases, the pressure drops, the well opens the liquid into the valve into the pump chamber. Down stroke, the pump cylinder down, the pump pressure increases, the valve opens, into the valve closed, the pump liquid into the tubing. Pump cylinder for up and down movement, and the plunger by extension tube fixed to the column. Out of the valve is always above the pump cylinder, stop pumping, to avoid sand buried, sand card. The sand deposited on the annular space between the pump cylinder and the outer tube can be prevented from being withdrawn again. 3, hydraulic feedback thickening pump The pump is composed of two pumps connected in series with different pump diameter, the center tube will be up and down the plunger connected as a whole. On the stroke, the plunger assembly up, between the plunger and the lower pump cylinder ring chamber volume increases, the pressure decreases, the inlet valve opens, the valve in the tubing under the pressure of liquid column closed, well fluid Into the annulus through the inlet / exhaust joints. Down stroke, the plunger assembly down, between the plunger and the lower cylinder tube cavity volume decreases, the pressure increases, ring cavity fluid through the inlet / exhaust joints to close the inlet valve, the oil The valve opens and discharges into the tubing through the inner passage of the plunger. At this point, due to the inlet valve is closed, the pressure of the liquid column within the tubing is applied to the lower plunger through the inlet valve, forcing the plunger to overcome the frictional drag of the heavy oil. Through the above introduction of several types of pump products, we have reason to believe that the pump can remain competitive in this market for a long time, as the global economy continues to improve, the demand for pump products continues to increase, for our pump How to do better, it also needs us to do more work.
