Abstract
The utility models relates to a pneumatic hydraulic oil pump and belongs to a pump which is composed of a pneumatic motor, a working cylinder and a pump head; a power output connecting rod of the pneumatic motor is connected with a piston rod of the working cylinder; an outlet pipeline of the working cylinder is connected with the pump head of the bottom of an oil well; a lower port of an oil pipe is sealed with the shell of the pump head; an oil outlet pipe is arranged on the upper end of the oil pipe. An exhaust one-way valve is arranged on the shell of the pump head inside the closing body of the oil pipe; a suction one-way valve is arranged on the shell of the pump head outside the closing body. The utility model has the advantages of reasonable design, simple structure, reliable mechanical performance, low fault ratio, energy-saving performance, safety, high efficiency and low cost.
Description
Technical field
The utility model belongs to pump, particularly relates to a kind of pneumatic hydraulic pumping unit.
Background technique
Traditional well recovery pumping unit is to drive the reciprocal tractive sucker rod of lever by motor by rocker-arm link to constitute, and is commonly called as the machine of kowtowing.This equipment is widely used in the oil recovery field, technology maturation, and its structural principle does not have to change substantially for a long time.This and the relative development of mechanical ﹠ electrical technology at present generally adopt today of new high-tech technology incompatible, and its deficiency manifests gradually, as existing mechanical equipment is very huge, cost is high, rate of fault is high, energy consumption is big etc.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of pneumatic hydraulic pumping unit is provided.
Pneumatic hydraulic pumping unit of the present utility model comprises that pneumatic motor, clutch release slave cylinder and pump head constitute, wherein the outputting power connecting rod of pneumatic motor is connected with the piston rod of clutch release slave cylinder, the export pipeline of clutch release slave cylinder is connected with the pump head of oil well bottom, the lower end mouth of oil pipe is sealed mutually with the shell of pump head, in the upper end of oil pipe oil outlet tube is arranged.
As further improvement of the utility model, have on the housing of described pump head in the closure of oil pipe on the one-way valve of discharge, the housing outside closure the suction one-way valve is arranged.
Pneumatic hydraulic pumping unit of the present utility model is reasonable in design, simple in structure, reliable in mechanical performance, rate of fault are low, has advantages such as energy-conservation, safe, efficient, low cost.
Description of drawings
Figure of description is the structural representation of the utility model pneumatic hydraulic pumping unit.
