long-stroke hydraulic cylinder unit
Abstract
The design of long-stroke hydraulic cylinder unit, is a use of motor power,
through a pump, hydraulic cylinder, control unit and hydraulic system composed of metal stents, driven pump of the pump barrel and pump rod for relative movement, complete the role of pumping crude oil. In our existing oil machinery, the mechanical pumping efficiency is low, since the heavy, short stroke, high finished product. Now widely applied in various fields on the beam pumping unit is such a machine. Came into use in the chain unit, although with the 6 m stroke, but from the heavy, low efficiency, high product reliability shortcomings not solve the structural characteristics of poor.
Long-stroke hydraulic pumping unit of work process: from the motor-driven fire pump generator will work the oil through the oil filter, into electric and magnetic valve, the working oil through the slide valve cylinder rod into the working chamber, so that plunger rod upward, with the sucker rod string with it and pump plunger stroke are followed up. Then, the work of the inferior vena tubing cylinder piston oil pressure and oil column above the weight of the heater to the power pump suction port. Cylinder piston moving down the pipeline, together with its tubing string and pump barrel also will down-stroke. Thus, plunger upward stroke, the down-stroke the pump cylinder, pump for discharge of oil process, oil is discharged to ground through the pipe fixed on the casing.
?Simple structure, easy processing, light weight, no big foundation, low cost, long-stroke;
Key words: dual cylinder hydraulic system single-acting cylinder hydraulic pumping unit pump hydraulic cylinder.
