The gas-liquid booster pump is a kind of power conversion machine, which is mainly used in the gas-liquid conversion power station. It is mainly driven by 1-7bar compressed air by using the gas oil conversion method. The compressed air changes low pressure oil into high pressure oil to provide high output. As the gas-liquid conversion power station combines the pneumatic and hydraulic principles at the same time, it has the advantages of fast transmission speed, large output pressure, low working noise, high cost performance, and is a replacement product of modern pressure equipment.
Most of the existing gas-liquid booster pumps are single head single acting booster pumps or double head double acting booster pumps. The single head single acting booster pump is only equipped with a high-pressure booster chamber on one side of the gas drive cylinder, and only when the piston rod moves to one side can high-pressure hydraulic oil be output, and oil cannot be supplied during oil suction, so the flow of the booster pump is relatively small; When the double head double acting booster pump moves on both sides of the piston rod, one side absorbs oil and the other side outputs high-pressure oil, which can provide a continuous oil source. However, its gas drive cylinder has increased length, large volume and high use cost.
In order to solve the problem that the existing single head single acting gas-liquid booster pump cannot achieve low continuous working efficiency, while the double head double acting gas-liquid booster pump has high relative cost, and improve the cost-effectiveness of the gas-liquid conversion power station, in order to solve the above technical problems, the utility adopts the following technical solutions:
The utility model relates to a single head double acting gas-liquid booster pump, which comprises a hydraulic high-pressure part and a pneumatic drive part. The hydraulic high-pressure part comprises a flange gland, a front end cover, an oil inlet check valve, a small cylinder barrel, a small piston, a small piston check valve, a flange, and a transition flange guide end cover; The air drive part includes the front cover of the air drive, the rear cover of the air drive, the large cylinder barrel, the large piston, the front pilot valve, the rear pilot valve, and the pneumatic slide valve. The center of the front cover of the air drive is provided with a through hole.
The guide end cover of the transition flange is connected with the front end cover of the gas drive through the through-hole and screws. The small piston of the hydraulic high-pressure part is located in the small cylinder barrel, and the large piston of the pneumatic drive part is located in the large cylinder barrel. The small piston is connected with the large piston through the piston rod fixed at the center of the piston at both ends. The guide end cover of the transition flange is equipped with a central through-hole. The piston rod passes through the central through-hole and moves left and right. The pneumatic slide valve is located on the upper part of the front end cover of the gas drive.
The single head double acting gas-liquid booster pump proposed by the utility model not only has the characteristics of a single head single acting gas-liquid booster pump with a small structure volume, but also has the characteristics of a double head double acting gas-liquid booster pump that can realize continuous work and high efficiency. In the process of two-way movement of the piston, there will be hydraulic oil output, so the cost is low. Come to our website if you have any needs http://www.allarabandroid.com Ask and understand
