In order to make the purpose, technical scheme and advantages of the utility model diaphragm compressor more clear, the following will be a detailed description of the utility model’s acetylene automation technology scheme. Obviously, the embodiment described is only a part of the embodiment of the utility model, not the full embodiment. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in the art without making creative labor fall into the scope of protection of the utility model.
The utility model provides a compensatory oil pump for a diaphragm compressor, including an oil pump body, the lower end of the oil pump body is connected with an intake valve, the oil pump body is arranged on one side of the oil intake, and the oil pump body on the opposite side of the intake is set up on the drain valve, the oil intake valve The top is set with an drain valve stop, the drain valve stop is connected to the plunger by spring, the side of the oil intake valve is set with two o-type seals, and the top end face of the inlet valve 2 is arranged between the top end face of the oil pump body and the step surface inside the oil pump body is set for sealing the first gasket.
The upper part of the oil pump body is also embedded in a plunger sleeve, the top of the plunger sleeve is arranged with a plunger cap, the plunger cap is fixed to the oil pump body by the cross-head screw; the plunger is located in the plunger sleeve, and the column may move up and down in the plunger sleeve. The plunger sleeve is sealed with a J-type seal between the plunger sleeve and the plunger. The bottom thread connection of the inlet valve is connected with a lock-tightening cap. The locking cap is used for locking the inlet valve. A second gasket is arranged between the lock-pressing cap and the lower end surface of the oil pump body. The oil pump body is also set up with a spring seat, the spring seat is located between the drain valve stop and the spring.
Acetylene compressor oil in the upper journey of the plunger enters by the inlet, through the inlet valve and drain valve stop into the volume chamber at the lower end of the plunger, in the plunger travel will be the volume of the compressor oil in the volume room discharged from the drain
valve; In the process of drainage, if the pressure is too large, the oil leakage situation may occur, and the use of the top end of the oil injection valve to set the gasket technology scheme can effectively avoid the defects of oil leakage.
The utility model is not limited to the above-mentioned best embodiment, the average technical personnel in the field in this utility model under the indication can be derived from other forms of products, but regardless of its shape or structure to make any changes, all with the same or similar technical solutions as this application, are within the scope of protection of the utility model.
