Provided is a pump body compensator. A compensator seat is connected to a compensator cover via a compensator seat pad, a bushing is fixed to the compensator cover via a bolt, a pipe is arranged in the compensator seat, one end of the pipe is connected with a compensation valve port, the other end of the pipe is provided with screw plugs, a pipeline is provided with a drain valve port, the bottomof the compensator is provided with another screw plug, the compensation valve port is inserted into a compensation valve, the drain valve port is inserted into a drain valve, and a casing of the compensator is filled with oil. When oil in a pump body is not sufficient, the internal temperature of a pump cavity changes, a pressure intensity difference is generated, and the oil compensation valve of the compensator is opened to supplement oil into the pump body; when the oil in the pump body is excessive and flows out along the pipeline, the oil drain valve is opened by means of a thrust of theoil, and the oil is discharged to the casing of the compensator; when cavitation occurs in the pump body and influences oil compensation, the screw plugs can be opened for venting; and when the oil in the compensator is excessive, the screw plugs can be opened to discharge the superfluous oil. The compensator is simple in structure, convenient to operate, safe and efficient.
Description
technical field [0001] The invention belongs to the technical field of pump body accessories, and in particular relates to a pump body compensator. Background technique [0002] As far as the current pump body compensators are concerned, most of them only have a unilateral compensation function, without considering the overcompensation and other adverse conditions caused by it at the same time. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide a pump body compensator, which automatically compensates and reduces overcompensation according to the change of the air pressure in the pump body, so as to achieve safe and efficient compensation. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A pump body compensator, including a compensator seat, a sleeve, and a compensator cover. The compensator seat is conn...
