Abstract

The invention relates to an automatic clearance compensation verification test device for a secondary seal of a plunger. The device comprises a device shell bracket, two bearing bases, a central shaft, an eccentric wheel, a bearing bush, a connecting rod, a plunger pin, a plunger pin roller, a plunger cylinder body, a cylinder body end cover, a sealing ring, an electric eddy sensor and a micro flow meter, wherein the eccentric wheel in an eccentric mechanism is connected with a stepped shaft through a flat key. The eccentric distance of the eccentric wheel is the stroke of a plunger pump, and different eccentric wheels can be replaced according to different stroke demands of different plungers under detection without replacing the entire eccentric shaft, thereby reducing the detection cost. Friction between the connecting rod and the eccentric wheel is reduced through the bearing bush, thereby greatly reducing the size and weight of the device. The device has the advantages of simple structure, small number of control elements, convenience in replacing the plunger and a cylinder sleeve, low processing and detection costs, light weight and safety.

Description

technical field [0001] The invention relates to a mechanical device for measuring the gap automatic compensation effect of a water hydraulic plunger pump, which belongs to the technical field of hydraulic components. Background technique [0002] Hydraulic transmission technology is a new technology that directly replaces mineral oil with natural fresh water or sea water as the working medium of the hydraulic transmission system. This technology has outstanding advantages such as cleanness, environmental protection, safety, cheapness, energy saving and pollution-free, and can be widely used in nuclear energy. , marine, firefighting, hydro jetting, etc. Water hydraulic pump is an indispensable energy component in water hydraulic equipment. Its main function is to convert the mechanical energy of the prime mover into hydraulic energy of water, and provide liquid with a certain pressure and flow to the hydraulic system. With the advancement of science and technology and environ...
