Abstract

The invention discloses a device for measuring the valve disc displacement of a reciprocating pump valve. The device consists of a valve seat 1, a valve disc 2, a spring 3, an upper guide rod 4, an outer nut 5, an induction frequency modulation type displacement sensor power line 6, an induction frequency modulation type displacement sensor signal line 7, an O-shaped sealing ring 8, a bolt 9, a cylinder cover 10, an inner nut 11, a hydraulic cylinder 12, an induction frequency modulation type displacement sensor 13, an induction frequency modulation type displacement sensor guide rod 14, an induction frequency modulation type displacement sensor direct current power supply 17, a reciprocating pump flow signal 18, a reciprocating pump pressure signal 19, a data acquisition device 20, a computer and valve disc displacement testing and analyzing system 21 and the like, wherein a valve disc displacement signal output by the induction frequency modulation type displacement sensor 13, the reciprocating pump flow signal 18 and the reciprocating pump pressure signal 19 are transmitted into the computer 21 through the data acquisition device 20 and are processed by the valve disc displacement testing and analyzing system which is autonomously developed, and a change rule of the valve disc displacement of the pump valve under different flows and pressures is obtained.

Description

technical field [0001] The invention provides a device for measuring the displacement of the valve disc of a reciprocating pump pump valve. The device installs a displacement sensor on the valve disc of a reciprocating pump pump valve, and can directly measure the displacement change of the valve disc of a reciprocating pump pump valve during the opening and closing process. , to study the actual movement law of the valve disc of the reciprocating pump, to verify the non-shock theory of various pump valves, and to provide a basis for the design of the pump valve. The device is equipped with an inductive frequency modulation displacement sensor, which is waterproof and high pressure resistant. The pump valve cylinder head is equipped with a sealing device that allows the sensor to pass through to ensure that the pump does not leak, and is equipped with a special reciprocating pump developed by itself. Valve disc displacement test and analysis system. Background technique [...
