Embodiment Construction

[0017] The device will be further described below in conjunction with the drawings.

[0018] 1. Measuring device structure

[0019] by figure 1 It can be seen that the measuring device only needs to consist of valve seat 1, valve disc 2, spring 3, upper guide rod 4, outer nut 5, inductive frequency modulation displacement sensor power cord 6, inductive frequency modulation displacement sensor signal line 7, and "O" sealing ring 8. Bolt 9, cylinder head 10, inner nut 11, hydraulic cylinder 12, inductive frequency modulation displacement sensor 13, inductive frequency modulation displacement sensor guide rod 14 and other components, among which the working cone of valve disc 2 corresponds to the valve seat 1. Cone fit (when the valve is closed); the waterproof and pressure-resistant inductive frequency modulation displacement sensor 13 is fixed on the cylinder head 10 by threads; the cylinder head 10 uses an "O" seal ring 8, and uses an outer nut 5 and an inner nut 11 Tighten it to...

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. The device installs a displacement sensor on the valve disc of the reciprocating pump, and can directly measure the displacement change of the valve disc of the reciprocating pump during opening and closing. , Used to study the actual movement law of the valve disc of the reciprocating pump, verify the shock-free theory of various pumps and valves, and provide a basis for the design of pumps and valves. The device is equipped with an inductive frequency modulation displacement sensor. The sensor is waterproof and resistant to high pressure. The pump valve cylinder cover is equipped with a sealing device that allows the sensor to pass through and ensures that the pump does not leak. It is also equipped with a self-developed dedicated reciprocating pump. Valve disc displacement test and analysis system. Background technique [0002] The pump valve is one...
