Embodiment Construction

[0015] The set of devices will be further described below in conjunction with the accompanying drawings.

[0016] 1. Measuring device structure

[0017] Depend on figure 1 It can be seen that the measuring device consists of valve seat 1, valve disc 2, spring 3, upper guide rod 4, signal line sealing device stud 5, signal line sealing device nut 6, cylinder head bolt 7, cylinder head 8, pump head 9, acceleration Sensor signal line 10, acceleration sensor 11 and other components, in which the working cone surface of the valve disc 2 cooperates with the corresponding cone surface of the valve seat 1 (when the valve is closed), this type of valve has a simple structure and the valve seat is effective for flow The area is large, and the hydraulic loss flowing through the valve seat is relatively small; the sensor signal line 10 is led out from the inner cavity of the pump head 9 through the cylinder head signal line sealing device; the cylinder head 8 and the pump head 9 are conn...

Abstract

The device provided by the invention is mainly used for measuring an acceleration of a valve disk in a movement process of a reciprocating pump valve. According to the invention, an acceleration sensor 11 installed on the valve disk of the pump valve is used for measuring an acceleration signal in a reciprocating process of the valve disk, and a signal wire 10 of the acceleration sensor 11 is led out from the inside of the pump valve; signal wire sealing devices (5 and 6) capable of enabling the signal wire 10 of the acceleration sensor to pass through and ensuring that the pump does not leak are arranged on a reciprocating pump cylinder cover 8; the acceleration signal of the pump valve in a movement process is measured by the acceleration sensor 11 installed on the valve disk, is amplified by a charge amplifier 14, is transmitted to a computer and a valve disk movement testing and analyzing system 16 through a data acquiring box 15, and is analyzed and processed by applying a self-developed pump valve disk movement testing and analyzing system to obtain an actual acceleration movement rule of the valve disk of the reciprocating pump valve, and therefore therefore a better experiment technical means and data support are provided for researching the movement rule and the damage mechanism of the valve disk of the reciprocating pump valve.

Description

technical field [0001] The invention provides a set of novel, small and practical device for measuring the motion acceleration of the valve disc of the reciprocating pump valve. and impact force conditions, verify the non-impact theory of various pump valves, and study the damage mechanism of pump valves. The device is equipped with a water pressure-resistant acceleration sensor, and the valve cover is equipped with a sealing device that allows the sensor signal line to pass through to ensure that the pump does not leak, and is equipped with a self-developed special pump valve motion analysis system. Background technique [0002] Reciprocating pump valves (including valve discs and valve seats) perform complex and regular reciprocating motions in high-pressure fluids, and the pump valves are subject to a series of complex force systems. These complex force systems include the gravity of the pump valve disc itself, the pre-tightening force of the spring, the pressure and ero...
