Problems solved by technology

Its transmission modes mainly include connecting rod transmission, cam transmission, crankshaft transmission, rocker transmission, wire rope transmission and diaphragm transmission, etc. These transmission modes determine the high stroke frequency, short stroke and displacement adjustment of the reciprocating pump and reciprocating compressor in the traditional system. Difficult, large fluctuations in displacement and discharge pressure, short life of wearing parts, poor suction, difficult to meet the requirements of modern industrial technology levels, and become an urgent problem to be solved in the design, manufacture and application of reciprocating pumps and reciprocating compressors

Embodiment Construction

[0030] In order to further disclose the technical solutions of the present invention, the following will be described in detail through examples in conjunction with the accompanying drawings:

[0031] a. Motor reversing belt drive reciprocating pump,

[0032] like figure 1 , the control system of the motor control cabinet 1 makes the motor 2 rotate forward, drives the nut type pulley 9 to rotate through the belt 3, and the nut type pulley 9 rotates to push the screw type piston rod 8 to run from left to right, and the right end of the screw type piston rod 8 The right piston 7 compresses and discharges the fluid in the right piston cylinder 5, while the left piston 6 on the left side of the screw type piston rod 8 sucks the fluid into the left piston cylinder 4: when the right piston 7 reaches the rightmost side of the right piston cylinder 5, the piston The position sensor sends a signal to the motor control cabinet 1, and the motor control system reverses the motor 2, and d...

Abstract

A motor reversing driving reciprocating pump comprises a motor reversing belt transmission reciprocating pump body or a motor reversing chain transmission reciprocating pump body or a motor reversing gear transmission reciprocating pump body or a motor direct driving type pin roller screw transmission reciprocating pump body or a motor direct driving type ball screw transmission reciprocating pump body or a motor direct driving type rack transmission reciprocating pump body. A motor serves as a power machine and is controlled through a motor control cabinet, so that the operation states, namely the speed regulation and the steering of the motor, of the motor are accurately controlled; the reciprocating motion of the reciprocating pump or a reciprocating compressor is achieved through the forward and backward reversion of the motor, so that the automatic operation with long stroke, low jig frequency, large capacity, high pressure and high efficiency of the reciprocating pump or the reciprocating compressor is achieved, the reliability of the motor reversing driving reciprocating pump is greatly improved, and the service life of the motor reversing driving reciprocating pump is greatly prolonged.

Description

technical field [0001] The invention relates to a reciprocating pump driven by a motor in reverse direction. It is the most important general-purpose mechanical equipment in the industry, and is widely used in various industries such as chemical industry, energy, military, aerospace, electric power, and hydraulic power. Background technique [0002] Reciprocating pumps and reciprocating compressors are widely used in industry and are the most important general-purpose equipment in all walks of life in the industry. They are often used to transport fluids of various capacities, pressures, and performances. However, the traditional reciprocating drive technology is that the power machine (engine or motor) converts the rotational motion of the power machine into linear reciprocating motion through connecting rods, cams or crankshafts. The working principle is: the power machine drives the connecting rod or When the cam or crankshaft rotates at a certain angular velocity, the c...
