Abstract

The invention relates to a variable-frequency multipath pulsating flow generation device, and belongs to the technical field of fluid flow drive control engineering. The variable-frequency multipath pulsating flow generation device comprises a motor, a connection body, a semi-axis valve body, a sleeve, a semi-axis valve element and an end cover. The semi-axis valve body is arranged on the motor through the connection body. The semi-axis valve element is arranged in the semi-axis valve body. The end cover is arranged at one end of the semi-axis valve body. The other end of the semi-axis valve element is connected with the motor through the sleeve. By means of the variable-frequency multipath pulsating flow generation device, the pulsating flow of different asymmetric pulse widths can be controlled to be obtained, the multipath property and the superposition property are achieved, the difficulty that the pulsating flow can not be controlled does not exist, the requirements of engineering for different types of pulsating flow or fluid type pulsation signals can be met, and the engineering quality can be improved; the semi-axis valve element is connected with an output shaft of the motor through the sleeve, and therefore the rotation speed synchronization of the shaft can be achieved, and torque can be effectively transmitted; and the variable-frequency multipath pulsating flow generation device is simple in structure, easy to manufacture, easy and convenient to operate, easy to maintain, high in practicability and capable of avoiding resource waste and environmental pollution.

Description

technical field [0001] The invention relates to a variable-frequency multi-channel pulsating flow generating device, which belongs to the technical field of fluid flow transmission control engineering. Background technique [0002] At present, my country is speeding up the pace of modernization, and fluid transmission technology is of considerable importance in it. Especially after World War II, fluid transmission technology quickly turned to civil industry and was continuously applied to various automatic machines and automatic production lines. With energy shortages and environmental pollution becoming more and more serious, the application of pulsating flow is becoming more and more important in various engineering fields. In many engineering fields, the application of pulsating flow has played a role in energy saving, emission reduction, resource conservation, and environmental protection, and has broad application prospects. [0003] Fluid transmission technology inclu...
