Abstract

The invention provides an adjustable automatic air injection device capable of reducing pump cavitation damage. The adjustable automatic air injection device comprises an air inlet pipe, a ball valve, a valve cavity, a valve element and a compression spring. The air inlet pipe comprises a first section, a second section and a third section, wherein the second section is perpendicular to the third section. The ball valve is arranged on the second section. The valve cavity is formed in the third section. The compression spring is fixedly installed at the bottom of the valve cavity. The upper end of the compression spring is fixedly connected with the valve element. The diameter of the valve element is larger than that of a valve opening of the valve cavity. The adjustable automatic air injection device is simple in structure, small in size, low in cost, and capable of effectively reducing the cavitation damage.

Description

technical field [0001] The invention belongs to the field of pump cavitation, and in particular relates to an adjustable automatic gas filling device which reduces the harm of pump cavitation. Background technique [0002] Pump is an important general-purpose machine, which is widely used in various industries. However, due to the use environment and partial operation, pumps are prone to cavitation in practical applications. Pump cavitation will cause performance degradation, vibration noise, impeller cavitation and other hazards, which seriously affect the stability and reliability of pump operation. Therefore, reducing the hazard of pump cavitation is an important aspect of engineering design. After retrieval, the patent application number 201410024440.0 proposed "a device for controlling pump cavitation", which judges the development status of cavitation in the pump by monitoring the inlet pressure, and uses a pump or compressor to fill the suction chamber of the pump wit...
