Composition and function of the pressure relief valve

Composition and function of the pressure relief valve

1.The pressure relief valve is composed of a cylinder, a piston group, a protective cover, etc. 2.The cylinder is welded by the left and right end flanges and the cylinder body.3.In order to enhance wear resistance and prevent rusting, the inner surface of the cylinder is plated with hard chrome.4.T

Use and maintenance of pressure relief valves

Use and maintenance of pressure relief valves

During normal operation, the air compressor system pressure should not exceed 7.84×105Pa (8kg/cm2) Frequently check the cylinder, piston, flange connection and pipeline of the pressure relief valve, there should be no air leakage, and the fastening parts should not be loose.A special person should

Installation precautions for roots blower

1. The fan should not be installed in places where people often go to prevent injury and scalding.2. The fan should not be installed in a place that is prone to produce flammable, explosive and corrosive gases to prevent accidents such as fire and poisoning.3. According to the direction of the intak

Structural features of roots vacuum pumps

Structural features of roots vacuum pumps

(1) There is a large pumping speed in a wide pressure range;(2) The rotor has good geometric symmetry, so the vibration is small and the operation is stable. There are gaps between the rotors and between the rotor and the housing, no lubrication, small friction loss, which can greatly reduce the dri

Features of water ring vacuum pumps

Features of water ring vacuum pumps

1.Easy to maintainThe temperature of the compressed gas is low, and the exhaust temperature is only 10~15 °C higher than the inlet temperature, which is easy to be suitable for suction and pressure delivery of flammable and explosive gases.2.Scope of applicationIt is mainly used in coal mining (gas
