Structural features of roots pumps

Structural features of roots 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

The role of the roots pump

The role of the roots pump

The roots pump is a vacuum pump with no internal compression, and the compression ratio is usually very low, so high and medium vacuum pumps require a backing pump. It is a vacuum pump that relies on the synchronous and counter-rotating pushing action of a pair of vane-shaped rotors in the pump cham

Installation precautions for roots blowers

Installation precautions for roots blowers

1. Safety protection:Fans should not be installed in places frequented by people to prevent injuries and burns.Avoid installing the fan in places where flammable, explosive and corrosive gases are likely to be produced to prevent accidents such as fire and poisoning.2. Foundations & Foundations:

Roots blower installation steps

Roots blower installation steps

1. Select the installation location:Roots blowers should be installed in bright, dust-free buildings, away from direct sunlight and rain.If it must be installed outdoors, necessary rain and explosion protection measures should be taken, and special attention should be paid to the safety protection o

Roots vacuum pump disassembly and assembly

Roots vacuum pump disassembly and assembly

When disassembling and reassembling the booster pump, the following precautions must be followed:1. Before disassembling the roots vacuum pump, measure and record the clearance of each part of the rotor.2. Try to avoid hitting with a heavy hammer, and the removed parts should not be bruised, and kee

Roots vacuum pump regular inspection

Roots vacuum pump regular inspection

1. Daily inspection:1) Oil level check: too much oil will increase the temperature, and too little oil will cause poor lubrication.2) Temperature check: Check the temperature of each part of the pump with a thermometer.3) Motor load check: measure the motor load with a power meter or current, voltme

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
