Start Roots vacuum pump unit: 1. Open the intermediate pump and the main pump circulating cooling water inlet and outlet valves, circulating cooling out of the water to ensure the normal 2, close flush the buffer tank pump discharge valve Roots pump, pump water will start to be. normal operation (motor and pump noisy equalization) Hou Luoci pump wholesalers, slowly open the pre-flush pump bypass valve on the pipeline and the Roots vacuum pump inlet valve. 3, until the system pressure reaches the middle of the pump set to allow After the inlet pressure, starting the middle of the pump, such as through the use of automatic control gear, directly appropriated for automatic control block, the boot process will be automated unit 4, such as manual control, when the intermediate pump discharge pressure of the main pump pressure to allow imports, Start the main pump. Roots vacuum is a vacuum pump without internal compression Roots vacuum manufacturer, the compression ratio is usually very low, so high, the need for pre-vacuum pump. By a pair of leaf cavity pump rotor synchronous, urging action of the reverse rotation to move the gas to achieve suction vacuum pump. Roots mechanical vacuum pump means having a pair of soles shaped rotor synchronous high-speed rotation of the pump is not pumping alone, the first stage to be equipped with seals, water ring can be vertical atmosphere.
