I. Roots vacuum pump installation
(1) The Roots vacuum pump should be installed in a dry, well-ventilated and clean place.
(2) The ambient temperature of the Roots vacuum pump is 5-40℃.
(3) The Roots vacuum pump should be installed horizontally, and there should be enough space around it to facilitate the Daily inspection and maintenance. Easy to assemble and disassemble.
(4) After turning on the power, the direction of the motor should be in accordance with the direction indicated by the direction arrow on the pump.
(5) The pipe connecting the pumped container should be clean. There should be no foreign matter such as impurities, and the aperture should not be Smaller than the diameter of the pump port, the length should be short to ensure that it has sufficient conduction capacity, and the pipeline connection should be sealed without leakage.
(6) The pumped gas should have no granular solids entering the pump cavity.
(7), the connection between the Roots vacuum pump and the backing pump should be equipped with an elastic tube to reduce the amount of the backing pump vibration caused.
(8) The electrical equipment must have an interlock protection device. When the front pump stops working, the Roots The pump must be stopped at the same time.
(9) The small pump can be started directly, and the large pump must be equipped with a starter.
Instructions for Roots vacuum pump:
Check the oil level after the new pump is in place. The oil level on the gear side is immersed in oil for 3-5 The tooth is suitable, the center of the oil window is slightly higher on the motor side, the oil cup on the shaft extension should not be short of oil, and the lubricating oil of each part is the No. 1 vacuum pump oil.
1. Roots vacuum pump startup procedure: strong>
(1), start the backing pump.
(2), open the valve of the foreline pump pre-pump and the Roots pump intake valve on the mouth.
(3) After the pressure in the system reaches the allowable pressure of the Roots vacuum pump, close the pre-pumping Valve, start the Roots vacuum pump. If there is no pre-pumping pipeline and valve, start the Roots vacuum pump after reaching the starting pressure. This process can also be automatically controlled by a pressure sensor to realize the automation of the whole process.
(4) According to the actual situation of the vacuum system, if it is not a large vacuum system, start the front stage After pumping, the Roots vacuum pump can be started. If it is a larger vacuum system, although the Roots vacuum pump with relief valve has overload protection, this protection is only for the protection of the motor, and the Roots pump itself can still be overheated because it works under high pressure for a long time. If it is stuck, the Roots pump should be started after the foreline pump reaches a certain pressure.
2. Roots vacuum pump shutdown procedure: strong>
(1), close the intake valve of the Roots vacuum pump.
(2), stop the roots vacuum pump step by step from top to bottom, and finally stop the fore pump, It is strictly forbidden to make mistakes in the parking procedure.
(3) After the foreline pump is stopped, immediately deflate the air inlet of the foreline pump.
