Water ring vacuum pump working principle (4)

5, Startup and Parking Startup: Long-term parking pump must be rotated by hand for several weeks before it starts, to ensure that the pump is not stuck or other damage. Startup is performed in the following sequence: (1) closing the valve 4 on the intake line; (2) starting the motor (the motor must be steered correctly); (3) opening the valve on the water supply line 6 to supply water to the pump until the specified requirements are met . (4) When the pump reaches the ultimate vacuum or maximum pressure, open the valve on the intake line 4, the pump began to work properly. (5) adjust the packing gland, dripping drops when the water is best. (6) Through the valve to adjust the water supply pump to ensure that the pump in the required technical conditions, so that the minimum power consumption, meet the performance indicators to meet job requirements. (7) Adjust the amount of water supplied to the separator to ensure that the required technical specifications of the pump are used (8) When the pump is operating at its ultimate pressure, the pump may explode due to physical effects, but the power Consumption does not increase, the valve on the intake pipe can be opened to make it into a small amount of gas, the sound of explosions disappear immediately. If the explosion does not disappear, and the power consumption increases, it indicates that the pump has failed and should stop inspection. Parking: Parking in the following order: (1) close the intake pipe valve. (When the compressor is used to close the exhaust valve) (2) Close the water supply valve to stop the water supply to the pump. (3) Turn off the motor. (4) Close the make-up water valve. (5) If the parking time exceeds one day, the water in the pump and separator must be drained to rust. Note: In winter, each long-term parking must be drained of working fluid to prevent cracking equipment. 6, maintenance 1. Often check the bearing work and lubrication bearing under normal working conditions than the surrounding temperature 15 ℃ ~ 20 ℃, the highest not allowed to exceed 55 ℃ ~ 60 ℃, the bearing should be installed 3-4 times a year and Clean at least once to change the oil. If the packing seal, packing should be regularly compressed, if the packing due to wear and tear can not guarantee the sealing performance, the filler should be replaced. Filler can not be pressed too tight, the filler under normal conditions, allowing water droplets drip, so as to ensure cooling and sealing effect. If the mechanical seal, the phenomenon of leakage should check the mechanical seal, static ring is damaged, or the seal has aged, or should be replaced mechanical seal.
