After long-term shutdown, the water-ring vacuum pump must rotate the coupling by hand for ten days before starting, so as to confirm whether the water-ring vacuum pump shuts off the cut-off valve on the intake manifold of the pump, and what is the proper way to start it?
Turn off the cut-off valve on the intake manifold of vacuum pump; If the exhaust pipe of the gas-water separator is equipped with the cut-off valve, it should also be turned off; The cut-off valve of the water supply pipeline that opens the omni-directional gas-water separator power supply pipeline leaks water to the height-width ratio of the overflow water pipe to the separation equipment; When the water of the gas-water separator reaches the level of the overflow water pipe gauge requiring the height-width ratio Start the motor when facing.
Open the shut-off valve on the exhaust pipe of the separating equipment, adjust the water flow from the separating equipment to underwater concrete by ball valve, so as to minimize the rated power consumption of the motor within the required technical range, and adjust the shut-off valve for feeding water to the separating equipment, so as to minimize the water flow consumption and ensure the technical standards stipulated by the pump.
Adjust the flow of water to the packing box, so as to ensure the sealing of the packing box by using at least the water flow consumption. When a mechanical pump is in extreme operation, it produces burst sound because of the physical effect in the pump, but the power consumption of the output does not increase as a result. When the burst sound occurs with the increase of the output power consumption, the parking inspection should be given when the pump works abnormally.
