Acid And Alkali Centrifugal Pump Installation And Maintenance
TIME：2024-06-03 Author：admin Views：
Acid and alkali centrifugal pump installation, use and maintenance of good and bad, directly affecting the use of the machine's efficiency, service life, economic benefits, as well as personal and unit safety, must be paid full attention to.
● Plastic Centrifugal water pump installation
Water pump installation location selection
1. To ensure safety, acid and alkali resistant pumps are installed as close as possible to water sources and steep slopes to shorten the length of the inlet and outlet pipes and reduce unnecessary bends and joints to minimize the possibility of air leakage and loss of head.
2. The vertical height of the water pump from the river surface or the water surface of the inlet pool must be less than the permissible large suction head of the pump at the dry water level, and the unit should not be submerged during the flood season.
3. The foundation for installing the acid and alkali resistant centrifugal pump should be strong and dry so that the pump will not be sunk and the motor damped due to vibration during operation.
4. The location where the pump is installed should have enough working ground for dismantling and overhauling.
Installation of water pump with inlet and outlet pipes
1.The inlet pipe support must be firm, can not fall on the centrifugal pump, the joints should be strictly sealed, no air leakage.
2. Elbow can not be directly connected to the inlet, you must install a section of about 3 times the diameter of the straight pipe,otherwise it will cause turbulence in the water inlet pump, affecting the efficiency of the pump.
3. Inlet pipe with bottom valve should be installed vertically,such as terrain restrictions must be installed diagonally, the angle with the water surface should be greater than 45 degrees,and the direction of the valve shaft should be in the horizontal direction, so as to avoid the bottom valve can not be closed or closed poorly, affecting the efficiency of the pump.
4. Any part of the water inlet pipe should not be higher than the upper edge of the water inlet of the pump to prevent air from gathering inside the pump and affecting the suction effect.
5. In order to reduce power consumption, the outlet pipe of the pump should be as close as possible to the water surface of the pool or submerged below the water surface of the pool, and should not be too much above the pool.
● How to use the acid and alkali pump
Using the centrifugal pump, the following preparations should be made before starting
1. The centrifugal pump should be checked before starting whether the bolts at the fastening places are loose, whether there are abnormal noises, whether the oil quantity at the lubrication parts is sufficient,etc., so as to exclude possible problems as early as possible to avoid losses.
2. The pump should be filled with water before starting. Unscrew the open screw plug before filling, and then add water until water outward from the bleeder hole, and then rotate the pump shaft a few times, if the water continues to rise, indicating that the water has been filled, and then close the bleeder screw plug, ready to start.
Operation and stop of the water pump
1. Precautions for water pump operation. Pay attention to the operation of the power plant, observe the water temperature, oil temperature is normal or not , pay attention to the unit sound and vibration, when the unit vibration is too large or a murmur, the pump issued a failure signal, must be shut down for maintenance to eliminate hidden dangers, water inlet at the mouth of the floating objects, the bottom of the valve submerged in the depth of the adequate, Whether each fastening place is loose, whether the water inlet pipe joints are tight and not leakage.
2. The water pump is stop. When the centrifugal pump is stop, it should be shut-off the outlet valve slowly, gradually reduce the speed of the power machine, so that it is in a light load state, and then stop the power machine.
● Maintenance for centrifugal water pump
Clean the surface of the pump frequantly.
The pump can be lubricated with oil and grease. If lubricated with oil, replace the oil every month, if lubricated with grease, replace the grease once every half a year
Avoid pumping muddy water containing too much sediment, otherwise the impeller , mouth ring and packing and other places are easy to wear.
Before the pump is preserved in winter, we should do a complete overhaul, which includes the power machine,transmission equipment and electrical equipment.
