1. The role of Centrifugal Pump
The centrifugal pump refers to the pump of the liquid generated by the centrifugal force produced by the leaf wheel. The centrifugal pump can be widely used in power, metallurgy, coal, building materials and other industries.
Granules slurry. Such as the hydropower of the thermal power plant, the transportation of the slurry of the metallurgical procurement plant, the coal washing plant coal, and the heavy agency transportation. When the centrifugal pump works, the pump needs to be placed on the ground, water absorption pipe
In the water, the pump is also needed to start.
2. How to use centrifugal pump:
1. The steering of the driver should be the same as the steering of the pump.
2. Check the steering of the pipeline pump and the coales.
3. There should be no loose parts of each fixed connection. The specifications and quantities of the lubricant with the lubricant shall meet the provisions of the equipment technology documents.
4. Pre-lubrication shall be pre-lubricated in accordance with regulations.
5. Each indicator instrument, the safety protection device should be sensitive, accurate, and reliable.
6. The car should be flexible, without abnormal phenomena.
7. The pump body should be preheated before the trial transportation, and the temperature should be evenly increased. The temperature rise per hour should not be greater than 50 ° C;
The temperature difference between the pipeline should not be greater than 40 ° C.
8. Set the connection device that eliminates the impact of temperature rise, and set the bypass connection device to provide cooling water sources.
3. Precautions for centrifugal pump operation:
1. It is forbidden to run without water, do not adjust the inlet to reduce the displacement, and it is forbidden to run under too low flow.
2. Monitor the operation process, completely prevent the leakage of the filler box, and use a new filler when replacing the filler box.
3. Make sure that the mechanical seal has full rinse water flow, and the water -cold bearing is prohibited from using excessive water flow.
4. Do not use too much lubricant.
5. Check it according to the recommended cycle. Establish operating records, including running hours, adjustment and replacement of fillers, adding lubricants and other maintenance measures and time.
For centrifugal pumps, suction and emission pressure, flow, input power, the temperature of the washing fluid and bearing, and the vibration conditions should be regularly measured.
6. The host of the centrifugal pump relies on the atmospheric pressure to draw the water at the low place to the high place. The atmospheric pressure can only support about 10.3m of water columns. Therefore
The water surface cannot work 12 meters.
