Spiral centrifugal pump is a kind of centrifugal pump that can transport high concentration, high viscosity, easy to caking and suspended particles of liquid.
Main features of Screw pump:
1. Compared with the traditional centrifugal pump, the spiral liquid flow return ring is set between the clamp ring of the spiral centrifugal pump and the pump wheel, which can greatly reduce the surface wear and local blockage that the pump wheel is prone to.
2. The operation of the spiral centrifugal pump is quiet and stable, and does not produce mechanical vibration, so the service life is long.
3. In addition, because this type of centrifugal pump is designed for high concentration and high viscosity liquid, it is designed with a certain pressure cylinder when used, which can inhale gas and pump granular or fibrous materials with a solid particle content of up to 70%.
Screw pump industry:
Spiral centrifugal pump can be widely used in chemical industry, metallurgy, petroleum, paper making, inorganic salts, health and other fields of transportation, discharge of high concentration slurry, oral, textile printing and dyeing, paint, pharmaceutical, papermaking and other enterprises, is an irreplaceable key equipment.
The use and maintenance methods of Screw pumps are as follows:
1. Pre-operation inspection: Before each use, check whether the pump body and pipeline leak, check whether the transmission part is good, sufficient refueling, whether the axial clearance is suitable, and whether the installation is stable;
2. Check before starting: Check whether the electrical system and instrument system are normal before starting. At the same time, connect the suction pipe, pump inlet pipe, discharge pipe and gate valve, and open the exhaust hole to fill the pump body and suction pipe with liquid;
3. Start the motor: start the motor according to the requirements of the electrical system, and then gradually open the outlet valve after about two minutes of observation, so that the pump runs stably;
4. Check during operation: During the operation of the pump, the operation status of the pump should be checked regularly, pay attention to whether the temperature, lubrication and sealing are normal, and it is strictly forbidden to run empty to prevent dry rotation from damaging the shaft sleeve;
5. Treatment after outage: When stopping use, should first close the outlet valve and inlet valve, and then close the motor, clean the internal residual liquid, pour it out from the suction and clean the surface;
6. Maintenance: daily maintenance of the pump according to the working requirements, regular inspection of bearings, mechanical seals and timely replacement of the pump. At the same time, regularly check the lubricating oil, cooling oil, and timely replacement and addition to ensure the reliable operation of the pump.
