Solutions to Common Failures of Slurry Pumps 2

5. The  slurry pump  does not absorb water (no sizing) There is air in the pump body or gas accumulation in the inlet pipe, or the bottom valve is not closed tightly, the water is not full, the vacuum pump packing is seriously leaking, and the gate valve or the flap door is not closed tightly. Remedy: first press up the water, then fill the pump body with water, and then turn on. At the same time, check whether the check valve is tight and whether there is any air leakage in the pipeline and the joint. If air leakage is found, apply lubricant or blending paint to the joint after disassembly and tighten the screw. Check the oil seal ring of the pump shaft, and replace it with new parts if the wear is severe. The pipeline is leaking or leaking. The nut may not be tightened tightly during installation. If the leakage is not serious, cement can be applied to the air leakage or water leakage, or cement slurry mixed with asphalt oil. For temporary repairs, apply some wet mud or...

Solutions to Common Failures of Slurry Pumps 1

1.  Slurry pump  fails to start    First, check the power supply: whether the connection of the connector is firm; whether the switch is tightly connected; whether the fuse is blown; whether the three-phase power supply is missing. If there is an open circuit, poor contact, blown fuse, or phase loss, the cause should be identified and repaired in a timely manner. Secondly, check whether it is a mechanical failure of the pump itself. Common reasons include: the packing is too tight or the impeller and the pump body are blocked by debris; the pump shaft, bearing, and leakage reduction ring are rusted; the pump shaft is severely bent. Remedy: loosen the packing and dredge the water trough; disassemble the pump body to remove debris and rust; remove the pump shaft calibration or replace the new pump shaft. 2. The slurry pump does not turn If the solid deposits in the volute are fouled, measures can be taken to remove the fouling. 3. The flow of the slurry pump is insuff...

Canned motor pump

Image
Canned motor pump Canned motor pump Explosion-proof canned electric pump is a leak-free pump consisting of a canned motor and a pump. The canned pump  has absolutely no leakage. Under negative pressure in the pump, outside air will not be sucked in, which is especially suitable for vacuum system operation; For high pressure, high melting point, high and low temperature media. The canned motor pump is compact in structure, small in size and light in weight; it has no cooling fan, low noise, wide range of use, reliable operation, and can provide a relatively good working environment. Parameters   Capacity: Q up to 1200m3/h   Head: H up to 200m   Fluid Temp. Range: -200 to 450°C ZGPV Canned motor pump   Features   The stator and the rotor are separated by non-magnetic corrosion-resistant thin-walled sleeves. The rotor is supported by the front and rear bearings and immersed in the conveying medium. Therefore, no type of dynamic seal is require...

SK liquid ring vacuum pump

SK liquid ring vacuum pump SK liquid ring vacuum pump SK series water/liquid ring vacuum pumps are widely used in petrochemical, pharmaceutical, food, sugar industry and other fields. Because the gas compression process is isothermal during the working process, it is not easy to compress and pump flammable and explosive gases. It is dangerous and its application is more extensive. Parameters   Flow rate: Q=15~240(m³/h)   Total head: H=1.8~80 (m)   Speed: n=1450/2900rpm   Temperature: T=0~120℃   S.g.: γ≤1.35 Liquid Ring Vacuum Pumps  Features   Since the work generates heat during work, the working water ring will heat up, and at the same time, part of the water and gas are discharged together. Therefore, during the work, the pump must be continuously supplied with water to cool and replenish the pump.   The seal can be mechanically sealed and installed in the packing chamber, and the packing is omitted. The packing gland...
