Slurry pump and its parts and wearing parts is pump spare parts in common categories, when the pump required processing medium containing a certain amount of solid particles, medium will pump spare parts over-current components are wear resistance, the water pump over-current components requires the use of wear-resistant materials, such that the pump is slurry pump.
Slurry pump with wide application range, such as ore dressing plant, power plant, aluminum oxide, copper factory and mining enterprises will use to the slurry pump, its main role is as the cyclone flotation, magnetic separation equipment such as conveying slurry. Slurry pump 's main structure is divided into the pump body, shaft and driving part three.
A slurry pump.
Slurry pump used for the double pump shell structure, which comprises a pump body and a pump cover and pump shell, impeller, sheath, the front guard plate, a rear guard board is composed of the internal pump shell structure. Slurry pump and pump shell structure made of gray iron, ductile iron, cast steel three, the internal pump shell structure is also known as the water pump over-current components, manufacturing materials also have three, respectively, KMTBCr26, Cr15Mo3 and rubber.
Slurry pump in the pump shell structure is also the flow components in the pump spare parts, the core manufacturing the share of the cost is very high, this also means that it represents the core quality level of slurry pump, slurry pump is selected to be part of the first expedition.
Pump spare parts over-current components manufacturing material, KMTBCr26 metal fine grain size, good wear resistance, high cost, and 70% of the slurry pump flow components make this material. Cr15Mo3 material in the flow components while higher hardness, better abrasion resistance, service life can reach 1.5 times KMTBCr26, but its cost is higher at KMTBCr26 2 times, so the price is relatively low, the use of a smaller range. Rubber in three kinds of manufacturing material better corrosion resistance, when the medium containing solid particles in a sleek, no sharp corners, slurry pump head does not exceed 40 meters, appropriate choice of rubber manufacturing flow components.
The two slurry pump shaft seal.
Slurry pump shaft seal is divided into packing seal, vice impeller seal, mechanical seal three.
The 1 slurry pump packing seal
Slurry pump packing seal on the packing and the shaft sleeve between the soft and hard running plays the sealing effect, packing need to add water, seal water pressure must exceed slag slurry pump outlet pressure 1.5 kilograms, the sealed type in ore dressing plant, coal preparation plant wide application.
The 2 slurry pump auxiliary impeller sealing
Slurry pump auxiliary impeller sealing by vice impeller generates pressure to the sealing effect, requirements for slurry pump flowing pressure does not exceed the slag slurry pump outlet pressure 15%, when the user is deficient of water natural resources uses the sealing method.
The 3 slurry pump mechanical seal
Slurry pump mechanical seal mechanical seal ring tightly by static friction to seal, mechanical seal and divided into an injection type mechanical seal, mechanical seal, water injection type flushing water injection type internal flushing mechanical seal three. No water type mechanical seal does not need to add water, using life of about 4000 hours; water injection type washing machine seals need to add water, water pressure of 1.5 kg, the service life of about 6000 hours; water injection irrigation in mechanical seals need to add water, seal water pressure than slag slurry pump outlet pressure 1.5 kilograms, the use of life of about 8000 hours.
Three. The transmission part of slurry pump
Slurry pump transmission part comprises a pump shaft, bearing, bearing box. On the bearing lubrication. We can use grease lubrication and oil lubrication in two ways, generally in slurry pump delivery medium temperature is higher or slurry pump of the larger cases, require the use of dilute oil lubrication and strengthen the freezing water.
