Description
Technical field
The utility model relates to the mortar that a kind of conveying abrasion of the enterprises such as ore dressing, metallurgy, chemical industry is big or corrosivity is strong and its
The centrifugal pump of his liquid, in particular to a kind of anti-corrosion centrifugal pump.
Background technique
Past various dressing plants are used to convey the centrifugal pump of mortar, are all made of gray cast iron or wear resistant cast iron manufacture, there is mill
Damage is fast, using the time is short, low efficiency, poor sealing performance, water power consumption more, maintenance and repair heavy workload and operating cost height etc. are asked
Topic.
Summary of the invention
The purpose of the utility model is to overcome defect of the existing technology, it is simple to provide a kind of structure, for ease of maintenaince, makes an uproar
Sound and with small vibration, good seal performance anti-corrosion centrifugal pump.
Realizing the technical solution of the utility model aim is: a kind of anti-corrosion centrifugal pump has pump case and pump cover；The pump cover
It is fixed on pump case by fastener, and there is sealing ring between pump case and pump cover；Pump shaft is equipped in the pump case；The pump case
One end be provided with the preceding wearing plate and rear wearing plate coaxial with pump shaft；It is equipped with and fixes between the preceding wearing plate and rear wearing plate
In the impeller on pump shaft；The side of wearing plate and pump cover is in close contact after described；It is equipped between the pump cover and pump shaft by tight
Firmware is fixed on the stationary seat on pump cover, and the other side of pump cover, which is in close contact, is provided with end cover；It is successively covered on the pump shaft
It is connected to axle sleeve and end seal.
Above-mentioned technical proposal also has accessory impeller；The accessory impeller is located at the right side of impeller, and is integrally formed with impeller.
End seal flushing pipe is connected on pump case described in above-mentioned technical proposal.
Drain pipe is connected on pump case described in above-mentioned technical proposal.
One end of the nearly pump cover of pump shaft described in above-mentioned technical proposal is fixed with Non-return ring.
After adopting the above technical scheme, the utility model have the effect of it is following positive:
(1) the utility model long service life, than the flow passage part service life difference for the pump that general cast iron and wear resistant cast iron manufacture
Improve 10 times or more and 3-5 times.
(2) the utility model performance is good, and characteristic curve is steady, and when changes in flow rate is larger, lift variation is small, pressure weighing apparatus
It is fixed, high efficient band width, while net positive suction head is small, vacuum degree is high, can be used in low, high altitude localities.
