Phenomenon, affects quality and the life-span of water ring pump.
Utility model content
The resistant material that this utility model overcomes on existing corrosion resistant water ring pump pump housing inwall is easily deformed, easily
Split away off from pump housing inwall, affect the normal deficiency used of water ring pump, it is provided that a kind of steel mesh water ring pump, pump housing inwall
On resistant material good with the bonding strength of the pump housing, be unlikely to deform, resistant material is difficult to split away off from pump housing inwall,
The quality of corrosion resistant water ring pump is good, and service life is long.
In order to solve above-mentioned technical problem, this utility model by the following technical solutions: a kind of steel mesh water ring pump, including before
End cap, protecgulum, the pump housing, bonnet, rear end cap, rotating shaft, impeller, impeller is arranged in rotating shaft, and impeller is arranged in the pump housing, the pump housing two
End inward flange is equipped with liner groove, and pump housing inwall is equipped with dovetail groove near two liner groove location, and liner groove bottom is all laid
Having several reinforced holes connected with dovetail groove, pump housing inwall is provided with the counter sink that some circles connect, countersunk head with pump housing outer wall
The diameter of outer end of hole, more than inner diameter, pump housing inwall is lined with corrosion resistant layer, corrosion resistant layer lining full liner groove, dovetail groove, reinforcement
Hole, counter sink.
Being lined with corrosion resistant layer on pump housing inwall, increase the corrosion resistant performance of water ring pump, some circle counter sinks are constituted on the pump housing
Mesh-like structure, corrosion resistant layer organically combines with the pump housing of mesh-like structure, inseparable, it is to avoid corrosion resistant layer is from the pump housing
Split away off on inwall.The dovetail groove at pump housing two ends, liner groove, the setting of reinforced hole, improve corrosion resistant layer two ends and the pump housing
Bonding strength, makes corrosion resistant layer two ends inseparable with the pump housing.Corrosion resistant layer on the pump housing inwall of this steel mesh water ring pump and the pump housing
Bonding strength good, be unlikely to deform, corrosion resistant layer is difficult to split away off from pump housing inwall, improves the quality of water ring pump, extend
Service life.
As preferably, liner groove bottom is obliquely installed radially inward towards pump housing outer end.Liner groove bottom is obliquely installed, to resistance to
Rotten layer serves spacing effect, avoids corrosion resistant layer to split away off from the pump housing further.
As preferably, corrosion resistant layer both ends of the surface are concordant with pump housing both ends of the surface respectively.This structure arranges and guarantees the whole pump housing
Corrosion resistant performance, the layout simultaneously facilitating the pump housing is installed.
As preferably, pump housing rear and front end is connected with protecgulum and bonnet respectively, and connecting between the pump housing and protecgulum has front dividing plate,
Being connected between the pump housing with bonnet and have rear bulkhead, front dividing plate and rear bulkhead are equipped with a circle stopper slot, pump towards pump body end surface edge
The clamping of body two ends is spacing between two stopper slots.The pump housing is connected between two stopper slots, easy to connect reliably.
Compared with prior art, the beneficial effects of the utility model are: the corrosion resistant layer on the pump housing inwall of steel mesh water ring pump
Good with the bonding strength of the pump housing, it is unlikely to deform, corrosion resistant layer is difficult to split away off from pump housing inwall, improves the matter of water ring pump
Amount, extends service life.
