Description
Technical field
The invention belongs to water pump processing technique field, more particularly, to a kind of knife tower.
Background technology
Water pump is very conventional in the modern life as a kind of machinery for conveying liquid or being pressurized liquid.Water pump will
The mechanical energy of prime mover or other external energies transmission liquid so that liquid energy of itself in the presence of external energy increases
Add, in daily life, water pump, which is mainly used to conveying, includes water, oil, acid ＆ alkali liquid, emulsion, suspended emulsion and liquid metal etc.
Liquid, there is very big use value.
Water pump can also convey liquid, admixture of gas and the liquid containing suspended solids simultaneously.The technology of pump performance
Parameter is mainly flow, suction, lift, shaft power, water-horse power and efficiency；Volumetric water can be divided into according to different operation principles
The types such as pump, vane pump.Displacement pump is to transmit energy using the change of its swept volume of a single chamber；Vane pump is to utilize rotary vane
Energy is transmitted in interaction with water, there is the types such as centrifugal pump, axial-flow pump and mixed-flow pump.
Because the volume of water pump is larger, the cutter employed in the process of reality needs to be adapted with water pump, institute
Cutter is also relatively large so that larger amplitude can be produced in the process of water pump, so as in process to water
The positioning requirements of pump are larger, and position level also just represents level of processing；Situation of the processing technology of water pump in position inaccurate
It is lower easily to produce casting flaw, and casting flaw easily causes and cavity or crack is produced in pump runner so that water produces when flowing
Vortex and cause energy loss, so as to hydraulic efficiency reduce, cause energy to transmit well.
Water pump is due to throughout the year under the washing away of current simultaneously so that water pump runner inner wall and impeller flow surface become it is coarse not
It is flat, the coefficient of friction resistance increase of water pump inner flow passage, along with flow velocity of the water in pump is very big, loss of flood peak increase, hydraulic efficiency drop
Low, this allows for water pump in process of production, inwall and impeller is needed preferably to be polished so that inwall is in water flow process
In can bear more to wash away, there is more preferable wear-resistant coefficient.
Simultaneously because after water pump usage time length, the abrasion of pump shaft bolster bearing chamber, the abrasion of bearing position, the pump housing often occurs
Fracture breaks, cavitation (in, erosive wear etc. so that increase in leakage caused by mechanical wear and resistance, so as to volumetric efficiency
Reduced with mechanical efficiency, after there is above mentioned problem, enterprise's conventional solution is to machine after repair welding or brush plating to repair, but two
There is certain drawback in person, so the initial buff precision of water pump is particularly important.
Conventionally, as the size of water pump is generally larger so that the radius of turn of sanding apparatus is larger, so that
Shake occurs in bruting process, influences the size polishing precision of water pump, simultaneously because the size of sanding apparatus is larger, is dismantling
During it is extremely inconvenient, be unfavorable for the replacing of cutter.
