Description
Technical field
The present invention relates to a kind of cleaning tool, and in particular to a kind of screw pump exempts to tear cleaner open.
Background technology
Screw pump is volume type rotor pump, and it is to change to suck by the volume of the annular seal space formed by screw and bushing
With discharge liquid.Screw pump by screw rod number be divided into single-screw (single screw) pump, it is double, three and five-screw pump.The characteristics of screw pump is flow
Steadily, pressure fluctuation is small, have low suction capacity, noise, efficiency high, long lifespan, reliable operation；And its advantage for protruding is conveying
Vortex is not formed during medium, to the sticky insensitive of medium, can transfer of highly viscous medium.Screw pump is by the pump housing and screw rod institute
The engagement spatial volume change of formation and the mobile drum pump to convey liquid or be allowed to supercharging.Screw pump is divided into by screw rod number
Single-screw (single screw) pump, Quimby pump and three screw pump etc..When driving screw rod is rotated, the driven screw that drive is engaged turns together
Dynamic, the screw rod engagement spatial volume of suction chamber one end gradually increases, pressure reduction.Liquid enters engagement space under differential pressure action
Volume.When volume increase to it is maximum and when forming an annular seal space, liquid just in annular seal space one by one continuously along axial movement,
Until discharge chamber one end.At this moment the screw rod engagement spatial volume of discharge chamber one end is gradually reduced, and liquid is discharged.Screw pump
Operation principle is similar to gear pump, simply instead of gear with screw rod in structure.The characteristics of table is various screw pumps and application
Scope.The flow and pressure pulse very little of screw pump, noise and vibration are small, there is suction capacity, but screw rod processing is more difficult.Pump has
Two kinds of structures of single-suction and double-suction type, but single-screw (single screw) pump only has single-suction.Pump must wear safety valve, to prevent because certain is former
Because such as discharge blockage makes the outlet pressure of pump damage pump or prime mover more than feasible value.
During screw pump use, some residues are inevitably piled up in the pump housing, these residues easily cause row
Going out blockage makes the outlet pressure of pump exceed feasible value and damage pump or prime mover, simultaneously because the special structure of screw pump, tears open
It is more complicated that turn on pump body carries out slagging-off.
The content of the invention
The technical problems to be solved by the invention are during screw pump use, one inevitably to be piled up in the pump housing
A little residues, these residues easily cause to discharge blockage makes the outlet pressure of pump exceed feasible value and damage pump or prime mover, together
When due to the special structure of screw pump, taking the pump housing apart, to carry out slagging-off more complicated, it is therefore intended that provides a kind of screw pump and exempts to tear clear open
Reason device, solves the problems, such as the cleaning screw pump inside residue of simple and fast.
The present invention is achieved through the following technical solutions：
A kind of screw pump exempts to tear open cleaner, including with bushing inner wall shape identical scraper plate, be provided with the scraper plate with
The connecting hole of screw rod matching.In the residue for needing to clear up in screw pump, pull down screw rod of screw pump one and be connected with drive device
Connector, by screw rod this head insertion connecting hole, by this cleaner along in the screw rod feeding pump housing, recover screw pump and drive
The connection of device, opens screw pump, and this cleaner is moved in the presence of screw rod and bushing in the pump housing, due to scrape plate shape with
Bushing inner wall shape is identical, and scraper plate is in close contact with bushing, and also just bushing inwall can will be remained in the motion process of scraper plate
On residue scrape, most at last these residues from the port of export discharge.
The connecting hole matched with screw rod is provided with the scraper plate, connecting hole is concentric with the screw sections of junction.Ensure
Bushing and the tight connection of screw rod, enable bushing to be rotated with screw rod.
The connecting hole is connected by ball bearing with screw rod, the connecting hole, is used between ball bearing and screw rod
Interference fit.In machining and manufacturing process, two or more than two mated conditions of part can be divided into roughly slip and match somebody with somebody
Many grades such as conjunction, interference fits and tight fit, interference fit belongs to the one kind in tight fit, that is to say, that the diameter of axle for matching
It is greater than aperture, it is necessary to enter using special tool(s) extruding, or using the characteristic expanded with heat and contract with cold, hole is heated, take advantage of borehole enlargement,
Be set on axle rapidly, two parts just tightly match somebody with somebody integrator after contraction to be cooled, using interference fit ensure that connecting hole,
Bonding strength between ball bearing and screw rod, meanwhile, it is also more convenient when dismounting is needed.
Through hole is also provided with the scraper plate, filter screen is provided with the through hole.Through hole is provided with scraper plate can be ensured
The normal work of screw pump is not influenceed during using this cleaner, it is ensured that the normal circulation of the gas-liquid in the pump housing, meanwhile, in through hole
The upper filter screen that sets ensure that the residue of scraper plate hang-up will not continue to remain in the pump housing by through hole.
The present invention compared with prior art, has the following advantages and advantages：
1st, a kind of screw pump of the invention exempts to tear cleaner open, can not disassemble the residue that the screw pump pump housing is just cleaned out in the pump housing；
2nd, a kind of screw pump of the invention exempts to tear cleaner open, is connected using interference fit, simple structure, is easy to dismounting.
