Description
Technical field
The utility model relates to a kind of three screw pump structures suitable for small assembly space.
Background technique
Screw pump is rotator type positive displacement pump, it is to utilize the screw rod theory of engagement, mutual in pump block by the screw rod of rotation
Engagement, transported medium be enclosed in engagement it is intracavitary, be pushed into outlet to continuously and smoothly axially along a screw, provided surely for system
Fixed pressure.Screw pump is suitable for conveying various non-corrosive oils and similar oil and lubricating liquid.
And screw pump is during use, and driving motor is usually required through shaft coupling when connection come real
Now couple, just needs to use the devices such as pedestal, bell-jar when disposing driving motor.And existing screw pump is in application process,
It is frequently encountered the assembly space very little of screw pump, the problem of excessive pump housing of volume is unable to satisfy demand.
Utility model content
The purpose of the utility model is to provide a kind of three screw pump structures suitable for small assembly space, solve existing spiral shell
Bar pump volume is excessive, when assembly space is smaller, cannot achieve assembly, that is, is unable to satisfy the lesser market demand of assembly space
The problem of.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of three spiral shells suitable for small assembly space
Bar pump configuration, including the pump housing form pump chamber in the pump housing, and driving screw rod and suitable with driving screw rod intermeshing is provided in pump chamber
The driven screw matched, pump chamber inner wall are provided with bushing, and the rear end of the pump housing is provided with back shroud, and the front end of the pump housing is provided with front end
Lid, the top end surface of driving screw rod are provided with jack compatible with driving motor shaft, and the shaft of driving motor can be by inserting
Hole, which is inserted directly into driving screw rod, drives driving screw rod rotation.
Further, bushing and the pump housing are integrally formed.
In order to reduce occupied space, the oil inlet of connection pump chamber, the company of offering on the downside of the pump housing are offered on the upside of the pump housing
The oil outlet of logical pump chamber.
The circle of lower sidewalls one at the top of driving screw rod is provided with guiding flange collar, is oriented at the top of flange collar upper surface and driving screw rod
Between form card slot circle, the circle of lower sidewalls one is provided with and be oriented to that flange collar is compatible is oriented to recessed circle at the top of the driven screw,
It is hung at the top of driven screw in card slot circle.
In order to reduce shaft end lubricating oil input, shaft end pressure is reduced, sealing life, driven screw shaft end and active spiral shell are improved
The gap of bar shaft end is 0.02~0.03mm.
The utility model has the beneficial effects that insert compatible with machine shaft is arranged by the top that driving screw rod is arranged in
Hole realizes the direct insertion driving of screw pump, eliminates shaft coupling and dependency structure, can reduce the volume of equipment, reduces empty
Between occupancy, be conducive to save installation space, suitable for requiring use space small and application field at low cost, as gear-box,
Cooler, compressor.Meanwhile oil inlet and oil outlet are set up directly on the pump housing, and it is not arranged in back shroud, on drive end bearing bracket,
So that the thickness of back shroud can greatly reduce, the volume of the entire pump housing has been further reduced.
Below with reference to drawings and examples, the utility model is described in detail.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Embodiment, a kind of three screw pump structure suitable for small assembly space as shown in Figure 1, including the pump housing 1, in the pump housing 1
Pump chamber is formed, driving screw rod 4 and the driven screw 5 with the intermeshing adaptation of driving screw rod 4, pump chamber inner wall are provided in pump chamber
It is provided with bushing, the rear end of the pump housing 1 is provided with back shroud 2, and the front end of the pump housing 1 is provided with drive end bearing bracket 3, the top of driving screw rod 4
End face is provided with jack 6 compatible with driving motor shaft, and the shaft of driving motor can be inserted directly into active spiral shell by jack 6
Driving screw rod 4 is driven to rotate in bar 4.
Bushing and the pump housing 1 are integrally formed.The upside of the pump housing 1 offers the oil inlet of connection pump chamber, and the downside of the pump housing 1 opens up
There is the oil outlet of connection pump chamber.
4 top lower sidewalls one of driving screw rod circle is provided with guiding flange collar, is oriented to flange collar upper surface and driving screw rod 4 is pushed up
It is formed between portion and is affiliated to slot circle, be provided with and be oriented to the compatible guiding of flange collar around 5 top lower sidewalls one of driven screw circle
Recessed circle, the top of driven screw 5, which is hung on, is affiliated in slot circle.The gap of 4 shaft end of 5 shaft end of driven screw and driving screw rod is 0.02
~0.03mm.
The utility model is exemplarily described in conjunction with attached drawing above.Obviously, the utility model implements not
It is limited by aforesaid way.As long as the various unsubstantialities that the method concept and technical solution that use the utility model carry out
Improvement；Or it is not improved, the above-mentioned conception and technical scheme of the utility model are directly applied into other occasions, at this
Within the protection scope of utility model.
