Background technology
Screw pump is engaged spatial volume change and movement to convey liquid or be allowed to increase by what the pump housing and screw rod formed
Pressure, screw pump are divided into single-screw (single screw) pump, Quimby pump, three screw pump and five-screw pump etc., wherein three screw pump fortune by screw rod number
It is most wide with industry.Its operation principle is that on the one hand screw rod is rotated around the axis of itself, another when motor drives pump shaft to rotate
Aspect it again roll along sleeve inner surface, then form the sealed chamber of pump, its screw rod each rotation, seal the liquid of intracavity to
One pitch of front propulsion, with the continuous rotation of screw rod, liquid spiral fashion presses to another annular seal space from an annular seal space,
The pump housing is extruded finally.Machinery of the screw pump as new conveying liquid, with simple structure, safe and reliable, use dimension
The advantages of repairing convenience, go out liquid continuous uniform, therefore application commercially is widely.
Screw pump is used as fuel injection, fuel oil supply and delivery pump in heating equipment.In chemical petrochemical industry and food
Loading, conveying and solution feed pump are used as in industry.Conveying, supercharging, fuel oil injection and grease pump and peculiar to vessel are used as on ship
Hydraulic means pump.Screw pump is widely used in each row such as oil, chemical fibre, metallurgy, machinery, electric power, lathe, ship, glass, highway
Each industry.Screw pump is applied to the lubricating liquid of conveying fuel oil, lubricating oil, hydraulic oil, crude oil, Colophonium and other similar oil.
Screw pump makees lubricating pump in industrial circle, makees hydraulic pump in hydraulic system, conveys and booster pump in fuel system;
Convey in fuel transfer system and gasoline pump.Screw pump is rotator type displacement pump, and it is using the screw rod theory of engagement, by rotation
Screw rod is intermeshed in the pump block, and the medium for being conveyed is enclosed in engagement intracavity, axially along a screw the continuously and smoothly ground row of being pushed into
Outlet, provides stable pressure for system.Screw pump is applied to the various non-corrosiveness oils of conveying and similar oil and lubricity liquid
Body.
Existing screw pump is because structure design, process materials selection and the restriction of problems, have structure not
It is enough simple compact durable, when causing work the screw rod of driving screw rod and driven screw engagement ship row when axial force and centrifugation
Power, radial force are excessive, and power is high, flimsy problem.Especially in thermoelectricity, cement glass building materials, waste incineration and generating electricity, thermoelectricity
In coproduction, the application of rubber tyre plastic industry, the operating mode of dribbling diesel fuel and fuel oil is conveyed, easily because dielectric viscosity is low,
Cause screw rod and screw rod, screw and bushing part is easily because medium lubricity is low and the ability of formation oil film causes holddown, spiral shell
Bar is engaged bushing or screw rod is mutually twisted the phenomenon blocked.
Utility model content
The purpose of this utility model is to provide a kind of durable mesohigh screw pump, solve existing mesohigh screw pump because
Design is not reasonable, there is driving screw rod and driven screw axial force and the Dipeptiven that rubs to the pump housing is big, easily along the bad pump housing and lining
Set so that the problems such as service life of screw pump is too short.
This utility model solves the technical scheme adopted by its technical problem:A kind of durable mesohigh screw pump, bag
Include the pump housing, a driving screw rod being arranged in the pump housing and two driven screws, driving screw rod and driven screw intermeshing it is suitable
Match somebody with somebody, pump housing internal shaping has pump chamber, in pump chamber, be axially provided with bushing, driving screw rod, driven screw are arranged in bushing;Bushing sets
It is equipped with three hole of cooperation being adapted with two driven screws, a driving screw rod;Pump housing axial direction two ends end is before device has respectively
End cap and rear end cap;The pump housing is provided with outlet near the position of drive end bearing bracket, and the position near rear end cap is provided with suction inlet;Before
The inner wall device of end cap has prelocalization set, and driven screw is set in prelocalization set near one end end of drive end bearing bracket inwall;Afterwards
End lid mounted device has top board, and on top board, device has rear positioning sleeve, moves screw rod, driven screw near one end end of rear end cap inwall
It is set in rear positioning sleeve;Prelocalization set, the main part of rear positioning sleeve are arranged in three holes of cooperation.
It is approximately isobaric in order to realize driving screw rod, driven screw two ends, be axially provided with bushing and coordinate three hole positions in
What outlet endface position was connected first draws oily passage;First draws oily passage extends to the bottom of bushing near one end of rear end cap
Portion;It is provided with top board and draws oily passage with second that first draws that oily passage is connected, draws oil with the 3rd that second draws that oily passage is connected
Passage;3rd draw oily channel connection after positioning sleeve inner chamber and driving screw rod, driven screw be adapted.
In order to ensure reliability of structure, rear positioning sleeve includes the main positioning sleeve being adapted with driving screw rod, and driven spiral shell
Bar be adapted from positioning sleeve;Positioning sleeve is overall afterwards and coordinates three holes to be adapted, main positioning sleeve and two sides connected from positioning sleeve
Wall is provided with interior concaved circular cambered surface, and the circular arc being adapted with interior concaved circular cambered surface is provided with from positioning sleeve and main positioning sleeve connecting position
Face.
For the ease of processing, processing cost, simple structure are reduced, it is easy to accomplish, main positioning sleeve and two are from positioning sleeve three
It is separate between person.
Preferably, the material of prelocalization set and rear positioning sleeve is tin bronze, magnalium, magnesium iron, carborundum or ceramics.
Install reliable and stable for the ease of dismantling and ensureing, top board is bolted on rear end cap, and rear positioning sleeve leads to
Bolt detachable apparatus are crossed on top board.
The beneficial effects of the utility model:Prelocalization covers the setting with rear positioning sleeve, can effectively reduce screw rod to the pump housing
With the friction of bushing, and damage of the molecule (such as welding slag) to pump, the service life of pump is improve.In rear end, lid mounted device can
The top board of dismounting so that top board replaces rear end cap directly to bear driving screw rod, driven screw axial force and frictional force to which, has
Effect avoids the damage of rear end cap, while top board is detachable, is easily installed and replaces.First for being connected draw oily passage,
Two draw oily passage, the 3rd draw oily passage so that driving screw rod, driven screw two ends are approximately isobaric, reduce the friction to top board, energy
It is enough effectively to reduce power, vibrations and the noise of pump are reduced, the purpose of energy-conservation is played, while service life can be improved.Prelocalization
Set and rear positioning sleeve improve pump bite-resistant and anti-cavitation surplus it is not enough caused by holddown probability, even if or even enter welding slag or
Foreign body causes holddown, also can protect pump to greatest extent, it is ensured that the destruction of pump block and screw rod minimum level, even if holddown,
Only need to pay screw rod and bushing disassembles taking-up welding slag or foreign body, repeat original performance that assembling can recover pump.And do not affect
Using and the life-span.
