Description
Technical field
The present invention relates to a kind of gear pumps.
Background technology
Gear pump is to convey liquid by the swept volume variation and movement that are formed between pumping cylinder and meshing gear or make
Supercharging drum pump.Two enclosure spaces are formed by two gears, the pump housing and front and rear covers, when gear rotates, are out of gear
The volume in the space of side becomes larger from small, forms vacuum, draws liquid into, the volume in the space of gear engagement side from becoming smaller greatly, and
Liquid is squeezed into pipeline.Suction chamber with discharge chamber is separated by the path of contact of two gears.The outlet of gear pump
Pressure depend entirely on the size of resistance at pump discharge.
Gear pump is also positive displacement devices, i.e., as the piston in a cylinder barrel, when a tooth enters the fluid of another tooth
During space, liquid is just mechanically squeezed and is ejected.Because liquid is incompressible, liquid and tooth cannot be same
Time occupies the same space, in this way, liquid is just excluded.Due to the continuous engagement of tooth, this phenomenon is just continuously occurring, because
And a continuous exclusion amount is also just provided in the outlet of pump, every revolution is pumped, the amount of discharge is the same.With drive shaft
It rotates incessantly, pump also just discharges fluid incessantly.The flow of pump is directly related with the rotating speed of pump.
In fact, there is minimal amount of fluid loss in pump, this prevents the operational efficiency of pump from reaching 100%, because these
Fluid is used to lubrication bearing and gear both sides, and the pump housing also must not blind-mate, therefore cannot make 100% ground of fluid from
Outlet discharge, so a small amount of fluid loss is inevitable.However pump still can be run well, to most of extruded materials
For, can still reach 93%~98% efficiency.
By the study found that existing gear pump structure is complicated, high energy consumption during operating.
Invention content
It is an object of the invention to overcome the deficiencies in the prior art, provide a kind of gear pump herein, including pump cover, washer,
The pump housing, gland nut, gland, driving shaft, airtight and watertight padding, driven shaft, driven gear, screw, driving gear, bolt；With
The prior art, which is compared, has simple in structure, low power consumption and other advantages.
The invention is realized in this way construct a kind of gear pump, it is characterised in that：Including pump cover, washer, the pump housing, gland
Nut, gland, driving shaft, airtight and watertight padding, driven shaft, driven gear, screw, driving gear, bolt；
It is formed a fixed connection between pump cover and the pump housing by bolt in the gear pump, which is formed by pump cover and the pump housing
Overall structure；Gland nut is arranged on the pump housing, and driving shaft one end is located in the pump housing, and the other end runs through gland nut and stretching
Gland nut；Gland and airtight and watertight padding are equipped between driving shaft and pump housing inner wall.
The advantage of the invention is that：The present invention provides a kind of gear pump by improving, including pump cover, washer, the pump housing, gland
Nut, gland, driving shaft, airtight and watertight padding, driven shaft, driven gear, screw, driving gear, bolt；With prior art phase
Than having simple in structure, low power consumption and other advantages.
