Abstract
The utility model relates to a double-cylinder double-gear pump, which comprises a pair of engaged liquid sucking and discharging gears, wherein the gears are contained in a liquid sucking and discharging cavity. The utility model is characterized in that the liquid sucking and discharging gears are coaxially connected with a pair of engaged drive gears; the drive gears are separately arranged in the other transmission cavity. Because driving engaging force of the gears is transferred by the drive gears, and the liquid sucking and discharging gears generate liquid pressure at radial direction because of sucking and discharging liquid, the utility model avoids the abrasion which is generated by the liquid sucking and discharging gears because of the engaging force, reduces the abrasion and increases the service life of the pump. The liquid sucking and discharging gears can be made of engineering plastic and other corrosion resistant material, thereby, the utility model saves material and has low cost.
Description
Technical field
The utility model relates to a kind of gear pump.
Background technique
The full depth tooth wheel pump adopts the pumping element of a pair of gear as fluid, is mainly used in the conveying oil-based liquid, because its processing is simple, convenient, cost is low, the existing sprinkling that also is used for the automation agricultural chemicals.Gear pump comprises the gear of pair of meshing, be contained in the pump housing, the pump housing is provided with liquid entering hole and liquid outlet, meshes between the gear, one is driving gear, another is a driven gear, in motor operation course, because this gear pump is single cavity, transmission and separatory are all in same cavity, if be used to carry waterborne liquid, have certain corrosivity for gear, make that the life-span of the pump housing is extremely short.
The model utility content
The purpose of this utility model is to provide a kind of gear pump, reduces the stressed of gear and wearing and tearing, and can be used for carrying waterborne liquid, and is little or do not have a corrosion to the gear corrosion.
A kind of twin-tub duplex geared pump includes the suction liquid gear of pair of meshing, is contained in the suction sap cavity body; Above-mentioned suction liquid gear also is coaxially connected with the driving gear of pair of meshing, and this driving gear separation is arranged in another transmission cavity.
Above-mentioned suction liquid gear is the gear that plastics or alloy material are made.
Above-mentioned suction liquid gear also can axially connect the pair of meshing suction liquid gear that is arranged in another cavity.
The working principle of above-mentioned structure is: at first power is passed to suction liquid gear by transmission shaft by driving gear, because gear-driven engagement strength is transmitted by driving gear, suction liquid gear only bears suction liquid and the radial hydraulic pressure that produces, the wearing and tearing of having avoided suction liquid gear to produce because of engaging force, reduce wearing and tearing widely, increase the working life of pump; And when wearing and tearing appear in this suction liquid gear, also can not influence the work of pump, and proofread and correct its position by coaxial driving gear.And this suction liquid gear can adopt engineering plastics beyond the metal and other resistant material etc. to make, but economical with materials reduces cost.This pump can be used as the Hydraulic Power Transmission System that Hydraulic power units is used for mechanical field, also can be used as the fluid delivery means and is used for fields such as the energy, chemical industry.Because its cheap cost, be specially adapted to agricultural machinery technological field, agricultural atomizer especially, gear pump becomes highly pressurised liquid with normal pressure liquid, is used for crops such as cotton, fruit tree, flowers and trees are sprayed the worm operation.

Embodiment
As shown in Figure 1, 2, the utility model provides a kind of gear pump, mainly by initiative drive shaft 1, passive transmission shaft 10, a pair of driving gear 2,3, dividing plate 4, a pair of suction liquid gear 5,6, bearing (not looking among the figure), the pump housing 7 are formed, be suction sap cavity body in the pump housing 7, contain the suction liquid gear 5,6 of pair of meshing, by the bearing supporting, this gear adopts plastics to make; Another cavity is the transmission cavity 8 with its isolation, earlier be fixed in dividing plate 4 with screw 91, be fixed on the pump housing 7 of suction sap cavity body by dividing plate 4 usefulness screws 92 again, driving gear includes active driving gear 2 and the passive transmitting gear 3 by the bearing supporting, be supported on the transmission shaft pump housing 7 by transmission cavity 8 and suction sap cavity body successively on the bearing, initiative drive shaft 1 is connected with the motor that is provided with the belt transmission, coaxial active driving gear 2 and a suction liquid gear 5 are separately positioned in transmission cavity and the suction sap cavity body, passive transmitting gear 3 on the passive transmission shaft 10 and initiatively driving gear 2 engagements, it is coaxially arranged with suction liquid gear 6 and another above-mentioned suction liquid gear 5 engagements in the suction sap cavity body.Respectively be provided with an inlet opening 71 and outage 72 on the both sides pump housing of suction liquid gear 5,6 contact pointss.Also be provided with a fixed support 11 on the gear pump body.
Behind the electric motor starting, rotate initiative drive shaft 1, drive initiatively driving gear 2, and transmit with its engagement and be supported on passive transmitting gear 3 on the bearing by active driving gear 2, and drive another coaxial simultaneously to 5,6 rotations of suction liquid gear with it, along with the rotation of suction liquid gear 5,6, the liquid in the suction sap cavity body from the inlet opening 71 of the pump housing move to liquid outlet opening 72, finish the pumping process of fluid.
Above-mentioned suction liquid gear also can axially connect the pair of meshing suction liquid gear that is arranged in another cavity, to increase the fluid pressure in the cavity.
Claims (3)
1. twin-tub duplex geared pump includes the suction liquid gear of pair of meshing, is contained in the suction sap cavity body; It is characterized in that: above-mentioned suction liquid gear also is coaxially connected with the driving gear of pair of meshing, and this driving gear separation is arranged in another transmission cavity.
2. twin-tub duplex geared pump as claimed in claim 1 is characterized in that: described suction liquid gear is the gear that plastics or alloy material are made.
