Abstract
The invention relates to a multilevel transmission combination pump which comprises a transmission shaft, a pump shell, a spiral rotor and a liquid transfusion opening. The pump is characterized by also comprising a multilevel gear transmission mechanism, wherein a first level gear of the multilevel gear transmission mechanism is fixed on the transmission shaft; a synchronous gear and the spiral rotor are fixed on a tail level gear of the multilevel gear transmission mechanism, another spiral rotor is also fixed on another synchronous gear rotary shaft, and two spiral rotors are also meshed; and when the spiral rotors rotate, negative pressure is formed at one side of the inner part of the pump shell, positive pressure is formed at the opposite other side, and liquids are delivered from a feed liquid delivery opening of the pump shell to a discharging liquid delivery opening of the pump shell. According to the invention, the rotation speed which is transmitted by a motor in a pump body is reduced directly, a speed reduction box is omitted, the volume is small, and the efficiency of suction and discharge is high.
Description
Technical field
Multistage transmission combination pump belongs to the displacement pump technical field, especially refers to have the multistage transmission combination pump of deceleration.
Background technique
Pump is the common equipment of conveyance fluid, liquid for water and so on good fluidity, output speed is quicker to have no relations, general pump can both be competent at, but liquid such as transport viscosity height, heavy oil that density is big, mud just dying, because transmission power is big, wearing and tearing are big, rotating speed is not soon, the Professional visitors is referred to as displacement pump to the classification of the pump of this low-rotate speed, because require rotating speed slow, must between motor and pump, connect speed reducer, certainly will cause take up an area of bulky, the Installation and Debugging workload is big, also can reduce through-put power when installation precision is not enough.
Summary of the invention
The object of the present invention is to provide a kind of multistage transmission combination pump, directly in the pump housing, the rotating speed of motor transmission is reduced, save speed reducer, reach purpose easy for installation, that volume is little, suction efficient is high.
To achieve these goals, technological scheme of the present invention is as follows:
Multistage transmission combination pump comprises transmission shaft, pump case, helical rotor, infusion port, and transmission shaft is driven by the moment of torsion that motor transmits, and it is characterized in that also having comprised multilevel gear drive mechanism.Described multilevel gear drive mechanism, its first order gear is fixed on the transmission shaft, also coaxial synchromesh gear and the helical rotor fixed of its final stage gear, with also fixed another helical rotor in another synchromesh gear rotating shaft of this synchromesh gear engagement, two helical rotors also are in engagement.In the helical rotor rotation, the side in pump case inside forms negative pressure, forms malleation in a relative other side, liquid is transported to the discharging infusion port of pump case from the charging infusion port of pump case.
When the present invention used, transmission shaft was connected with power source, and by the transmission of multi-stage gear mechanism, rotating speed reduces step by step, can satisfy the needs of carrying thick liquid.Owing to adopted in pump case and slowed down, so compact structure, little, the suction efficient height of volume.Owing to adopt the gear reduction mode, so accuracy of manufacturing and installation precision need not be very high.As long as change the power source sense of rotation, the import and export of the pump housing can be changed mutually, two-way suction.Owing on two helical rotors, synchromesh gear is all arranged at transmitting power, thus the engagement of helical rotor rotation strong and powerful, stablize smooth and easyly, the phenomenon that leakage is flow backwards can not appear during the big liquid of discharge pressure; When transfer of highly viscous, high-lift liquid, the advantage that its suction capacity is strong, discharge pressure is big particularly shows especially.When needing, several multistage transmission combination pumps import and export are serially connected, can obtain higher lift.

Embodiment
Below by drawings and Examples the present invention is further elaborated.
Embodiment: multistage transmission combination pump structure comprises transmission shaft 1 as shown in Figures 1 to 4, pump case 2, infusion port 21, one-level small gear 31, one-level gearwheel 32, secondary small gear 41, secondary gearwheel 42, synchromesh gear A51, synchromesh gear B52, helical rotor A61, helical rotor B62.
Can see that from Fig. 1, Fig. 2 the transmission shaft 1 that has keyway stretches out in pump case 2 outsides, the multistage housing of pump case 2 usefulness is composed of a fixed connection, and is provided with two infusion ports 21 in front and back of receiving fluids turnover on the position of pump case 2 with respect to helical rotor 6.Also be provided with fixedly footing 22 on the pump case 2.
Can see from Fig. 3, Fig. 4, fix one-level small gear 31 in the rotating shaft of transmission shaft 1, intermesh with one-level gearwheel 32; Fixed secondary small gear 41 in the rotating shaft of one-level gearwheel 32, intermeshed with secondary gearwheel 42.Synchromesh gear A51 and helical rotor A61 have been fixed in the rotating shaft of secondary gearwheel 42; Synchromesh gear B52 with synchromesh gear A51 is meshing is fixing helical rotor B62 in its rotating shaft.The tri-lobed that the helical rotor A61 of present embodiment and helical rotor B62 reverse in the shape of a spiral, under the drive of synchromesh gear A51, synchromesh gear B52, intermeshing and rotating, two helical rotors are separated into two zones to pump case 2 inside of corresponding position, one side is a negative pressuren zone, is connecting the charging infusion port of pump case 2; Opposite one side is a zone of positive pressure, is connecting the discharging infusion port 21 of pump case 2.Change the sense of rotation of transmission shaft 1, the position of material feeding mouth and discharge port can exchange.
The above is one embodiment of the present of invention only, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case are for example changed into three grades or more multistage transmission to the secondary transmission, uses to increase speed ratio etc., all falls into the protection domain of this case.
