Abstract

The utility model relates to a three-blade rotor type high-efficiency thick oil pump. A transmission case (2) is fixed on a base (1) of the three-blade rotor type high-efficiency thick oil pump; a pump housing (3) is fixed at the left end of the transmission case (2); medium incoming and outgoing mouths (4) are formed at the front end and the rear end of the pump housing (3); a driving shaft (5) and a driven shaft (6) are horizontally mounted in the transmission case (2) by bearings; a driving gear (7) and a driven gear (8) are fixed at the right ends of the driving shaft (5) and the driven shaft (6) respectively; the driving gear (7) is engaged with the driven gear (8); the diameters and number of teeth of the driving gear (7) and the driven gear (8) are the same; the driving gear (7) and the driven gear (8) are located in the transmission case (2); two engaged three-blade rotors (9) are fixed at the left ends of the driving shaft (5) and the driven shaft (6) respectively; the sizes and structures of the two three-blade rotors (9) are the same; and the two three-blade rotors (9) are located in the pump housing (3). The pump adopts the three-blade rotors, is high in rotating speed, low in pulsation, large in displacement, high in efficiency and good in generality, and adapts to a wide medium scope.

Description

Three vane rotor formula efficient thick-oil pumps

Technical field

The utility model belongs to the rotor pump technical field, is specifically related to a kind of three vane rotor formula efficient thick-oil pumps.

Background technique

The rotator type thick oil pump adopts two vane rotors at present, and its rotating speed is low, and pulsation is big, and discharge capacity is little, and efficient is low, and fed sheet of a media is single, and versatility is poor.

The model utility content

The technical problem that the utility model solves: a kind of three vane rotor formula efficient thick-oil pumps are provided, adopt three blade rotors, the rotating speed height, it is little to pulse, and discharge capacity is big, the efficient height, it is wide to adapt to the medium scope, and versatility is good.

The technical solution adopted in the utility model: a kind of three vane rotor formula efficient thick-oil pumps, have pedestal, transmission case is fixedly arranged on the described pedestal, the left end of described transmission case fixedly has pump case, and the rear and front end of pump case all has the medium import/export; Driving shaft and driven shaft are installed in the transmission case by the bearing level, and the right-hand member of driving shaft and driven shaft fixedly has driving gear and driven gear respectively, and driving gear is meshed with driven gear and the two diameter is identical with the number of teeth and be arranged in transmission case; The left end of driving shaft and driven shaft fixedly has two intermeshing three vane rotors, and the size of two three vane rotors is identical with structure and be arranged in pump case.

Described driving shaft be positioned at driven shaft under, and the driving shaft right-hand member extends to outside the transmission case right end cap.

The utility model advantage compared with prior art:

1, adopt three blade rotors, stability of rotation, it is little to pulse, and noise is low, and vibration is compared two blades and is increased the service life more than one times down.

2, rotating speed height (two blade type per minute 120-180 change, three blade type per minute 160-240 change) match power is little, finishes with flow medium transport energy consumption lowly, compares two blades energy-conservation 30%.

3, adapt to medium scope wide (mooring in the 30-300000) and can carry thick medium, also can carry sparse medium, can water, oil, vapour mixes defeatedly, is not afraid of silt and granule.

4, three blade rotors can turn round by positive and negative direction, adapt to different installation positions, and its performance is unaffected.

5, active chamber and easily damaged parts concentrate on pump housing afterbody, are convenient to maintenance and change easily damaged parts, prolong the product life cycle.

6, adopt the full closed pump housing, can adapt to abominable working environment, can open-air open-air work.

Embodiment

Below in conjunction with accompanying drawing 1,2 a kind of embodiment of the present utility model is described.

A kind of three vane rotor formula efficient thick-oil pumps have pedestal 1, on the described pedestal 1 transmission case 2 are arranged fixedly, and the left end of described transmission case 2 fixedly has pump case 3, and the rear and front end of pump case 3 all has medium import/export 4; Driving shaft 5 is installed in the transmission case 2 by the bearing level with driven shaft 6, and the right-hand member of driving shaft 5 and driven shaft 6 fixedly has driving gear 7 and driven gear 8 respectively, and driving gear 7 is meshed with driven gear 8 and the two diameter is identical with the number of teeth and be arranged in transmission case 2; The left end of driving shaft 5 and driven shaft 6 all fixedly has three vane rotors 9, and the size of two three vane rotors 9 is identical with structure and be arranged in pump case 3.Described driving shaft 5 be positioned at driven shaft 6 under, and driving shaft 5 right-hand members extend to outside transmission case 2 right end caps.

Driving shaft 5 right-hand members connect with power plant by coupling during use, during work, driving shaft 5 drives driven shaft 6 by driving gear 7 and driven gear 8 engagements, and then make driven shaft 6 and driving shaft 5 drive two intermeshing three vane rotors 9 that are positioned at pump case 3 simultaneously to rotate synchronously, change volume between the two, thereby the import/export 4 of medium from an end sucked, discharge from the import/export 4 of the other end.

Above-described embodiment is preferred embodiment of the present utility model, is not to limit the utility model practical range, so all equivalent variations of being done with the described content of the utility model claim all should be included within the utility model claim scope.
