Embodiment Construction

[0020] This embodiment is a co-meshing Lello triangular rotor pump.

[0021] refer to Figure 1 to Figure 6 , the present embodiment Lello triangular rotor pump consists of driven gear 1, driving gear 2, Lello triangular rotor 3, front pump cover 4, oil outlet 5, pump body 6, oil inlet 7, rear pump cover 8, exhaust Oil cavity 9, oil suction cavity 10 are formed. The three Lello triangular rotors 3 are installed in parallel inside the pump body 5, and the assembly position relationship is as follows: Figure 6 As shown, the assembly position of the rotor 3 satisfies △A 1 B 1 C 1 ≌△A 2 B 2 C 2 ≌△A 3 B 3 C 3 ≌△O 1 o 2 o 3 , and the above four triangles are all equilateral triangles, O 1 , O 2 , O 3 △A 1 B 1 C 1 、△A 2 B 2 C 2 、△A 3 B 3 C 3 center of gravity, A 1 B 1 ∥A 2 B 2 ∥A 3 B 3 . The rotating shaft of the rotor 3 is fixedly connected with three driven gears 1, and the driving gear 2 and the driven gear 1 are installed on the outside of the fro...

Abstract

The invention discloses a same-direction-engaged Lelo triangular rotor pump. The pump mainly comprises a rotor pump shell, three identical Lelo triangular rotors, a driving gear, three driven gears, a front pump cover, a back pump cover and the like. The three Lelo triangular rotors are mounted in a pump body in parallel, and are fixedly connected with the three driven gears on the outer side of the pump body; the driving gear drives the driven gears and the three Lelo triangular rotors to rotate in the same direction to form an oil sucking cavity and an oil pressing cavity; and an oil inlet and an oil outlet are formed in the rotor pump shell. The same-direction-engaged Lelo triangular rotor pump has the following beneficial effects: the linear oil way oil pumping can be realized to shorten the oil pumping route; the pitch of an inclined rotor is changed to control the flow pulsation change, so that the application of the same-direction-engaged Lelo triangular rotor pump to the field of vibration machinery is possible; and the three Lelo triangular rotors are spiral rotors, and an area surrounded by the rotors and the pump body can realize the propeller type oil pumping, so that the rotors cannot be contacted with the inner wall of the pump body to realize the purpose of reducing frictional loss.

Description

technical field [0001] The invention relates to the technical field of gear pumps, in particular to a co-meshing Lello triangular rotor pump capable of pumping oil along a straight line. Background technique [0002] Gear pump is an extremely widely used fluid conveying device in the industry. It has the characteristics of simple structure, small size, light weight, good self-priming performance, pollution resistance, reliable use, long life, easy manufacture, convenient maintenance, and low price. However, ordinary gear pumps use the circumferential direction of the gears as the oil pumping route, and the oil route is long, resulting in a high probability of leakage and easy oil trapping. It is difficult to eradicate. Similarly, the oil circuit of the screw pump is helical and longer. In addition, whether it is a gear pump or a screw pump, the flow pulsation is the object to be eliminated as a defect, and previous researches also point to the direction of no pulsation, wh...
