CN202082140U - Leakage-free high-efficiency double suction pump - Google Patents

Abstract

The utility model discloses a leakage-free high-efficiency double suction pump which comprises a pump body (1), a pump cover (5) and a rotor part (4), wherein a sealing part (7) and a bearing part (8) are arranged at a driving end of the rotor part (4); a sleeve bearing (3) is sleeved at a non-driving end of the rotor part (4) between the pump body (1) and the pump cover (5); an end cover (2) is used for statically sealing the non-driving end of the rotor part (4) with the pump body (1) and the pump cover (5); the sleeve bearing (3) is used for bearing a radial force of a pump; the bearing part (8) is used for bearing an axial force as well as a radial force of the pump; the sealing part (7) is used for shaft sealing of the pump; the non-driving end is statically sealed with end faces of the pump body (1) and the pump cover (5) by the end cover (2); and the function of conveying liquid is realized after the rotor part (4) is driven. The leakage-free high-efficiency double suction pump has the advantages of strong bearing capacity, non-leakage, compact structure, high efficiency, capability of saving manufacturing cost as well as running cost of a water pump, and stability in running.

Description

A kind of nothing is leaked the efficient double-suction pump

Technical field

The utility model relates to a kind of double suction pump, particularly relates to a kind of nothing and leaks the efficient double-suction pump.

Background technique

Traditional double suction pump drive end and anti-drive end all adopt rolling bearing, and sealed member must be adopted in the two ends of pump.Complex structure, the manufacture cost height of water pump, the fault point of water pump operation is many, and is difficult in maintenance.

The model utility content

Technical problem to be solved in the utility model provides strong, stable, the leak free nothing of a kind of bearing capacity and leaks the efficient double-suction pump.

In order to solve the problems of the technologies described above, the nothing that the utility model provides is leaked the efficient double-suction pump, comprise the pump housing, pump cover and rotor part, the drive end of described rotor part is provided with sealed member and bearing part, be provided with sleeve bearing between the anti-drive end of described rotor part and the described pump housing and the described pump cover, the anti-drive end of described rotor part adopts end cap and the described pump housing and described pump cover static seal.

Adopt the nothing of technique scheme to leak the efficient double-suction pump, the pump housing and pump cover constitute the runner of water pump, the radial force of sleeve bearing bearing pump, and bearing part is the axial force of bearing pump both, again bearing radial force.Sealed member is used for the axle envelope of pump, and anti-drive end adopts end cap and pump housing end face static seal.Rotor part is driven the function that liquid is realized carrying in the back.

Compare with original technology and to have following advantage:

Anti-drive end adopts sleeve bearing, and bearing capacity is strong.Anti-drive end adopts end cap and pump housing end face static seal, does not have to leak.

In sum, the utility model is that a kind of bearing capacity is strong, do not have to leak, and compact structure, the efficient height can be saved water pump manufacture cost and operating cost, and stable nothing is leaked the efficient double-suction pump.

Description of drawings

Fig. 1 is the utility model structural representation.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Referring to Fig. 1, the drive end of rotor part 4 is provided with sealed member 7 and bearing part 8, be provided with sleeve bearing 3 between the anti-drive end of rotor part 4 and the pump housing 1 and the pump cover 5, the anti-drive end of rotor part 4 adopts end cap 2 and the pump housing 1 and pump cover 5 static seals, an arm that is located at the wash tub pipe parts 6 on the pump cover 5 is communicated with sealed member 7, and another is connected between end cap 2 and the sleeve bearing 3.

Referring to Fig. 1, the pump housing 1 and pump cover 5 constitute the runner of water pump, the impeller of rotor part 4 and runner centering, and anti-drive end adopts sleeve bearing 3 to support, the radial force of sleeve bearing 3 bear rotor parts 4, drive end adopts bearing part 8 to support, and bearing part 8 is the axial force of bear rotor parts 4 both, again bearing radial force, wash tub pipe parts 6 insert two ends with the press water in the delivery chamber, be used to wash mechanical seal and sleeve bearing, end cap 2 connects with the pump housing 1 and pump cover 5, and it is sealed into the end face static seal.Rotor part 4 is driven the function that liquid is realized carrying in the back.

The utility model compact structure, the efficient height, easy to maintenance, can reduce water pump manufacture cost and operating cost, stable.

Claims (1)
