Abstract
The utility model relates to a removable multi-stage pump, comprising pump body, middle section, impeller, guide vane, impeller baffle, outer cylinder, motor, middle section of water outlet and water pump shaft. The pump also includes first half the coupling, latter half of the coupling, sealing seat, mechanical sealing, motor support, lower gland, bearing bush and through hole of pump body; through improvement, dynamic pressure flow is formed between the pump shaft and the bearing bush, wearing is reduced and service life of spare parts is lengthened, and also maintenance and repairing can be done conveniently. The pump has simple structure and is safe and reliable in operation.
Description
Technical field
The utility model relates to a kind of water pump, particularly relates to the multistage water pump of a kind of detachable type.
Background technique
Multistage water pump is widely used in the supporting water system of tall building, deep-well and fire-fighting, multistage water pump often needs repairing in the prior art, there are two places at the position of rapid wear, the one, the seal ring on the water pump spindle lost efficacy and caused leakage, the 2nd, the water pump shaft extension supporting base of soaking in water damages because of wearing and tearing make whole water pump.
Summary of the invention
The purpose of this utility model provides the multistage water pump of a kind of detachable type, by improving, can not change seal ring under the situation with motor and water pump decomposition, and is being provided with axial flow dynamically lubricating mode, to remedy the deficiencies in the prior art.
The utility model is realized as follows: the multistage water pump of detachable type, it includes the pump housing, stage casing, impeller, stator, impeller interstage sleeve, outer cylinder body, motor, water outlet stage casing, water pump spindle, and it also includes before the coupling half, coupling is later half, sealing seat, mechanical seal, motor frame, lower cover, bearing shell, pump housing through hole;
Described motor frame upper end fixes with motor flange, motor frame lower end is connected with water pump by turnbuckle, on motor frame circular arc external surface, be provided with service hatch, be provided with sealing seat and mechanical seal in the motor frame, sealing seat is fitted in the mechanical seal, and by screw in motor frame bottom, water pump spindle is by passing in sealing seat and the mechanical seal, leave the shaft extension space between the motor shaft on the same center line and two relative shaft extension ends of water pump spindle, the half-sum coupling is later half before by coupling is connected for two shaft extensions.
Be provided with bearing shell in the described lower cover, the other end of water pump spindle is inserted in the bearing shell, and the arc-shaped surface in the lower cover bottom is provided with the through hole that communicates with lower cover inside, links to each other by pump housing through hole and water pump are inner.
The arc-shaped surface of described lower cover bottom is provided with 2-4 through hole.
Describedly on motor frame circular arc external surface, be provided with 2 service hatches.
When work, lower cover is immersed in the water channel, the gap of sub-fraction current through between water pump spindle and bearing shell, suck in the water pump by through hole and pump housing through hole, make the cooling that forms dynamic pressure stream between water pump spindle and bearing shell with lubricated, reduced wearing and tearing, prolonged the working life of part in addition; When safeguard changing easily damaged parts mechanical seal, the half-sum coupling is later half before with coupling unloads by service hatch, pulls down sealing seat, changes via taking out in the shaft extension space of two relative shaft extension ends of motor shaft and water pump spindle.
The multistage water pump good effect of the utility model detachable type is: by improving, makes the multistage water pump of detachable type not only prolong working life, and made things convenient for maintenance and repair, and simple in structure, safe and reliable.
