Abstract

The utility model relates to multifunctional electric immersible pump, which is available both on a land operation surface and on an underwater operation surface. The utility model overcomes the defects of the existing submersible pumps that the existing submersible pumps requires critical use conditions and can only work when placed vertically under water, and that the electric motor part can not run without water which leads to that the water on operation layer can not be drained. The utility model is composed of a pump body, a main body, an electric motor, a water collecting segment, which are connected with each other, etc. The multifunctional electric immersible pump adopts a down draft and up drainage mode, a self-cooling method, a centrifugal double volutes and a combined seal structure, and an electric motor protector is installed on the multifunctional electric immersible pump, which has the function of automatic protection to overloading, short circuit, phase lacking and sealing failure. The utility model which has the advantages of small size and low running noise can work either on land or underwater and can drain the water in an operation layer, the bin bottom of a ship and other containers.

Description

Multifunctional electric immersible pump

The utility model belongs to all spendable multifunctional diving electric pump of underwater operation face on the water.

Existing submersible pump, the submersible pump of several models such as QY, Q, QX and QS of producing as Renmin Motor Factory, Shanghai, water pump works, Hangzhou etc., and the external submersible pump of producing, can only in water, work by vertically-arranged, service condition is required harsh, the running of can not dewatering of motor part, the water of the outer portion of motor cools off by transmission of heat, and rate of cooling is slow, in case dehydration will be burnt motor; Cause work layer water not drain.Motor has interior protection or has only outside distance protection, poor effect, and it is unreliable to protect.Motor seal adopts the individual layer sealing, in case seal failure will cause the motor water inlet and burn.Adopt centrifugal guide vane, volume is heavy, and external dimension are big, complex process.

The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of using scope wide, can realize that motor is self cooling, not only can horizontally-arranged, tilting operation, but and the multifunctional diving electric pump of operation at sea.

The row of sucting, self cooling, centrifugal pair volute casing and compound sealing structure under the utility model is achieved in that and adopts, and random installation motor protecter are protected automatically to overload, short circuit, phase shortage and the seal failure of motor.

The utility model has the advantages that:

The self cooling structure of the row of sucting under a, the employing, promptly the pressure flow of pumping with itself is by the runner of main body, motor, bearing, Sealing and other heat that turns round the part generation to inside in flowing are taken away fast by high speed pressure, reach automatic cooling, it is all worked under lower temperature, thereby improved the working life and the task performance of component; And waterbornely all can work under water, can with at the bottom of work layer, the boats and ships storehouse and the water in other container drain.

The utility model also can be used as general centrifugal pump, sprinkling pump, flushingpump, fire water pump, pipeline mounted pump and high-floor feedwater pump and uses.

B, employing rubber corrugated pipe type double mechanical seal, motor protecter is installed in the space of water collection section, can protect automatically motor, thereby increase the service life, and power consumpiton is few, does not need frequent maintenance.

C, the pump housing 7 adopts centrifugal pair of volute casing structure, makes the radial force of impeller 6 can autobalance, thereby improved the rigidity of axle, alleviates the load of axle and bearing, reduced wearing and tearing, reduced noise.
