Abstract
The utility model relates to a multipurpose water pump which is provided with a shell body 1. A motor part composed of a stator coil 2, a rotor 3 and a shaft 4 is arranged in the shell body 1. The utility model is characterized in that the shell body 1 is provided with a water inlet 5, one layer of filter screen 6 is arranged in the water inlet 5 and a check valve 7 is arranged between the water inlet and the inner cavity body of the shell body. The upper end of the shell body 1 is connected with a pump body 8 and a pump cover 11. A group of water pump impellers 9 fixed to the top end of the shaft 4 is arranged in the pump body and the pump cover. The utility model has the advantages that the motor and the cavity body of the water pump are communicated with each other, the motor can work in the water and the utility model can be used as a submersible pump or a centrifugal water pump.
Description
The utility model relates to water pump, further is to belong to the Centrifugal water pump that serves many purposes.
The Centrifugal water pump of prior art is made submersible pump and is used, can only below the water surface, use, and anhydrous operation on the ground, then can only dry type air-cooled when making centrifugal pump and using on the ground, can not immerse in the water and move.Even in large open well, use, also, burn faults such as motor often because reasons such as humidity cause electric leakage.
Deficiency based on prior art exists has proposed the purpose of this utility model, and the purpose of this utility model is in order to overcome the deficiency that above-mentioned prior art exists, to design a kind of multipurpose water pump.
The purpose of this utility model realizes according to structure described below, this multipurpose water pump, it has housing 1, in housing 1, has stator coil 2, rotor 3 and axle 4 are formed motor portion, it is characterized in that a water intake 5 is arranged on housing 1, and safety check 7 is in addition arranged in this water intake 5 between the internal cavity of one deck filter screen 6 water intakes and housing, the upper end of housing 1 connects a pump housing 8 and pump cover 11, and the inside of the pump housing and pump cover is the one group of water pump vane 9 that is fixed on axle 4 upper ends.The mutual UNICOM of cavity of motor part and water pump part.The multipurpose water pump of this structure both can be in water also can be in ground handling, and its performance is not exerted an influence.
The utility model has the advantages that the motor portion in the housing 1 is worked in water, owing to adopted waterproofing design, accident such as can overcome electric leakage that motor with air cooling causes owing to reason such as make moist, burn.Water intake adopts filter structure, has prevented that effectively impurity such as silt from entering, and safety check can pour into diversion effectively.Therefore, this pump is fit to present most of occasion to be used, and the many usefulness of a pump have reached the purpose of this utility model fully.
Description of drawings, accompanying drawing are topology views of the present utility model, and each sequence number in the accompanying drawings is: 1, housing, 2, coil, 3, rotor, 4, axle, 5, water intake, 6, filter screen, 7, safety check, 8, the pump housing, 9, impeller, 10, outlet pipe, 11, pump cover, 12, cable, 13 motor cover.
Describe structure of the present utility model in detail below in conjunction with the specific embodiment in the accompanying drawing, with reference to accompanying drawing, this water pump mainly has housing 1, has stator coil 2 in housing 1, the motor portion that rotor 3 and axle 4 are formed.It is characterized in that a water intake 5 is arranged on housing 1, in this water intake 5 one deck filter screen 6 is arranged, this filter screen adopts the copper filter screen of 40 orders can satisfy the needs of general use.Also have a safety check 7 between the internal cavity of water intake and housing, this valve can pour into diversion easily in water pump before water pump uses, so that start water pump smoothly.The upper end of housing 1 connects a pump housing 8 and pump cover 11, and pump cover top is outlet pipe 10.The inside of the pump housing and pump cover is the one group of water pump vane 9 that is fixed on axle 4 upper ends.Impeller can design one or more impellers according to the needs that use, and two impellers have been shown in the accompanying drawing.The lower end of housing 1 is a motor cover, also is the base of pump simultaneously.Cable 12 is drawn from lower part of frame.The cavity of the motor portion of housing 1 and water pump part communicates with one another, and motor section is divided through water-proofing treating, and during work, motor is all the time in water.When doing the centrifugal pump use, 5 places connect suction sleeve with water intake, from outlet pipe 10 perfusion diversions, can connect power supply after filling with, the operation of drawing water.The part that the motor feels hot sheds through the water arrival housing of enclosure interior, and another part heat is discharged outside the pump housing through impeller and water channel with flowing water, thereby has guaranteed heat radiation better in the working procedure.When making submersible pump and using, the whole pump housing and motor all place water, with common submersible pump work, the heating of motor in the water of enclosure interior and housing import water outside the pump housing into, distribute heat.
