Abstract
The utility model relates to a water pump driven by a flexible shaft, which is especially suitable for ponded water drain on the construction site and ponded water and sewage drain in underground pipelines of residential houses and industrial and mining establishments. The main structure comprises a pump body, the flexible shaft and a motor. The pump body is separate from the motor, and a drive shaft adopts the flexible shaft. The pump body is provided with a pump casing. The front end of the pump casing is provided with a pump cover, the rear part is provided with a thread cover and the side is provided with a water outlet pipe. The pump shaft is arranged in a thread sleeve and an outer sleeve pipe, the front end of the pump is provided with an impeller, and the middle part is provided with a bearing and a sealing ring. The pump has simple structure, low cost, small size, light weight, easy assembly and disassembly, convenient maintenance and long service life.
Description
The utility model relates to a kind of water pump that adopts the flexible axle transmission.Be specially adapted to building site ponding and get rid of, residential houses, industrial and mining enterprise's under ground piping, ponding, sewage are got rid of.
The submersible pump commonly used that drains the water away is repaired because Environmental Conditions is poor in building site, job site, residential houses at present, and it is many to contain silt impurity in the sewage.Enter easily and cause impeller stuck in the pump, submerge when submersible pump uses in addition, sewage, have corrosive water capacity and easily enter pump housing motor seal and partly cause the motor short circuit to burn out motor, and use place ponding to be not easy to take out most influence construction.Centrifugal pump, sewage pump require to be fixedly mounted on big, the mobile inconvenience of a correct position bulking value, centrifugal pump uses water quality requirement clean, and the fewer local bad use of the water yield.Submersible pump, centrifugal pump, sewage pump complex structure, the cost height.
The purpose of this utility model provides a kind of flexible shaft water pump and adopts the pump housing and motor separation structure form, in the submersible entry of the pump housing motor by shaft drive, simple in structure, easy to maintenance, long service life.
Flexible shaft water pump takes following mode to realize, flexible shaft water pump mainly is made up of the pump housing, flexible axle, motor, and the pump housing separates with motor, and transmission shaft adopts flexible axle.The pump housing mainly is made of pump case pump shaft, impeller, thread bush, outer sleeve, bearing, seal ring.The pump case front end is equipped with and is processed with into water aperture on pump cover, the pump cover, plays retaining silt particle, foreign material effect.Threaded cap is equipped with at the pump case rear portion, threaded cap adopts screw thread to link to each other with thread bush, and impeller is housed in the pump case, and the water outlet pipe is equipped with in the pump case side.Pump shaft is assemblied in thread bush and the outer sleeve, and the pump shaft front end is equipped with impeller, middle part and bearing, seal ring, pump shaft rear end are housed are processed with screw thread, can link to each other with flexible shaft end.Flexible axle one end is equipped with flexible shaft end, is threaded, and can link to each other with pump shaft, and the other end links to each other with motor shaft, and sleeve pipe is equipped with in the flexible axle outside.
Flexible shaft water pump is because the pump housing, flexible axle, motor can separate, and the pump housing is put into water during installation, and pump housing impeller adopts the vane type oil pump leaf, does not require sealing, and motor can be placed the smooth working location, is connected by flexible axle, because motor is away from water, motor is not fragile.Flexible shaft water pump is simple in structure, cost is low, volume is little, in light weight, that mounting or dismounting are installed is easy, easy to maintenance, long service life.Flexible shaft water pump can be used for building site ponding eliminating, residential houses, industrial and mining enterprise's under ground piping ponding, sewage eliminating, water quality inferiority, impurity is many, volume is little tunnel draining, particularly use the building site, can with vibrator motor, flexible axle, the supporting use easy accessibility of flexible pipe.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is a flexible shaft water pump pump body structure schematic representation.
Fig. 2 is that flexible shaft water pump pump housing A is to schematic representation.
Fig. 3 is a flexible shaft water pump motor flexible axle structural representation.
Constitute by the pump housing, flexible axle (16), motor (18) three parts with reference to accompanying drawing, flexible shaft water pump.The front portion of the pump housing is that pump case (3), rear portion are that thread bush (8), outer sleeve (11), pump shaft (13) are contained in thread bush, in the outer sleeve, the pump shaft front end is equipped with impeller (2) and adopts nut (4) and locking pad (5) to be fixed on the pump shaft front end, and impeller (2) is the vane type oil pump leaf.Copper sheathing (7) is housed between pump shaft and the thread bush (8), the pump shaft middle part is equipped with and between bearing (10), the bearing lining (14) is housed, bearing two ends are equipped with seal ring (9), (12), seal ring can adopt the square RunddichtringO, can waterproof, dust protection enters bearing.It is water intake that pump case (3) front end is equipped with pump cover (1), and water outlet pipe (15) is equipped with in the pump case side, and threaded cap (6) is equipped with in the pump case rear end, and threaded cap adopts screw thread to link to each other with thread bush (8).Flexible axle (16) one ends have when flexible shaft end (17) uses and can be connected with pump shaft (13) rear end screw thread, and flexible axle (16) the other end is connected with motor (18) axle.Motor can adopt JO
2Threephase asynchronous drives, motor put steady after, water pump body is placed on that the starting electrical machinery switch just can pump drainage water in the water.
Claims (3)
1, a kind of flexible shaft water pump with the pump housing, pump case, impeller, pump shaft, motor, it is characterized in that the pump housing separates with motor, transmission shaft adopts flexible axle, the pump case front end is equipped with pump cover, and threaded cap is equipped with at the pump case rear portion, and threaded cap links to each other with thread bush, pump shaft is assemblied in thread bush and the outer sleeve, the pump shaft front end is equipped with impeller, and bearing is equipped with at the middle part, seal ring; The pump shaft rear end is processed with screw thread, and flexible axle one end is equipped with flexible shaft end, can link to each other with pump shaft, and the other end links to each other with motor shaft.
