Technical field
The utility model relates to a kind of submersible pump, is meant a kind of submersible pump that is applicable to suction clear water such as river, lake, the pool especially.
Background technique
All kinds of submersible pumps of manufacturer's manufacturing in the past, the motor that is complementary that most of and professional electrical machinery plant produces carries out supporting, because the pump housing and motor respectively establish one's own system, when supporting use, often bring inconvenience to installation, influence the operation stability of submersible pump because of size disunity or architectural difference.For this reason, producer improves submersible pump in the past, as the patent No. be: 95220631.5, the mandate publication number is: CN2259512, a kind of electromechanical integration clean waterpump is disclosed, it is made up of motor, the pump housing and impeller, and the front cover alloying of its middle pump body and motor is an one, and impeller is installed on the endoceliac motor shaft of pump.Though the clear water submersible pump of this structure has solved the structural type of the pump housing and motor split assembling effectively, the difficulty of also having brought the pump housing to make thus, particularly pump housing sand molding difficulty is bigger, thereby reject rate is higher, thereby has increased cost of production.
In addition, cause working efficiency to reduce for the heating that reduces motor shaft black box position, generally the black box position is arranged on high hydraulic pressure end in the pump housing, so that utilize formed internal water to circulate the coolant seal assembly.Yet, when this submersible pump is used to extract water, the water that more particularly contains the part suspended particulate, this submersible pump can there are the following problems: the grit of black box in water impact and friction under be easy to wearing and tearing, in case the black box wearing and tearing are leaked, leaking of producing can enter motor internal and burn out motor windings, makes the submersible pump premature failure.Black box between submersible pump parts and the motor component is the key of submersible pump, and the sealing effect of black box will directly influence the reliability and the working life of motor.
Summary of the invention
The utility model provides a kind of simple and reasonable for structure in order to solve the deficiency that above-mentioned prior art exists, and makes easy processing, good seal performance, and cooling effect is superior, the clear water submersible pump of long service life.
For achieving the above object, the utility model adopts following scheme: a kind of submersible pump, include motor, the pump housing, be positioned at pump housing chamber and by the black box of shaft-driven impeller of motor and motor shaft, be fixedly connected with oil cylinder between the described pump housing and the motor, it is made of cylinder body and cylinder cap, it is indoor that the black box of motor shaft is installed in the sealing oil that cylinder body and cylinder cap form, and the indoor machinery oil that is perfused with of sealing oil.
The utility model further is set to: described motor shaft black box adopts the double seals structure, and it is set on the motor shaft, and two ends are inlaid in respectively in the groove of offering on cylinder body and the cylinder cap.
The Oil sealing assembly of oil cylinder is installed on the end face of the described cylinder cap outside.
Described being positioned on the pump housing inlet end is fixedly connected with base, is equipped with window of receiving water on the circumferential surface of base.
The beneficial effects of the utility model are: the utility model is compared with original technology, by between the pump housing and motor, having added an oil cylinder, this oil cylinder both can replace the front cover of original motor, played the interconnect function between the motor and the pump housing again, simplified the problem that the former submersible pump pump housing and motor front cover integrally casting are brought, and reduced cost of production widely, give and make, install and all bring great convenience.In addition, the black box of motor shaft is arranged in the oil cylinder, and employing double seals structure, and Oil sealing assembly is set on cylinder cap, utilize in-oil cylinder machinery oil that bearing, black box, motor are cooled off, good cooling results had both increased working life of bearing and black box, had improved the working efficiency of submersible pump; Guaranteed that again the hard particles in the sewage is difficult for black box is produced wearing and tearing, prevented that effectively liquid from permeating in motor cavity, guaranteed submersible pump normally safe operation for a long time, the working life of improving submersible pump.
Below in conjunction with embodiment and accompanying drawing the utility model is further specified.

Embodiment
As shown in Figure 1, the utility model embodiment adopts a kind of submersible pump, include the black box 12 of motor 1, the pump housing 2, impeller 21 and motor shaft 11, wherein motor 1 is made up of casing 13, cover 14, motor shaft 11 and the stator 15 and the rotors 16 that are arranged in the casing 13; Offer the water intake 22 and the water outlet 23 that are mutually 90 ° on the pump housing 2, be positioned on the pump housing 2 water intakes 22 ends and be fixedly connected with base 4, be evenly distributed with several window of receiving water 41 on the circumferential surface of base 4; Impeller 21 is arranged in the pump housing 2, and is connected on motor shaft 11 outboard ends.Be fixedly connected with oil cylinder 3 between the described pump housing 2 and the motor 1, wherein the cylinder body 31 of oil cylinder 3 is connected with motor 1, cylinder cap 32 is connected with the pump housing 2, the black box 12 of motor shaft 11 is installed in the sealing grease chamber 33 of cylinder body 31 and cylinder cap 32 compositions, sealing grease chamber 33 is by being perfused with machinery oil 34 in the oil inlet hole 35, and with bolt 36 sealings.
The utility model is embodiment further be set to, and described motor shaft 11 black boies 12 adopt the double seals structure, and it is set on the motor shaft 11, and two ends are inlaid in respectively in the groove of offering on cylinder body 31 and the cylinder cap 32 311,321.The Oil sealing assembly 37 of oil cylinder 3 is installed on described cylinder cap 32 outside end faces.
The utility model working principle: after the utility model is opened, motor shaft 11 impeller 21 are high speed rotary motion together, force pre-subpunch to be filled in impeller 21 interlobate liquid and follow the blade rotation, under the effect of inertial centrifugal force, liquid is done radial motion from impeller 21 centers to periphery.Liquid obtains energy in the movement process of impeller 21 of flowing through, static energy increases, and flow velocity increases.The liquid speed in the pump housing 2 that penetrates is slack-off gradually, and part is converted to the last drainage pipe that is connected on the water outlet 23 that tangentially flows into of static energy, and discharge tube flows out.When liquid gets rid of to periphery from impeller 21 centers, be formed centrally low pressure area in the impeller 21, under the effect of the total potential energy difference of storage tank liquid level and impeller 21 centers, cause liquid to flow in the pump housing 2 through water intake 22, rely on the continuous running of impeller 21, liquid just is inhaled into continuously and discharges.
