Description

Amphibious pipeline pump
Technical field
The present invention relates to pipeline pump, specially a kind of amphibious pipeline pump.
Background technology
The water inlet and delivery port of pipeline pump are point-blank, to be transported so being easily series in hydraulic pipeline OK.It is widely used in building water supply, heating boiler periodical feeding;It can also be used for other water supply and sewage places.
Existing pipeline pump(As shown in Figure 1)It is made up of the pump housing, water wheels, linkage section and common dry type motor;Linkage section by The brace rod being spaced apart between the adpting flange and both ends adpting flange at both ends is formed;The connection method that linkage section passes through its both ends Orchid is connected with motor and the pump housing respectively;Water wheels are located in the pump housing and are fixed on the shaft end of motor.Due to using common dry type Motor, therefore, existing pipeline pump when because pipe leakage or it is damaged flooded when, or will be unable to work under water.Further, since The cooling fan, bearing, rotor etc. of common dry type motor is exposed to working space, and noise is larger during work.
The content of the invention
The present invention solves the problems, such as that existing pipeline pump can not be amphibious, there is provided a kind of amphibious pipeline pump.
The present invention adopts the following technical scheme that realization:Amphibious pipeline pump, including the pump with entery and delivery port Body, water wheels and the submersible motor with water jacket;Submersible motor with water jacket includes motor, sealing shroud loaded on the water jacket on motor With the connecting seat for being connected to motor power output end, water jacket inner chamber is formed between water jacket and outer surface of motor, connecting seat passes through method It is blue to be tightly connected with the pump housing, top cover labyrinth is provided with connecting seat, top cover labyrinth is sealingly fastened on the bottom end cover of motor, motor Output shaft passes through top cover labyrinth, and middle closure is provided with connecting seat, and the surrounding of middle closure and the inner wall sealing of connecting seat connect, The output shaft of motor passes through middle closure, and the Double End machine being placed on motor output shaft is pressed between top cover labyrinth and middle closure Tool seals;The lower sealing cover being provided with connecting seat below middle closure, surrounding and the connecting seat inner wall sealing of lower sealing cover Connection, the output shaft of motor passes through lower sealing cover, pressed between lower sealing cover and water wheels to have the list being placed on motor output shaft End surface mechanical sealing, further to increase motor power output end sealing property;Water jacket inner chamber is provided with inlet opening and backwater hole, water The inlet opening of inner chamber is covered axially also cross the adpting flange of connecting seat, the adpting flange of motor bottom end cover and electric machine stand lower end Adpting flange, and realize with the insertion of water jacket inner chamber, be provided with the opening position that the side wall of connecting seat is located at below lower sealing cover Apopore, the apopore connect through water pipe or pipeline with the inlet opening of water jacket inner chamber;The backwater hole of water jacket inner chamber is opened in motor On the adpting flange convex edge of support lower end, water inlet one end of the pump housing, the return port communicated with the water inlet of the pump housing, water jacket are provided with Return port on the backwater hole and the pump housing of inner chamber is linked up with return pipe;Pump seal ring, pump seal ring are provided with below lower sealing cover Pressure sealed around be fixed between connecting seat lower end adpting flange and the pump housing, the annular distance of pump seal ring is placed on the top mandrel of water wheels Partial outer ring, and keep gap(Gap is kept between the top arbor portions of the annular distance of pump seal ring and water wheels);Connection It is provided with what the space respectively between the space between top cover labyrinth and middle closure, middle closure and lower sealing cover communicated on seat Oil filler point, be screwed with oil fill plug on oil filler point, made respectively by oil fill plug space between top cover labyrinth and middle closure, in Space abundance lubricating oil between closure and lower sealing cover.During work, current enter the pump housing from the water inlet of the pump housing, through water wheels After supercharging, flowed out from the delivery port of the pump housing, meanwhile, water flows through apopore on connecting seat, the inlet opening of water jacket inner chamber enters water Inner chamber is covered, then the backwater hole through water jacket inner chamber, return pipe are returned in the water inlet of the pump housing, realize the circulation of cooling water, it is complete The cooling of paired submersible motor.
Having in existing product includes the pipeline pump of the pump housing, water wheels and dry type motor, and including the pump housing, water wheels and with water The immersible pump of the submersible motor of set.The dry type motor of existing pipeline pump is substituted for the submersible motor with water jacket of immersible pump, should Pipeline pump determines it due to the inlet opening of water jacket inner chamber, the position of backwater hole and structure of its submersible motor with water jacket It can be used under water, and be not used to land;The present invention by improving the inlet opening of water jacket inner chamber and the position of backwater hole and structure, Realize the amphibian purpose of pipeline pump.What the present invention was formed between the top cover labyrinth and middle closure in cartridge type connecting seat Annular seal space is provided with double mechanical seal, thus form first oil chamber;In lower sealing cover and water wheels Lun Valley and pump Single mechanical end face seal is provided between sealing ring, is thus formd between the middle closure in connecting seat and lower sealing cover Two oil chambers, this just adds an oil chamber than traditional submersible motor with water jacket, is two sets of mechanical seals Pair of friction components lubrication provides favourable lubricating condition, improves the service life of twice mechanical seal, and then improve the present invention The sealing life of the pipeline pump;Space between lower sealing cover and water wheels is separated into two parts, pump seal ring by pump seal ring Upper space through the water jacket inner chamber pump housing water inlet relatively low with pressure due to communicating, and the lower space of pump seal ring is full of water wheels The water under high pressure thrown away, therefore, the pressure of pump seal ring upper space are significantly lower than the pressure of pump seal ring lower space, in this way, Compared to pump seal ring is not provided with, the power axially downwards suffered by motor output shaft can be reduced, so as to improve the bearing longevity of the pipeline pump Life;The seal pressure of single mechanical end face seal is reduced simultaneously, improves sealing life, and then improves the use longevity of pipeline pump Life.As a result of the submersible motor with water jacket, the cooling fan on original dry type motor, and bearing, rotor etc. are eliminated Rotation vibration component is enclosed among water jacket, reduces the operation noise of pipeline pump.
The present invention is reasonable in design, unique, can both be run on land in conventional environment;Can also be pulled the plug fortune OK.
