Description

Technical Field

[0001] The utility model belongs to the field of lift pumps, and specifically relates to a fixed installation structure of a liquid lift pump Background Art

[0002] A liquid lifting pump is a pump product that integrates a pump, a pump machine, a housing, and a control system. It can be used to lift various liquids in industrial production, such as the tank liquid of a steel wire surface treatment production line and the treatment liquid on a Zn or Cu plating production line. It can work on the ground or under the liquid. The present application relates to a liquid lifting pump that works on the ground. The body of the liquid lifting pump is installed on an equipment platform on the liquid surface for easy repair and maintenance. The long shaft, impeller, and casing extend below the liquid surface. Under the action of the impeller, the liquid is lifted and extracted along the casing.

[0003] The liquid lift pump installed on the equipment platform has a long major axis, so a small vibration will cause the shaft head to jump. Therefore, the fixed installation method of the liquid lift pump needs to be improved to reduce vibration.

[0004] In addition, the liquid lift pump needs to work for a long time, so it is easy to heat up and the temperature rises, especially at the root of the long shaft above the liquid surface. The heat generated by the rotational friction is easy to accumulate between the pump and the pump seat. If the heat cannot be dissipated for a long time, the liquid lift pump may be damaged easily.

When the pump seat body is connected to the mounting seat, the liquid lifting pump can be installed on the equipment platform. The specific connection form is as follows:

[0007] The U-shaped connecting member is integrally formed by a first connecting plate, a side plate and a second connecting plate, the first connecting plate and the second connecting plate are arranged opposite to each other, and bolt through holes are respectively provided on the first connecting plate and the second connecting plate;

[0008] The side of the pump seat body is provided with a plurality of heat dissipation slots, and the heat between the pump and the pump seat can be dissipated to the outside through the heat dissipation slots. The inner side of the heat dissipation slots is also provided with bolt through holes.

[0009] When the mounting base is fitted with the end face of the pump base body, the first connecting plate of the U-shaped connecting piece is located in the heat dissipation slot, and the second connecting plate is fitted with the outer end face of the mounting base. The bolts are sequentially passed through the bolt holes of the first connecting plate, the bolt holes of the heat dissipation slot, and the bolt holes of the second connecting plate and are then tightened by nuts. In this way, the pump base body and the mounting base can be conveniently fastened and connected, and the two connecting plates of the U-shaped connecting piece can firmly clamp the pump base body and the mounting base, making the connection between the pump base body and the mounting base more stable and reliable, ensuring the stability of the liquid lifting pump during operation to reduce vibration.

[0010] Preferably, four heat dissipation slots are evenly distributed on the side of the pump seat body, and each heat dissipation slot corresponds to a U-shaped connector, a bolt and a nut; this makes the pump seat body have a better heat dissipation effect, and the fixed connection between the pump seat body and the mounting seat is more stable and reliable.

[0011] Furthermore, a convex ring body is integrally connected to the end face of the pump seat body, and the mounting seat is provided with an annular step platform on the end face that fits with the pump seat body. The convex ring body cooperates with the annular step platform, and the convex ring body can be placed on the step of the annular step platform. The design of the convex ring body and the annular step platform facilitates the docking of the pump seat body and the mounting seat, making the connection and installation more convenient, and can also play a limiting role, so that the pump seat body will not be offset after docking with the mounting seat.

[0012] Preferably, the nut and the bolt are connected in a double-nut manner, which can prevent the nut from loosening under vibration.

[0013] Preferably, the pump seat body is integrally injection molded, and the U-shaped connecting piece is an elastic aluminum profile.

[0014] Through the above technical solution, the utility model at least includes the following beneficial effects:

[0015] In the technical solution of the present application, the heat dissipation slots on the pump seat body not only provide heat dissipation between the pump machine and the pump seat, but also provide an installation position for the U-shaped connector, thereby killing two birds with one stone. The U-shaped connector can firmly clamp the pump seat body and the mounting seat, and can conveniently and securely connect the pump seat body and the mounting seat. The fixed installation structure is stable and reliable, and can ensure the stability of the liquid lifting pump during operation, so as to reduce vibration and avoid shaft head bounce.
