Water pump structure

Technical Field

The utility model relates to a water pump technical field, in particular to water pump structure.

Background

The water pump is a machine for conveying liquid or pressurizing liquid, and it can transfer the mechanical energy of prime mover or other external energy to the liquid to increase the energy of liquid, and is mainly used for conveying liquid including water, oil, acid-base liquid, emulsion, suspoemulsion, liquid metal, etc., and can also convey liquid, gas mixture and liquid containing suspended solid matter.

The pump body and the pump cover of current water pump are generally fixed through bolted connection, set up the connecting hole on the outside of pump case and pump cover, the bolt passes the connecting hole and screws up fixedly, this kind of connected mode installation is inconvenient, the tightness that the elasticity degree difference when a plurality of bolt installations can lead to the pump body and pump case to be connected is compactedness, simultaneously because the bolt exposes in the pump body outside, because the special operational environment of water pump, the easy corrosion of bolt leads to connecting the condition that the pine takes off or rust death can't be opened after long-time practicality easily, there are some not enough.

Therefore, how to change the connection mode of the pump body and the pump shell to replace the existing bolt connection and avoid the situation that the connection is loosened or rusted and can not be opened easily in the bolt connection are technical problems to be solved urgently in the industry.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a water pump structure aims at changing the connected mode of the pump body and pump case, replaces current bolted connection, avoids the easy connection pine that appears of bolted connection to take off or the condition that the rust can't be opened.

The utility model provides a water pump structure, including a cylindric pump case and a pump cover, it is provided with first screw thread to surround on the outer wall of pump case front end, the rear end of pump cover inner wall encircle be provided with the second screw thread of the mutual meshing of first screw thread, the second screw thread with second screw thread adaptation meshing will the pump case with the pump cover is connected fixedly.

Preferably, the inner cavity of the pump shell is provided with a motor, and the bottom of the inner cavity of the pump shell is provided with a pouring sealant for sealing.

Preferably, the front end of the motor extends to the outside of the inner cavity of the pump shell, and a sealing ring is arranged at the contact position of the front end of the motor and the inner wall of the pump cover.

Preferably, the pump cover is provided with a water inlet and a water outlet.

Preferably, a ring of raised locating ring is formed on the outer wall of the pump casing at the rear end of the first thread.

The utility model discloses set up the screw thread on pump case and pump cover respectively, stretch into pump cover inner chamber with the pump case front end during the installation, rotate and screw up, the mutual chucking of screw thread through the looks adaptation is fixed with pump case and pump cover connection, replace current bolted connection, it is not good to avoid the different compactness that leads to connecting of bolt tightening degree, avoid the bolt corrosion to lead to connecting the condition that the pine takes off or rust death leads to unable opening simultaneously, the structure is simpler, the dismouting is more convenient, it is better to connect the compactness.

Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-4, an embodiment of the present invention is provided, which is a water pump structure, including a cylindrical pump case 1 and a pump cover 2, the inner cavity of the pump case 1 is provided with a motor 6, the bottom of the inner cavity of the pump case 1 is provided with a pouring sealant 7 for sealing, and the pouring sealant 7 fixes and seals the bottom of the motor 6. The opening end of the pump shell 1 is the front end, and the sealing end is the rear end. The opening end of the pump cover 2 connected with the pump shell 1 is the rear end, and the sealing end is the front end.

The outer wall surface of the front end of the pump shell 1 is provided with first threads 3 in an encircling mode, the rear end of the inner wall of the pump cover 2 is provided with second threads 4 which are meshed with the first threads 3 in an encircling mode, and the pump shell 1 and the pump cover 2 are fixedly connected through the second threads 3 and the second threads 4 in a matching and meshing mode.

During the installation, the front end of pump case 1 stretches into in the rear end of pump cover 2, corresponds first screw thread 3 and second screw thread 4, rotates to screw up for pump case 1 screws up the inside of fixing to pump cover 2, realizes being connected fixedly with pump cover 2. Replace current bolted connection, avoid the bolt tightening degree difference to lead to the compactness of connecting not good, avoid the bolt corrosion to lead to connecting the condition that the pine takes off or rust death leads to unable opening simultaneously, the structure is simpler, and the dismouting is more convenient, connects the compactness better.

The front end of the motor 6 extends to the outside of the inner cavity of the pump shell 1, and a sealing ring 5 is arranged at the contact position of the front end of the motor 6 and the inner wall of the pump cover 2. The inner cavity of the pump cover 2 is sealed with the inner cavity of the pump shell 1, so that the damage of water entering the motor 6 caused by the fact that water flows into the shell 1 from the outer side of the motor 6 along the inner wall of the pump shell 1 is avoided.

The pump cover 1 is provided with a water inlet 8 and a water outlet 9, and the water inlet 8 and the water outlet 9 are respectively arranged in two opposite directions.

A raised locating ring 10 is formed on the outer wall of the pump housing 1 at the rear end of the first thread 3. After the installation is accomplished, the rear end edge of pump cover 2 hugs closely on the preceding terminal surface of holding ring 10 for the pump cover 2 is inseparabler with the junction of pump case 1, can reduce water, impurity etc. and get into the threaded connection department of pump cover 2 and pump case 1 and cause the damage to the screw thread.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structural changes made by the contents of the specification and the drawings, or the direct or indirect application in other related technical fields, are included in the same way in the protection scope of the present invention.
