[0033] The pump head assembly 4 includes a self-priming pump head 42 connected to the pump casing 3 via a third mounting base 41. The self-priming pump head 42 has built-in components such as an impeller for pumping and conveying fluid. One end of the self-priming pump head 42 is connected to a water suction connector 43 for receiving the fluid to be conveyed, and the other end is connected to a drain connector 44 for discharging the conveyed fluid, ensuring the integrity of the fluid conveying process.

[0034] Positioning components 12 are symmetrically distributed on both sides of the base 11, which can limit the installation of the equipment from both sides and improve the installation accuracy. The bottom of the support foot 13 is fixedly connected with an anti-slip pad. The anti-slip pad is made of rubber, which has good anti-slip and shock absorption properties, which can further enhance the stability of the equipment placed on the ground or other foundations and reduce the displacement caused by vibration during the operation of the equipment.

[0035] The first mounting base 21 and the support platform 14 are fastened together by bolts, which is reliable and easy to disassemble and assemble. The upper surface of the first mounting base 21 is provided with a shock-absorbing buffer layer. The shock-absorbing buffer layer is made of elastic rubber material, which can effectively absorb the vibration generated by the operation of the motor 22, prevent the vibration from being transmitted to components such as the base 11, improve the operating stability of the power assembly 2, and also reduce the impact of vibration on other components of the equipment.

[0036] The protective housing 24 is made of stainless steel and has an anti-corrosion coating on its surface. Stainless steel is strong and corrosion resistant.

[0037] A leveling shim is provided between the second mounting base 31 and the support base 15. The leveling shim is made of metal and its thickness can be selected according to the installation requirements. By adding or removing the leveling shim, the levelness of the pump casing installation can be adjusted to ensure the operational stability of the pump casing 3 and its internal components, and to avoid abnormal wear and poor operation caused by uneven installation.

[0038] The internal impeller of the self-priming pump head 42 is made of high-chromium cast iron. High-chromium cast iron has high hardness and good wear resistance, which can improve the service life of the impeller and reduce problems such as the decrease in self-priming efficiency caused by impeller wear. The impeller blades have an arc-shaped structure, with 3-6 blades. The arc-shaped blades conform to the principles of fluid mechanics and can improve the efficiency of fluid suction and transportation. The reasonable number of blades can reduce operating energy consumption while ensuring self-priming performance.

The rubber sealing gaskets have good sealing performance and can effectively prevent fluid leakage at the interface, ensuring the sealing and reliability of the equipment operation.

[0040] The connections between the mounting components 1, power components 2, pump housing 3, and pump head components 4 are all secured with anti-loosening bolts and anti-loosening washers. The anti-loosening bolts have anti-slip threads on their surfaces. The anti-loosening bolts and anti-loosening washers work together to effectively prevent the bolts from loosening due to vibration during equipment operation, ensuring the stability of the connections between the components. The anti-slip threads further enhance the anti-loosening effect of the bolt connections.

[0041] The working principle of this utility model is as follows: When the motor 22 starts, the power is transmitted to the connecting shaft 32 inside the pump casing 3 through the coupling 25 and the coupling assembly 26. The connecting shaft 32 drives the impeller inside the self-priming pump head 42 to rotate. The rotation of the impeller generates centrifugal force and other effects, which causes the self-priming pump head 42 to draw fluid through the suction connector 43 and then discharge the fluid through the drain connector 44, thus realizing fluid transportation. The installation assembly 1 ensures the stable installation of the equipment through the positioning part 12, the support foot 13, etc. The protective shell 24 and the shock-absorbing buffer layer of the power assembly 2 improve the stability of power transmission. The high wear-resistant impeller and sealing structure of the pump head assembly 4 ensure self-priming, transportation performance and sealing performance.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
