Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal pump assembly, in particular to an assembly platform for centrifugal pump production. Background Art

[0002] A centrifugal pump is a commonly used fluid machine that increases the kinetic energy of the fluid through a rotating impeller, thereby achieving fluid transportation. In a centrifugal pump, the fluid enters the impeller from the suction port and is thrown toward the pump casing as the impeller rotates, gaining energy in the process. After the centrifugal pump is produced, it usually requires manual assembly. The assembly workbench is specially designed for factory assembly, production, maintenance, operation, etc., and serves as an operating platform for various operations.

[0003] After searching, the document of announcement number "CN212635596U" mentioned that "the utility model relates to the technical field of slurry pump production, and discloses an assembly table for slurry pump production, including a bottom plate, a telescopic rod is fixedly installed on the top of the bottom plate, a supporting plate is fixedly installed on the top of the telescopic rod, a buffer is fixedly installed on the front of the supporting plate, a shock-absorbing component is fixedly installed on the top of the supporting plate, a workbench is fixedly installed on the top of the shock-absorbing component, a rotating shaft rod is movably installed inside the workbench, a side expansion board is fixedly installed on the outside of the rotating shaft rod, and a support rod is fixedly installed at the top center of the bottom plate. The assembly table for slurry pump production is fixedly installed at the top of the workbench. A rotating shaft rod is installed inside, and a side expansion plate is fixedly installed on the outside of the rotating shaft rod. When in use, the side expansion plate can be rotated by the rotating shaft rod and movably connected to the buffer member to expand the loading and use area of the workbench. A mounting frame and a clamping assembly are fixedly installed on the front of the auxiliary table. When in use, the side expansion plate can be rotated by the rotating shaft rod and movably connected to the buffer member to expand the loading and use area of the workbench. However, since assembly usually requires the assembly of multiple accessories, and the existing assembly is usually performed manually, it is difficult for manual assembly to completely and tightly assemble the various accessories to the pump body, resulting in a large amount of gaps after assembly, which makes the assembled centrifugal pump prone to air leakage.

[0004] To this end, we provide an assembly platform for centrifugal pump production to solve the above problems. Utility Model Content

[0005] The present application provides an assembly table for centrifugal pump production, which solves the problem that it is difficult to completely tighten the various accessories to the pump body during manual assembly, resulting in a large amount of gaps after assembly, making the assembled centrifugal pump prone to air leakage.

[0006] The present application provides an assembly platform for centrifugal pump production, comprising an assembly main platform and an assembly fixing mechanism, wherein the assembly fixing mechanism is provided above the assembly main platform;

[0007] The assembly and fixing mechanism comprises a rotating clamping assembly arranged on the top of the assembly main platform, and a pressing assembly is arranged above the rotating clamping assembly.

[0008] Preferably, the rotating clamping assembly includes a rotating connecting plate whose rotating shaft is connected to the top of the assembly main platform, and a rotating placement platform is provided on the top of the rotating connecting plate.

[0009] Preferably, a hydraulic clamping rod supporting the top plate is installed on the outer side of the rotating placement platform, and a clamping plate is fixedly connected to the outer side of the hydraulic clamping rod.

[0010] Preferably, a fixing pad is provided on the surface of the clamping plate, and the fixing pad is made of rubber.

[0011] Preferably, the pressing assembly includes a pressing platform welded to the rear end of the assembly main platform, a hydraulic drive pump is installed at the top of the pressing platform, a hydraulic telescopic rod is installed at the bottom end of the pressing platform, and a hydraulic top plate is provided at the bottom end of the hydraulic telescopic rod.

[0012] Preferably, a pressure sensor is installed on the inner side of the hydraulic top plate, and the pressure sensor is electrically connected to the hydraulic drive pump.

[0013] Preferably, an airtightness detection component is provided at the right end of the assembly main table, and the airtightness detection component includes a mounting table installed at the right end of the assembly main table, a compressed air pump is installed at the top of the mounting table, and the top pipeline of the compressed air pump is connected to a pneumatic joint.

[0014] It can be seen from the above technical scheme that the present application provides an assembly table for centrifugal pump production, which places the centrifugal pump seat on a rotating placement table. The rotation of the rotating placement table facilitates the change of the angle of the centrifugal pump seat, which facilitates the assembly of different positions of the centrifugal pump. At the same time, the centrifugal pump seat is clamped and fixed by controlling the contraction of the hydraulic clamping rod, thereby improving the stability of the centrifugal pump during assembly. Immediately after the pump disc, impeller and other components of the centrifugal pump are installed on the pump seat, the hydraulic drive pump is started to control the extension of the hydraulic telescopic rod, driving the hydraulic top plate to press the centrifugal pump. At the same time, the pressing force of the hydraulic telescopic rod is detected by the pressure sensor. After detecting that the pressure reaches a certain level, the hydraulic drive pump is controlled to stop operating to avoid damage to the centrifugal pump caused by excessive pressing force. Subsequently, the air pressure connector is connected to the assembled centrifugal pump, and the compressed air pump is started to pressurize and inflate the centrifugal pump, which is convenient for detecting the air tightness of the centrifugal pump. At the same time, the accessories of the centrifugal pump can be cleaned by the compressed air pump before assembly to ensure the assembly effect of the centrifugal pump.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. By setting up the assembly fixing mechanism, the centrifugal pump seat is placed on the rotating placement table. The rotation of the rotating placement table makes it easy to change the angle of the centrifugal pump seat, which is convenient for assembling the centrifugal pump in different positions. At the same time, by controlling the contraction of the hydraulic clamping rod, the centrifugal pump seat is clamped and fixed, thereby improving the stability of the centrifugal pump during assembly. Immediately after the pump disc and impeller of the centrifugal pump are installed on the pump seat, the hydraulic drive pump is started to control the hydraulic telescopic rod to extend, driving the hydraulic top plate to press the centrifugal pump, thereby improving the tightness of the centrifugal pump assembly. At the same time, the pressing force of the hydraulic telescopic rod is detected by the pressure sensor. After detecting that the pressure reaches a certain level, the hydraulic drive pump is controlled to stop operating to avoid damage to the centrifugal pump caused by excessive pressing force.

[0017] 2. Through the setting of the air tightness detection component, connect the air pressure joint to the assembled centrifugal pump, start the compressed air pump to pressurize the centrifugal pump, so as to facilitate the detection of the air tightness of the centrifugal pump. At the same time, the compressed air pump can be used to clean the accessories of the centrifugal pump before assembly to ensure the assembly effect of the centrifugal pump.

[0018] To sum up, this application fixes the centrifugal pump seat by setting up an assembly fixing mechanism, and then installs the required accessories into the pump seat. At the same time, the centrifugal pump is continuously pressed by a hydraulic telescopic rod to reduce the assembly gap between parts and improve the overall assembly effect.
