One side of the rubber pad 35 extends to the outside of the pump body 1. While the noise reduction mounting mechanism 3 cooperates to assist in the installation of the sound insulation side panel 31, the rubber pad 35 is in direct contact with the pump body 1 to reduce the overall vibration of the pump body 1, which plays a role in primary noise reduction. By arranging the sound insulation side panel 31, the sound-absorbing bottom panel 32, the foam plastic top panel 33, and the silencer cotton 34, the reflected noise is reduced, and the noise is effectively absorbed at the construction site, which plays a role in secondary noise reduction and improves the noise reduction effect at the work site. The cooling fan 22 and the heat dissipation fins 25 cooperate to perform multi-stage heat dissipation treatment, which extends the service life of the equipment and meets the requirements of normal use.

[0030] A step further, such as Figure 1-Figure 4As shown: reinforcement blocks 38 are installed on all four sides of the sound insulation side panel 31, and a fourth positioning bolt 39 extending to the inside of the mounting seat 30 is installed on the outer side of one of the reinforcement blocks 38, and a fourth positioning bolt 39 extending to the inside of the foam plastic top plate 33 is installed on the outer side of the other reinforcement block 38.

The reinforcement block 38 and the mounting seat 30 are reinforced and installed twice by the fourth positioning bolt 39, thereby improving the stability of the equipment during installation.

[0031] The above solutions still have the problem of poor daily protection effect, such as Figure 1-Figure 4 As shown: In this solution, a mounting cover 21 is installed on the side of the casing 2 away from the pump body 1, and a cooling fan 22 is installed inside the mounting cover 21.

The mounting flange 11 is used to assist in connecting the sealing disk 12 and the pump body 1 during installation, and the installation of the mounting flange 11 serves to reinforce the sealing. A fixing plate 13 is installed on the top of the mounting flange 11 and the sealing disk 12, and a first positioning bolt 14 extending to the inside of the mounting flange 11 and the sealing disk 12 is installed inside the fixing plate 13. A second positioning bolt 15 extending to the inside of the pump body 1 is installed on the outside of the sealing disk 12. The mounting flange 11 and the sealing disk 12 are reinforced once by the fixing plate 13 and the first positioning bolt 14, and the sealing disk 12, the mounting flange 11 and the pump body 1 are reinforced twice by the second positioning bolt 15, so as to facilitate quick disassembly and assembly during use.

[0033] The above solutions also have the problem of poor stability when the equipment is used, such as Figure 1-Figure 3As shown, in this solution, a junction box 16 is installed on the top of the pump body 1, a support plate 17 is installed on one side of the junction box 16, and equidistantly distributed reinforcement plates 18 are installed inside the support plate 17. One side of the reinforcement plate 18 is connected to the pump body 1, and one of the reinforcement plates 18 is connected to the sliding mounting plate 36. A rotor is installed inside the pump body 1, and a stator is installed on one side of the rotor. The output end of the rotor is connected to a connecting shaft that passes through the sealing disk 12. The entire equipment is supported by the support plate 17, and the reinforcement plate 18 is used to cooperate with the pump body 1 and the support plate 17 for reinforcement installation, thereby improving the stability of the equipment during use.

[0034] Working principle:

[0035] like Figure 1-4 As shown:

[0036] By arranging the pump body 1, the casing 2, the noise reduction mounting mechanism 3 and the cooling water pipe mounting protective cover 4, a permanent magnet ring is installed at the mounting position of the pump body 1 and the casing 2. When in use, the sliding mounting plate 36 after adjustment is limited by the third positioning bolt 37, the foam plastic top plate 33 and the sliding mounting plate 36 are reinforced and installed once by the fourth positioning bolt 39, and the reinforcement block 38 and the mounting seat 30 are reinforced and installed twice by the fourth positioning bolt 39, thereby improving the stability of the equipment during installation;

[0037] The cooling fan 22 is used to dissipate heat from the pump body 1 and the internal equipment of the casing 2, and the mounting cover 21 is used to prevent dust from entering the cooling fan 22.

[0038] The heat dissipation fins 25 conduct the entire temperature of the housing 2 to achieve heat dissipation effect;

[0039] Install protective covers 4 on the cooling water pipes to protect them from dust on a daily basis;

[0040] The sealing disc 12 and the pump body 1 are auxiliary connected by the mounting flange 11 during installation. The mounting flange 11 is installed to strengthen the sealing process. The mounting flange 11 and the sealing disc 12 are reinforced once by the fixing plate 13 and the first positioning bolt 14.

[0041] The sealing disc 12, the mounting flange 11 and the pump body 1 are reinforced for a second time by the second positioning bolt 15, which facilitates quick disassembly and assembly during use. The entire device is supported once by the support plate 17, and the reinforcement plate 18 is used to reinforce the pump body 1 and the support plate 17, thereby improving the stability of the device during use.

[0042] While assisting in the installation of the sound insulation side panels 31 through the cooperation of the noise reduction installation mechanism 3, the rubber pads 35 are in direct contact with the pump body 1 to reduce the overall vibration of the pump body 1, thereby achieving a primary noise reduction treatment. By arranging the sound insulation side panels 31, the sound-absorbing bottom plate 32, the foam plastic top plate 33, and the sound-absorbing cotton 34, the reflected noise is reduced, and the noise is effectively absorbed at the construction site, achieving a secondary noise reduction treatment, thereby improving the noise reduction treatment effect at the work site. The multi-stage heat dissipation treatment is carried out by cooperating with the cooling fan 22 and the heat dissipation fins 25, thereby extending the service life of the equipment and meeting the requirements of normal use.
