Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal pumps, in particular to a centrifugal pump protection device. Background Art

[0002] A centrifugal pump works by using the rotation of the impeller to cause water to move centrifugally. Before starting the pump, the pump casing and the suction pipe must be filled with water, and then the motor is started so that the pump shaft drives the impeller and water to rotate at high speed. The water moves centrifugally and is thrown to the outer edge of the impeller and flows into the water pressure pipeline of the pump through the flow channel of the volute pump casing.

[0003] According to Chinese patent CN212202585U, a vertical centrifugal pump protective device is provided. When the centrifugal pump is installed, the rubber sleeves of the delivery pipes on both sides of the pump housing are taken out. After the centrifugal pump is installed, the power switch of the drive motor is turned on, and the centrifugal pump starts to work. The threaded rod welded on the base is sleeved with a shock-absorbing spring and a gasket that are slidably connected to the second fixed plate at the bottom of the pump housing, which can play a shock-absorbing role when the drive motor is working. The dust cover welded on the top of the drive motor can prevent dust from adhering to the surface of the drive motor during long-term use. After the centrifugal pump is used, the power switch of the drive motor is turned off.

[0004] The above-mentioned device is not effective in protecting the centrifugal pump body. Although only a dust cover is set on the top to achieve dust prevention, there is no protective component around the pump body, resulting in the dust prevention effect not achieving the expected effect. The pump body adopts a design of two shock-absorbing springs and threaded columns, which makes the fixing plate fluctuate up and down during shock absorption. Long-term vibration will also cause the nut to loosen, further reducing the safety of the device protection. Therefore, a centrifugal pump protection device is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a centrifugal pump protection device, which has the advantages of preventing dust from entering the surface of the pump body as much as possible when the centrifugal pump is protected, and the reliability of the pump body itself after installation is not affected. It solves the problem that when protecting the existing centrifugal pump, only a dust cover is set on the top to achieve the dust-proof effect, but no protection components are set around the pump body, resulting in the dust-proof effect not achieving the expected effect.

[0006] To achieve the above object, the utility model provides the following technical solutions: a centrifugal pump protection device, comprising a base, the top of the base is fixedly connected with a protection bottom shell, and the outer surface of the protection bottom shell is provided with a protection component;

[0007] The protective assembly includes a protective shell, which is movably connected to the outer surface of the protective bottom shell, two sleeves are fixedly connected to the top of the base, spring shock absorber bodies are fixedly connected to the interior of the two sleeves, movable plates are movably connected to the tops of the two spring shock absorber bodies, mounting plates are fixedly connected to the tops of the two movable plates, a protective top cover is fixedly connected to the top of the protective shell, a connecting plate is fixedly connected to the bottom of the protective top cover, and fixed plates are fixedly connected to the left and right sides of the protective shell; a pump housing is fixedly connected to the top of the mounting plate, and a motor is fixedly connected to the top of the pump housing.

[0008] Furthermore, a protective opening is provided on the front side of the protective bottom shell, and a cover plate is hinged on the front side of the protective bottom shell.

[0009] Furthermore, hydraulic rods are fixedly connected to the left and right sides of the protective bottom shell, and the protective outer shell is movably connected to the outer surface of the protective bottom shell through the two hydraulic rods.

[0010] Furthermore, two limiting grooves are provided inside the protective bottom shell, and the movable plate is slidably connected to the protective bottom shell via the two limiting grooves.

[0011] Furthermore, a delivery pipe is fixedly connected to the front of the pump housing, U-shaped grooves are provided on the front and back of the protective shell, and sealing rubber pads are fixedly connected to the front and back of the protective shell via the U-shaped grooves.

[0012] Furthermore, a cavity is provided inside the two fixing plates, and the two connecting plates are located inside the two fixing plates through the cavity. The two fixing plates are movably connected inside with a clamping column, and the two connecting plates are clamped with the two fixing plates through the clamping column.

[0013] Furthermore, two heat dissipation mesh holes are provided inside the protective shell, and a heat dissipation fan body is fixedly connected to the inner wall of the protective shell.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial effects: the centrifugal pump protection device, when the motor on the top of the pump casing is fixed to the top of the movable plate via the mounting plate, can play the role of a hydraulic rod to drive the protective outer shell to move downward, thereby forming a protective outer shell and a protective bottom shell combined together, and the movable plate and the mounting plate can be prevented from loosening as much as possible during the shock absorption process, thereby achieving the effect of protecting the centrifugal pump; when the centrifugal pump body is working, the cooperation between the protective top cover and the protective outer shell can play a more comprehensive dustproof effect, thereby achieving a better dustproof effect for the centrifugal pump body, and since a cooling fan body is provided inside the protective shell, the heat generated by the centrifugal pump body when it is working can be sucked out through the cooling fan body to ensure that the internal ambient temperature is at a constant temperature, thereby achieving the effect of multi-directional protection of the centrifugal pump body.
