Technical Field

[0001] The invention relates to the technical field of horizontal centrifugal pumps, and in particular to a horizontal centrifugal pump capable of preventing medium particles from accumulating and abrading. Background Art

[0002] Horizontal centrifugal pumps that prevent medium particle accumulation and wear are usually designed to handle fluids containing particulate matter. This type of pump uses special design, particle filtering, optimized impeller shape, increased pump cavity clearance, etc. to reduce the accumulation of particles inside the pump, thereby effectively reducing wear and extending the service life of the pump.

[0003] The patent with the patent announcement number CN205895624U involves the technical field of horizontal centrifugal pumps. The patent consists of a base, a pump body, an impeller, stainless steel fixed impeller screws, a mechanical seal, a screw plug, a stainless steel cover plate, a one-piece pump cover, a steering sign, a motor, a special maintenance track, a motor lower cover plate, and a movable wheel. The use of stainless steel inlays and motor lower flanges improves the overall aesthetics of the centrifugal pump. The one-piece pump cover is directly connected to the lower bearing end cover of the motor, which improves the assembly efficiency, increases the height, and also increases the temperature resistance. The motor shaft directly leads to the pump cover to improve the concentricity and increase the stability of the motor. The structure of the horizontal centrifugal pump is more simplified and reasonable, and the installation and processing are convenient, with fewer processes, which greatly improves the work efficiency and economic benefits.

[0004] In the above patent, the aesthetics of the whole centrifugal pump is improved by using stainless steel inlay and motor lower flange. The one-piece pump cover is directly connected to the motor lower bearing end cover, which improves the assembly efficiency, increases the height, and also increases the temperature resistance. The motor shaft directly leads to the pump cover to improve the concentricity and increase the stability of the motor. However, it is difficult to filter and block some larger particles in the water during operation, which easily causes the particles to directly enter the centrifugal pump and damage the internal parts.

[0007] According to the above technical solution, the surfaces of inclined block 1 and inclined block 2 that are close to each other are set as inclined surfaces, and spring 1 is set between the slide rod and the filter plate. The inclined surface is set to ensure that inclined block 2 can smoothly push inclined block 1 when rotating, and spring 1 is set to ensure that the slide rod can achieve autonomous reset.

[0008] According to the above technical scheme, the lubrication device includes a push rod 1, a fixed block, an elastic telescopic rod, an oil tank and a sliding door.

[0016] The present invention provides a horizontal centrifugal pump that prevents medium particles from accumulating and wearing. It has the following beneficial effects: (1) In the present invention, the movement of the push rod inclined block drives the sliding rod to start moving. The sliding rod moves and extends to ensure that the water inlet is not blocked, so that the centrifugal pump can normally suck in liquid, and prevents the water inlet from being blocked, resulting in unstable water flow entering the pump body and causing wear and damage to the components. Larger particles are filtered through the filter disc to prevent these particles from entering the pump, thereby extending the service life of the turntable and other components, reducing the frequency of equipment maintenance and component replacement, and thus reducing maintenance costs. The movement of the L-shaped rod drives the sealing ring to start moving, and the sealing ring moves to seal the connection between the connector and the water inlet, which can effectively prevent liquid from leaking from the connection between the water inlet and the connector, ensuring that the liquid is confined to the flow channel inside the pump body, preventing the liquid from flowing out.

[0017] (2) The invention opens the oil outlet of the oil tank by moving the sliding door. After the oil outlet of the oil tank is opened, the lubricating oil flows out through the oil outlet and contacts the rotating shaft and the output end of the motor, which greatly reduces the friction force, reduces the wear of the components, and enables smoother operation, thereby extending the service life of key components such as bearings and pump shafts, and preventing excessive wear of the connection caused by a large friction coefficient during high-speed rotation. The lubricating oil that falls from the rotating shaft to the bottom of the inner wall of the connecting ring is sucked out by the suction pump and re-enters the oil tank for recycling. The recycling of lubricating oil can reduce the processing cost of lubricating oil. By recycling and reusing lubricating oil, the discharge of waste lubricating oil can be reduced, thereby reducing the risk of environmental pollution. Impurities are removed by filtering so that the lubricating oil can continue to play an effective lubricating role, thereby extending the service life of the lubricating oil, reducing the frequency of lubricating oil replacement, and reducing operating costs. The scraper rod moves to scrape off the impurities filtered from the lubricating oil on the filter plate, so that these accumulated impurities can be removed in time, so that the filter holes of the filter plate remain unobstructed, ensuring that the lubricating oil can be filtered and returned to the lubrication system in time.

[0018] (3) The invention, through the operation of the water suction pump, causes water to flow inside the water pipe so that the outer wall of the water pipe contacts the lubricating oil. The continuous flow of water can effectively reduce the temperature of the lubricating oil and keep it within a suitable operating temperature range, thereby preventing the lubricating oil from deteriorating or losing its lubricating properties due to excessive temperature. The movement of the moving rod drives the push plate to start moving. The movement of the push plate stirs the lubricating oil so that the lubricating oil at different positions can fully contact the water-cooled heat dissipation surface, making heat transfer more efficient, thereby improving the heat dissipation efficiency of the entire lubricating oil cooling system.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Larger particles are filtered through the filter disc 8 to prevent these particles from entering the pump, thereby extending the service life of the turntable 4 and other components, reducing the frequency of equipment maintenance and replacement of components, and thus reducing maintenance costs.

[0023] The side of the inclined block 10 and the inclined block 2 11 that is close to each other is set as an inclined plane, and a spring 1 is set between the slide rod 9 and the filter plate 8. The inclined plane is set to ensure that the inclined block 2 11 can smoothly push the inclined block 10 when rotating, and the spring 1 is set to ensure that the slide rod 9 can achieve self-reset.

[0024] When this embodiment is working: first check the working state of the motor 2 to ensure that there will be no problems when the machine is working, then connect the water inlet 6 and the water outlet 7 respectively, and start the motor 2 after confirming that the connection is completed, so that the motor 2 drives the shaft 3 to start rotating, and the rotation of the shaft 3 drives the turntable 4 to start rotating.

After the oil outlet of the oil tank 144 is opened, the lubricating oil flows out through the oil outlet and contacts with the rotating shaft 3 and the output end of the motor 2, which greatly reduces the friction force, reduces the wear of the components, enables smoother operation, prolongs the service life of key components such as bearings and pump shafts, and prevents excessive wear of the connection caused by a large friction coefficient during high-speed rotation.

The scraper rod 1410 is fixedly installed at the bottom of the push rod 141, and the filter plate 1411 is fixedly installed at the bottom of the inner wall of the connecting ring 51.

After the oil outlet of the oil tank 144 is opened, the lubricating oil flows out through the oil outlet and contacts with the rotating shaft 3 and the output end of the motor 2, which greatly reduces the friction force, reduces the wear of the components, enables smoother operation, extends the service life of key components such as bearings and pump shafts, and prevents excessive wear of the connection caused by the large friction coefficient during high-speed rotation; when the sliding door 145 moves, the long rod 149 is driven to start moving, and the long rod 149 moves to push the switch button 148 to move at the control end of the oil suction pump 146, so that the switch button 148 starts the oil suction pump 146 to start working, and the oil suction pump 146 will fall from the rotating shaft 3 to the inner wall of the connecting ring 51 when it is working.

By filtering, the impurities are removed so that the lubricating oil can continue to play an effective lubricating role, thereby extending the service life of the lubricating oil, reducing the frequency of lubricating oil replacement, and reducing operating costs. When the scraper rod 1410 moves to scrape off the impurities in the filtered lubricating oil on the filter plate 1411, these accumulated impurities can be removed in time, so that the filter holes of the filter plate 1411 remain unobstructed, ensuring that the lubricating oil can be filtered in time and returned to the lubrication system.

[0034] When the slide bar 9 moves, the push block 153 is driven to move. The push block 153 moves and pushes the switch button 2 154 to move at the control end of the water suction pump 151, so that the switch button 2 154 starts the water suction pump 151 to start working.
