AI Technical Summary

Technical Problem

When existing horizontal centrifugal pumps deal with fluids containing larger particulate matter, it is difficult to effectively filter particulate matter, resulting in wear and damage to internal parts.

Method used

A horizontal centrifugal pump including a filter device, a lubrication device and a cooling device is designed. The filtering device uses the design of bevel blocks and slide rods to ensure that the water inlet is not blocked and filters larger particles. The lubricating device automatically replenishes and recovers lubricating oil to reduce friction through the fitting of the push rod and sliding door. The cooling device uses the water flow to reduce the temperature of the lubricant oil through the water suction pump and the water pipe.

Benefits of technology

It effectively prevents particulate matter accumulation and wear, extends the service life of pump parts, reduces maintenance costs and environmental pollution risks, and improves the operational efficiency of the pump and the heat dissipation efficiency of the lubrication system.

Abstract

The invention discloses a horizontal centrifugal pump capable of preventing accumulation and abrasion of medium particles, and relates to the technical field of horizontal centrifugal pumps, the horizontal centrifugal pump comprises a base, a motor is fixedly mounted at the top of the base, a rotating shaft is fixedly mounted at the output end of the motor, and a rotating disc is fixedly mounted at the end, away from the output end of the motor, of the rotating shaft; a water suction box is fixedly mounted at the top of the base, a connecting ring is fixedly mounted on the right side of the water suction box, a filtering device is arranged in the water suction box, a lubricating device is arranged at the top of the connecting ring, and a cooling device is arranged in the connecting ring. The filtering device comprises a water inlet, a water outlet, a filtering disc, a sliding rod, a first inclined block, a second inclined block, an L-shaped rod and a sealing ring, large particles are filtered through the filtering disc and prevented from entering the pump, the service life of a rotating disc and other parts is prolonged, the frequency of equipment maintenance and part replacement is reduced, and therefore the maintenance cost is reduced.
