Matters needing attention in maintenance process of slurry pump

When the slurry pump is in use, many manufacturers choose to send to professional maintenance department to repair. Some people choose to repair themselves, but because they are not professional maintenance personnel, they often can not grasp the details that need to be paid attention to in the process of maintenance, even do not know. Many people will ask, "what should we pay attention to in the maintenance?", let's let's let's tell you the following.

Many times people think that there is no need for overhaul and overhaul for a small fault. For example, when the pump leaks, many people fill in some dry soil at the inlet pipe mouth before starting each time in order to save trouble. Then, water the soil to the bottom valve so that the bottom valve can not leak. This method seems easy to use, but it is not actually desirable. Because when the pump starts to work, the sand in the bottom valve will enter the pump with water, which will wear the impeller, pump shell and shaft, which will seriously affect the service life of the pump.

The correct maintenance method of slurry pump should be to repair the bottom valve. If there is no way to repair it, it is necessary to replace the bottom valve in time, but it can not be left to the hand; if there are other faults, it is also necessary to timely eliminate it, and the unit must not be allowed to work with disease. For example, if it is found that the packing of the pump shaft is seriously worn, the packing should be added in time, otherwise the air leakage will be caused to the pump shaft packing, and the cavitation phenomenon will occur in serious cases, which will accelerate the damage of the impeller, which directly affects the service life of the pump; if the pump vibrates violently, it is necessary to stop the pump immediately for inspection, otherwise, the bending deformation of the pump may cause safety accidents and so on.

The wide development use of slurry pump

Slurry pump is mechanical device. Mainly applicable to: mining, power plant, dredging, metallurgy, chemical industry, building materials and petroleum and other industries. The name of slurry pump is a kind of centrifugal pump from the point of view of conveying medium. In addition, slurry pump can be divided into different types from different angles. In addition to pumping water, the pump can also pump gas, solid, solid-liquid mixture - mineral slurry! Water pump electricity accounts for a large proportion of the total national electricity. The energy saving situation of water pump has an important impact on the national economy. Water pump not only plays a positive role in energy saving, but also plays an important role in the process of thermal power emission reduction. Slurry pump not only saves 4% - 8% energy compared with similar products, but also contributes to getting rid of haze.
