The following safety information related to pump operation and maintenance should be carefully followed and proper procedures followed to avoid personal injury and equipment damage. All statutory requirements related to this equipment must be complied with at all times.
Do not apply heat to the impeller hub or air intake to aid in impeller removal. Heating may cause impeller crushing, injury or equipment damage.
Do not run the pump at zero or very low flow for extended periods of time. Failure to follow this warning may result in overheating of the pump and evaporation of the pumped fluid, creating very high pressures. Such actions could result in serious personal injury or equipment damage.
Check drive motor rotation before installing drive belts or couplings. Incorrect motor rotation may result in personal injury or equipment damage.
Do not put very hot or very cold fluid into the pump at ambient temperature. Thermal shock can cause the wet end parts of the pump to break. Pumps must be considered rotating machinery and pressure vessels. All relevant safety precautions and procedures for this type of equipment should be followed during installation, operation and maintenance of the pump.
In the case of auxiliary equipment associated with the pump (e.g. motors, belts, drive couplings, reducers, variable speed drives, etc.) during installation, operation and maintenance, all relevant operating instructions should be consulted and recommended procedures should be followed.

Today we will understand the precautions of forth pump operation. CNSEM ®  will give you a brief introduction. Let's have a look together.

When the forh pump is running, it is necessary to check the operation of the bearing assembly regularly. If the bearing is heated during open operation, it is necessary to stop the pump and wait for the pump shaft to cool down before running again. If the temperature of the bearing is still too high, and the temperature continues to rise, it is necessary to disassemble the bearing assembly of the pump shaft to check what the reason is.

General bearing heating is mostly caused by too much grease, or by magazines in grease. The amount of bearing grease should be appropriate, but also need to ensure cleanliness, and grease should be added regularly.

The performance of the forth pump deteriorates with the increase of the wear interval of the impeller and the protection plate, and the efficiency decreases. Therefore, the impeller should be adjusted upward in time, so as to maintain a certain interval so that the forth pump can maintain high efficiency operation.

When the forth pump wear cannot meet the needs of the system, it should be replaced in time.

A slurry pump is a mechanical device used to transport liquids containing solid particles. It is widely used in mining, metallurgy, coal, electric power, chemical industry and other industries. The main function of a slurry pump is to transport slurry from one place to another. It is capable of transporting liquids containing high concentrations of solid particles, such as slag, coal cinder, ash, etc. The main components of the slurry pump include pump body, impeller, bearing, sealing device and so on.
With the continuous advancement of the industrialization process, the demand for slurry pumps continues to increase. Especially in mining, metallurgy and other industries, the demand for slurry pumps is increasing day by day. Therefore, the market prospect of the slurry pump industry is very broad.
With the continuous advancement of science and technology, the technology of slurry pumps is also developing. At present, the technology of slurry pump has become more and more mature, and its performance has been continuously improved. For example, some new slurry pumps adopt a high-efficiency and energy-saving design, which makes the pump more efficient and consumes less energy. At the same time, the application of some new materials also makes the service life of the slurry pump longer.
In general, the development prospect of the slurry pump industry is very broad. In the future, with the continuous development of science and technology, the technology of slurry pump will be more mature and its performance will be more superior. At the same time, with the continuous improvement of environmental protection awareness, the green environmental protection performance of slurry pumps will also receive more attention. Therefore, the slurry pump industry will usher in a broader development prospect.
A slurry pump is a pump used to transport high-concentration mixtures containing solid particles. According to different usage scenarios and needs, slurry pumps can be divided into many different classifications or types.
1. Horizontal centrifugal slurry pump: This is the most common type of slurry pump, mainly used to transport high-concentration slurry. The pump has a compact structure, smooth operation, and can withstand high pressure and large flow.


2. Vertical submerged slurry pump: This type of pump is usually installed in deep wells to pump groundwater and transport slurry. It has a smaller footprint and higher operating efficiency.



3. Heavy-duty slurry pump: This type of pump has a stronger structure and is suitable for transporting denser slurry, such as coal gangue and sludge.



4. Slurry pump: Similar to the slurry pump, the slurry pump is also a pump used to transport high-concentration mixtures containing solid particles. The difference is that mud pumps are usually used in drilling, prospecting and other processes in oil and gas industries.
In short, the slurry pump has a wide range of application fields and a variety of product categories, which can meet the needs of different users.

Vertical Slurry Pump Model: SV/300T with Direct Discharge
Q: 1200m3/h, H: 15m, Speed: 600rpm
Flange: DN300, PN10

When the rolling bearing is working, the inner seat ring is matched with the journal, and the outer seat is matched with the bearing seat, and the inner seat can be rotated during the work, but the rotation of the outer seat ring has a more serious impact on the bearing life, so the inner seat ring should be rotated as much as possible during the design.
In the rolling bearing with the inner seat rotating, the inner seat and the journal, the outer seat and the bearing seat must be over-matched, but the inner seat should be tighter than the outer seat, so that when the shaft is stretched due to the temperature increase in the work, it can have an adjustment effect. The bearing seat has enough steel to prevent the working life of the bearing from being affected by the deformation of the support.
When there are rolling bearings at both ends of the shaft, one end of the bearing can be fixed on the bearing seat, and the other end must have an axial clearance, which can produce axial movement in order to eliminate the influence of the change in the length of the shaft on the bearing.
After the desulfurization pump bearing seat ring is matched, the bearing cover is added outside, and the embedded flange is just against the bearing outer seat ring, and then the bearing cover is fixed on the bearing seat with screws. If the bearing is required to have the possibility of axial movement, there can be a gap between the bearing outer seat ring and the bearing cover, or a soft gasket can be added between the bearing cover and the bearing seat to adjust.
