Liquid Ring Vacuum Pump in Special Ceramic Manufacturing Industry
Vacuum mud smelting is an important part of special ceramics. After vacuum treatment, the plasticity of the sludge is improved. After vacuum degassing, the sludge has a high density after extrusion, so the sintered product has a small deformation, high strength and good quality. The performance of liquid ring vacuum pump matched with vacuum mud refiner plays a key role in vacuum mud smelting.
Vacuum Pumps for Traditional Mud Refiners
According to market research, the traditional oil vacuum pumps such as slide valve pump, reciprocating pump and rotary vane pump are used in special ceramic factories. Taking slide valve pump as an example, due to the limitation of product design, there are the following shortcomings in the use process.
1. Poor environmental protection performance
As we all know, the sliding valve pump belongs to the oil-sealed rotary machinery vacuum pump, which needs vacuum oil to seal and lubricate, and consumes a lot of oil. Taking H-150 as an example, the oil injection volume needs 40-50L. After a certain period of service, oil leakage will inevitably occur due to the aging of the seal and the wear of the mechanical parts, which will cause oil stains on the production site. For example, the lubrication performance of vacuum oil is not good, and the mechanical friction between eccentric wheel and cylinder block will produce "oil burning" phenomenon when the sliding valve pump works, which is the diffuse oil fume on the work site and affects the health of workers.
2. Potential hazards of contaminated sludge
When the sliding valve pump shuts down, improper operation may cause vacuum oil to pour back into the mud refiner. The consequence is that the vacuum oil pollutes the mud, causing mud scrap and economic loss.
3. High maintenance costs
Sliding valve pump belongs to mechanical vacuum pump. There are friction parts inside, and there are many vulnerable parts. It needs oil and lubrication frequently, and the maintenance cost is high. Once the cylinder block is worn out, it is very difficult to repair it.
4. High cost of use
Vacuum oil taboos the entry of water, because water will emulsify vacuum oil and reduce the performance of oil products; because the sludge gas contains water, it is easy to contaminate the lubricating oil in the slide valve pump, so it must be added or replaced every day, and the use cost is high.
5. Poor efficiency in use
When the temperature is high in summer, the water is easy to gasify, which easily causes insufficient vacuum of oil ring vacuum pump. In order to solve these problems, some enterprises specially install air conditioning or exhaust fan for vacuum pump, which wastes energy greatly and increases the expenditure of enterprises.
Reciprocating vacuum pumps, like sliding valve pumps, also have some shortcomings in use, such as poor environmental protection, high maintenance cost and high noise.
Liquid Ring Vacuum Pump for mud refiner
In view of the shortcomings of the above oil-type vacuum pump, the water ring vacuum pump produced by our company has the characteristics of simple structure, reliable operation, energy saving, high efficiency and oil-free. It has been innovatively applied in the ceramic and electric ceramic industries, and has been recognized by more and more users.
1. Simple structure and long life
Liquid Ring Vacuum Pump is sealed by water and centrifugal force is produced by the rotation of impeller. Gas is compressed by the volume periodic change of the cavity between impeller and pump body, and exhaust is carried out. There is no contact between impeller and pump body, no mechanical friction and long service life.
2. No refueling and environmental protection
The liquid ring vacuum pump uses water as working fluid, without friction parts inside, without lubricating oil and vacuum oil, thus eliminating oil and gas pollution to the work site and mud, and reducing the workload of operators and labor intensity.
3. Liquid Ring Vacuum Pump is easy to use, stable in operation and small in maintenance, so that operators can use it easily and conveniently.
