Liquid ring vacuum pump is suitable for brick and tile industry
Separate liquid ring vacuum pump is a new type of vacuum pump which combines the advantages of 2BV5 and 2SK. The pump has the characteristics of energy saving, high efficiency, reasonable structure, convenient maintenance, no oil, no leakage, high pumping speed with the same power and high vacuum.
The pump is widely used in explosion-proof, chemical industry, vacuum brick extruder, plastic pipe making, printing and dyeing, pharmaceutical, food, sugar making, building materials and other fields.
Compared with other types of mechanical vacuum pumps, liquid ring pumps have the following advantages:
The utility model has the advantages of simple structure, low manufacturing accuracy requirement, liquid ring vacuum pump and easy processing.
Compact structure, high pump speed, generally can be directly connected with the motor, brick factory vacuum pump, without deceleration device. Therefore, with a small structure size, we can get a large amount of exhaust gas and occupy a small area. Compressed gas is basically isothermal, that is, the temperature change of compressed gas is very small.
Because there is no metal friction surface in the pump chamber, there is no need to lubricate the pump, and the wear is very small. The function of vacuum pump is to extract gas molecules from the vacuum chamber, reduce the gas pressure in the vacuum chamber, and make it reach the required vacuum degree. Generally speaking, there is a large range from atmosphere to very high vacuum. So far, no vacuum system can cover this range. Therefore, different vacuum system configurations need to be selected in order to meet the requirements of process index, working efficiency and equipment working life of different products and different vacuum sections.
How to save energy for vacuum pumps used in brick and tile factories
Previous news and information introduced the types of vacuum pumps used in brick and tile factories and the main applications of vacuum extruders, but did not involve the energy consumption of vacuum extruders. Under the current conditions of a conservation-oriented society, how to save energy has become a very important task for every brick and tile enterprise, but also saved for brick and tile factories. Ben.
Because many brick and tile enterprises have long been extensive management, resulting in serious waste of energy. Extruders (including non-vacuum extruders and vacuum extruders) are the main equipment in brick and tile production line. They are very important for energy saving in brick and tile factories. However, improper configuration and use of extruders in many brick and tile factories cause considerable waste.
Because some brick mills have long adopted extensive management, in the past, vacuum extruders have been using high-power vacuum pumps, resulting in serious energy waste. Because of the poor sealing, the vacuum pump of 22KW is usually used in 450mm vacuum extruder, and the vacuum degree is often not up to the requirement. In recent years, some brick machine manufacturers have made some improvements on the sealing parts of the vacuum system, and the performance of the vacuum pump has been greatly improved. Now the mechanical vacuum pump of 5.5KW can fully meet the needs of 500 mm or even larger vacuum extruders, and can maintain a high vacuum for a long time.
By comparison, the power consumption has been reduced by four times, which is a positive achievement. However, this remarkable energy-saving measure has not been taken seriously by people. Many brick machine factories and even some brick machine factories that produce “energy-saving brick machines”, whether 450 or 400 vacuum extruders are usually equipped with 15 kW or even 22 kW vacuum pumps, invisibly increasing the power consumption of vacuum brick machines by nearly 3-4 times.
Unnecessary waste. In order to save energy for all vacuum extruders, 5.5 kW vacuum pump must be equipped for vacuum extruders under 600 type, so that the power consumption of vacuum system can reach a lower level. When installing, it should be noted that the corresponding air filter must be installed to avoid damaging the pump body when using MH-2 mechanical sliding valve oil-sealed vacuum pump. At the same time, the leakage and loss of sealing oil should be prevented during installation.
To sum up, energy saving has become an indispensable and important measure for every enterprise. Only the change of concept can completely change the fate of the enterprise. At the same time, the technological reform is also an indispensable step. Although there are many problems in energy saving of brick and tile enterprises at this stage, with the gradual progress of society, I believe that this is a difficult problem. The problem will be solved step by step.
