Claw pump application - in the insulating brick industry

claw pump in the application of the autoclaved aerated insulation block industry

1. The autoclaved aerated insulation block the development of the industry prospects

cause of land pollution, and affects normal ChouShui pit agricultural production;

caused by environmental pollution, Combustion produces a large amount of dust and harmful gases) Environmental protection.

will produce waste utilization of coal ash, weight ease has markedly improved for heat preservation and sound insulation.

countries for refractory assess, sound insulation performance, heat insulation heat storage performance, and the requirement of increasing the thermal resistance, promoted the autoclaved aerated insulation brick product demand rising.

2。 Autoclaved aerated since the current vacuum insulation block industry application solutions and troubling

customer now is to finalize the design of a after a heating hot steam at 100 ℃ of brick brick mabr extraction from 1000 to 400 mbar;

the original configuration is a 18. 5 kw water ring pump, but due to a high temperature water ring pump suction speed slower and slower requires 1 hour of time. Seriously affected the work efficiency.

water ring pump cavitation is more serious, at the same time, the seals will be because the reason such as the high temperature can't normal use;

customer done before using hot steam gas purging an hour, caused by the waste steam is relatively serious, the cost of investment is relatively large.

3。 Vacuum package before and after installation and debugging problems

customer now is to finalize the design of a after a heating hot steam at 100 ℃ of brick brick mabr extraction from 1000 to 400 mbar;

the original configuration is a 18. 5 kw water ring pump, but due to a high temperature water ring pump suction speed slower and slower requires 1 hour of time. Seriously affected the work efficiency.

water ring pump cavitation is more serious, at the same time, the seals will be because the reason such as the high temperature can't normal use;

customer done before using hot steam gas purging an hour, caused by the waste steam is relatively serious, the cost of investment is relatively large.

4。 Atlas can give the autoclaved aerated insulation block industry design

pre condensing type selection design

system including: straight cooling condenser, cold water tower, cold water tower evaporation ventilation; Straight cold condenser, cooling tower and vacuum water pump installed on the existing space, ventilation cooling tower fan installed on the outer wall, the induced air channel;

the cooling tower is designed according to the maximum heat load limit circulation flow: 35 t/h

cooling energy dissipation capacity, Including evaporation ventilation, cold water cycle) :

5。 Atlas can bring the autoclaved aerated insulation block industry value

energy consumption

old installed power: 18. 5 kw

new installed power: 18. 3 kw

the old processing cycles: 1 hour

new processing cycle: 26 minutes

the overall energy efficiency: 2. 33 times

conclusion: new type selection are conducted according to the limit of maximum load, the actual energy efficiency will be greater than 2. 33 times

the disadvantage of water ring water pump

simple structure and manufacture accuracy is not high;

the efficiency is low, general at around 30%;

vacuum degree is low, not only because this is limited by the structure of the, more important is restricted by working liquid saturation vapour pressure;

in the process of using impeller cavitation happens, reduce the service life of the equipment, increase the maintenance cost;

need to form a complete set of cooling water at the same time, a complete set of unit power is larger at the same time, increased the operation cost.

the advantages of vacuum pump dry claw

machining precision is high, the stainless steel rotor, corrosion resistance, pump cavity wall coating, applicable to a variety of demanding applications.

high efficiency, high vacuum degree, can improve the production efficiency, increase revenue;

fast removable, easy to maintenance, can reduce the maintenance cost;

the air-filled, save water, can reduce the cost;

the whole equipment power is low, can variable-frequency operation, energy saving effect is remarkable.

As we have known for quite some time, the success of JT in the future will depend greatly on our ability to strike a balance between valuable human insight and interaction with technology.
