How to find the causes and repair water chiller

In the process of operation and use of air conditioners in general and chillers in particular, there are many incidents that make users face with many difficulties. In this article we provide readers with the most basic knowledge to determine the causes, phenomena and remedies when air conditioning (chiller) is in trouble.To help you deal with problems during the machine operation and use, we would like to introduce some of the following common problems:

Operation control of GRH3 air compressor

Some attentions of desicant air dryer (heatless type) maintenence

Compressed air system in factory plays an important role. In order to ensure the stable operation during the manufacturing process, the regulary maintenance is nescessary . However, in fact there are many different problems  such as: Air compressors, dusty air dryers, high engine room temperatures, unsecured wind convection ... lead to reduce using  time of compressor accessories (air filter, oil filter, oil separator ...). On the other hand, the recommended  maintenance   in some factories is not seriously followed and there are deviations. To extend the life of the machine as well as compressor components and ensure operate safely Air compressors are very important to maintain regularly and technically correct.Air compressors, dusty air dryers, high engine room temperatures, unsecured wind convection ... lead to reduced use time of compressor accessories (air filter, loc oil, oil separator ...). On the other hand, the maintenance (maintenance) recommended by the manufacturer in some factories is not guaranteed and there are deviated. To lengthen  longevity  of mạchine as well as compress

Classification, working priciple and application of vacuum pump

Monday - 19/08/2019 09:35

Vacuum pump is a equipment which is specialized device to remove gas, liquid, steam from the limited and closed space to create a vacuum environment or almost near vacuum. 

1. Vacuum pump classification

Classification, working priciple and application of vacuum pump

  - Classification by vacuum pressure.

  • Super high pressure vacuum pump.(p <10−5Pa),
  • High pressure vacuum pump (0.1Pa>p>10−5Pa)
  • Medium pressure vacuum pump  (100Pa>p>0.1Pa),
  • Low pressure vacuum pump (p>100Pa).

  - Classification by structure:

  • Piston vacunm pump ;

  • Rotary vane pump;

  • Double stage rotor vane vacuum suction pump ;

  - Clssification by working fluids:

  • Oil-free vacuum pump;
  • Water-free vacuum pump;
  • Dry vacuum pump.

2. The working principle of vacuum pump.

In vacuum pumps, there are chambers that are usually in between pistons or vanes (depending on the type of vacuum pump). The vacuum environment is created by drawing air, vapor, and liquid in space through the operation of the working chambers in the pump. The volume of the working chambers of the pump changes periodically. During the working process, when the volume of the working chambers increases, the pump will perform the suction of the working fluid (water or oil), air and steam. This mixture will gradually be compressed and removed from the pump's door. Once removed from the pump, the liquid and air are separated again. The liquid will follow the condenser and become the fuel supplied to the pump, forming a closed circle. For non-liquid pumps, the working chambers are designed closely.

3. Wide application of vacuum pump in industry.

 Vacuum pumps have needed by manufacturer since they was newborn because of their excellent usage. Today, vacuum pumps are more and more widely used  playing a particularly important role in production lines and industrial plants.
– Application in Medical Industry:  The diagnosis and treatment process will be more safe and accurate, higher efficiency. More than 3,000 hospitals and health centers around the world trust and use vacuum pump systems into their workflows.

–Application of vacuum pump in printing:

Vacuum pump plays an vitual role in cteating perfectly printing products. Vacuum pump is prepaired before printing to squeeze into the print batch and remove the dust in the paper's surface before spraying ink.

– Application of vacuum pump in wood processing technology: 

Helping the coating process of wood surface is quickier, avoiding the mixed impurities to make the surface more smooth.

Application of vacuum pump in the process of manufacturing plastic pipes: 

Play a decisive role in shaping product size and shape.

Application of vacuum pump in food preservation:  

Food preservation process is longer, avoid oxidation occurs, and  keep fresh taste.

Application of vacuum pump in paper production technology:

Minimize the foaming process of the powder line, thereby preventing the precipitation process, creating smooth and quality paper products.
