Circulating Water Cooling Device For Vacuum Unit

The water ring vacuum unit is mainly operated by roots pump and is made of water ring pump in series. The water ring pump selected by the water ring vacuum unit is more advantageous than other vacuum pumps, because it not only overcomes the limitation of pressure difference when a single water ring pump is used, but also keeps the low pumping rate under certain pressure, and at the same time, it also retains the advantages of rapid operation of the roots pump and relatively large pumping rate.

It can be used to extract a large amount of condensable steam, especially when the mechanical vacuum pump of gas-ballast oil seal is not capable of removing condensable steam, or the solvent used can deteriorate the pump oil and thus affect the performance, or the vacuum system does not allow oil pollution is more obvious. If equipped with explosion-proof motor and electrical appliances, and comply with the corresponding safety rules, it can also remove flammable and explosive gas.

Therefore, the water ring pump unit can be widely used in the chemical industry vacuum distillation, vacuum evaporation, dehydration crystallization, etc. Freeze-drying in food industry, etc. Vacuum drying in pharmaceutical industry, etc. Polyester chips of light textile industry; High – altitude simulation test such as the vacuum system medium.


Working principle of circulating water cooling device of vacuum unit:

Use a pump to pump water from the storage tank all the way to the sprinkler and all the way to the unit’s cooling water inlet.

Water in a spray the perforated plate effect hundred holes, many of the water to form a vertical downward. The water to the fan, under the action of surface evaporation and cooling, cooling and then back to the water storage tank. The distribution of holes on perforated plate decide the position of water column, let the perforated plate on the uniform distribution of holes, in order to make good contact with air water column, published form as large as possible yan noodles, so as to achieve the goal of water cooling.

Considering the degree of vacuum unit discharge of water falling off, with the air temperature difference is bigger, so the design of the first level of the use of air forced cooling, let vacuum unit discharge of water through the radiator, radiator, after the fan by cool wind blowing through the water to the radiator, so that the diffusion pump discharge hot water cooling, and then back to the water storage tank, in the cooling water flow in the diffusion pump can be directly observed in the device.
