2BW Low Noise Modular Condensing Water Ring Vacuum Pump

Availability:
Quantity:

Application scope:


The products are widely used in industries such as machinery, petroleum, chemical, papermaking, electronics, mining, metallurgy, medicine, sugar making, printing and dyeing, plastics, pesticides, brick and tile machinery, low-temperature equipment, food machinery, and other fields. The products are sold to various regions in China and are highly trusted and praised by users.

The main characteristics of closed circuit circulation system of water ring vacuum pump are as follows:


1. The unit is supplied as a complete set of equipment, including gas-liquid separator, heat exchanger, frame, internal pipeline and other accessories, which is more conducive to the installation of users and can greatly shorten the installation cycle of users.


2. The working liquid can be recycled with water or various chemical solvents, which greatly reduces the environmental pollution in the chemical industry.


3. If the extracted medium is used as the working liquid, the extracted medium can be recovered.


4. 2BW series closed-loop system needs to be designed according to the user's inlet condition, cooling water condition, exhaust port condition and so on, which belongs to non-standard product.

In general, water ring vacuum pumps typically discharge their working fluid directly, as illustrated in Figure 1 below:

  1. The water that is discharged by the water ring vacuum pump either enters a large circulating water tank or is directly released. This method of supplying and draining water is easy to connect and simple to use, and is commonly used in practical applications.

However, if the substance being extracted contains organic solvents and toxic materials, the use of the method shown in Figure 1 has the following drawbacks:

  1. When the water ring pump is pumping gas, the gas being pumped becomes mixed with the working fluid, causing the water being discharged from the outlet to contain some organic solvents and toxic substances. Since a large amount of water is discharged, this water discharge can greatly pollute the environment.

  2. Water that contains organic solvents and toxic substances will release harmful gases, further contributing to environmental pollution.

  3. The extracted organic solvent is difficult to recover and ends up being wasted.
