Liquid Ring Vacuum Pumps of in Paper Making Industry
Advantages of liquid ring vacuum pumps for paper making industryThe vacuum system as the biggest auxiliary system in the paper making workshop is used to dewater and deliver pulp and clean felts. The pulp in the sheets and the pressure become dryer in the vacuum system, so consumption of vapour mil decrease. Series 2BE vacuum pump is the core products of EVP Pumps
1. The considerate design and configuration for the whole system improves its reliability.
2. Energy- saving. Efficiency is 10%-20% higher.
3. Lower noise — less than 85 dB.
4. Reduce 95% — 98% water consumption by adapting theinternal circulation system,
5. The pump can operate in two area coverage and the pressure difference can reach 80 KPa.
6. Reasonable improvement of the impeller structure effectively avoid accumulation in pump.
7. The inspection port allows easy access to pump internals for inspection and maintenance.
Application
High efficient pre-separator and filtrate pump
The pre-separator designed for paper making industry as part of the waste heal recovery system is reliable and easy to operate and maintain.
Gasses, water, fabric, impurities coming from the paper machine are completely separated by the pre-separator (the testing result indicates that the separating rate is more than 98% ). This is very important to the recirculation of the sealing water.
● highest separation rate
● less installation area
● easy maintenance
● no liquid level control
Special design of the filtrate pump makes it possible to work at the vacuum condition. The pump can be easily mounted on the vessel by flange without taking much installation space. Different angular orientation of mounting is permissible, so it is easy to maintain.
Vacuum system with top mounted separator
Vacuum system with top mounted separator
Adopts the upper separator, can effectively carry out steam and water separation, the separated water is sent through the booster pump to the cooling tower, and returns to seal water supplement tank after cooling.
Vacuum system with underground canal
Underground canal is adapted to exhaust gasses to furthest decrease noise of airflow,and the discharged gasses and water can be separated completely.And the separated water is transported to the cooling tower via booster pump,and then back to the sealing water tank after being cooled.
