vacuum system for the Paper Industry

Vacuum system is very important for papermaking. They contribute to sheet forming and dehydration, press performance, felt conditioning and general machine efficiency. The vacuum system consists of several subsystems for vacuum control, air/water separation and vacuum pump sealing water management.

The most common vacuum pump equipment in papermaking vacuum system is liquid ring vacuum pump. By introducing its development history, working principle, structural characteristics and the application characteristics of rotary vane vacuum pump in paper mills, this paper summarizes its advantages, hoping to provide references for the relevant technical personnel in the paper industry in choosing vacuum generating equipment.

At present, the vacuum equipment used in paper industry, liquid ring vacuum pump (compressor) is a product with low energy consumption and high efficiency. Therefore, liquid ring vacuum pump is the most commonly used equipment in paper vacuum system, which is well known to the technical personnel of paper industry.

Among all kinds of vacuum pumps, liquid ring vacuum pump is the most widely used one in the paper mill field, and it is also one of the most important types of vacuum pumps with the fastest development of functional structure.

With the continuous improvement of the technological performance of liquid ring vacuum pump, industrial robots, microelectronics, computers, intelligent and image sensing technology are widely used in the production system of pump industry. In the future market, the research and manufacture of liquid ring vacuum pump will develop in the direction of high speed, multi-function and intelligent control. Automation and integration will become the future development of liquid ring vacuum pump. Direction.

Modern paper machines use vacuum to help paper dehydration, so the vacuum system is an important part of a paper machine. There are several vacuum elements on a paper machine that require different vacuum degrees and need to be connected to the vacuum system. If the liquid ring vacuum pump is used to build the vacuum system, some close points of vacuum degree are often combined, and several liquid ring vacuum pumps are selected to build the vacuum system according to different vacuum degree. The use of vacuum pumps is independent, and there will be no interference or chain reaction between different vacuum pumps. Under the existing technical conditions, the comprehensive performance of liquid ring vacuum pump is better than others, so the application of liquid ring vacuum pump in paper mills occupies a dominant position.
