ã€Asia Fluid Network News】 Steam jet vacuum pump is a simple structure, stable performance of the vacuum equipment. Its working principle is very important for studying the steam jet vacuum pump. As the technology advances, its working principle is more and more suitable for the present industrial development. The following describes the working principle and structure of the steam jet vacuum pump. Jet vacuum pump works: Steam jet vacuum pump has a certain pressure of the work of the vacuum pump equipment, steam through the Laval nozzle, reduced pressure growth, the potential energy of steam into kinetic energy and the supersonic spray into the mixing chamber, In order to reduce the pumping load of the rear-stage pump, a condenser is arranged, convection is conducted through two mediums with a certain temperature difference, and heat is carried out Exchange, to achieve the purpose of condensing high temperature medium, discharged to atmospheric pressure. Working principle as shown below: Steam jet vacuum pump working principle diagram of the unit: 1. The first level of the pump water vapor jet vacuum pump connected to the production equipment pumping and its gas, steam or gas and compressed in the pump to about 10mmhg . 2. The pump of the second stage steam jet vacuum pump to continue to compress the above working medium to 70mmhg then row of gas leads to the tube condenser condensation. Condensed liquid into the lower third water ring pump suction, compressed to the atmosphere. Block diagram of the unit To sum up the principle of the steam jet vacuum pump is relatively simple, the user can understand its working principle to select the products they need, the producer can improve the work of its lack of products and improve product competitiveness. In general, with the continuous improvement of China's industrial level, how to improve the competitiveness of products and the market share is very necessary. Steam jet vacuum pump after years of development, already has a very solid foundation, I believe that as the market demand continues to increase, steam jet vacuum pump will have a more brilliant future.
