The connections between various components of the vacuum pump body need to be sealed. Rubber has good elasticity, making it a good transitional sealing material for detachable connectors. The properties of commonly used rubber include the following categories: 1: Natural rubber. Good elasticity, ...

The customer industry is biopharmaceuticals and cosmetics, and the vacuum equipment is used for vacuum extraction in concentration tanks. A single water ring vacuum pump is used. Due to the unstable vacuum degree and the requirement of a vacuum degree of ≥ -0.095kpa, the existing vacuum equipment...

In the tobacco industry, vacuum pumps are usually used in the following applications: Tobacco drying: vacuum pump can be used for vacuum extraction during tobacco drying. By placing tobacco leaves in vacuum environment, moisture can be removed quickly, the drying process of tobacco leaves can be...

In order to recover low-pressure natural gas generated by the secondary separator and reduce torch gas emissions, a liquid ring compressor was first used for low-pressure flash gas recovery and reuse on an offshore platform. Compared with conventional screw and reciprocating compressors, the liqu...

Oil sealed mechanical pumps are not suitable for discharging gases containing a large amount of water vapor. Water vapor will condense saltwater droplets during the compression process and mix with pump oil to form a suspension. This not only reduces vacuum, but also causes rust and damage to the...

To ensure the normal operation of production, reduce the repair probability of vacuum pumps, and extend their service life, the following precautions should be taken when using vacuum pumps in winter: 1. Try to increase the indoor temperature as much as possible. In the cold north, the heating c...

In chemical production, in order to reduce reaction temperature, increase evaporation capacity, and transport materials, the device needs to be in a negative pressure state. The so-called negative pressure refers to the concept of relative to normal pressure, generally referring to a pressure low...

1. The advantages and disadvantages of using the irrigation method to search for vacuum systems that are not tight The vacuum system contains a large number of equipment and systems, and there are many dynamic and static sealing points connected. It is difficult to detect the leakage point in the...

1. Stripping Phenomena: The running surface peels off and shows a noticeable convex concave shape after peeling Reason: 1) Excessive load and improper use 2) Poor installation 3) Poor accuracy of shaft or bearing box 4) Clearance too small 5) Foreign object invasion 6) Rust occurs 7) Hardness dec...

The models are ZJP-1200 and ZJP-600 Roots pump sets, and each time engine oil is added, it must be stopped, which affects production. From the structure, it can be seen that the synchronous guide gearbox and the Roots pump chamber are sealed through internal oil seals. After the operation of the...
