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...

Everyone in modern society is enjoying the convenience brought to us by vacuum technology. For example: the secret of the heat preservation of the thermos is that there is a vacuum space in the wall of the bottle, which reduces heat conduction to maintain the temperature in the pot; fluorescent l...

Industry analysis: Using waste oil or gutter oil as raw materials and adopting appropriate processes to produce methyl ester of oil and palmitate has become very mature due to its low cost, mature technology, and wide market. In this production process, the dehydration and distillation of the vac...

(1) The medium conveyed by the vacuum pump is pressed too tightly; Solution: Loosen the packing gland of the water ring pump. (2) The speed of the vacuum pump is too high; Solution: Reduce the speed of the water ring pump. (3) The power of the motor supporting the vacuum pump is too low; Solution...
