Be careful when disassembling the mechanical seal, and it is strictly forbidden to use a hand hammer and a flat shovel so as to avoid damage to the sealing element.
The standard parts of vacuum flange (vacuum gauge) are mainly accessories used in vacuum system with different connection methods. The most common are CF flanges, KF flanges and ISO flanges.
whether it is airplanes, rockets, tanks, submarines, drilling, mining, trains, ships, or daily life, pumps are needed everywhere, and pumps are running everywhere.
System requirements for vacuum degree. Pressure range during normal operation of the system. The type, composition, impurity situation of the air and the pollution restriction requirements during system operation.
Vacuum pump can basically be divided into two types, gas capture pump and gas transmission pump. It's widely used in metallurgy, chemical, food, electronic coating etc.
The fan speed is low, the air pressure is small, and the air volume is small. The motor has a large power, a large working current, and a large amount of heat. The number of fan blades is small, and the amount of air generated is small.
In order to prevent the vacuum pump oil from returning to the pumped container when the pump is stopped, a built-in anti-oil return device is very important.
Sealing Methods: Minimize the number of places where seals are set. Blocking and isolation. Elicit or inject. Increase leakage resistance. Add work elements in the channel. A variety of sealing method combinations.
