SF6 positive pressure air breathing apparatus leakage from where to find the cause?

SF6 positive pressure air respirator belongs to the barrier type respiratory protection supplies, is a kind of self-contained open air respirator, mainly used in fire fighting, chemical industry, ships, petroleum, smelting, factories and mines, etc., so that firefighters or rescue personnel can safely carry out fire fighting, rescue and relief work in the harsh environment full of smoke, gas, steam or hypoxia. Especially in the power SF6 switch station, when the explosion-proof film breaks or other large area of SF6 gas leakage, the self-contained air positive pressure breathing apparatus configured in the switch station is conducive to helping on-site personnel escape quickly or emergency repair. At the same time, it can be used in emergency situations such as fire.

SF6 positive pressure air respirator is one of the respiratory protective equipment commonly used in industrial production, which can help us resist various toxic and harmful substances in industrial production through the respiratory system to damage the human body. Air breathing apparatus is usually used in a hypoxic environment, if the attack may present the risk of poisoning and suffocation, so we must pay attention to the operation, if the problem is found, it should be dealt with as soon as possible. First of all, we should check where the leakage is present, resulting in three local leakage problems of the air breathing apparatus system: 1, the pressure reducer and the gas cylinder valve leakage, 2, the medium pressure pipe and the pressure reducer joint leakage, 3, the rapid joint leakage.

If there is leakage at the interface between the air breathing apparatus pressure reducer and the gas cylinder valve, then we should first check the "0" ring at the junction; If there is leakage at the junction between the pressure tube and the pressure reducer of the air breathing apparatus, the threaded joint should be unscrewed with a wrench and the gasket should be checked. If it is a rapid leakage of the air breathing apparatus joint, the first thing to check whether the plug is damaged, deformed, etc. If such a situation occurs, the air supply valve should be replaced immediately, and the replacement is also a leakage after the replacement, which is a leakage of the socket, replace the new medium pressure pipe.
