Air respirator is a common kind of security product, which belongs to isolated respiratory safety protection products and has a high level of safety protection. It is mainly used in various harsh environments or rescue activities. Its use is directly related to the health and safety of workers. If the air respirator fails during use, the harm to the user is extremely great. One of the more common failures in the use of air breathing apparatus is gas leakage. How is the gas leak caused? Below we have a detailed understanding of the next.
Air leakage from air respirators mainly includes two aspects: one is the mask gas leakage and the other is the system gas leakage.
(1) Mask gas leakage. 1. The improper headband looseness causes the gas to leak from the gap between the mask and the face. Solution: Reapply and adjust the headband of the air respirator mask.
2. Inadequate connection between the air respirator mask and the air supply valve leads to gas leaking out of this gap. Solution: Remove the air supply valve, check the O-ring at the air supply valve connection, and replace the O-ring if damaged.
(2) System leakage 1. Leakage at the interface of the air respirator's pressure reducing valve and cylinder valve or a problem at the connection between the medium-pressure conduit and the pressure relief valve leads to gas leakage. Solution: Check whether there is foreign matter in the plane of the connection and in the groove. If there is foreign matter, it should be removed. Check if the O-ring is in good condition. If it is damaged, it should be replaced with a new O-ring.
2, the air respirator quick joint leakage, solution: check the supply valve on the scratch, deformation and other conditions occur, if there is deformation or scratches should be replaced air respirator valve, if the plug is intact, The quick connector socket is defective and the pressure relief valve medium pressure tube should be replaced.
3, pressure gauges and pressure gauges or pressure reducing valve problems lead to gas leakage, we should find a professional person to repair.
The above are the causes and solutions for air leakage from air respirator. I hope to help you.
