Electrical equipment in the computer room should be explosion-proof. When electrical maintenance is stopped, the power supply must be cut off.
2 Emergency valves should be installed at the gas pipeline intake room in order to cut off the gas source quickly in case of emergency in the workshop. The valves should be close to the operating room.
In order to install gas concentration alarm in the engine room, it is better to install two gas concentration alarms in the diagonal part of the engine room。 When the environmental concentration is within the range of explosion and poisoning concentration, forced ventilation is necessary to start the unit before reducing the concentration。
3。 Gas Pipeline Request for Gas Generator Sets
3.1 Gas pipeline shall adopt steel pipe, the pipe wall shall not be too thin, and the joint shall be sealed firmly. After the gas pipeline connection is completed, gas detector or soap water shall be used to detect the leakage of pipeline, especially at the joint of flange and valve.
3.2 Valves should be inspected regularly. There should be no gas leakage, damage and other phenomena. There should be no accumulation around the valves which hinders the operation of the valves. Valves should stop opening and closing operations and maintain themselves regularly. Valves that cannot be opened or closed properly should be repaired or replaced in time.
3.3 Rubber pipes in gas pipelines should be regularly replaced, and the use of outdated aged rubber pipes is strictly prohibited.
3.4 When the units and gas pipelines stop operation, maintenance and emergency repair, they must firmly cut off the gas source and exhaust the internal gas. No gas supply shall be restored to the gas equipment until the cause of the accident has been ascertained and necessary safety measures have been taken. When stopping maintenance and overhaul, explosion-proof measures should be taken or explosion-proof tools should be used. It is strictly forbidden to stop knocking operation with tools such as iron.
3.5 The emergency repair of gas leakage should stop after cutting off the gas source. When the leakage has been extinguished, measures should be taken to control the fire situation before cutting off the gas source. Negative pressure in the pipeline should be strictly prohibited.
