Liquid oxygen is a strong combustion supporting substance, and its pressure is very high during gasification and bottle filling, so special safety measures should be taken during system configuration:
1) The liquid inlet pipe and gas return pipe connected between the pump and the storage tank shall be equipped with emergency shut-off valves, which shall be interlocked with the pump, so that in case of an accident, the liquid and gas sources can be cut off from a long distance in time, and the liquid pump can be stopped in an emergency;
2) The outlet of liquid oxygen pump shall be equipped with overpressure alarm and interlock pump stop device;
3) The oxygen header behind the high-pressure vaporizer shall be equipped with temperature indication and temperature alarm devices to prevent liquid oxygen from entering the cylinder and causing accidents;
4) Steel plates with a thickness of more than 5mm shall be set around the liquid oxygen pump to form a protective separation wall;
5) The shaft seal of liquid oxygen pump shall be equipped with nitrogen protection gas pipe;
6) The filling manifold shall be filled with a new type of metal hose with anti misplacement connector, and it is strictly prohibited to use hoses made of other materials. High pressure valves and pipelines shall be provided with O-ring made of copper wire;
7) The busbar shall be connected with an overpressure audible and visual alarm device;
8) The number of bottles filled in the manifold is determined by the filling volume and filling speed of the pump to prevent excessive flow rate.
DEAR Air Separation is familiar with the principle of equipment. Professional training instructors escort customers. How to let customers get familiar with the equipment as soon as possible is crucial to ensure correct and reasonable operation.
