We are growing into a global company through continuous research.
It is necessary to understand the safety operation procedures of fog gun machine in use, so as to avoid adverse consequences caused by operation errors.
The safety operation procedures of fog gun machine are as follows:
1、 When the air supply pressure exceeds the rated service pressure of the tool, the pressure regulating valve shall be used. The operator and maintainer shall not wear wide clothes according to the regulations. It is strictly prohibited to point the air outlet of the manual wrench to people.
2、 The air supply hose shall be pressure resistant and have oil resistant inner surface and wear-resistant outer surface, and the hose shall be firmly fixed on the joint. It shall be used away from oil, hot surfaces and chemical places.
3、 The test run of the fog gun after maintenance shall be carried out in a protected and enclosed area, and only short-term (less than 1 minute) high-speed test run is allowed; Do not idle at high speed for a long time at any time.
4、 Before starting the fog gun machine, first check that the tools and their protective devices are intact, clamped normally, without looseness, and the tools are free of cracks; Also check that the gas circuit is well sealed, the safety device at the pressure source is intact, and the air duct connection is firm.
5、 When the fog gun is started, the test run shall be carried out first. After starting, it shall be stable without violent vibration, and the work shall be carried out after dynamic inspection.
6、 If abnormal sound is found during operation, stop the machine for inspection, find out the cause and eliminate it before continuing the operation.
7、 A specially assigned person shall be responsible for inspection, storage and regular maintenance of the fog gun machine.
8、 No. 46 anti-wear hydraulic oil is used for the hydraulic system of fog gun machine. The hydraulic oil shall be replaced once every half a year. When replacing, open the oil nozzle, drain all raw liquid, clean the oil tank, add new oil to below the full scale mark of the oil tank (about 25L), and adjust the pressure of the overflow valve to 4.5mpa-8mpa.
9、 In cold areas such as northeast China, 32 anti-wear hydraulic oil should be replaced in winter. If the hydraulic system of the fog gun machine is emulsified by water, it shall be drained immediately, the system shall be cleaned and replaced with new oil.
