Many people don’t know how we should maintain and maintain the cabinet-type heptafluoropropane fire extinguishing device after purchasing it? So today Guangzhou Rongan Fire Protection will bring you an article about "Key Points of Maintenance and Maintenance of Cabinet-type Heptafluoropropane Fire Extinguishing Device".

In order to ensure the reliability of the cabinet-type heptafluoropropane fire extinguishing device, the user should establish a complete device inspection and maintenance system in accordance with regulations, formulate operating specifications, and have a dedicated person responsible for regular maintenance, inspection and record keeping of the device.

During the maintenance and care of the cabinet-type HFC-227ea, the relevant provisions of the "Gas Fire Extinguishing System Construction and Acceptance Specifications" must be strictly followed. The maintenance and care of the cabinet-type HFC-227ea is as follows:

1. The maintenance personnel must be trained by the company and be familiar with the structural principle, working performance, main technical parameters, operation procedures and structural principles of each component of the device.

2. Monthly maintenance and care

(1) The HFC-227ea fire extinguishing agent reserve of the device should be checked every month.

① When the pressure gauge indication value of the fire extinguishing agent storage bottle is within the green value range, it can be considered that the fire extinguishing agent reserve is normal; if the pressure gauge indication value of the fire extinguishing agent storage bottle is found to be lower than the green indication value range, the construction party should be contacted in time.

② As the ambient temperature changes, the pressure of the fire extinguishing agent storage bottle will change accordingly, which is a normal phenomenon. As long as the pressure gauge indication value on the fire extinguishing agent storage bottle is within the green indication range, it means that the storage bottle pressure is normal.

③Fire extinguishing agent filling should be done by professionals.

(2) Each component of the fire extinguishing device should be inspected monthly. If any fault or abnormality is found, it should be repaired in time.
