Suspended heptafluoropropane is an application form of HFC-227ea extinguishing agents. Because of its small size, convenience, easy installation, and fast fire extinguishing efficiency, it has been widely recognized in the market. However, how to maintain and use suspended heptafluoropropane is a problem. Today, we will discuss in detail how to maintain the suspended heptafluoropropane.

Suspended heptafluoropropane is divided into three types of electric control, temperature control, and electric temperature dual control. In the process of maintenance and maintenance, it must be strictly implemented in accordance with the relevant regulations of GB50263-2007 "Gas Fire Extinguishing System Construction".

First, maintenance and maintenance during daily operation

1. Keep the protection area and control room clean, dry and well ventilated.
2. The surface of fire extinguishing device and alarm fire extinguishing controller is clean and dust-free.
3. The safety pin and lead seal of the drive device should be intact and undamaged.
4. Check the nameplate and warning plate of the device, it is non-destructive, clean and visible.

Second, quarterly maintenance and maintenance

1. Check the pressure of each fire extinguishing agent storage bottle. The pressure indication value of the pressure gauge should normally be in the green area.
2. Perform visual inspection of all device components such as fire extinguishing agent storage bottle, container valve, electromagnetic drive device, nozzle, signal feedback device, pressure gauge, etc. No collision, deformation or other mechanical damage, no rust on the surface, protective coating intact, nameplate Should be clear, protective cover, lead seal and safety signs should be complete.
3. Carry out visual inspection of all device components such as fire extinguishing agent storage bottles, temperature-sensitive release components, pressure gauges and so on.

Third, annual maintenance and maintenance

1. The opening situation of the protection area, the purpose of the protection area and the type, quantity, and distribution of combustible materials meet the design requirements.
2. Perform a comprehensive inspection of the fire extinguishing device: the components are connected reliably and there is no looseness. The fire extinguishing agent delivery pipe and the nozzle hole are not blocked, and the device must be cleaned.
3. Carry out alarm and start simulation tests on the alarm fire extinguishing controller, and the signals and actions of fire detection, alarm and fire extinguishing control are all normal. Check the automatic and manual (including emergency start, emergency stop) control mode of the drive device, and the device is operating normally.

Remember: the electromagnetic drive device should be removed from the container valve during the simulation experiment.

4. Fluorinated Solvent Wholesaleremoves the signal feedback device to check manually push the piston (simulating fire extinguishing agent discharge pressure), the discharge indicator light should be on, the signal should be normal feedback and can be reset manually.
