Testing Machines for Fire Fighting Equipment

Burst Pressure and Pressure Alternation Test Equipment for Portable Fire Extinguisher is used for pressure testing, burst testing, and pressure alternation testing of water-based, dry powder, carbon dioxide and clean gas extinguishers. Air Driven liquid pump is used as the power source for pressure-holding testing and burst testing, which is controlled by computer. The pressure is stable and the burst pressure is accurately collected. Electric proportional control is adopted for pressure alternating testing, with pressure accuracy greater than 0.5% and time accuracy greater than 0.1s. The selection of proportional booster ensures the good long-term cloud turning performance of the equipment.
