The PY portable foam fire extinguishing device PY8/300-PY8/500 primarily consists of an atmospheric foam liquid storage tank, foam generator, in-line proportioner, fire hoses, and a trolley frame. It can be used by connecting the device's own fire hoses to water supply equipment such as fire hydrants and can be positioned advantageously for firefighting. As a supplement to fixed fire extinguishing systems, it can provide fire protection for multiple devices within a protected area. Suitable types of foam liquid can be selected as needed to extinguish various liquid fires. Portable foam fire extinguishing devices are widely used in oil depots, petrochemical plants, oil pump rooms, gas stations, and other locations. 

Foam Tank Trolley-Type Fire Extinguishing Device PY8/300  Working Principle: When firefighting is required, connect the foam generator and proportioner with fire hoses. The inlet end of the proportioner is connected to a fire hose and supplied with pressurized water. When the pressurized water flows at high speed through the nozzle of the proportioner, a negative pressure is created inside the proportioner chamber. The foam liquid in the storage tank is drawn into the proportioner through the suction pipe under atmospheric pressure, mixing with the pressurized water in a predetermined ratio to form a foam solution. When the pressurized foam solution passes through the foam generator, air is吸入, causing the foam solution to foam and spray, covering the surface of the burning liquid to extinguish the fire.

Our factory has been producing firefighting products for 20 years, with above-ground and underground fire hydrant products achieving high quality and standards for nearly a decade. All finished fire hydrants leaving the factory pass quality inspections!! We welcome friends from all sectors to visit our company for tours, guidance, and business discussions.
