operational principle
The PY series semi fixed (portable) foam fire extinguishing device produced by Shandong Dongyue Crane Fire Fighting Equipment Manufacturing Co., Ltd. is connected with the fire hose at both ends of the pipeline proportional mixer and the pressure water source when extinguishing fire. When water with a pressure not less than 0.6MPa flows through the nozzle of the proportional mixer at a high speed, due to the diffusion effect of the lateral movement of the jet particle, a vacuum (negative pressure) is formed in the chamber of the proportional mixer, so the foam liquid in the foam liquid storage tank enters the mixer through the suction pipe under atmospheric pressure, mixes with the pressure water, and finally reaches a certain proportion of the mixed liquid, which is produced through the foam gun and foam The fire extinguisher sprays foam to extinguish the fire. Its operation is fast, simple, and reliable. Used to extinguish Class A, B, and C non water-soluble liquid fires. It is widely used in municipal residential areas, factories and mining enterprises, oil depots, chemical departments, heat treatment workshops, gas stations and other places.
Product Description
The composition of semi-fixed (portable) foam fire extinguishing device:
PY semi-fixed (portable) foam fire extinguishing device is also called a foam truck and a cart-type foam fire extinguishing device. It is mainly composed of a foam liquid storage tank, a spray gun, a proportional mixer, a water belt, and a cart chassis; it is a new type of mobile Foam fire extinguishing device is quick, easy to operate and highly reliable. Used to extinguish Class A, B, and C non-water-soluble liquid fires. It is widely used in municipal residential areas, factories and mines, oil depots, chemical industry departments, heat treatment workshops, gas stations and other places.
