1 简介YGFZ500移动式干粉灭火装置是介于干粉消防车和干粉固定装置之间的一种新型消防装备。 Mobile dry powder fire extinguishing device 1 Introduction YGFZ500 mobile dry powder fire extinguishing device is a new type of fire fighting equipment between dry powder fire truck and dry powder fixed device. It combines the advantages of its two types of fire fighting equipment, and carries out scientific innovations on the more cumbersome operation of the two, making it more concise in operation and more reliable in use. This device is mainly used in oil fields, oil depots, gas stations, hangars, large warehouses, civil and military airports, and is particularly suitable for the construction and maintenance sites of petrochemical companies and oil and gas pipelines; and fixed targets with hidden fire risks. 2 Working principle 2.1 Working principle of dry powder system With nitrogen as the power, the energy conversion of nitrogen and dry powder is carried out in the dry powder tank, that is, the pressure potential energy of nitrogen is converted into the kinetic energy of dry powder, and it is launched through a dry powder launching device (dry powder gun or dry powder gun). 3 Use the operation method. Correct operation and reasonable use can not only make the equipment quickly enter the battle, but also successfully complete the fire extinguishing task. And it can guarantee the maximum possible function and extend the service life, so it must be paid attention to. Attention !!! When performing all the following tasks, park the vehicle and lower the screw support. 3.1 Inspection 3.1.1 Check the pressure of the nitrogen cylinder 126.96.36.199 Remove the joint connected to the valve of the nitrogen cylinder; 188.8.131.52 Install the nitrogen cylinder pressure check table (accessory) 184.108.40.206 Open the nitrogen cylinder valve, the pressure gauge shows the nitrogen cylinder Pressure; if the pressure is lower than 12MPa, the nitrogen bottle should be inflated immediately. 220.127.116.11 Confirm that the nitrogen cylinder valve is closed, remove the connecting tube, and test and check the cylinder pressure. 18.104.22.168 Reconnect the associated connectors. 3.1.2 Check whether the dry powder gun 13 (Figure 2) is flexible to rotate up, down, left and right. 3.1.3 Check whether the powder ball valve 12 (Figure 2) of the dry powder gun is in the closed position. 3.1.4 Check whether the gun purge valve, tank discharge residual gas valve 11 (Figure 2), gun purge control valve 9 (Figure 2), and dry powder gun powder control valve 7 (Figure 2) are in the closed position. 3.2 Inflating the dry powder tank by opening the valve of the nitrogen bottle, the filling of the dry powder tank is completed. 3.3 The operation method of the dry powder gun 4.3.1 Inflating the tank according to the provisions of 4.2. 3.3.2 Lifting the positioning constraint, the dry powder can rotate in the range of horizontal 180 ° and vertical -15 ° ~ + 45 °. 3.3.3 Turn the dry powder gun to the target. 3.3.4 The dry powder tank pressure is 1.4 ～ 1.6MPa. 3.3.5 Open the shot powder ball valve to spray dry powder. 3.4 Operation method of dry powder launching gun 3.4.1 Inflate the tank according to 43.2. 3.4.2 Unroll the hose of the coiler and smooth it. 3.4.3 Open the powder control valve of the dry powder gun. 3.4.4 Open the valve on the dry powder firing gun to spray dry powder. 3.5 Loading powder 3.5.1 First check whether the flange bolts on the bottom of the dry powder tank are loose, whether the rubber seals are intact and placed correctly. If the above phenomenon occurs, first replace the rubber seal or place it correctly, and tighten the bolts evenly. 3.5.2 Open Plus ...
1． Mobile high magnification foam generator Brief introduction: PF4 mobile hydraulic high multiple foam generator is composed of 400L mobile foam liquid tank, proportional mixer, high multiple generator and so on. The pressure water supplied by the water pump passes through the proportional mixer to form a mixed liquid at a ratio of 3% or 6%, and is sent to the generator under pressure. When the pressure mixed liquid passes through the nozzle and is impacted, the fan is quickly rotated to generate air flow and blow the mixed liquid. The foam group is generated to cover the fire point, cool down, and extinguish the oxygen. It can also play a role in protecting the safety of on-site personnel. It can also unscrew the hose connection buckle connected to the high-power generator and connect the foam gun for distance fire suppression. 2. Characteristics: (1). This type of high hydraulic foam generator is small in size, light in weight and large in foaming capacity. (2). This type of generator can be installed according to the installation environment, or it can be moved to any area to directly extinguish the protective foam. (3). People who can't escape in time in the fire extinguishing zone can be covered in the foam group, just cover the nose with their hands to let the foam burst at the finger joints, and the oxygen in it is enough for breathing, because the foam is transparent Doors and windows can be seen in the foam group, and slowly walk out to leave the fire zone. (4). All items and electrical equipment in the protected area will be without loss. Because the water consumption of the foam group is very small, the foam is covered fire extinguishing. After the fire extinguishing, it can be restored by blowing it off with a fan. 3. Applicable places and scope: PF4 hydraulic high multiple foam generator is suitable for warehouses, garages, library tubes, liquefied gas stations, archives, chemical workshops, passenger and freight ships, shopping malls, restaurants, computer microcomputer rooms, large coal yards, Large garbage dump. 4. Usage: PF4 hydraulic high multiple foam generator, in addition to being a full-flooded fixed fire extinguisher in a large area of limited space, can also be used in the following places: A. Vehicle-mounted foam will be brought by the fire truck to the fire site. The foam generator was placed at the entrance of the fire zone to foam the fire. Control the flow-type fire zone. When a dangerous oil and other dangerous flammable chemical products explode, a flowing oil fire will be generated. To control its spread, this type of generator can be installed on the dike to generate a large number of foam groups to surround the fire flow and prevent its large area. Flowing and spreading causes the connection burning in the nearby dangerous goods area.
