Product Description

- Commodity name: High-expansion foam generator PF4
- Commodity ID: PF4
- 品牌: Hydraulic
1. Overview

The high-expansion foam generator produced by hydraulic fire protection, also known as air foam generator, foam generator, and foam generator, is a fire extinguishing equipment that is fixedly installed on the oil tank to generate and spray air foam. When the foam mixed flow supplied by the fixed fire pump of the foam fire truck passes through the generator through the conveying pipeline, air foam is formed to extinguish the oil fire.

At the time of supply, the nozzle set only includes flanges, gaskets, fasteners, etc., while the nozzle and elbow are purchased and processed by the user to form the nozzle set. The generator should be installed horizontally on the upper part of the tank wall, not on the top of the tank. When the cover plate is installed, it is not suitable for side installation. When used in external floating roof tanks, it should be installed on the foam shroud at the top of the tank.

When installing the generator, the opening in the tank wall should ensure that there is enough space in the upper part of the tank, and the liquid level of the stored liquid should be lower than the inlet of the generator, and should be below the storage liquid level line, so as not to affect the foam quality and foam formation, and prevent the liquid from flowing out of the generator port.

2. technical parameters

There are generally four types of foam generators: PC-4,PC-8,PC-16, and PC-24.

1. Specific technical parameters are as follows:

  ① Model PC-4: When the working pressure is 0.5MPa, the mixed liquid is 4 liters/second, and the foam generation amount is 25 liters

  ② Model PC-8: When the working pressure is 0.5MPa, the mixed liquid is 8 liters/second, and the foam generation amount is 50 liters

  ③ Model PC-16: When the working pressure is 0.5MPa, the mixed liquid is 16 liters/second, and the foam generation amount is 100 liters

  ④ Model PC-24: When the working pressure is 0.5MPa, the mixed liquid is 24 liters/second, and the foam generation amount is 150 liters

2. Working pressure range: 0.2-0.5MPa

3. The glass sheet is broken under a pressure of 0.1-0.2MPa.

3. structure principle

The hydraulic fire foam generator/generator is mainly composed of three parts: shell group, foam nozzle group and guide plate group.

When the foam mixture flows through the nozzle of the generator, a diffused atomized jet is formed, and negative pressure is generated around it, thereby inhaling a large amount of air to form air foam. The air foam is input into the storage tank through the foam nozzle and the guide plate, and flows along the tank wall., Smoothly covered on the combustion liquid surface.

The air foam generator consists of the following parts: 1. Sealing glass 2, glass pressure ring 3, nozzle 4, filter screen 5, cover plate 6, shell 7, foam nozzle group 8, shell group 9, and guide plate group

4. product use

It is fixed in the building, and there is a pipeline on the wall to connect with the pump station to supply water and foam fire extinguishing. Can be used to protect commercial buildings, hotels, restaurants, cabin hangars, engine test workshops, car depots, oil depots, alcohol workshops, oil pump rooms, chemical workshops, atomic power plants, computer rooms

5. instructions for use

1. The inlet calibration working pressure of the air foam generator is 0.5Mpa, and it can also be used within the pressure range of 0.3-0.5Mpa, but the mixing amount and foam amount change accordingly.

2. The water pump shall be equipped with PH32 and PH64 air foam mixers to deliver air foam liquid in proportion.

3. This generator is equipped with 3% type and 6% type ordinary air foam liquid.

4. In order to prevent the gas in the flammable liquid storage tank from evaporating and leaking, the sealing glass must be installed at the outlet end of the shell. The glass is engraved with fragile cracks on one side, and the mixed liquid flow pressure can be broken when it is 0.1-0.2Mpa. The frangible crack should be installed with one side facing the direction of the discharge port.

5. The guide plate is installed on the inner wall of the storage tank to ensure that the foam tank wall drops and smoothly covers the burning liquid surface to improve the fire extinguishing effect.

6. The pore size of the inlet pipe of the air foam generator shall not be less than the size specified in D.

6. installation and maintenance

1. There is a product label on the air foam generator, indicating the product name, model, specification, manufacturing date and factory name. Before installation, the foam nozzle group shall be prepared by the user according to the product model with reference to the dimensions listed in Figure 2 and Table 3.

2. The position and size of the opening on the tank wall (refer to the figure below)



3. Assemble the guide plate on the inner wall of the storage tank first, and then install the foam nozzle group and the shell group. The cover plate should be above.

4. After installation, conduct a foam injection test to observe whether the injection foam is normal, whether the water supply pressure of the water pump and the inlet pressure of the generator meet the requirements; whether there is any leakage in the pipeline, etc., and finally install the sealing glass.

5. The entire pipeline of the air foam generator must be unblocked, and it is necessary to check whether there is blockage. Whether the sealing glass is intact.

6. In order to avoid and reduce the damage to the pipeline when the storage tank wall is deformed, it is best to install a metal hose of the same diameter in the inlet pipeline of the producer.
