How to start the fire fighting pump?

Fire fighting pumps are used to pump all kinds of liquids. They are ideal pumps and fire protection systems for creating leak-free and pollution-free civilized workshops and civilized factories. They are often installed on fire trucks, fixed fire extinguishing systems or other firefighting facilities for transportation A special pump for liquid fire extinguishing agents such as water or foam solutions. fire fighting pumps are widely used in environmental protection, water treatment, fire protection and other departments.

How to start the fire fighting pump

The starting relationship between the fire control room and the fire hydrant action button is related to the starting form of the fire hydrant pump. The starting methods of hydrant pumps are generally divided into two types. The first starting method is the bus control mode. The start of the hydrant action button can send the required start signal to the fire control through the linkage interface module located next to the hydrant The room console, and then output the digital contact that enables the fire hydrant to start. The second starting method is to directly output the switch contact of the fire hydrant action button to the fire hydrant pump start box. These two starting methods can be used in actual design. The former method saves wiring, but under the bus system, address coding of the hydrant linkage module is needed to achieve the purpose of monitoring a large number of hydrants. The latter starting method is simple and reliable, but it also needs to return the fire hydrant action signal to the fire control room. The designer can choose according to the actual project scale in the specific design. For the large-scale project and the complex construction form, the former start-up method can be used, and for the small scale, the latter start-up method can be used.

The self-starting of the portable fire fighting pump is to break the glass ball of the pipe network nozzle of each protection zone at high temperature, causing the water flow of the pipe network, thereby linking the pressure switch action of the alarm valve to achieve the purpose of starting the spray pump automatically. Through the water flow indicator linkage module or alarm valve pressure switch lead to the control room, the fire control room can accurately reflect its action signal, and the control room should be able to directly control the start and stop of the spray pump.

Pump room management

The vertical fire fighting pump room is a key part to provide water for fire fighting and is an important part directly related to property safety. To manage the pump room and clarify responsibilities, the following system is formulated:

1. All mechanical and electrical equipment in the pump room, underground water tank, and fire fighting system are monitored by the equipment and firefighters. Regular inspection, maintenance, maintenance, cleaning, and cleaning are done, and records are made. Problems that cannot be solved are reported to the rectification in time.

2.The mechanical and electrical equipment in the pump room is the responsibility of the equipment and firefighters, other personnel have to operate, and unrelated personnel must not enter the pump room.

3. Under normal operation of all equipment in the pump room, the switch should be set in the automatic position, and all operation signs are simple and clear.

4. fire fighting pumps and spray pumps are inspected every day, and an "automatic and manual" operation inspection is carried out, and a comprehensive maintenance is conducted every quarter.

5.The power supply of the control circuit of the pump room should be checked every month to check whether the standby water pump can automatically run in the case of the failure of the host.

6.The sanitation of the sewage tank is often cleaned, and the pumps and pipelines are often maintained.

Selection knowledge

The selection of fire fighting pumps should be considered in terms of liquid delivery, device head, liquid properties, pipeline layout, and operating conditions according to the process flow of fire fighting pump application engineering, water supply and drainage requirements.

The pumps used in fire fighting systems are divided into the following types:

The fire sprinkler pump, fire hydrant pump, fire stabilizing pump, and fire booster pump are determined according to the actual conditions of use.

The types of pumps used in fire protection systems are similar, except that the head and flow are different.

Horizontal fire fighting pumps are mainly divided into vertical fire fighting pumps and horizontal fire fighting pumps. The flow rate of conveying liquid is one of the important performance data of fire fighting pump selection. The flow rate of conveying liquid is directly related to the production capacity of the entire device.
