Portable Mobile Diesel Fire Pump Manufacturer

The diesel engine fire pump has compact structure, small size and beautiful appearance. Its vertical structure determines that the installation area is small, and its center of gravity coincides with the center of the pump foot, thus enhancing the running stability and service life of the pump. The horizontal direction simplifies the connection of the pipeline, the pump rotor has a small winding, stable operation, low vibration, low noise and long service life. Diesel engine fire pump is mainly used for pressurized water supply in fire protection system pipelines, and can also be used in industrial and urban water supply and drainage, high-rise building pressurized water supply, long-distance water supply, heating, bathroom, boiler cold and warm water circulation pressurized air conditioning refrigeration system water supply and equipment matching, etc. occasion.

The main heat dissipation methods of diesel engine fire pumps can be divided into two types: wind heat dissipation and water heat dissipation. According to the two heat dissipation principles, the water heat dissipation system dissipates heat evenly and has a good heat dissipation effect. The relative price is also relatively low, so most diesel fire pumps mainly use water for heat dissipation. Wind cooling is divided into two types: natural wind and forced wind. Natural wind is to use the airflow coming in from the machine during movement to directly cool the cylinder head, cylinder block and other parts; The airflow at the place increases the cooling rate and area. The principle of water heat dissipation is to use water or antifreeze as a cooling medium to take away the heat of the high-temperature parts of the diesel fire pump engine to ensure the normal working temperature of the engine.

    The diesel engine mobile pump truck is an intelligent control product, and the operation information is displayed in informational information. The running status display of diesel engine mobile pump truck includes: waiting, starting, fuel supply, starting, starting delay, idling delay, normal operation, cooling shutdown, emergency shutdown. The display of equipment operating parameters includes: water pump speed, water pump head, cooling temperature, lubricating oil pressure, water pump flow, running time, fuel stock, starting battery voltage and other parameters. Equipment protection settings include: overspeed, low speed, low oil pressure, high cooling temperature, low air temperature (below 4°C), low fuel level, low battery voltage, high battery voltage, uncalibrated speed signal, and water pump water pressure is too low and over Flow and other pre-alarms; no speed signal, overspeed, low speed, low oil pressure, high cooling temperature, start failure, shutdown failure, oil pressure sensor open/short circuit, water temperature sensor open/short circuit, speed sensor open/short circuit, water pump water pressure over Automatic alarm for low and over flow;

    When the diesel engine mobile pump truck is working, the diesel engine water pump relies on the high-speed rotating impeller, and the liquid obtains energy under the action of inertial centrifugal force to increase the pressure. Before the centrifugal pump works, the pump body and the inlet pipeline must be filled with liquid medium to prevent cavitation. When the impeller rotates rapidly, the blades make the medium rotate quickly, and the rotating medium flies out of the impeller under the action of centrifugal force. After the water in the pump is thrown out, the central part of the impeller forms a vacuum area. While continuously inhaling liquid, it continuously gives the inhaled liquid a certain amount of energy to discharge the liquid. The diesel engine water pump just works continuously like this.

    The role of the mobile pump truck:

    As an important supplement to fixed pumping stations, mobile pumping stations can be used in flood control and drainage, drought and seedling protection, urban flood control, aquaculture, temporary water transfer, cofferdam pumping, industrial drainage, municipal drainage, etc. The mobile pumping station is a unit that combines the pump and the motor closely together for submersible operation. my country’s submersible pumps have undergone four stages of development. By the 1990s, the types, varieties, output and quality of the pumps were relatively stable. Because the submersible electric pump has the advantages of simple structure, convenient use, etc., and the continuous improvement of the power grid, it has been widely used. Submersible electric pumps only need outlet pipes, so welded steel pipes, rubber hoses and rubber hoses (similar to fire hoses) have certain applications.

    The mobile pump station plays an important role in drought resistance and seedling protection. In the event of a drought, in remote areas without fixed pumping stations or when the flow of fixed pumping stations is insufficient, the unit fails or the water level is too low and fixed pumping stations cannot operate, the characteristics of mobile pumps’ strong mobility can be fully utilized to mobilize a large number of pumps in a short time Station to solve the drought. Drought resistance and seedling preservation generally take a long time to run, but the time requirement for reaching the job site is not high.
