diesel engine fire fighting

Diesel engine fire pump has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long life, convenient installation and maintenance, etc. This diesel engine pump set can transport clean water or other liquids whose physical and chemical properties are similar to water. It can also be used to transport hot water, oil, corrosive or abrasive media by changing the material of the pump’s flow parts, sealing form and adding a cooling system. Specifically, it can have the following uses.

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 trailer-type mobile pump truck is also called the traction-type mobile pump truck, which is mainly used for mobile drainage equipment by external force dragging or traction. The trailer-type mobile pump truck is mainly composed of a drawbar, a car base, and a diesel engine water pump unit. The unique design of the pump body and impeller flow path of the diesel engine water pump makes the pump unit of the trailer-type mobile pump truck no need to install like a clean water pump. Water diversion and bottom valve can also absorb and discharge water with large particles and long fiber impurities.

Trailer-type mobile pump truck is also called mobile self-priming drainage pump station, and can also be referred to as mobile pump truck, pump truck, mobile pump unit, mobile pump station, etc. Trailer-type mobile pump truck is a kind of mobile pump truck developed by our company. A self-priming pump driven by a diesel engine is a pumping device with strong self-priming capability.

The trailer-type mobile pump truck adopts the axial return and external mixing type, and through the unique design of the pump body and impeller flow channel, it can not only need to install a bottom valve and irrigation water like a general self-priming clean water pump, but also can suck and discharge large solids And long-fiber impurity liquid, widely used in flood control and drought relief, municipal sewage discharge, emergency drainage and other fields.

The mobile pump truck mainly relies on the rotation of the impeller to create a vacuum zone, and the inhaled liquid relies on the centrifugal force developed by the impeller to generate a large amount of pressure and a very fast speed. Stainless steel and other materials are available for selection. Private customization is also possible, and customers can design reasonably if they need it. The mobile pump truck inputs a part of the energy into the diversion shell and steps into the impeller of the next level. The pressure generated increases in proportion to the number of pumps, and then passes through the water pipe pump base to reach the pipeline program on the construction ground. Based on scientific design thinking and technical improvement in long-term practical operation, the mobile pump truck will enhance its image as a smart and practical new pump truck in terms of the entire water displacement treatment.

The design of the mobile pump truck can highlight the integration of cutting-edge science and the combined control of various systems, reducing the weight of the entire mobile pump truck, eliminating the heavy and rough image of the previous water pump, and reducing the input of operators. , It is also convenient for multiple transportation, long-distance transmission is no longer a problem and ensures timeliness, but its own emission performance will increase without decreasing, and the displacement that can be handled has increased, while the pump truck itself has reduced the size of the traditional pump truck. Ten times as much in weight. The construction personnel can easily make up for the more tragic losses caused by the mobile pump truck before the floods rage.

The diesel engine fire pump unit is directly driven by the diesel engine fire pump, and it is a mechatronic equipment that can start and complete the water supply in a short time. The diesel engine pump set is driven by a diesel engine without external power supply. Diesel pumps are suitable for fire water supply occasions such as agricultural irrigation, emergency rescue, smelting, hangars, petrochemical oil depots, power plants, liquefied gas stations, and textiles. Especially when there is no electricity and the grid is not satisfied, choosing a diesel engine-driven water pump is the safest choice.

As a fixed firefighting equipment, diesel engine fire pump has been widely used in firefighting and shunting, especially when there is no power supply or power supply (main power supply).

The main advantage of the hand-held diesel fire pump is the high lift, which can reach 90 meters. It is generally used for fire emergency fire prevention, forest emergency fire prevention, and factory fire protection. When the diesel engine fire pump is working, the auxiliary impeller is together with the pump main shaft Rotating, the liquid in the auxiliary impeller will also rotate together, and the rotating liquid will generate an outward centrifugal force. On the one hand, this centrifugal force resists the liquid flowing to the mechanical seal, reducing the pressure at the mechanical seal. On the other hand, it prevents the solid particles in the medium from entering the friction pair of the diesel engine fire pump seal, reduces the wear of the mechanical seal grinding block, and prolongs its life. The auxiliary impeller of the diesel engine fire pump can not only play a sealing role, but also reduce the axial force. In the diesel engine fire pump, the axial force is mainly caused by the pressure difference force of the liquid acting on the impeller and the gravity of the entire rotating part. The direction of action of these two forces is the same, and the resultant force is formed by the addition of the two forces.
