Five reasons why the temperature of the diesel engine fire pump is too high

Diesel engine fire pumps can be divided into self-priming type, centrifugal type and double-suction type products. The self-priming type is mainly used for liquids with a relatively low level of suction, such as stagnant water in sewers and under bridges. Currently, diesel engines Self-priming pumps are widely used in urban flood control and emergency rescue. Centrifugal pumps are divided into two types: single-stage centrifugal pumps and multi-stage centrifugal pumps.

Diesel engine fire pumps can overheat for several reasons:
1: The diesel engine fire pump is overloaded. Therefore, in the operation of the fire pump, the high-speed and overload operation of the diesel engine must be avoided.
2: The oil radiator of the diesel engine fire pump is blocked by foreign matter, resulting in poor heat dissipation;
3: The position of the oil temperature adjustment switch of the diesel engine fire pump is incorrect. In summer, the oil will not dissipate heat through the radiator;
4: The cylinder of the diesel engine fire pump leaks, high-temperature gas enters the oil pan, and heats the oil in the oil pan.
5: The cooling fan speed of the air cooler of the diesel engine fire pump is too low, which reduces the cooling intensity and increases the body temperature of the diesel engine.

    More Mobile pump

    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 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.
