The mobile pump truck is developed according to the characteristics of suddenness, urgency, operational diversity and social influence, which are formed according to the long-term storage, lack of maintenance, poor working environment and special operation requirements of the disaster relief equipment, compared with the traditional pump. The new generation of mobile pump trucks combines a number of modern concepts and is more powerful.
Characteristic analysis
1. The mechanical energy storage starter replaces the conventional starting mode of starting the engine by the starter battery powered by the starting battery. Since the mechanical energy storage starter directly applies mechanical energy to start the engine, it is possible to eliminate the occurrence of failure of the starting battery due to long storage time and low temperature, so as to ensure that the engine starts smoothly in a maintenance-free state.
2. Replace the fan-type engine of the conventional application with an air-cooled engine as a power machine. Because the air-cooled engine relies entirely on air for cooling, it not only eliminates the need to fill the tank in a tight state, adds special coolant operation and resource supply, but also eliminates the maintenance and failure of the fan tank to ensure that the engine is maintenance-free. Reliable operation under emergency conditions.
3. Replace the conventionally applied electric excitation generator with a permanent magnet generator for power generation. Since the permanent magnet generator does not have vulnerable parts and circuits such as field windings, rotary rectifiers, pressure sensitive components, excitation generators, voltage regulators, etc., it has high efficiency, simple structure, reliable operation, small size, light weight and maintenance-free. And other characteristics. At the same time, even if the generator is soaked in water, it is only necessary to directly short-circuit the stator, and the operation can be resumed after running at a low speed for 4 hours, so that there is a strong regenerative property.
4. Replace the centrifugal pump of conventional application with the piston rotor pump for pumping operation. Because the piston and rotor pump has the characteristics of air, liquid and solid mixing and conveying at the same time, it can be quickly input without watering and watering. At the same time, it can not only transport clean water, but also transport water and sewage with impurities without fear of blockage; Chenggao (0~8m), wide lift (0~80m), wide flow (0-1500m3/h), automatic adjustment of head and flow characteristics, so it can automatically adapt to the working environment and operation requirements within the rated power range. Achieve long-distance water absorption (horizontal water absorption distance up to 80 meters), long-distance water delivery (horizontal distance up to 400 meters), large-flow water delivery (horizontal transportation can reach 1500 cubic meters per hour, which is equivalent to the water volume of a standard swimming pool At the same time, the same equipment can be used for different operations of drainage, water supply and fire protection.
5. Replace the conventionally used chemical battery with a super capacitor battery as the control system and 24V lighting to provide power. Because the supercapacitor has the characteristics of storage resistance and low temperature resistance, it can ensure the power supply is maintained in maintenance-free and low temperature conditions.
6. Using a diesel engine to coaxially drag a generator and a water pump, so that a disaster relief equipment can carry out electric energy and pumping work simultaneously or separately. In response to the high application rate of power supply and pumping in the rescue and disaster relief, our company has applied the innovative method to develop the world's first dual-function integrated equipment for power generation and pumping for disaster relief, effectively solving the disaster relief activities. Frequently encountered difficulties in entry, narrow working surfaces, and multiple tasks in parallel.
