The application of diesel trash pump is the trend of the times

    During the operation of the diesel trash pump, the water flowing in the pump is affected by the friction with the surface of the runner and the pump impeller and the viscosity of the water body. The energy consumed by the pump is mainly used to resist the flow friction and eddy current resistance of the water surface.

    The energy consumed by water during the flow is used to overcome the friction between the internal friction and the interface between the water and the equipment. If the surface of the pump and impeller is smooth, the surface resistance is small, and the energy consumption is small. The polymer composite material is sprayed on the flow surface of the diesel water pump and the impeller to form a hydraulic smooth surface. The surface smoothness of the ultra-smooth surface coating is polished. 20 times behind stainless steel, this extremely smooth surface reduces the stratification of the fluid in the pump, which reduces the internal turbulence of the pump, reduces the volume loss and hydraulic loss in the diesel pump, and reduces the power consumption.

    The trailer mounted pump achieves the purpose of reducing the loss of water flow resistance, thereby improving the hydraulic efficiency of the diesel water pump, and at the same time improving the mechanical efficiency and volumetric efficiency to a certain extent, the compactness of the molecular structure of the coating, and the isolation of air, water and other medium and water pump impellers. Contact with the base metal to reduce electrochemical corrosion and rust. In addition, the polymer composite material is a high molecular polymer, which is chemically resistant, can improve the corrosion resistance of the pump, and can greatly enhance the erosion resistance and corrosion resistance of the diesel water pump.

    The diesel engine irrigation pump uses the frequency conversion speed regulation to realize the constant pressure water supply. Compared with the constant pressure water supply by adjusting the valve, the energy saving effect is very remarkable. The starting balance can be limited to the rated current, thus avoiding the impact on the power grid during starting. . Since the average speed of the diesel water pump is reduced, the service life of the pump and the valve can be extended, and the water hammer effect at the time of starting and stopping can be eliminated. Generally speaking, when one motor is controlled by one inverter, it is only necessary to match the capacity of the inverter with the actual motor capacity.

    When the diesel dewatering pump inverter controls two motors at the same time, in principle, the capacity of the inverter motor should be equal to the sum of the capacities of the two motors. However, if the water consumption at peak load is much different than the speed of the two diesel engine water pumps, consider reducing the capacity of the inverter appropriately, but be careful to leave enough capacity. When the diesel water pump is running at low speed, the operating current of the motor is small. However, when the user's water consumption changes frequently, the motor will be in a frequent rising and falling state, and the current of the rising and falling speed may slightly exceed the rated current of the motor, causing the engine driven water pump to overheat.
