The difference between diesel trash pump and diesel clean water pump

The difference between diesel trash pump and diesel clean water pump

Diesel trash pumps also have their own structural characteristics, and their lifts are not high. Because there are more debris in the diesel trash pump, the clearance of the impeller is larger than that of the diesel clean water pump. Therefore, the diesel trash pump is prone to failure. Similar to a general centrifugal pump, because it needs to pump sewage/waste water, the impeller wears quickly. Because diesel trash pump belongs to the scope of centrifugal pump, the structure and principle are the same as general centrifugal pump. The ordinary diesel clean water pump is designed to obtain the highest efficiency, that is to say, the performance structure parameters of the diesel clean water pump are combined to obtain the highest efficiency.
For pumps with special requirements such as diesel trash pumps, its efficiency cannot exceed the efficiency of diesel clean water pumps in the same period. The main reason why the efficiency of diesel trash pumps is lower than that of clean water pumps is that their flow passages are widened. The value of the efficiency drop is mainly related to the degree of widening.
The widening of the flow passage of the diesel trash pump is to prevent the impeller of the diesel trash pump from being blocked. It is simpler than the clean water pump and has no guard ring, so that it will not block impurities. There is also a sawtooth blade under the impeller, which can be adjusted up and down to take out some thread in the impurities or smash the cloth. Diesel clean water pump is used to transport clean water and other liquids with physical and chemical properties similar to clean water. It is suitable for industrial and urban water supply and drainage, high-rise building pressurized water delivery, garden sprinkler irrigation, fire pressurization, long-distance transportation, HVAC refrigeration cycle, Circulating pressurization of cold and warm water for farmland irrigation, bathroom, etc. and supporting equipment.
The diesel clean water pump connects the engine and the water pump as a whole, and the fulcrum bearing of the motor rotor in the engine is the water pump bearing, and the water pump impeller rotates through the rigid power transmission to work the pressure reducing valve. There is only a gap of 0.10-0.22 mm between the impeller of the pump and the vortex shell, and the sundries and sand particles can easily jam the impeller, making the motor rotor unable to rotate and malfunction. From the analysis of repairing water pump failure, the rate of damage to the motor due to impeller jamming accounts for more than 80%. If you find that the motor does not rotate when the power switch is turned off, you should turn off the power in time. The inductance generates a rotating magnetic field when the motor is working, and the motor will not be damaged in a short time. You can use a screwdriver to remove the back cover of the motor, and turn the fan blades left and right by hand until the back cover is flexibly installed before powering on.
