Diesel engine is an internal combustion engine with the lowest fuel consumption, the highest thermal efficiency, a wide range of power, and various speeds in thermal power machinery. It has also been widely used in the water pump valve industry. Diesel engine water pump generally refers to the diesel engine as the power, the pump unit is driven by the diesel engine through the elastic coupling. It has the advantages of advanced and reasonable structure, high efficiency, good cavitation performance, low vibration, low noise, stable operation, reliability and convenient assembly and disassembly. People usually name water pumps according to a few inches, such as 4-inch diesel engine water pump, 6-inch diesel engine water pump, 8-inch diesel engine water pump, so what do these sizes mean?
In fact, the 4-inch water pump means that the inlet and outlet diameter of the diesel engine pump is 4 inches (inner diameter 100mm), and the 6-inch water pump means that the inlet and outlet diameter of the diesel engine pump is 6 inches (inner diameter 150mm). The 8-inch water pump also means The inlet and outlet diameter of the water pump is 8 inches (inner diameter 200mm). Among the several models, the commonly used 6-inch diesel water pumps can reach 200m3/h. The head can be as large as 80 meters according to the demand. Usually, the most used A 6-inch diesel water pump with a flow rate of 200m3/h and a head of 22 meters. This parameter corresponds to a diesel engine power of 33KW and a speed of 1500r/min. The pump body can be made of HT250 (the pump body weight is 148kg) or aluminum alloy. (The weight of the pump body made of alloy aluminum should be reduced by about 90kg, and the actual weight is 55kg). The flow parts are all made of stainless steel. The big advantage of the 6-inch diesel water pump is that it has excellent non-clogging effect and has changed the previous self-priming The disadvantage of the low self-priming capacity of the pump is that it does not use any auxiliary system for drainage at a self-priming height of 8 meters. It only takes less than 1-2 minutes to fill the pump body with water once at a self-priming height of 8 meters. The water can be easily sucked into the pump body to drain away.
In addition, if the diesel engine adopts 1800r/min, the flow rate of the 6-inch diesel engine pump can reach 435m3/h, and the head is 29 meters.
Main features of 4 inch diesel engine water pump, 6 inch diesel engine water pump, 8 inch diesel engine water pump
1. 4-inch water pump, 6-inch water pump, and 8-inch water pump have good anti-clogging effect. As long as the impurities and fibers can be sucked into the pump body, they will be discharged, and the diameter of large particles can reach 100mm.
1. With super self-priming ability and without vacuum auxiliary system, the self-priming height is 8 meters and the total length of the pipeline is 15 meters. It only takes less than 2 minutes to discharge water.
2. The front of the pump body is equipped with a removable cleaning cover, which is convenient for users to clean up if solid particles exceeding 100mm are sucked into the pump body and blocked during use.
3. The impeller is made of stainless steel 304 to make its service life, wear resistance and collision effect more durable than cast iron impeller.
4. The same pump body can change the diameter of the pump inlet and outlet to realize the function of adjusting the flow and head. It can be equipped with 4-inch, 6-inch, and 8-inch quick-release joints to meet the needs of different working conditions. It can be multi-purpose and one machine can be realized. The pump body meets different parameter requirements. The flow rate is 100m3/h and the head is 28 meters when the pump is 4 inches, the flow rate is 150-200m3/h when the pump is 6 inches, and the head is 22 meters, and the flow rate is 250m3/h when the pump is 8 inches. -20 meters.
5. The inlet and outlet are equipped with quick ball joints, which is convenient for users to quickly install inlet and outlet pipes during on-site use.
6. 4-inch diesel engine water pump, 6-inch diesel engine water pump, and 8-inch diesel engine water pump can all use the same 4-wheel solid tire trailer, which is convenient for users to mount and move. The trailer steering adopts a new steering principle design. If the pump body is made of alloy aluminum, the whole machine It is lighter in weight and more convenient to use on site. It can be easily moved without multi-person dragging. In summary, the 4-inch mobile diesel water pump, 6-inch mobile diesel water pump, and 8-inch mobile diesel water pump are due to our optimized pump bodies. Design, the above several models can meet the demand with one pump body.
