China Do Pump, Dredge Pump for sale, is going to show us the calculation of dredge pump engine selection, so what are the determination of dredge pump engine calculation, how to calculate the engine power of dredge pump according to dredge pump for sale working capacity, transfer distance, suction depth, solid material, solid density etc. Dredge pump for sale China Do Pump is a dredging pump solution provider, for how to select a dredge pump, dredge pump for sale, Dredge pump for sale, how to calculate the engine power of dredge pump, here comes to the answer.
how to calculate the engine power of dredge pump:
Dredge pump for sale are highly used for mining, dredging, reclamation, river, sea solid dredging and piping. in the design of dredge pump for sale, dredge pump engine is normally used in electric or diesel engine, and the commonly formula is:
v=(QpH3Hr/102η3η)η0
v - motor power, kW;
Qp - dredge pump flow, L / s;
Rn - density, kg / L;
H3——the head of the selected pump, the liquid column;
Η5——dredge pump efficiency,%;
η——Mechanical rotation efficiency, %;
Η0——power margin factor.
The engine power that is provided in the sample is based on clear water of the dredge pump. Therefore, the density of the slurry in different piping systems should be fully considered in the design of the dredge pump for sale. Under the dredging system, solid are divided into qualified medium system, dilute medium system, concentrated medium (replenishment medium) system, concentrate system, tailings system. Among them, the qualified medium density is 1.4-1.8kg/l; the dilute medium density is 1.25~1.35kg/I; the concentrated medium density is 1.8-2.0kg/L; the concentrate density is 1.2. ~1.3kg / L; tailings density of 1.1 ~ 1.2kg / I; slime water density of 1.05 ~ 1.15kg / L. Dredge pump for sale - how to calculate the engine power of dredge pump.
Three factors to select dredge pump engine:
(1) Select the engine according to the required maximum power of dredge pump, torque and number of revolutions. The rated power of the engine is slightly greater than the designed shaft power of the dredge pump. The starting torque of the motor is greater than the starting torque of the pump. The number of revolutions of the engine should be basically the same as the number of revolutions of the dredge pump, or in design of dredge pump on sale, the dredge pump can be driven by belt with the engine, in order to change the roating speed in different working speed.
(2) According to the power of the engine, the electic engine voltage and frequency need to be considered during dredge pump for sale. Dredge pump for sale - how to calculate the engine power of dredge pump
(3) Determine the degree of protection of the engine according to the working environment and conditions of dredge pump for sale. Under dry and dust-free conditions, engine with general protection grades can be used; where there is excessive dust, splashing of coal mud, moisture, dripping or water storage, engine with a higher degree of protection should be used.
Hereby, dredge pump for sale, China Do Pump shows the determination of dredge pump engine calulation and selection, as a dredging pump solution provider, China Do Pump - Dredge Pump For Sale would like to share more knowledge about how to calculate the engine power of dredge pump, therefore, contact us at info@dopumpgroup.com or call us at +8615031104888.
