DL Vertical Multistage Centrifugal Pump

 

 

Application:

 

Widely used in urban water supply and pressure boosting, industrial cirsulating system and processing system, environmental protection water treatment and infiltration analysis system, liquid conveying, circulation and boosting of hot and cold clean water, soft water.

  

Stainless Steel type is also used for water with tiny content of alkali, mineral, distilled water, water for swimming pool and solution with chloride, but the allowed temperature of the liquid should be reduced.

 

 

Advantages:

1. Water-power model design, high efficiency and save energy.

2. There is vane wheel inside, the pump shell and main fittings takes with stainless steel punch, flow-road is very smooth, axle sleeve is hard metal tool, so that will be super-powerful long lasting using time, to prevent producing second pollution and its axle cover seals with wear-resisting machine, unreveal.

 

 

 

The range of parameter:

Capacity: 2 to 76 m3/h

Head: 15 up to 195 m

Efficiency: 72% up to 92.5%

Rotation Speed: 2900 r/min

Power: 0.37 up to 30 kw.

Q:1.5 kW three-phase pump with 600 meters line, should match what big line?
Do you want to see the line loss how much pressure drop, if you want to ensure the working voltage of certain you pump, 600m pressure drop should be two-way, namely power press 1200m, press 380V, 1.5KW working current is calculated according to 3A R=, according to the resistivity * length / cross-sectional area of =0.0175*1200/S=21/S, and the loss of pressure drop =R*I=21*3/S=63/S, S take 3, loss of pressure drop is about 20V, the comprehensive economic cost, take 3 more appropriate, if you are willing to take 5, 6 are never mind, the thicker the loss is smaller.
Q:Water pump 50HZ impeller and 60HZ what is different, why not the same?
Water pump 50HZ impeller and 60HZ impeller, its outer diameter is not the same, 60HZ impeller slightly smaller. Because the speed of the impeller of 60HZ is faster, the impeller is a little smaller.Flow rate and speed, impeller diameter into a relationship: Q1/Q2 = n1/n2=D1/D2;Head and speed into two relations: H1/H2 = (n1/n2) 2Motor shaft power and speed into three relations: P1/P2 = (n1/n2) 3From the above deduction, we can know that the motor speed formula is n=60f/p, in which n is motor synchronous speed, and F is supply frequency. P is the pole number of the motor. It is known that the power supply frequency of the motor is proportional to the speed of the f. Therefore, to obtain the same head or flow, high speed, to use a smaller impeller.
Q:In the design specifications, for example, the water pump requirement is two. What does that mean? Can 3 pumps be opened at once?
May not。Design is in accordance with the "two prepared" design, opened two units, has been able to meet the water supply requirements. And the electrical control parts are in accordance with the opening of two units, has been unable to meet the opening of 3 power distribution needs. The standby pump is only replaced when the running pump is out of order or needs downtime to maintain the water supply.
Q:Why can't vertical water pump use spring shock absorber?
Vertical pump power is small, the weight is limited, the pipeline vibration is limited, the general rubber shock absorber will be enough. It's no use. I'm sure you can't use the spring shock absorber.General construction, 7,5KW below is rubber shock absorber, above is spring shock absorber
Q:Is the pump lift horizontal or vertical?
A vertical, vertical lift is one meter (see environment), usually 5~10 times the horizontal distance
Q:What will the water pump reversal situation?
Reversal will also water out, but the amount of water is small, belong to "pressure water" effect, as if a basin of water, we do not shoot outward and down, the water will be out of the basin.
Q:What is the reason that the centrifugal pump outlet pressure decreases and the operating current increases?
Export pressure reduction generally 2 reasons: 1, blade wear, 2. mechanical seal leakageThe increase of electric current should be caused by severe wear of the friction pairs of mechanical seals, resulting in increased resistanceIt is suggested that mechanical seals and blades be changed.
Q:The water burst how to repair?
This is used by welding and making AB calls
Q:How many pumps does a 50 meter water head use?
Considering the pipe resistance and the water head, it is recommended to use the pump at 65 meters or so!
Q:What is the relationship between pump power, lift and flow?
N= QH/1000 gamma ETA gamma, severe liquid, cattle - ETA / m3; efficiency; N- kW; H- head, power meters;Q- volume flow per cubic meter / sec.
