200 m head of high pressure large flow pump equipped with electric power parameters

360 m head of high pressure large flow pump with motor power is how old? What are the models? Specific parameters?

high pressure large flow pump in the 360 m head there are a lot of, equipped with a motor power is 200 kw, 280 kw, 800 kw, 900 kw, 1600 kw, specific or want to choose according to the parameters such as flow conditions. Such as double suction split case pumps dk360 models of flow in the 1100 m after 250 / h, 305. After 5 m/h, power is 1600 kw, and similar Yu Qingshui other liquid is suitable for conveying water, such as running water.

if it is to transport corrosive liquids such as salt water, acid, lye, stainless steel multistage pump DP600 - can be used 60 x 6 self-balancing multistage centrifugal pump, the flow parameters in the 600 m after/h, 166. After 67 m/h, matching motor power is 800 kw, the efficiency is as high as 82%, suitable for chemical industry contains corrosive liquid.

water pump motor choice to choose according to shaft power; The motor power is greater than the shaft power a grade; Such as: shaft power of 15 kw, choose motor should be as follows: 18. 5 kw as to use a few pole motor, according to the actual working condition requirements. Generally used in the 2 pole motor head high, flow is case ( Calculation is more complicated) 。 Traffic head small occasions can choose 4 pole motor. Large flow, low head back to choose 4 or 6 pole motor, when choosing six pole motor, power can be according to the shaft power decrease a level.

high pressure large flow pump motor power calculation methods: p = pgQH/( n1n2)

type: p - — The motor power, W; P = the density of water, p = 1000 kg/m ^ 3; g— — Acceleration of gravity, g = 9. 8米/秒^ 2; Q— — Traffic, m ^ 3 / s; H— — Head, m; n1— — efficiency; n2— — The motor efficiency.

water pump motor ( 泵马达) The classification of the structure should be divided into horizontal and vertical motor. Due to the working characteristic of pump to start torque is relatively small, relatively small start frequency, continuous operation and other characteristics of a relatively long time, so most of squirrel-cage rotor asynchronous motor water pump motor and synchronous motor.

At a time when technology is essential for submersible pump, ensuring that it works in a symbiotic way with your human employees is key.
