Wear-resistant mining centrifugal pump flow head selection and piping layout

In the practical work, for a wear-resistant mining centrifugal pump, the head and flow rate are two important parameters, when wear mine centrifugal pump type is determined, the size of the consumed power is proportional to the actual flow pump. And water pump flow will decrease with the increase of the head, and the higher the head, the smaller the flow, and the smaller power consumption. Conversely, the lower the head, flow rate, the greater the consumption of power. In order to prevent the motor overload, general requirements water pump's actual water use head shall not be less than 60% of the labeling head. When high lift for low head drainage, motor easy to overload and fever, serious when can burning motor. station work procedures, requirements are fitted on the outlet pipe gate valve, in order to reduce the water pump motor load startup, should be closed gate, after waiting for motor starting 1 a 2 seconds, then gradually open the gate.

wear-resisting

selection mining centrifugal water pump head wear mine centrifugal pump head is not carry water height, clear that to choose the pump is particularly important. head is about 1 water height. 15 ~ 1. 20 times. Such as a water to water the vertical height of 20 meters, the head needed for about 23 ~ 24 meters. Choosing pumps should make water water pump nameplate on the head with the best head needed close to such a case, the pump efficiency is highest, use will be more economic. But not necessarily demands absolute equal, general deviation as long as no more than 20%, the water pump can be in the energy conservation work.

wear-resisting mining centrifugal water pump water pump flow and the choice of pipe layout

wear-resisting mining centrifugal pump flow, generally unfavorable choose too large, otherwise, would increase the cost of buying pumps. Should be specific analysis, according to the displacement considering various factors such as traffic, right to ensure that the needs of normal production. When decorate line, should pay attention to the following contents:

1) Choose the pipe diameter, pipe diameter is big, under the same flow rate, liquid flow velocity is small, small resistance loss, but the price is high, the pipe diameter is small, can lead to resistance losses increase sharply, increase the selected pump lift, installed with power increasing, the cost and operation cost are increased. Longer see in which of the following is the work of the pipeline, the flow rate and flow rate table.

       ( 2) Discharge pipe and the pipe joint should be considered are the biggest pressure.

       ( 3) Pipe layout should decorate straight pipe as far as possible, try to reduce the attachment and try to narrow the pipe length, pipe must turn, elbow bend radius should be 3 ~ 5 times the diameter of the pipe, as much as possible Angle is larger than 90 ℃.

       ( 4) The discharge side of the pump valve must be installed ( Ball valve or valve, etc. ) And check valve. Used to adjust the point of pump, valve check valve when the fluid flow reversal can prevent the pump inversion, and makes the pump to avoid water hammer blow. ( When the liquid flow back, will produce a great reverse pressure, make the pump damage) 。
