Q:QDX is a submersible pump. What does "X" mean?
It should be small.There is no "downdraft" term;Do not say submersible pumps do not suck, what kind of pump is not on suction, or left and right suction
Q:Pump house should be equipped with those equipment and valves
1. The inlet and outlet of the pump shall be equipped with a control valve, and the outlet shall be equipped with a check valve;2, lower than the pump suction the water tank, water pump entrance to bottom valve, and piping and valves equipped with irrigation. Or equipped with other water pump irrigation facilities.3, more than one pump system should have the total valve and contact valve.4, the corresponding control equipment.
Q:Is there a water pump with its own flow regulating function?
Pump with adjustable flow depends on your useThe ordinary displacement pump, which has a small flow rate, can set the flow rate per second into the system and is widely used in the laboratory.Large flow regulating flow pump is mainly variable frequency pump, through the electrical signal feedback regulation, change the pump water storage flow.The main thing is to see your flow, and then determine what you want to pump!
Q:Water pump eliminates air
By rotating the water pump is thrown from the impeller center, resulting in pressure, the back of the water sucking over, this is the pump working principle, if air, air will not be left out without impeller, the flow rule, no pressure, so we can not draw water!
Q:Pump adapter joint net outside tube, what is the principle?
At once the room after the fire, the internal fire pool once water shortage, the water tank can be within the fire truck hit the water chamber through the pump adapter connected to the fire extinguishing effect.
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 is the definition of the pump in the capacity of the pump?
Work pump, spare pump, repair pump three are interchangeable use, the work pump need to overhaul, repair pump work, work pump is maintenance pump. The capacity of the water pump is not less than 25% of the work pump. If the work pump, spare pump, repair pump model is the same, the work pump 4 units, repair pump at least 1 units, 5 pumps, repair pumps need 2 units
Q:The flow of the pump will be reduced, the speed will change, the power of the motor will change?
Water pump flow rate, speed will not change, the power of the motor will change in general.Different types of pumps have different flow power curves. Only the most common centrifugal pump is used as an example to illustrate the relationship between the flow rate and other pump parameters. The typical centrifugal pump flow power curve is shown in the P-qv curve (red line) shown below.Turn left and turn right |According to the flow power curve, it can be seen that with the increase of the flow rate, the power increases linearly, and the power decreases linearly with the decrease of flow rate.In fact, the pump shaft power P= P gQH/ (1000 K), including H: head, unit m, Q: flow unit m3/s, ETA: for the efficiency of the pump, general 0.7-0.85, P: shaft power, unit kW, K: matching coefficient, small power is 1.25, P: work is like a water medium density.Therefore, for a specified pump, the power is proportional to the flow theoretically. In fact, as the flow rate changes, the efficiency of the pump changes, so it can only be close to the positive proportion.Running water pump speed generally depends only on the pump, power (motor, diesel, etc.) speed, the flow of water generally can not affect its speed. But in the design of pumps, the flow is related to the speed, and other design parameters remain unchanged, the pump speed is high, the pump flow.
Q:Does the pump accessories have a shelf life?
Yes, 3-6 months for wearing parts, 12 months for general accessories, 10 years for shell type. Specific depends on whether the materials and user use conditions are bad to decide.
Q:(flood control emergency plan) what type of water pump should be used for flood control? How to choose
Select the QW submersible pump, which is potential water, (flow, lift, bore, power)Flow, how many tons of water pump an hour to play, you choose how much?Lift, water pump from the destination is a few meters, how many meters?,Caliber, this pump potential water, without flange connection, only flow, head can reach.Power, look at the flow and lift is how much, and then choose the right motor (this is regular)The voltage is usually 380V.You can move, it is best to fix a seat, weight, this pump is basically a person can not move, and small can take.Brand, regular manufacturers can.Model, (caliber, flow, lift, power, voltage) tell the manufacturer.
