6. Structure explanation of submersble water pump

1.Submersible electric pump is composed of five parts: water pump,submersible motor,water line,waterproof cable and control switch. Water pump belongs to single suction multistage vertical centrifugal pump.

2.Submersible motor adopts water-filled wet structure,internal chamber was filled with water for cooling the motor and lubricating the bearing.In the operation,due to the changes of temperature,the pressure of the filled water in the internal chamber also changes,it can be automatically regulated by pressure-regulating unit in the lower part of motor.

3.For preventing the sand getting into the motor,the sand-preventing unit including sand slinger and skeleton oil-sealed was installed in the upper part of motor,the whole motor was sealed tightly.

4.There are water injection hole and exhaust hole in the upper part of the motor and discharge hole in the lower part.

5.There are thrust bearing and thrust collar,mainly for sustaining remnant axial force of pump and the empty weight of motor's rotor.

6.The winding of motor stator adopts water-proof electromagnetic wire with good insulating and water-proof functions and rotor adopts squirrel-cage structure.

7.When used in the environment where there are large grittiness or corrosive water,it should adopt the submersible pump made from casting stainless steel or copper alloy.

Q:1 water pump frequency converter constant pressure water supply wiring diagram
This is a Fuji inverter, water pressure sensor, if it is remote pressure gauge, connect 11, 12, 13 ends, if the pressure transmitter 11 and C1 end
Q:What are the new regulations in the design of main and auxiliary water bin and water pump room in coal mine?
The main water bin must have a main bin and an auxiliary warehouse. When a sump is cleaned, another water tank can be used normally.When the normal water inflow is below 1000m3/h, the effective capacity of the main water tank should be able to accommodate the normal discharge of 8h.The effective capacity of the main water bin can be calculated by pressing type in the mine where the normal water inflow is greater than 1000m3/h:V = 2 (Q+3000)Effective capacity of V-- main water bin in type m3;Q-- mine hourly normal water inflow, m3.However, the total effective capacity of the main water storage tanks shall not be less than the normal water inflow of 4h.The effective capacity of the water tank in the mining area shall be able to accommodate the normal water inflow in the 4H mining area.There is a big difference between the maximum water inflow and the normal water inflow in the mine. The drainage capacity and the water storage capacity should be specially designed.The water inlet chamber should be set up. A sedimentation tank shall be provided for the filling of water sand, hydraulic coal mining and other gushing water with a large amount of impurities. The water storage capacity of short positions must often remain above 50% of total capacity.
Q:What is the current of the pump when it is started?
When the motor starts, the rotor changes from a prohibited state to a rotating state, requiring a great torque, and the current must increase. When the pump starts, because there is water, it is started with load, and the current will be greater.
Q:Water pump "rated lift: 6m" what do you mean?
Lift refers to the weight of fluid per unit weight after the pump, the pump is an important working parameter, also known as pressure head. Simply stated: rated lift 6M refers to the rated operating conditions of the pump, the increase of energy 6M water column height. Here's an example to help you understand:Example 2-1 the head of a centrifugal pump is now measured. The refrigerant is 20 DEG C water, the measured flow rate is 60m^3/h, vacuum pump inlet meter 0.02Mpa, outlet pressure gauge readings for the 0.47Mpa (g), the two known table between the vertical distance is 0.45M if the suction pipe of same diameter and pipe pressure pump, calculate the pump head.Solution:Check the water density at 20 centigrade 1.0*10e3kg/m3,H=0.45m (1Mpa approximately equal to 100 m water column)P exports =0.47Mpa (0.47*100 m water column, =47 m water column)P imports =-0.02Mpa (0.02*100 m water column, =2 m water column)P is the density of the liquidH=h+ (P -p / P g=0.45+ export import) (0.47*10e6- (-0.02*10e6)) / (10e3*9.887) =50.5m (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:50 meters deep well with what water pump: home?
What types of household water pump, self-priming pump, centrifugal pump, submersible pump, according to the size and utility of water pump, self suction pump is the advantage of direct water, normal household to 1500 watts can, but must keep the water clean, water there can be no silt or small sand. Centrifugal pump need drinking water, that is not self suction;But the advantage is a large amount of water. When used, the power will be reduced, because the use of centrifugal switch is automatically disconnected, energy savings can be used, the general household on these two, as for submersible pumps, home generally less than.
Q:Water pump mutual switching device
The main purpose of the control is to make sure that the pump outlet has a nominal pressure.Control requirement: 1. Start single pump manually.2, two pumps should alternate.3, the pump exports to achieve certain pressure, the normal operation of the motor, and the pressure is too low, the operation is meaningless.Device: AC contactor, intermediate relay, etc..Principle: 1, detect a pump fault (usually take the motor main contactor, auxiliary contact), interlock another pump to start.2, pump outlet pressure detection device detects low pressure, can start another pump at the same time, to ensure the normal export pressure!
Q:Relationship between pump voltage and lift?
In the case of power, W=F*S. That is, the work done per unit time pump = the gravity of the water flow * the displacement of the waterIt can be seen that:1, the power is certain, the head and the flow is inversely proportional.2, the greater the power, the greater the product of the head and flow.Therefore, when the flow is minimum, the pump head is the maximum; when the head is the minimum, the flow is the maximum.
Q:What is the difference between a fire pump and a living water pump?
1, fire pump is actually divided into many kinds, such as car, fire hydrant system, spray system, etc., life pump is also, the distinction between them is sometimes difficult to tell the exact. Simply put, the fire pump in its design must meet the corresponding fire requirements, such as pressure, speed, work adaptability, etc., specific requirements can be found in "national standard GB 6245-2006, fire pump Fire, pumps""2, the same function of fire water pump, its price is relatively stable. I personally feel that we must find more manufacturers to understand the reasons for the price difference, and then make a choice.
Q:Pump power ratio design is small, the problem is big?
Lift and flow to meet the requirements of power, in fact little difference, different manufacturers and brands in the same common effect of different power phenomenon, design principle is on the one hand, the hysteresis loss mechanical loss processing technology is one of the reasons of the differences. Power, after all, does not increase, and does not have a major impact on other lines.
