<4>Working Principle

When the equipment is put into movement, the water from the tap-water pipe-net flows into the flow stabilizing can. When the water supply capacity of the pipe-net can meet with the demand of use, the pressure of it is kept with the normal water supply range, the negative-pressure preventing module controlled electric valve is opened and the pump moves to carry out the pressure-overlapped water supply; While the said capacity can not meet with the demand, the pipe-net pressure is lower than that for normal water supply, the said module automatically adjusts the opening of the electric valve till its being closed, at this time water supply by the flow stabilizing can is automatically switched in. The vacuum eliminator on the said can is opened therewith, preventing a negative pressure from being produced inside of the can.

Q:How do you do the yellow water from the suction pump?.
If your pump is iron, it must be impossible to avoid rust, and if you replace it with stainless steel, there will be no problem.There is also a way to add a filter or water purifier at the front of the pump to make it a little better.You can change the flow parts into stainless steel, but the price may not be cheap
Q:Variable flow variable frequency water pump how to adjust the flow?
Variable frequency pump is mainly depending on the frequency converter to adjust the speed of the pump motor, thereby regulating the flow and lift pump, the following Q1/Q2=n1/n2; H1/H2= (n1/n2) -, the frequency range of the frequency converter in 30HZ~50HZ
Q:Does the water pump and the circulating pump belong to the centrifugal pump?
As long as the flow and head to meet what pump can be, the general centrifugal pump applications are more.
Q:TDH what units are present in the pump parameters?
Answer: TDH stands for single pole double suction horizontal chemical process pump, suitable for conveying clean or containing micro solid particles of ultra low temperature or high temperature liquid medium, is also particularly suitable for conveying strong corrosive medium. All facilities for horizontal installation are available.Mainly used:Petroleum smelting plant, petroleum conveying equipment and pump used in petroleum deep processing devicePump for coal chemical processPumps for water and desalination systemsPumps for fuel coal fired power generation equipmentSewage treatment and environmental protection pumpStructure characteristics:Pump in the horizontal opening, suction and discharge pipeline is located in the lower half of the pump body. The disassembly and replacement of the wearing parts and the replacement of the rotor parts can be performed without disassembly of the pipe.Double suction impeller, high efficiency, good cavitation performance, axial force is basically balanced.Rigid axle shaft and bearing, double end support, small deflection, small vibration, low noise, oil lubrication of rolling bearings with oil ring, constant level oiler automatic control level, and can get automatic compensation, radial thrust ball bearings back-to-back bear residual axial force.The sealing ring of the shell is provided with a stop and a step, and is arranged on the pump body and the pump cover, so that the assembly and disassembly are convenient.
Q:The pump assembly and the pump are not a thing
Yes, all the auto parts are called assembly, and the pump is the same. It's called water pump assembly. Also, the pump half assembly is the water pump head.
Q:Why should we pump water into a pump when the country uses a pump to pump it?
Because it is not a self-priming pump, so add water, otherwise there is no pressure can not afford
Q:Electrical design into!!! Is the water pump lamp waterproof?
No specific requirements are available
Q:What's the water pump?
Cooling water pumpDetermination of water replenishing pump1) the hourly flow is 4%~5% and the total water quantity is.2) the lift is the replenishment point and the pressure is plus 30~50 kPa.3] water pump to overcome the pressure of the replenishment point and the pressure difference between the make-up water tank, during which the pipeline is not long, you can ignore its resistance4) open system replenishment, no replenishment pump
Q:Pump head is too high what's the impact?
After the determination of the pump type, such as the actual pump lift is too high, it will not only result in lower efficiency of the pump, and will seriously affect the actual flow of the pump to Q decline. On the contrary, if the pump head selected too high, but the actual operation of the lift is too low, is also affecting the pump efficiency and decrease caused by actual operation when the flow is too large, it is likely to increase the pump power beyond the rated current of the motor and the heating.
Q:37KW how many contactors does the pump need to start directly?
First of all, you have to see what voltage you use If 380V then current per KW is about 2A, if it is 660V per KW at about 1.1A, then it is the starting current is 3 to 7 times for the starting current, but for the moment, 380V voltage: 37*2=74A 100A on the line, 660V voltage: 37*1.1=40.7A 63A on the line.
