Q:Double floor sewage pump circuit diagram of a small problem

Question 4 when you need backup, you need to switch the SA switch, but where you want it. For example, when the 1# pump is running and does not reach the high water level, the 2# pump will not operate. If SA is placed in the left position, 21 and 22 are connected, and the KT is electrically delayed, and the KAB action causes the 2# pump to function. After the KAB operation, the KT will be disconnected, restored to the ready state, and also convenient for KT to restart the power on time, and also avoid the time relay to work on a long-term basis.

Q:What are the functions of a disposable infusion pump?

This is a very professional question, ha!I only know disposable infusion pumpsAttached: intelligent medical infusion pump and its application

Q:There are second cutting, third cutting, why three times?

I used to do this job before. After the impeller is cut, the flow and lift will decrease. Sometimes, the same pump will be cut according to the needs of the impeller, so as to meet the actual needs, at this time, with the power of the motor will also be reduced

Q:The working principle of magnetic pump

Working principle of magnetic pumpN of the magnet (n is even) arranged according to the laws in the magnetic clutch assembly inside and outside the magnetic rotor, the magnet part consisting of magnetic coupling system. When the inside and outside the two poles in different relative displacements, two poles between the angle phi = 0, the lowest energy magnetic system; when rotates to the relative displacement is two poles, pole angle between phi = 2 pi /n, the magnetic system of magnetic energy. Remove the external force, due to the magnetic system of magnetic poles repel each other, magnetic magnet will return to the lowest energy state. So magnets in motion, driven by the magnetic rotor.

Q:How much water does the water ring vacuum pump run for an hour? If there is no steam separator, does the water vaporize?

Water ring vacuum pump is divided into many types, different sizes, different types, so water is different. As for how much water the no fixed amount, but to ensure that the water temperature is in 25 degrees, not more than 35 degrees can be.

Q:Brief description of centrifugal pump on / off operation

Two, centrifugal pump start(1) the pump entrance valve fully open, start motor, outlet valve fully closed, fully check operation of pump.(2) when the pump outlet pressure is higher than the operation pressure, the outlet valve is gradually opened to control the flow and pressure of the pump.(3) check whether the motor current is within the rated value, such as the pump in the rated flow operation, and the motor overload should stop the pump inspection.

Q:How to select metering pump head?

The main index affecting the selection of the pump head is the composition of the medium to be transported and added, as well as the pressure and the temperature of the external environment

Q:How many millimeters is the diameter of the water outlet of the four inch pump?

Here is a 4 inch inch, not rural, 1 inches =25.4 mm, 4 inches is approximately 100mm, with DN100 pipeline.

Q:What are the problems that should be paid attention to when using vacuum pumps?

What are the problems that should be paid attention to when using vacuum pumps?

Q:Household automatic booster pump, how much pressure to work automatically, the water pressure and how many kilograms?

With the pressure does not matter, because the pressure is small, it is necessary to boost the pump, the water pressure with the pipe flow and the size of the booster pump related
