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 characteristics of the piston pump?

Piston pump is an important device of hydraulic system. It depends on the plunger in the cylinder in reciprocating movement, so that the volume of the sealing chamber volume changes to achieve oil absorption and oil pressure. Plunger pump with a rated pressure, compact structure, high efficiency and flow and easy adjustment, is widely used in high pressure and large flow and flow needs to adjust the occasion, such as hydraulic machine, engineering machinery and ships.

Q:What flowmeter is installed after the pneumatic diaphragm pump?

The pressure decreases, the diaphragm moves slowly, and the flow decreases.This is not particularly accurate, because the diaphragm is not a metering pump, but the approximate flow can still be controlled.

Q:Does the reservoir water heater press the booster pump (high marks)?

60 liters of water storage should be able to drive two bathrooms at the same time bath! Water storage water heater generally does not need booster pump, as long as there is a little pressure, the water heater is filled with water, as long as the tap water can do. You can turn off the hot water valve and see only the amount of water in the cold water. If hot water is much smaller than cold water, it is the reason for the heater. Can you check the water mixer is normal, the one-way valve is installed in reverse.

Q:What does "efficiency" mean in a water pump catalog?

The efficiency of the water pump nameplate refers to the maximum efficiency that the pump can reach at the rated speed

Q:5 floor water pressure is too low, what kind of water pump is better?

The location of the pump is too far away from the pumping pool, the suction of the pump is not enough, cavitation phenomenon, pumping water, this water pump manufacturers, the pump will be placed in a reasonable position

Q:How high can the pneumatic diaphragm pump be?

If the pump material made of polypropylene (PP) material, corrosion resistance, good chemical resistance using PP material produced by pneumatic diaphragm pump can resist medium low cost, good generality, polypropylene material mainly is especially suitable for general acid-base liquid, using poly propylene made of plastic gas diaphragm pump can only withstand the highest temperature to 65 degrees, more than this number of polypropylene plastic deformation.

Q:What is a water pump coupling device?

Advantages of water pump coupling device:1. automatic coupling device, easy installation and maintenance. In the absence of automatic coupling device, fixed installation, such as water pump failure, maintenance personnel need to unscrew screws, lifting pumps for maintenance, or with other small pumps pumping water perfect maintenance,If the water is dirty, it is difficult for people to get down, when the inspection and repair encountered great difficulties. But it is equipped with GAK submersible sewage pumpAfter the automatic coupling device needs lifting, the person can directly lift the water pump without the need to screw the screw into the waterAfter graduation, down the guide rail, you can realize the sealing of water pump and pipeline, so as to make the pump run normally. Small sewage pumps are freeInstallation, large sewage pumps are generally equipped with automatic coupling device, automatic installation, installation and maintenance is very convenient.

Q:What are the important parameters of the pump?

Pump parametersFlow rate QFlow is the amount of liquid (volume or mass) that is pumped out in unit timeVolume flow is expressed in Q units: m3/s, m3/h, l/s, etc.

Q:What does "dual purpose" of water pump mean? Please expert advice

2, the pump must pay attention to maintenance after use, for example, when the pump is used up, the water pump should be put clean, it is best to remove the water pipe, and then rinse with water.5, the water pump on the tape should be removed, and then rinse with water after drying in the light place, do not put the tape in the dark damp place. Water pump tape must not be stained with oil, not to tape coated with some sticky things.6, to carefully check whether there are cracks in the impeller, the impeller fixed to the bearing on whether there is loose, cracks and loose if the phenomenon to be timely maintenance, if the water pump impeller should also be above the earth clean.
