What is the maximum suction range of the pump?

Question 1: What is the maximum suction length of the suction pump? 6.5 meters is calculated according to the standard atmospheric pressure. In fact, atmospheric pressure and intake pipe loss should be considered, which are generally less than this figure after installation.

Question 2: Why can the suction range of water pump be higher than 10 meter? Yes, the atmospheric pressure is only 10 meter, which means atmospheric pressure 10 meter. Generally, the jet pump is higher than the suction range of 10M. It depends on two pipes and extends underwater. One suction pipe and the other are connected to the water inlet side of the suction nozzle. When the water pump starts. These two pipes form an internal circulation. The water flow forms jet negative pressure at the suction nozzle, which continuously absorbs water.

Question 3: How many meters can the self-priming pump reach? Small 10-20m, large 100m or more.

Question 4: What is the maximum suction range of the self-priming pump? According to our usage here, the vortex self-priming pump 10m absorbs water normally (the groundwater layer 18- 10m can't absorb water), while the spiral self-priming pump and the high-pressure jet self-priming pump absorb water normally at 20m (the water output of the groundwater layer is less at 25m).

Question 5: What is the maximum suction range of centrifugal pump? 1. Theoretically, the maximum suction range of centrifugal pump is local atmospheric pressure, so the calculated maximum suction range is 10 m water column.

2. In fact, the maximum suction range of the pump is about 8m water column.

Question 6: What is the maximum suction range of the suction pump? Theoretically, the maximum suction range is one atmosphere, ten meters of water column, which is actually not that big, and it can be achieved in engineering about six or seven meters.

Question 7: What is the maximum suction range of the pump? It is also called "maximum self-priming height" (it can also be understood as "self-priming degree"). That is, the maximum height at which the micropump can automatically absorb water without drawing water (the vertical distance between the suction port of the pump and the pumped liquid level).

Generally, when the water source is lower than or equal to the placement position of the pump, the pump needs to have self-priming ability. For example, outdoor travel requires pumping water from the river, and it is best to use a micro pump with self-priming ability (it is impossible for people to add some water to the inlet pipe before running into the river). Or the pumped liquid is corrosive and it is inconvenient to add water.

For example, there is a kind of water pump called BSP series, which is small in size, but the nominal water absorption range can reach 4 meters, and it can really reach 4 meters without water, which is relatively high among micro pumps.

Not all micropumps have self-priming ability ("suction").

Some centrifugal pumps have no self-priming ability, so it is necessary to add water for the first time. Although some micropumps also have self-priming ability, when the inlet pipe is full of air, there is a gap between the target "suction range" and the vertical height of the pumped water, and it may even be less than half. Therefore, the suction range is an important parameter when selecting the pump.

The lift of the lifting pump refers to the height at which the pump can lift water, usually expressed in H, and the unit is m. The lift of the centrifugal pump is based on the center line of the impeller and consists of two parts. The vertical height from the center line of the pump impeller to the water surface of the water source, that is, the height at which the pump can suck up the water, is called the suction lift, or suction stroke for short; The vertical height from the center line of the pump impeller to the water surface of the outlet pool, that is, the height at which the pump can raise the water pressure, is called the water pressure lift, which is referred to as the pressure lift. That is, pump head = suction head+water pressure head. It should be pointed out that the lift marked on the nameplate refers to the lift that can be generated by the pump itself, excluding the loss of lift caused by the frictional resistance of pipeline water flow. When choosing a water pump, you should not ignore the matters needing attention. Otherwise, there will be no water to pump.

Question 8: How many meters the suction range of centrifugal pump can reach is related to the cavitation allowance of the pump, the pressure loss of the suction device and the atmospheric pressure. The maximum is about 7 meters, and the minimum is negative, that is, the pump must be below the liquid level or have pressurized water supply.

Suction range or suction height is not only related to the pump, so it is not a parameter of the pump, so there is no such term and it is not specific. Suction height should be calculated according to cavitation allowance, pressure loss of suction device and local atmospheric pressure.

Question 9: How many meters can the maximum suction range of self-priming pump reach? It is the basis of power dispatching and power system planning. The load of power system involves all kinds of users in the vast area, and the electricity consumption of each user is very different, so it is impossible to know in advance when and where to increase the load. Therefore, the load change of power system is random. People use load curve to describe the change of load with time, and study the regularity of load change accordingly.

Question 10: What is the maximum suction range of the suction pump? Theoretically, the maximum suction range of the suction pump is 10 meter, which is exactly equivalent to the water column height at local atmospheric pressure.
