1. 12v centrifugal pump working principle.

The working principle of the 12v centrifugal pump is to use the rotation of the impeller to cause the centrifugal movement of the liquid to work. Before the 12v centrifugal pump is started, the pump casing and the liquid pipe must be filled, and then the motor is started, so that the pump shaft drives the impeller and the liquid to rotate at a high speed. The pressurized fluid line that flows into the pump. The size of its power consumption is proportional to the actual flow rate of the 12v centrifugal pump.

2. 12v micro vacuum pump working principle.

The working principle of the 12v micro vacuum pump is the circular motion of the motor. The diaphragm inside the 12v micro vacuum pump is reciprocated through mechanical equipment, so as to compress and stretch the air in the pump chamber of a fixed volume to form a vacuum (negative pressure), which is at the 12v micro vacuum pump exhaust port. There is a pressure difference between the place and the outside atmospheric pressure. Under the effect of the pressure difference, the gas is pressurized (sucked) into the pump cavity, and then discharged from the exhaust port.

3. 12v pneumatic diaphragm pump working principle.

The working principle of the 12v miniature pneumatic diaphragm pump is that the motor drives the oscillation of the eccentric wheel and the connecting rod, thereby driving the reciprocating motion of the diaphragm, forming a complete pumping motion with the valve plate of the air inlet and outlet. Not in direct contact with the corrosive material and liquid, and separating the cylinder cavity from the liquid material with a diaphragm is essentially the principle of the reciprocating pump.

4. 12v gear pump working principle.

The working principle of the 12v gear pump is composed of two gears meshing with each other. The teeth of the two gears are separated from each other to form a low pressure, and the liquid is sucked in and sent to the other side by the shell wall. On the other side, the two gears are closed together to form a high pressure to discharge the liquid. It relies on the volume change of the meshing space of the gear teeth to transport the liquid. It belongs to the rotary pump and can also be considered to belong to the positive displacement pump.

How to Choose a 12v Water Pump?

There are various 12v water pumps on the market, but not every 12v water pump can meet your requirements. This is because different 12v water pumps are suitable for different industries. Therefore, when selecting 12v water pumps, we should first clarify their scope of use, and then select different sizes, import and export forms and directions, different working performance, working environmental conditions, etc. according to the characteristics of 12v water pumps.   12v water pump with pressure switch

1. 12v water pump water head.

The maximum head of 12v water pump generally refers to the static head without water flow when pumping water to the maximum head. If it is necessary to pump to a certain height and maintain a certain flow, the required head must be higher than the specified pumping height. Generally speaking, when selecting the model, 12v water pump is necessary to increase the head to about 5% ~ 10% of the margin.

2. 12v water pump water flow.

Flow is one of the important performance data of 12v water pump selection, which is directly related to the pumping performance of the whole 12v water pump application system. Therefore, when selecting the 12v water pump, it should be based on the maximum flow and consider the normal flow. When there is no maximum flow, usually 1.1 times the normal flow can be taken as the maximum flow of the 12v water pump.

3. 12v water pump working environment.

If the environment in which the 12v water pump is used requires diving, such as in aquariums and fish tanks, the 12v water pump that can be used as a submersible pump must be selected. If the ambient temperature and working fluid temperature you need to use are very high, such as solar water heater, automobile engine heat dissipation, electric vehicle battery heat dissipation and other high water temperature environments, you must select a 12V water pump that can withstand high temperature. For example, 12v water pump with a maximum operating temperature of 100 ℃ shall be selected for the solar water heater, and an electric water pump with a maximum operating temperature of 180 ℃ shall be selected for the fuel cell cooling system of new energy vehicles.  

4. 12v water pump size and shape of water inlet and outlet.

When you choose 12v water pump for electrical appliances, equipment or water circulation system, you should choose 12v watr pump with appropriate external size. Therefore, it can be installed in the space of your design and left for the 12v water pump. If the remaining space of the 12v water pump is very compact, we recommend that you choose a 12v water pump with higher efficiency and smaller volume instead of other 12v water pumps with the same working performance. The direction and shape of the 12v water pump inlet and outlet should also be suitable for your piping system direction and joint type. For example, the inlet and outlet directions of 12v water pumps used on water heaters are usually in-line and threaded. In this case, you should choose a 12v water pump with 1/2 "or 3/4" threaded inlet and outlet.

The Application of 12V Water Pump in Chillers

The function of 12v water pump is mainly to circulate the liquid cooled inside the water chiller to other equipment that needs cooling, and then take the liquid with high temperature to the water tank for cooling. In this way, the continuous circulation and exchange of cooling can achieve equipment cooling. The application of 12v water pump in the water chiller is simply a circulation function. The application of Shenpeng 12V water pump in the chiller industry includes P6005 chiller circulating pump and P4504 chiller circulating pump.

The Application of 12V Water Pump in Water Heater

The 12V water pump is usually the most common in zero cold water heaters, because every time the water heater is turned on, the water heater needs to heat the cold water first, requiring a long waiting time of several minutes to tens of minutes. Many users cannot bear this waiting time. Zero cold water heaters solve this pain point through the working principle of the 12V water pump, and do not need to wait, just turn on and use. The working principle of a 12V water pump is to circulate hot water to other places where water is needed, and to maintain the temperature of the hot water area at all times to achieve the purpose of instant use.

What is the maximum pressure of the 12V high-pressure water pump?

The maximum pressure of a 12V high-pressure water pump depends on its design, size, and flow rate. Generally speaking, the nominal pressure of a 12V high-pressure water pump is generally between 20-100 bar (200-1000 Kpa), but it can actually exceed 200 bar (2000 Kpa), depending on the pump design and construction.

The 12V high-pressure water pump consists of an electric motor and a specially designed pump, and the pump design determines the pressure range of the pump. The maximum pressure of a 12V high-pressure water pump depends on the design of the pump's casing and internal components. Generally speaking, when using pumps with higher pressures, the casing and internal parts of the pump are designed to be more sturdy than pumps with lower pressures, in order to withstand higher pressures. In addition, the construction of the pump casing and internal components can also affect the maximum pressure of the pump, such as its volume and flow rate.

It is worth noting that when using a 12V high-pressure water pump, its output pressure should be adjusted according to the specific application scenario. If the output pressure is too high, it may cause damage to pipelines and equipment. If the output pressure is too low, it may affect its work efficiency. Therefore, when using a 12V high-pressure water pump, appropriate adjustments and controls should be made as needed to ensure its normal operation and achieve optimal performance.

In summary, the maximum pressure of a 12V high-pressure water pump depends on the pump design, size, and flow rate, which can be adjusted according to the pump design and actual needs, but generally does not exceed 200 bar (2000Kpa).
