12v water pump

12v water pump refers to a miniature water pump powered by 12V DC power supply. It can be powered by a switching DC stabilized power supply, or connected to a car battery for power supply, and can also be powered by a solar panel, which is quite convenient to use. Compared with AC water pumps, it has a wider range of use and is safer. 12v water pump is very widely used, because of its small size, low noise, low power consumption and other advantages, it can be widely used in water circulation, cooling, lifting, transfer, pressurization, spraying, spraying, water circulation, transportation and other purposes.

12v water pump can be divided into different categories: 12v diaphragm pump, 12v centrifugal pump, 12v gear pump, 12v pneumatic diaphragm pump, etc.

R & D, design and production of 12v water pump

Dongguan Shenpeng Electronics Co., Ltd was found in 2012 and is specialized in brush-less DC water pumps. As a global BLDC water pump solutions specialist, it integrates R&D, manufacture with sales.The products are mainly applied to New-energy vehicle, mattress, home appliance (water heater, dish washer, coffee machine, water dispenser), smart toilet, cosmetic/medical equipment, machine tool equipment, air conditioning base station, PC, LED cooling system, aquarium etc.

Shenpeng was the earliest company that managed to produce the brushless DC water pumps. It is located in Changping, Dongguan and covers an area of 18000㎡. With an in-house CNAS standard laboratory, 300-thousand-grade dust-free workshop and 10 professional production lines. The annual production capacity is more than 5 million sets of water pumps and it is one of the largest manufacturer of BLDC water pump in China. It won many honorable titles such as High-tech Enterprise, Multiplication Enterprise etc.

How does the 12v water pump work?

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 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 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 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 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.

Application scope of 12v water pump?

12v water pump has a wide range of applications: it can be used in the automotive industry, water heaters, smart toilets, dishwashers, plumbing mattresses, coffee machines, industrial chillers, laser machines, printers, air conditioning equipment, computers, washing machines, medical beauty equipment, humidifiers , Sweeper, water dispenser, soilless cultivation, aquarium, solar fountain, household tap water pressurization, car washing, seawater desalination on ships, reverse osmosis pure water machine, water treatment equipment, filter, spray device, chemical metering liquid and Sanitation, environmental protection, printing and other industries.

How to Choose a 12v Water Pump?

There are various 12V pumps on the market, but not every pump can meet your requirements. This is because different pumps are suitable for different industries. Therefore, when selecting 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 pumps.

1. 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, it is necessary to increase the head to about 5% ~ 10% of the margin.

2. water flow.

Flow is one of the important performance data of pump selection, which is directly related to the pumping performance of the whole pump application system. Therefore, when selecting the DC 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. working environment.

If the environment in which the 12V pump is used requires diving, such as in aquariums and fish tanks, the 12V 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, a 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.

5. size and shape of water inlet and outlet.

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

Characteristics of 12v water pump.

1. 12V water pump generally refers to 12V DC power supply. Switching DC regulated power supply can be used for variable voltage power supply, vehicle battery can also be connected for power supply, and solar panel can also be used for power supply, which is very convenient to use. Compared with the AC water pump, it has a wider range of use and is safer.

2. compared with 24V water pump or 48V water pump, 12V water pump is quieter and has lower power.

3. compared with the AC water pump, the DC water pump is more safe, with exquisite workmanship, small volume, light weight, stable performance and convenient installation.
