How Is The Miniature Water Pump Defined

First of all, we need to know what is the micro pump, micro pump usually lift liquid, liquid delivery or liquid increase pressure, that is, the prime mover mechanical energy into liquid energy to achieve the purpose of pumping liquid machine collectively referred to as the pump, the pump is generally composed of driving part + pump body, pump body has an inlet and outlet two interfaces, water from the inlet into, drain out, Usually in this form, and small size, pocket pump, are called micro pump, also called micro pump.

Now there are many micro pumps, micro pumps, micro vacuum pumps, how to select the type, the main parameters are flow, pressure or head, whether the need for self-priming and so on. The selection should be selected according to the specific requirements.

First, only pumping or solution is required to have self-priming capacity, and the flow rate and output pressure are required.

Description: The working medium of pumping is water, non-oily liquid solution (can not contain solid particles, etc.), self-priming function, you can choose the following pump: 1, the flow requirement is large (about 4 ~ 20 liters/min), the pressure requirement is not high (about 1 ~ 3 kg), mainly used for water circulation, water sampling, lifting, small noise, long life, high self-priming suction range, optional BSP, CSP series; 2, the flow requirement is not high (about 1 ~ 5 L/min), but the pressure is large (about 2 ~ 11 kg), mainly used for spray, pressurization, car washing and so on do not need to work for a long time under high pressure or large load, you can choose ASP, HSP series; 3, used for tea table pumping, kung fu tea pumping, spray, etc., the required volume is as small as possible, the flow requirement is small, the noise is small (about 0.1 ~ 3 L/min), optional PHW, ASP series.

Second, the need to pump or gas, value volume, noise, continuous use and other performance description: requirements of water and gas dual use, can be long-term dry rotation, no damage to the pump; 24 hours continuous operation; Especially small volume, low noise, but the flow, pressure requirements are not high.

1. Use a micro pump to pump air or vacuum, but sometimes liquid water will enter the pump chamber.

2, the micro pump can be pumped and pumped.

3, with the micro pump pumping, but sometimes the pump may have no water to pump, in a dry state.

Some conventional pumps are afraid of dry running, which can even damage the pump. PHW series products are essentially a kind of composite function pump, it integrates the functions of vacuum pump and water pump, some people call it vacuum pump. So in the absence of water, it vacuums, and it pumps when water is available. Both pumping state and pumping state belong to the normal working category, so there is no dry rotation damage.

4, mainly with micro pump pumping, but do not want to pump before artificial water (some pumps need to add some artificial water before work, so that the pump can pump the low water, otherwise the pump can not pump or even damage), that is, the pump has self-priming function. At this time, the strength of PHW series of products is that when there is no contact with water, it is pumped, formed after the vacuum pressure to water up, and then began to pump.

PHW series can be selected when the above applications are available.

Third, the flow has a larger requirement, the medium contains a small amount of oil, solid particles, residue and so on.

Description: In the medium to be pumped.

1. Contain soft solid particles with diameter less than 31mm (such as hair, fish feces, sewage sludge, residue, etc.), and can be cut into smaller particles, but the viscosity should not be too large!

2. Allow the working medium to contain a small amount of oil (such as a small amount of oil floating on the sewage surface), but not all oil!

3. large flow requirements, do not need the occasion of self-priming function
