The principle of quiet water pump and the standard of options

Mute pump refers to the minimum noise of micro pumps. Micro pumps possess a into a flush and drain a mouth, and in the inlet can continue to form a vacuum or negative pressure; Larger output pressure drain; Working medium is water or liquid. An instrument of small size.

Micro pump has called "the micro liquid pump, mini pump, mini pump". Micro pump noise is not only from the motor power, and there are water and pipe wall friction noise, now some miniature pump noise is fairly small, basic can be called a mute pumps. Such as in micro self-priming pump, water dual-use WKA series, the flow in the series of CSP, and micro QZ series pump noise is very small.

What mute pumps and micro pumps in accordance with the criteria for selection? You can choose according to the following principles.

A. Working medium under normal temperature (0-50 ℃), need water or gas (water mixing or idling, dry turn), value performance, such as volume, noise, continuous use.

Description: require moisture dual-use, can turn dry for a long time, no damage to the pump; 24 hours of continuous operation; Small volume, low noise, but for flow and pressure requirements is not high.

1. With the micro pump suction or pumping air into vacuum state, but sometimes there will be a liquid water into the pump chamber.

2. Require to extraction and micro pump pumping.

3. Use the micro pump pumping, but sometimes may pump can smoke without water, in a state of "dry".

Some traditional pump fear "dry", "dry" may even damage the pump. And PHW, WKA series products is essentially a kind of compound function pump, it integrates the function of the vacuum pump and water pump, some people call it "vacuum pump. Therefore, in the absence of water, it will vacuum, there is water when it is pumped. Both in extraction condition and pumping condition, belong to the category of the normal work, and you can't have "dry" damage.

4. Main use micro pump pumping, but don't want to in front of the water by artificial add "diversion" (some pump before work need artificial add some "pilot", in this way can pump the water pumped, lower pump can't flush and even damage), namely, hope to have the self-priming pump function. Then can choose PHW, WKA series products, their strengths is that without access to water, it is vacuum, vacuum formed by pressure after the water pressure, and then began to flush
