What is the miniature pump? The pump is generally composed of the drive part of the pump body, the pump body has one into and out of two interfaces, the water inlet and outlet from the water, all in this form, and Small size, pocket pumps, are called micro-pumps, also known as micro-pump. Micro-pump on the market there are many micro-pumps, micro-liquid pumps, small pumps, pumps, self-priming pumps, how to choose the right model? Micro pump main parameters are: "flow", "pressure" When exactly according to what criteria to choose it? Xiaobian order for everyone, you can choose according to the following principles. (A), working medium at room temperature (0-50 ℃), simply pumping water or solution, not water and gas dual-use, but requires self-absorption capacity, and the flow and output pressure requirements. Description: Pumping the working medium is water, non-oily, not strong corrosive liquid solution (can not contain solid particles, etc.), there must be self-priming function, you can choose the following pumps: ⒈ flow requirements (about 4 ~ 20 liters / Min), the pressure is not demanding (about 1 to 3 kg) is mainly used for water circulation, water sampling, upgrading, etc., requiring noise, long life, high self-priming suction, etc., the optional BSP, CSP and other series; Low flow requirements (about 1 to 5 liters / minute), but the pressure (about 2 to 11 kg) to be used for spraying, pressurization, car washing, etc. do not need long hours of work under high pressure or heavy load, you can Select ASP, HSP and other series; ⒊ for tea table pumping, spraying, etc., requires the volume as small as possible, the flow requirements of small, low noise (about 0.1 to 3 liters / minute), optional ASP and other series. (B), the working medium at room temperature (0-50 ℃), the need for pumping water or gas (may be mixed water or air, dry turn occasions), value the volume, noise, continuous use and other properties. Description: Requires water and gas dual-use, long-term dry turn, without damaging the pump; 24 hours of continuous operation; Small size, low noise, but the flow, pressure less demanding. ⒈ micro-pump or pump vacuum, but sometimes there will be liquid water into the pump chamber. ⒉ requirements of micro-pump both pumping and pumping.微 Use a mini pump to pump water, but in some cases it may pump without water and be "dry to". Some traditional pumps fear "dry turn", "dry turn" can even damage the pump. The PHW, WKA series of products is essentially a composite function pump ⒋ mainly micro-pump pumping, but do not want to manually increase the "water diversion" before pumping (some pumps need to manually add some "water diversion" before work, so that the pump can The lower part of the water pumping up, or the pump can not pump or even damage), that is, I hope the pump has "self-absorption" function. At this point you can choose PHW, WKA series products, their strength is that: In the absence of access to water, it is a vacuum, the formation of a vacuum by air pressure up, and then began pumping. With the above application, you can choose PHW, WKA series. (C), high temperature working medium (0-100 ℃), such as miniature pumps for water circulation cooling, water cooling, or pumping high temperature, high temperature steam, high temperature liquid, you must use a miniature pump (high temperature type) ⒈ temperature: 50-80 ℃, you can choose micro-water dual-use pump PHW600B (high temperature medium type) or WKA series of high temperature medium type, the maximum temperature is 80 ℃ or 100 ℃ temperature; ⒉ temperature: 50- 100 ℃, you must choose WKA series of high temperature medium type, the maximum temperature is 100 ℃ temperature; (when the extraction of high temperature water (water temperature exceeds about 80 ℃), due to the precipitation of gas in the water, will greatly reduce the pumping flow, Specific to reduce the amount of traffic, please refer to: (This is not a pump of quality problems, please pay attention to the selection!)) (D), the flow of greater demand (more than 20 liters / minute), but the medium contains a small amount Oil, solid particles, residues and so on. Description: ①pumping medium: ⒈ contains a small number of smaller soft solid particles (such as fish feces, sewage sludge, residue, etc.), but the viscosity can not be too large, and it is best not to have a hair (2) allow the working medium containing a small amount of oil (such as a small amount of oil floating on the surface of the sewage), but not all oil! (2) flow requirements (more than 20 liters / minute): 1, do not need self-absorption For applications where the pump can not be put in water, the solid particles can be cut into smaller particles: the FSP Ultra Flow series can be selected. 2, Need to self-priming, and the pump can be placed in the water, the optional mini submersible pump QZ (in the flow of 35-45 liters / minute), QD (large flow 85-95 liters / minute), QC L / min) three series of mini submersible pumps, DC submersible pumps.
