What Types Of Micro Pumps?

Micro pump transport liquid or make the liquid pressurized machinery, it will be the mechanical energy of the prime mover or other external energy transmission to the liquid, make the liquid energy increase, mainly used to transport liquid including water, oil, acid and alkali, emulsion, suspension emulsion and liquid metal. It can also deliver liquids, gas mixtures, and liquids containing suspended solids. Small size, the general form of the drive part + pump body, pump body has one into one out of two interfaces, water from the inlet, drainage outlet.

DC micro pump can be divided into DC micro pump and DC brushless micro pump through the different motor commutators in the pump; DC micro pump uses brushed motor with large torque, so the flow, suction and pressure can be relatively high; DC brushless micro pump is composed of brushless DC motor and impeller. The shaft of the motor is connected with the impeller, and there is a gap between the stator and rotor of the pump. After the use time, the water will penetrate into the motor, increasing the possibility of the motor burning out. According to the principle can be divided into diaphragm type, piston type, gear type and other micro pumps.

To facilitate regulating the output flow of the pump. Through the electronic control mode to change the motor speed to change the flow rate, easy to achieve automatic control, is conducive to noise reduction, shock absorption, energy saving. Compared with the mechanical valve to change the flow is more suitable for automatic control, better adjustment accuracy, lower cost. There is a motor speed feedback signal. Through the feedback signal, the running state of the pump and the change of the pump output flow can be known to realize intelligent control. With overheating protection, overload protection function. When the environment is overheated beyond the bearing limit of the pump or a foreign body is stuck, the pump will automatically stop from my protection to avoid damage. Maintenance-free, no oil and lubrication. No oil in the pump, do not pollute the transmitted gas. Gas extraction is allowed. It can be installed in any direction and work normally. For example, installed on the horizontal plane, vertical plane, inclined plane, can work normally. Low noise. Allow the extraction of corrosive gas (gas contact material: Medial polystyrene resin, EPDM rubber).
