Micro fountain pump

Micro fountain pump DC micro fountain pump types:

1, brush DC fountain pump 2, brushless DC fountain pump (motor type)

3, brushless DC fountain pump (magnetic drive isolation type) (Shenzhen Zhongke Century Technology)

Three DC fountain pump features:

1. Brushed DC fountain pump: When the pump works, the coil and commutator rotate, and the magnet and carbon brush do not turn. The alternation of coil current direction is accomplished by the commutator and brush that the motor rotates, as long as the motor Turning the carbon brush will cause wear. When the computer water pump runs to a certain time, the carbon brush wear gap will become larger and the sound will increase. After a few hundred hours of continuous operation, the carbon brush will not be able to play the role of commutation.

Advantages: low prices.

2. Brushless motor type DC fountain pump: The motor type brushless DC pump is composed of a brushless DC motor plus an impeller. The shaft of the motor is connected with the impeller. There is a gap between the stator and the rotor of the water pump. Water will penetrate into the motor for a long time and the motor will burn out easily.

Advantages: Brushless DC motor has been standardized, there are a large number of specialized manufacturers to produce, the cost is relatively low, high efficiency.

3, brushless DC magnetic drive fountain pump: brushless DC water pump adopts the electronic component commutation, without the use of carbon brushes for commutation, the use of high-performance wear-resistant ceramic shaft and ceramic sleeve, the sleeve through the injection and the magnet is also integrated Since wear is avoided, the life of brushless DC magnetic pumps is greatly enhanced. The stator part and the rotor part of the magnetic isolation pump are completely isolated. The stator and the circuit board part are encapsulated with epoxy resin, 100% waterproof. The rotor part uses permanent magnets. The pump body is made of environmentally friendly materials, low noise, small size, and performance. stable. The stator windings can be used to adjust various desired parameters, allowing wide voltage operation.

Advantages: Long life, low noise up to 35dB, can be used for hot water circulation. The stator and circuit board part of the motor are encapsulated with epoxy resin and completely isolated from the rotor. It can be installed underwater and completely waterproof. The axis of the pump adopts high-performance ceramic shaft, which has high precision and good shock resistance. The difference between brushless motors and brushed motors (1) It is not easy to produce high temperature arcs and metal shavings when switching.

(2) Low electrical noise, high reliability, long life, and high speed.

(3) Low voltage, quick start, easy control.

(4) easy to manufacture, small size.

(5) Applicable to high temperatures and low maintenance costs.

(6) No dirt such as toner, oil mist, etc. is generated in the brush portion.

(7) No electrical noise (no electrical interference).

(8) No spark.

(9) Do not flash over.

Micro-pumps, micro-pumps, liquid sampling pumps, small pumps, DC pumps 1. Main features: Ultra-small volume (smaller than the palm of the hand); Unique dual-purpose water and gas function, the working medium can be gas and liquid (non-oil , No strong corrosion), water pumping, gas pumping;
