How long is the life of CNHT micro pump? How to measure the life value?


In the micropump industry, there is no uniform specification when the product life is nominal. According to the internal specification, the motor, material, bearing, structure, load, etc. used usually vary from millions of hours to tens of thousands of hours according to the product life, motor life, machine life, working life, etc


Generally, the manufacturer adopts the test method of "full life of continuous operation under maximum rated load" during the rated life: the life obtained in the worst working condition under maximum load and continuous 24-hour working test.

In addition, the pump of the same model can be divided into three different versions. The simplified version, standard version, quality version and version have different life spans. Generally speaking, the simplified version has a service life of more than 2500 hours, the standard version has a service life of more than 6000 hours, and the quality version has a service life of more than 9000~10000 hours. It is a highly reliable product that can run continuously for a long time.

It is worth noting that the tests of general manufacturers are tested and marked in the worst case. Therefore, if the customer uses the CNHT micropump under small load and intermittently, the service life will be greatly increased, and the actual service life will be increased by more than 2-3 times.

CNHT micro pump only needs positive number or solution, has self suction, and has requirements for flow and output pressure. Usually lift, transport or apply pressure to liquids. In other words, the machines that convert the mechanical energy of the original motor into liquid energy and pump out liquid are collectively referred to as pumps.

A pump is a machine for transporting liquids or pressurized liquids. It increases liquid energy, transfers the mechanical energy or other external energy of the original motor to the liquid, and is mainly used to transport liquids, such as water, oil, acid-base liquids, lotion, suspended lotion, liquid metals, etc. It can also transport liquids containing liquids, gas mixtures, and suspended solids.

The positive displacement pump of CNHT micropump uses the volume change of the working chamber to transfer energy. Vane pump uses the interaction of rotating blades and water to transfer energy, including centrifugal pump, axial flow pump, mixed flow pump, etc. The centrifugal pump can be divided into AC pump, painting DC pump, brushless DC motor pump and brushless DC magnetic separation pump according to the control principle.

CNHT micro pump has the following advantages:

1. Long service life, maintenance free, small size, high efficiency, low power consumption, strong anti-interference ability and smooth operation. 2. No carbon painting, no pollution, electronic rectification, long service life. 3. The stator and circuit board of the motor are completely isolated from the rotor by transplanting epoxy Pei Xiuzhi, which solves the leakage problem caused by long-term diving of the motor type DC pump. It can be installed underwater and is completely waterproof.
