Application of sofu NP series micro magnetic gear pump in cooling system

Application of sofu NP series micro magnetic gear pump in cooling system

Soufu NP series micro magnetic gear pump has the characteristics of no leakage, small flow, high pressure, wide temperature application range, low viscosity and gas-liquid two-phase liquid, dry operation, strong self-priming capacity, small influence of pressure on flow, and control accuracy of 0.5%. The performance characteristics of NP series make it widely used in many small cooling and refrigeration systems. NP series micro magnetic gear pump products have been successfully applied to traditional Freon R134a, r410, R141b, R245fa, r1233zd and various 3M fluorinated liquid systems.

Selection of pipe diameter of micro gear pump system

Selection of pipe diameter of micro gear pump system

When designing a large-scale system, the general user will pay attention to the selection of pipe diameter, but when it comes to the micro pump system, it is easy to be careless. At the same time, for the selection of pipe diameter of large industrial flow system, there are some clear specifications in some manuals. As long as the flow, temperature and viscosity are known, it is easier to select the appropriate pipe diameter. However, the minimum pipe diameter in these manuals is generally DN25, so there is no further subdivision. So how to select the appropriate pipe diameter for applications with a flow range of tens of milliliters to tens of liters per minute?

Why gear pump is not suitable for conveying media with particles

Why gear pump is not suitable for conveying media with particles

Generally speaking, gear pump is suitable for conveying liquid medium without solid particles. Gear pump is a positive displacement pump, which sucks and discharges liquid by the volume change generated in the process of rotating and meshing a pair of gears. If the gear needs to rotate, it means that there is a gap between the gear and the corresponding cavity. Because of the existence of these gaps, there will always be some liquid returning from the outlet high-pressure area to the inlet low-pressure area during the operation of the gear pump, which is the internal leakage of the pump. In order to reduce the internal leakage of the pump, the clearance between the gear and the cavity is very small. Generally speaking, the lower the viscosity of the transported liquid, the greater the pressure difference between the inlet and outlet, and the smaller the gap.

Why is it more suitable to use plastic gears for gear pumps conveying low viscosity liquids

Why is it more suitable to use plastic gears for gear pumps conveying low viscosity liquids

Many users have a mentality when choosing pumps. They always think that products like gear pumps are best metal gears. When they hear about plastic gears, they feel that the products are low-end and not durable. Here, I will briefly introduce the material selection of gear pump gear and bearing in low viscosity situations.

Precautions for selection of micro magnetic gear pump

Precautions for selection of micro magnetic gear pump

Micropumps usually refer to pumps with small volume and low flow. According to different technical principles, it can be divided into micro centrifugal pump, micro gear pump, micro diaphragm pump, micro plunger pump, micro peristaltic pump, micro vane pump, vortex pump, etc. according to the driving mode, it can be divided into direct connection type, magnetic drive type, reciprocating type and rotary type according to the movement mode, metal pump, plastic pump, composite pump, etc. according to the material, it can be divided into cryogenic pump High temperature pump and normal temperature pump can be divided into pneumatic pump, DC pump (12V, 24V, 48V, etc.), servo pump, AC pump, variable frequency pump, etc. according to different power sources. Users are often used to naming pumps according to their actual use needs, such as circulation pump, pressurization pump, sampling pump, cooling pump, urea pump, chromatography pump, flushing pump, atomization pump, etc. With so many subdivisions, it is inevitable to bring a lot of confusion to users in selecting pumps. Here, our company makes some analysis and suggestions based on the structure and performance characteristics of micro pumps and common applications for reference in selecting pumps.
