Precautions for selection of micro magnetic gear pum
Precautions for selection of micro magnetic gear pum
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.

Why gear pump is not suitable for conveying media with particles
Why gear pump is not suitable for conveying media with particles
一般来说,齿轮泵适合输送不含固体颗粒的液体介质。 齿轮泵是一种容积泵,靠一对齿轮旋转啮合过程中产生的容积变化来吸入和排出液体。齿轮需要旋转,那么就意味着齿轮和对应的腔体之间是存在间隙的。正是由于这些间隙的存在,在齿轮泵工作时总会有一部分液体从出口高压区返回到入口低压区,这就是泵的内部泄漏。为了减小泵的内部泄漏量,齿轮和腔体之间的间隙是很小的。通常来说,输送的液体粘度越低,进出口压差越大,那么这个间隙就越小。

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?
