How does a micro gear pump work?

A micro gear pump is a small, simple hydraulic pump typically used in low-flow, high-pressure applications. Its working principle is as follows:

1.When the drive shaft of the micro gear pump rotates, the gear also rotates.

2.The space between the teeth of the gear constantly changes, creating negative and positive pressure areas.

3.In the negative pressure area, the liquid is sucked into the inlet of the gear pump.

4.In the positive pressure area, the liquid is compressed and discharged from the outlet of the gear pump.

5.The continuous rotation of the gear pump allows the liquid to be continuously sucked in and discharged, thus achieving the transportation of the liquid.

The micro gear pump has the advantages of small size, light weight, low noise, and long life, and is widely used in medical equipment, laboratory equipment, industrial robots and other fields.

What are the advantages of micro gear pumps? 

Micro gear pumps have the following advantages:

1. Wide application range: Micro gear pumps are suitable for conveying various liquids, including oil, water, chemical liquids, etc.

2. Stable flow rate: The flow rate of micro gear pumps is usually relatively stable, suitable for occasions with high flow rate requirements.

3. Low noise: The noise of micro gear pumps is usually relatively low, suitable for occasions with high noise requirements.

4. Long service life: The gears and bearings of micro gear pumps are usually made of high-quality materials, with a long service life.

5. Simple maintenance: The structure of the micro gear pump is relatively simple, and it is relatively easy to maintain.

It should be noted that the pressure and flow rate of micro gear pumps are usually relatively low, and they are not suitable for high-pressure and high-flow rate applications.

How to choose the right micro gear pump?

Choosing the right micro gear pump requires considering the following factors:

1. Flow rate and pressure: Select the model of the micro gear pump according to the flow rate and pressure of the fluid to be transported. It should be noted that the flow rate and pressure of the micro gear pump are usually relatively low and are not suitable for high flow rate or high pressure applications.

2. Fluid properties: Select the material and sealing method of the micro gear pump according to the properties of the fluid to be transported. Different fluids may have different requirements for the material and sealing method of the micro gear pump.

3. Working environment: Select the appropriate model according to the working environment of the micro gear pump. For example, in high temperature or corrosive environments, a micro gear pump with high temperature resistance or corrosion resistance is required.

4. Drive method: Micro gear pumps can be driven by electric, pneumatic or manual methods. The appropriate drive method needs to be selected according to actual needs.

5. Price and maintenance cost: The price and maintenance cost of the micro gear pump also need to be considered. The selection of the right micro gear pump needs to be based on the budget and maintenance cost.

In conclusion, choosing the right micro gear pump requires considering multiple factors and needs to be selected according to the specific application and requirements. It is recommended to consult a professional micro gear pump supplier before choosing to obtain better advice and help.
