Problems solved by technology

At this stage, most of these micropumps are made of plastic or metal, especially their external gas inlet and outlet; from the above we can also see that whether it is a diaphragm pump, a miniature electromagnetic pump or a peristaltic pump, the gas needs to contact the pump chamber. For diaphragm pumps and peristaltic pumps, their diaphragms or hoses are soft and should not withstand harsh pressure conditions
[0004] In summary, there are some problems in the micro gas pump at this stage: it is not easy to connect with the glass device, so that the airtightness of the whole system is poor; it is in contact with a variety of experimental gases, and its corrosion resistance is poor; or due to its poor pressure bearing or There is gas overflow, it is not suitable to operate under severe pressure conditions

Abstract

The invention discloses a glass magnetic piston pump. The invention comprises a glass part and an electromagnetic driving part. The glass part: a glass piston is installed in the glass pump body, a magnetic core is fixed in the glass piston, and the left end of the glass pump body is connected to a glass combined unidirectional pump body. The glass grinding port on the valve, the right end of the glass pump body is connected with the glass interface of the glass combined check valve; the glass pump body passes through the first electromagnetic coil and the second electromagnetic coil of the electromagnetic drive part. The invention is used to drive gas circulation, has good air tightness, is easy to connect with glass devices, and can operate under relatively high negative pressure.

Description

technical field [0001] The invention belongs to a gas driving device, in particular to a glass magnetic piston pump. Background technique [0002] In the laboratory, many reaction tests are carried out in glass instruments. For the process involving gas, many need to make it flow or circulate, and most of them are carried out at a small flow rate, so it is necessary to choose a suitable micro gas Drive the pump. [0003] Micro gas pumps currently used mainly include diaphragm pumps, micro electromagnetic pumps and peristaltic pumps. The principle of the diaphragm pump is that through the expansion and contraction of the diaphragm, the volume of a certain cavity is periodically reduced and expanded, causing the change of the gas pressure in the cavity, and then combined with the one-way valve to drive the directional movement of the gas; the principle of the micro electromagnetic pump is also the same as that of the diaphragm. The pump is similar, but the piston is driven t...
