Abstract

The invention provides a shielded precision injection pump, which includes a host computer, a control unit, an execution unit, and a DC power supply; the shielded precision syringe pump in this scheme adopts a control unit and an execution mechanism composed of shielding materials, and the control unit and the execution mechanism The cables between the DC power supply and the host computer are also made of shielded and corrosion-resistant materials; and the data communication between the control unit and the actuator, the DC power supply, and the host computer are also connected by aviation sockets. Connection, so the whole device can have good shielding performance and can be used in strong radioactive places.

Description

technical field [0001] The invention relates to the technical field of nuclear fuel radiation, in particular to a shielded precision injection pump. Background technique [0002] In the nuclear fuel reprocessing process test, the hot chamber is a strong radioactive area with high radiation intensity, and ordinary feed pumps cannot work in this environment for a long time. Among them, the precision feeding pump has been troubled by the development of radioactive experiments in hot chambers for many years. According to market research at home and abroad, there is no high-precision feeding equipment that can meet the requirements of strong radioactive places. [0003] Therefore, it is particularly important to find a technical means of a syringe pump that can complete the process test task in a radioactive place and has a reliable precision. Contents of the invention [0004] In view of the defects in the prior art, the purpose of the present invention is to provide a shield...
