Problems solved by technology
The disadvantages are: on the one hand, there is a possibility of internal oil leakage in this method, which will affect the in-situ environment near the analysis point, and the breeding of microorganisms will cause corrosion and damage to the equipment; on the other hand, the quantitative control of the oil-filled peristaltic pump The method is completed by controlling the working time, and the additional resistance under different water pressures will affect the motor speed, thereby affecting the displacement accuracy of the chemical reagents

The invention discloses a deep sea peristaltic pump which comprises a peristaltic pump head, an output shaft, a pressure resistance barrel, a direct current gear motor and a magnetic induction switch.A shell of the peristaltic pump head is connected with the pressure resistance barrel, a rotating portion of the peristaltic pump head is fixedly connected with one end of the output shaft, the otherend of the output shaft is connected with a rotating shaft of the direct current gear motor through a coupler, a magnet of the magnetic induction switch is arranged on the coupler, an induction coilof the magnetic induction switch is arranged at the position, matched with the magnet, inside the pressure resistance barrel, the magnetic induction switch is used for feeding back the rotating circlenumber of the peristaltic pump head to a controller, and the controller is electrically connected with the direct current gear motor. The invention further discloses a deep sea controllable long-termchemical reaction device comprising the deep sea peristaltic pump. According to the deep sea peristaltic pump and the deep sea controllable long-term chemical reaction device, the displacement precision is not affected by the water depth, and the displacement precision of chemical reagent can be improved.
Description
technical field [0001] The invention relates to the technical field of deep-sea quantitative control chemical reaction, in particular to a deep-sea peristaltic pump and a deep-sea controllable long-term chemical reaction device. Background technique [0002] The research on deep sea life science and biogeochemistry is the frontier at present. Since the deep sea is a harsh environment with high pressure, darkness and low temperature, the deep sea detection and observation equipment has great limitations, which hinders the development of deep sea scientific research. At present, most The deep-sea in-situ data comes from the direct perception and observation of various sensors. As we all know, many parameters can only be analyzed after chemical reactions. Therefore, in-situ analysis equipment with chemical reaction systems is an indispensable equipment for deep-sea scientific research. [0003] The deep-sea peristaltic pump that adds liquid regularly and quantitatively is the c...
