Problems solved by technology

[0003] However, the design principle adopted by ultra-high-pressure fluid metering pumps capable of achieving pressures above 200 MPa is that the output flow rate is higher than the leakage flow rate to meet the demand for pressurization. This design cannot meet the above-mentioned ultra-low flow rate application requirements.

Abstract

The invention provides a metering pump. The metering pump comprises a seawater bottle (1), an ultrahigh pressure pump (2), a micro-flow metering pump shell (6), a temperature controller heat exchangecabin (7), a temperature controller host (9), a deep sea microorganism culture kettle (10) and a waste liquid bottle (12). A water suction port of the ultrahigh pressure pump (2) is connected with anoutlet of the seawater bottle (1). A water outlet of the ultrahigh pressure pump (2) is connected with an inlet of the micro-flow metering pump shell (6). A temperature controller heat exchange cabin(7) is arranged on an outer side of the micro-flow metering pump shell (6). The temperature controller heat exchange cabin (7) is connected with the temperature controller host (9) through a pipeline.The outlet of the micro-flow metering pump shell (6) is connected with the inlet of the deep sea microorganism culture kettle (10) through the pipeline. The outlet of the deep sea microorganism culture kettle (10) is connected with the waste liquid bottle (12) through the pipeline. The micro-flow metering pump shell is pre-pressurized through a conventional high-pressure pump, and pumping efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of metering pumps, in particular to a metering pump. Background technique [0002] Research on the geological, chemical, and biological processes of the deep sea and deep ground is an international frontier hotspot and focus, and has a decisive impact on the improvement of national territorial security, strategic resource reserves, and basic research capabilities. Simulating the deep-sea and deep-ground environment in the laboratory and reproducing the dynamic process in it is currently the preferred research strategy in this field, which has the advantages of low cost, high controllability, strong reliability, and good repeatability. High pressure, even ultra-high pressure, is the most typical feature of the deep sea and deep ground environment, and it is also one of the most critical parameters for environmental simulation. It has been reported that deep-sea organisms can grow under a pressure of more tha...
