The structure of the dehydration meter mainly includes the following parts:
Base assembly: It is composed of a base and a bracket, etc., and is the supporting assembly of the instrument.
Drilling fluid cup assembly: It includes a drilling fluid cup body, a cup cover, a filter, a compression screw and a compression knob, etc., which are used to hold the measured liquid.
Pressure reducing valve assembly: It is composed of a valve seat, a valve core, an input and output joint, a pressure regulating handle, a valve body, a valve stem, etc. It is a high-pressure pressure reducing device used to provide the pressure required for the experiment.
Air source device: Usually an air source (such as an air pump) and a pressure reducer are used to provide the air pressure required for the experiment.
Graduating cylinder: It is used to receive filtrate and measure the amount of filtrate.
Heating system: It includes a heating sleeve, etc., which is used for testing under high temperature and high pressure conditions.
Specific structural differences of different types of dehydration instruments
Quadruple high-temperature and high-pressure dehydration instrument (such as GGS424A): This dehydration instrument has four high-temperature and high-pressure dehydration instruments, which can test four samples at the same time. It includes components such as the main unit and the heating system, and is suitable for simulating the filtration loss test of drilling fluid and cement slurry under deep wells (high temperature and high pressure).
Low-temperature and low-pressure dehydration instrument (such as OFITE 500ml): This dehydration instrument is mainly used to simulate the filtration loss and filter cake formation characteristics of drilling fluid under low-temperature and low-pressure conditions. Its structure includes a base assembly, a drilling fluid cup assembly, a pressure reducing valve assembly, an air source device, and a measuring cylinder, etc.
