Description

Technical Field

[0001] This utility model relates to the field of thickening instrument technology, specifically a split-type pressurized thickening instrument. Background Technology

[0002] Due to the different locations of application, cement properties need to be tested, and a pressure thickener is a commonly used testing device. Pressure thickeners can be used for research on oil well cement and its admixtures, as well as for cement manufacturers to control and inspect cement quality. The equipment is typically equipped with a high-speed rotating paddle and a fixed paddle sensor. Users define the temperature and pressure conditions of the test chamber, and the cement properties under different conditions are tested through sensor measurements. Pressure adjustment is required using the pressure thickener. However, currently, pressure adjustment is mainly achieved by injecting air into the instrument using a syringe principle. The piston first draws in air, and then pushes the air into the instrument. Therefore, the piston only has a single-pass air injection function, resulting in a slow pressure adjustment speed.
