Problems solved by technology
[0003] In special high-pressure metering pumps, especially in high-pressure physical property analyzers, due to the harsh requirements for the environment or experimental analysis conditions, the sealing performance of the sealing structure is also extremely strict; If the performance is not good or the sealing effect is not good, it will directly affect the effect and results of the whole experiment, and there will be errors in the analysis of experimental data.
The sealing device of the existing high-pressure physical property analyzer is generally sealed with a fluorine rubber sealing ring, and the sealing ring is squeezed and fixed by bolts to achieve the sealing effect. First, the sealing compression force of the sealing ring with this structure is uncertain, and the sealing compression bolts are not stable. It is convenient to adjust, and the fluororubber sealing ring is not resistant to high temperature, easy to corrode, and has a short service life, and the use of fluororubber sealing ring at high temperature is easy to cause sample contamination, which makes the sealing ring need to be replaced frequently and the replacement operation is complicated, which reduces the high-pressure physical property analysis. instrument reliability

Provided is a digital hydraulic adjustment sealing structure. A set of sealing rings is arranged below a sample tube of a high-pressure physical property analysis meter. A sealing adjustment rod is installed on the lower portions of the sealing rings. A fastening nut is arranged outside the sealing adjustment rod. An oil cylinder is arranged on the lower portion of the adjustment rod and connected to a hydraulic device. A high-pressure connector is arranged in the oil cylinder. The sealing structure is suitable for the fields of petroleum engineering, the petrochemical industry and the like.
Description
technical field [0001] The invention belongs to the technical field of sealing, in particular to a digital hydraulic adjustment sealing structure. Background technique [0002] Sealing technology is often used in anti-penetration or anti-leakage equipment, and it has also greatly promoted the development of industrial field equipment technology. Due to various industrial occasions or different environments or conditions, various special or special sealing structures have also been produced, that is to say, the sealing structures generally do not have universality or universality. [0003] In special high-pressure metering pumps, especially in high-pressure physical property analyzers, due to the harsh requirements for the environment or experimental analysis conditions, the sealing performance of the sealing structure is also extremely strict; If the performance is not good or the sealing effect is not good, it will directly affect the effect and results of the whole experi...
