Abstract

The invention discloses a calibration system. The calibration system includes a calibration station for fixing the first end of a test bolt and providing support for a tensioner; a pump station for providing hydraulic pressure for the tensioner; a pressure sensor for measuring the hydraulic pressure; a force sensor for measuring a force applied by the tensioner to the test bolt; a controller for calculating a force applied by the pump station to the tensioner according to the hydraulic pressure measured by the pressure sensor, and comparing the force applied by the pump station to the tensioner with the force measured by the force sensor. According to the embodiment of the invention, the system can guarantee the precision of the tensioner and the stretching pump of the tensioner, and guarantees the bolt connection strength and reliability.

Description

technical field [0001] The present invention generally relates to the field of calibration equipment, and more specifically, relates to a calibration system for calibrating a stretcher or a stretcher and its stretching pump station. Background technique [0002] The hydraulic tensioner usually determines the tensile force according to the tensile strength, yield coefficient and elongation of the bolt. With the help of the hydraulic source provided by the hydraulic pump station, the bolt is elongated in its elastic deformation zone and the nut is loosened, so that the bolt can be stretched. The purpose of pre-tightening or dismantling bolts. At present, hydraulic tensioners have been widely used in petrochemical, nuclear power, wind power, hydropower, thermal power, ships, railways, aerospace, mining, heavy machinery and other fields. [0003] However, with the widespread application of hydraulic tensioners, their construction accuracy directly affects the strength and relia...
