The invention provides a multifunctional testing loading detecting machine for a horizontal sleeve compensator and aims to solve the problems that no special detecting testing machine is provided for a domestic heat supply compensator, detection of related data is carried out only by universal detection equipment and inaccuracy of the data and detection parameters is easy to cause. The multifunctional testing loading detecting machine has the technical key points that a computer control system is connected with a testing loading platform; and a hydraulic station and a water pressure regulation control device are respectively fixed at both sides of the testing loading platform. The multifunctional testing loading detecting machine has the positive effects of large testing space, wide application and multifunctionality. The multifunctional testing loading detecting machine not only can be used for carrying out fatigue test on a single (double) sleeve compensator, but also can be used for carrying out unidirectional stretching and compressing test on the sleeve compensator, an expansion joint, a bellows and the like as required. The multifunctional testing loading detecting machine also has the characteristics of high control degree, low cost, stability, reliability, strong practicality and the like.
Description
technical field [0001] The invention relates to the field of physical parameter measurement of a sleeve compensator, in particular to a multi-functional test loading and testing machine for a horizontal sleeve compensator for testing a compensator with a relatively large stroke. Background technique [0002] In heating, in order to prevent the pipe from being deformed or damaged due to thermal elongation or temperature stress when the heating pipe is heated up, it is necessary to install a compensator on the pipe to compensate for the thermal elongation of the pipe, thereby reducing the stress and stress on the pipe wall. The force acting on the valve member or bracket structure. Since the heating compensator is a necessary part to maintain continuous heating in the pipeline, it is usually located at the joint of the pipeline, and the external situation is more complicated, so it is the most important to test its various performance indicators. There is no dedicated testing...
