A heating tube sealing test equipment

Abstract

The invention relates to heating tube sealing test equipment. The heating tube sealing test equipment comprises a machine frame. An operating deep groove is formed in the front end of the machine frame. The back face of the operating deep groove is connected with a high pressure water tank and a pipeline system. An overpressure protection mechanism is arranged at the detecting opening communicating the high pressure water tank and the pipeline system with the operating deep groove. A high pressure water compression system is arranged on the right side of the machine frame. The input end of thehigh pressure water compression system is connected with a water level compensation system, and the output end of the high pressure water compression system is connected with the high pressure watertank and the pipeline system. The machine frame is provided with a testing system connected with the high pressure water tank and the pipeline system, the high pressure water compression system, the water level compensation system. The testing system is connected with a thermal printer mounted in the machine frame and used for printing testing data, and a stabilized voltage source located in the machine frame. Operation is simple and application is convenient. Stability in the heating tube sealing testing process can be greatly improved. Automatic water compensation is achieved. The advantagesof adjustable testing time and pressure, high testing stability and high mounting factor are achieved.

Description

technical field [0001] The invention relates to the technical field of heating tube testing, in particular to heating tube sealing testing equipment. Background technique [0002] When the heating tube is tested for tightness, the existing test equipment is a split assembly equipment. The equipment uses a hydraulic test box, pressurization equipment, and a stopwatch. During the test, the heating tube needs to be placed in the hydraulic test box, and the nut must reach the corresponding torque. ;It is necessary to manually turn the open water valve to release water, and then manually close the water discharge after the end. The air pressure in the cylinder must reach 2MPa; because the pressure of the box and pipeline must reach a certain high pressure during the test, the heating tube is installed in the test box and the unstable pressure shocks out of the box. In vitro, it is easy to cause safety hazards; and the water in and out of the test box needs to be manually controll...

In vitro, it is easy to cause safety hazards; and the water in and out of the test box needs to be manually controlled, and the test time needs to be tracked manually. The operation is cumbersome, which is not conducive to testing
