Description
Technical field
The present invention relates to a kind of rotating detector transformational structure, belong to field of electromechanical technology.
Background technology
Locking type hydraulic damper is a kind of industrial pipeline support means, is all widely used in electrician, steel mill, chemical plant.This antivibrator under arms before to carry out two tests relating to load and speed parameter, one is the frictional resistance test under low speed, and two is the locking velocity test under rated load.Fig. 1 is the schematic diagram of antivibrator test system, and general oil cylinder, front stall maintain static, and on the basis of tailstock is bolted to a lot of or on the basis of employing pressure mechanism is fixed on, sensor is also screwed on tailstock to ten several bolts with several.Frictional resistance typically only allows between 1% 2% rated loads.Owing to two kinds of load magnitude differences are bigger, in testing at two, in order to ensure identical measuring accuracy, it is necessary to use the load transducer of different range, in low speed friction resistance test, i.e. use the sensor of small-range, the locking velocity test under rated load uses the sensor of wide range.The workload of more emat sensor is relatively large.
Current way is one sensors of large measurement range of installation on testing stand tailstock, then on sensors of large measurement range, concatenate a small-range sensor, first do low speed friction resistance test, small-range sensor is pulled down after finishing, again antivibrator is connected to sensors of large measurement range, does the locking velocity test under rated load.Also the method that the testing stand having uses is, first sensors of large measurement range is arranged on testing stand A tailstock, small-range sensor is arranged on testing stand B tailstock, when doing low speed friction resistance test, antivibrator is connected on the small-range sensor that is fixed on B tailstock, when doing the locking velocity test under rated load, small-range sensor and B tailstock are pulled down, is replaced with sensors of large measurement range and A tailstock.No matter which kind of method, is required for first antivibrator one end being taken apart, then disassembling sensor or replacing tailstock.Owing to dismounting antivibrator, disassembling sensor and replacing tailstock are all pretty troublesome things, thus result in that test job labor intensity is big, inefficiency.In some cases, such as nuclear power plant's periodic inspection, a large amount of antivibrators pulled down need test, and more emat sensor often to account for the testing time of more than 1/3rd, affects very much repair schedule.
