Description
Technical field
The present invention relates to a kind of rotating detector transformational structures, belong to field of electromechanical technology.
Background technology
Locking type hydraulic damper is a kind of industrial pipeline support device, has in electrician, steel mill, chemical plant and answers extensively
With.This damper will carry out two tests for being related to load and speed parameter before serving, first, the friction resistance under low speed
Power is tested, second is that the locking velocity experiment under rated load.Fig. 1 is the schematic diagram that damper tests system, general oil cylinder, front stall
Fixed, on the basis of being fixed on the basis of tailstock is fixed on many bolts or using pressure mechanism, sensor is also used
Several to more than ten bolt is screwed on tailstock.Frictional resistance typically only allows between 1% -2% rated load.Due to two kinds of loads
Lotus magnitude difference is larger, in being tested at two, in order to ensure identical measuring accuracy, it is necessary to using the load sensing of different ranges
Device uses the sensor of small-range that is, in low speed friction resistance test, using big in the locking velocity experiment under rated load
The sensor of 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, is then gone here and there on sensors of large measurement range
A small-range sensor is connect, low speed friction resistance test is first done, small-range sensor is removed after finishing, then damper is connected
To sensors of large measurement range, the locking velocity experiment under rated load is done.Also the method that the testing stand having uses is, first wide range
Sensor is mounted on testing stand A tailstocks, small-range sensor is mounted on testing stand B tailstocks, does low speed friction resistance test
When damper is connected on the small-range sensor being fixed on B tailstocks, do under rated load locking velocity experiment when,
Small-range sensor and B tailstocks are removed, sensors of large measurement range and A tailstocks are replaced with.No matter which kind of method, be required for first
Damper one end is dismantled, then disassembling sensor or replacement tailstock.Since dismounting damper, disassembling sensor and replacement tailstock are all
Pretty troublesome thing, therefore cause that test job labor intensity is big, working efficiency is low.In some cases, for example nuclear power plant is regular
Maintenance, a large amount of dampers removed need to test, and more emat sensor will often account for the testing time of one third or more, very
Influence repair schedule.
