Abstract
The utility model relates to a rotation test device for a vertical wheel disc. The device comprises a casing, a test piece, and a rotation axis and an oil receiving box which are arranged in the casing, wherein a power plant and an oil thrower wheel are arranged on the rotation axis, the oil receiving box is connected with a sensor, the key point is that a filtering cover is additionally arranged on the sensor, and a breathing hole is formed in the proper position of the filtering cover. The rotation test device for the vertical wheel disc has the advantages of simple structure and easy installation, and avoids the leaked oil from the rotation axis from being thrown on the sensor by the oil thrower wheel; and the breathing hole is formed on the filtering cover, so that the oil mist mixed gas is prevented from being adsorbed on the sensor, and the sensor can truly feels the oil level of an oil saving disc, so as to effectively avoid the false alarm, thereby raising the efficiency of the test device, shortening the test time, and saving the test cost.
Description
Technical field
The utility model relates to a kind of rotation test device, is specifically related to a kind of vertical wheel disc rotation test device of gas-turbine unit turbine dish high speed rotating test.
Background technology
The turbine disk is one of stressed member of gas-turbine unit most critical, and not only rotating speed height, load are big for it, and the working temperature height.For guaranteeing reliable operation, the turbine disk need carry out the low cycle fatigue life test under the warm-up mode on vertical wheel disc rotation test device.In process of the test, form a large amount of high-temperature oil mists and cause danger because of the leakage of oil lack of lubrication or in test cabin, must be in process of the test the leakage of oil situation of monitoring equipment.Existing vertical wheel disc rotation test device is by sensor, the leakage of oil situation that the oily temperature in the monitoring swab case is come the monitoring test device.When a spot of oil leakage went out, oil spill can directly be thrown on the sensor by disc, caused sensor temperature to descend and false alarm; The 2nd, because lubricating system when being the mist of oil mixed gas, has in the space that the mist of oil mixed gas enters swab case, this combination gas is known from experience and is adsorbed on the sensor, causes the sensor false alarm.These two kinds of false alarms all can reduce the service efficiency of equipment, and the process of influence test also can increase testing expenses simultaneously.
Summary of the invention
The purpose of this utility model is the shortcoming that will overcome prior art, provides a kind of simple in structure, and volume is little, and is easy for installation, can effectively avoid the vertical wheel disc rotation test device of equipment oil leakage false alarm.
Vertical wheel disc rotation test device of the present utility model, comprise housing, testpieces and be arranged on housing interior turning axle and swab case, turning axle is provided with propulsion system, disc, be connected with sensor on the swab case, it is characterized in that: have additional a filter mantle on the described sensor, on filter mantle, have air hole.
For further realizing this purpose, described filter mantle is trapezoidal.
The advantage of vertical wheel disc rotation test device of the present utility model is: simple in structure, easily install, can do not got rid of on sensor along the turning axle oil spill by disc, filter mantle is provided with air hole, and the mist of oil mixed gas can not be adsorbed on the sensor yet, and sensor energy sense of reality is to the oil level of swab case, effectively avoid false alarm, improve the efficient of test unit, shortened test period, saved testing expenses.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, swab case, 2, air hole, 3, filter mantle, 4, sensor, 5, disc, 6, turning axle, 7, oil sealing, 8, testpieces, 9, propulsion system, 10, housing.
Embodiment
Vertical wheel disc rotation test device of the present utility model is made up of housing 10, testpieces 8 and the turning axle 6 and swab case 1, the sensors 4 that are arranged in the housing 10.The oil sealing 7 that turning axle 6 is provided with propulsion system 9, the upper end is provided with is connected with housing 10, the lower end is provided with disc 5, and output terminal is connected with testpieces 8.Sensor 4 is fixed on the swab case 1, is connected with a filter mantle 3 on sensor 4, has the air hole 2 of 5 mm dias on the filter mantle 3.
During test, the upper end of turning axle 6 is connected with propulsion system 9, and the lower end is connected with tested wheel disc testpieces 8, and sensor 4 is connected with the control corresponding alarm.Propulsion system 9 driven rotary axles 6 and disc thereon 5,8 rotations of wheel disc testpieces, as oil when oil sealing 7 spills, oil spill slides into for 6 times on the disc 5 along turning axle, disc 5 gets rid of oil spill to filter mantle 3, flow to again in the swab case 1, oil level in the swab case 1 is elevated to when setting oil level, and sensor 4 just can send the oil leakage alarm signal.If lubricating system is the mist of oil mixed gas, oil spill mist mixed gas is subjected to filter mantle 3 and stops, can not touch sensor 4, false alarm can not take place.
Claims (2)
