Mounting apparatus for vibration-measuring sensor

Abstract

The invention discloses a mounting device of vibration sensor, which is a cube. Wherein, the left plane of cube is embedded with a strong magnetic steel whose plane and the left plane form a surface adhered on the tested surface; the lower plane has be cut into the first plane; the angle alpha between the first plane and the left plane and the angle between the tested surface and the vertical surface relative to tested surface are complementary angles to each other; the right plane has the second plane; the angle beta between the second and upper planes and the angle between the upper plane and the vertical surface are complementary angles to each other; the upper plane, front plane, back plane, first plane and the second plane have screw holes. The invention has simple structure, lower weight, which can support the mounting of vibration testing points of variable diesel engine frames. The invention has high efficiency, which can reduce the labor force, improve the safety of workers and the data accuracy.

Description

technical field [0001] The invention relates to the measurement field, in particular to a vibration measuring sensor installation device used in the vibration measurement field of a diesel engine. Background technique [0002] Since the vibration generated by the operation of marine diesel engines is much larger than the vibration generated by ordinary mechanical equipment, when the diesel engine is delivered, it is necessary to provide the owner with an assessment of the vibration intensity level of the diesel engine in accordance with the national standard (GB / T6075.6-2002 idt ISO 10816-6:1995) reports within the specified area. [0003] When measuring the vibration of the diesel engine, in order to correctly evaluate the vibration intensity level of the diesel engine frame, the correct installation of the vibration sensor and the correct selection of the measuring point are crucial factors when measuring the vibration of the diesel engine frame, otherwise it will cause er...

AI Technical Summary

Problems solved by technology

Each selected measuring point needs to be measured in the three coordinate directions of X, Y, and Z, such as point A in the figure, to measure the vibration of point A, it is difficult to install the sensor in the three directions of point A , then use the values ​​of the Z-axis, Y'-axis, and X'-axis measured at point A, A', and A" to approximate the values ​​of the X-axis, Y-axis, and Z-axis at point A, thus giving The accuracy of vibration measurement has a great influence

[0004] like image 3 As shown in the schematic diagram of the structure of the in-line multi-cylinder diesel engine, it is very difficult to measure the vibration in the X-axis direction of the left end 27 and the right end 28 of the machine middle part 25 of the frame base 21, and it is necessary to find a similar position to replace it. It is equally difficult to install sensors on the output end 24 of the top 23 and the left end 27 and right end 28 of the free end 26 of the machine, and it is also necessary to find a similar position to replace; Figure 4 The output end 24 of frame top 23 in the schematic diagram of shown V type multi-cylinder diesel engine, the left end 27 of the machine middle part 25 and the free end 26 of machine and the right end 28 installation sensor are equally difficult, and the engine of V type multi-cylinder diesel engine The planes of the top 23 of the rack and the left end 27 and right end 28 of the rack base 21 have angled slopes with the corresponding vertical planes, so it is more difficult to correctly reflect the accuracy of the vibration data in the three directions measured at this point

In addition, there are many, complex, small space and high temperature on the piping system on the diesel engine, so the actual operation of vibration measurement is complicated, labor-intensive, long working cycle, and personal safety is poor; Vibration data accuracy also has a big impact
