The monitoring part of the equipment detection point is the transmission assembly

 

Combining equipment for point inspection and regular repair, carry out simple diagnosis of main production equipment, equipment on-line monitoring and management of key equipment status maintenance, tendency to manage fault degradation curve drawing of mine crushing equipment status management, comprehensive diagnosis of rotating equipment faults, fault diagnosis of cone crushers, Predict the failure cycle of mining equipment, analyze failure modes, and grasp the probability of failure. Early detection of potential equipment failures, making maintenance decisions, and realizing predictive maintenance of equipment. In recent years, the failure rate has increased, and common failures and sudden failures have increased year by year with the growth of service life. The overhaul is difficult, the overhaul cost is high, and the equipment operation performance is declining year by year. Analysis of the current situation of the moving cone bevel gear cone crusher The type cone crusher is the main production equipment of Lingxiang Iron Mine. Failure mode: The horizontal shaft sleeve is glued, the transmission and the large and small bevel gears are worn and the teeth are broken, the gap between the large copper sleeve of the main shaft is increased, the spherical bush is strained, and the internal failure of the motor. Cone crusher fault diagnosis model analysis fault diagnosis program must be type cone crusher fault diagnosis program is established as shown in the figure, the establishment of the diagnosis part of the fault diagnosis steps, take the cone crusher as an example for diagnosis. The equipment detection point is shown in the figure. The monitoring part is the transmission assembly, and the measurement parameter is the vibration speed. Equipment online monitoring, diagnosis and analysis year and month. The results of the analysis of the cone crusher online monitoring data are listed in the table. The equipment failure fluctuation situation and law, the four monitored data all fluctuate, and the water pressure fluctuation range is large, indicating that the equipment failure is not Independent existence is the interconnection of the internal structure of the host. The results of the frequency spectrum analysis of the vibration velocity of the measuring points of the three equipment No. The equipment No. three side intestines are shown in the figure as the state of the crusher. The internal failure of the host is a complicated factor.

Therefore, the number of measuring points has been intensively monitored, and the frequency spectrum has been used for precise testing and analysis.

What are the characteristics of the CNC turning process?

What are the characteristics of the CNC turning process? Turning is a method of cutting the workpiece on the lathe by rotating the workpiece relative to the tool. Turning is the most basic and common cutting processing method. Most workpieces with revolving surfaces can be processed by turning methods, such as inner and outer cylindrical surfaces, inner and outer conical surfaces, end surfaces, grooves, threads, and rotary forming surfaces. Common lathes can be divided into horizontal lathes, floor lathes, vertical lathes, turret lathes and profiling lathes, and most of them are horizontal lathes.

The Influence of CNC Turning and Milling Machining on Turning Efficiency

The cutting efficiency of CNC lathes will be affected by human factors, environmental factors and the machine tool itself. Let's talk about the influence of cutting amount and cutting tools on CNC lathe processing among many factors.   Reasonable cutting amount can improve the efficiency of CNC lathe. When the   laser  cutting  speed is increased by 10 times and the feed rate is increased by 20 times, far beyond the traditional cutting forbidden zone, the cutting mechanism has undergone a fundamental change.   The result of CNC turning  and milling combined processing is: the metal removal rate per unit power is increased by 30% to 40%, the cutting force is reduced by 30%, the cutting life of the tool is increased by 70%, and the cutting left on the workpiece is greatly reduced. Heat, cutting vibration almost disappeared; cutting processing has taken an essential leap. According to the current situation of CNC lathes, increase the feed per tooth, improve pr...

Machining and welding process notes for TC4 titanium alloy parts

Common welding methods for titanium and titanium alloys are as follows: Argon arc welding, submerged arc welding, vacuum electron beam welding, etc. Tungsten argon arc welding is used for thicknesses of 3 mm or less, and argon arc welding is done for 3 mm or more. The purity of argon is over 99.99%, and the content of air and water vapor in argon is strictly controlled. Currently, for TC4 titanium alloys, argon arc welding, plasma arc welding are often used for welding, but both methods need to be filled with welding material. Limitations on shield gas, purity and effectiveness increase the oxygen content of the joint, reduce its strength and increase its post-weld deformation. Electron beam welding and laser beam welding are used. The following is a description of precision welding and precautions for TC4 titanium alloy. 1. Weld hole problem Table of Contents 1. Weld hole problem 2, internal quality of welded part 3. Weld depth and its variation 4, j...
