Single leg Standing Desk is one of our sales products. This single leg has Electric Standing Desk and Pneumatic Standing Desk. This product is very popular at present. We also developed a single leg electric desk under the customer demand. The single leg pneumatic desk has always been very popular because of its high cost performance and small size. It is suitable for adults and children. A small tea table and a temporary operating table are placed beside the sofa in the living room for work, leisure and dining. Sit Stand Desk has the design of universal wheel, which can be moved and placed beside the bed at any time. Users can study and work directly on the bed, and it can be used with the disabled bed.
At the production site, when a failure occurs during the operation of machinery and equipment, the mechanics are required to quickly determine the failure and take corresponding measures. They can be judged directly by asking, looking, smelling, listening, and touching. The question is to ask the operator when the fault has occurred. Find out what happened after the sudden, gradual, or after the repair, and the previous treatment. Operators are familiar with the characteristics of their own operation of the machine, and when the machine fails to see and hear, provide first-hand information on the analysis of failures, so it is very helpful to analyze, determine the cause of the failure; see is to observe the parts where the failure occurred Location and type of workpieces and conditions of the surrounding environment at the time; sniffing is to use the olfactory organs to smell the smell of the scene to determine, for example: the temperature of the motor is too high or the insulation of the motor windings burn out the insulation, paint odor; Distinguish the abnormal sound of the various transmission machinery and the parts that are produced; the touch is whether the temperature or vibration of the hand touch device is normal. In this way, judgments can be made quickly by asking, looking, smelling, and listening to the captured information.
When the above basic method is used to determine the location of the fault or the cause of the fault, consideration should be given to the method of segment isolation or step-by-step inspection. For example, if the cutter of the paper cutter or the paper press brake does not operate normally and the pressure is insufficient, check the oil pressure first. Check the other aspects normally. If it is not normal, check the oil level, the oil cylinder or the tubing head connector; then check if the solenoid valve is Normal, check the lower level, otherwise check the contactor and so on. Of course, for the inspection of this system, it is necessary to find out the principle of action and the sequence of actions, and then trace the faults one by one. The causes of the failures of offset presses in offset printing are relatively complex. There are many factors such as equipment, materials, environmental factors, and the operator's skill level. In this case, the “step-by-step method†is used to check and troubleshoot the defects. The effect is better. . For example, there are ghosting problems with offset printed products. The following stepwise step-by-step checks are generally used to find out the reasons: 1 Check whether the quality of the paper meets the quality standards, such as the presence or absence of flounces or curls; 2 Check pressure Whether the force of the printing cylinder gripper is normal, because the force is insufficient or inconsistent, the paper will be displaced in the embossing; 3 whether the liner is suitable, because the liner status will affect the sliding between the rollers; 4 The shaft heads, bushings, and wall plate holes of the plate and blanket cylinders produced large gaps due to wear, resulting in large vibrations during operation. Or the wear of the roller gear or the bearing or the gap between the three rollers is not equal; 5 The axial displacement of the plate cylinder or blanket cylinder occurs; 6 The overall accuracy of the offset press is not good.
In short, through the above-mentioned step-by-step inspection, it is generally possible to achieve the purpose of identifying and troubleshooting.
It is worth mentioning that, whether it is on-site production and management personnel, machine repair personnel, or machine operators, it is very important to determine the faults in order to familiarize themselves with the common mechanism faults. In printing and packaging machinery, belt drives, gear transmissions, bearings, and other mechanisms are usually set up. It is important to understand these common mechanism fault diagnosis methods to prevent the extension of machine failures and reduce losses.
The following examples illustrate some common institutional failure phenomena for reference.
First, gear transmission: When the gear meshes in the transmission, it will produce squeaky squeaks, and will increase with the increase of the rotation speed. Generally, the meshing clearance is too small; if the transmission produces a sound, and the sound decreases with the increase of the load, It is the gear meshing gap in the transmission that is too large; if the hum sound is intermittent, it is usually a tight half-circle loose half-circle, which is mostly due to the poor manufacturing accuracy of the gear or the bending deformation of one of the shafts. If a percussive sound is generated in the transmission, the center distance between the two axes is generally large or the gear tooth is thin and narrow.
Second, the belt drive: In the same group, the length of the belt or different groove depth, the pulley shaft bending will produce greater vibration, vibration may also be the source of those sophisticated equipment. If it is adjusted too loosely, a strange sound will be generated at the start, and the rotation will be slow, the driving wheel will be heated, the adjustment will be too tight, it will make a buzzing noise and cause the belt and the belt pulley to be in a tendency to damage the belt.
Third, the bearings, rolling bearings are too tight: with the shaft or bearing holes with large surplus, shaft and hole processing accuracy and poor lubrication, high-speed will produce screams and heat, smoke, too loose to adjust the noise Large, it will also damage the shaft and gear on the bearing. After a certain period of time, the bearings will wear out, the accuracy will drop, and the balls and raceways will be damaged. Once this type of failure occurs, it will inevitably have a bad influence on the normal operation of the machine. Therefore, in machinery and equipment, when bearing assembly components fail and affect product quality, we must not neglect the inspection and treatment of bearing quality.
