Cautions for Operation of Vacuum Stone lifter in Special Environment

Vacuum stone lifters can be used even in very special environments. However, special maintenance should be done for stone lifters in special environments, and some matters should be paid attention to when using them.           
 1.  Use in low temperature environment: When vacuum lifter is used in the environment below 5 degrees, air drying should be installed to prevent condensation and freezing of water in compressed air.            

 2.  Shock and vibration: The impact on vacuum components should be 150 m/s. Below,  the vibration should be 40m/s. Following. If this value is exceeded, it will cause erroneous action. 

 3. When wiring pressure sensors and other conductors, they should be far away from high-voltage power supply machines, high-voltage wires and power lines with greater interference. Otherwise, it will cause misoperation or malfunction. The export of vacuum lifter has promoted the upgrading of China's machinery industry-related products.           
 In  this situation, enterprises pay more attention to scientific and technological innovation, research and development of high-end equipment manufacturing industry, improve the industrial level of machinery industry. Many powerless vacuum stone lifter enterprises have intensified technological transformation and upgraded their products to achieve high growth in efficiency and production and marketing.           
 What should we pay attention to when using vacuum stone lifter? Let's get to know it. Please don't use it in the environment with corrosive gases, chemicals, seawater, water vapor or with the above substances. When there is direct sunlight, please use protective shield to block the sunlight. When there is a heat source around, please cut off the radiation heat. When installing solenoid valve on the control panel, take heat dissipation measures to meet the temperature range required by specifications. Where spark splashes occur during welding, Please add protective shield. Sparks can burn out the plastic parts of solenoid valves and easily cause fire. When water droplets drop directly on the solenoid valve, it will cause leakage and coil burnout. Please pay attention to  protection, install protective cover for solenoid valve or set it in panel.           
 How to choose vacuum stone suction cup: when applying the formula of vacuum stone suction cup, we must calculate its working environment coefficient and safety factor for large area, heavy suction cup, vibrating suction cup or suction cup  requiring quick handling. In practical application, in order to prevent the dropping of suction and suspension objects, suction and suspension are usually carried out by using multiple suction cups. At this time, attention should be paid to the rational allocation of these suction cups, so that the suction and suspension force action point is as close as possible to the center of gravity of the suction and suspension objects.           
 The bonding degree between vacuum stone lifter and the surface of the adsorbed workpiece directly affects the vacuum pressure in the lifter. If the bonding degree is too bad, the vacuum degree of the lifter is not easy to maintain, and the purpose of adsorbing the workpiece can not be achieved. When using vacuum stone lifter, we always hope that the part of the surface contacted by the  workpiece and the lifter is smooth and sealed, which is conducive to the vacuum lifter firmly grasping the workpiece surface. However, it is only an ideal  state. Usually the surface of the workpiece captured does not have such ideal conditions. The workpiece surface is either porous or rough. These factors directly affect the degree of suction cup and workpiece surface fitting. When the suction cup and the workpiece surface are in poor condition, the leakage phenomenon we often say will occur. There are usually two measures to remedy the leakage system:           
 1.  Use high-performance vacuum generator to make the leaked gas replenished in a short time. The disadvantage of this method is that there is still a large leakage in the system, and the energy consumption is high.            
 2.  Reduce the diameter or diameter of the lifter. The disadvantage of this method is that it can not reach the required vacuum level when the workpiece quality is large.
