How to Solve the Collision of Stone Vacuum lifter during Operation

 If the number of stone vacuum lifters is not very large and the diameter of lifters is not very large, it is more economical to use jet vacuum generator to produce vacuum. Because the jet vacuum generator itself needs compressed air to produce vacuum, it does not need to assemble other vacuum pipes. If the vacuum consumption is relatively large, such as color picture tube manufacturing enterprises, the use of vacuum pumps is more reasonable. The synthetic fiber hoisting belt of vacuum hanger is made of high strength polyester, polypropylene or polyamide industrial strong filament, which is woven on industrial loom. Compared with the traditional wire rope and chain hanger, synthetic fiber hanger has the following advantages: 1. Protect the hanging objects so that their surfaces are not damaged. 2. High strength, light weight,  easy to carry and prepare for hoisting. 3. Soft and easy to operate. 4. Non-corrosive and non-conductive.           
 Occasionally, squeezing and collision occur during the operation of stone vacuum lifter. What is the reason for this situation? It is because the hanging objects are placed  unstable and the dumping and collision occur. One: Because of improper  placement of suspended objects in Beijing axial flow fan of impact crusher, necessary safety measures have not been taken to prevent the instability of major suspended objects. 2. Poor site management of crane operation. In the operation of commanding or overhauling mobile crane, it is squeezed and collided, that is, as a person, between the operating mechanism of vacuum lifter and the rotary mechanism, by the working stone vacuum lifter. Reasons: one is  the improper position of the command operator; the other is the lack of necessary safety protection measures in the overhaul operation. Vacuum stone lifters are suitable for smooth, flat surfaces. They will quickly grasp and release, these vacuum lifters grasp the vertical surface very well and expand the use of the shape of the lifters, including wedge-shaped vacuum lifters in lifting the load is better, no wedge-shaped vacuum lifters can lift the load. Stone vacuum lifter has different operating rules and regulations in different stone machinery  products, so it can not be treated equally. In the process of assembling machinery, there are still many problems to be noticed and observed, and many key points of work are to abide by the contract together. For example, in the process of using, we must do a good job of cleaning and cleaning parts, cleaning work includes: removing residual casting sand, rust, etc., especially  some important parts, the inner cavity should be coated with anti-rust paint. Oil contamination and rust on parts can be cleaned with diesel oil and kerosene  as washing liquid, and then dried with compressed air. The assembly of wheels should be in the same plane as the center line of the axle. Parallel to each  other. When the stone vacuum lifter is clear, it is necessary to check whether the raceway and rolling body are rusted and whether the rotation is flexible. When assembling bearings, a layer of lubricating oil should be coated on the surface of the fittings. When assembling, if the pressure difference is too large, the assembly should be stopped for inspection. When assembling the bearing, the non-model end should be inward, shoulder-side direction, the magnitude, direction and position of the force applied when assembling the bearing should be appropriate. The rolling body of the raceway should not be stressed. It should be struck symmetrically and evenly, and not be slammed so as to ensure that the end face is perpendicular to the shaft. Prevent installation tilt.
