  Lift ElevatorAt the beginning of the use, may be because of the machine do not understand, which will cause failure due to improper operation, serious may also cause mechanical accidents.

So you know the early days of use, what are our common problems? In order to let you all can be in the elevator elevator early use smooth, below for everybody simple analysis, hope to help everyone.

Problem one: Loose parts. Lifting the new processing assembly parts, there is a combination of shape and the size of the deviation, the initial use, due to impact, vibration and other alternating load, as well as heating, deformation and other factors, coupled with wear too fast and so on, easy to make the original fastening parts loose.

Problem two: Parts wear fast. Due to the new machine parts processing, assembly and adjustment and other factors, its friction surface roughness, with the surface contact area is small, the surface pressure condition is uneven, the machine in the running more process, the part surface concave and convex parts of each other inlay friction, grinding down the metal debris, and as abrasive, continue to participate in friction, It also accelerates the wear of parts with surface.

Problem three: leakage occurs. Due to the loosening of the mechanical parts, vibration and the effect of machine heating, lift the cover of the freight elevator and pipe joints, there will be leakage phenomenon, part of casting, processing and other defects, in the assembly debugging difficult to find, but due to the operation of the vibration, impact, this flaw is exposed, performance as leaking oil, Therefore, the running-in period prone to leakage phenomenon.

Problem four: poor lubrication between parts. New assembly parts with small clearance, coupled with assembly and other reasons, it is difficult to ensure the uniformity of the gap, lubricating oil is not easy to form a uniform oil film on the friction surface to organize wear, thereby reducing the lubrication efficiency, resulting in early abnormal wear and tear. When serious, it will cause the friction surface scratching or occlusal phenomenon of the precision match, which causes the malfunction.

Above four kinds of situation is the elevator elevator in the early use of the four major problems, if you are in use when there are other problems, welcome to lock our official website.
