Possible Problems With Hydraulic Lifts After Installation

  Possible problems with hydraulic lifts after installation

  In many cases, factories, floors, terminals and other places after the installation of lifting platform, there will be some adverse reactions, hydraulic lift there will be some of the problems, the following Xiaobian summary of the lifting platform often some problems, and how to solve and prevent these problems Have made some statements.

  A part of the casting, processing and other defects, it is difficult to find in the assembly and commissioning, due to the loosening of the mechanical parts, the vibration and the heat of the machine, the sealing surface of the machine and the pipe joints, etc., However, due to the operation of the vibration, the impact of this defect is exposed, the performance of leakage (infiltration) oil (water). Therefore, the run-in period prone to leakage phenomenon.

  Second, poor lubrication, due to the new assembly of the parts with a small gap, and because of assembly and other reasons, hydraulic lift it is difficult to ensure uniformity with the gap, lubricating oil (grease) is not easy to form a uniform surface of the oil film to prevent wear. Thereby reducing the lubrication efficiency, resulting in early wear and tear of the machine. Serious will cause precision with the friction surface scratches or occlusal phenomenon, leading to the occurrence of failure.

  Third, the occurrence of loose, new parts of the assembly, there are geometric shapes and with the size of the deviation, in the initial use, due to shock, vibration and other alternating load, as well as heat, deformation and other factors, coupled with wear too fast And other reasons, easy to make the original tightening parts of the loose.

  Fourth, the wear speed, due to the new machine parts processing, assembly and adjustment and other factors, the friction surface rough, hydraulic lift with surface contact area is small, the surface pressure situation is uneven. During the operation of the machine, the parts of the surface of the concave and convex parts of the friction with each other, grinding down the metal debris, but also as abrasive, continue to participate in friction, more speed parts with the surface wear. Therefore, the run-in period is likely to cause parts (especially with the surface) wear, wear speed. At this time, if the overload operation, it may lead to damage to parts, resulting in early failure.

  Fifth, the operation errors, due to the structure of the machine, the performance of the understanding is not enough (especially the new operator), hydraulic lift  easy to cause malfunction due to operational errors, and even cause mechanical accidents
