Analysis of the reasons why hydraulic presses need regular inspection

by:WORLD     2022-08-27

A hydraulic press is a machine that uses liquid as the working medium to transfer energy to realize various processes. In addition to forging and forming, hydraulic presses can also be used for straightening, pressing, packing, pressing blocks and pressing plates. After the machine has been running for a period of time, it needs to be checked, so that some mistakes can be avoided, and the hydraulic machine is no exception. Today we will talk about why it needs to be checked regularly?



Regular safety inspection is an effective method to reduce the number of hydraulic machine failures and avoid machine damage and personal injury accidents. It is an equipment management system that should be formed by user units. The regular safety inspection of hydraulic presses is mainly based on equipment managers and maintenance personnel of user units, supplemented by operators. Check at least once a year.


The main components, hydraulic and pneumatic lubrication system, electrical equipment, safety protection devices, etc. should be comprehensively inspected according to the characteristics of the hydraulic press. Targeted special exclusion of possible unsafe factors. Such as: check and calibrate indicating devices such as pressure gauges, and replace the sealing elements that need to be replaced in the hydraulic part.


Check the overload protection device of the hydraulic and electrical system of the hydraulic press, check the operation control and emergency stop device of the electrical system, restore its original performance, and replace components, such as limit switches, if necessary. Check the connecting wires of the electrical equipment and the grounding protection device to prevent the joints from loosening, the components being loosened, the insulation being damaged and aging.



Check the integrity of safety guards, such as guardrails, guards, etc. The problems found in the regular safety inspection of the hydraulic press must be repaired in time according to the instructions to ensure the safety of the hydraulic press.


Pay attention to life safety during inspection, and check items must be clarified during operation and after shutdown; make a record after each inspection is completed, whether it is in good condition, abnormal, and whether there is maintenance.
