Most production personnel give the impression that the maintenance department is mainly to repair the faults that have occurred. Unfortunately, this is not the case. The most important part of the maintenance department's responsibilities is to perform routine scheduled maintenance, also known as preventive maintenance. This articleZhongyou Heavy IndustryBring preventive maintenance measures and hydraulic report content of hydraulic system.
Preventive maintenance of 1. hydraulic systems mainly involves:
1) Regular maintenance of equipment;
2) Check whether the operation is correct;
3) Identify potential failures and immediately correct or correct them.
As an often overlooked side benefit, Planned Maintenance trains maintenance technicians in the proper operation and layout of the plant for which they are responsible. If a planned preventive maintenance plan is implemented, most of the common problems listed in the introduction section can be eliminated.
Among the problems encountered in the hydraulic system, more than 50% of the problems are related to hydraulic oil. This is why it is very important to sample and test the hydraulic oil regularly. Today, portable hydraulic oil test kits are available. This facilitates basic testing at the site itself. Tests that may be performed include tests such as determining viscosity, water content, and particulate contamination.
It is essential to train maintenance personnel to perform maintenance activities effectively. The technician should also be able to identify early symptoms of potential hydraulic problems. For example, a noisy pump may be due to cavitation caused by a clogged inlet filter. This may also be due to loose inlet fittings causing air to enter the pump. If the cavitation is caused by air leakage in the pump, the oil in the tank tends to be covered by foam. When air is entrained in the oil, it causes a spongy motion of the hydraulic actuator. Actuator sluggishness may also be due to the high viscosity of the fluid.
2. hydraulic report content:
Good hydraulic reporting and recording system, these reports should include the following:
1) The types of symptoms encountered and how they were detected and the corresponding date;
2) A description of the repair that you did. This should include replacement of parts, downtime and dates;
3) Test, add or replace oil;
4) Date record • Date record for cleaning or replacing the filter.
Proper maintenance procedures regarding external oil spills are also important to prevent safety hazards due to oil spills. Once loose bolts and brackets are found, they should be tightened immediately, as they will cause misalignment of the pump and actuator shafts.
