Maintenance of the other valve according to the manufacturer's recommendations;-Report the findings found.Check the door 5 yearThe audit should be done in a minimum period of 5 years is as follows:-15% of opened and closed the next high pressure conditions is not balanced (e.g. under the flow) through an emergency diesel power backup;-Open and close the door under the condition of high-voltage unbalanced (for example water bulkheads are installed) via the diesel emergency power backup; The specific checks should be done together with the dam safety identification program for seven years or 10 years. At that time, the door has to be operated more and experiment with 15% of the traffic that may not be necessary. However the need to ensure that the observations and data records requirements (refer to the monitor the underlying conditions), and have at least one of the doors can be operated using diesel power supply emergency.Dam safety inspection 7 years or 10 years should be included for both the hydraulic structures essential to power production, all the door structure listed in section 6.1. Government Decree No. 72 required minimum overall control after 10 years of operation of the door, maintenance and testing the reservoir capacity is 10 million m3 or more.6.7.6 The required routine maintenance, emergency Diesel generators The tasks of maintenance and frequency of maintenance of the emergency diesel generator side based on the documentation for operation and maintenance of the generator supplier. But must reach a minimum of the following:-Walking test in common;-Check the engine oil and the level of cooling;-Check the oil level;-Check the fan wire stress;-Check the flexible tube to the connections loose or damaged;-Check the battery connections for corrosion phenomena and check the electrodes of batteries;-Check the dust and oil deposits, oil leaks and fuel leaks;-Check and clean the coils;-Check all protected systems by assuming an incident;-Check all the holes of the mounting of batteries;-Squeeze the electric sockets and the sockets for waste pipes;-Changed oil and filters;-Start diesel engine and check gauge and odometer work properly;-To operate the load in four hours.6.7.7 condition monitoring and condition-based maintenance Reviews the condition of equipment and maintenance according to the condition is a form of advanced maintenance, prevent and predict in advance. Maintenance needs are defined based on the condition of the property. Physical properties or trends will be monitored on a periodic basis or for the phenomena such as flutter, particle residue oil, abrasion. Maintenance under conditions as a replacement for the defective maintenance the device does not work, and maintenance over time works by recording the time and odometer. Examples of maintenance programs technician and maintenance conditions according to the conditions described in the following section. Electric motor testing and recording data. The following data should be recorded in all experiments the motor power:-Time;-The opening of the door;-Electric current and voltage motor, as well as the effect that power the engine used;-Pressure hydraulic system for the structural system of the hydraulic doors feedback;-The insulation test and vibration of the engine. All the experimental data should be analyzed by the staff of an appropriate level and are compared with changes in operating the equipment. The results should be made in the appropriate report and the necessary maintenance work to repair should be carried out. In addition, the laboratory for electrical insulation and vibration of the motor should also be done.Check and record data about the operation of doors, valves and lifting equipment Essential in all the time to take notes and observe the operation of the latches get water and lifting equipment by qualified specialists and the appropriate experience. Along with reviews of time opening and closing valves, should observe the watertight and the characteristic fulcrum, vibration of the door, a sound or a sign of a problem.Check the external coating system The lifespan of the hydraulic doors, partitions and other auxiliary lifting equipment will be extended considerably if the coating system is monitored and maintained in good condition. Overall the coating systems usually have a lifespan of about 20 to 40 years, depending on the coating technology and the quality of the paint system. In addition, the longevity will depend quite big on the environmental factors and can see where the Bao Lam project long-1 varnish coating system is greatly reduced due to corrosion problems by sand. Regularly repair coating system should be required to prevent corrosion affecting the structural integrity of the door.Renew or replace The last phase of the lifespan should be the time to consider replacing or refreshing the main parts. Typically the refresh upgrades will include the door remove the glow discharge doors, sand and paint again, replace the watertight system, repair or replace the rollers stop and/or silver lining of roller doors and repairs to the inner steel section of the door. Repair or replace the components
