Regular maintenance content of construction machinery
Construction machinery is an indispensable type of mechanical product in the construction process of modern engineering and construction. However, due to its working High strength, so regular maintenance is required. However, regular maintenance of construction machinery also has levels. Generally, according to the maintenance requirements of various mechanical equipment, after reaching the specified working hours or specified mileage, corresponding maintenance must be carried out. Regular maintenance, and the maintenance levels mainly include the following aspects:
1. First-level maintenance:
The first-level maintenance work is in the example It is carried out on the basis of regular maintenance. The key tasks are lubrication, tightening and inspection of relevant parts and cleaning of the “three filters” (i.e. cleaning of air, oil, fuel filters, etc.). The first-level maintenance is guided by the mechanical team leader and completed by the mechanical operators.
2. Secondary maintenance:
Secondary maintenance work focuses on inspection and adjustment. Specifically, it is necessary to check the working conditions of the engine, clutch, transmission, transmission mechanism, steering and braking mechanism, working equipment, hydraulic system and electrical system and make necessary adjustments to eliminate the faults found and ensure that the mechanical assemblies and parts are functioning properly. Good working performance. Secondary maintenance is completed by mechanical operators assisting maintenance personnel.
3. Three-level maintenance:
The focus is to detect, adjust, eliminate hidden faults and balance the wear and tear of various parts degree. It is necessary to conduct diagnostic inspections and status inspections on parts that affect performance and parts with signs of failure, and then complete necessary replacement, adjustment, and troubleshooting. Level three maintenance requirements are completed by comprehensively skilled maintenance personnel with the help of advanced testing instruments and tools.
In short, in order to ensure the safety of mechanical products and the stability of their performance, Hook Machine Mall reminds everyone to perform regular maintenance on construction machinery.
Construction machinery maintenance skills
1. How to store construction machinery correctly
1. It should be parked in a dry room. If you have to park outdoors, you should choose a flat ground and lay out wooden boards. Cover it with a cover after parking.
2. Before long-term storage, the machinery must be maintained, damaged parts repaired, and thoroughly cleaned to maintain good technical condition.
3. The arrangement and layout of the parking lot should ensure that the entry and exit of any machine is not affected by other machines.
4. The mechanical fuel control lever should be placed in the idle position, and each joystick should be placed in the neutral position.
II, Storage of engines
1. Drain the cooling water in the engine.
2. Replace the engine oil. New engine oil is usually neutral and will not corrode the metal parts of your engine.
3. Fill the fuel tank with diesel to prevent the fuel tank from rusting. Preservatives should also be added if conditions permit.
4. During the shutdown period, the engine should be started once a month to make the machine travel a short distance so that a new oil film can be established in the lubrication parts of each part to prevent rust. It should be noted that the cooling water should be filled before starting and drained at the end.
Three, Storage of batteries
1. The battery should be removed and placed in a dry and antifreeze place. Keep the surface clean and dry. Do not place conductive objects on the battery. When disassembling the battery, first cut off the negative wire, then cut off the positive wire;When installing, connect the positive wire first and then the negative wire. Because the electrical systems of engineering machinery are all connected to the negative pole, this is to prevent short circuits caused when disassembling and assembling the battery.
2, lead-acid batteryIt should be charged once a month.
Four, Anti-rust treatment
1. Before storage, the size of the peeling area of the anti-rust paint on the outer surface should be considered to determine whether to use touch-up paint or re-paint the entire machine for repair.
2. The working equipment of construction machinery, such as the screed of the paver, the bucket of the loader, the scraper of the grader, the hook of the crane, etc., the metal is exposed The anti-rust method is to apply butter.
