Winter maintenance precautions of the excavatorAs a complex large-scale machinery, excavator will inevitably encounter various faults and problems in operation. It is important for professional operators to master some basic knowledge of excavator maintenance. Today, TDER excavator small class for everyone to share some basic maintenance points.1. The excavator has startup problems or startup difficultiesIt may be caused by a fault in the electrical system, or a low battery charge. It is necessary to check the electrolyte height to ensure that it is on the specified scale line, and maintain the battery regularly to avoid loss of power. Aging batteries should be replaced in time.The starter, engine, or wiring may be faulty and need to be repaired or replaced in time. 2. Working device wear and deformationRegular inspection of commonly used working devices is required to pay attention to whether there is wear and deformation. If serious wear or deformation is found, repair or replace it in time according to the extent of damage. 3. Tracks fall offRegularly check the tightness of the track, as well as the guide wheel, gear ring and other parts. If it is found that the wear is serious, adjust the tightness of the track in time or replace the accessories to prevent the track from falling off during the work. 4. Oil leakage problemIf there is oil leakage in the excavator, first find out the oil leak point and analyze the cause of the oil leak.Oil leakage is divided into internal leakage and external leakage, internal leakage may be caused by aging, wear or damage to the main oil seal, and the oil seal needs to be replaced. When replacing the oil seal, if the piston rod scratch is found, the scratch should be treated before replacing the oil seal.The causes of external leakage are various and need to be analyzed in detail....

             1. Maintenance every 50 working hours (1) Tighten the connecting bolts of the front and rear drive shafts. (2) Check the gearbox oil level. (3) Check the oil level of the brake booster. (4) Check the tire pressure and damage. (5) Grease is injected into the front and rear frame hinge points, drive shafts, auxiliary frame pins, and other bearings. (6) Check the air filter element and replace it if necessary. 2. Maintenance every 100 working hours (1) Clean the dust and materials on the engine cylinder head, torque converter, and oil cooler. (2) Check the battery liquid level and apply a thin layer of butter on the joints. 3. Maintenance every 250 working hours (1) Check the rim fixing bolts. (2) Check the oil level of the front and rear axles. (3) Check the working device, front and rear frame, auxiliary frame, all welded and fixed bolts for cracks and looseness. (4) Replace the engine oil (it can be determined according to the quality of the engine oil). (5) Check the tightness and damage of the engine generator fan belt. (6) Check the braking condition of the adjusting foot brake. (7) Add grease to the fan pulley, tensioner and water pump. (8) Tighten engine cylinder head bolts, check and adjust valve clearance. 4. Maintenance every 500 working hours (1) Fasten the connecting bolts of the front and rear axles and the frame (2) The engine oil and oil filter element must be replaced. (3) Clean and replace the gearbox oil and oil filter. (4) Check and adjust the engine valve clearance. (5) Clean the diesel tank and oil suction filter element. (6) Disassembly and maintenance of motors and generators. 5. Maintenance every 1000 working hours (1) Replace the gearbox oil and oil filter.

             1. blasted the throttle as it startedWhen the loader engine is just started, the body temperature is low, large oil viscosity and poor mobility, and the oil can not flow freely to each lubrication point in a short period of time.If the throttle is bombarded at this time, the engine speed will instantly increase. Although the oil supply and pressure of the oil pump will also increase, the requirements of the quantity of lubricating oil and oil pressure cannot be meet, and the movement side can not establish a good lubricating oil film, causing instant dry friction, resulting in severe wear and tear.Each movement auxiliary lubrication is poor, and the operation resistance will also increase. If the throttle is bombarded, the piston, connecting rod and crankshaft will produce violent impact and accelerate the damage of the parts.In addition, the diesel engine equipped with a turbocharger is easy to damage the oil seal due to bad lubrication, resulting in a turbocharger failure, and reduce the power of the diesel engine.Therefore, the loader shall operate at a steady low speed (about 500~700 r / min) against throttle.2. starts directly without the heating machineDue to the low temperature of the body, large oil viscosity, will make the oil pump insufficient, resulting in a short time of movement without a good lubrication, wear intensified.Large load, there will even pull cylinder, tile and other accidents.In winter, the hydraulic hose is brittle, direct operation is easy to burst, will make a large number of hydraulic oil leakage.Therefore, after the loader is started, idle and test operate until the oil temperature and oil pressure reach normal....
