A reduction of unnecessary loss of power
1 the accurate application and protection of exhaust pipes and mufflers. It includes carbon deposition in the muffler, timely repair of damaged noise reduction panels, no forward installation of the exhaust pipe, no use of self-made fine and too long exhaust pipes.
2 keep the excavator's walking system in good state.
3 to strengthen the protection and maintenance of the brake system of the excavator, especially to prevent the brake "stagnation", that is, the brake friction disc and the brake drum are in contact with the brake. The simple way to judge the "stagnation" of the brake is whether the brake drum is often perm with the hand touch.
When the locomotive of the 4 power steering gear is swerve, the steering wheel will be slightly relaxed after turning the steering wheel to the limit position so that the valve slide valve can return to the neutral position, otherwise the time of the maximum oil pressure in the hydraulic system is too long, which will lead to excessive power consumption of the engine and increase the wear of the engine parts.
Two frugal fuel consumption
1. the lubricating oil should be added to the engine oil bottom and the transmission should not exceed the top line of the oil scale; the grease filling to the wheel wheel will only reach the space of 1/2 to 2/3. If the lubricating oil is overfilled, not only the oil is wasted, but also the running resistance of the coherent part is increased and the engine is increased. Power loss.
2. equitable application of throttle according to different conditions is not only a necessary condition to ensure the normal operation of locomotives, but also an important measure for thrifty energy.
When the excavator engine starts, it should shake the crankshaft number circle first, then start with the medium throttle. If the engine is started with a large throttle, the engine can not start several times, and the fuel is easily "drowned" engine.
When excavators start, they should properly increase the throttle and prevent the engine from stalling. If the engine is restarted, it will be very expensive.
When the excavator accelerates, it should be accelerated but not speeded up. According to the experiment, the vehicle accelerates from the start to the medium speed (30km/h), and the fuel consumption of the rapid acceleration (25s) is about 2 times that of the slow acceleration (40 1 45s).
The speed of the excavator should be economical, so that it is safe and fuel efficient.
When the excavator is maintained and checked, if the shakes should seal the throttle, the injector will not stop injecting oil into the cylinder, too much fuel into the cylinder, not only to waste fuel, but also to cause the next starting hard, while some fuel flow along the cylinder wall flow to the oil bottom, causing the oil to deteriorate easily, and then speed up the wear of the engine parts and decrease the work of the engine. Rate;
When the excavator stops, if the vehicle stops more than 10min, the engine should be extinguished, because the long idle running is very harmful to the engine and waste fuel. Before parking, the "bombardment" is prohibited. The "bombardment" before parking is harmful to the engine.
