First, reduce unnecessary power loss
1. Proper use and maintenance of the exhaust pipe and muffler, including frequent removal of carbon deposits in the muffler, timely repair of damaged sound-absorbing partitions, no forward installation of the exhaust pipe, no use of self-made fine and long exhaust Tubes and so on. It has been determined that if the bore diameter of the exhaust pipe of the 195 diesel engine is reduced by 10mm, the engine power consumption will be 0.75kW.
2. Always maintain a good technical state of the walking system of agricultural vehicles. If the wheel wheel bearing is too tight and the tire pressure is too low, the frictional resistance of the vehicle will increase. According to tests, 30%-40% of the vehicle's output power is consumed to overcome the tire's rolling resistance. Therefore, the tire pressure should always be maintained, driving properly and selecting roads.
3. Strengthen the maintenance of brake systems for agricultural vehicles, in particular to prevent the brakes from “snapping upâ€, that is, when the brake pads are in non-braking condition. A convenient way to determine the "stuck" of the brake is to touch the drum with your hand to see if it is hot.
4. When the tractor with air pump is engaged in stationary work such as pumping, power generation and processing, the belt of the air compressor should be removed. After testing the tractor with a pneumatic brake trailer, the power consumed by its engine-driven air compressor is approximately 1.5 kW at a low pressure of about 1.1 kW at high pressure; under rated operating conditions, the engine drives the accessories (refers to the cooling fan, The power consumed by pumps, generators, air compressors, etc. is approximately 10% of the total power.
5. When the locomotive with power steering device makes a sharp turn, it should be slightly relaxed after the steering wheel is turned to the extreme position, so that the distribution valve spool can return to the neutral position. Otherwise, the maximum hydraulic pressure in the hydraulic system will take too long, resulting in The engine consumes too much power and increases the wear of the components.
6. When the tractor is engaged in transportation and field operations without hydraulically-held agricultural implements, the power of the hydraulic oil pump should be separated by a joystick, which can reduce the power consumption of the engine and at the same time prevent the wear of the hydraulic suspension system components.
7. If the tractor is equipped with a permanent magnet alternator, it is necessary to remove the permanent magnet generator during the daytime operation. This not only can reduce the power consumption of the engine, but also can prevent the damage of the generator bearing and the regulator and prolong the generator. The service life.
8. Installation of farmland irrigation water pumps should avoid "air gun type" that the outlet should be as close as possible to the level of the channel. When the height difference between the irrigation ground and the water source is 10m, if the installed outlet pipe outlet is 1m higher than the channel water level, it will consume 10% more energy (electric power or fuel oil). The solution is to reduce the height of the water pump outlet pipe as much as possible.
Second, save unnecessary fuel consumption
1. Add lubricating oil should be enough. Lubricating the engine oil sump and the transmission should not exceed the upper marking of the oil scale; filling the wheels with only 1/2 to two-thirds of the space can be filled with grease. If the lubricating oil is overfilled, not only the oil is wasted, but also the operating resistance of the relevant parts is increased, and the power loss of the engine is increased.
2. Reasonable use of the throttle according to different conditions, which is both a necessary condition to ensure the normal operation of the locomotive, but also an important measure to save energy. For example: When the engine starts, crank the crankshaft several times before starting with the throttle. If you use a large throttle to start, several times can not start, fuel is easy to "drown" the engine; when the vehicle starts, it should increase the throttle, to prevent the engine flameout, if you restart the engine is very costly; when the vehicle accelerates, it should be accelerated And can't speed up. According to the test, the vehicle accelerates from the start to the moderate speed (30km/h), and the fuel consumption of rapid acceleration (25s) is approximately equal to twice the fuel consumption of the slow acceleration (40-45s); the economic speed should be adopted during driving. This is safe and fuel-efficient. In maintenance and inspection, if the crank should be closed, the fuel injectors will continue to inject fuel into the cylinders. Excessive fuel will enter the cylinders, which will not only waste fuel, but also make it difficult to start the next time. At the same time, part of the fuel flows down the cylinder wall into the oil pan, which can easily cause engine oil to deteriorate, and then accelerate the wear of the engine and reduce the power of the engine. When the vehicle is stopped for more than 10 minutes, the engine should be turned off because of the long idle operation. It is very harmful to the engine and it wastes fuel. Stopping the "throttleboard" before parking to stop the "boom throttle" is not good for the engine.
A key box is a special box for storing keys. It is usually made of cold rolled steel. It is a kind of steel office furniture. The biggest difference between it and the ordinary box is that there are many hooks on the key box for hanging the key. Using a key box to store keys can effectively store and classify keys. So that enterprises can be high quality, efficient management.
