How to control the construction machinery, which consumes a lot of oil, without reducing the working efficiency is a very important problem. After investigation found: the key to save oil is the details, in the actual work to develop a good habit, reduce fuel consumption, improve efficiency is very simple. There are several tips from SINOTENG that you can use for reference based on your own daily construction situation:
First,SINOTENG excavator arm and bucket selection techniques
Many new users will think that the larger the excavator bucket work faster, the higher the efficiency, in fact, this is a misunderstanding of understanding. Bucket capacity is determined according to the bucket stack capacity. However, due to different materials, the loading capacity in actual work also varies, such as wet clay, which may reach the bucket digging coefficient as high as 100-110%, but for some stones, the bucket capacity coefficient is relatively low.
The length of the excavator arm determines the digging force of the excavator. In the actual work of the operator, SINOTENG excavator is equipped with a short arm, which is suitable to be equipped with a larger bucket, so that the digging force is larger. With a longer arm, the mining range can be controlled more.
Therefore SINOTENG excavator users should according to the working condition of choosing appropriate bucket, can obviously fuel efficiency. In addition to bucket, bucket tooth selection also has a lot of knowledge, penetration bucket tooth is more wear-resistant, in practical work can improve efficiency, save fuel.
Second. SINOTENG excavators with fuel-saving techniques
So what height platform is appropriate? The height of the platform is determined by the length of the bucket. The distance between the pins is the ideal height. In order to save fuel, in addition to the control of working height and distance, there is also the cycle time of digging. Each bucket of digging should be controlled within 24 seconds to 28 seconds, and 4-6 buckets should be filled with a truck within 2 minutes.
And the bucket filling coefficient is controlled at 80-110%, each bucket as full as possible. In the process of excavation, the number of rotation should be reduced as far as possible, and the rotation Angle should be reduced to less than 60 degrees. Although the rotation range of the excavator can be controlled by itself, the useless rotation range will only consume fuel oil, but it has no effect on the improvement of the work efficiency.
Three, SINOTENG excavator positioning fuel-saving skills
The correct digging method of the operator should be from right to left, because the excavator cab is located on the left side, digging from right to left, the big arm is on the right side, the line of sight will be better, which is conducive to the excavation.
Four, Fuel saving skills for truck and SINOTENG excavators
When excavator excavates and loads, the placement of truck and excavator is also a knowledge. There are two ideal loading methods. The first is over the side plate. While the excavator was digging, the two trucks were loaded upside down and over the side of the truck. This method has a full excavation range and a small swing Angle. The second way is "passing through." When a truck is loaded, have a truck come to the top immediately. This method is short, suitable for the number of trucks is relatively small, can immediately load the car, the swing amplitude is a little bit large.
Five. SINOTENG wheel loader fuel saving skills
The loader can be loaded by a method called "v-loading method". The loader is facing the material pile, and the truck and the loader drive at a 45° Angle. When loading, the loader lifts the bucket, which can put pressure on the front wheel, so that the friction force is increased and the driving force is stronger. After the bucket is filled, the loader backs up 1.5 laps of the tire to form a v-shaped loading.
In addition to SINOTENG excavator users, also can undertake fuel-efficient in some detail, especially summarizes the points:
1. Prevent engine idling. Even at idling, there is oil circulating in the hydraulic pump and consuming fuel. If one hour out of 10 hours a day is idling, about 20 litres of fuel per month and about 230 litres per year can be saved if idling can be prevented. That's nearly 2,000 yuan.
2. Prevent overload loss of pressure. When the excavation of sand or rock load is too heavy, even pull the lever operation machinery also no action, and fell into the state of pressure loss. If 6 minutes of operating time in 10 hours per day is in the state of loss of pressure, then, if the loss of pressure can be prevented, about 70 liters of diesel oil can be saved every month, and about 840 liters of diesel oil can be saved every year, which costs nearly 5,000 yuan.
3, reduce the engine speed. Although reducing engine speed will affect the amount of operation, it can greatly reduce fuel consumption and improve fuel efficiency. That is, of course, if it doesn't make the job less efficient, which could turn off employers and cost them the job.
4. Reduce the rotation Angle. Reducing the rotation Angle when loading into the dump truck can shorten the operation cycle and increase the amount of operation per unit time, thus improving the fuel consumption efficiency. This is also an effective way to save fuel.
5. Reduce the engine speed when walking. The faster the engine revs, the more fuel it consumes while walking. Fuel efficiency can be improved by reducing the engine speed during running.
6. Implement high level excavation. In the excavation site, the higher part is firstly excavated and then the lower part is excavated. Compared with the lower part, the cycle time of high mining can be shortened by about 12% and the burn-up efficiency can be improved by about 8%.
At the same time, SINOTENG excavator operator's operation is the key to fuel economy, reduce mistakes sometimes can be fuel efficient, effectively save fuel need operator to kung fu spent on each detail, may spend bit of idea on an action can make work better.
