School bus safety precautions
1. Lubricating oil pressure sensing, cold water temperature sensing, and low oil pressure alarm are very important. All those who fail should be replaced immediately to ensure that these parts work properly. Failure to do so can cause cracking of the crankshaft due to lack of oil or overheating of the cylinder head due to lack of water.
2. When replacing the oil filter in the maintenance process, the new oil filter should be filled with lubricant and then installed, and after the installation is completed, the engine must be started and allowed to idle, and then get off carefully. Observe whether the filter has leakage phenomenon, if any, it must be eliminated in time, otherwise it will lead to lack of oil and burn out the crankshaft, bearing and other auxiliary components.
3. Each time the engine is started, it must be idling for 3-5 minutes. After all kinds of meters work properly, they can start running. Do not allow the cold car to suddenly increase the throttle, otherwise it will damage a variety of instruments and their corresponding parts, accelerate the wear of the engine moving parts and damage the turbocharger, thereby shortening the life of the engine.
4. It is not allowed to stop and stop suddenly under high-speed, high-load operation, and stop after 3-5 minutes of idle operation. Doing so can damage the supercharger and other moving parts, thereby shortening the life of the engine.
5, should always check the air intake pipe for air leakage, air filter is blocked, if the above phenomenon must be maintained in time, otherwise it will damage the turbocharger and lead pull cylinder failure; the same time the engine power will drop, the vehicle only Can drive at a lower speed and should be repaired in time.
6. Start with a gear when using the engine, otherwise the engine will stall.
7. When it is found that the engine is not working properly, it should be dealt with promptly.
8. When the engine is running, it is strictly prohibited to close to the rotating parts. It is forbidden to directly touch the high temperature parts of the engine (such as the exhaust pipe and the supercharger, etc.); Do not open the radiator cover immediately after shutdown to avoid burns.
9. When the new aircraft is operated within 1500-5000 km/three months, it is necessary to go to the engine service station to carry out the maintenance in time. Otherwise, the free maintenance of the engine will not be implemented.
10. The antifreeze must be used for the cooling system. Otherwise, free maintenance will not be implemented.
11. Some parts of various engines are the same or similar in appearance, such as injectors, diesel filters, etc. Do not replace with other types of parts.
12. Do not flush the engine with water or any cleaning fluid.
13. Put the fuel pre-filter water in accordance with regulations, replace the pre-filter core assembly and the fine filter core assembly.
14. Before removing the battery and disconnecting the battery main switch, make sure the ignition switch is off.
15. It is forbidden to replace the exhaust brake butterfly valve.
16. Lift and transport according to the precautions outside the packing box. The environment where the engine is stored should be ventilated, dry, clean and free from corrosive substances. The effective sealing period of the engine is indicated on the engine packing box.
17. The engine's nameplate contains the basic information of the engine including: calibration power, calibration speed, serial number, production date, and execution standards.
18. The engine model and factory number are printed on the platform in the middle of the lower edge of the cylinder block.
19. Safety warnings include warnings to the user, crankshaft steering, rotation hazards, and high temperature hazards. They are attached to the engine's cylinder head cover, flywheel housing, and cylinder head cover on the side of the exhaust pipe.
20. The following random documents (instructions for use, random parts list, random work list, certificate of conformity, packing list) shall be accompanied by the following random documents in the packing box.
CNC turning is a subtractive manufacturing process in which pieces of material are rotated as a machine tool is fed to the piece, removing material to create a finished piece. It is primarily used to manufacture parts that are cylindrical in nature. We supply custom cnc turning service and CNC turning parts manufacturing
What is CNC TURNING?
Items processed by a lathe will be cylindrical and must be on-centre. Turned parts can range from simple rings to complex curved components. CNC turning is the most efficient way to mass-produce these kinds of parts.
Various cutting tools can be installed within the lathe tooling head to perform different cutting operations sequentially, to produce parts in a one-pass process. Straight cuts, tapers and contours can all be created by varying the angle and depth of the cut.
RongNa CNC Turning system is capable of cutting and holding different types of materials with complete accuracy and efficiency. CNC Turning to manufacture anything from furniture to garden tools to intricate machines and parts for cars and trucks etc.
We are professional CNC Turning Service company and custom CNC Turning Parts manufacturers in China, Our CNC Turning Center help with all kinds of projects and makes cuts of any work piece by changing the angle, the material and the type of cutting tool being used.
