The larger the angle of the elbow, the smoother the better, and should not exceed 3. Heat insulation measures shall be taken for exhaust pipe. When installing the external exhaust pipe, the exhaust back pressure should be less than 2.5kpa |
|
| 4 | Auxiliary support | Auxiliary support shall be set on the pipeline less than 1.2m away from the turbine outlet. It is not allowed to install the muffler into the exhaust pipe without auxiliary support, as shown in Fig. 2 During the installation of 8170 dual supercharged diesel engine, the two exhaust pipes can be combined into one exhaust pipe. The specific requirements and layout are shown in Fig. 3. |
|
| 5 | Improve air circulation | The engine room shall be well ventilated, and ventilation devices shall be installed. | |
| 6 | Exhaust expansion joint | Under the cold state, the expansion joint shall not be compressed and the elongation limit shall be SMM. At the same time, the expansion joint shall be kept vertical without bending and torsion, as shown in Fig. 4 | |
| Seawater system | 1 | Seawater pump | The inlet of seawater pump must be lower than sea water level. The thickness of the base for installing the external seawater pump is required to be no less than 12mm, and the support should be firm. If necessary, the reinforcement can be added to reduce the vibration. For the measurement of belt tension, the straight distance between the center points of the span of the tangent points of the two pulleys should be less than 1.6% of the center distance. |
| 2 | Intake | The inlet pipe must be equipped with seawater filter, and the filter hole is φ 2 - φ 4mm. | |
| 3 | Inner diameter of inlet pipe of seawater pump: ≥ medium 71mm. | ||
| 4 | Outlet | Inner diameter of outlet pipe of seawater pump: ≥ φ 51mm | |
| Starting system | 1 | Electric starting | When the battery connecting line is less than 2m, the cross-sectional area shall be no less than 70mm: (recommended) When 2m < battery connecting line ≤ 5m, the wire cross-sectional area shall be ≥ 120mm2 The negative wire of starter is connected with the negative pole of battery, and grounding is not allowed. |
| 2 | Air starting | The gas pipe connected to the air motor shall be GI pipe with the length of less than 2m, pressure resistance of 6Mpa, and the working pressure of the air motor shall be 0.7-09mpa. Before starting, the lubricating oil in the oil mist cup shall not be less than 1 / 3 of its volume, and the liquid level shall not exceed the lower end of the filling plug. It is recommended to use the lubricating oil in the oil mist cup within 3-4 months. Type of lubricating oil: No.22 turbine oil or No.10 mechanical oil shall be chose when the ambient temperature is higher than - 10C; No.8 jet lubricating oil shall be chose when the ambient temperature is lower than - i0c. Sandblasting, pickling and phosphating are required for the connecting pipes of air motor. When the pipeline system is installed, the oil mist eliminator and air filter must be installed behind the pressure reducing valve, because the maximum operating pressure of the two is 1MPa, so as to avoid danger. |
|
| 3 | Charging generator | The B + and b-electrodes of the generator are connected to the positive and negative electrodes of the battery respectively. Connect D + to D + terminal on yuanhangbao harness. | |
| 4 | Battery | Battery capacity x quantity: 200ahx2. | |
| lubrication system | 1 | Oil quality | Weichai aviation protection series special engine oil should be used to ensure the legitimate rights and interests of customers. (Note: according to the difference of special area and ambient temperature, please select the oil grade according to the actual situation. It is allowed to replace the low quality oil with high quality oil. Different quality oils are not allowed to be mixed) |
| 2 | Oil quantity | 6 cylinder: 55L; 8 cylinder: 77l. (the actual oil filling amount is subject to the oil dipstick line) | |
| 3 | Oil gas separator | It is suggested that the outlet of the pipeline should be connected to the outside of the engine room. When the customer connects the extension pipe of the oil gas separator, it is necessary to ensure that the crankcase is connected with the atmosphere. The end of the extension pipe should be provided with a protective cover to prevent foreign matters from entering the oil-gas separator. The extension pipe should be far away from the exhaust pipe and other high-temperature parts to avoid fire and other potential safety hazards. | |
| Fresh water system | 1 | Coolant | It is suggested that Weichai special antifreeze should be used. The freezing point of the antifreeze should be 5C lower than the local minimum temperature. If there is no special antifreeze solution, clean water with low hardness can be treated by adding water treatment agent to prevent corrosion and pitting corrosion of cooling system and diesel engine water chamber. (it is strictly forbidden to use sea water, river water, saline water, alkali water, industrial water, etc., and when the temperature is lower than 0C without antifreeze, the cooling water in the machine shall be drained completely.) |
| Fuel system | 1 | Diesel oil | In summer, No.0 light diesel is gb19147; in winter: - 10 light diesel is gb19147. (Note: for the difference of special regions and seasons, please select the diesel brand according to the actual situation) |
| 2 | Diesel oil return line | The fuel return pipe of diesel engine must be connected to the top of daily fuel tank, and the recommended limit of return oil height is 2m. It is not allowed to connect directly to the fuel inlet pipe of diesel engine. | |
| 3 | Fuel pipe | The inner diameter of the fuel pipe shall be no less than 10 mm. The fuel inlet pipe shall be installed at the side of the oil tank and more than 15 cm away from the bottom of the oil tank to avoid inhaling diesel oil containing oil sludge and water. The material of fuel oil inlet and return pipe in engine room must meet the requirements of ship rules. |
|
| 4 | Daily fuel tank | The oil outlet level of daily fuel tank is more than 0.5m higher than that of diesel oil pump inlet. The requirements of oil inlet and outlet of daily fuel tank are consistent with pipe diameter. If the diameter of inlet and outlet of oil tank is smaller than the required diameter, reaming is required |
There is one more thing to remind, some countries may have the limitations for the engine must be wet exhaust pipe, yest it is available, but we standard dispatch the engine was with dry type, the heat shield lined with ceramic composite material is installed outside the dry exhaust pipe to reduce the temperature in the engine room and improve safety. and of course the wet exhaust pipe is also available, but the price is expensive USD3185/Pc than the dray type engine, please it should be confirmed before the engine manufacture, for example if now you want the dry type engine, and when you receive the engine want to buy the wet exhaust pipe to change that by yourself, we are sorry could not do that, because not only the wet exhaust pipe different, but the inner cylinder block is different, so be sure let us know before place the order you want dry type or wet type.
