Marine diesel structural advantages 1. Unique frame type main bearing structure, body stiffness, small vibration amplitude, low decibel. 2. A cylinder a cover, easy vehicle maintenance process, reduce maintenance costs consumption. 3. The main components are global purchased, to achieve a high engine configuration. The accessories are completed, air coolers, sea and fresh water heat exchanger mounted on the engine, easy cabin layout. 5. The diesel engine cooling systems inside and outside the two-cycle water-cooled, diesel engine with fresh water circulating cooling, the outer loop water by sea-fresh water heat exchanger for fresh water cooling marine engines, improved diesel engine service life. 6. improve the protection and control systems, the use of diesel function monitoring device, can automatically measure the speed, water temperature, oil temperature and pressure of the diesel engine display, when the engine parameters overrun automatic alarm and shutdown, optional remote control device. 7. A good design, the use of the water jacket exhaust pipe to keep the cabin temperature is low. 8. supporting good adaptability, WD615C, WD618C series diesel engine flywheel, flywheel housing, diesel monitoring instruments, the water jacket exhaust pipe, sea water pump and other components common. Diesel engine installation size, flywheel and flywheel housing dimensions are the same, to facilitate the support and maintenance. 9. front of the crankshaft There are pulley grooves and connecting flange for customers to connect the power output device. No one bush-burning diesel Edit seasonal use of lubricants. Different seasons should use different grades of oil. Some diesel bush-burning, because summer is the use of small viscosity oil marine engine manufacturer, in bearing contact surface can not form a film due. Second, the lubricating oil dirty. If dirty oil added to the body, it will cause clogging of the oil bush-burning. Third, pay attention to observe the instrument. When the diesel engine oil pressure should be normal (0.15 to 0.25) between MPa, idling engine oil pressure not less than 0.5MPa. Many machine hand rarely pay attention to see the oil pressure gauge, and therefore can not be found hidden faults. The fourth is to add the right amount of oil is not. If too much oil, easy to burn the oil when the engine is running, the formation of carbon, if too little marine engine sales, due to poor lubrication is bush-burning axle. Usually the oil surface in the most appropriate scale up and down between the dipstick. Fifth, long-term overload caused by bush-burning. Because long-term overload operation, engine temperature, low speed, carrying capacity increased bearing Shandong marine engines, a corresponding reduction in the fuel supply pump, coupled with lower oil viscosity at high temperatures, more likely to cause bush-burning. Sixth, with the gap between the shaft and tile does not meet the standards. The gap is too small, the oil is not easy to enter, can not form a film layer, the gap is too large, easy to drain the oil, the oil film layer is difficult to form. Therefore, when the repair assembly must be guaranteed within the standard range of bearing clearance. Small marine engines, Weifang Huadong (certified), marine engines supplied by Weifang Huadong Engine Co., Ltd. Weifang Huadong Engine Co., Ltd. (www.hdchai.com) is an industry leader in Shandong Weifang, the internal combustion engine, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Weifang Huadong leadership with the staff warmly welcome all inquiries negotiations to create a better future Weifang Huadong.
