Caution engine preheating, regardless of whether or EFI diesel engine injection diesel engines are required preheating. Because the engine warm-up aims not only to make full combustion of fuel, antifreeze temperature rises, it also has a role in making the formation of a protective film of lubricating oil. 2, the engine warm-up time is not as long as possible. If a long hot car, then the diesel engine will do useful work, not only a waste of fuel and is not environmentally friendly. Diesel engines generally have started work before loading preheat 3-5 minutes is more appropriate. 3, under the cold state to avoid multiple startup and time to start. Diesel engine start times will increase the degree of wear of moving parts, reducing parts and engine life. According to authoritative studies have shown that more than 50% of engine wear is caused due to the cold start, because of wear caused by cold start is not reached due to the lubricating performance, so reducing the number of cold start will extend the life of the engine. 4, the engine warm-up time should check engine-related parts and operation is normal. In the engine warm-up time, you should check the dashboard lights are normal, you should listen to if there is abnormal sound engine, look in the engine smoke is normal. 5, see the tachometer determine whether the normal idle speed. Under normal circumstances, the machine hand just look at the tachometer is working to determine the machine warm-up is complete. Because the thermal expansion of the machine did not reach agreement, the auto governor considers the engine load is relatively large, the speed will naturally high, when the speed is normal, which means that the thermal expansion of the machine to reach consensus a used mini excavators prices, this time It can be identified machine to warm up has been completed. Taian Jia and Heavy Machinery Co., Ltd. excavator oil leakage problem how to repair excavator leakage phenomenon usually occurs in the engine parts, hydraulic components, hydraulic lines and a front work. Engine parts oil, diesel oil leakage may occur. Engine oil leak, resulting in insufficient oil level, it will cause the engine lubrication system does not work well, leading to abnormal wear of internal engine parts, engine damage would cause significant losses excavator customers. Diesel engine leak can cause abnormal consumption of diesel, increasing the cost of the work excavator customers, also increased the equipment fire accident hazard. Hydraulic components, hydraulic lines and front attachment leaking hydraulic oil, mainly in the ring at the hydraulic components, hydraulic rigid pipe and hydraulic hoses place. Hydraulic rigid pipe occurred mainly in the line of engagement surface and O-rings, hydraulic hose failure modes are: pipe surface damage, pipe assembly hardening, surface blistering, kink, pull-out joints, joints leak and so on. Leakage of hydraulic oil price of domestic mini-excavators, causing hydraulic oil tank, this could lead to the hydraulic system does not work, could easily lead to damage to the hydraulic components. In addition, the hydraulic oil leakage will increase the risk of fire equipment. Engine oil, hydraulic oil, oil leakage will severely affected excavators, mini-excavators in order to reduce risk much money, we have what it takes to take preventive measures? We recommend, excavator driver needs to refer to the operation Manual mini excavators, regular engine, hydraulic components, hydraulic lines and a front work to check if the machine operating time is very long, such as 24 hours a day to work, they need to be checked more frequently. Risks need to be more focused on checking the site: high-temperature parts, rough wear parts, bent parts and the like. Before the test, we need to be cleaned checkpoint, remove hydraulic components, piping above the dirt and other impurities. Order inspections, recommended by the pump chamber, control valve chamber, sequential engine, pilot line, a front work carried out, to prevent the omission checkpoint. Once the check lines or O-rings fail leak, the driver will need to contact the dealer service personnel as soon as possible to replace the set piece.泰安嘉 and Heavy Machinery Co., Ltd.-made mini-excavators | mini-excavators | Kerry and Heavy (View) by 泰安嘉 and Heavy Machinery Co., Ltd ..泰安嘉 and Heavy Machinery Co., Ltd.
