Excavators at low status of equipment maintenance has caused the majority of drivers attention. In fact the main problem equipment used at low temperatures and difficulty in starting the engine assembly badly worn. 1. The minimum start speed is usually cold start engine can be started at a certain temperature to represent the temperature startup performance, and said its low-temperature start-up performance with the lowest temperature of the engine can be started. The main types of start-up performance of the engine, combustion chamber design, process levels. In the course of second-hand excavator price, engine cold start of the engine oil viscosity mainly by evaporation of petrol or diesel, the cold flow properties of diesel and battery capacity to work in. Drag torque of the engine crankshaft rotation speed and starting at low temperature is mainly affected by the impact of lubricating oil viscosity. As the temperature drops, the oil increase friction, the engine drag torque increases, so that the time required to start the engine power increases. Influence of fuel on engine start-up performance is mainly its evaporation. As the temperature decreases the viscosity and increases the relative density of gasoline; diesel fuel reduced mobility at low temperatures, the viscosity increases the price of new excavator, causing poor atomization of diesel, the combustion process deteriorates. After the temperature was further reduced because the fuel precipitate wax precipitation, mobility fuels will gradually lost. If the diesel fuel contains water, winter may also cause the formation of ice within the supply system is not working. Therefore, the need for diesel precipitation and filtration before use. 2. Low temperature wear in the engine cycle, 50% of cylinder wear occurs during the startup process, and a greater impact on cold start engine wear. Engine cold start, the cylinder wall wear serious main reasons: during the boot process, the cylinder wall lubrication conditions are poor; cold start, most of the fuel in a liquid state into the cylinder, the cylinder wall scour film. How to extend the life of the excavator? A: The proper use of the excavator, the strict implementation of safety technical operation, the implementation of target cost management of mechanical equipment, the excavator operator's economic and royalties linked to passive excavator driver change daily maintenance of equipment is an active routine maintenance. Two: to reduce the environmental climate to wear invisible excavator caused a reduction of environmental factors affect its life. Since most construction machinery are open-air operations, operational sites change frequently, so its performance is affected job site temperature, environment, climate and other factors greatly. Mechanical long-term fixed job, must have shut the room (shed), or take on the cover, with the timber support pads under maintenance measures to reduce sun and rain, corrosion and wear caused by invisible. Many construction units due to the neglect of the influence of environmental factors on the use of mechanical (ambient temperature is too low excavator price list, but also to mechanical disastrous consequences). Three: excavator of the periodic maintenance is the key to extend the life. "The Ministry of Road Machinery warranty procedures" for the maintenance of the excavator are clearly defined, however, a number of construction units to the tight schedule, the task is heavy, often overlooked maintenance that machine running, no faults, no need to stop maintenance. This laid the cause future mechanical accident risks. Because maintenance can eliminate the mechanical problems, if not timely maintenance excavator price, tend to make big mechanical equipment failures, accidents or even personal injury forget. This will not only increase maintenance costs, but also delay the construction period. Four: the use of advanced machinery maintenance and other auxiliary detection means. Machinery maintenance work is to extend machine life an important part of the use of reasonable maintenance methods can effectively extend the service life of machinery. According to statistics, the use of advanced condition monitoring tool that can be reduced by 25% to 50% service charge, the failure rate by 75% and extend machine life.泰安嘉 and Heavy Machinery Co., mini excavator price, Kerry and heavy industry, Zhangjiakou excavator price offered by 泰安嘉 and Heavy Machinery Co., Ltd ..泰安嘉 and Heavy Machinery Co., Ltd.
