因为工程机械用柴油机都带有常结合的分动箱，发动机一启动，分动箱上带动液建筑机械化综述讨论压泵、转向操纵液压泵、传动操纵液压泵都随着运转，克服低温下各液压系统油粘阻性大，造成机附加阻力增大，选择既能保证良好的润滑传动性能又要低温粘阻性小的油料。
Because the diesel engines used in construction machinery are equipped with commonly combined transmission boxes, when the engine is started, the driving fluid construction on the transmission boxes is mechanized. Discuss the pressure pump, steering control hydraulic pump and transmission control hydraulic pump all run with each other, overcome the high oil viscous resistance of each hydraulic system at low temperature, resulting in the increase of additional resistance of the machine. Choice can ensure both good lubrication and transmission performance and low temperature viscous resistance. Small oil.
压力要控制在一定范围内，U型槽设备进气系统因为高原作业环境空气含尘密度相当于低海拔515倍以上，发动机空气滤清器滤清效率下降，进气阻力加大功率降低，增加保养频度和难度，要经常清理滤清器，滤清效率的降低导致发动机早期磨损并缩短大修期；在沙漠地区作业含尘率更高，在无风的情况下，因为干燥使机器笼罩在尘雾中工作。
Pressure should be controlled within a certain range, because the air dust density of U-groove equipment in plateau working environment is 515 times higher than that at low altitude, the filter efficiency of engine air filter decreases, the intake resistance increases, the power decreases, and the maintenance frequency and difficulty increase. The filter should be cleaned regularly, and the reduction of filter efficiency leads to engine early wear and shorten the overhaul period in desert. Dust content is higher in area operation, in the case of no wind, because the drying makes the machine work in the dust fog.
U型槽设备的广泛应用不仅在实验室中，在其他的地方也同样发挥着重要的作用，就像在蔬菜大棚中的应用，蔬菜大棚很多的地方不好浇灌，人工浇灌不方便，这时在适当的时候进行一些相应的操作，这时就需要使用到U型槽设备了，把U型槽设备使用在大棚的另一头，当水流流到大棚的那头时，U型槽设备可以实现自动换行进行灌溉的作用，很好的起到良好的浇灌的效果，使大棚种植可以更好的进行，发挥着更好的种植效果。
The wide application of U-groove equipment not only in the laboratory, but also in other places plays an important role, just like in the application of vegetable greenhouse, many places in vegetable qitixielou.37ix.com.cnbileiqi.37ix.com.cntanceqi.37ix.com.cnlingxu.37ix.com.cnguodianya.37ix.com.cn baohuqi.37ix.com.cngreenhouse are not easy to irrigate, and manual irrigation is inconvenient. At this time, some corresponding operations should be carried out at the appropriate time. At this time, U-groove equipment needs to be used, and U-groove equipment should be used at the other end of the greenhouse. When the water flows to the end of the greenhouse, the U-shaped groove equipment can realize the function of automatic line change irrigation, and play a good irrigation effect, so that greenhouse planting can be better carried out and play a better planting effect.
