Low temperature makes it difficult to start the engine, mainly due to the increase in the viscosity of the lubricating oil, the decrease in the working capacity of the battery and the poor atomization of the fuel.The viscosity of the oil increases as the temperature decreases, and the flow performance deteriorates, thereby making the engine lubricating conditions worse, and the rotational resistance of the crankshaft increases.

The walk behind road roller can be used to compact soil, asphalt roads, sidewalks, bridges and culverts, parking lots, sports fields and narrow sites. The vertical vibration, large excitation force, and high compaction efficiency are the roads and municipal departments' Ideal equipment for streets and squares.

Troubleshooting method of roller vibration system The roller manufacturer said that the roller vibration system fault mainly manifested as no vibration or weak vibration. According to the form of pump motor, the system is divided into: gear pump, gear motor, vibration valve system and plunger pump, plunger motor system.

Due to the influence of the processing, assembly and adjustment of the parts of the new Backhoe Loader equipment, the friction surface is rough, the contact area of the mating surface is small, and the pressure bearing condition of the surface is uneven. During the operation of the equipment, the concave-convex parts of the part surface are embedded and friction with each other, and the worn metal debris continues to participate in the friction as abrasive, which further accelerates the wear of the fitting surface of the part. Therefore, during the running-in period, it is easy to cause the wear of parts (especially the mating surface), and the wear speed is fast. At this time, if the operation is overloaded, it may cause damage to parts and early failure of the loader.

China's railways will implement their fourth-quarter train operating charts from midnight on Oct 11, CCTV reported. After the map adjustment, 5286 pairs of passenger trains are running on the whole route, 21 pairs more than the current map. There are 10,829 pairs of freight trains in operation, an increase of 41.5 pairs compared with the current figure.

The policy will promote the accelerated development of the intelligent equipment industry.
