With the arrival of December, many areas have begun to snow, and the owner of the project will often be difficult to start the excavator, and the problem of fire is not good. In fact, there are many reasons for the poor ignition of excavators in winter, such as: incorrect fuel grade, low temperature, poor atomization of nozzles, battery power shortage, etc. One of the most common reasons for th

What should I do if the Komatsu PC200-8 excavator Bucket Cylinder is naturally reduced?

When repairing construction machinery, some parts and components have strict direction requirements, and only correct installation can ensure the normal operation of the parts. Some parts have external features that are not obvious, and can be installed both positively and negatively. In actual work, the reverse condition often occurs, resulting in early damage of the parts, mechanical failure to

When repairing construction machinery, the phenomenon of indiscriminate use of bolts is still prominent, because the performance and quality of bolts do not meet the technical requirements, resulting in frequent mechanical failures after maintenance.

Engine cylinder compression is a key factor affecting power shortage. The way to judge the compression is simple. Take the S195 diesel engine as an example: shake the crankshaft without decompression. When the compression force is large, shake it up and relax the handle, but do not leave the handle. There is a large rebound force, indicating that the compression force is good, and on the contrary,

When the engine is working, open the mouth cover of the oil, if a thick smoke emerges from the flap, it means that the gap between the piston rings of the cylinder wall is excessively worn or over-limit. If the gap does not meet the requirements, it should be repaired in time. Open the valve cover. If there is green or white smoke coming out from the root of the valve (ie the valve working face),

Electrical system maintenance and precautions hydraulic system maintenance and precautions The hydraulic fluid temperature is still high during and immediately after the operation, so be careful when checking and servicing the hydraulic system.

Special reminder, relative to the car of the age, the car with the breaker for a long time must change the hydraulic oil on time, many of the faults are caused by the hydraulic oil, of course, the hydraulic oil is thicker when the car is cold, so the pressure when the car is cold Basically, the flow rate can be guaranteed. Once the temperature of the hydraulic oil rises to about 60 degrees, the op

check the cylinder seal (1) Check the boom and bucket cylinders: 1. Adjust to the same state as when measuring the natural drop, and the engine is turned off. 2. Operate the boom lever to the lift position and operate the bucket lever to the bucket lift position.
