What should I do if Komatsu PC200-7 has weak arms and slow movements? Questions that appear

　　KomatsuPC200-7 is an old equipment that has a common problem of malfunction during use. However, if there is a lack of power in the large and small arms, the equipment cannot be used normally. Most people will think that there is a problem with the hydraulic system, which is related to the problem. The first step should be to thoroughly investigate potential issues. It is more convenient to handle problems caused by circuit and electronic malfunctions. If the entire circuit and electrical control system is functioning properly, then other aspects should be taken into consideration.

The first step is to check whether there is a malfunction in the hydraulic pump and solenoid valve. This reflects some problems. Many domestic maintenance technicians blindly replace various parts when the equipment cannot detect the cause of the malfunction, which not only increases the repair price but also fundamentally solves the problem.

In testing If the working condition of the diversion electronic valve is good, but there are problems with the pressure and pressure difference electronic sensors, it may cause the hydraulic pump to be unable to divert hydraulic pressure properly during normal use, resulting in power failure of the entire equipment. Excavator equipment has many sensors, and KomatsuIf the usage time and wear of PC200-7 or similar 7th generation equipment have reached a certain level of sensor failure and damage, it is impossible to avoid malfunctions and operational failures during use.

It is important to provide all owners with timely updates or maintenance for old equipment that may be functioning properly, but internal electronic system failures may continue to expose various problems with use. And during maintenance, try to find professional mechanics as much as possible,Second hand excavator marketIn maintenance, it is even more important to improve understanding of equipment and machinery. Impulsive, reckless, and reckless actions not only fail to completely solve problems, but also cause irreparable damage to equipment.
