The excavator can't do anything without the tacit cooperation of the boom and forearm. Therefore, whether the arm is weak, stuck or supports abnormally, it will lead to a great reduction in construction effect and efficiency. Then let's take a look at what are the causes of his failure?
cause of issue:
1. The excavator is blocked due to the repair of the oil circuit. From the appearance, the excavator is composed of a working device, an upper turntable, and a walking mechanism. According to its structure and use, it can be divided into: crawler type, tire type, walking type, full hydraulic, Various types such as semi-hydraulic, full rotation, non-full rotation, universal type, special type, articulated type, telescopic arm type, etc.
2. Leakage in the oil circuit, seal failure, poor assembly, loose pipe joints, deterioration of the seal ring, etc.
3. The leakage of the excavator arm spool valve and the cylinder causes the excavator boom to move slowly and fail.
4. Inner leakage of the boom cylinder.
5. There is a problem with the boom spool valve. Excavator repair is the market leader for large hydraulic excavators. Through relentless pursuit of quality and combined with excellent engineering machinery principles, we have manufactured high-strength, long-life machines, Meet the user's various operational requirements in mining.
malfunction repair:
1.First of all, it is necessary to know whether the excavator boom is slow and weak due to the blockage of the excavator oil path.You can remove the excavator boom spool valve body, valve stem and related parts for cleaning. Clean the oil channel of the excavator, install it in a combination after drying, check whether the excavator's arm movement is slow and weak. Does the fault still exist? If it does not exist, the cause of the fault is the blockage of the excavator's oil path. The initiation of engineering projects, construction machinery has experienced rapid growth and improvement in quantity and quality. As the main equipment for mechanized construction, excavator has now become an indispensable construction machinery in earthwork construction operations. Typical mechatronics high-tech 名媛直播.
2. To check the oil path of the excavator, check whether the oil temperature of the excavator is very high, whether the joints of the oil pipes are loose, whether the oil is contaminated and deteriorated, whether there is poor assembly, etc.
3. Leakage in the boom spool valve and cylinder) caused the Hitachi excavator boom to move slowly and fail, requiring some auxiliary methods to check it out.
4. Boom cylinder inspection, you can remove the rodless cavity tubing of the excavator to make the boom cylinder continue to flush oil. If there is working oil leaking out, the life of the excavator hydraulic cylinder is leaking.
