How to solve the problem that the excavator is unable to work slowly

* : * : admin * : 2021-06-18 17:36:43 * : 51
On the mechanical side, we all know that whether new or used, there will be many problems, such as repair of excavators. In the face of the general trend of excavators, the demand of the excavator repair industry is also growing, below we come to analyze the problem that the excavator is unable to work slowly. First of all, let's solve the problem of some excavators'incapability. 1. Check your engine flexibility first. 2. Check whether the hydraulic displacement is in compliance with the constant power output. That is, in the condition of not affecting the speed, adjust the swash plate angle to reduce the displacement. 3. If the engine does not slow down when the load is heavy and the system speed is normal, it is necessary to adjust the system pressure. Since the hydraulic components of each model are different from the hydraulic system, the pressure of each hydraulic cylinder is also different, just follow the manufacturer's instructions. In fact, to solve the problem, it is important to understand the reasons. In general, when a hydraulic excavator is under construction, according to the load requirements of the operation, the speed is inversely proportional to the load, the general working mode of excavator is one pump, one valve and one load, which is optimized and matched in different working conditions, so it leads to the weakness and slow working speed of excavator. In general, when handling maintenance faults of excavators, they are analyzed step by step, from simple to tedious. When solving the problem of lack of power of excavators, they generally first check the electrical system first, and then check the hydraulic system, check excavator drive system step by step check. Of course, if the excavator is used for many years, or bought a second-hand excavator, excavator speed slow or weak, most of these situations are normal wear and tear phenomenon, general important parts and all parts of the machine will cause the engine power loss, will lead to such problems. There is also a problem, if the excavator suddenly slow down, this situation, you can check from the following aspects, 1, first check whether the circuit fuse or open, 2, whether the pressure is normal, 3, the Piston is stuck, 4, distributor confluence failure, if the above can not be resolved, only the removal of the hydraulic pump to check. General excavator weakness or slow working speed and other problems in the above problems, as the demand for excavators increase, general excavator maintenance knowledge, many users in more than one or two years of experience are more or less know, more excavator maintenance knowledge, you can also check here, periodically update excavator maintenance knowledge and excavator fault analysis.
