The gantry shearing machine basically uses a hydraulic system. The advantage of the hydraulic system is that it has a stable lifting operation mode, safe to use and very good load capacity. The slower lifting of gantry shears is mostly caused by the failure of the hydraulic system. The troubleshooting of the hydraulic system is as follows:
1. The diameter of the cylinder and the flow rate of the hydraulic oil.
The hydraulic elevator speed of the gantry shear is inversely proportional to the cross-sectional area of the piston rod of the cylinder, and proportional to the hydraulic oil flow. The cylinder diameter is fixed at all times. When the hydraulic elevator speed becomes slow, the hydraulic oil flow should be analyzed first.
2. The hydraulic pipeline of the gantry shear is also a very important link. The hydraulic pump is also an important factor that affects the flow of hydraulic oil. The hydraulic pump that has been used for too long is also prone to problems. When the speed of the hydraulic elevator slows down, it should be checked. Whether the oil supply flow of the hydraulic pump is stable.
Therefore, when the speed of the hydraulic elevator slows down, the factor of hydraulic oil flow should be given priority. In addition, if the quality of the hydraulic oil is not good, there are a lot of impurities, which will also block the speed and slow down, so it is necessary to replace fresh hydraulic oil in time to maintain hydraulic pressure The oil is clean.
