Hydraulic Shearing Machine,How to Solve the Hydraulic System Heating Problem
In order to get the best start-up parameters, it is necessary to repeat the test in the commissioning stage of the soft starter of the hydraulic shearing machine, which will greatly increase the start-up times, which inevitably leads to the overheating of the soft starter. 4 steps for you to solve the hydraulic system heating problem of hydraulic sheari
1. The cooling fan of the electric control cabinet of the soft starter of the hydraulic shearing machine should be running all the time, so that the power thyristor in the soft starter can dissipate heat smoothly and reduce the junction temperature.
2. There should be a 10-15 minute interval between each start of the shearing machine, so as to cool down the power thyristor in the soft starter, so as to avoid the soft starter alarming due to overheating.
3. In the hydraulic system with hydraulic oil as the force transmission medium, the flow velocity of each part is not the same in the process of hydraulic oil flow, which makes the internal friction in the oil cylinder, and then leads to the steady rise of the hydraulic system and the “heating” fault.
4. “Heating” is an inherent feature of hydraulic system, which can not be eradicated. As long as the temperature is kept under a certain threshold, it will not affect the service life, so it is mainly controlled. The use of high-quality hydraulic oil, hydraulic pipeline layout as far as possible straight line, pipeline accessories, valves can maintain a big brand.
