The scrap steel shearing machine can be seen from the name that it is used to cut scrap steel, but the shortage of workers is indeed a headache, which will directly lead to the suspension of production.
Insufficient shear pressure should be resolved from the following analysis:
1. Determine whether the oil pump is leaking, if it leaks, replace it;
2. Check the integrated block under the electromagnetic, if possible, it can be cleaned with diesel;
3. Observe that the circuit of the scrap steel shearing machine may participate in the hydraulic control check valve. When the oil cylinder drops, the closed loop pressure of the hydraulic control reduces the check valve. When the hydraulic pressure is controlled, the one-way valve of the scrap steel shearing machine is opened;
4. If the working pressure of the hydraulic system is low, adjust the pressure to the extra working pressure.
