How to adjust the pressure during the operation of the automatic feeding mixer?
1. Check whether the hydraulic pump can output hydraulic oil. If it is a new type of hydraulic pump without hydraulic oil output, the pump body may have casting defects, so the suction chamber is connected with the hydraulic chamber, the oil pressure drops, and the manufacturer should replace it in time. If it is not a new hydraulic pump and there is no hydraulic oil output, the pump may not be operated correctly and the parts may be severely worn or damaged.
2. If the hydraulic pump has oil output, please check whether the safety valve works normally. If it is abnormal, the valve in the pressure oil circuit may be contaminated or blocked due to other reasons, and it is in the oil return position, resulting in a short circuit between the pressure oil circuit and the overflow circuit, or the pipe joint may be loose or pressurized. The leakage of some valves in the oil circuit is serious. Maybe the seals of hydraulic cylinder and hydraulic motor are damaged, which leads to severe leakage.
3. If the output flow of the hydraulic pump decreases obviously with the increase of the pressure, but the pressure does not reach the specified value, it is due to the increase of the clearance after the wear of the hydraulic pump.
4. If the whole hydraulic system of the automatic feeding mixer can establish normal pressure, and there is no pressure in some pipelines or hydraulic cylinders (or hydraulic motors), it may be caused by pipelines, small holes or throttle valves, directional valves, etc. When blocking, check the pressure and oil one by one to find out the cause and sort it out.
