Fibre Cement Rebar Spacers machine in the molding process hydraulic cylinder output different strength, cement product appearance size is different.

Therefore, the pressure output of the Fibre Cement Rebar Spacers machine needs to be adjusted.

Pressure adjustment method of Fibre Cement Rebar Spacers machine, pump station adjustment 1. No-load operation for 10-20min. When starting the hydraulic pump of the block machine, loosen the overflow valve or be in the unloading position, so that the system can operate without pressure.

Look at the magnitude of the unloading pressure;

Whether the operation is normal or not, there is no harsh noise;

Whether there is too much foam in the tank, whether the oil level is within the specified range, etc.

Adjust the overflow valve, gradually step up the pressure, 3-5mpa per gear, and lOmin per gear, until the set pressure value of the overflow valve is adjusted.

Pay close attention to the pressure difference before and after the filter. If the pressure difference increases, replace or flush the filter at any time.

Adjust the unloading valve of the duplex pump to make it 15 to 20 percent higher than the actual pressure required for fast travel.

Adjust the pressure reducing valve on each branch, make the outlet pressure of the pressure reducing valve reach the required standard value, and observe whether the pressure is stable.

Adjust the sending pressure and return interval value of the pressure relay to make the sending value 0.3-plus higher than the operating pressure of the actuator controlled.

The return interval value is generally 0.35-0.8mpa.

When it is found that the system pressure is too low and the cement pad is maneuvering slowly, the system pressure of the small pump overflow valve and the large pump proportional valve are checked respectively according to the pressure of the pressure gauge of the pump and the action of the equipment.

The pressure adjustment under the mould is too large, it is necessary to reduce the pressure of the independent pressure regulating valve corresponding to the oil cylinder on the bottom supporting mould gradually, until the vibratory force of the cement brick making machine can be fully developed.
