50 ton hydraulic press installation steps

The installation steps of 50 ton hydraulic press are as follows:

 

1. Place the hydraulic pad on the workbench, and then place the movable workbench on it. Insert the columns into the four holes on the slider and workbench, then install the power supply mechanism and electrical cabinet and make a level, and finally fix the anchor screws to the ground.

2. During this period, hang the master cylinder and upper beam and put them into the column, block the piston of the master cylinder to prevent the piston from falling and causing accidents when completing the installation work, tighten the nuts, and then take off the fasteners.

 

3. Connect the official channels, circuits, stroke limit devices, etc. according to the appearance diagram, hydraulic theory diagram, electrical theory diagram, etc., and inject the appropriate amount of oil into the cleaning tank. The recommended oil amount is about 1200L.

 

4. Unscrew the oil valve of the pump, fill it with oil to eliminate the air in the pump, and loosen the handle of the pressure regulating valve (safety valve). So far, almost all preparations for machine testing have been in place.

 

5. Turn on the power to start the motor, and its steering should meet the specifications. Otherwise, replace the power connector, officially start the motor, and let the oil level run without load.

 

6. Turn the switch to the "Adjust" position, press button SB8, and let the main piston move downward. The piston head must be correctly inserted into the positioning hole of the slider, and then install the connecting nut between the piston and the slider, leaving 3 - 5MM gap connecting flange, adjust the pressure valve to increase the pressure in the master cylinder to 5MPa, and use a wrench to fix the connecting nut in the pressure maintaining state.

 

7. Press the SB9 button to make the slider stroke backwards. Place the two pressure test plates on the workbench. The center of the plates is under the piston rod. The test plate size is F320*650 (MM). The upper and lower parts should be parallel, and the parallelism error Not less than 0.02/500MM, the plate should withstand a pressure of more than 500T, then adjust the parallelism and verticality between the slider and the workbench, and finally fix the upper beam and fastening nut.

 

8. Test under loading conditions, refer to the hydraulic theory diagram, adjust the rear valve pressure until the slider does not slide in any position, and pay attention to the pressure not being too high. When the upper chamber pressure of the master cylinder is less than 1MPa, it will decrease most slowly. The pressure range is controlled between 5MPa-25MPa, that is, it is divided into three times from 80T to 500T.
