The hose crimping machine(i.e pipe locking machine) DSG-250A&B made by our factory is adopted to the locking of high-pressure plastic pipe, fibre pipe and rubber pipe. This machine owns many advantages, such as small dimension, small weight, multifunctional,fast die-opening, easy to operate and repair.

1). Transportation: the machine should be transported with fork-lift truck.

2). Installing: the machine should be fixed horizontally on the firm foundation and undertake ground connection treatment.

3). Oil injection: open the back cover of the machine case and inject 56 liters No. 46 antiwear hydraulic oil.  

4). Electricity connection: connect the power-line with the machine prescribed electric source. Inch the electric motor and observe the rotation direction. The rotation direction of the electric motor should be consistent with arrow direction on the label of electric motor. Or after connecting the line, switch on the power switch. If the machine acts, the mould opening enlarges, this means that the rotation direction of the electric motor is right. If the machine doesn’t act, it is necessary to exchange the random 2 lines of the 3 live wires.

5). Pressure adjustment: the maximum pressure of the machine system is 31.5MPa adjusted by spill valve. Adjusting clockwise the pressure increases. Adjusting anticlockwise, the pressure decreases. (When leaving the factory, the pressure has been finished adjusting. If needing to adjust the pressure of spill valve, using this equipment exceeding 31.5 MPa is strictly prohibited)
