When the hydraulic brake is in use, the power supply of the electro-hydraulic push rod is generally connected in parallel with the power supply of the main-stage moving motor of the equipment, and no additional wiring is required, so it is suitable for the 380V three-phase AC power supply and the main motor to start and stop synchronously. When the power is turned on, the main motor starts and runs At the same time, the brake motor drives the impeller to rotate, sucking oil from the upper part of the piston to the lower part of the piston, generating pressure to push the piston push rod up quickly, completing the rated stroke and reaching the specified thrust, the brake shoe opens, and the equipment starts to operate normally. After the power is off, the main motor stops, the push rod impeller also stops, loses oil pressure, the piston quickly drops under the action of external force (spring reset), returns to the starting position, and the brake shoe brakes.

　　For the driving mode whose voltage level is inconsistent with that of the main motor, the push rod motor should take another power image, but pay attention to the realization of interlocking control with the main motor, so as to avoid the main motor due to the power failure of the push rod motor when the main motor is running. Overload or burnt tiles. These are some points that need to be paid attention to when using hydraulic brakes.
