Troubleshooting methods for pipe bending machines and causes of motor heating during operation
1. The manual hydraulic action rod is powerless to push out and cannot bend the pipe. Firstly, check if the steel ball inside the switch has fallen off. Secondly, tighten the switch clockwise. Check if the hydraulic oil in the tank is full and fill it up. Loosen the bolt on the fuel filler neck. Replace the YX shaped polyurethane sealing ring inside the plunger pump.
2. The column cold pump may have suction or oil cannot be sucked out. Remove air from the fuel tank. The fuel tank is low and needs to be filled up. The oil number does not meet the requirements, please replace it with N15 mechanical oil. The pipe bending machine in the oil filter has garbage and needs to be cleaned. The oil filter can be removed using a large adjustable wrench. Wash the garbage on the copper wire mesh with gasoline.
3. Lift the manual hydraulic handle and gradually lift it. Extend all the manual hydraulic action rods, or when there is pressure on the plunger pump during bending work, tap the handle seat at the front end of the handle with a hammer.
Although the heating of the electric motor during the operation of the pipe bending machine usually does not affect the lifespan of the motor and is ignored by most customers, it can burn out the motor in severe cases. To determine whether the motor of the hydraulic pipe bending machine is burnt out, it is necessary to smell whether there is a burning smell. Open the junction box, remove the end connector, and use a multimeter to measure whether there is a short circuit in the three phases. Short circuit between turns should be measured using an electric bridge and ground resistance should be measured using a shaking table; Can the motor temperature of the hydraulic pipe bending machine be very high. Hydraulic pipe bending machine is a widely used cutting equipment in machining, which can cut steel plates of various thicknesses.
When the hydraulic system of the pipe bending machine leaks, the number of oil pipe joints can be reduced, and the integrated control valve can be used to avoid system oil leakage; To reduce hydraulic impact and mechanical vibration during reversing, try to extend the reversing time as much as possible; The pipe bending machine needs regular inspection, maintenance, and timely disposal to avoid leakage.
During the operation of the pipe bending machine, the hydraulic system may sometimes generate heat. The internal reason for this is due to unreasonable system design, such as unreasonable matching between components, narrow pipeline channels, multiple bends, small bending radius, and insufficient oil tank capacity; The external cause is the hydraulic system caused by improper oil quantity.
The pipe bending machine adopts a touch screen and CNC module, with dialogue operation and simple and easy program setting.
