Possible causes and troubleshooting of hose crimping machine failure The special shrinking machine for steel pipes and iron pipes is designed and manufactured with hydraulic component technology, which has the advantages of small size, light weight, compact structure, simple operation, advanced oil circuit design, high efficiency and reliable performance. The crimping machine manufacturer also added the following functions to the design and structure: 1. Completely replace manual welding; 2. Increase the positioning device to solve the problem of different lengths of reduced diameters of steel pipes and iron pipes; 3. Re-improvement of the shrinking stroke, which greatly improves the production effect, and the daily work efficiency is 3,000 to 5,000; 4. Small size, less floor space, easy to move; 5. The special mould has high precision and no steel pipe will appear after the head shrinks. Common failures and troubleshooting methods of pipe presses (also known as pipe locking machines): possible causes and troubleshooting methods for common failures of pipe presses. For example, the motor does not rotate after the pipe press is energized, and the possible cause is that the power supply is out of power. Troubleshooting 1. Check Whether the power switch is off. 2. Check whether the contactor is closed. 3. Check whether the fuse is blown. 4. Check whether the thermal relay is disconnected. The motor rotates but does not work. The possible cause is the lack of phase in the power supply. 1. Check whether the fuse is blown. 2. Check whether all three wires are energized. Possible causes and troubleshooting methods for motor reversal: Reverse any two phases of the three-phase power supply. The possible causes and troubleshooting methods of the lock nut of the pressure regulating valve are loosened. After the pressure regulating valve is tightened one turn, the nut is locked. Possible causes and troubleshooting methods for insufficient hydraulic oil, check whether the oil level is at the liquid level line. The electromagnetic reversing valve does not work (when checking, the scale must be adjusted outside the working range, possible causes and troubleshooting methods), check whether the electromagnetic reversing valve is energized, or check whether the electromagnetic reversing valve is stuck.
