Analysis and Solutions for Insufficient Pressure of Steel Pipe Crimping Machine
AtPipe crimping machineDuring the operation of the pipe crimping machine, there are times when the pressure of the pipe crimping machine is insufficient. At this time, we need to analyze the crimping based on the on-site situation, promptly eliminate related faults, and ensure the continuous operation of the crimping work.
1. Pump malfunction
Eliminate pump body faults or replace with a new pump;
2. Pump not adjusted to working state
Please have the technician re-debug the pump;
3. Overflow valve malfunctioning or damaged
Repair or replace the overflow valve;
4. Parts leaking oil
Repair or replace the leaking parts.
If the above fault analysis still cannot find the cause, please contact the manufacturer in a timely manner for further fault analysis of the equipment.
5. After long-term use of the pipe crimping machine, the crimping may not rebound after crimping, affecting work progress. At this time, we should check the problem in a timely manner according to the situation.
Pipe crimping machineIt usually uses hydraulic drive, so there are no issues like spring failure. The possible fault of Z is the control pressure solenoid valve.
If maintenance is improper, the solenoid valve may fail due to excessive oil. Generally, as long as the solenoid valve is disassembled and dust, oil, and other impurities are removed, the solenoid valve can resume operation.
If the problem cannot be solved, it depends on whether the solenoid valve is damaged. If damaged, replace the solenoid valve to resolve the issue.
Benefits of using a pipe crimping machine:
1. The pipe crimping machine relies on the power generated by the hydraulic power source. It not only moves smoothly and returns quickly but also does not lock the mold due to spring return. In addition, the oil cylinder locking system is designed to connect front and back, making it easy to crimp various shaped elbows.
2. The hydraulic system consists of a motor, oil pump, solenoid valve, pressure regulating valve, and hydraulic valve, forming a dual hydraulic oil circuit for front and back movement. In addition, a hydraulic circuit away from the quick release valve is added in the dual hydraulic oil circuit to achieve faster oil return, adjustable speed, reduced noise, and system pressure.
3. In terms of electrical control system, the control circuit is suitable for PLC circuits. It has advantages such as convenient circuit maintenance, easy maintenance, and simple replacement.
4. The crimping die and die base use non-cumulative error processing technology to ensure that the crimping line spacing of the product is uniform after crimping, without size differences at both ends.
5. To ensure the permanent mechanical accuracy and service life of the pipe crimping machine, the locking mechanism components not only use high-quality alloy steel materials but also adopt a unique heat treatment process. Therefore, the long service life of the pipe crimping machine is inseparable from material selection, heat treatment, processing technology, and structural rationality!
6. For dual-column pipe crimping machines and C-type pipe crimping machines, due to the inconvenience of setting dead point positioning, the crimping size must be controlled by CNC.
7. Crimping standards
Theoretical requirements: Do not remove the hose head and damage the rubber inside the hose.
If you do not want to remove the head - the belt crimping pressure should be larger, if you do not want to damage the internal glue - the belt crimping pressure should be smaller.
To resolve this contradiction,Pipe crimping machineit is necessary to first choose a non-conical (0 conical) pipe pressure machine to ensure that the data at the front and rear ends of the hydraulic metal joint is consistent and to avoid errors.
