As a key equipment for connecting hydraulic hoses and fittings in the industrial field, hydraulic hose crimping machines will inevitably encounter various failures during long-term use, which affect production efficiency and product quality. Timely and accurate troubleshooting is crucial to ensuring the normal operation of the equipment. This article will provide you with a detailed introduction to the common fault troubleshooting techniques of hydraulic hose crimping machines.
Inaccurate Crimping Dimensions
When it is found that the crimping dimensions of the hydraulic hose do not meet the standard requirements, first check the mold of the equipment. The mold may be worn or deformed after long-term use, resulting in deviations in the crimping dimensions. Carefully observe whether there are obvious scratches or dents on the surface of the mold, and replace the mold in a timely manner if any. Secondly, confirm whether the pressure parameter settings of the equipment are correct. Excessive or insufficient pressure will affect the crimping effect. The pressure value can be reset according to the specifications of the hose and fitting with reference to the equipment manual. In addition, the pressure sensor in the hydraulic system may also fail, leading to inaccurate pressure display, which requires calibration or replacement.
Unusual Noises During Equipment Operation
The occurrence of abnormal noises during the operation of the equipment may be due to problems with multiple components. If transmission components such as gears and chains lack lubrication or are severely worn, friction noise will be generated. At this time, check whether the lubrication system is working normally, add or replace lubricating oil in a timely manner, and repair or replace the worn transmission components. In addition, the failure of the hydraulic pump will also cause abnormal noises. Check the working status of the hydraulic pump and see if there is cavitation, such as too low oil level in the fuel tank, air leakage in the oil suction pipeline, etc. It is necessary to supplement hydraulic oil and repair the air leakage part.
Crimping Machine Not Moving
If the hydraulic hose crimping machine does not move, first check the power supply and circuit system. Check whether the power plug is loose, whether the circuit breaker is tripped, and whether the components such as relays and contactors in the control circuit are working normally. Repair or replace the damaged electrical components. Then check the hydraulic system. Insufficient hydraulic oil will cause the equipment to fail to work normally, and it is necessary to add hydraulic oil that meets the specifications. At the same time, blockage or jamming of the hydraulic valve will also cause the hydraulic oil to fail to flow normally. The hydraulic valve can be cleaned, and a new hydraulic valve can be replaced if necessary.
Oil Leakage Problem
The occurrence of oil leakage in the equipment will not only waste hydraulic oil but also affect the performance of the equipment. Check whether the oil pipe joint is loose, and tightening the joint again can solve the problem. If the oil pipe is damaged, the new oil pipe should be replaced in a timely manner. In addition, aging and damage of seals are also common causes of oil leakage. It is necessary to regularly check the status of the seals and replace the aging and damaged seals in a timely manner.
Mastering the troubleshooting techniques of hydraulic hose crimping machines can help users quickly solve equipment problems and reduce downtime. In daily use, doing a good job in the maintenance of the equipment can also effectively reduce the probability of failures.
