When the hydraulic press cannot reach its proper pressure in time or makes strange noises, you may encounter some problems, which means it is time to change the machine. Even repairs with scheduled maintenance on a regular basis may encounter problems due to only a few years of use or problems that the operator may not be aware. Knowing more about how to know when to replace a hydraulic press is essential to avoid production stoppages. This articleZhongyou Heavy IndustryBringWhat failure occurs when the hydraulic press indicates that it needs to be replaced.
1) Pump and pressure relief valve
One of the most common problems in hydraulic presses is leakage. In some cases, the leak may be small and difficult to detect until the leak is larger and causes greater problems. If your press does not reach the correct pressure within the right time, there may be a problem with the pump. If the faulty pump is found in time, then the new pump can avoid the need to completely replace the press. Failure of the safety valve can also cause pressure problems. If there is a problem with the motor of the press, the pressure will also be affected. Experienced press technicians recommend that the owner understand the action and sound of the press when it is running at the best pressure and speed. In this way, any noise or other changes will be immediately apparent.
2) The importance of clean oil
Oil maintenance can help you avoid several major problems in the operation of hydraulic machines. It is important to ensure that the oil is changed every year, because the oil can become dirty and cause lubrication problems. Old engine oil may be full of harmful particles, which can interfere with the smooth operation of the motor. Remember that the ram must not drip oil, but it should always be kept wet for smooth operation. Regular oil inspections help prevent serious and expensive repairs in the future.
3) Electrical fault
The electrical system in the press is another important aspect of maintenance inspection. The valve coil may wear out, and if it is not replaced, it may cause the press to stop. Normally, the valve coil can last 3 million strokes. A relay switch can typically last a million strokes. When the electrical components are operating normally, the press will get enough motor power to produce the correct pressure. When there is a problem with the electrical system, the press may stop or slow down, resulting in downtime and, in many cases, high maintenance costs. It is important to take time to ensure that all electrical components on the press are in good working condition to maintain uninterrupted production.
4) Hose and crimping
The hydraulic hoses must be properly maintained, otherwise the press will lose pressure. Hydraulic oil leakage can also be a safety hazard in the workplace. Hoses should also be checked regularly for cracks and abnormal crimping. Crimping problems can cause piping problems that directly affect the pressure of the hydraulic press. Hoses should always be under the care of a trained professional. Proper crimping ensures that the hose can withstand the pressure used by the press with which it is associated. Ensuring regular replenishment of hydraulic oil is also important for smooth operation and enabling the press to reach the correct pressure level.
5) Cracked framework
The frame cracks may be subtle, but they still cause serious problems in terms of absorption and smooth stamping function. Fatigue cracks can start small and continue to extend during continuous use, causing the key to function out of balance for the disconnected state. Welding frame cracks usually only provide temporary repairs, giving you time to arrange a new press. If you are not sure about the correct welding of the crack, it is best to contact an expert. However, you can also consider buying new news surplus from reputable, trusted manufacturers on top of the production and take advantage of competitors.
6) Be with the new, be with the old
When a hydraulic press needs to be replaced, knowing the time is essential to prevent downtime in production. This is another important reason to fully understand your machine through regular maintenance. Many machine processing plants and other industries rely on parts made by hydraulic presses. This is why it is important to know when to replace a hydraulic press.
