Top 5 Hydraulic Mistakes and Best Solutions for Hydraulic Press Machine

-

We will cover the top five most common hydraulic mistakes and best solutions for hydraulic press machines. Here are the top five:

1.  Hydraulic Pressures Are Improperly Set

On every hydraulic system there is a multitude of adjustments to be made. When a hydraulic press machine problem occurs, knobs on the hydraulic pump and valves are adjusted to “see” if this solves the machine problem. Unfortunately, the person doing the adjusting usually has no idea what the effect will be on the machine. Pressures in a hydraulic system typically are set too high. The thinking is that the higher the pressure, the faster the machine will run. Consider the following real-world scenario that occurred at a wood products plant.

2.  Lack of Accumulator and Hydraulic Safety Procedures
When a hydraulic press machine is repaired, the pump’s electric drive motor is turned off and lockout/tagout procedures are performed. The pressure gauge is rarely checked before work is begun on or around the machine. Accumulators store hydraulic energy in the form of pressurized fluid. Most systems contain an automatic or manual dump valve that will allow the high-pressure fluid in the accumulator to dump to the tank, permitting the pressure to drop to zero. The automatic dump valves can fail closed, which will maintain the pressurized oil in the accumulator.
3. Poor Troubleshooting Techniques
In our hydraulic press machine workshops, we stress that the quickest and easiest method of troubleshooting a machine is to use a hydraulic schematic. The response from students is usually one of the following: “Management won’t give us time to troubleshoot,” “We don’t have or know where our schematics are,” or “We don’t know how to read the schematics.”
4. Poor Hydraulic Reservoir and Oil Maintenance
While most hydraulic press machine manufacturers do a good job of maintaining system filters, the reservoir usually is not given any attention. When a system is designed, the reservoir size is factored into the amount of heat that will be removed from the system. Reservoirs should be cleaned a minimum of once a year to allow some of the heat in the oil to be released to the atmosphere.
5. Component Replacements Don’t Have the Same Part Numbers
When a hydraulic press machine problem occurs, usually one component has failed. It is essential to match the part numbers between the new and old components. Hydraulic pumps and valves that look alike are not necessarily the same. Each number or letter in the part number indicates a feature about the pump or valve. If one letter or number is different, the manufacturer’s literature should be consulted to identify the difference.

Hydraulic Press Machine Speed Slow How To Solve

  If your  hydraulic press machine  speed gets slowly,following are methods to solve it. 1. Air in the hydraulic cylinder When the hydraulic press machine pressing speed gets slowly, we should first consider that air in the hydraulic cylinder, interrupt the corresponding exhaust operation through the exhaust equipment of the machine, and check whether there is air in the movement direction of the piston rod. If so, it may be If the sealing ring is defective, the sealing ring should be changed in time. 2.  Check whether the hydraulic pump is operating normally When the hydraulic press machine moves slowly and the hydraulic pump runs irregularly, and sometimes it may be blocked or slightly seized, it means that there is a problem with the hydraulic pump and the hydraulic pump should be repaired or changed in time. 3. Check the operation of the piston When the hydraulic cylinder of a hydraulic press machine with a buffer device is intermittently started in reverse, the piston will be temp

Hydraulic press offers several benefits when it comes to manufacturing components for AI servers forming: AI server forming ○ Precision and Consistency Hydraulic press allows for precise and consistent shaping of metal components used in AI servers. This is essential for ensuring that the parts fit together correctly and function optimally within the server system. ○ Complex Shapes Hydraulic press enables the creation of complex and intricate metal parts that may be required in the construction of AI servers. This is particularly important as servers often contain components with non-standard shapes to accommodate various functionalities and space constraints. ○ Material Strength The process of hydraulic press can enhance the strength and durability of metal components used in AI servers. This is crucial for ensuring the reliability and longevity of the server hardware, especially in high-demand computing environments.
