Debris in the seat of a valve can be an indication that there is a pending catastrophic failure in your hydraulic system. I have noticed that it's common for machinery and equipment manufacturers to recommend in their respective service manuals that maintenance workers that troubleshoot their hydraulic systems should "disassemble and inspect" valves like check valves and pressure control valves to see if their is debris in the seat. I strongly advise manufacturers in the U.S.A. to withdraw these recommendations from their service literature for several reasons: 1. There are no schools in America that are equipped with the correct tools and information that enables them to teach students how to "disassemble and inspect" hydraulic valves. 2. Many cartridge type valves cannot be disassembled because of their design. 3. If they are in the field and there is mud or snow, the internal spring could unexpectedly eject the spools and other small parts, which might never be found. 4. There is a strong possibility the person doing the recommended procedure could assemble the valve incorrectly, which could cause it to malfunction. If it's a pressure relief valve, a malfunction could cause the worker to suffer severe injury, death and or substantial property damage. As we well know, if you made the recommendation - verbal or written, and the person gets injured or killed, it's highly likely you are going to spend years defending your company in court. 5. If there is debris in the seat of a valve, pause to consider how it got there or where it came from. If you can see it, it's larger than 40 microns. You MUST analyze the composition of the debris because in all likelihood, it's evidence that the pump, which is upstream, is beginning to destruct. Conclusion: Never simply remove debris from the seat of a valve and put the system back into service. It's imperative that you have the debris analyzed and the source identified. If the pump is in the throws of disintegrating, it will eventually fail completely and transport it's harmful "shrapnel" throughout your hydraulic system.

Let us take a moment to think about control valve operation and maintenance. On a valve on gas service, provided the gas is clean, there should be no erosion damage to the control valve trim. So why does the damage, typically shown on the plug shank in the picture below, start to occur? A gas valve will be relatively dry, which means there is no natural lubrication between the plug and the cage. A liquid service valve, however, will naturally have a degree of lubrication through the fluid passing through the valve. The first consideration is that it could be "galling". In simple terms, galling occurs when two relatively soft materials are rubbed together. The rubbing effect causes the materials to "pick up". Galling is normally eliminated by applying a hard facing to at least one of the rubbing surfaces. A typical hard facing material is Stellite 6. So if the materials have been correctly selected, why would the damage shown below still occur? The answer is often line debris. Control valve trims are manufactured to close running tolerances, and if debris gets trapped between the plug and the cage, then this will cause score marks, mostly in the softer material. The scoring often starts to "ball up" the material, which in turn gathers between the plug and the cage. Over the period of operation, as the actuator continues to move the valve up and down, the process is repeated, and the damaged area grows in size.

· Dangers of Leaking Hydraulic Fluid 1.Lower Financial Efficiency If there will be regular or excessive leakages on an equipment probably the cost of production will eventually rise due to spending more money on oil that is being lost through leaks. 2.Severe Damage to the Environment Leaks on machines e.g. hydraulic leaks are very dangerous to the environment and living things. 3.Risk of Machine Components Malfunction Leakages on a cylinder or pumps may result to an equipment malfunctioning hence causing failure on the machine. 4.Risk to Personnel Safety During maintenance technicians have been known to slip and fall due to fluid leaks on an equipment causing injuries to them. 5.Reduced Machinery Efficiency of Hydraulic Systems Multiple hydraulic leaks will always negatively slower cycle time in hydraulic system thus reducing equipment’s efficiency in it’s performance. 6.Risk to LOSS OF PROPERTY Most of the combustible fluids are exposed to heat they might cause fire and ends up burning the equipment due to leakages on an equipment. 7.Oil Consumption Increase A lot of oil is lost from the machine through leakages and this eventually leads to increase of oil consumption on the machine/equipment during operation.

The flushing and cooling of the mechanical seal of the slurry pump are the auxiliary facilities of the mechanical seal and are essential. 1. slurry pump mechanical seal flushing 1) Classification Self-flushing is to use the pressure difference generated by the pump itself or the pumping device in the sealed cavity to generate pressure difference, so that the sealed medium can form a closed circuit through the sealed cavity to realize flushing The circulation flushing circulates the additional sealing fluid through a pumping device, which can be additional or an additional device can be installed in the sealing cavity. Injection flushing, or external flushing, is to inject another liquid into the sealed cavity from the outside to improve the sealing working conditions. This method is suitable for use when transporting media containing solid particles. Most of the mechanical seal flushing of slurry pump is external flushing. 2) Role Used to reduce mechanical seal temperature Ensure good lubrication of the end face of the seal Prevention of vaporization does not cause dry friction In containing solid particles, crystalline medium and strong corrosive medium to keep the seal ring from damage 2. slurry pump mechanical seal cooling 1.)Classification One kind of direct cooling is the cooling liquid flushing mentioned above, and the other is to pass the cooling liquid into the static ring on the gland. The part outside the sealed cavity is called quenching or back cooling. The liquid is discharged and is usually carried out with cold water. Indirect cooling is to add a cooling jacket outside the sealed cavity. The cooling liquid of the cooling jacket is generally cold water introduced from the outside, which forms a slurry pump cooling system with the cooling of the slurry pump bearing. 2.) Role Mainly used to reduce the working temperature of mechanical seals Ensure the normal operation of the mechanical seal of the slurry pump The above is about the slurry pump mechanical seal flushing and cooling of the classification and role of the introduction

Hydraulic Jacks and Rams Need Calibration Hydraulic jacks and rams need calibration for several important reasons: 📌 Accuracy: Calibration ensures that the hydraulic jack or ram is operating at the correct pressure and can lift or apply the correct force. Over time, wear and tear, or internal changes in the hydraulic fluid, can lead to inaccurate pressure readings or force output. 📌 Safety: Improperly calibrated hydraulic equipment can cause accidents, such as overloading or underloading. Overloaded jacks may fail or break under pressure, while underloaded systems may not perform the task effectively. Calibration helps maintain safe operational limits. 📌 Efficiency: A well-calibrated jack operates more efficiently. It will lift loads smoothly without requiring excessive effort, and it will also prevent energy loss or hydraulic fluid leaks that can arise due to misalignment of the system's pressure values. 📌 Compliance with standards: Many industries require equipment, including hydraulic jacks and rams, to be calibrated according to national or international standards. Calibration ensures compliance with these regulations and ensures that the equipment passes inspections. 📌 Longevity of equipment: Calibration can help detect minor issues, such as leaks or pressure inconsistencies, early on, which can extend the lifespan of the equipment by allowing for timely repairs and maintenance. In summary, regular calibration maintains the performance, safety, and efficiency of hydraulic jacks and rams, preventing premature wear and ensuring they meet operational and safety standards.
