28/7/2020· by Servo Kinetics Inc Editorial Staff | Jan 31, 2020 | Hydraulic Pump Repair, Industrial Hydraulic Repair The manufacturing of fluid power components is a $23.5 billion industry in the United States.1 The hydraulic pump market alone was valued at $9.78 billion in 2019 and is expected to grow to $12.59 billion by 2025.2 This projected growth will be fueled by
Improper installation can cause cuts or dents in the dynamic lip of the seal, which affects hydraulic seal efficiency as well as introduces foreign elements into the hydraulic fluid. Fracture
A subset of 44 failed spring operated pressure relief valves (SORV) from a set of over 5600 Process Equipment Reliability Database (PERD) proof tests was subjected to root cause of failure analysis (RCA). This paper reports on the findings of those 44 analyses and
The H6 Series hydraulic hose is equipped with a tough abrasion resistant cover and offers a wider temperature range than conventional medium pressure hydraulic hose. H6 hose features a low length change under pressure.
5 Whys is a root cause analysis tool for helping teams quickly get to causes of an issue before developing solutions. It’s a great team-builder because the group buys-in to the *real* problems as they surface during the process.Don’t debate each point to death.
I n the not too distant past, most senior level managers would cringe when someone said a failure mode and effects analysis (FMEA) needed to be performed on the hydraulic system. What immediately came to mind is a bunch of highly paid people sitting around a table dreaming up ways to eliminate things that may or may not happen to their hydraulically operated equipment.
Even greater increases in load will cause the part to actually break. Figure 1 illustrates a very basic point of design, and applies when the load on a part is relatively constant, such as the load on the frame of a building or the stress in the legs of your desk.
Failure Analysis: Analyze equipment failure to determine root cause and prevent costly reoccurrence. Component Repair and Overhaul: Prolong the service life of costly equipment by repairing and/or overhauling serviceable components.
Hydraulic Constant Working Pressure Hose 4000 PSI - GlobalCore 722 Hose | #722TC-12 With 4,000 PSI constant working pressure hoses, half SAE bend radius, and three cover options, Parker’s 722 GlobalCore hose delivers maximum performance and efficiency.
MJ Hydraulic is a stocking distributor of the Gates connected range of hydraulic hose and hose ends. We carry a large quantity of hydraulic hose types with rated pressures up to 6000 PSI from 1/4″ through 2″ diameter along with 700 Bar rated hoses for high pressure jacking equipment.
In the present case study, failure analysis of a piping system that ruptured during hydraulic testing has been carried out to find the root cause and determine the mode and mechanism of failure. Chemical composition of the pipe was found to be in compliance with the standard composition of AISI4130. The failure cause of the pipe has been investigated through visual examination, microstructural
and root cause analysis (FRCA) regarding external oil leakage issues of hydraulic operating mechanism for GIS, reported to a manufacturer as one of failures June of 2016. See figure 2 for failure effects of this reported leakage issue. FRCA process flow shows 2a
Hose asselies are critical to the hydraulic system and must be maintained regularly and monitored for any signs of wear. A hose failure can turn into a component failure or cause machine down-time. Hose types: Hydraulic Fuel Refrigerant Water Grease lines
Skilled in leading root cause failure analysis, developing action plans and managing implementation. Develop and implement strategic repositioning, restructuring of hydraulic hose manufacture, testing and installation, gaseous systems and full operational
While multiple issues can occur that will lead to a premature coupling failure, it is a good idea to start with the alignment of the machinery when determining a root cause. Used properly, dial indiors (lower cost & pictured above) and laser alignment tools (premium/higher cost) are both effective tools to consider when aligning a coupling.
Hydraulic Troubleshooter: Skill • Trace a hydraulic circuit to 100 percent proficiency • Set the pressure on a pressure-compensated pump • Tune the voltage on an amplifier card • Null a servo valve • Troubleshoot a hydraulic system and utilize root cause failure
The need for hose replacement is a fairly common occurrence on hydraulic machines. Hydraulic hose fabriion is a big business with plenty of competition and more than a few cowboys running around. So if you own or are responsible for hydraulic equipment, where you source replacement hoses from, and how they''re made, cleaned and stored - prior to installation on your machine, warrants your
On June 5, 1976, the Teton Dam in in Idaho failed, killing 11 and caused hundreds of millions of dollars in damage. Read our root cause analysis example to learn more about this disaster and the lessons that can be learned from it.
Expert has over 26 years of experience in the design, development, manufacturing and failure analysis of hydraulic and industrial hose. He is very familiar with methods of hose extrusion, reinforcement and vulcanization, having worked with hose made from rubber, thermoplastics and PTFE, and reinforced with wire, polyester, polyamide and aramids.
Companies often turn to training, or retraining, as a quick and easy solution for a human error, when the real cause may be a deeper, systemic issue that could be revealed through root cause analysis (RCA). “Training is thrown at problems when it is not even
