Answer Upon - Don't Use A Needle Valve To Control Your Air Cylinder Speed!
Business coaching can be very helpful in streamlining business processes, harnessing business potential, and increasing profitability. However, these can only be achieved by using the right kind of business coaching that is cost effective and does not hinder the day-to-day functioning of the business. Before selecting a business-coaching course, it is important that you spare some time for learning about the coaching facilitators, their experience, their areas of expertise, their educational qu
Some folks opt for needle valves to throttle the flow of air into and out of the air cylinder, thereby reducing it's speed. The problem with using a needle valve to control the speed of an
Metal detectors can be employed for a variety of applications in security, humanitarian, and industrial sectors. Metal detectors ratings are helpful for newcomers to choose metal detectors that are apt for them. Generally, metal detectors are rated by cost effectiveness, features, functions and usability.Different types of metal detectors are available. Typical metal detectors come with less features and buttons, but some are more complicated. If a customer wishes to choose metal detecto
Compressed air is 'explosive' as it moves from high pressure to low pressure on it's way back to atmosphere. That means when the air valve shifts and air flows to the cylinder, the cylinder piston and rod moves extremely quickly. A high speed cylinder rod may not be best for your application, and you will want to reduce the speed and the impact.
One easy method of controlling the speed of an air cylinder is installing flow controls in the air lines between the valve to the air cylinder, in the cylinder ports themselves, or even in the exhaust ports of the air valve, though the latter is least desirable.
In the 'valve exhaust' type flow control the controls themselves may be far enough away from the cylinder that the piston and rod may have traveled the full stroke before the exhaust flow control can start back-pressuring the line to slow the cylinder. Cylinder control reaction time is always negatively affected depending on the distance from the cylinder to the flow control.

ISO 9000 is an enormously successful international quality management system set by the international standards organization. Apart from helping in designing a quality assurance system, ISO 9000 also imposes many liabilities and responsibilities on the part of business organizations.ISO certification can guard organizations against corporate vicarious liability. Vicarious liability refers to the legal responsibility (accountability) of an employer for the actions, crime or injury done by

Ok, Here's the question. Is being self-employed all that it's cracked up to be? Ask anyone what they think about people who are self employed and I will guarantee you that the first response will be that they are all "rich". Yup, it's true, every self employed person is rich or suppose to be, baloney! Now, ask that same question of a dozen self-employed entrepreneurs and I bet you that you will hear twelve different responses.Before working for the "man", I was self-employed on the Ea

Water jet machining technology involves the use of high-pressure water jets for cutting parts out of different types of material such as soft rubber, foam, extremely thin stuff such as foil, carpet, paper, cardboard, soft gasket material, candy bars, diapers, and soft wood. Its use is limited, as it cannot cut harder materials such as metals, glass, and hard wood.The water used in water jet machining systems is pressurized between twenty and sixty thousand pounds per square inch (PSI) de

If you've been watching those late night infomercials, you may be convinced that the US government is giving away Free Money to just about anybody who needs some. Your savings and even your home may be at risk if your business fails, so the thought of a free government grant to start your business is very tempting. Grants are given by an organization or local government officers to a business in line with their particular projects success.In return, you have to pay a 2% of your outstandi
Some folks opt for needle valves to throttle the flow of air into and out of the air cylinder, thereby reducing it's speed. The problem with using a needle valve to control the speed of an air cylinder is that it throttles the compressed air flow equally in both directions.
If you are using a larger cylinder, by throttling the air into the cylinder, you are actually preventing the smooth cylinder stroke desired. As air pressure builds in the cylinder it will reach the point where it overcomes the friction of the piston and rod seals and the piston will start to move. As it moves, it increases the volume of the air space inside the cylinder behind itself. The piston moves toward one end of the cylinder creating a larger area behind than in front of it. This is an area into which air has to flow quickly to ensure that the piston keeps moving. If the air inrush cannot keep up with the increasing cavity size there will be insufficient pressure to keep the piston moving, and it will stop. So too will your piston rod, and whatever tooling you have installed on the end of it.
The rule of thumb for using a flow control to reduce and smooth air cylinder piston travel is to only throttle the exhaust air from the cylinder. The air flowing in
