What JIC means?
Just in Case
What is JIC in business?
Just in case (JIC) is an inventory strategy where companies keep large inventories on hand. This type of inventory management strategy aims to minimize the probability that a product will sell out of stock.
What is the best way to check for hydraulic leaks?
How should I check for leaks in hydraulic hoses?
- Before looking for the leak, shut off the power source to the hydraulic pump, and lower the implement to the ground.
- Relieve the pressure of the hydraulic system by moving the hydraulic control lever back and forth.
- To locate the leak, pass a piece of cardboard or mirror over the area where you suspect the leak.
What would happen if a hydraulic system had a leak and lost some of its fluid?
Simply stated, if the oil can leak out past the seal, contaminants in the form of dust, dirt, water and chemicals can enter the lubrication system, causing increased rates of wear through abrasion, scoring of moving parts, adhesion, fatigue and corrosion. Think of a hydraulic cylinder rod extending under pressure.
What causes a hydraulic pump to Cavitate?
The product of excessive vacuum conditions created at the hydraulic pump’s inlet (supply side), cavitation is the formation, and collapse of vapors within a hydraulic pump. High vacuum creates vapor bubbles within the oil, which are carried to the discharge (pressure) side. These bubbles then collapse, thus cavitation.
Can gear pumps Cavitate?
Cavitation damage is caused by the shock waves created when the vapor cavities collapse near the elements in the pump. Cavitation occurs along stationary and moving elements in a pump. For example, the inlet flow hole in a gear pump and the low-pressure side of a gear tooth are places where cavitation could occur.
Why should we avoid cavitation?
The real problem is cavitation, which is caused when bubbles form and implode in pump systems, sending hot streams of water rocketing toward parts that can cause physical damage and render a pump useless. Avoid suction strainers. Suction strainers are intended to prevent hydraulic pumps from ingesting dirt and grime.
What are the signs of cavitation?
What are the symptoms of cavitation? The obvious symptoms of cavitation are noise and vibration. When bubbles of vapour implode they can make a series of bubbling, crackling, sounds as if gravel is rattling around the pump housing or pipework.
What are the methods to avoid cavitation?
How to Prevent Cavitation
- Reduce motor speed (RPMs).
- Install an impeller inducer.
- Incorporate a booster pump into your pump system.
- If possible, reduce the temperature of your pump, liquid, and/or other components.
- Increase liquid level around the suction area.
What are the effects of cavitation?
The effects of cavitation are hydraulic (low efficiency due to flow instability) and mechanical (surface damage, noise and vibration). In addition, it may also lead to surface erosion. It is difficult to avoid cavitation in hydro turbines which cannot be avoided completely but can be reduced.
What happens if a pump is oversized?
An oversized pump can cause excessive noise and vibration of pipes which over time can loosen flanged connections and joints as well as cause fatigue of pipe welds. This can lead to premature wear and failure.
