These costs add up! Equation for calculating the force of the double action hydraulic cylinder in the reverse motion: F = p (D 2 -d 2 )/4. How long your hydraulic hose will actually keep its condition, however, depends on a number of variable factors, many of which are within your control. The additional costs incurred on its repairs renders a lot more cost than the entire hose replacement. Steps for Hydraulic calculation. Choose hose type then choose size from the drop down menu. hydraulic hose Sizing Nomogram Use the nomogram below to determine Hose ID Size based on Flow (Q) and Velocity. Consider your correct hose I.D., desired flow rate, and recommended flow velocity. of 6/16" - or 3/8". Example: Calculate the pressure acting on a diver in the ocean at the depth of 15 m. The density of ocean water is 1022 kg/m and the atmospheric pressure is 101325 Pa. Fluid Density. In most industrial applications (such as water or general purpose) the OAL is not critical, but in many hydraulic applications, the OAL can be critical due to space restrictions. Now, let's calculate the hose sizes: Supply (Pressure) Hose The hose cut length for a hose assembly is calculated by subtracting the cut-off factor (distance from the bottom of the ferrule or collar to the end of the fitting or . The ideal storage conditions for hose is indoors in a dark, dry atmosphere away from any heat or electrical sources. If you still have questions contact us for further assistance. The formula for calculating the hose size is as follows: V = Q / (3.117 * pi/4 * D ^ 2) or D = (Q / (3.117 * pi/4 * V) ) ^ 1/2. By combining cutting-edge technology with comprehensive industry expertise, our calculators make your complex operational tasks and decisions simple. Use quality hoses for replacements. ABOUT US.

Our handy Drum Capacity Calculator is an easy to use tool which calculates how much hose or tube can be spooled onto a drum or reel of a given size. Enter the GPM and PSI (pressure) to calculate Horsepower. 1. Exposure of wire within the hose, which means the strength of the hose may have been compromised. Look for tight bends, twisting, abrasions in hose covers, cuts, exposed wires, or cracks. Intersection on the third vertical . The LifeSense hose condition monitoring system is a revolutionary monitoring system that detects impending hydraulic hose failure and alerts operators and maintenance crews so they can schedule maintenance and plan downtime. Q - volumetric flow rate, m 3 /s, A - pipe's cross-sectional area, m 2, A=d 2 /4, d - pipe bore, m. Reynolds number Re. Note: The sizing guidelines say to always round up. If you are using a lower quality hose, that can be even sooner. Our hoses range in size from 3/16" to 3" I.D. Factors such as operating conditions, ambient temperature, pressure, and the type of hydraulic fluid all play a role in how long a spiral hydraulic hose survives in service. of a hydraulic hose or fitting in 1/16" increments. 2. PRESSURE PIPE: From 3,5 to 5 m/sec for Pressure up to 150 Bar. In the example below, take special note of Dimension "B."

Hose Assemblies 3/8 JIC; Hose Assemblies 3/8 NPT; Hose . . Keep the temperature between +10 C to +20 C. Remember, any hydraulic hose system kept for a length of time needs inspecting for cracks, leakage and the couplings inspected then tested before use. Hoses are designed for specific flow rates, pressures and temperatures. Specific hose information is displayed throughout Catalog 4400, Section A. LIVE LENGTH CALCULATOR. In order to start calculating hydraulic hose dimensions, you need to know the following parameters. The Parker Tube Fittings division has created a calculator to determine estimated costs associated with leakage. A hydraulic fluid leak of one drop per second translates into 420 U.S. gallons (1,600 L) lost per year. Pressure p: Units Pa Pascal kPa KiloPascal MPa MegaPascal Bar Bar psi Pound-force per square inch at Technical atmosphere. Marked OD on the picture. Flow rate Q is defined to be the volume of hydraulic fluid passing by through a hydraulic hose during a period of time. As it pushes the collar, the collar compresses the die. 2. Turn on the machine.

Length of Bent Section (yellow) = 1/4 x 2R (334) = 1/4 x 2 x 3.142 x 334 = 525mm. The inner tube needs to be compatible with the fluid it is carrying and requires some flexibility. This calculator will help you choose the correct part number for the hose that you are looking for. Please take a moment and review. People new to the hydraulic industry often ask what hose dash size means. Disclaimer. . Target operating temperatures should be between 104F and 120F. If we deviate from their specifications, hose life can suffer. Piston diameter D: Length of top, Straight Section, including the top end fitting length = 600 - 334 . Where: V is fluid velocity in ft/sec Q is fluid volume in gallons/min D is hose inside diameter in inches. I am old-fashioned - I prefer good old nomograms and a ruler to calculators and specialized software - a harmless tribute to tradition, if you will, like using an analogue pressure gauge over a digital one - simple and . If a customer needs a hose that can bend at 90 and has a bend radius of three inches, then the minimum length of the hose would equal: 45/360 x 2 (3.13) (3) = 2,3475 inches. Run the numbers and potential loss for your operation factoring in things such as drops per minute, time of operation, cost of oil and more. As a fluid is forced from one point to another, certain forces act on the fluid that cause it to lose and in one case (the case of elevation) potentially gain pressure. In 2005, we made a substantial investment into thermoplastic hose manufacturing. Viscosities are only accurate between 100F and 212F. Hydraulic (8,825 Items) Crimpers/Tooling (527) Hydraulic Accessories (220) Hydraulic Adapters (2,316) Hydraulic Assortments/Kits (55) Hydraulic End Fittings (3,709) Hydraulic Hose Miscellaneous (27) Hydraulic Hose Rubber (333) Hydraulic Hose Thermoplastic (49) Hydraulic Quick Disconnects (680) O-Rings (909) The reinforcement layer consists of one or more sheaths of fabric, braided wire or spiral-wound wire. A hydraulic hose consists of at least three parts, and inner tube that carries the fluid, a reinforcement layer and a protective outer layer. Highly pressurized hydraulic systems quickly break down if something's wrong. If you know any of these two values, you can determine the third using the nomograph chart below. It is 10 years. More. Costs associated with hydraulic oil loss and clean-up are two more unplanned cost centers attributable to reactive hose assembly replacement.
