Servo Valve || Electro Hydraulic Servo Valve (EHSV)

Servo Valve || Electro Hydraulic Servo Valve (EHSV)
In this video i explained symbols ,construction , working, stages and difference between proportional valve and servo valve.
A servo directional control valve integrates feedback mechanisms to precisely regulate fluid flow in response to external commands or system parameters. It maintains accurate positioning and movement control, crucial for demanding applications like robotics, aerospace, and precision machining. By leveraging closed-loop control systems, it ensures consistent performance under varying loads and conditions, enhancing operational efficiency and safety. This valve type optimizes responsiveness, minimizes errors, and supports complex automation tasks, making it indispensable where precise motion control and reliable operation are paramount. Its design excellence underscores its role in advancing technology-driven industries with unparalleled accuracy and performance capabilities.

Good morning Nice video sir Sir system mein jab multiple cylinder ho to LPM kese nikale Plz help

[@JPhydrauliccircuit]

First of all thank you brother video ko like and comment krne ke liye. Or multiple cylinder ka jb LPM nikana he to us ke liye kuch formulas hai wo me bta deta hu or ek example solve kr ke bhi de deta hu us calculation me aap apne system ke value ya number dal ke calculate kr skte ho

1. Number and Size of Cylinders : Determine how many cylinders are in the system and their individual bore (diameter) and stroke (length of travel). The bore determines the piston area (A) and stroke determines the volume of fluid required per cylinder per cycle. 2. Cycle Time : Understand the cycle time or speed at which you want each cylinder to extend and retract. This will affect the flow rate required. 3. Flow Requirements : Calculate the total volume of fluid needed per unit of time based on the cylinder movements. Each cylinder will have both extension and retraction phases, and you'll need to account for both. Here’s a step-by-step approach to calculate the LPM flow rate: Step 1: Calculate the Volume Requirement for Each Cylinder Volume per Stroke (V_stroke) : Calculate the volume of fluid required for one stroke of each cylinder. V stroke = A × S Where: ( A ) = Area of the cylinder piston (π * (bore/2)^2) ( S ) = Stroke length Step 2: Determine the Cycle Time Cycle Time (T) : Determine how fast you want each cylinder to move (in seconds per cycle). This will depend on your application and desired speed. Step 3: Calculate Flow Rate for Each Cylinder Flow Rate per Cylinder : Calculate the flow rate required for each cylinder to achieve the desired speed. Q cylinder = Vstroke ÷ T Step 4: Total Flow Rate for Multiple Cylinders Total Flow Rate (Q_total) : Sum up the flow rates required for all cylinders in the system to get the total LPM required. Q total = Qcylinder1 + Qcylinder2+Qcylinder.... Step 5 : Consider Safety Margin and System Efficiency Safety Margin : It's often wise to add a safety margin (typically 10-20%) to account for variations in system performance, pressure drops, or future expansion. Q total = Q total × (1 + safety margin) Step 6: Select a Hydraulic Pump Pump Selection : Once you have the total flow rate required, select a hydraulic pump that can provide at least this flow rate at the required pressure. Example Calculation: Let's say you have: - 3 cylinders with bore diameter ( D ) = 100 mm bore radius ( r ) = 50 mm - Stroke length ( S ) = 500 mm - Cycle time ( T ) = 10 seconds 1. Calculate piston area ( A ): A = π r^2 = π (0.05)^2 = 0.00785 m^2 2. Calculate volume per stroke V stroke : Vstroke = A× S = 0.00785 m^2 × 0.5 m = 0.003925 m^3 3. Calculate flow rate per cylinder Q cylinder : Q cylinder = V stroke ÷ T = 0.003925 m^3 ÷ 10 s = 0.0003925 m^3/s 4. Total flow rate Q total for 3 cylinders: Q total = 3 × 0.0003925 m^3 / s = 0.0011775 m^3/s 5. Convert to liters per minute (LPM): Q total = 0.0011775 m^3/s ×60 s/min 1000 L/m^3 = 70.65 LPM Therefore, the total flow rate required for this hydraulic system with three cylinders, given the parameters above, is approximately 70.65 LPM. Adjust the calculations based on the specific parameters of your hydraulic cylinders and operational requirements to accurately determine the required flow rate for your system.
