Load on Gland Solution

STEP 0: Pre-Calculation Summary

Formula Used

Load by Gland = (pi/4)*Design Pressure of Stuffing Box*(Internal Diameter Stuffing Box^(2)-Diameter of Shaft^(2))
F_Gland = (pi/4)*p*(d_sb^(2)-d_shaft^(2))
This formula uses 1 Constants, 4 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Load by Gland - (Measured in Newton) - Load by Gland is the term applied when some form of spring energization is included in the gland bolting system.
Design Pressure of Stuffing Box - (Measured in Pascal) - Design Pressure of Stuffing Box is the stress imposed on an equipment's internal and external pressure that the equipment seems to sustain.
Internal Diameter Stuffing Box - (Measured in Meter) - Internal Diameter Stuffing Box to determine the correct packing size, measure the diameter of the shaft (inside the stuffing box area if possible) and then measure the diameter of the stuffing box.
Diameter of Shaft - (Measured in Meter) - Diameter of Shaft is defined as the diameter of the hole in the iron laminations that contains the shaft.

STEP 1: Convert Input(s) to Base Unit

Design Pressure of Stuffing Box: 0.3 Newton per Square Millimeter --> 300000 Pascal (Check conversion here)
Internal Diameter Stuffing Box: 70 Millimeter --> 0.07 Meter (Check conversion here)
Diameter of Shaft: 12 Millimeter --> 0.012 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_Gland = (pi/4)*p*(d_sb^(2)-d_shaft^(2)) --> (pi/4)*300000*(0.07^(2)-0.012^(2))

Evaluating ... ...

F_Gland = 1120.60609953548

STEP 3: Convert Result to Output's Unit

1120.60609953548 Newton --> No Conversion Required

FINAL ANSWER

1120.60609953548 ≈ 1120.606 Newton <-- Load by Gland

(Calculation completed in 00.008 seconds)

Thickness of Stuffing Box Body

LaTeX Go Thickness of Stuffing Box Body = (Design Pressure of Stuffing Box*Internal Diameter Stuffing Box)/(2*Allowable Stress for the Stuffing Box Material)+6

Internal Diameter of Stuffing Box

LaTeX Go Internal Diameter Stuffing Box = Diameter of Shaft+2*Clearance between Shaft and Stuffing Box

Clearance between Shaft and Stuffing Box if Shaft Diameter is less than equal to 100mm

LaTeX Go Clearance between Shaft and Stuffing Box = 0.2*Diameter of Shaft+5

Thickness of Gland Flange

LaTeX Go Thickness of Gland Flange = (Diameter of Shaft/8)+12.5

Load on Gland Formula

LaTeX Go

Load by Gland = (pi/4)*Design Pressure of Stuffing Box*(Internal Diameter Stuffing Box^(2)-Diameter of Shaft^(2))
F_Gland = (pi/4)*p*(d_sb^(2)-d_shaft^(2))

What is Load?

A standard load-holding valve has been placed between the line running from the directional valve to the rod end of the cylinder. Although known by many different names, a standard load-holding valve can be described as a pilot-assisted relief valve with a free-flow check.

How to Calculate Load on Gland?

Load on Gland calculator uses Load by Gland = (pi/4)*Design Pressure of Stuffing Box*(Internal Diameter Stuffing Box^(2)-Diameter of Shaft^(2)) to calculate the Load by Gland, Load on Gland is used to seal a rotating or reciprocating shaft against a fluid. The most common example is in the head of a tap (faucet) where the gland is usually packed with string which has been soaked in tallow or similar grease. Load by Gland is denoted by F_Gland symbol.

How to calculate Load on Gland using this online calculator? To use this online calculator for Load on Gland, enter Design Pressure of Stuffing Box (p), Internal Diameter Stuffing Box (d_sb) & Diameter of Shaft (d_shaft) and hit the calculate button. Here is how the Load on Gland calculation can be explained with given input values -> 1120.606 = (pi/4)*300000*(0.07^(2)-0.012^(2)).

FAQ

What is Load on Gland?

Load on Gland is used to seal a rotating or reciprocating shaft against a fluid. The most common example is in the head of a tap (faucet) where the gland is usually packed with string which has been soaked in tallow or similar grease and is represented as F_Gland = (pi/4)*p*(d_sb^(2)-d_shaft^(2)) or Load by Gland = (pi/4)*Design Pressure of Stuffing Box*(Internal Diameter Stuffing Box^(2)-Diameter of Shaft^(2)). Design Pressure of Stuffing Box is the stress imposed on an equipment's internal and external pressure that the equipment seems to sustain, Internal Diameter Stuffing Box to determine the correct packing size, measure the diameter of the shaft (inside the stuffing box area if possible) and then measure the diameter of the stuffing box & Diameter of Shaft is defined as the diameter of the hole in the iron laminations that contains the shaft.

How to calculate Load on Gland?

Load on Gland is used to seal a rotating or reciprocating shaft against a fluid. The most common example is in the head of a tap (faucet) where the gland is usually packed with string which has been soaked in tallow or similar grease is calculated using Load by Gland = (pi/4)*Design Pressure of Stuffing Box*(Internal Diameter Stuffing Box^(2)-Diameter of Shaft^(2)). To calculate Load on Gland, you need Design Pressure of Stuffing Box (p), Internal Diameter Stuffing Box (d_sb) & Diameter of Shaft (d_shaft).
