Thickness of Stuffing Box Body Solution

STEP 0: Pre-Calculation Summary

Formula Used

Thickness of Stuffing Box Body = (Design Pressure of Stuffing Box*Internal Diameter Stuffing Box)/(2*Allowable Stress for the Stuffing Box Material)+6
t = (p*d_sb)/(2*f)+6
This formula uses 4 Variables

Variables Used

Thickness of Stuffing Box Body - (Measured in Millimeter) - Thickness of Stuffing Box Body that is slightly bigger than the prop shaft it will also have packing nut threads or a gland nut.
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 Millimeter) - 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.
Allowable Stress for the Stuffing Box Material - (Measured in Pascal) - Allowable Stress for the Stuffing Box Material is defined as the material failure stress (a property of the material) divided by a factor of safety greater than one.

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 --> 70 Millimeter No Conversion Required
Allowable Stress for the Stuffing Box Material: 102 Newton per Square Millimeter --> 102000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t = (p*d_sb)/(2*f)+6 --> (300000*70)/(2*102000000)+6

Evaluating ... ...

t = 6.10294117647059

STEP 3: Convert Result to Output's Unit

0.00610294117647059 Meter -->6.10294117647059 Millimeter (Check conversion here)

FINAL ANSWER

6.10294117647059 ≈ 6.102941 Millimeter <-- Thickness of Stuffing Box Body

(Calculation completed in 00.020 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

What is Stuffing Box?

A stuffing box of a sailing boat will have a stern tube that is slightly bigger than the prop shaft. It will also have packing nut threads or a gland nut. The packing is inside the gland nut and creates the seal. The shaft is wrapped by the packing and put in the gland nut. Through tightening it onto the stern tube, the packing is compressed, creating a seal against the shaft. Creating a proper plunger alignment is critical for correct flow and a long wear life. Stuffing box components are of stainless steel, brass or other application-specific materials. Compression packing is rigorously tested to ensure effective sealing in valves, pumps, agitators, and other rotary equipment.

How to Calculate Thickness of Stuffing Box Body?
