Horsepower of the Screw-like airlock valve
By referring to the catalog of the Conveyor Engineering & Manufacturing: SCREW
CONVEYOR COMPONENTS AND DESIGN. We are able to obtain the equation to
calculate the Horsepower needed to drive the screw.
Title: Mass Moment of Inertia
Objective: To determine mass moment of inertia of a part using experimental method.
If a part has been designed and built, its mass moment of inertia can be determined
approximately by a simple experiment. This requir
This assignment contains three (3) questions and you are required to answer all the
questions. This assignment will contribute to 10% of the course work marks. The
assignment must be word processed (e.g. MS Word). Please this page as front cove
Experiment 2: Construction of a program for a simple traffic light system using counter
and time functions of a PLC
Learn the PLC timer and counter command instructions.
To design a simple traffic light system.
Equipment and Materials
It is a mechanical device that is frequently used to enable rotational or linear movement of shaft.
In our project, it is used to only allow smooth rotational motion of shaft (rotor). It helps reduce
friction between the surface of the bearing and
Procedure of Assembly
Housing (BottomScrew plate)
Firstly, the bottom part of the airlocks housing is make up by the section or component
shown in Figure 1. Where each of the components wil
Function of components
The rotor is in vertical screw shape. The function of the rotor is transfer or discharge the fly ash
from cyclone to dust collector. The screw shape is to ensure that the ash will slide down when the
rotor is rotating or stop
Initial Input data:
Application: Screw Conveyor
Type of driver: Electric motor
Load type: Moderate shock (heavy conveyors)
From table 7-8,
Service factor for the chain drive is chosen as 1.4.
Power input = 0.06kW
1 Tolerance and fits
A Tolerance and fits in Bearings:
For the Tolerance and Fits in bearings, FN1(light drive fit) is chosen because the
bearing and shaft is constantly in contact of high temperature of the fly ash, and light
pressure and no large force
