【正文】 ? This is not an English course. It is a course to use English to understand the speciality. ? Testing is a way to check your understanding for the course. ? Encourage students to join us to build a testing database for testing. ? To choose the best questions, and best answers, to help you understanding the course. ? 答疑及課外輔導(dǎo)時(shí)間： 21 Process Industry The Process industry is posed of refineries and petrochemical, paper and pulp, power generation, and food processing plants. 22 Process Industry Process technicians inspect and maintain equipment , place and remove equipment from service, plete checklists, control documentation, respond to emergencies, and troubleshoot system problems. 23 Process Industry To fulfill those responsibilities, the process technician must have a through understanding of tools, equipment, and systems. 24 Basic Hand Tools 25 1. Rotary Equipment Process Equipment can be divided into: 2. Stationary Equipment 26 1. Rotary Equipment Safety Notice: Severe injuries can result when loose clothing, shoelaces, jewelry, or long hair gets tangled around rotating parts. Tips: aware of protecting your self to avoid any injuries, especially for your eyes. ?

Rotary Equipment Drivers and Equipment A driver is a device designed to provide rotational energy to another piece of equipment. The most mon driver Pumps Compressors Generators Fans Conveyors Solid feeders Couplings, belts, or chains connect drives and driven equipments. ? 28 1. Rotary Equipment Drivers and Equipment Couplings Fixedspeed couplings Rigid couplings Flexible coupling Variablespeed couplings Hydraulic couplings Magic couplings ? 29 1. Rotary Equipment Drivers and Equipment Belts are used to connect two parallel shafts. ? A pulley is mounted on the end of each shaft. ? The size of the pulleys allow the driver and driven equipment to operate at different speeds. ? Belts fit in the grooves of the pulley. ? Belts e in a variety of shapes and sizes and are made of durable material designed to withstand operating conditions. ? 30 1. Rotary Equipment Drivers and Equipment Belts are used to connect two parallel shafts. ? Belt drives require less space than fixedspeed or variablespeed couplings. ? A belt drive can make speedtotorque or torquetospeed conversions. ? Process technicians frequently inspect belts during rounds to ensure that safety guards are in place, that belt tension is correct, and that the belts are still mounted on the pulleys. ? Flopping, squealing, or smoking belts indicate wear, tension, or drivenequipment problems. ? 31 1. Rotary Equipment Gearboxes and Power Transmission ? Often used between the driver and the driven equipment. ? The drive gear meshes with a larger or smaller gear, the driven gear. ? As the drive gear rotates, the interlocked gears in the box turn, transmitting power to the driven equipment. ? Small gear size is associated with speed. Large gear size is associated with torque. ? 32 1. Rotary Equipment Gearboxes and Power Transmission ? Power transmission in rotating equipment is classified as speedtotorque conversion or torquetospeed conversion. ? Speedtotorque conversion is acplished with a small drive gear with a large driven gear. ? Torquetospeed conversion uses a large drive gear with a small driven gear. ? 33 1. Rotary Equipment Electric motors The process industry uses electric motors to operate pumps, generators, pressors,
