Page 4: Chapter One： Safty Attention
BALDOR AIR COMPRESSOR Chapter One：Safety Attention Read it carefully before operating the air compressor safely 1. Before install the piping welding, move the near flammable items and prevent welding spark dropping into the air compressor. The power of the air compressor supplying line must be matched with air switch, fuse and the other safety device. -
Page 5: Chapter Two：installation Standards And Requirements
BALDOR AIR COMPRESSOR Air compressor should be operated by permanent staff. Operator should read through and understand the contents of this manual, following the instructions of the working procedures, safety precautions and maintenance instructions. The compressor can not be directly used as produce breathing equipment, if you want to achieve breathing standard, compressor should do corresponding purification treatment. -
Page 6: B 、Installation Environment Layout Requirements
BALDOR AIR COMPRESSOR b、 INSTALLATION ENVIRONMENT LAYOUT REQUIREMENTS 1. Machine room should be close to the load centre, so as to shorten the length of pipe, reduce the pressure loss & power consumption, and guarantee the air supply pressure. 2. Consider the rationality of the power supply, water supply when planning the room position. -
Page 7: C、Installation Proposals
BALDOR AIR COMPRESSOR 1. Due to the large heat release of the compressor, especially in summer, the inner temperature is high, so the machine room should be well ventilated and less sunlight. 2. Though there is a case outside the air compressor, it is strictly prohibited from rain and sunlight. -
Page 8: D、Installation Requirements
BALDOR AIR COMPRESSOR d、INSTALLATION REQUIREMENTS 1. Leave enough room for repairing and maintaining the air compressors. 2. The ground is best to be smooth cement floor. The air compressor base should be placed at the concrete platform above the ground 150 mm high, and platform levelness is not more than 0.5/1000 (mm). -
Page 9: E、The Confirmation Of Air Supply Scheme
BALDOR AIR COMPRESSOR e、THE CONFIRMATION OF AIR SUPPLY SCHEME According to the workshop size, air distribution, the air supply pressure level, air quality grade and other factors, we confirm several air supply plans by comprehensive consideration and technical & economic comparison. -

BALDOR AIR COMPRESSOR f、 THE CONFIRMATION OF AIR CAPACITY 1. Calculate the air capacity according to the sum of average consumption Q ：air capacity Q ： :sum air compressor or workshop average consumption Consumption inequality (maximum) coefficient 1.2-1.4... -
Page 11: A、A Irend Structure And Working Principle
BALDOR AIR COMPRESSOR 3. Calculate the air capacity according to comprehensive situation Q ： the maximum consumption of the main using air equipment Q ： the average consumption of other using air equipment This method can be used for the individual high air consumption equipment. - Page 12 BALDOR AIR COMPRESSOR 2、working principle Working cycle can be divided into three processes: suction, compression and exhaust. 2.1 suction process As shown in picture a (screw compressor suction process), the pair of gear is arrowed. Male rotor rotate clockwise and female rotor anti-clockwise. As in the picture a, the rotor end is for exhaustion. When the rotor rotates, the gear meshing with each other in the inlet end gradually disconnect, thus the composition of the gear space volume increase gradually, and it connects with the air inlet, beginning to breathe in.

Page 14: Chapter Four：electrical Control System And Circuit
BALDOR AIR COMPRESSOR cooling system process Screw air compressor is divided into air cooling type and water cooling type, through the fan or water forcing cooling. Air cooling system consists of cooling fan, oil coolers and air cooler. The cooled air is pumped into the fan;... -
Page 15: B、Control System Function
(If the local regulation is stricter than the above requirements, follow the provisions of the local. b、Control system function A series of BALDOR air compressor 1、start machine When switch on, first, observe whether the power is in phase inversion. The machine has phase sequence protection. - Page 16 BALDOR AIR COMPRESSOR main engine air inlet. Thus, only little air can go into the main engine to ensure the system lubricating oil pressure. At the same time, the relief valve in the electromagnetic valve or inlet valve automatically opens, lowering the air pressure in oil-air separator, making the system run with no-load.

Page 20: Chapter Five:pipe Line Configuration And Installation
BALDOR AIR COMPRESSOR Chapter Five: Pipeline Configuration And Installation a. pipeline installing requirements The machine air-supply port with screw thread adapter can connect with air-supply pipeline. Please refer to the product appearance size when install. When checking and maintenance, in order not to affect the overall or other machines work and prevent air from flowing back, the stop valve should be installed between the machine and the storage tank, and safety valve should be installed in the air storage tank. - Page 21 BALDOR AIR COMPRESSOR supply air by special line or install storage tank near the air compressor to relieve the load, making the pressure stable. the selection of pipeline size There is friction resistance in the pipe line and resistance is produced in the valve, joint, bend and the...

Page 23: Chapter Six: Operational Guidelines
BALDOR AIR COMPRESSOR the connection and arrangement of air pipeline 1、 Generally should use welding connect the air pipeline, but should use the corresponding flange or screw threaded connection in the joint of equipment and valve. The section which is often removed, should use screw threaded connection when the pipe diameter is less than or equal to DN25, and use flange connection when more than DN25. - Page 24 BALDOR AIR COMPRESSOR 5、 If test the machine after delivery a long time later, should add 0.5 liters of lubricating oil to the inlet and rotate several turns manually or move a few times, in order to prevent the compressor start to burning without oil. Please pay attention not to let other objects fall into the machine body or else will damage to the compressor.
