Roots blower installation procedures and installation methods

 Installation procedure of Roots blower After we choose Roots blower, there will be a confusion, how to install it? 

How to install it correctly?

 Therefore, Xiaobian sorted out the program installation for everyone to read. 

 Install general procedures: Acceptance retest -- pad installation -- base installation -- Speeder installation -- Roots fan installation -- motor installation -- oil station installation -- silencer installation -- pipeline construction -- pipeline pressure test -- test run. 

 1, acceptance retest: the fan to carry out acceptance, check whether the human body damage.  

 2, pad installation: In order to destroy the fan, it is necessary to lay out 2 groups of pads at each footing screw distributed around the block, the installation of pads should meet the weight regulations of the equipment, the appearance should be orderly, no tilt, the exposed equipment base 10-20mm, the upper plane elevation deviation of each pad group is not more than 3mm, each group of pad group, pad and pad, pad and the bottom edge of the equipment contact symmetry.          3, the base installation: the bottom of the fan installation base, the base is stable, tight, firm. 

 4. Installation of the speed increasing machine: Place the speed increasing machine on the good pad, and then level and correct.

 5, Roots fan installation: Lift the fan to its base with the crane, basically tighten the connection bolts between the fan and the base, remove the accessory components on the upper shell of the blower, remove the bearing cover and bearings on the inlet and exhaust side of the fan, remove the connection bolts and positioning pins between the middle split planes, lift the upper shell vertically, remove the connection bolts and positioning nuts between the two sides of the adjustment cylinder, and remove the bolts between the adjustment cylinder and the guide ring. Lift the upper end of the adjusting cylinder and the upper part of the guide ring, remove the connecting bolts and positioning nuts between the two sides of the blade bearing cylinder, lift the upper half of the blade bearing cylinder vertically, loosen the connecting bolts of the fixing plate and the adjusting cylinder support, install the lifting tool, lift the blade bearing cylinder and the lower side of the adjusting cylinder, install the lifting device on both sides of the blade bearing cylinder and the adjusting cylinder assembly, and rotate 180°. Loosen the guide ring, lift the bolts of the lifting device, lift the lower half of the adjustment cylinder and the lower half of the guide ring, the installation process is the opposite, each part must be carefully cleaned before use. 

 After cleaning, the part that should add glycerin or oil needs to be well oil. Before using the adjustment cylinder, the lower shell should be levelled, the flatness of the divided surfaces in the lower shell should be measured, and the top wire of the base should be adjusted to make the four supporting surfaces touch. 

The flatness tolerance of the shell is: vertical 0.04mm/m, horizontal 0.06mm/m. After installing the blade bearing cylinder, install the rotor that has already measured the dynamic balance (the dynamic balance of the rotor is ensured by the manufacturer, the actual lifting and the use of tools refer to the manual operation) and then the disassembly sequence. During use, it is necessary to check whether the clearance of each part meets the corresponding provisions in the manual and certificate according to the random materials (many relevant requirements refer to the manual certificate). During the installation and testing process, the manufacturer and Party A should participate in the corresponding personnel. In case of any problems, it is necessary to negotiate and solve them in time. The coordinate elevation error of the transmission side bearing should not be greater than 0.015mm, the longitudinal center of the lower shell should overlap with the vertical axis of the bearing seat, the tolerance is 0.03mm, the horizontal plane of the left and right shell should be fitted in the free state, when the connection bolts are tightened evenly by 1/3, there should be no gap nearby, pay attention to the radial clearance between the static blade and the rotor, the moving blade and the shell. The end face and axial circular runout of each part of the rotor, the gap between the guide structure on the base and the human body guide groove, these gaps should meet the requirements of the equipment technical documents, and should be recorded accordingly. The blower is a precision manufacturing equipment, the parts should be solved, some parts should be placed on the support, for the surface to facilitate damage, chafed parts should be placed on the rubber pad or wood, in the disassembly to be clearly marked on the non-working surface or do a good job of the corresponding prefix, placed in a clean area by a special person to take care of, according to the instructions of the shaft connecting the shaft. 6, the main motor installation: use the crane to lift the motor to its base, good shaft connector, according to the speed reducer leveling, find the motor, coaxiality, should meet the technical standards, tolerance is ±0.015mm, and then connect the shaft connector, install the cable box. 7, fan auxiliary equipment installation: its auxiliary equipment mainly includes grease station, power oil station, air supply header, muffler, gate valve and the corresponding pipeline, grease station and power oil station due to small vibration, small net weight, low installation accuracy, the use of chisel release pad installation, the oil station is put in place after leveling and straightening, and then grouting. The air supply header, gate valve and pipe should not be installed, the oil pipe should be pickling and oil cleaning, the muffler should be the corresponding basic to find the right, must pay attention to is connected with the blower body inlet and outlet corresponding to the air pipe, the flange and the connected body flange should be the same boat, the two flanges should be balanced, the connection flange should pay attention to avoid the air pipe lifting force on the human body, prohibit opposite. 8. Test run (1) The preparation work before the test operation of the equipment shall, in addition to meeting the requirements and the provisions of the technical documents of the equipment, meet the following conditions: A. Keep the pipes and equipment on the suction side of the blower clean. B. The prime mover that drives the blower must be carried out at the end of the test run according to the requirements of the technical components of the equipment. (2) The test run of the equipment shall comply with the following provisions: a, air filter, dehumidification equipment test run should comply with the equipment technical documents. B. Gate valve test operation should meet the requirements. (3) The stator blade of the blower itself can be adjusted: a, the cylinder piston in the full stroke back and forth 10 times, the action should be flexible, no blocking, the position is correct. b, cylinder piston stroke and speed should meet the requirements of the equipment technical documents. C. The scale on the human body and the viewing Angle indicator on the operating disk should be matched. ⑷ Blower wheel provisions: A. The jacking oil pump works normally. b, clutch chimeric action is flexible and reliable. c, can be manually or automatically completed turning. d. The continuous turning time of the first push blower is 8 hours. e. During the turning up period, the blower and motor should operate normally. (5) Equipment linkage test shall comply with the following provisions: A. Speed up operation and low load operation shall be carried out according to the requirements of the equipment technical documents, and the low load operation time is 4 hours. b, the blower with adjustable stator blade should run smoothly for 4 hours after reaching the rated load. C. When changing the operating state, ensure the operation of the blower's operating area. d, rated load operation after all parts of the abnormal and then reduced to low-load operation, low-load operation time is 1 hour, should be started immediately after shutdown. e, the load operation of the test items and accuracy requirements should meet the requirements of the equipment technical documents. If the Roots blower test operation is normal, it can be used normally, in use, pay attention to the human body.
