The following preparations should be made before starting the blower:
⑴ Fully open the inlet regulating valve, the outlet regulating valve and the bypass pipe;
⑵ Check whether the air filter at the air inlet is unblocked and whether the filter inlet is completely open;
(3) Check whether the support of pipes, valves, mufflers, and air filters is stable. Shaanxi Roots fans must not have a load on the casing;
⑷ Check whether the lubricating oil is good and the model is appropriate. The depth of the lubricating oil layer should reach 3 to 5 cm above the specified oil line, and whether the cooling water system is unblocked;
⑸Push the coupling and check whether the impeller transfer is suitable and whether there is friction collision;
⑹ Check whether the connection of each part is good, the roots fan is supplied, and whether it is loose;
⑺Remove the surrounding debris and keep no debris within two meters of the fan;
⑻ Check whether the electrical parts and press start equipment are intact;
⑼ Check whether the maintenance tools are complete, the Roots fan manufacturer, and whether the fire extinguishing equipment is adequate.
Roots fan standard accessories
Standard accessories: General Roots fan operating procedure base, inlet muffler (including air filter), outlet muffler, safety valve, check valve, elastic joint, pressure gauge, lubricant, anchor bolt. The consumable parts are imported, and the performance is stable. Such as: Japan NSK bearings, South Korea Dongyi belt. 2. The fan impeller is corrected by dynamic balance. 3. The gear is made of 20CrMnTi, and the precision reaches GB / T10095 five-level accuracy. 4. The shaft is 45 # steel after quenching and tempering. 5. Fan noise at 1m is less than 85dB. 6. The company has obtained ISO9001 quality management system certification, and there is a strict testing procedure before the fan leaves the factory. The gap between the two impellers is the key clearance between the two impellers, and there are two + 45 ° and two -45 ° positions. (When adjusting and measuring the gap, you can determine whether the two impellers are at a position of 45 °).
Check during operation:
(1) Adjust the air inlet valve of the contact oxidation tank to make it evenly aerated;
(2) Dissolved oxygen is controlled at 2 ～ 4mg / L (read through dissolved oxygen meter).
(3) In the early period of operation, due to the viscosity of the lubricating oil, there may be noise and excessive current. Roots fan prices can disappear by themselves after 10 to 20 minutes of operation.
(4) The flow cannot be adjusted by opening and closing the valve. The fan is a volumetric compressor, which changes the flow rate and shaft power by adjusting the speed;
(5) The pressure gauge switch is in the normally closed state. If you need to measure the pressure, you can turn the pressure gauge switch on.
(6) The noise of the same model is also different, because the position of the fan in the machine room and the piping situation will cause differences in noise.
