Chongqing Roots Fan-Jin Blower (Recommended Business)-Large Roots Fan:Tianjin fan , Tianjin blower , Tianjin fan
Check during startup:
(1) If the fan is required to run “power frequency”, you only need to set the corresponding blower switch on the electric control box to “power frequency” and then press the “start” button. The switches and inverters of other fans The switch is turned to "Stop". Note that before pressing the "Start" button, you must check whether the outlet valve of the running fan is open, and whether the fan that is pressed by the "Start" button is consistent with the actual running fan.
(2) If the fan is required to run "Frequency conversion", turn the switch of the inverter down to the "Start" button, and then set the corresponding blower switch on the electric control box to the "Frequency conversion" position. The switch of the fan is in "stop". Before setting the switch to the "frequency conversion" position, be sure to check whether the outlet valve of the running fan is open, and whether the fan pressed by the "frequency conversion" button is consistent with the actual fan.
(3) After the fan runs normally (it usually takes 1 minute), then close the exhaust valve slowly, so as not to cause the instantaneous current of the fan to burn out the motor due to excessive shutdown.

5. The overload of the blower is sometimes not displayed immediately, so pay attention to the increasing trend of intake and exhaust pressure, bearing temperature and motor current to determine whether the machine is operating normally. 6. Before disassembling the machine, measure the dimensions of each machine's fit, make a record, and mark the parts to ensure that the original fit requirements are maintained after assembly.
7. The blower of the new machine or overhaul, Chongqing Roots blower, the fuel tank should be cleaned and put into operation according to the use steps. Roots blower is supplied. It is recommended to replace all the lubricating oil after 8 hours of operation.

2. The content of particles in the medium must not exceed 100mg / m3, and the size of the particles must not exceed half of the working gap.
3. The bearing temperature during operation must not be higher than 95 ℃, and the temperature of lubricating oil should not be higher than 65 ℃.
4. The operating pressure should not be higher than the boost range specified on the nameplate.
5. The clearance between the impeller and the casing, the impeller and the side plate, and the impeller and the impeller of the Roots blower have been adjusted at the factory, and the clearance must be ensured when reassembling.
6. When the Roots blower is running, the oil level of the main tank and auxiliary tank must be between the two red lines of the oil level gauge.
