Aiming at the corrosion problem of Roots fans, Roots fans manufacturing and replacement of equipment components are generally adopted by enterprises, but the equipment is affected by material and processing technology, etc., and is generally of high value, such as glass lined equipment, PTFE components, titanium Materials such as high-value metal materials.
The use of polymer composite materials to implement surface organic coating corrosion protection is one of the effective anti-corrosion measures. At present, the well-established domestic Blessing Blue series. Surface adhesive coating protection can be widely used in the repair of abrasive, cavitation and corrosion parts and pre-protective coatings. It has good chemical resistance, excellent mechanical properties and adhesive properties. Compared with traditional pressure vessel welding repair, It has the characteristics of simple construction, low cost, safety performance and good repair effect.
Adjustment of Roots Blower in Tianjin Blower General Plant
Roots blower is mainly composed of the body and two rotors with 8-shaped impellers for operation. Sichuan Roots blower, through the action of a pair of synchronous gears, Roots blower makes the two rotors rotate at the same speed in opposite directions. Relying on the gap between the impeller and the impeller, and between the impeller and the body, the Roots fan brand basically isolates the suction cavity and the exhaust cavity. With the rotation of the impeller, the gas in the volume of the body is pushed to achieve the purpose of blowing air. How to adjust and ensure that the gap between the impeller and the impeller, the rotor and the body reaches the specified range has become the focus of maintenance. Check the equipment maintenance and inspection data. Only the adjusted gap value is required, and there is no specific method for adjusting the gap. 1. L41 × 49WD-1 Roots blower with 45 ° adjustment method, the static theoretical value of the clearance between each part at 20 ° C is: the gap between the impeller and the impeller is 0.4- ~ 0.5mm, and the radial direction between the impeller and the blade shell The clearance is 0.2 ~ 0.3mm, the axial clearance between the impeller and the left and right wall panels is 0.3 ~ 0.4mm (the left wall panel gap must be greater than the right wall panel gap by more than 0.05mm), and the meshing gap of the synchronous gear is 0.08 ~ 0.16mm. The adjustment of the working gap of the fan is the most critical and difficult to master step in the entire maintenance process of the Roots fan. Carefully study the principle of the electronic belt scale structure of the Roots fan, and analyze the impeller during a rotation of 45 °. Position.
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. Note that the switches of other fans are in the "Frequency conversion" position. Stop ", before turning 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 running 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.
