During the use of the three blade roots blower, the setting and adjustment of the hydraulic valve parameter value is a common problem. According to the different protection containers and pipelines, the parameter value of the relief valve should also be adjusted at any time, so that the roots blower equipment can operate safely and stably.
Setting method of air release valve of three blade roots blower:
When starting the three blade roots blower, while observing the pressure gauge, tighten the gate valve to make the pressure gauge greater than the set value by about 10%. Loosen the lock nut and rotate the adjusting screw counterclockwise until air is discharged from the safety valve. If the set pressure is not reached during the process of tightening the gate valve, the safety valve has discharged air.
Rotate the adjusting screw clockwise again until it is not at the air discharge position, and rotate counterclockwise until the air is just discharged (clockwise, the set pressure becomes higher; counterclockwise, set
The constant pressure decreases), tighten the lock nut and adjust the screw rod. Loosen the gate valve, reduce the pressure, so that the vent valve is not venting, check whether the vent valve works under the set pressure, and tighten the gate valve again to increase the pressure.
Maintenance and installation method of fasteners and locating pins of three blade roots blower:
1. Check the installation quality of fasteners and locating pins.
2. Check the installation quality of inlet and outlet pipes and valves.
3. Inspection Trefoil Whether the assembly clearance of Roots blower meets the requirements.
4. Check that the coaxiality of fan, motor and drive shaft shall not exceed 0.1mm, otherwise it will cause fan vibration and oil leakage and affect the service life of fan.
5. Check whether all parts around the equipment base are firm and whether the foundation bolts are fastened.
6. Trefoil Before starting roots blower, the main oil tank and auxiliary oil tank shall be lubricated to 3mm/2mm at the center of oil mark. The lubricating oil used is 68 engine oil in summer and 100 engine oil in winter. Replace the lubricating oil every three months.
7. Since there is pressure in the main oil tank and auxiliary oil tank, tighten the upper and lower oil plugs of the main oil tank and auxiliary oil tank, or oil leakage will occur.
8. Cooling water flow. The cooling water temperature shall not exceed 25 ° C, and the cooling water flow shall be 10L/m inch.
9. Open the inlet and outlet valves of the fan, drive the rotor to move, and pay attention to the abnormal noise of each component.
10. Check the rotation direction of the motor, which must conform to the direction indicated by the direction sign. Otherwise, the fan cannot exhaust normally, and the blades may collide. When the water expands, it will flow into the fan in the opposite direction.
I believe that after reading the above content, you should also Trefoil I have understood the setting method of the vent valve of Roots blower. I hope it will be helpful to everyone.
