Preparation of Roots Blower before use
Roots BlowerBefore the use of those preparations is that we must understand, on this issue Roots blower small make up to take you to understand.
(1) Check the installation quality of fasteners and locating pins.
(2) Check the installation quality of the inlet and outlet pipes and valves.
(3) Check whether the assembly clearance of the Roots blower meets the requirements.
(4) Check that the coaxiality of the fan with the motor and drive shaft shall not exceed 0.1 mm, otherwise it will cause fan vibration and oil leakage, affecting the service life of the fan.
(5) Check that all parts around the base of the unit are secure and that the ground bolts are tight.
(6) Before starting the Roots fan, the main and auxiliary oil tanks should be lubricated to 3 mm/2 mm at the center of the oil mark. The lubricating oil used is 68 oil in summer and 100 oil in winter. Replace the lubricating oil every three months.
(7) The upper and lower oil plugs of the main and auxiliary tanks should be tightened due to the presence of pressure in the main and auxiliary tanks, otherwise oil leakage will occur.
(8) Cooling section water flow. The temperature of the cooling water shall not exceed 25°C, and the flow rate of the cooling water shall be 10 L/m inch.
(9) Open the fan inlet and outlet valves, drive the rotor to move, pay attention to the abnormal noise of each component.
(10) Check the steering of the motor; the steering must conform to the direction indicated by the steering sign. Otherwise, the fan will not exhaust properly and the blades may collide. When water expands, water will flow into the fan in the opposite direction. The extractor fan caused the accident.
