Precautions for installing Roots blowers
For the installation of Roots blowers, please refer to the general mechanical equipment installation specifications. The axis deviation is not greater than ., and the axis skew angle is not greater than r. In addition, the following points need to be noted:
The anchor bolt holes adopt the secondary grouting method. The cross-sectional dimensions and depth of the reserved holes are shown in the outline installation drawing.
The foundation surface on which the unit is installed should be cast into a convex surface and be flat. According to the direction of the inlet and exhaust ports and maintenance needs, sufficient distance should be left around the foundation surface (the distance from the edge of the fan base to the edge of the foundation should not be less than).
During installation, first check the body and confirm that there is no debris, then close the inlet and outlet, thoroughly remove rust, welding slag and other debris in the pipe, and then connect it to the fan. It is required that the joint surfaces of each flange are free of debris. If there is an air leakage, clean the main fuel tank
When the air medium is transported and its dust content exceeds /3, it is recommended to install an air filter (prepared by the user) in front of the air inlet muffler
The muffler should be set On the straight pipe section close to the blower inlet and exhaust port (before the pressure gauge), a safety valve or pressure gauge (prepared by the user) should be installed on the straight pipe section close to the blower inlet and exhaust port. When the fan is overloaded, , the instrument should be able to reflect or send an alarm signal
In order to ensure the safe operation of the blower, the machine is not allowed to carry external loads such as pipes, valves, frames, etc. This kind of load must be supported by an additional bracket, and soft joints must be installed on the intake and exhaust pipes to eliminate the effects of pipe vibration and thermal deformation (prepared by the user)
The installation must be aligned and the blower must be located. The correct position of the motor and the base allows the base and the ground to be adjusted using adjustment pads. The allowable difference is ./mm
It is never allowed to damage the assembly gap of the fan during installation. After installation, the blower rotor should be rotated. Flexible rotation without impact or friction.
