The installation process of Roots blower requires meticulous operation and strict inspection. The following are the detailed steps and precautions for installing Roots blower:
1、 Preparation before installation
1. Equipment inspection: Before installation, the Roots blower and its supporting equipment (such as motor, inlet muffler, outlet muffler, base, elastic joint, pressure gauge, etc.) should be checked for integrity to ensure that the model and specifications of all components meet the design requirements.
2. Preparation tools: Prepare the necessary tools for installation, such as bolts, wrenches, screwdrivers, steel rulers, linear equipment, etc.
2、 Select installation location
1. Position requirement: Select a flat and stable installation position based on the size and weight of the Roots blower to ensure that there is no vibration or displacement during operation.
2. Environmental requirements: Roots blowers should be placed on dry, vibration free ground. The unit can be installed outdoors, but it should be ensured that it is not exposed to sunlight and rain. At the same time, there should be a spacious area of no less than 2 meters around the unit for disassembly, inspection, and maintenance.
3、 Installation base and host
1. Placing the base: Place the base in the pre selected installation position, ensuring that the base is level and stable.
2. Fixed base: Use anchor bolts to fix the base to the ground, ensuring that the base will not move due to the operation of the fan. For large units, it may be necessary to excavate suitable square pits and embed foundation bolts, then connect the fans through bolts and nuts, fill the square pits with cement concrete, and tighten the nuts with force after the concrete is fixed.
3. Place the host: Gently place the Roots blower host on the base, ensuring that the connection holes between the blower and the base are aligned.
4. Tightening bolts: Use matching bolts to securely connect the fan host to the base, ensuring that the tightening torque of the bolts meets the design requirements.
4、 Installation and commissioning of motor
1. Placing the motor: Gently place the motor on the roller connected to the motor on the base, and use the matching bolts for initial connection. At this time, there is no need to tighten it.
2. Adjust the position of the motor: According to the design requirements, adjust the position of the motor to ensure that the motor spindle is parallel to the spindle of the Roots blower.
3. Tighten the motor: Use tools to tighten the connecting bolts between the motor and the roller, as well as between the roller and the base, to ensure the stability of the motor.
4. Install pulleys and belts: Select the fan pulley and motor pulley according to customer parameters, and use a steel ruler or straight-line device to calibrate the two pulleys so that they are on the same plane. Install the matching belt on the fan pulley and motor pulley, adjust the internal and external adjustment bolts of the motor roller to tighten the belt. The state of the belt is that it can be twisted by about 90 degrees when held by hand.
5. Install the wheel guard: Select a suitable tool to install the wheel guard on the fan and tighten the matching bolts.
6. Connect power supply: Invite an electrical engineer to connect the motor power supply and ensure that the cable connection, power supply current, and frequency meet the design requirements.
5、 Install other components and debug
1. Install the pressure gauge: Install the pressure gauge at the outlet of the fan, ensuring that the pressure gauge is installed vertically and the head is facing upwards. Before installation, the rubber cap on the head of the watch should be cut or pierced to balance the air pressure inside and outside the watch case.
2. Install muffler and elastic joint: Install inlet muffler, outlet muffler, and elastic joint at the inlet and outlet of the fan according to design requirements. Pay attention to checking for foreign objects inside the muffler and ensure that the connection is well sealed.
3. Debugging equipment: After connecting the power supply, perform equipment debugging work. This includes checking the tightening of each connection position, whether the pipeline support is tight, and whether the oil level is in the appropriate position. At the same time, turn on the pressure gauge switch to determine if the zero position pressure pointer is accurate.
6、 Trial operation and inspection
1. Trial operation: After the preparation work is ready, conduct a trial operation of the Roots blower. The trial operation is divided into three stages: no-load idle operation, loaded operation, and normal operation.
2. Check vibration: Use a vibration measuring instrument to check whether the vibration of the fan meets the design requirements.
3. Record data: Record the operating data of the fan, such as speed, flow rate, pressure, etc., for future reference.
7、 Precautions
1. When installing the Roots blower, it is necessary to pay attention to sufficient assurance, carefully read the installation instructions, and gradually operate according to the instructions to avoid accidents and equipment failures.
2. Environment: Fans should not be installed in places where people frequently enter and exit to prevent injury. At the same time, fans should not be installed in places that are prone to producing flammable, explosive, and corrosive gases to prevent accidents such as fire and poisoning.
3. Maintenance: After installation, the Roots blower should be regularly maintained and serviced to ensure its long-term stable operation.
From the detailed analysis of the above steps, it can be seen that the installation process of Roots blower requires meticulous operation and strict inspection to ensure the normal operation and long-term effectiveness of the equipment.
