According to the different fan models, in the ground according to the fan size in the corresponding position to dig out a suitable square pit, and buried in the ground bolts, and then through the bolt, the fan connected to the nut, and finally in the square pit filled with cement concrete, and so on after the concrete is fixed, and then tighten the nut, is the base of the fan and the concrete is firmly connected to together, so that you can reduce the vibration of the displacement of the Roots fan in operation to improve the safety of equipment operation, and because of the reduction of vibration, which also greatly extends the service life of the fan. The operation safety of the equipment, and because of the reduction of vibration, which also greatly extends the service life of the fan.

Other notes.

1. The electrical equipment of the unit should be installed indoors, and the unit can be installed outdoors, but it should be ensured that it is not exposed to sunshine and rain. The inner wall of the room should be designed to avoid reverberation, and the room should be kept dry and well ventilated. Set should be left around not less than 2 meters of generous position, in order to dismantle, overhaul and maintenance. The fan should not be installed in the place where people often go in and out, in order to prevent injuries and burns.

2. The fan should not be installed in a place where flammable, explosive and corrosive gases are easy to produce, in order to prevent fire and poisoning and other accidents.

3. Before installing the Roots blower, you should remove the protection of each part, remove the rust-proof oil of the exposed processing parts, and check the parts for damage and foreign matter inside the machine. It is best to use compressed air to blow the machine clean.

4. When installing the fan, you should check whether the foundation is solid, whether the surface is flat, whether the foundation is higher than the ground.

5. Leveling unit, in the base near the ground bolt below the pad iron, pad iron group should be welded, and then the second grouting, the second grouting is suitable for the use of non-shrinkage cement mortar. First of all, if there is a larger unit, installation leveling, can be considered without padding iron leveling, and then pouring non-shrinkage cement mortar.

6. Before connecting the pipeline to the blower inlet and outlet, the pipeline should be checked whether it is clean and free of foreign matter, and the weight of all pipelines, valves and mufflers should not be added to the blower.

7. According to the environmental conditions, the fan inlet can be selected by the user with its own filter, but should pay attention to the choice of ventilation surface, so as not to increase resistance. In order to reduce the noise, should be equipped with muffler.

8. Roots blower, motor concentricity should be in line with the specifications. With electric oil pump fan, electric oil pump and the main engine should have interlocking start device.

9. The fan can be used for a long time under the ambient temperature of not more than 40℃, and when it exceeds 40℃, it should be installed with exhaust fan and other cooling measures to improve the service life of the fan.

10. When conveying air, methane, natural gas and other media, the dust content should not exceed 100mg/m3.

Installation precautions for Roots blowers are as follows.

1, Roots blower must use flat washers and spring washers to tighten the screws.;

2, it is best to use rubber cushioning rubber to withstand the weight of high-pressure Roots fan, especially high-power Roots blower, essential.;

3, for the Roots blower some of the noise requirements of the occasion, you can add a silencer to reduce the noise, Roots blower silencer installed in the air inlet pipe or the end of the air outlet pipe.;

4, for some of the noise requirements are very high occasions, according to the conditions of the machine itself, plus a layer of silencer sheep, can meet the noise requirements of the scene, specifically consult the manufacturer of the Roots blower or a professional noise control manufacturers.;

5, Roots blower in the use of silencer sheep silencer, pay attention to the distance between the Roots blower and the box, pay attention to the Roots blower ventilation and heat dissipation, pay attention to the use of rubber cushioning rubber to withstand the weight of the pressurized blower, the specific need to consult the manufacturer of the Roots blower.;

6, Roots blower inlet and outlet pipe connection, should use hose connection, in order to isolate the vibration.

7, the foundation should be enough weight (not less than three times the weight of the equipment, except for special vibration-damping frame), area and capacity, the foundation should be firm, the surface should be flat, and should be higher than the ground 10-25cm

8, the installation to ensure that the unit level, the number of pad iron, location distribution in line with the requirements of the pad iron and the foundation contact area of not less than 40%.;

9, the motor to avoid direct start;

10. No debris in the body and piping.;

11, to confirm the import and export direction is correct, not installed in reverse; import and export pipe has a soft connection, to prevent external load transfer to the fan.

12. The sealing parts shall not leak.;

13, the belt disk wheel parallel, tension moderate.

14, refueling, inspection, disk, test drive.
