Regular Maintenance and Check

1. Regular Maintenance

1.1  During the operation, the temperature of casing will increase as the compression ratio increases. If the surface paint scorches, it is abnormal, it means that the friction between the casing and impellers occurs or something is absorbed in, you should stop the blower to make a check.

1.2  The temperature, vibration and sound of the bearings, oil level, oil temperature, inlet pressure, discharge pressure, electric current should be checked regularly.

2. Three-month Check

2.1  Replace the lubricating oil in gearbox.

2.2  Check the V-belt tension.

2.3  Wash the filter bed of inlet silencer.

3. Half-year Check

 Replace the grease in front bearing housing.

4. Yearly Check

4.1  Check the oil seal.

4.2   Check the insides of casing and impellers, adjust clearances.

4.3   Check the bearings and gears.

Operation Precautions

1、The pressure rise can’t exceed the stipulated pressure on the nameplate. Overload will damage the blower and motor, even cause serious problem.

2、During the operation, the temperature rise of bearings can not exceed 75°C, the temperature rise of lubricating oil can not exceed 45°C. In summer, when ambient temperature is high, the SHELL 220# lubricating oil is recommended.

3、The sealing water for wet vacuum pump should be soft water to avoid scaling inside the cylinder.

4、Pay attention to blower operation condition, if abnormal (abnormal sound, vibration, heating), stop the blower to check immediately. And regularly check and record the temperature of bearings and lubricating oil, lubricating oil level and figures on current meter.

5、During operation, if relief valves are opened continuously or frequently, please stop the blower immediately and check to see if the system is overloaded. Try operation after problems have been solved.

6、No attempt should ever be made to control capacity by means of a throttle valve in the intake or discharge piping. Capacity control can be completed by split-flow or changing rotating speed within a permitted range.

7、Please remain the waterway free when you use products with water-cooling construction. If you stop to use them, you should drain off the water at every position and dry them. (To prevent rust and frostbite).

8、When the oil leveler is polluted heavily, please clean or replace it timely so that you can observe oil level easily and make sure the blower lubricated normally.
