Introduction to common faults of Roots blower aerator valve

To extend the service life of Roots aerator:

1. Check the oil level of Roots aerator. Too much or too little lubricating oil will damage the bearing.

2. Check the temperature of main and auxiliary oil and bearing parts.

3. Check the suction and discharge pressure to confirm whether the fan operates normally.

4. Check the motor load of Roots aerator. If the motor load increases, it indicates that there is some abnormal condition. Find out the reason.

5. Check the packing sealing effect of Roots aerator. Aquatic oxygenator is very helpful in the aquatic industry. It can solve the problem of hypoxia in aquatic products.

Role of adding lubricating oil to Roots aerator:

In winter and summer, Roots aerator uses different lubricants. The key is the type of lubricating oil. Under normal circumstances, 68 # engine oil is used in summer and 46 # engine oil is used in winter. The engine oil should be replaced every three months.

Its function is to reduce friction. The presence of a lubricating film prevents direct contact with metal surfaces and significantly reduces friction and wear. Good heat dissipation effect. Due to friction, a lot of heat will be generated at high speed. If the heat is not dissipated in time, the temperature will rise and the parts will burn. Protection. The metal sheet was rusted, and a layer of grease was coated on the surface to prevent rust. Good sealing effect. Applying lubricating oil on the seal packing and shaft seal can effectively play a sealing role, prevent liquid leakage and prevent dust from entering. Good washing effect. Especially in the circulating thin oil lubrication system, the friction surface should be washed frequently to remove dust to avoid scratching the friction surface.

Common faults and solutions of Roots aerator valve:

1. The valve body is damaged and cracked;

The corrosion resistance of valve material decreases. Settlement of pipeline foundation. The pipe network pressure or temperature difference changes greatly. Water hammer; Improper operation of closing valve, etc. The external causes shall be eliminated in time and the valves or valves of the same model shall be replaced.

2. Transmission device failure, which is often manifested as valve stem jamming, inflexible operation or valve inoperability.

The valve will rust after being closed for a long time. Improper installation will damage the valve rod thread or valve rod nut. The valve is stuck in the valve body by foreign matters. The ram is usually half open and half open, and the valve stem screw and valve stem nut are misaligned, loose or engaged due to water or other impact forces. The valve stem is locked because the packing is forced past. The valve stem has been drained or blocked by the discharge parts. Lubricate drive components during maintenance. Tap gently with a wrench to avoid blockage and drainage. Stop water supply or replace the valve for maintenance.
