The common fluctuation of outlet pressure of Roots blower can be divided into two situations: one is too high pressure, the other is too low pressure! In both cases, no matter which one occurs, it will cause a certain loss of factory capacity! Therefore, we usually recommend that customers who run Roots fans for a long time adopt a one-for-one approach! In order to start the standby blower in time to solve the temporary production demand after the Roots blower has problems! In particular, customers who have been running Roots blower for more than 5 years should always pay attention to the operation state of Roots blower and carry out regular maintenance of Roots blower! Let's get back to business and discuss the pressure fluctuation at the outlet of Roots blower. First, what if the Roots blower pressure is too high?
Reasons for high outlet pressure of Roots blower:
1.The pressure of a Roots blower depends on the resistance it is subjected to. It will work as long as it is within acceptable pressure range. For example, if you inflate a pool 2 meters deep, the air pressure is 20,000 Pa. In a pond 3 meters deep, it turned into 30,000 Pa. As long as the output power of the motor reaches the load.
2. If the pressure indicated by the pressure gauge is higher than the pressure to be output, it may be caused by pipe blockage, aerator blockage, etc.
The reason for the high motor current is the Roots blower:
1. Compared with the specified pressure, the pressure difference is larger, i.e. the back pressure or inlet pressure is larger and higher.
2. Compared with the flow required by the equipment, the flow of fan is too large and the pressure increases.
3.The inlet filter is blocked and the outlet pipe is blocked.
4.Contact and friction rotating parts (stuck).
Solutions to excessive outlet pressure of Roots blower:
1.Reduce pressure to specified value.
2. Discharge excess gas to the atmosphere or reduce the speed of the blower.
3. Remove barriers.
4.Stop immediately and check the cause.
5.Adjust the oil level to the correct position.
6.Check belt tension and replace with large diameter pulley.
Know how to solve the problem of high outlet pressure of Roots blower, if encounter fluctuation of low outlet pressure of Roots blower, how to solve it?
Generally, the main reasons for the pressure reduction of Roots blower are the increased clearance between impeller and impeller, between impeller and wall plate, and between impeller and housing. Roots blower is a mandatory gas delivery equipment. The pressure of Roots blower is front resistance and is commonly referred to as back pressure. Increased clearance will result in severe gas reflux (increased internal leakage), resulting in lower negative pressure and lower pressure. Other causes of pressure drop: whether a Roots blower or a pipe, if there is a gas leak, it will affect the pressure value of the Roots blower. The leakage is serious and the pressure can not meet the rated standard.
Reduced Roots blower pressure is often caused by other faults. During use, if the pressure drops too much, it should be inspected and repaired in time to ensure the normal operation of Roots blower.
1. Reasons for increased noise.
Roots blower has been in service for ten years, with reduced overall compactness, loosened anchor bolts, brittle muffler and widened gap deviation between components, resulting in increased Roots blower noise.
2.Reduce work stress.
The key reasons for the decrease of working pressure of Roots blower are the enlarged gap, the middle between centrifugal impeller and centrifugal impeller, the middle between centrifugal impeller and plate wall, and the enlarged gap between centrifugal impeller and housing. Roots blower is a forced steam transfer mechanical equipment. Roots blowers display a working pressure of front friction resistance, commonly referred to as steam. The enlargement of the clearance results in a severe return of the vapor body (enlarged internal leakage), resulting in lower air pressure and lower working pressure.
Other causes of reduced working pressure: reduced sealing, regardless of whether the Roots blower is a pipe, if there is a gas leak, the working pressure value of the Roots blower will be impaired and the leak will be more serious. Of course, the working pressure can not meet the rated specifications.
3.Small exhaust volume.
Due to small exhaust volume, large clearance, enlarged clearance, serious internal leakage and reduced exhaust volume of Roots blower. Likewise, leakage of pipes throughout the entire vehicle transportation process can also lead to a reduction in exhaust emissions.
Low exhaust may also be caused by pipe blockage. High pressure and temperature distributed systems are generally used for pipe blockage. To avoid pipe blockage, regular maintenance of the Roots blower is necessary.
