Screw air compressor vibration reasons may be the following:
the deviation of the wheel center is large, which may be caused by the installation error, thermal expansion under the working state, deformation after bearing and uneven settlement of the unit foundation.
The bottom angle bolt is loose, if the bolt is not tight, it will also cause the air compressor to vibrate.
The rotor clearance does not meet the standard, which may be caused by rotor deformation or wear.
Insufficient supply of lubricating oil for the air compressor, or the oil filter has not been replaced for a long time, the poor working environment leads to blockage, and insufficient lubrication causes bearing wear and vibration.
The influence of condensed water, the condensed water with corrosive gas in the air will cause serious corrosion of the rotor, gas seal, diffuser and carbon steel air pipe, etc., resulting in the vibration of the air vortex.
Screw air compressor 2. four impeller welding parts cracking or impeller surface scaling will also lead to vibration. Cracking may be caused by improper welding process or material fatigue; scaling is caused by impurities such as dust or soot in the air entering the compressor and mixing with lubricating oil.
For the above reasons, you can try the following solutions:
find a professional air compressor maintenance engineer to readjust the wheel center to ensure that the deviation of the wheel center is within the allowable range.
Adjust and fasten the anchor bolts to ensure that the bottom angle bolts are fastened reliably.
Check the rotor for deformation or wear and repair or replace if necessary.
Check whether the oil supply regulating valve is fully open and increase the amount of lubricating oil; replace the new oil filter or clean the old oil filter to ensure smooth oil flow.
For the impact of condensed water, air filtration and drying can be strengthened to reduce the entry of corrosive gases and condensed water; at the same time, the rotor, gas seal, diffuser and carbon steel air pipes are regularly inspected and maintained.
For the problem of cracking or scaling of the impeller, it can be repaired by welding or replaced with a new impeller; at the same time, air filtration and fume treatment are strengthened to reduce impurities entering the compressor.
The above information is for reference only, it is recommended to consult professional technical personnel to obtain specific solutions.
The energy consumption of the air compressor is a range of values, which are affected by many factors, including the type of air compressor, specifications, working pressure, flow and operating conditions. In general, the power of small air compressors may be low, usually between a few kilowatts and a dozen kilowatts.
Detecting the oil content of air compressor gas source is a process involving multiple steps and methods. The following are several commonly used methods to detect the oil content of the air source of the air compressor: 1. weight method The weight method is a method of directly measuring the oil content in the exhaust gas. by collecting a certain volume
How to maintain the air compressor: first, regular maintenance and maintenance of the main components: in order to enable the air compressor to operate normally and reliably and ensure the service life of the unit, a detailed maintenance plan must be formulated to carry out fixed-person operation, regular maintenance and regular inspection.
Q: What is the difference between oil-free and oil-free compressors? A: Oil-free air compressor application scenarios In the pharmaceutical, medical, chemical, electronic, environmental protection, semiconductor, textile and other industries with high air quality requirements, oil-free air compressors are required for gas quality.
The water discharged from the air compressor, that is, condensed water, is mainly composed of a mixture of air compressor oil and condensed water, containing harmful substances such as mineral oil lipids, hydrocarbons and synthetic organic matter. If it is discharged directly without treatment, it will cause serious pollution to the environment and ecology. Therefore, must be taken
After a period of time, the after-sales personnel of the screw air compressor will overhaul the air compressor once, replace some filter materials with short time periods of the air compressor once, and overhaul and maintain the air compressor. 1. Clean the valve, clean the valve seat, valve cover carbon deposition, cleaning
Shanghai Granklin Group is a well-known brand in the air compressor industry, with a wide range of products and advanced technology. The group provides a variety of types of air compressors to meet the needs of different customers, including water-lubricated air compressors, oil-free air compressors, frequency conversion air compressors, screw
For the question of whether the 2 cubic compressed air storage tank needs to be reported, the answer depends on the design pressure of the storage tank and other relevant factors. If the design pressure of the gas storage tank is greater than 1kg (or 0.1 MPa), it needs to be reported according to relevant regulations.
The replacement time of the air filter of the air compressor is actually an interesting problem that requires comprehensive consideration of many factors. Generally speaking, a good air compressor air filter can be used for about 1500 to 2000 hours under ideal conditions, and then it needs to be replaced with a new one.
There is a close relationship between workshop gas consumption and gas supply. Simply put, the gas supply should meet the gas demand of the workshop, taking into account efficiency and cost. First of all, the workshop gas consumption refers to the amount of gas actually used by the workshop in the production process. This
