Screw air compressor abnormal sound solutions mainly include the following:
check and adjust belt tightness:
if the belt is too loose, it may slip. At this time, the adjusting bolt should be turned to adjust the belt to the appropriate tightness, and the deformation should be less than 5mm.
If it still slips after adjusting the tightness, it may be necessary to replace the belt. Pay attention to replacing it all to avoid later damage due to different belt tensions.
Make sure the screw machine is lubricated:
check the oil level of the screw machine, make sure the oil filter is clean, and add oil to the main engine to 3/4 of the rotor.
If the screw machine has not been used for a long time, enough oil should be added to the head before starting up.
Check and replace the faulty component:
if the failure of the intake valve causes air leakage, the faulty valve should be replaced.
For motor bearing failure, judge the problem according to the sound. If the vibration sound of the rolling body is obvious, it may be that the gap is too large, and the rolling body needs to be replaced; the sound is stuffy, it may be that the grease is too dirty, and it needs to be cleaned and replaced with new lubricating oil; if the sound is sharp, it may be lack of oil, and appropriate lubricating oil needs to be added.
Remove foreign material and examine related components:
if there is noise in the cylinder, it may be foreign matter or broken valve plate falling into the cylinder, and the foreign matter or broken valve plate should be removed.
Check the wear of the connecting rod big end bush, small end bushing and piston cross hole, and replace the excessively worn parts.
Check the clearance between the valve plate and the bonnet, adjust the clearance or replace the valve plate if necessary.
Full inspection and fastening:
check the air compressor thoroughly and tighten all possible loose screws and other small objects.
Check whether the fixing bolts of the air compressor are loose and tighten them to relieve the abnormal noise of the air compressor.
Professional maintenance:
if none of the above methods can solve the problem, it may be necessary to ask professionals to overhaul the screw air compressor, especially the overhaul of the host part.
Please note that the above solutions should be carried out under the premise of ensuring safety. If you are not familiar with the maintenance of screw air compressors, it is recommended to seek professional help.
The moisture content of the product after cold dryer treatment is usually between **2%-10%**. The specific water content will vary depending on the material, and the water content of different raw materials will be different. As a low-temperature drying technology equipment, the cold dryer is used in the treatment of food, chemical
Compressed air for medical use shall be treated by multi-stage filtration, drying and sterilization to ensure that the air is free of oil, particulate matter and microorganisms and meets the medical gas standards. The system is usually equipped with redundant design, combined with online monitoring device real-time feedback pressure, dew point and other parameters, to ensure the safety of the medical process.
Q: Why air compressor filter to regularly replace the filter? A: Because the filter continued to be contaminated, will lead to the flow of gas in the system becomes smaller and the pressure drop becomes higher, at the same time, the energy consumption of electricity is also rising. As a result, operations and production and costs are increased.
There is a close correlation between different gas demand and gas supply pipe diameter. In the design and configuration of the gas supply system, we must fully consider the specific needs of gas, in order to select the appropriate gas supply pipe diameter, to ensure the efficient and stable operation of the system. Generally speaking, gas
The air compressor refers to "eight pressures", in the industry usually refers to its working pressure of 8 bar (Bar) or equivalently, 0.8 MPa (MPa). This is a stress level common in industrial and commercial fields and is suitable for a variety of basic applications, including but not
The operating specifications and precautions of the air compressor are the key to ensuring the safe operation of the equipment and extending its service life. The following are the operating specifications and precautions sorted out according to multiple authoritative sources: 1. the operating specifications Check and carefully read the operation of the air compressor before starting up
In the process of electroplating workshop, whether the air compressor needs to run all the time depends on the specific process requirements, equipment configuration and production mode. The following is a detailed analysis from three dimensions: technical principles, actual scenarios, and energy-saving optimization: 1. scenarios that require continuous operation
Screw air compressor is a common type of air compressor. Its performance characteristics and use effects can be summarized from the following aspects: 1. performance characteristics: high efficiency: screw air compressor relies on eccentric operation of the rotor to achieve suction, Compression and exhaust
Oil-injected and oil-free air compressors, both of which can be described as two major "sects" in the field of air compressors, each with its own advantages and unique characteristics. The oil-injected air compressor is like a "master of oil lubrication", which cleverly uses lubricating oil to reduce the pressure during the compression process.
To deal with the problem of water content in the air compressor gas, the following methods can be adopted: 1. installation and regular inspection of the drain valve at the bottom of the cooler drain valve: a drain valve is usually arranged at the bottom of the air compressor cooler. Once you find water inside the air compressor, you should immediately
