There may be many reasons for the large vibration of screw compressors, including the following common situations:
the anchor bolts of the unit are loose or the rigidity of the frame is poor.
Poor alignment between compressor and prime mover.
Unbalanced compressor rotor or worn bearing.
There is friction inside the compressor or the gap between the rotors does not meet industry standards.
The unit pipeline produces resonance.
Excessive liquid or lubricating oil is sucked into the cylinder, which may be caused by insufficient oil supply or clogging of the oil filter.
The gap between the male and female rotors does not meet the requirements, or the rotor is deformed.
The clogging of the precision filter affects the normal passage of compressed air.
Intake valve not fully closed, check valve vibration, loose gear bolts or belt drive compressor belt slip, etc. may also cause vibration.
In order to solve the problem of large vibration of screw compressors, the above reasons can be investigated one by one, and corresponding solutions can be taken, such as tightening loose bolts, replacing worn bearings, adjusting rotor clearance, cleaning or replacing filters, adjusting intake valves, etc. In the maintenance process, it is recommended to consult a professional technician or contact the mechanic for adjustment and repair.
Please note that the above information is for reference only, and the specific reasons and solutions may vary depending on the equipment model and usage environment. If you cannot solve the problem by yourself, it is recommended to contact a professional maintenance team for inspection and repair.
Oil-free air compressor does not need to add oil at all in the compression chamber of the main engine, but some mechanical transmission parts (such as motor bearings, gearbox, etc.) still need regular lubrication and maintenance. The following is a specific analysis: 1. host compression cavity: the core design technology principle without refueling: Oil-free air compressor
The maintenance cycle of the new air compressor can be determined according to different situations. The following are some general guidelines: First maintenance: It is usually recommended that the new air compressor be maintained for the first time after 500 hours of operation. This maintenance is relatively simple, mainly to change the oil,
The provisions on the design service life of pressure vessels mainly come from national standards, industry norms and the agreement between the design client and the design unit. Specifically, it can be summarized into the following aspects: 1. national standards and industry norms "fixed
The coalbed methane compressor is a key equipment specially used in the process of coalbed methane mining and transportation. The following is a detailed explanation of coalbed methane compressor: 1. definition and use Coalbed methane compressor, as the name implies, is used to compress coalbed methane (also known as coal mine gas or coal seam A
In view of the fact that the air consumption of a certain equipment is 108 cubic meters per minute, the following factors need to be considered in the selection of air compressor: the air consumption of the equipment is the key parameter for selection. In this case, the air consumption is 108 cubic meters per minute, so the selected air compressor
The size of the air compressor used in the factory depends on many factors, such as the size of the factory, the number of production lines, and the demand for equipment. Generally speaking, small and medium-sized factories may only need smaller air compressors, while large factories may need several large air compressors to meet production.
The core difference between fixed-frequency screw machine and variable-frequency screw machine is reflected in four aspects: operation mode, energy efficiency performance, stability and applicable scenarios. The specific analysis is as follows: 1. operation mode: fixed speed vs dynamic adjustment fixed-frequency screw machine: motor speed is constant, through adjustment
Oil-free water lubrication screw air compressor is now the air compressor industry leader, its working principle is better than the twin screw air compressor, has six characteristics as follows: 1. Good structure: single screw air compressor two star wheel in the symmetrical position on both sides of the screw, so that single screw air pressure
Air compressor (air compressor) as a general machinery, in various fields of the national economy has a wide range of applications. Its core function is to convert mechanical energy into gas pressure energy to provide power source or control medium for equipment. The following are the main application areas and industry distribution: 1. core applications
In fact, we should pay attention to some principles when choosing an air compressor, so that we can compare and choose what is more suitable for us and pay attention to when choosing an air compressor. 1, to consider the safety of compressor operation. Air compressor is a
