Screw compressor at the start of the loud noise may be caused by a variety of reasons, the following are some possible reasons and solutions:
motor or transmission system failure: Motor or transmission system failure, such as bearing damage, gear wear or shaft shaking, may cause abnormal vibration or noise of the screw compressor. Damaged parts such as bearings or gears should be inspected and replaced.
Damage to the internal parts of the screw machine: If the screw, bearing and other internal parts are damaged, the screw machine will run unstable, resulting in abnormal vibration or noise. Damaged parts should be inspected regularly and replaced.
Improper installation of the screw machine: installation problems such as weak foundation and low levelness may also cause unstable operation of the screw compressor and abnormal vibration or noise. It should be ensured that the screw compressor is installed on a firm and horizontal foundation.
Poor use environment of the screw machine: environmental factors such as too high temperature, too low or too high humidity may also affect the normal operation of the screw compressor, resulting in abnormal vibration or noise. The use environment should be improved to ensure that it operates under suitable temperature and humidity conditions.
Lubrication problems: When the screw compressor is running, if the lubricating oil is insufficient or excessive, it may cause abnormal noise. It should be ensured that the amount of lubricating oil is moderate and regularly checked and replaced.
Seal failure: If the seal in the screw compressor fails, it may cause the internal pressure of the compressor to drop, causing vibration and noise. Failure seals should be checked and replaced periodically.
In order to reduce the noise when the screw compressor starts, the following measures can be taken:
regularly maintain and inspect the screw compressor to ensure that it is in good working condition.
Pay attention to the installation and use environment of the screw compressor to ensure its stability, level and appropriate temperature and humidity.
Add lubricating oil in strict accordance with the prescribed standards to avoid too much or too little.
If the screw compressor is found to have abnormal noise, it should be stopped in time to check and take corresponding measures.
In the world of semiconductor manufacturing, there is a very strict set of standards for the gases used, just like the selection of ingredients and spices in a high-end food production process. So, what are these "picky" standards?
Today, with the highly developed automation of food enterprises, compressed air has been widely used. For some special processes in the food industry, compressed air may also come into direct contact with the product. Like some special chemical areas, the air may have been polluted, such
In the medical field, air compressor units play a vital role, especially in the supply and treatment of medical gases. The water-lubricated screw air compressor produced by Shanghai Granklin Group, with its excellent performance and environmental protection characteristics, has become a medical gas system.
The frequency conversion and power frequency of the screw air compressor have their own advantages and applicable scenarios, and it is impossible to simply say which is better. Below I will compare them in detail to help you make a more informed choice. Energy saving effect: variable frequency air compressor can be based on the actual
Answer: Hospital oxygen supply, medical oxygen compressor can provide high-quality oxygen for the hospital. Mainly to provide sufficient, clean oil-free air source for medical and health care equipment requiring air source, suitable for dental equipment.
Presumably everyone knows that oil-free air compressors are now used in many industries, but presumably you don't know what kind of role oil-free air compressors play in all walks of life. Today we will enter all walks of life and have in-depth application of oil-free air compressors.
Medical gas plays the core role of "life support system" in medical treatment, and its importance is reflected in many dimensions, such as directly participating in patient treatment, ensuring the operation of medical equipment, maintaining surgical safety and infection control. The following is a systematic analysis: I
The automatic drainage of air compressor tank is mainly realized by automatic drainage valve. The following is a detailed introduction to the automatic drainage of the air compressor gas tank: The working principle of the automatic drain valve: There is usually an air bottle or buoy in the automatic drain valve. When the storage
answer: screw air compressor has many advantages, such as high stability, high efficiency, small vibration, low noise. The male and female rotors of the screw compressor and the cooperation between the rotor and the casing are set, so that the backflow of gas
In the process of chemical synthesis, process compressed air plays a vital role, and its application runs through many key links. The specific functions are as follows: Provide oxidants 1. chemical reactions and synthesis: Oxygen in compressed air is an important oxidant for many chemical reactions. Example
