How to control the noise of natural gas compressor in gas station

The specific treatment methods are:

1. If the noise disturbs the people, you can complain to the environmental protection department, and the environmental protection department shall rectify it within a time limit if it is determined that it exceeds the emission standards stipulated by the state, and if it still fails to meet the standards after the expiration of the period, it can be fined and ordered to stop production and business.

2. Generally, a sound insulation cover can be made to isolate noise. According to actual needs, it is divided into detachable sound insulation cover and non-detachable sound insulation cover; The characteristics of the non-detachable structure are: a large cover of cement structure, bulky, good sound insulation effect, non-detachable; The detachable structure is characterized by:

A folding steel plate clamp sponge structure, convenient, detachable, compared with the non-detachable type, the sound insulation effect is not very good.

Generally, a sound enclosure can be made to isolate the noise.

1. The engine has abnormal noise.

Symptom description: There is a lot of abnormal noise in the engine compartment, and most people also judge it to be the abnormal noise of the engine compartment by the sound**, which is usually a metal screeching sound or a howling sound.

Solution: The abnormal engine noise indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment.

Some abnormal noises can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding.

It should be reminded that if it is an abnormal noise in the engine, most of the owners will not be able to solve it by themselves, and it is best to send it to the factory for maintenance.

2. There is abnormal noise in the gearbox.

Symptom description: If there is a "rustle" sound inside the gearbox while the car is driving, and there is no more after pressing the clutch or accelerator, there will be a whistle-like sound when changing gears.

Solution: There are many transmission parts, and the reasons for the sound are more complex, so we should pay attention to whether it is related to a specific speed, such as some planetary teeth that sound at about 50km h.

Whether it is related to certain gears, which is very important for judging the failure of the transmission, if a certain gear sounds, it must be related to the components that affect the transmission of the gear; If all gears sound, it is often a common meshing shaft failure or a lack of oil in the transmission. Whether it is related to specific actions, such as increasing and decreasing gears, starting, rapid acceleration, sharp deceleration, turning, etc., are effective means to judge abnormal noise, among them, changing speed and direction are particularly important for judging the rear axle fault.

If the abnormal noise of the transmission is obvious, it is recommended to send it to a professional repair shop to check the faulty parts, and then replace them.

3. There is abnormal sound of wear.

Symptom description: When driving on the accelerator or brake, there is always some abnormal noise in a certain part of the body, the sound is not loud, and it does not affect normal driving, but it always makes people worry a little about the failure of the body.

Solution: The abnormal noise of the door is mainly caused by the lack of lubrication, but it is necessary to judge whether it is the position of the door hinge or the glass regulator, door lock mechanism, handle mechanism, etc. inside the door. In the case of door hinges or limiters, special door hinges and slide grease can be used, while special door attachment grease is used for lubrication of glass regulators, door locking mechanisms, handle mechanisms, etc. inside the door. In terms of brand selection, try to choose the commonly used brands in 4S stores, such as German Marty, Kluber, Tiger Head Hotolube, Fox, etc.
