Box diesel generator noise reduction solution storage

The noise intensity and frequency generated by different parts of the unit are different. Therefore, it is very difficult to reduce the noise pollution during operation of the unit, but to meet the requirements of the noise reduction standards of local environmental protection departments and not cause noise to the surrounding environment. Emission of pollution, affecting the normal life of the surrounding residents, and taking measures to reduce the operating noise of diesel generators is also extremely important.

If the necessary measures to reduce noise are not taken, the unit will usually produce 105 to 110dB(A) of noise, and the noise level of the general unit during operation will increase slightly with the increase of the load, and the continuous exposure to more than 85dB ( In the noise level of A), it will cause harm to human hearing.

In most unit installations, noise control becomes very important. There are several methods to choose to control the noise level. Smoke exhaust muffler can properly reduce the noise level of diesel engines. Different levels of mufflers have different noise reduction diesel generator sets. As a result, these mufflers are usually divided into four types: industrial environment, residential environment, high demand, and high demand. HORIS units are equipped with heavy-duty industrial exhaust mufflers at the factory.

In order to achieve the goal of eliminating noise pollution as best as possible, special measures shall be taken and shall be fully considered when the unit is first installed, especially in areas where noise pollution restrictions are strict.

By installing an adequately sized muffler at the air inlet and outlet of the unit, and using a residential type muffling drum with good dust reduction and noise reduction effect, the muffler cotton is stuck on the walls and ceiling of the machine room, and the exhaust gas of the unit is discharged to the highest possible surface. Elimination of nitrogen compounds in exhaust gas by means of chemical reactions, poisonous gases such as sulfides, and filter dust are effective measures to eliminate noise and reduce pollution, and it is recommended that users adopt them.

The following is a brief introduction of one of the most commonly used noise reduction installation examples. It uses a special noise reduction device at the air inlet and outlet of the engine room and a secondary residential type muffler drum in the exhaust system to not only reduce noise. The effect reaches a good level, and the scientific and rational arrangement of the machine room can ensure that it will not increase the exhaust, exhaust back pressure, so that the unit from damage or reduce the unit's power output.

During the design and construction of the unit noise reduction plan, the Changchun generator should fully consider the minimum inlet and outlet air volume standards required for normal operation of the unit and the exhaust back pressure cannot exceed the reference value due to generator elements, otherwise, it will seriously affect the unit. The power output makes the unit body temperature rise higher, so that the unit frequent failure, and even shorten the life of the diesel generator set.

The correct storage and maintenance of the diesel generator sets can greatly extend the service life of the generator sets. Today, we will discuss how to store generator sets in daily life.

In order to facilitate the scientific calculation of the unit warranty period and meet the user's desire to put it into use as soon as possible, and to facilitate the normal heat engine maintenance of the unit, it is recommended that the unit be installed and adjusted immediately after it reaches the use site, and arrange full-time personnel to be responsible for the operation and daily maintenance of the unit. jobs.

If for some special reasons the unit needs to be stored for a period of time, a reasonable and feasible storage plan should be made depending on the length of time required. Long-term storage of the diesel generator set will have a detrimental effect on the diesel engine and the main alternator. Proper storage can minimize adverse effects, so proper storage is essential.

The storage of diesel generator sets shall be carried out in accordance with the steps, including thorough cleaning of the generator set and maintenance of the unit's dry ventilation, replacement of new lubricants of appropriate quality, complete release of the water in the tank and anti-rust treatment of the unit.

The storage place of the unit should be able to ensure that it is not picked up by other items in order to avoid damage. In addition, the user is also advised to build an independent warehouse and to prevent flammable and explosive materials from being placed around the diesel generator set. It is necessary to prepare Some firefighting measures, such as the placement of Class AB foam fire extinguishers, etc.

In order to prevent freezing of the engine and other accessories of the cooling system due to freezing, and to prevent the cooling water from corroding the body for a long time, the unit must be provided with antifreeze when it is used in areas where it is likely to freeze. Refer to the relevant section of this manual for long-term storage. The cooling water in the body and other accessories of the cooling system must be exhausted. Generally, the water tank, body, water pump (if there is a diesel generator port for water discharge), oil cooler (if there is a water outlet), water heater (if any Water outlet). The water in the filter is different for different models.

In order to prevent moisture from entering the main alternator coil and minimize moisture condensation, the insulation performance of the generator is reduced, even affecting the usability of the generator set. Care should be taken to keep the surrounding environment of the generator dry, or to use some Special measures, such as the use of appropriate heating and dehumidifying devices, ensure that the coils always maintain the necessary drying. Refer to the “Alternator Installation and Maintenance Manual” for the procedure.
