Installation and fixing:

1. installation factors

The factors that need to be considered in installing a generator are:

A. floor loading

B. channel and maintenance position

C. vibration, ventilation, smoke pipe connection and heat insulation

D. room noise reduction

E. fuel tank size and location

F. local or national environmental regulations

2. location of generator set

A. the installation of a generator usually consists of the basement, the ground, or the roof.

B. usually the generator room should have enough room for air circulation

Adequate work should also be left in the vicinity of the C. engine and alternator.

3. generator set fixed

Generator a correct at the time of shipment has been made by the machine mounted on a rigid base, has accurately adjusted the alternator and engine, which only needs to be installed at a predetermined position (larger units need to install the shock pad, and the level of place).

4. earthquake resistant device

The Cummins Cummins generator unit is attached to the shock pad to prevent the machine from receiving or transmitting harmful or unsuitable vibrations. Rubber shock absorption pads are available when a small amount of vibration is transmitted.

5. floor loading

The weight of the floor depends on the weight of the entire generator (including fuel and water), the size of the volume and the number of cushion pads. If the base is directly fixed to the floor, the floor is loaded:

Weight of the entire generator set

The floor area of the slide bearing = conducting

If a cushion is provided and the weight of the generator is equally distributed on each of the pads, the floor is loaded:

Weight of the entire generator set

Floor load = cushion cushion area ------------------------ * number

Therefore, the weight of the floor can be reduced by increasing the number of cushion pads.

If the weight is not evenly distributed, the maximum floor pressure will be generated on the cushion that supports the largest weight (assuming all the pads are the same size).

The weight of the largest shock absorption pad

The maximum pressure = ---------------------------- floor cushion area

Ventilation and cooling:

The operation of the engine and the operation of the alternator heat the engine out of the engine room and improves the temperature of the room. Therefore, the ventilation of the generator room is required. It effectively controls the temperature of the engine room and provides the generator with cool and fresh air.

1. cycle

Good ventilation requires adequate air to flow in and out, and circulate freely in the room. Therefore, the engine room must be large enough to allow the air to circulate freely so that the air temperature in the engine room can be balanced and free of trapped air.

2. vents

To allow fresh air to enter the engine room, there should be an open air inlet or vent to the other part of the building to allow adequate air to enter. In smaller rooms, air pipes can be used to pump air into the room or directly to the air intake of the engine. In addition, there should be a row of air vents open outside the wall so that hot air is expelled from the mouth.

The shutter shall be protected against wind and exhaust. These windows can be fixed, but they are best adjusted when the temperature is low. For automatic starting generators, the shutters are best operated automatically so that they are opened immediately when the engine is started.

3. inlet size

Before calculating the size of intake air vents, the cooling air flow at the radiator and the static pressure generated by the fan at the rated load must be taken into account. Installed in the standard room, the heat emitted has been calculated in the radiator air flow. For those machines in which the radiator is installed in the distance, the cooling air flow is calculated by the total heat delivered by the engine, alternator and exhaust system to the surrounding space.

When the generator operates at rated power, the amount of cooling air required by the engine and alternator is specified in the specification document. The heat insulation material on the exhaust system in the use of smoke in the room and the length of the tube, so the air flow calculation of the room, the heat from the heat can not ignore.

After determining the air flow into the room, it is possible to calculate how large the ventilation inlet should be on the exterior wall. The ventilation inlet must be large enough so that the airflow resistance will not exceed 0.4inH2O. The resistance values of air filters, window curtains and blinds can be obtained from manufacturers of these accessories.

4. dimensions of air vent

And when the engine room is composed of a fixed on the generator cooling radiator, air vents must be large enough to allow all circulation in the room air, not including the relatively small amount of air entering the engine entrance.
