How to Install A Diesel Generator Set

How to Install A Diesel Generator Set

As a kind of emergency backup power supply machine, the structure of diesel generator set is very complicated. Users should pay attention to some problems in every stage of purchasing diesel generator set to safety acceptance, especially during the installation process. Below is a complete installation instruction of diesel generator set installation provided by Jiangsu Starlight Electricity Equipment Co.,Ltd.

I Preparation work before diesel generator set installation

Generator set Transportation

Users should pay attention to the lifting rope which should be tied to the appropriate position, light lifting light release during transportation. When generator set arrives at the destination, it should be placed in the storage room as far as possible. If there is no storage room need to be in the open storage, the tank pad will be high to prevent Rain Water from encroaching, and the tank should be covered with rain protection tent to prevent the equipment from being damaged by the sun and rain.

Due to the large size and heavy weight of the genset, the handling route should be arranged before installation, and the handling port should be reserved in the machine room. If the doors and windows are not large enough, a larger port can be reserved in the location of the doors and windows. After the units move in, the masonry walls and installation doors and windows will be repaired.

Open the Packing

Dust should be removed before opening the packing to see if there is any damage. Check the packing number and quantity, do not damage the machine when leaving the packing. The open-packing order is to fold the roof first, then remove the side plate. After unpacking, the following shall be done:

①Count all units and accessories according to unit list and packing list;

②Check that the main dimensions of the diesel generator and accessories are in accordance with the drawings

③Check genset and accessories for damage and corrosion;

If the generator set can not be installed in time after inspection, the finished surface of the disassembled machine should be re-coated with anti-rust oil for proper protection. For the transmission and sliding parts of the genst, do not rotate generator set the antirust oil has been cleared. If rust-proof oil has been removed after inspection, reapply it after inspection.

After opening the generator set should pay attention to custody, must be horizontally placed, flange and all kinds of interfaces must be sealed, bandaged, prevent Rain Water and ash sand immersion.

Line location

According to the relationship between the genset and the wall or the center of the column, and the relationship between genset and other genset, the vertical and horizontal baselines of the installation location of the generator are delineated according to the dimensions of the relationship between genset and the wall or the center of the column. The allowable deviation between the center of generator set and the center of the wall or column is 20mm, and the tolerance between the unit and the unit is 10mm.

①Check equipment and ready for installation

②Check the equipment, understand the design contents and construction drawings, prepare materials according to the design drawings, and send the materials to the construction site in sequence according to the construction plan.

③Preparation of lifting equipment and installation tools

II Installation of diesel generator

①Measuring foundation and center line of diesel generator set

②Before the generator set is in place, draw the foundation and the center line of the genset and the position line of shock absorber according to the drawing "release line".

③Hoisting diesel generator set

When hoisting, the steel wire rope of sufficient strength is used in the lifting position of genset, which can not be mounted on the shaft, and it should also prevent from touching the tubing and dial, lift the generator set as required, align it with the foundation centerline and the shock absorber, and level the generator set cushion.

Generator Set Leveling

Adjust the machine to the level with the pad iron. The installation accuracy is 0. 1 mm per meter with vertical and horizontal deviation. There can not have any spacing between the cushion iron and the seat, so that the force is uniform. The exhaust pipe shall be installed with care that the exposed part of the exhaust pipe shall not be in contact with wood or other flammable substances. Pipe extension must allow thermal expansion to occur, pipe can prevent rain, water and so on.

There are two ways to lay the exhaust pipe:

①Horizontal overhead: the advantages are less turning and less resistance; the disadvantage is poor indoor heat dissipation and high room temperature.

②Trench laying: the advantage is good indoor heat dissipation; many shortcomings turn and resistance.

③The temperature of the exhaust pipe of the unit is high, in order to prevent scald operator and reduce the radiation heat to raise the temperature of the machine room, it is appropriate to carry on the heat preservation treatment, the heat insulation material may use the glass wire or the silicate aluminum bandage, may take the heat insulation, reduces the noise function.

III Installation of exhaust system

①The working definition of exhaust system of diesel generator set refers to the exhaust pipe connected to the engine room by the engine exhaust port after the diesel generator set is installed on the basis of the engine room.

②The diesel generator exhaust system includes exhaust pipes connected to the outside of the engine room with a muffler, bellows, flanges, elbows, gaskets, and engine room connections to the engine standard.
