Diesel generator set installation specifications
1. Preparations before installing the unit:
1. Transportation of the unit;
Particular attention must be given. during transportation The lifting rope should be tied in a suitable position and lifted gently. Once the unit is transported to its destination, it should be stored in a warehouse as much as possible. If there is no warehouse and it must be stored in the open, the fuel tank must be elevated to prevent it from getting soaked. rain. The tank should be covered with a waterproof tent to prevent it from being exposed to sun and rain.
Due to the large size and heavy weight of the unit, the transportation route should be arranged before installation, and a transportation port should be reserved in the engine room. Once the unit is installed, the walls must be arranged. be repaired and the doors and windowsmust be installed.
2. Unpacking;
Before unpacking, you must first remove the dust and check the box for damage. Check the box number and quantity, and do not damage the device when unpacking. The order of unboxing is to fold the top panel first, then remove the side panels. After unpacking, the following work must be carried out:
①. Check all units and accessories according to the unit list and packing list;
② Check if the main dimensions of the unit; and accessories conform to the drawings. ;
③. Check whether the unit and accessories are damaged or rusty
④ If the unit cannot be installed in time after inspection; Disassembled parts must be surface finished. Reapply rust-inhibiting oil for proper protection. Do not rotate the transmission part and lubricating part of the front unitnt having removed the anti-rust oil. If the anti-rust oil was removed after inspection, it must be reapplied after the inspection.
⑤. The unit after unpacking should be carefully stored and placed horizontally. The flange and the various interfaces must be blocked and bandaged to prevent rain and dust from infiltrating.
3. Line positioning;
Delineate the unit installation based on the relationship dimensions between the unit and the center of the wall or column, and between the unit and the marked unit . on the unit floor plan. The vertical and horizontal reference lines of the location. The allowable gap between the center of the unit and the center of the wall or column is 20mm, and the allowable gap between units is 10mm.
4. Check equipment for installation;
Check equipment, understand design content and construction drawings, prepare materialsx required as per design drawings and deliver materials in sequence. according to construction site People.
If there are no design drawings, you should refer to the instructions and determine the size and location of the civil construction plan according to the purpose and requirements of installation of equipment, taking into account the water source, power supply. conditions of supply, maintenance and use, and establish a plan for the implementation of the units.
5. Prepare lifting equipment and installation tools;
2. Installing the unit:
1. Measure the foundation and the vertical and horizontal center lines of. unity;
Before the unit is in place, the vertical and horizontal center lines of the foundation and the unit as well as the positioning line of the shock absorber must be drawn according to the layout drawing ".
2. Raise the unit;
When lifting, a steel cable of sufficient strength should be used at the lifting position of the unit. It should not be placed on the tree. This should also prevent damage to the oil pipe and dial. Lift the unit, align it with the center line of the foundation and shock absorber, then move the unit. Place the pad flat.
3. Level the machine;
Use the horns to level the machine. Installation accuracy is 0.1 mm per meter in horizontal longitudinal and transverse deviations. There should be no gaps between the iron and the base of the machine to ensure uniform stress.
4. Installation of smoke evacuation pipes;
The exposed parts of the smoke evacuation pipes must not be in contact with wood or other flammable substances. The extension of the flue must allow thermal expansion and the flue must eprevent rainwater from entering.
⑴. Horizontal overhead: The advantages are fewer turns and low resistance; the disadvantages are poor heat dissipation indoors and high temperature in the computer room.
⑵. Installation in trenches: the advantage is good heat dissipation inside; the disadvantages are many turns and high resistance.
5. The unit's exhaust pipe has a high temperature. In order to prevent the operator from being burned and to reduce the increase in engine room temperature caused by radiant heat, it must be insulated. Heat-insulating and heat-resistant material can be wrapped with glass wool or aluminum silicate, can play the role of heat insulation and noise reduction.
3. Exhaust system installation:
1. The working definition of diesel generator set exhaust system signifie that after the installation of the diesel generator set, engine room, the exhaust system is discharged by the engine. The air port is connected to the engine room exhaust duct.
2. The diesel generator set exhaust system includes the standard muffler, bellows, flange, elbow, gasket and engine room connected to the exhaust pipe outside the engine room.
The exhaust system should reduce the number of elbows and shorten the overall length of the exhaust pipe as much as possible, otherwise the exhaust pipe pressure of the unit will increase. This will cause the unit to lose excessive power, affecting its normal operation and shortening its normal lifespan. The exhaust pipe diameter specified in the technical data of the diesel generator set is generally based on a total exhaust pipe length of 6 m and the installation of at least 6 m.read an elbow and a silencer. When the exhaust system exceeds the length and number of elbows specified during actual installation, the diameter of the exhaust pipe should be increased appropriately. The extent of the increase depends on the total length of the exhaust pipe and the number of bends. The first section of piping coming from the unit's compressor exhaust manifold must contain a flexible bellows section. The bellows has been supplied to the customer. The second section of the exhaust pipe must be elastically supported to avoid unreasonable installation of the exhaust pipe or additional lateral stresses and strains caused by relative displacement of the exhaust system due to thermal effects when the unit is in operation. functioning. Compressive stress is added to the unit and all support mechanisms and suspension devices of the exhaust pipe must have a certain degree of elasticity. When there is more than one unit in the engine room, remember that the exhaust system for each unit must be designed and installed independently. It is never allowed to allow different units to share an exhaust pipe to avoid abnormal fluctuations caused by different exhaust pressures of different units when the unit is in operation, increase the exhaust pressure and prevent Smoke and exhaust gases flow back through the shared pipe. affecting the normal power output of the unit may even cause damage to the unit.
4. Installation of electrical systems:
1. Cable Laying Methods
Cable laying methods include direct burial, use of cable trenches and laying along walls. Wait a few moments. .
2. Selecting the cable routing path
Choose the cable routing path WhenWhen choosing the diameter, the following principles should be considered:
⑴ The shortest feed path and the fewest turns
⑵ Make the cable least affected by mechanical, chemical and earth constraints; possible current factors.
⑶. The heat dissipation conditions must be good;
⑸. Avoid planned areas where soil must be excavated.
3. General requirements for cable laying
When laying cables, you must comply with the planning and design requirements of the relevant technical regulations.
⑴ If the installation conditions allow it, a margin of 1.5%~2% can be considered for the length of the cable.
