Look from left to right, top to bottom.
First open the drawing and look at the annotations in the lower right corner, then read from left to right and top to bottom.
There are two types of wind power generation drawings: installation models and electrical system drawings, and the models can be divided into two types: dual-feed and direct-drive. We take dual-powered motor wind turbines. For example. The whole wind unit can be divided into tower, yaw, nacelle, hub and other parts. Among them, the tower and yaw are relatively simple, focusing on the nacelle and the hub.
How many diesel generators are there in a diesel generator set? What does the legend for a diesel generator look like on a CAD drawing? Is it a legend or a number? Urgent request!
The specific steps are divided into three steps:
(1) MeasureEstablish the vertical and horizontal center lines of the foundation and unit Before installing the generator. The lines must be “drawn” according to the pre-designed drawings, know the longitudinal and transverse center lines of the foundation and the assembly as well as the positioning lines of the shock absorbers. 2) Lifting the unit When lifting, a sufficiently strong steel cable should be used to cover the lifting part of the unit. It should not be placed on the generator shaft or damage the oil pipe and dashboard. Lift the unit according to the unit lifting and installation technical regulations, align the center line of the foundation and the unit shock absorber, hoist the unit to the specified position and level it. (3) Unit Leveling Use pads to level the unit. The method to check if the unit is padded flat is to open the yoke of the wordeur and placing the level on the upper end surface of the cylinder (i.e. the processing reference surface) for inspection. You can also use a level to check the reference plane of the diesel flywheel or the extended end of the crankshaft. Its installation accuracy is that the horizontal longitudinal and transverse deviation does not exceed 0.1 mm per meter. Of course, the higher the precision, the better. There should be no gaps between the skate iron and the bottom of the machine base to ensure uniform stress.
The so-called diesel generator is a diesel generator assembled from a diesel engine and a suitable generator. Therefore, a diesel generator can only have one diesel generator. As for how to mark on the drawing, it depends on the needs. If this is an installation, a legend can be used. If it is an installation design of an eqfactory equipment, a number can be used. However, it is not absolute. because it can be fully explained as needed.
