3.2 Function 3.2.1 Lubrication unit A chain lubrication system comprises the different pneumatic, hy- draulic, mechanical and electronic components necessary to an opti- mal lubrication. The figure beneath shows an example of a lubrica- tion installation. It comprises the following main elements: •... - Page 12 3.2.2 GVP system The function principle of the grease injection system for the lubrica- tion of conveyor chains is more or less the same for all systems. However some models differ from others by the type of lubrication points, the number of injection heads, etc. In the following description of the GVP system function the chain runs upwards.

It might be necessary to adjust the position of the proximity switch according to the chain speed and the system response time. This manual adjustment is done empirically. Therefore SKF recommends to use a switch support with an ob- long hole parallel to the chain to make the adjustment easier. - Page 19 Fig. 12 It is important to correctly position the proximity switches in relation with the lubrication point to guarantee an optimal function. The proximity switches must be perfectly positioned in the axis of the point to be detected († fig. 12). Sa : 0 <...
