The main functions are the same. They might be also some slight dimension differences. For further information, please refer to the technical documentation delivered with the GVP system or contact the SKF Service Center. Legend fig. 1 1 Injector cylinder 2 Injector carriage...
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: •...

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.

Moving direction You have to take in account the moving direction of the chain when installing the lubrication system.
4.2 Mechanical adjustments D A N G E R ! Adjustments to the pick-up system must only be made when the pneumatic feed is shut off and the chain stopped. The position of the lubrication system must be mechanically adjust to optimize the lubrication process.

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.

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 <...
5 Transport, delivery and storage 5.1 Transport SKF products are packaged in accordance with the regulations of the recipient country and in accordance with DIN ISO 9001. Our prod- ucts must be transported with care. Products must be protected against mechanical influences such as impacts. Transport packaging must be labeled with the information 'Do not drop!'.

Fig. 18 The lubrication system GVP must be disconnected from the power supply and not under pressure when modifying the metered volume. Therefore turn off the power supply and depressurize the system. • Check the GVP unit is off and the air supply closed. •...
6.4.2 Lubrication system bleeding Fig. 22 The supply system shown here to describe how to bleed the lubrication system is given as example. This is a pneu- matic drum pump controlled by an pneumatic control unit. Ac- cording to the application, the supply system may be different. For further information, please refer to the technical documenta- tion delivered with the lubricant supply system.
Lubricants can contaminate the ground and watercourses. Lubricants must be used and disposed of in compliance with the rules. Instructions and local regulations must be observed when handling lubricants. The system can also be taken back by SKF for disposal if the costs are covered.
SKF products are low-maintenance. However, to ensure that they function properly and to avoid risks right from the startup, all joints and connections should be checked to make sure that they are prop- erly fitted.
Doing so invalidates all Table 2 gives an overview of possible malfunctions and their causes. warranty claims. If you are unable to rectify the malfunction, please contact SKF Ser- All other work relating to installation, maintenance, and repair vice Center.
