Pneumohydraulic controller HP 036./HP 037.
The fluid intake filter is located on the gear pump. Once the nut has
been removed (see fig. on right), the filter insert can be taken out. If
heavily soiled, the filters should be replaced. Depending on the de
-
gree of soiling, the fluid tank should be clean ed. Prior to reassembly,
the old silicon seal must be removed from the fluid tank and the valve
assembly and replaced by a new brush-on silicon sealant.
The air jets must be checked regularly for soiling and cleaned as
required.
The hose lines on the pneumatic sensor must be remo
ved for cleaning purposes as otherwise the compres sed air
would destroy the diaphragm in the servovalve.
The air jets in
the pneumatic sensor should be flushed out with compressed air. In
the case of extreme soiling, the sensor should first be cleaned with
petroleum ether or paraffin. The hose lines may also have to be clea
-
ned.
Do not clean the pneumohydraulic controller with com
pressed air. Compressed air will destroy the controller.
