CZPT fluid
Just before starting undertaking plHangZhou, make sure you refer to our information sheets RE 95710 (mineral oil), RE 95711 (environmentally suitable hydraulic fluids) and RE 95713 (HF hydraulic fluids) for comprehensive information concerning the choice of hydraulic fluid and application conditions.
The mounted motor AA2FM is unsuitable for operation with HFA. If HFB, HFC and HFD or environmentally satisfactory hydraulic fluids are being used, the limits regarding complex information and seals mentioned in RE 95711 and RE 95713 need to be noticed.
Specifics with regards to the option of hydraulic fluid
The correct decision of hydraulic fluid requires expertise of the functioning temperature in relation to the ambient temperature: in an open circuit the tank temperature. The hydraulic fluid ought to be chosen so that the running viscosity in the functioning temperature range is inside the ideal assortment (νopt.) – the shaded location of the selection diagram. We suggested that the increased viscosity class be selected in every circumstance. Example: At an ambient temperature of X°F (X°C) an running temperature of 140°F (60°C) is set. In the the best possible functioning viscosity variety (νopt shaded location) this corresponds to the viscosity courses VG 46 or VG sixty eight to be chosen: VG 68.
You should observe: The circumstance drain temperature, which is influenced by stress and speed, is usually increased than the tank temperature. At no position in the technique may the temperature be larger than 240°C (115°C) for dimensions five to two hundred or 195°F (90°C) for dimensions 250 to one thousand.
If the above circumstances cannot be taken care of due to excessive working parameters, we advocate flushing the circumstance at port U (dimension 250 to a thousand).
Long-life bearing (sizes 250 to one thousand)
For lengthy provider daily life and use with HF hydraulic fluids. Identical external proportions as motor with CZPT bearing. A extended-daily life bearing can be specified. Flushing of bearing and scenario by means of port U recommended.
Shaft seal ring
The provider lifestyle of the shaft seal ring is afflicted by the speed of the motor and the situation drain pressure. It is advisable that the average, ongoing scenario drain strain at working temperature 45 psi (3 bar) complete not be exceeded (max. permissible case drain pressure to ninety psi (six bar) absolute at reduced speed). Quick-expression (t < 0.1 s) pressure spikes of up to 145 psi (10 bar) absolute are permitted. The service life of the shaft seal ring decreases with an increase in the frequency of pressure spikes. The case pressure must be equal to or greater than the external pressure on the shaft seal ring.
