CZPT fluid
Ahead of commencing undertaking plHangZhou, make sure you refer to our data sheets RE 95710 (mineral oil), RE 95711 (environmentally satisfactory hydraulic fluids) and RE 95713 (HF hydraulic fluids) for comprehensive information with regards to the decision of hydraulic fluid and software conditions.
The mounted motor AA2FM is unsuitable for operation with HFA. If HFB, HFC and HFD or environmentally appropriate hydraulic fluids are getting employed, the restrictions concerning specialized knowledge and seals pointed out in RE 95711 and RE 95713 have to be noticed.
Particulars concerning the choice of hydraulic fluid
The proper selection of hydraulic fluid demands knowledge of the running temperature in relation to the ambient temperature: in an open circuit the tank temperature. The hydraulic fluid should be picked so that the functioning viscosity in the functioning temperature assortment is inside the the best possible variety (νopt.) – the shaded spot of the selection diagram. We advisable that the larger viscosity course be selected in each scenario. Case in point: At an ambient temperature of X°F (X°C) an operating temperature of 140°F (60°C) is set. In the the best possible functioning viscosity variety (νopt shaded area) this corresponds to the viscosity lessons VG forty six or VG sixty eight to be selected: VG 68.
Remember to be aware: The circumstance drain temperature, which is affected by stress and pace, is usually increased than the tank temperature. At no stage in the system may the temperature be increased than 240°C (115°C) for measurements five to two hundred or 195°F (90°C) for measurements 250 to 1000.
If the above problems can’t be maintained due to excessive functioning parameters, we advise flushing the situation at port U (size 250 to a thousand).
Lengthy-life bearing (measurements 250 to a thousand) 
For lengthy services lifestyle and use with HF hydraulic fluids. Very same external dimensions as motor with CZPT bearing. A prolonged-daily life bearing can be specified. Flushing of bearing and case by means of port U suggested.
Shaft seal ring
The provider daily life of the shaft seal ring is afflicted by the pace of the motor and the scenario drain force. It is advisable that the common, steady case drain pressure at working temperature forty five psi (3 bar) complete not be exceeded (max. permissible case drain stress to 90 psi (six bar) complete at lowered velocity). Brief-term (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.
