Installation and Use
1. During installation, the concentricity tolerance of the pump and motor must be less than 0.10 mm (TIR), the maximum allowable angular error must be less than 0.2 degrees, and a flexible coupling must be used; the pump shaft must not bear radial and axial loads; the bracket must be sturdy, rigid, and able to fully absorb vibrations.
2. Secure the pipeline according to the diameter, especially the inlet pipe, and assemble a safety relief valve in the system (inlet flow rate between 0.5 and 1.5 m/s). The set pressure of the safety valve must not exceed the maximum pressure of the pump; the inlet pipe must be strictly sealed and must not leak; the oil tank should be equipped with a diaphragm to separate bubbles and dirt from the oil; the oil return nozzle should be below the liquid level, with a minimum depth of 50 mm, even at low positions, to avoid bubble formation.
3. Set the suction pressure at the pump inlet: +35~ -16.7 KPa for hydraulic oil. +35~ -10.1 KPa for water-ethylene glycol and phosphate ester hydraulic oil.
4. If the pump is installed on the oil tank or above the oil tank cover, the suction inlet height of the pump should be less than 500 mm.
5. The oil should be kept clean, and the pipelines and oil tanks must be thoroughly cleaned; a precision filter should be assembled in the system, with a recommended accuracy of 25 μm, and the oil cleanliness should be within NSA12. A filter with sufficient capacity (rated flow rate should be more than twice the pump flow rate) should be fixed 50 mm above the bottom of the oil tank at the pump inlet, with a recommended accuracy of 100 μm (150 mesh).
6. It is recommended to use anti-wear industrial hydraulic oil or automotive crankcase oil with the letters SC, SD, SE, or SF, with a viscosity grade of 32 to 68 cSt at 40 ℃.
Preferred viscosity at rated speed and pressure:
Minimum 13 cSt Maximum 54 cSt
Minimum 49 ℃ Maximum 65 ℃
7. Check the inlet, outlet, and rotation direction before starting the pump. After fixing the pump, manually rotate the pump shaft smoothly and flexibly. It is best to fill the pump with oil before the first use.
In the initial operation or operation after a long rest, the pump may encounter difficulties in sucking in liquid; in this case, an exhaust valve should be installed on the discharge side in advance, or the air should be discharged by slightly loosening the connection on the discharge side. At startup, operate the pump intermittently without load as much as possible.
8. Do not start the pump when the outlet pressure is lower than the inlet pressure. This will cause operating noise and blade instability.
9. At startup, if the oil viscosity is higher than the suitable viscosity (54 cSt), the pressure should be limited to 50% or less of the respective rated value until the system warms up.
