  1. 2. Technical data

Pressure oil
mineral oil
Working viscosity range
In order to get the best efficiency and longevity, we recommend choosing the working viscosity (at working temperature) of the oil in the following range:
Vopt = best working viscosity 16...36mm 2/s
Related to tank temperature (open circuit).
Limitation of viscosity range
The limit of viscosity is:
Vmin =10 mm 2/s,
For a short time, under the maximum allowable oil leakage temperature of 90℃
Vmax = 1000 mm 2/s short time, cold start
temperature range(See selection diagram)
t min= -25℃
t max= 90°C

Matters needing attention when choosing working fluid

Matters needing attention when choosing working fluid
In order to select the correct hydraulic oil, it is necessary to know the relationship between the working temperature of the oil in the oil tank (open circuit) and the temperature of the environment.
The hydraulic fluid must be selected to ensure that the working viscosity of the fluid is in the best range (Vopt) within the working temperature range (see the shaded part of the selection diagram). It is recommended to choose the highest possible viscosity grade for each occasion.
Example: At an ambient temperature of X°C, the working fluid temperature is 60°C.
VG46 or VG68 corresponds to the optimum working viscosity range (Vopt; shaded part). Should choose VG68.
Note: The temperature of the leakage oil (case drain oil) is affected by the pressure and speed of the pump and is always higher than the oil temperature. However, the maximum temperature anywhere in the system must not exceed 90°C.
Oil filtration
The finer the oil filter, the better the cleanliness of the working fluid, and the longer the life of the axial piston pump.
In order to ensure the normal function of the axial piston element, the cleanliness of the oil needs to be at least
NAS1638, level 9
18/15 of ISO/DIS 4406
Mechanical displacement limiter
The mechanical displacement limiter only uses the 12/62NOO series plunger pump without shaft, and the maximum displacement can be adjusted arbitrarily from 50%←→100%

Working pressure range-inlet side
Absolute pressure of S port (inlet)
Pabs min 0.08Mpa
Pabs min 3Mpa
Working pressure range-outlet side
Pressure at port B
Rated pressure PN 28Mpa
Peak pressure Pmax 35Mpa
Intermittent work when the load time is 10%, the pressure can reach 31.5Mpa

Table 2.jpg

Case drain pressure
The maximum allowable pressure of leaking oil (L, L1 port): the highest can be higher than the inlet pressure of S port by 0.05Mpa, but not higher than 0.2Mpa absolute pressure.
