Axual-piston-piston controlled types with adjustable supply and permanent in the direction of the flow of working fluid, designed for the common mash-building use in the hydraulic drives of the corresponding requirements of GOST 17411-91. The pumps are designed to work on mineral oils with a viscosity of 21 to 265 mm2/s (SST) at an oil temperature from +10 to +50 ° C and ambient temperature from 0 to +50 ° C.
Recommended working fluids-Mineral oils of the NPI NP-403 GOST 16728-78, IGP-30, IGP-38 according to TU 38-101413-97.
The nominal subtlety of oil filtration is 40 microns. The class of purity of working fluid 14 according to GOST 17216-71.
Type for adjustable pumps are designed to supply oil under pressure up to 20 MPa in the hydraulic systems of various machines and assemblies.
Depending on the type of supply control, the pumps have the following four performance:
Nar - with a manual supply regulation mechanism and a variable direction of oil flow;
Us - with a monitoring hydraulic mechanism of supply regulation and a variable direction of oil flow;
N4M - with a mechanism of electro -hydraulic supply regulation and a variable direction of oil flow;
Above - with a power regulator with a constant direction of oil flow.
Example of the designation: 1NAS 63/200 UHL4:
1 - auxiliary pump - single -circuit;
On-type of product-axial piston pump;
C - Type of Management - Following Mechanism;
63 - working volume, cm3;
200 - nominal pressure, kg/cm3;
UHL-climatic performance-“moderate-cold climate”;
4 - Placement category
An example of designation when ordering
The pump is an axial piston adjustable with manual supply regulation, fastening on the paws, right rotation, with a working volume of 224 cm3, execution of UHL4.
