Centrifugal pumps of sectional types of central nervous system 60

Centrifugal pumps of sectional types of central nervous system 60

Sectional centrifugal pumps (hereinafter referred to as the pump) type 60 are designed for pumping water up to 45 ° C, central nervous system (d) 60 are designed for pumping water with a temperature of up to 105 ° C, with the content of solid mechanical impurities of not more than 0.1 % in weight, at The size of solid particles is not more than 0.1 mm, microcharged not more than 1.47 GPa. The maximum permissible pressure at the entrance to the pump is not more than 0.25 MPa (2.5 kgf/cm2).
The pump should be made in the climatic design of the UHL, the placement category 4 GOST 15150-69.

The pump centers 60-66 has a designation:
Central nervous system - centrifugal section of sectional;
60 - nominal feed in m3/h;
66 - pressure in m.

Pump description

The working part of the characteristics at a rotation frequency of 2950 rpm is located in the supply range of 47 ... 75 m3/h.
The main parameters of the pump corresponding to the nominal mode of operation on water with a temperature of 20 ° C and a density of 998.2 kgf/m3

Permissible ultimate pressure deviations from +5 % to minus 3 %;
The permissible pressure reduction during operation by 20 % of the value indicated in the table;
The power is indicated in the nominal mode, excluding the admission to the pressure.

The maximum permissible pressure at the entrance to the central nervous system is not more than 0.3 MPa (3 kg/cm 2 < Span Style = "Color: Rgb (51, 51, 51);">).

The minimum acceptable pressure at the entrance to the Central Military Council pump is at least 0.1 MPa (1 kg/cm 2 < Span Style = "Color: RGB (51, 51, 51);">), the maximum allowable not more than 0.3 MPa (3 kg/cm 2 ).
The pressure at the entrance to the Central Military Service pump, depending on the oil temperature, should be in the range from 0.015 to 0.06 MPa (0.15-0.6 kg/ cm 2 ) O. -serif; Font-Size: 16px; Background-Color: RGB (239, 239, 239); " /> The pressure at the entrance to the Central Military District pump should be in the range from 0.05 to 0.3 MPa (0.5-3 kg/cm 2 ).
