Regulators differential pressure type RPD-3/120-1 are designed to maintain a given drop (differential pressure) of the oil over gas.
Climatic conditions:
Temperature from +1 to +60°C, relative humidity 98% at 35°C.
Specifications:
The working environment for the modification RPD-3/120-1:
- oil turbine brand AP-22s THAT 38.101821-83 with a purity of not
below 10th grade purity liquid according to GOST 17216-71 temperatures from +30 to +60°C;
- natural gas or compressed air temperature from +5 to +60°C.
The pressure of air or gas: 12 MPa (120 kgf/cm2).
Conditional throughput (flow rate) when the oil pressure not more than 0.5 MPa (5,0 kgf/cm2): (250±10) l/min
Static irregularity (proportional band) is not more:
- 0,035 MPa (0,350 kg/cm2) at a flow rate of oil from 10 to 140
l/min;
- 0.06 MPa (0,60 kg/cm2) at a flow rate of oil from 140 to 250 l/min
Adjustment range oil pressure when the flow rate (250±10) l/min: 0.5 to 1.5 MPa (from 5.0 to 15,0 kgf/cm2).
View adjustment range oil pressure: manual.
Limits settings (setting) differential pressure oil and gas:
- top - 0, 3 MPa (3.0 kgf/cm2);
- bottom - 0,04 MPa (0,40 kg/cm2) at a flow rate of the oil to 140 l/min;
- 0.07 MPa (0,70 kg/cm2) at a flow rate of oil from 140 to 250 l/min
Response time: not more than 0.5 C.
Weight, not more than: RPD-3/120-1 - 20 kg;
RPD-3/120-1 EO - 27.5 kg without oil and 28.0 kg of oil.
