Руководство по эксплуатации ФСДВ

Stabilizing filters ФСДВ (hereinafter – stabilizing filters) are intended for final cleaning from mechanical impurities and oil, and also regulation and automatic maintenance of air pressure for feeding pneumatic devices and automation equipment.

 

They are manufactured in two versions: ФСДВ-6 and ФСДВ-10.

 

Type of connection to external pneumatic lines of the air pressure stabilizing filter: 00‑01‑1 (pipe 8х1 mm) or 00‑02‑2 (pipe 6´1 mm) as per GOST 25165-82.

 

Stabilizing filters in corrosion-resistant version “Ор” are intended for operation in an environment containing up to 10 mg/m3 of hydrogen sulfide and (or) sulfur dioxide and, in emergency conditions (for 3–4 h), up to 100 mg/m3 of hydrogen sulfide and (or) sulfur dioxide up to 200 mg/m3.

Design and operation

  1. Pressure stabilizing filters are based on the method of force compensating, at which the moment developed by the setting spring, is balanced by a moment developed by the operating (output) pressure on the membrane.
  2. Operation of pressure stabilizing filter comes to this, that upon variation of operating, or output pressure due to change in input pressure or flowrate of the output air, the force of air acting to the membrane from below varies, and force balance of the stabilizer mobile system is disturbed; consequently, this system is displaced up to obtaining a new balanced position.
  3. In the course of operation, it is necessary to conduct continuous monitoring of the condition of pressure stabilizing filters and the operability of connecting lines.
  4. Filtering element often installed in pressure stabilizing filters, ensures air cleaning with a degree of 99.95%, with proper quality of supply air preparation during at least 3,000 h.

 

General specifications

Input air contamination classes are 3 or 5 as per GOST 17433-80.

Output air contamination classes are 0 or 1 as per GOST 17433-80.

Air purification degree is 99.95% as minimum.

Inlet air pressure:

  • ФСДВ-6 – 0.25 to 0.6 MPa;
  • ФСДВ-10 – 0.6 to 1 MPa.

Setting variation range for the controllable output pressure:

  • ФСДВ-6 – 0.03 to 0.25 MPa;
  • ФСДВ-10 – 0.03 to 0.6 MPa.

Maximal outlet air flowrate is 8 m3/h (ФСДВ-6); 15 m3/h (ФСДВ-10).

Allowable difference between the lower input pressure and the upper output pressure shall be 0.2 MPa as minimum.

Allowable variation in output pressure setting in case of variation of output air flowrate shall not exceed ±0.0135 MPa per each 1 m3/h of flowrate variation.

Allowable variation in output pressure setting shall not exceed ±0.006 MPa in case of variation of inlet pressure within the whole range at temperature of 25°С.
