I. Technical performance:
A.Fengyu SF6 Recovery Device can be used to suck, liquefy and store SF6 gas from the insulating equipment. The quality of the retrieved SF6 gas complies with Chinese GB8905-88 standard.
B.To suck air and water from the equipment after maintenance.
C.To store the SF6 gas after it goes through the drying and filtration process.
D.To gasify the liquefied SF6and fill up the insulating equipment again from the store vessel;
E. The drying and filtration device can be activated and reused again.
F. It is equipped with flexible pies and joints for retrieving, storing and refilling processes.
G. General composition
1. Fengyu SF6 Recovery Device is composed of retrieving, filling, filtration, vacuumzing, storing and controlling systems.
2. The device has the merits of good design, rust and shock proof, and reliability.
3. Easy and convenient for maintenance and operation
4. Rotary parts are well protected for safety.
H. Features
1. Vacuumize and check vacuum pressure for retrieving device itself including its storing vessel and pipes;
2. Vacuumize and check vacuum pressure for the insulation equipment
3. Retrieve and store SF6 gas and check the remaining vacuum pressure of the insulation equipment;
4. Get rid of water content and other particulates in the SF6gas with filtration and purification process;
5. Refill up the SF6 gas into the insulating equipment to specified operating pressure.
I. Piping system
Well designed in a vertical or horizontal way, with all connecting joints reliably fastened, well sealed to airtight and dust proof.
J. Store vessel
Designed, manufactured and checked in accordance with Chinese GB150-89 standards for compressed vessels; the vessel is clean inside without remaining particulates, with rust-proof treated inside and well painted outside; it is equipped with pressure gauge, high pressure monitor and relief valve and liquid level monitor;
K. Gas retrieving system
It is composed of air compressor, bumper, separator, filter, heat exchanger, safety valve, one-way valve, gas pressure gauge, vacuum gauge, and freezer;
L. Vacuum system
It is composed of vacuum pump , vacuum gauge(sensitivity≥10Pa )anti-adverse-flow device of vacuum pump oil, and air exhaust pipes;
M. Filter
The filter is designed to efficiently remove water and solid particulates in the oil and prevent them to be carried downstream and also to remove the air originated from the SF6 electric etc. The retrieving system and refilling system have its independent filters.
N. Valve
All valves are well sealed, no leak of air or gas, easy operation and reliability rust proof and long work life;
O. Control panel
Installed with imported pressure gauge(sensitivity ≥ grade 1.5), vacuum gauge, process diagram and operation guide, valve number, and inlet and outlet indicator.
