LRFM - Ⅱ new hot wind pneumatic isolation series products
Power plant boiler cold wind old structure due to serious leakage and
isolation, and often card for coal pulverizers belt and burned, and mill
bearing such difficult game stopped. In order to solve the above
problem, at the same time, in order to in the boiler operation period
shorter time maintenance stop coal pulverizers (including standby has
completely block, cold and hot air, creating a safe working environment
of urgent requirement.
At the end of 1991, LHPM technology personnel in power planning and
design institute under the support power design institute, northeast and
power, common tieling successfully completed for large and medium-sized
power LRFM type of boiler in the design and manufacture of isolation. In
recent years, LHPM using original advantage, widely absorbs more
technical authority and power system of power plant with each experience
rich scene of technical personnel and the worker concerned according to
the power system, the standard strict test, many improvements in (and)
in practice, thus to improve the following advantages has become LRFM -
Ⅱ cold wind of isolation series products:
1, adopts eccentric clamping and the system of automatic novel
structure, BuKa flexible isolation action.
2, the single cylinder driving sluice gate, to walk more flexible,
accurate, and improve the hoist speed.
3 and seal materials after LHPM special formula, after 10 years of
operation, all the moves in 1,000 times more switches, proved sealing
material in 450 ° c, the situation is not leak wear. The door of action,
not fully sealed condition, the system does not take gas.
4 and the switch and lock door, can automatically through computer
interlocking on remote control, also can be manually near.
5 and LRFM - Ⅱ cold wind type according to the isolation horizontal
installation, perpendicular installation, 45 degrees of inclined
installation, vertical installation.
This series of products has reached the advanced level of the same
products abroad, 94 new product by electric early identification, 95, 99
years of 97, electric power planning by three innings, complete sets of
equipment for 300MW and recommend 200MW thermal power unit and main
auxiliary equipment, and arrangement.
The main advantage
Opening and closing door lock servo driver with servo, two points, and
use the eccentric clamping door, door to door seal packing, around the
block completely.
Servo drive and lock servo, can be in short time (10) to finish within
seconds and closing process, safe operation, convenient. To prevent
leakage of compressed air, gas seal can also be used to make a fan of
cold gas seal.
Operators with pure compressed air cylinder to drive (opens and closes),
can loosen lock on site operation, also can control, with the terminal
signals on feedback switches. Through the door opening and closing of
the cylinder piston driven by gate, gate in the bottom rollers posts to
move freely and in open or closed passage. Every door open or closed
operation of gas consumption as a 0.1 ~ 0.2 cubic meters. Door lock
servo mechanism through the lever to lock in the cylinder piston motion
to prevent heart camshaft partial, and then by the rotation of eccentric
CAM pressure or loosen. The door shut and locked, and by controlling the
loose is automatic control circuit of logic.
This product use point and heat treatment to learn basic principle,
reasonable use of carbon steel, alloy steel, stainless steel, and using
the mixed structure of heat treatment plant, can guarantee the sluice
gate, the overall structure of the door in the environment and within 45
degrees cold and hot huge disparities circumstances not deformation.
