10） The technical specification of guide barrel of strobe storage room
The guide barrel of storage room is used to store the strobe vertically. The guiding device includes splice plate and angle steel part which are fixed to the wall of storage room. The guiding device is installed below an operation platform, keeping in a vertical position. The supporting block of guiding device upholds the strobe above the pit base, avoiding the seal from contacting the concrete structure. The plastic surface of supporting block is used for preventing damage to paint of strobe during contact. 2 HPX pump rooms have set 8 storage rooms to store 16 strobes, which are 5.5m wide.
d） Drum-shaped filter screen
Drum-shaped filter screen shall comply with RCC-M Grade 3.
1）General
The drum-shaped filter screen is a rotating cylinder whose circle is installed with net slices. Water flows into the drum-shaped filter screen from ends on both sides and discharges outside along the circle after being filtered by the filter screen. When the drum-shaped filter screen rotates, the dirt interrupted by filter screen is brought onto the operation platform, washing it to a dump tank and draining it through drain. The rotating structure is composed of a drum-shaped filter screen frame, which is an outward-emitting spoke support through the hub installed on the main shaft. Both ends of main shaft are supported by an automatic center adjusting double-row sphere roller with spherical surface in bearing seat. In the bearing seat on one end of the main shaft, a brush-type feed mechanism of extra current cathode protection system is installed. Both sides of drum-shaped filter screen are set with a grease-box with alarming switch for low oil level. The exterior surface of filter screen is composed of separate and replaceable net slices which are fixed to the circle of drum-shaped filter screen framework by bolts and nuts.
During rotation, the drum-shaped filter screen is sealed by contact of flexible molding rubber seal plate with pressure plate and fastener installed on exterior of framework structure and low-friction seal plate installed on the fixed sealed angle steel on the wall of water chamber.
Dirt picking bucket is fastened onto the horizontal beam in drum-shaped filter screen for lifting large blocks of dirt. The railing is set on the passage to operation platform of backwashing device with a drum-shaped filter screen, and a stairway is built from passage of operation platform, anti splash housing, clearing dirty device to the working platform. The backwashing pipes installed in the anti splash housing are two pipelines of 100％ capacity, and it is possible to check and repair the nozzle when raising the cover of anti splash housing.
When the drum-shaped filter screen rotates, the net slices rotate across the dirt discharging bucket which is washed by the nozzle installed on fully wide net slices of drum-shaped filter screen. The nozzle is connected to the backwashing pipe by swift-changed joint, which is easy to clean and replace. The backwashing pipe is installed with a pressure measuring meter. The dirt accumulated in dirt discharging bucket and flushing water are discharged through concrete drainage. The rotation of drum-shaped filter screen is driven by pinions on transmission shaft of driving device and big gear ring in the central loop of drum-shaped filter screen framework. The transmission shaft is supported by a pair of separate roller bearings which are connected to the combined reducer, and the reducer is driven by an independent low-rate and a double-rate motor (middle/high rate). Additionally, there is a standby low-rate motor which is installed in reducer for emergency. Over loading protection of torque for driving device is realized by skip of electronic power monitor on a main panel installed at other where. The motor is equipped with moisture-proof heater in order to avoid the generation of negative potential when switching from high-rate to middle-rate or from middle-rate to low-rate. It is required to install a speed-measuring motor on each low-rate motor to gain a proportionate signal with driving speed. Before synchronized rotate speed is reached, the control system will harmonize and control to prevent low-rate motor switches on.
