Finished product hopper: clean the cylinder of the sticky substance in the hopper, check and fill the oil cup in the air supply pipeline, and discharge the accumulated water in the oil-water separator.
The protective doors of each distribution box are well closed to remove dust; check and clean tools and lock them; improve the environmental sanitation of tool room and electrical room
2. Weighing system:
Check the cylinder, gas circuit leakage, oil level in the oil cup, water in the separator and deal with it; check and deal with the leakage of the admixture, water pipeline, and discharge port of the measuring hopper; check the stop position of the admixture throttling tank; each sensor and circuit inspection; inspection and treatment of hopper dust cover, soft joint and arch breaking device; check whether there are sundries in the hopper and clean it up; the admixture in the admixture bucket is cleaned every shift
3. Receiving system:
Rotary distributor: check the operation of the motor and the reducer; check the flexibility and reliability of the limit switch; the condition of the chute and the upper hopper and the cleaning of the adhesion; clean the dust on the motor and the reducer cover; maintain each lubrication point
High-level cement silo: the airtightness of the silo body and the airtightness of each sub-silo
Storage silo: Check whether the cylinder action and valve opening are normal; check and troubleshoot the air supply pipeline, add oil to the lubricating cylinder oil cup and discharge the accumulated water; check the action of the cement butterfly valve; check the leakage of the water supply system. The damage of each protective plate and cover; clean the dust of the distribution box
4. Mechanical room:
Check the fan load, temperature rise, belt tension; lubricate the shaft end bearing of the fan and feeder; check the lubricating oil level of the fan and the reducer of the feeder, add or replace it as required; clean the fan filter; check the bottom of the cement silo Check whether the gate valve and powder conveying pipeline are leaking and clean; check the flexible action of each pneumatic valve and solenoid valve; clean the power control panel; clean the dust and debris on the motor chain protective cover; the working condition of each arch breaker
Air compressor: Check the air compressor for over-temperature stop or failure prompts and deal with it in time; check the motor belt and its tension; regularly clean the air filter of the air compressor; regularly check the oil level of the air compressor lubricating oil; Drain the condensed water in the air receiver, cold dryer, oil-water separator
5. Feeding system:
Aggregate conveying equipment: check the operation of the belt and the interface; check the cylinder action of each feeding port and the opening and closing of the bucket door; check the operation of the belt idler; check whether the motor operation and temperature rise are normal; regularly check the oil level of the driving drum; Airtight, oil cup oil level and drainage; check whether the flow sensor is normal; clean the reversing and tensioning wheel adhesions every shift; power supply lines and lighting conditions; adjustment of the belt conveyor head scraper; adjustment of the belt cleaner ; Check whether the positioning screw of the driving drum and the oiling screw are loose; whether the sprinkler works abnormally; the wear degree of the hopper in the transfer station and the cleaning of the adhesion; oil filling at each lubricating point
The operation of the motor and the water pump; the leakage of the water pipe valve; check the liquid level of the oil chamber of the pump, and add it immediately if it is insufficient; check the liquid level of the pool at any time, and replenish it in time if it is insufficient;
6. Admixture equipment:
Leakage of pipelines and valves; operation of admixture pump.
