The reason is sticky resin sand exploded about 500 ° C, the resin sand removal, mold gap increases and loss of feeling, sticky liquid iron sand to form a preventive measure) increased core compactness 2) thick at the original sand can be used as a special zirconium sand and cold welding iron ore, etc. 3) brush fire-resistant coating and appropriate to reduce the pouring temperature 4) type suitable furan resin. Dust ①, pay attention to the fan when rapping or blowback precipitator ash rapping open when the motor and the motor can not start cleaning, or affect the discharge of dust effects. Time visualization dust content may be. ②, pulse dust collector attention must be manually cleaning the class. ③, joins situation every week to check the bag to prevent excessive dust bag off row. ④, when the dust of work prohibited to use welding equipment in the production line, or easily inhaled Mars burn bag. ⑤, air volume control valve timing checked regularly to prevent loosening after matching unreasonable amount of wind influence the effect of dust. ⑥, dust is likely to use the pipeline for many years at the bottom of the pipe dust accumulation effect of dust affect the price of resin sand production line, such as replacement of the workshop increased dust bag and no significant improvement, it is recommended to clean the pipe. 1.2.1 Daily inspection class must shakeout machine, vibrating conveyors, crushers, vibrating feeder, sand separators and other equipment cooling vibration motor bolt check and tighten again. 1.2.2 weekly vibrating conveyor, crusher, vibrating feeder and other equipment rubber spring inspections, identify problems in time. 1.2.3 class must check bucket elevator chain working conditions, tape tension situation, the tightness of the belt resin sand production line equipment, observe the hopper, feed rate, etc., identify problems promptly. 1.2.4 checked weekly throttle ring bore, wear rings, the fixed ring wear on the rotor resin sand production line, the tightness of the V-belt check and found the problem promptly. 1.2.5 class of solenoid valves, check valves and other pneumatic components; clean air filter water, oil mist when the oil level is lower than offline, should promptly fill oil. 1.2.6 gas tank, oil-water separators, each booster tank sewage drain valve once a week. 1.2.7 shaker screens, crushers screen checked 1-2 times a day, was found damaged promptly replaced. Note 1.2.8 class gas delivery pipeline is sending sand ran or whether tainted sand phenomenon, ran and found sand drain phenomenon in time to find the cause of casting resin sand production line _ Qingdao Heng (certified) _ resin sand production line by Heng Machinery Co., Ltd.
