sand disk 中文意思是什麼
sand disk
解釋
拋光圓盤-
Sluice gate of double disk is controlled by electric - hydraulic handspike ; plc will compare sand temperature on outlet according to pre - designed value and inner sand temperature of double disk ; and then it adjusts close time of sluice gate, controls residence time of hot sand in double disk ; therefore, it can control sand temperature of outlet and make it reach required value.
雙盤的卸砂門由電液推桿控制， plc根據預設的出口砂溫與實測的雙盤內砂溫進行對比，而調整卸砂門的關閉時間，控制熱砂在雙盤內的停留時間，進而控制雙盤出口砂溫使其達到要求。 -
This control system adopts creditable plc for real control ; it sends many simulating signals collected by old sand temperature of inlet, suction opening temperature of double disk, inner sand temperature of double disk, current of mainframe and current of fan ; meanwhile, the operation signal and switching value signal outputted by material movement transducer is inputted to switching value module of plc ; it gets evidence of water feeding after cpu account ; the operation result of cpu is outputted by switching value of plc to control unlock combination of coarse, middle and thin water feeding electromagnetically operated valve and then gets different water feeding quantity
該控制系統採用高可靠性的plc可編程序控制器進行實時控制，傳感器所採集的入口舊砂溫度雙盤抽風口溫度雙盤內砂溫主電機電流及鼓風機電流等模擬量信號直接輸入plc的模擬量採集模塊，同時加砂設備運轉信號及加砂設備物料移動檢測傳感器發出的開關量信號輸入plc的開關量模塊，由cpu獲取經運算而得到加水計算依據， cpu運算結果直接由plc的開關量輸出控制粗中細加水電磁閥的開啟組合，而得到不同的加水量。 -
When wind pressure of fan is deficiency or the inner sand layer of double disk is too thick, the tuyere of double disk will jam especially when moisture of sand is too high ; this jam must be treated by manually because the jam of green sand becomes very hard after air - dry and the system can not renew by itself
當鼓風機的風壓不足或雙盤內砂層過厚，雙盤內風口會出現堵塞現象，尤其是砂子水分過高這種堵塞除非人工清理，其系統本身是無法恢復的，因為濕的砂子堵塞進風口乾后會非常堅硬。 -
It can make sprinkler of water feeding install on strap or on sand inlet of double disk and adjust spraying angle of sprinkler according to real condition ; the water will spray on falling sand that makes it form sand curtain ; it sprays water on hot sand equably and extends exchanging time of water and hot sand. 4
根據現場情況，加水噴頭可設在進砂皮帶上，或設在雙盤的進砂口處，調整噴頭的噴灑角度，使水噴向由下落的砂子組成的砂簾，將水盡可能預先均勻得噴灑在熱砂上，增加水與熱砂的有效熱交換時間。 -
Discharge - sand gate offers double disk cooling system creditable condition for low temperature ; when sand temperature is very high, it can change the way of discharge - sand gate into intermittent type : put rating sand to double disk and spray water for falling temperature until temperature falls designed range ; open the discharge - sand gate and discharge sand ; and then takes anther cycle ; this type has good effect after real testing, which is the effective way for exerting cooling function of double disk
卸砂門這種控制方式給雙盤冷卻系統的可靠降溫提供了條件，當型砂溫度較高時可將卸砂門改成間歇式的，先將雙盤內加入給定的砂量，噴水后直到溫度降到給定的范圍后，卸砂門打開將砂子卸出，然後進行下一循環，這一方式經實際運行驗證效果良好，是充分發揮雙盤冷卻作用的有效途徑。 -
The system controls water - spraying quantity through measuring old sand temperature and current of double disk engine, which makes old sand have low temperature and average moisture after cooling
系統是通過檢測舊砂的溫度以及雙盤電機電流來控制噴水量，使經過冷卻后的舊砂溫度低水分穩定均勻。 -
Double disk stir cooler can accelerate evaporating moisture for getting low temperature with strong stirring of scraper in short time through water feeding, blast and convulsions ; meanwhile, it has definite function of rebirth and mixing for old sand, which makes it become the best device for old sand treatment of clay sand system
雙盤攪拌冷卻機，能在短時間內在刮板的強烈攪拌下，通過加水鼓風抽風，促使水分蒸發以達到降溫的目的，同時對舊砂有一定的再生混勻作用，使其成為對粘土砂系統舊砂進行冷卻的最佳裝置之一。 -
2. there are three measuring positions for temperature transducer : inner sand temperature of double disk cooler ; testing sand temperature near feeding hopper can reflect low temperature condition of old sand ; the temperature of double disk cooler top can reflect inner temperature change of double disk ; therefore, it can estimate temperature change according to this change
2溫度傳感器的測量位置有三處： 1雙盤冷卻器內部砂溫2進料口附近檢測砂溫，能夠反饋舊砂降溫情況3雙盤冷卻器頂部抽風口氣溫，反映雙盤內氣溫變化情況，由此氣溫可大致判斷雙盤內砂溫變化情況。 -
The following is discharge - sand gate picture of water spray cooling control system of double disk cooling machine in laidong offered by our company
