Automatic dosing syringe for veterinary use - 2 ml 獸醫(yī)連續(xù)注射器2毫升
This new - style automatic dosing system has achieved good economical and environmental benefits since it is put into practice in no . 2 water plant of chengtu water supply co 這種新型的藥液自動配投系統(tǒng)在成都市自來水總公司二廠投入運(yùn)行以來,取得了良好的經(jīng)濟(jì)和社會效益。
The technology of automatic dosing production line for welding rod shell is an important means to raise productivity , improve accuracy of mixture , reduce the cost and raise the level of civilized manufacture and environmental protection 電焊條藥皮涂料自動配料生產(chǎn)線技術(shù),是提高生產(chǎn)率和配料精度,降低生產(chǎn)成本,提高文明生產(chǎn)水平和環(huán)境保護(hù)水平的重要手段。
For a long time , many problems arising in the process of manufacturing , such as the blocking of the raw material flow , can not be solved properly , which seriously restrict the technology development of automatic dosing production line in china 長期以來,因生產(chǎn)過程中物料流系統(tǒng)的堵塞或者流通不暢等問題未能得到很好地解決,嚴(yán)重制約了我國電焊條藥皮涂料自動配料成套生產(chǎn)線技術(shù)的發(fā)展。
Through research of automatic dosing system , established by determining automatic dosage in the methods of transmittance pulsation , streaming potential and mathematical model , it can be concluded that the automatic dosing system brought forward in this paper can fulfill requirements of the technics . likely , this system can also be applied for dosing of other chemicals in water plants , chemical dosing of wastewater treatment plants and other similar places 通過對采用透光率脈動、流動電位、數(shù)學(xué)模型等方法確定混凝劑投加量建立的自動配投系統(tǒng)的研究表明本文提出的自動配投系統(tǒng)能滿足工藝的要求:同樣該系統(tǒng)也適用于給水處理廠其他藥劑的投加,適用于污水處理廠及其他類似場合藥劑的投加。
By using inorganic polymer coagulant and automatic dosing method , very good treatment results were obtained . in addition , experiments were conducted on the pre - treatment of source water using kmno4 , and very good results were gained . this thesis also did relevant research on the effects of enhanced pre - treatment for organic removal 還進(jìn)行了試驗(yàn)室靜態(tài)試驗(yàn),考察了高錳酸鉀復(fù)合藥劑用于化學(xué)預(yù)氧化的處理效果,試驗(yàn)結(jié)果表明,高錳酸鉀復(fù)合藥劑具有優(yōu)越的強(qiáng)化混凝作用,有助于去除濁度、色度功能,并能降低混凝劑用量。
