脫粒損失 的英文怎麼說
中文拼音 [tuōlìsǔnshī]
脫粒損失
英文
threshing losses-
The air - flow field in the stripping unit can be adjusted easy by changing the rotation speed of fan which is benefit to reduce the grain losses, it was found during experiment that the cross - flow fan can diffuse some of mog ( material other of grain ) and diffuse it in a certain direction which is useful to satisfy the working condition for driver and lighten working load of the threshing unit of the combine harvester candidate and speciality : peng shengmin ; machinary design and theory supervisor : prof. zhang huiyou
該裝置可以通過控制橫流風機的轉速，使裝置內氣流在有控制的情況下排出裝置外，改善了裝置內流場狀態，提高了裝置喂入口處的負壓，這對減少摘脫裝置的落粒損失，有著重要意義。由於橫流風機的除雜，可以減輕機器的復脫和清選負荷。安裝橫流風機后可以對裝置的出風口處灰塵進行有效導引，改善駕駛員的工作條件。A stripping uint with the cross - flow fan was developed, aimed to reduce the grain losses at the rear of the stripping drum reduce the blocking to the air outlet sifter and diffuse dust. this dissertation gives overall scheme of the rig and had mad experimental study
針對非氣吸式割前摘脫裝置在收獲作物時，出風口篩面發生堵塞使裝置內流場變差，導致裝置的落粒損失率過大；以及出風口處煙塵四散，影響了駕駛員的視野和危害工作人員的身心健康等生產中存在的問題。Its field trial showed that the free grain loss is reduced and sp ecially invented windrowing device closely behind the stripping rotor located ju stified itself by the clear cutting with shorter stubble and being center - deliv ered windrow of the straw
田間試驗表明落粒損失減少，作者發明的設置於摘脫流通筒後面的切割摟集裝置工作性能良好：割茬低條鋪放在兩履帶之間。Cylinder loss and damage can be prevented by careful checking of the condition of the harvested beans and varying the cylinder speed accordingly.
脫粒滾筒造成的損失危害，可以通過仔細檢查收獲豆子的情況和相應地改變脫粒滾筒的速度來防止。Stripper header invented by afrc uk, mounted on grain combine harvester showed its two deficiencies in china : leaving the stripped straw stan ding without windrowing and relatively high free grain loss especially working a t lower ground speed
英國發明的懸掛在聯收機上的摘脫臺在中國使用中有兩個缺點：摘脫后的基稈未能切割摟集成條鋪和落粒損失，尤其在低速時較大。Abstract : stripper header invented by afrc uk, mounted on grain combine harvester showed its two deficiencies in china : leaving the stripped straw stan ding without windrowing and relatively high free grain loss especially working a t lower ground speed
文摘:英國發明的懸掛在聯收機上的摘脫臺在中國使用中有兩個缺點：摘脫后的基稈未能切割摟集成條鋪和落粒損失，尤其在低速時較大。Through the experimental analysis of the single factor, the influence of the rotation speed of the two kinds cross - flow fan and the forward speed was find on grain losses of the unit, finally the optimum combination of the forward speed and the rotation speed was got
通過單因素的實驗分析，找出在橫流風機不同風機轉速，不同的行車速度下摘脫裝置落粒損失的變化規律，並確定了最佳的裝置參數組合。The conclusion indicated that the effect of flexible pole tooth on threshing was better compared to rigid teeth ' s, since production efficiency was increased and the damage rate was reduced distinctly, furthermore, the un - threshed rate, impurity and power take - off frequency gotten were decreased
結果表明，相對其他脫粒齒而言，柔性桿齒質量輕，種子破碎率顯著降低，未脫凈損失減少，含雜率降低，發芽率高。The mechanism of arc eroding for cuw60 / crcu integrated contact is the volatilization of cu under the arc working, then the particles of w were worn off the matrix, this phenomena is n ' t formed continuous skeleton during the connecting and cutting. such - and - such repeating resulted in the arc erosion of the contact, until invalidation
（ 1 ） cuw60觸頭的燒損機理是以cu首先熔化噴濺，然後沒有形成連續骨架的w顆粒在關合的磨損中脫落，這是一個燒損周期，如此的循環導致觸頭的燒損，直至失效。分享友人
