軟管泵性能<br />
軟管泵性能的兩個主要參數(shù)為排量和壓力。排量以每分鐘排出若干升計算?它與鉆孔直徑及所要求的沖洗液自孔底上返速度有關(guān)，即孔徑越大，所需排量越大。要求沖洗液的上返速度能夠把鉆頭切削下來的巖屑?巖粉及時沖離孔底，并可靠地攜帶到地表。地質(zhì)巖心鉆探時一般上返速度在0.4～1米/分左右。<br />泵的壓力大小取決于鉆孔的深淺沖洗液所經(jīng)過的通道的阻力以及所輸送沖洗液的性質(zhì)等。鉆孔越深管路阻力越大、需要的壓力越高。隨著鉆孔直徑，深度的變化，要求泵的排量也能隨時加以調(diào)節(jié)。在泵的機構(gòu)中設(shè)有變速箱或以液壓馬達(dá)調(diào)節(jié)其速度、以達(dá)到改變排量的目的。為了確掌握泵的壓力和排量的變化軟管泵上要安裝流量計和壓力表，隨時使鉆探人員，解泵的運轉(zhuǎn)情況同時通過壓力變化判別孔內(nèi)狀況是否正常以發(fā)生孔內(nèi)事故。！

軟管泵用途非常廣泛，市面上的諸多場合均可適用，如：污水泵井事故清空，污水泵站事故抽空，水廠的污水池、污泥池清空。市政下水道系統(tǒng)的污水、污泥清空抽排。工廠、罐車事故后的油品、液體物質(zhì)、化學(xué)污泥等的緊急轉(zhuǎn)移；事故后地表沖洗水抽吸泵。消防應(yīng)急水轉(zhuǎn)移；緊急供水泵站，泵內(nèi)部過流部件都可配備不銹鋼，數(shù)臺泵車串聯(lián)使用可作為臨時供水泵站。軍隊、海軍部隊?wèi)?zhàn)備后勤泵車。

Hose pumps are very versatile and can be applied to many occasions on the market, such as: emptying of sewage pump wells, emptying of sewage pumping stations, emptying of sewage ponds and sludge ponds in water plants. Empty sewage and sludge from municipal sewer system. Emergency transfer of oil, liquid substances, chemical sludge, etc. after the accident at factories and tankers; suction pumps for flushing water on the surface after the accident. Fire emergency water transfer; emergency water supply pump station, the internal flow parts of the pump can be equipped with stainless steel, several pump trucks in series can be used as temporary water supply pump station. Military and naval forces combat readiness logistic pump truck.
