A4VSO泵具有泵具有噪音低、體積小、自吸能力好、可靠性高等優(yōu)點(diǎn)。在閉式系統(tǒng)上應(yīng)用,油泵變量過(guò)零位時(shí)一般柱塞泵都有托盤現(xiàn)象,唯獨(dú)D-A4VSO泵有效解決此類問題,因補(bǔ)油泵、控制泵可以串接、控制閥可以集成在泵蓋上,其結(jié)構(gòu)非常緊湊;另外,比例泵均帶有位移傳感器閉式反饋回路,其零位控制精度非常高。廣泛應(yīng)用于:冶金行業(yè)、鍛壓行業(yè)、船舶行業(yè)、船舶等等領(lǐng)域。A4VSO系列規(guī)格有40、71、125、180、250:;變量形式有恒壓,恒功率、液動(dòng)、負(fù)載感應(yīng)、比例、伺服、壓力流量復(fù)合控制形式;有開式系統(tǒng)泵和閉式系統(tǒng)泵。A10-FR01B-12,A10-FR01C-12,A10-FR01H-12,

為什么會(huì)結(jié)霜與結(jié)霜機(jī)理;首先明確,結(jié)霜是發(fā)生在制冷系統(tǒng)蒸發(fā)器,而且是風(fēng)冷式蒸發(fā)器;當(dāng)環(huán)境溫度比較低的時(shí)候(比如低于度),此時(shí)蒸發(fā)測(cè)的蒸發(fā)溫度比較低(我們按照℃環(huán)境來(lái)說(shuō),蒸發(fā)溫度就接近-15℃甚至更低);我們可以認(rèn)為蒸發(fā)器中部位置銅管的溫度近似等于蒸發(fā)溫度,那么銅管的溫度在-15℃左右,此時(shí)空氣中如果有水蒸汽,那么空氣中的水蒸氣遇到低溫翅片(銅管),必然后凝結(jié)成固態(tài)的小冰晶,久而久之,蒸發(fā)器就結(jié)霜了;當(dāng)然并不是溫度越低越容易結(jié)霜,一般在制冷行業(yè)測(cè)試領(lǐng)域,干球/濕球=2/1的時(shí)候是結(jié)霜工況,或者干球/濕球=/的時(shí)候是重度結(jié)霜工況;此時(shí)機(jī)組的結(jié)霜是zui明顯也zui容易的;為什么這個(gè)工況容易結(jié)霜?因?yàn)榇藭r(shí)空氣中的濕度zui大,水蒸氣含量是zui高的;在低溫工況下,比如-15℃以下此時(shí)空氣中的相對(duì)濕度反而低,所以結(jié)霜反而不是很嚴(yán)重。
