上海持承自動(dòng)化設(shè)備有限公司優(yōu)勢(shì)特價(jià)供應(yīng)TOPWORX 回訊開(kāi)關(guān)TXP-L2CGNPM000006217
閥門定位器按其結(jié)構(gòu)形式和工作原理可以分成氣動(dòng)閥門定位器、電-氣閥門定位器DVC-DNZ2BPS44參數(shù)及設(shè)置
閥門定位器能夠增大調(diào)節(jié)閥的輸出功率,減少調(diào)節(jié)信號(hào)的傳遞滯后的情況發(fā)生,加快閥桿的移動(dòng)速度,能夠提高閥門的線性度,克服閥桿的摩擦力并消除不平衡力的影響,從而保證調(diào)節(jié)閥的正確定位。銷售要經(jīng)驗(yàn)還是要學(xué)歷
一伙劫匪在搶銀行時(shí)說(shuō)了句至理名言:“通通不許動(dòng),錢是國(guó)家的,命是自己的!”劫匪回去后,其中一新來(lái)的碩士劫匪說(shuō),老大,我們趕快數(shù)一下?lián)屃硕嗌?,那老劫匪(小學(xué)文化)說(shuō):“你傻?。窟@么多,你要數(shù)到什么時(shí)候?今天晚上看新聞不就知道嗎?”
啟示:看來(lái)學(xué)歷只是敲門磚啊,經(jīng)驗(yàn)很重要,相信每一個(gè)成功的銷售都有類似的“土方”,類似的“經(jīng)驗(yàn)”啊。
