隔膜壓力表
diaphragm pressure gauge
用途 use
隔膜壓力表用于化工等部門生產(chǎn)過程中測量具有腐蝕性、高粘度、易結晶、含有固體狀顆粒、溫度較高的液體介質(zhì)的壓力。
applicable to lpressure measurements for liquid mediums at high temperature,such as corrosive ,high viscous ,crystallizable and solid-particles containing fluids commonly used in petrochemical indusery,etc.
安裝與使用
1. 儀表在安裝前應檢查儀表示值是否在零位。
2. 儀表的膜片隔離器與壓力表不得拆卸或更換別種壓力表，以免內(nèi)部填充的工作液外泄，而影響使用性能。
3. 用戶應按被測介質(zhì)的性質(zhì)來選擇合適的接口型式，膜片材料和墊片材料。用于有較強機械震動和介質(zhì)壓力脈沖的場合，要求配用耐震型壓力表。
4. 為適應某些特殊介質(zhì)的耐蝕性，應在與被 介質(zhì)接觸處加裝保護膜。
5. 儀表上的壓力表安裝位置和注意事項均與普通壓力表相同。
1. check if the indicating value is lf nzero-position on the gauge dial before fitting .
2. don’t dismantle the diaphragm separator from gauge arbitrarily or replace with other gauges to avoid any leakage of working liquid and frrther to avoid any adverse effect on gauge’s operational performance.
3. se-lect appropriay the joint or connection mode according to the propery of the medium to be measured,as well as materials for diaphragm and gaslet to be chosen.damping-type gauge will be required in case there is a strong shock or impuklsive pressure of medium.
4. when some mediums with very strong corrosivity are measured,a protective film should be used at the contact point of the medisdum to be measured.
5. the postion for fitting-up this kind of gauge and what to be dine with care are the same as verdsatile gdauges.
