選型時(shí)需要注意PARKER電磁閥介質(zhì)特性 質(zhì)氣,液態(tài)或混合狀態(tài)分別選用不同品種的電磁閥;介質(zhì)溫度不同規(guī)格產(chǎn)品,否則PARKER電磁閥線圈會(huì)燒掉,密封件老化,嚴(yán)重影響壽命命; 介質(zhì)粘度,通常在50cSt以下。若超過(guò)此值,通徑大于15mm時(shí),用多功能電磁閥;通徑小于15mm時(shí),用高粘度電磁閥。
介質(zhì)清潔度不高時(shí)都應(yīng)在電磁閥前配裝反沖過(guò)濾閥,壓力低時(shí),可選用直動(dòng)膜片式電磁閥;
PARKER電磁閥型號(hào)有: PHS530S-10-220V-D PHS530E 3位中位排氣 PHS530S-10-110V PHS530S-10-24V PHS530S-10-220V PHS540S 2位單電控 PHS540S-10-24V-DL PHS540S-10-220V-DL PHS540S-10-110V-D-L PHS530D 2位雙電控 PHS540S-10-220V-D-L PHS541S-10-24V-DL-L PHS541S-10-220V-DL-L
美國(guó)原裝PARKER電磁閥介質(zhì)若是定向流通,且不允許倒流,需用雙向流通;
介質(zhì)溫度應(yīng)選在電磁閥允許范圍之內(nèi)。
