2XZ真空泵操作須知 1.查看油位,以停泵時注油至油標中心為宜。過低對排氣閥不能起油封作用,影響真空度。過高,可能會引起通大氣起動時噴油。運轉(zhuǎn)時,油位有所升高,屬正常現(xiàn)象。油采 用規(guī)定牌號的清潔真空泵油,從加油孔加入。加油畢后,應旋一上螺塞。油宜經(jīng)過濾,以免雜物進入,堵塞油孔。 2.2XZ型旋片式真空泵可在通大氣或任何真空度下一次起動。泵口如裝接電磁閥,應與泵同時動作。 3.環(huán)境溫度過高時,油的溫度升高,粘度下降,飽和蒸汽壓會增大,會引起極限真空有所下降,特別是用熱偶計測得的全壓強。如加強通風散熱,或改善泵油性能,極限真空可得到改善。 4.檢查2XZ型旋片式真空泵的極限真空以壓縮式水銀真空計為準,如計經(jīng)充分預抽校驗,泵溫達到穩(wěn)定,泵口與計直接接通,運轉(zhuǎn)30分鐘內(nèi),將達到極限真空。總壓強計測得之值與泵油和真空計、規(guī)管誤差有關,有時誤差甚至可很大,只能作參考。 5.如相對濕度較高,或被抽氣體含較多可凝性蒸汽,接通被抽容器后,宜打開氣鎮(zhèn)閥,運轉(zhuǎn)20~40分鐘后關閉氣鎮(zhèn)閥。停泵前,可開氣鎮(zhèn)閥空載運動30分鐘,以延長泵油壽命。 6.2XZ型旋片式真空泵用油選擇:泵油的粘度影響起動功率和泵的極限真空,粘度高時對真空度有利,起動功率則大一些。油在泵溫下的飽和蒸汽壓則會影響泵的極限總壓強,越低越好。高速真空泵油和3#擴散泵油的粘度較1號真空泵油大,飽和蒸汽壓較1號真空泵油低,但3#擴散泵油價格較高。具體選什么油,可根據(jù)上述介紹結合具體使用要求來選擇。 1一般情況下,凡希望總壓強在6X10-2帕以上的應用上海產(chǎn)的高速真空泵油。4升/秒以下小泵也可用1號真空油泵代,8升/秒以上直聯(lián)泵可用3#擴散泵油代。 2如果對真空度要求不高,且油的污染更換頻繁,真空泵油供應困難,可采用50號機械油代替。 3如果環(huán)境溫度低,起動困難,極限真空要求不高,可采用粘度較上略低的真宅泵油或機械油。 旋片式真空泵性能參數(shù) 型號 2XZ-0.25真空泵 2XZ-0.5真空泵 2XZ-1真空泵 2XZ-2真空泵 2XZ-4真空泵 2XZ-8真空泵

A, the door installation: 1, the door assembly connection, should be strict, level off, without black seam; Fixed parts should lock; Within 2 meters door cover diagonal should be accurate, allow the tolerance of 1 mm or less, more than 2 meters allow 1.5 mm or less; 2, door sets, should be vertical, three-dimensional horizontal straightness tolerance + 2 mm, horizontal straightness tolerance allowed + 1 mm; Gap between the door and the wall with foamed double-sided sealing glue, plastic foam should be painted, dry cutting is flat and level. Second, the set of installation: 1, line installation should be uniform coating and door cover, wall body is fixed, set the line outlet should level off, close, no crack, installed on the same side of line in a plane; Because wall is at ordinary times, must ensure that the set of flat line interface. Set of camber line allowed tolerance of 1 mm. Set of line with walling crack sealant caulking processing. Three, door leaf installation: 1, the door leaf after installation, should level off, vertical, doors and door cover exposed faces flat; Doors open the same ring, switch freely; 2, gap between the door and the door leaf, the seam for 6 to 8 mm, the rest of the trilateral to 3 mm; All gap tolerance + 0.5 mm; Article 3, after the doors locked and sealed tightly bound, and does not wobble. 4, hardware: 1, the door hinge should be vertical and flat; The flat hinge should be on doors and door cover corresponding to the slot, the slot should be specifications, size the same as the hinge, the trilateral allowable tolerance + 0.5, after fit up flat without aperture, should be flexible hinge open freely. Trigeminal hinge according to the mold installation, bolt should be put in place. Hinge fixed screws should be packed full, straight, hidden in the hinge plane. 2, lock slot should be accurate, specifications, size is consistent with the lock body, lock plate; Door locks installed should be tightened, the lock is ringing; Accessories installation is complete, the fixed screw shall be entirely flat. 3, suck, door closer, handle, etc shall be installed in the specified location, installation is firm, fixed bolts shall be installed, straight, installed after the fitting effect is good. Five, the appearance: 1, cover, door line combined with ground gap should be less than 3 mm, with waterproof sealant sealing slit. 2 has grown two millimeters, the door is installed, must be smooth uniform, open and flexible, the overall effect is good, no scratches.
