進口防爆電磁閥|進口防爆電磁閥【進口防爆電磁閥】優(yōu)點：
Imports explosion-proof solenoid valve | imports of explosion-proof solenoid valve【Import proof solenoid valve】 advantages:
1、防爆電磁閥工作壽命長。
explosion-proof solenoid valve long working life.
2、防爆電磁閥工作制式：分*工作制，反復短時工作制和短時工作制三種。防爆電磁閥均為*工作制，即線圈允許*通電工作。對于長時間閥門開通只有短時關閉的情況，則宜選用常開電磁閥。用在短時工作制而批量又很大時，可作特殊訂貨以降低功耗。
Explosion-proof solenoid valve working standard: points of long-term work, repeated short-time work and short-time working system of three. Proof solenoid valves are long-term work system, that coil to allow long-term power. For a long time the valve opening only short-term closure, you should use normal open solenoid valve. In short-time work in large quantities when you can make a special order to reduce power consumption.
3、防爆電磁閥工作頻率：動作頻率要求高時，結構應優(yōu)選直動式電磁閥，電源聽優(yōu)選交流。
The explosion-proof solenoid valve operating frequency: the frequency of demanding action, the structure should preferably direct acting solenoid valve, the power to listen to the exchange preferred.
進口防爆電磁閥概述：
Overview of imports explosion-proof solenoid valve
進口防爆電磁閥適用于易燃易爆介質(zhì)，以及對爆炸性危險場所管路介質(zhì)的自動切換。如天然氣、煤氣、液化氣等氣體或其它流體。隔爆型防爆形式是一種具有隔爆外殼的電氣設備。進口防爆電磁閥隔爆外殼能承受已進入外殼內(nèi)部的可燃性混合物內(nèi)部爆炸而不損壞，并且通過外殼上的任何接合面或結構孔不會引燃一種或多種氣體或蒸氣所形成的外部爆炸性環(huán)境的電氣設備。進口防爆電磁閥有兩種形式，一種是常閉式，常閉：當線圈通電時，電磁鐵芯吸合，卸壓孔打開，主活塞由介質(zhì)壓力推動，打開主閥口，介質(zhì)流通。一種常開式，當線圈通電時，電磁鐵芯吸合，卸壓孔關閉，主活塞由介質(zhì)壓力推動，關閉主閥口，介質(zhì)截止。
Import proof solenoid valves are suitable for inflammable and explosive medium, and automatically switch on the explosive hazardous locations pipeline media. Such as natural gas, coal gas, liquefied gas or other fluid. The explosion-proof form of a flameproof enclosures of electrical equipment. The imported proof solenoid valve flameproof enclosure can withstand an internal explosion of the combustible mixture to enter the interior of the housing without damage, and through any joints or structural holes in the housing does not ignite one or more gases or vapors formed by the external electrical equipment for explosive environments. Imports of explosion-proof solenoid valve has two forms, one is normally closed and normally closed: when the coil is energized, the electromagnet core pull, pressure relief hole to open the main piston driven by medium pressure, open the main valve port, media circulation. A normally open when the coil is energized, the electromagnet core pull relief hole is closed, the main piston driven by medium pressure, turn off the main valve port, media cutoff.
進口防爆電磁閥故障排除：
Imports explosion-proof solenoid valve troubleshooting:
一、電磁閥通電后不工作 Solenoid valve is energized not working
檢查電源接線是否不良→重新接線和接插件的連接 檢查電源電壓是否在±工作范圍-→調(diào)致正常位置范圍 線圈是否脫焊→重新焊接 線圈短路→更換線圈 工作壓差是否不合適→調(diào)整壓差→或更換相稱的電磁閥 流體溫度過高→更換相稱的電磁閥 有雜質(zhì)使電磁閥的主閥芯和動鐵芯卡死→進行清洗,如有密封損壞應更換密封并安裝過濾器 液體粘度太大，頻率太高和壽命已到→更換產(chǎn)品
Check power wiring is bad → re-wiring and connectors connected Check power supply voltage operating range is within ± - → tone range coil to the normal position Desoldering → ??re-welded coil short circuit → Replace the coil operating pressure differential is inappropriate → adjust the differential pressuresolenoid valve fluid temperature is too high →→ or replace commensurate replace the solenoid valve commensurate impurities so that the main spool of the solenoid valve and movable core stuck → cleaning, if the seal is broken should replace the seal and install filter liquid viscosity is tootoo often, and life has to → replacement products
二、電磁閥不能關閉 Solenoid valve can not be closed
主閥芯或鐵動芯的密封件已損壞→更換密封件 流體溫度、粘度是否過高→更換對口的電磁閥 有雜質(zhì)進入電磁閥產(chǎn)閥芯或動鐵芯→進行清洗 彈簧壽命已到或變形→更換 節(jié)流孔平衡孔堵塞→及時清洗 工作頻率太高或壽命已到→改選產(chǎn)品或更新產(chǎn)品
The seals of the main spool or iron moving core damage → Replace the seal fluid temperature, the viscosity is too high → impurities into the solenoid valve production spool or moving core → replacement the counterparts of electromagnetic valve cleaning spring life or deformation→ Replace the throttle the Kong Pingheng the holes clogged → timely cleaning too often or life to the → reelection products or updated product
三、其它情況 Other cases
內(nèi)泄漏→檢查密封件是否損壞,彈簧是否裝配不良 外泄漏→連接處松動或密封件已壞→緊螺絲或更換密封件 通電時有噪聲→頭子上堅固件松動，擰緊。電壓波動不在允許范圍內(nèi)，調(diào)整好電壓。鐵芯吸合面雜質(zhì)或不平，及時清洗或更換。
Internal leakage → Check the seals for damage, spring assembly adverse external leakage → connections loose or the seal has been broken → screws or replace the seal energized the noise → chieftain sturdy pieces loose, tighten. Voltage fluctuation is not within the allowable range, adjust the voltage. Core pull the occlusal surface impurities or uneven, timely cleaning or replacement.
