博莱特螺杆空压机进气阀/空压机卸荷阀/空压机入气阀/的工作原理:
①启动。电机启动,主机开始运转,进气阀关闭状态,阀芯上的小空进气。经过压缩的油气进人油气桶,系统压力逐沂上升,稳定到3-3.5bar。
②加载。电机星三角转换,控制系统.(压力开关)会比较系统的实际压力与设定压力,当系统压力低于压力开关设定下按犍压力时,压力开关动作使加载电磁阀(三向电磁阀)加电三向电磁阀开启,向进气门伺服汽缸供气推动控制气缸打开蝶阀,进气阀全开吸气;经由电磁阀的压力同时关闭泄放阀,机器不再放空,罐内压力持续上升至顶开最小压力阀向外供气。加载出现小问题:螺杆空压机机无法加载
③卸载。当压力上升到压差开关上限压力时,压差开关发出一个电信号给三向电磁阀,电磁阀关闭停止向进气门伺服气缸供气,控制气缸不受压则蝶阀关闭维持小孔进气,此时受配重控制止回阀能及时迅速的紧密关闭,同时泄放阀打开释放油气桶内压力至基本油压。空压机处于空载运行,在加载电磁阀连续失电20min后,系统进入空车过久停车状态。卸载小问题:螺杆空压机无法卸载
④容调。空压机加载过程中为减少空压机的空重负荷次擞,安装有反比例阀,当机组压力达到压力开关上限前反比例阀提前动作.减少向伺服汽缸的供气量,进气阀伺服气缸阀杆推力减少,在弹簧力的作用下阀杆回缩,当弹簧力与气缸的气体推力平衡时阀杆处于半开状态,进气量减少实现空压机的容量调节。
⑤停机。停机信号来自空车过久或系统压力长时间处于压力上限,电机停止,主机停转不再吸气,进气阀的内部止回阀迅速关闭确保没有停机吐油的现象,泄放阀持续放空至外部大气压力。规格型号如下:1622171380,1622515580,1622075800,1622377800,1613815000,1622878680,1622075880,1614900800,1622878682,1623079484,1613900800/1622353900,1613900800,1614900880,1613679300,1622098380,1622316282,1202644280,1613756885,1613814484,1621171203,1622377882,1623178680,2102060400,2102080400,2202260953,2235154200,2901046301,2906600600,2906601300,8204093010,1622075880,,1901062072,2910305700,1901071052,1604621781,2903000301,1614925880,1202667500,2252550293,1614648780,2252550290,1614900883,1901002715,1615766785,1901003397,1901055302,1901008407,1901060473,1614700580,1622364800,1613900800,1622353984,1622878682,16228786871622351300,1622171305,1622878682,1622171305,1622171380,1613756884,1622316290,1622364880,1622515580,2901044800,1622075900,1622515570,1622075800,1622364800,1622264880,1622377800,1622316200,1613815000,1622878680,1622075880,1614900800,1614900883 ,1614900802,1614900801,1614900800,1622878682,1613900885,1613900800,1622353980,1622353900,2901000201,1613900885,1613900800,1622353980,1622353900,1622351380,1622353984,1622353900,1622878604,1900952681,1614900880,1613679300,1622878687,1622171300,1622171380,1622316285,1613814400,1613814484,1613681801,1613815000,1626105280,2252550289,2910300300,1623079481,1622075880,1625165322 ,1625165300 ,1625165301,1613756884 ,1622878682,1622878687 ,1625165325,1625165302,1622515680 ,1625165303 ,1613814484 ,1622515580,1622348800,1622348880,1622348800,1622348980,1614900883 ,1623079484,1621129981 ,1611672590 ,1623079484 ,1625170437 ,1625170438,1625170439
