折彎機液壓系統的故障有:閥不能換向或換向動作緩慢,泄漏,電磁先導閥有故障等。
Bending machine hydraulic system faults are: valve can not change or change the slow action, leakage, electromagnetic pilot valve failure, etc..
(1)換向閥不能換向或換向動作緩慢,一般是因潤滑不良、彈簧被卡住或損壞、油污或雜質卡住滑動部門等原因引起的。對此,應先檢查油霧器的工作是否正常;潤滑油的粘度是否合適。而電路故障一般又分為控制電路故障和電磁線圈故障兩類。在檢查電路故障前,應先將換向閥的手動旋鈕滾動幾下,看換向閥在額定的氣壓下是否能正常換向,若能正常換向,則是電路有故障。此時,應更換密封圈、閥桿和閥座,或將換向閥換新。假如在額定電壓下換向閥不能正常換向,則應檢查電磁線圈的接頭(插頭)是否松動或接觸不實。檢查時,可用儀表丈量電磁線圈的電壓,看是否達到了額定電壓,假如電壓過低,應進一步檢查控制電路中的電源和相聯系關系的行程開關電路。
(2) for a long time after the use of the valve spool valve sealing ring wear, stem and valve seat damage phenomenon, resulting in leakage of the valve, the valve action is slow or not normal commutation failure. At this point, the sealing ring should be replaced, the stem and the valve seat, or to replace the valve.
(3)若電磁先導閥的進、排氣孔被油泥等雜物堵塞,封鎖不嚴,流動鐵芯被卡死,電路有故障等,均可導致換向閥不能正常換向。
(1) the reversing valve can not reverse or change the slow action, generally due to poor lubrication, the spring is stuck or damaged, oil or impurities stuck sliding part and other reasons. In this regard, we should first check the oil mist is working properly; the viscosity of the oil is suitable. If necessary, replace the lubricating oil, clean the sliding part of the valve, or replace the spring and the valve.
(2)換向閥經長時間使用后易泛起閥芯密封圈磨損、閥桿和閥座損傷的現象,導致閥內泄漏,閥的動作緩慢或不能正常換向等故障。對前3種情況應清洗先導閥及流動鐵芯上的油泥和雜質。
(3) if the solenoid pilot valve into the exhaust hole blocked by sludge and other debris, not tightly closed, the movable iron core clamping circuit failure, which can lead to the valve does not change. The pilot valve should be cleaned and the activity of sludge and impurities on the core of the former 3 cases. The circuit fault is generally divided into two types of control circuit fault and electromagnetic coil fault. Before checking the circuit fault, the valve should be turned on the manual knob several times, to see whether the nominal pressure of the valve can be normally reversed, if the normal commutation, the circuit is faulty. When the inspection, the instrument can be used to measure the voltage of the electromagnetic coil, to see whether the rated voltage, if the voltage is too low, it should be further check the power supply in the control circuit and the associated trip switch circuit. If the rated voltage of the valve can not be normal commutation, it should check the electromagnetic coil connector (plug) is loose or contact is not real. Method is to pull the plug, measure the coil resistance, if the resistance is too large or too small, indicating that the electromagnetic coil is damaged, should be replaced.。必要時,應更換潤滑油,清洗換向閥的滑動部門,或更換彈簧和換向閥。方法是,拔下插頭,丈量線圈的阻值,假如阻值太大或太小,說明電磁線圈已損壞,應更換。
