隨著科技的發(fā)展，變頻控制在液壓貨梯http://m.qiangwuditan.com/中得到越來(lái)越廣泛的應(yīng)用。變頻調(diào)速具有啟停過(guò)程平穩(wěn)、減少機(jī)械沖擊、增加乘員的舒適性、提高使用壽命等特點(diǎn)，同時(shí)也可通過(guò)改變供電頻率調(diào)節(jié)速度，節(jié)約電能，提高工作效率，但是變頻調(diào)速系統(tǒng)在使用過(guò)程中會(huì)存在干擾，往往會(huì)造成液壓貨梯安全事故的發(fā)生。
With the development of science and technology, frequency control to be more widely used in the hydraulic freight elevators. Frequency has a smooth start and stop the process, reduce the mechanical impact and increase occupant comfort,improve service life, but also can adjust the speed by changing the frequency of the power supply, save energy, improve efficiency, but the frequency control system in use will be the presence of interference, often causing the hydraulic freight elevator accidents happen.

液壓貨梯http://m.qiangwuditan.com/的變頻調(diào)速系統(tǒng)受干擾后，會(huì)使系統(tǒng)程序運(yùn)行失控，導(dǎo)致電機(jī)運(yùn)行時(shí)快時(shí)慢，吊籠上下運(yùn)行的速度不穩(wěn)定；使控制失靈，出現(xiàn)停止按鈕和急停按鈕不起作用，電機(jī)停不下來(lái)等現(xiàn)象，可能引起液壓升降機(jī)失控或高空墜落，造成安全事故。
The frequency control system of hydraulic freight elevator after interference can cause your system is running out of control, causing the motor is running faster or slower, running up and down the cage instability speed; so out of control, the Stop button and the emergency stop button does not work, the motor can not stop such phenomena may cause loss of control or by falling hydraulic lift, causing accidents.
