WH10、WH11、YK-3、YK-2、TS-1 series pressure switch(Europe and United States type)ng> | ng>一、概述 brief introductionng>
一般情況下，產生壓力的設備都有電動機驅的，如空壓機、水泵等，電動機的運轉、停止將直接操動著壓力的有無大小。如要使壓力保持在一定范圍，不可能用人力控制電機的工作，此時采用GYD系列氣壓自動控制開關，不但實現瞭操作自動化，而且節省人力、節約瞭能源，同時延長瞭機器使用壽命。
這類開關不僅適用於空氣壓力的自動控制，也可適用於水壓的控制。兩樣加瞭一些附件後也可作為鍋爐自動報警，卸壓和自動加水等。因此開關可廣泛用於氣壓自動控制場合。
In general,most equipment that can produce the pressure is driven by motor,like the air compressor,pump,etc.The run and stop of motor is directly related to toe pressure.If the pressure retains a certain range,it is impossible to control the service of motor by manual operation,in terms of this problem,we design GYD series air-pressure automatic control switch,this product not only realizes the automatic operation,but also saves the labor and energy source and is helpful for prolonging the service life of machine.
This switch is suitable for automatic control of air pressure or wated pressure,and also can be used for boliler alarm,pressure relief and automatic water feeding by means of equipping with the accessories.Therdfore,this switch widely serves the occasions that require the automatic control of air pressure. |
