光源系統常見故障

Common faults of light source system

(a)燈光變暗。除光柵遮擋原因外，基本可以確定燈泡已接近使用壽命，可以更換新燈泡。氙氣燈泡的使用壽命一般設計為500小時。如果光源系統有一個壽命定時器裝置，這個問題就可以輕松。

(a) The lights dim. In addition to the grating blocking, it can be basically determined that the bulb is close to its service life and can be replaced with a new bulb. Xenon bulbs are generally designed for a service life of 500 hours. If the light source system has a life timer device, this problem can be easily solved.

(b)開機燈泡不亮。如果排除燒燈泡的原因，那么問題往往出在主機的高壓點火電路上，因為開機時，機器會產生幾萬伏的脈沖高壓，并且組件會很快老化。請注意，此時您不能使用萬用表檢查脈沖高壓。

(b) The power on bulb does not work. If the cause of bulb burning is eliminated, the problem often lies in the high-voltage ignition circuit of the host, because when the machine is turned on, it will generate tens of thousands of volts of pulse high voltage, and the components will age quickly. Please note that you cannot use a multimeter to check the pulse high voltage at this time.

人工氣腹系統常見故障

Common faults of artificial pneumoperitoneum system

(a)壓力顯示不正確。這主要是因為氣壓傳感器損壞。如果機器設計為一組多個同時工作的差壓傳感器，一般當其中一個老化或污染不能工作時，我們應該更換該組中的所有傳感器，否則只更換一個，并且其他的將被替換。同組的傳感器壽命也接近臨界。

(a) The pressure display is incorrect. This is mainly because the air pressure sensor is damaged. If the machine is designed as a group of multiple differential pressure sensors working at the same time, generally when one of them is aged or polluted and cannot work, we should replace all the sensors in the group, otherwise only one of them will be replaced, and the others will be replaced. The sensor life of the same group is also close to critical.

(b)流量不準確。如果氣體流量傳感器損壞，可以更換。有時流量是通過壓差來計算的，此時我們需要更換新的壓差傳感器。

(b) The flow is not accurate. If the gas flow sensor is damaged, it can be replaced. Sometimes the flow is calculated by the differential pressure. At this time, we need to replace the differential pressure sensor.

(c)設備泄漏。內窺鏡設備維修人員認為很多情況下是由于設備密封圈老化造成的。但也有設備機械減壓閥泄漏、電磁閥損壞等原因，比較容易判斷和維修。

(c) Equipment leakage. The maintenance personnel of endoscope equipment believe that in many cases, it is caused by the aging of equipment sealing ring. However, there are also mechanical pressure reducing valve leakage, solenoid valve damage and other reasons, which are relatively easy to judge and repair.

液體增壓系統常見故障

Common faults of liquid pressurization system

(a)蠕動泵損壞。

(a) The peristaltic pump is damaged.

(b)液壓傳感器損壞。原理與氣壓傳感器基本相同。

(b) The hydraulic sensor is damaged. The principle is basically the same as that of the air pressure sensor.

(c)設備內部電路損壞。

(c) The internal circuit of the equipment is damaged.

電凝切割系統常見故障

Common faults of electrocoagulation cutting system

(a)設備附件損壞。如腳踏開關、負極板線、連接線等常用易損配件。

(a) Equipment accessories are damaged. Such as foot switch, negative plate wire, connecting wire and other common vulnerable accessories.

(b)電切割、凝固、雙極故??障。在設備內部，這些部分都由不同的電路模塊組成。內窺鏡設備維修人員建議我們可以根據其故障現象維修或更換相應的模塊電路。

(b) Electric cutting, solidification, bipolar fault?? Obstacles. Inside the equipment, these parts are composed of different circuit modules. The maintenance personnel of endoscope equipment suggest that we can repair or replace the corresponding module circuit according to its fault phenomenon.
