光源系統(tǒng)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(shè)計(jì)為500小時(shí)。如果光源系統(tǒng)有一個(gè)壽命定時(shí)器裝置，這個(gè)問(wèn)題就可以輕松解決。

(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(jī)燈泡不亮。如果排除燒燈泡的原因，那么問(wèn)題往往出在主機(jī)的高壓點(diǎn)火電路上，因?yàn)殚_機(jī)時(shí)，機(jī)器會(huì)產(chǎn)生幾萬(wàn)伏的脈沖高壓，并且組件會(huì)很快老化。請(qǐng)注意，此時(shí)您不能使用萬(wàn)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(tǒng)常見故障

Common faults of artificial pneumoperitoneum system

(a)壓力顯示不正確。這主要是因?yàn)闅鈮簜鞲衅鲹p壞。如果機(jī)器設(shè)計(jì)為一組多個(gè)同時(shí)工作的差壓傳感器，一般當(dāng)其中一個(gè)老化或污染不能工作時(shí)，我們應(yīng)該更換該組中的所有傳感器，否則只更換一個(gè)，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(zhǔn)確。如果氣體流量傳感器損壞，可以更換。有時(shí)流量是通過(guò)壓差來(lái)計(jì)算的，此時(shí)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(shè)備泄漏。內(nèi)窺鏡設(shè)備維修人員認(rèn)為很多情況下是由于設(shè)備密封圈老化造成的。但也有設(shè)備機(jī)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(tǒng)常見故障

Common faults of liquid pressurization system

(a)蠕動(dòng)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(shè)備內(nèi)部電路損壞。

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

電凝切割系統(tǒng)常見故障

Common faults of electrocoagulation cutting system

(a)設(shè)備附件損壞。如腳踏開關(guān)、負(fù)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(shè)備內(nèi)部，這些部分都由不同的電路模塊組成。內(nèi)窺鏡設(shè)備維修人員建議我們可以根據(jù)其故障現(xiàn)象維修或更換相應(yīng)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.
