旋挖鉆機液壓系統(tǒng)、電器維護(hù)概要/Overview of Maintenance

液壓系統(tǒng)/Hydraulic system

●工作中和工作后，液壓系統(tǒng)處在高溫下。操作時，它還處在高壓狀態(tài)，因此當(dāng)時液壓系統(tǒng)進(jìn)行檢查和保養(yǎng)時，要特別注意先等溫度降下來并釋放掉液壓油缸管路中的壓力。

During and after operation, the hydraulic system is in high temperature. During operation, it is still in high pressure state, so when checking and maintaining the hydraulic system, pay special attention to wait for the temperature to drop and release the pressure in the hydraulic cylinder pipeline.

●當(dāng)松開螺塞、螺絲或軟管接頭時，不要站在零件前面，在拆卸前，要逐漸地松開以釋放壓內(nèi)部壓力。

When loosening the screw plug, screw or hose connector, do not stand in front of the part. Before disassembling, gradually loosen to release the internal pressure.

●當(dāng)對液壓油路進(jìn)行檢查或保養(yǎng)時，一定要排出空氣以釋放出內(nèi)部壓力。

 When inspecting or maintaining the hydraulic oil lines, be sure to discharge air to release internal pressure.

●液壓系統(tǒng)的檢查或保養(yǎng)內(nèi)賽包括:檢查液壓油油位、更換濾芯和添加液壓油。

The inspection or maintenance of the hydraulic system includes: check the hydraulic oil level, replace the filter element and add the hydraulic oil.

●當(dāng)拆卸高壓軟管時，檢查O形圈是否損壞。如果損壞，進(jìn)行更換。

When removing the high-pressure hose, check the O-ring for damage. If it is damaged, then replace.

●當(dāng)在有O型圈或密封墊密封的部位拆卸零件時，要清潔安裝表面并用新零件更換。

When disassembling parts with o-rings or gasket seals, clean the mounting surface and replace with new ones.

●當(dāng)安裝軟管時，不允許扭曲軟管或彎曲成小直徑的圈。這樣會損壞軟管并明顯縮短軟管的使用壽命。

When installing the hose, do not twist the hose or bend it into a small diameter ring.This can damage the hose and significantly shorten the life of the hose.

電氣系統(tǒng)/Electrical system

●電氣設(shè)備受潮或電線的絕緣層損壞是非常危險的。這樣會造成器電并導(dǎo)致機器故障，不要用水沖洗駕駛室內(nèi)部。但沖洗機器時，注意不要讓水進(jìn)入電氣部件。

It is very dangerous for electrical equipment to get damp or the insulation of wires to be damaged. This will cause power and machine failure. Do not flush the inside of the cab with water. But when washing the machine, be careful not to let water enter the electrical components.

●有關(guān)電氣系統(tǒng)的維護(hù):檢查并維護(hù)蓄電池液位;更換各種燈泡;更換保險絲和繼電器等。

Maintenance related to electrical system: check and maintain battery level; replace various bulbs; replace fuses and relays.

●在海灘工作時，要認(rèn)真清潔電氣系統(tǒng)以防止腐蝕。

When working at the beach, carefully clean the electrical system to prevent corrosion.

●當(dāng)安裝駕駛室冷風(fēng)機或其它電氣設(shè)備時，應(yīng)將它接到專門的電源接頭上，選用的電源不能連接到保險絲、起動開關(guān)或蓄電池繼電器上。

When installing the air cooler or other electrical equipment of driver cab, it should be connected to a special power connector. The selected power source cannot be connected to the fuse, starter switch or battery relay.
