液壓系統(tǒng)安裝和調(diào)試
Installation and commissioning of hydraulic system
1. 安裝
1. Installation
液壓站在安裝前應(yīng)首先作地基平整處理，并打好地腳螺絲的預(yù)埋坑。
Prior to installation of the hydraulic station, firstly level the foundation, and dig the embedded pits for the foundation bolts.
2．調(diào)試
2. Commissioning
1）首先加入液壓工作油,一般地區(qū),采用YB-46抗磨液壓油,在高溫地區(qū),應(yīng)加入YB-N80抗磨液壓油.在溫差較大的地區(qū),則選擇粘溫系數(shù)良好的航空液壓油10號(hào)或12號(hào)。
1) Fill the hydraulic operating oil, in ordinary regions, adopt YB-46 anti-wear hydraulic oil; and in high temperature regions, apply YB-N80 anti-wear hydraulic oil. In those regions with a high temperature difference, adopt the aviation hydraulic oil #10 or #12 which has a good viscosity-temperature coefficient.
2）檢查液壓系統(tǒng)各部，確認(rèn)安裝合理無誤。gxgkickz.com
2) Inspect all parts of the hydraulic system to confirm the installation is proper and errorless.
3）向油箱灌油，當(dāng)油液充滿液壓泵后，用手轉(zhuǎn)動(dòng)聯(lián)軸節(jié)，直至泵的出油口出油并不見氣泡時(shí)為止。有泄油口的泵，要向泵殼體中灌滿油。
3) Fill oil into the oil tank, when the hydraulic pump is full of oil fluid, manually turn the coupling, till there is no bubble in the oil outlet. If the pump is fitted with oil drain port, firstly fill oil in the pump case.
4）接通電源、點(diǎn)動(dòng)液壓泵電機(jī)，檢查電源連線是否正確。延長啟動(dòng)時(shí)間，檢查空運(yùn)轉(zhuǎn)有無異常。
4) Switch on the power supply, start up the motor for hydraulic pump in the inching mode, and inspect if the power wire is connected correctly. Extend the startup time to check if there is abnormal condition under zero load.
5）主油缸排氣：當(dāng)機(jī)床長時(shí)間不使用，主油缸內(nèi)液壓油泄回油池，使系統(tǒng)內(nèi)積聚空氣使機(jī)床產(chǎn)生爬行，若重新啟用，可將放氣開關(guān)打開（如圖所示），主油缸上下兩腔的空氣通過放氣開關(guān)，排出系統(tǒng)。經(jīng)過幾個(gè)循環(huán)后，徹底排盡。注意：在進(jìn)入拉削時(shí)一定要關(guān)閉放氣開關(guān)。
5) Exhausting of main oil cylinder: if the machine tool is not in service for a long term, drain the hydraulic oil in the main cylinder into the oil basin, so as to make the accumulated air in the system force the machine tool to creep; when the machine is put into service again, open the air escape cock (as shown in the following figure), the air in both upper and lower chambers of the cylinder will be discharged out of the system through the air escape cock. After several cycles, the air will be emptied. Notice: When broaching, make sure that the air escape cock is closed.
6）液壓系統(tǒng)生產(chǎn)運(yùn)行過程中，要注意油質(zhì)的變化狀況，要定期取樣化驗(yàn)，若發(fā)現(xiàn)油質(zhì)不符合要求，要進(jìn)行凈化處理或更換新油液。
6) During the running of the hydraulic system, pay attention to the condition of oil quality, periodically take a sample to test, in case any defective oil is found, take a cleaning treatment or replace with new oil.
