全自動(dòng)攪拌車的自重壓力調(diào)節(jié)方法
全自動(dòng)攪拌車的自重壓力調(diào)節(jié)方法是怎樣的？您了解其中的相關(guān)內(nèi)容嗎？下面全自動(dòng)攪拌車廠家為您講解：
What is the self-weight pressure regulation method of the fully automatic mixer? Do you know the relevant content? The manufacturer of the automatic mixer will explain to you:
1.檢查液壓泵是否可以輸出液壓油。如果是沒有輸出液壓油的新型液壓泵，則泵體可能存在鑄造缺陷，因此吸入室和液壓室相連，油壓降低，并且制造商應(yīng)及時(shí)更換。如果不是新的液壓泵，并且沒有液壓油輸出，則可能無法正確操作泵，并且零件可能會嚴(yán)重磨損或損壞。
1. Check whether the hydraulic pump can output hydraulic oil. If it is a new hydraulic pump without output hydraulic oil, the pump body may have casting defects, so the suction chamber and hydraulic chamber are connected, the oil pressure is reduced, and the manufacturer should replace it in time. If it is not a new hydraulic pump and there is no hydraulic oil output, the pump may not be operated correctly and the parts may be seriously worn or damaged.
2.如果液壓泵有油輸出，請檢查閥是否正常工作。如果異常，則壓力油回路中的閥可能由于其他原因被污染或阻塞，并且處于回油位置，導(dǎo)致壓力油回路與溢流回路短路，或者管接頭可能松動(dòng)或受壓。油路中的某些閥泄漏嚴(yán)重，或者液壓缸和液壓馬達(dá)的密封件損壞，導(dǎo)致嚴(yán)重泄漏。
2. If the hydraulic pump has oil output, check whether the safety valve works normally. If it is abnormal, the valve in the pressure oil circuit may be contaminated or blocked for other reasons, and it is in the return position, resulting in a short circuit between the pressure oil circuit and the overflow circuit, or the pipe joint may be loose or under pressure. Some valves in the oil circuit leak seriously, or the seals of the hydraulic cylinder and hydraulic motor are damaged, resulting in serious leakage.
3.如果液壓泵的輸出流量隨壓力的增加而顯著下降，但壓力未達(dá)到規(guī)定值，則是由于液壓泵磨損后間隙的增加所致。
3. If the output flow of the hydraulic pump decreases significantly with the increase of pressure, but the pressure does not reach the specified value, it is due to the increase of clearance after the wear of the hydraulic pump.
如果全自動(dòng)攪拌車的整個(gè)液壓系統(tǒng)能夠建立正常壓力，并且某些管線或液壓缸（或液壓馬達(dá)）中沒有壓力，則可能是由于管線，小孔或節(jié)流閥，方向閥等引起的。進(jìn)行封鎖時(shí)，應(yīng)逐一檢查壓力和機(jī)油以找出原因并進(jìn)行清理。更多相關(guān)內(nèi)容就來咨詢我們http://www.zvmc.cn吧！
If the whole hydraulic system of the automatic mixer can establish normal pressure and there is no pressure in some pipelines or hydraulic cylinders (or hydraulic motors), it may be caused by pipelines, small holes or throttle valves, directional valves, etc. When blocking, check the pressure and oil one by one to find out the cause and clean it.
