如何自動(dòng)攪拌一體機(jī)液壓壓力表壓力不足的問題,以及如何混凝土攪拌機(jī)液壓系統(tǒng)的問題。當(dāng)自動(dòng)攪拌一體液壓系統(tǒng)的氣壓不足或根本沒有壓力時(shí),我們可以從以下幾個(gè)方面進(jìn)行調(diào)查。
How to solve the problem of insufficient pressure in the hydraulic pressure gauge of automatic mixing machine and how to solve the problem of hydraulic system of concrete mixer. When the air pressure of the automatic mixing integrated hydraulic system is insufficient or there is no pressure at all, we can investigate from the following aspects.
1. 檢查自動(dòng)攪拌一體液壓泵是否能輸出液壓油。如果是新液壓泵,沒有液壓油輸出,則可能是泵體有鑄造缺陷(縮孔、砂孔等),使吸油腔與油壓腔接觸,油壓能力損失,應(yīng)及時(shí)找廠家更換。如果沒有新的液壓泵,沒有液壓油輸出,則可能是泵轉(zhuǎn)向錯(cuò)誤,零件磨損或損壞,及時(shí)更換。
1. Check whether the automatic mixing hydraulic pump can output hydraulic oil. If it is a new hydraulic pump, and there is no hydraulic oil output, it may be that the pump body has casting defects (shrinkage cavity, sand hole, etc.), which makes the oil suction chamber contact with the oil pressure chamber, resulting in the loss of oil pressure capacity. It should be replaced by the manufacturer in time. If there is no new hydraulic pump and no hydraulic oil output, it may be the pump steering error, parts wear or damage, timely replacement.
2. 自動(dòng)攪拌一體液壓泵出油時(shí),檢查溢流閥是否工作正常。如果不正常,它可能是一個(gè)閥的壓力油線灰塵或其他原因,在回油位置,導(dǎo)致短路之間的壓力油線和溢出電路,也可以管接頭松動(dòng),或在壓力線一些油閥泄漏嚴(yán)重,或液壓缸,液壓馬達(dá)密封損壞,嚴(yán)重的泄漏。方法是打開閥門進(jìn)行清洗,檢查密封間隙大小及各種密封裝置,密封裝置損壞應(yīng)更換。
2. Check whether the relief valve works normally when the hydraulic pump of automatic mixing is discharging oil. If it is abnormal, it may be a valve pressure oil line dust or other reasons, in the oil return position, resulting in a short circuit between the pressure oil line and the overflow circuit, or loose pipe joints, or serious leakage of some oil valves in the pressure line, or the seal damage of hydraulic cylinder and hydraulic motor, serious leakage. The elimination method is to open the valve for cleaning, check the size of sealing clearance and various sealing devices, and replace the damaged sealing devices.
3.如果自動(dòng)攪拌一體液壓泵的輸出流量隨著壓力的增大而明顯減小,且壓力未達(dá)到規(guī)定值,則是由于液壓泵磨損后間隙增大引起的。方法是確定液壓泵的容積效率,可以確定泵是否可以繼續(xù)使用,對(duì)磨損嚴(yán)重的部件,應(yīng)進(jìn)行修理或更換。
3. If the output flow of the automatic mixing integrated hydraulic pump decreases obviously with the increase of pressure, and the pressure does not reach the specified value, it is caused by the increase of clearance after the hydraulic pump is worn. The elimination method is to determine the volumetric efficiency of the hydraulic pump, to determine whether the pump can continue to be used, and repair or replace the seriously worn parts.
4、自動(dòng)攪拌一體的液壓系統(tǒng)可建立正常壓力,而有些管路或液壓缸(或液壓馬達(dá))無(wú)壓力時(shí),則可能由于管路、開孔或節(jié)流閥、換向閥等部件堵塞。這時(shí)應(yīng)逐段檢查油壓和油液通過情況,找出原因,加以。
4. The hydraulic system of automatic mixing can establish normal pressure, but when some pipelines or hydraulic cylinders (or hydraulic motors) are not under pressure, they may be blocked by pipeline, opening or throttle valve, reversing valve and other parts. At this time, the oil pressure and oil passing through should be checked one by one to find out the causes and eliminate them.
以上是自動(dòng)攪拌一體為大家介紹的自動(dòng)攪拌一體壓力不足的處理方法。如攪拌車內(nèi)出現(xiàn)液壓系統(tǒng)壓力不足或根本沒有壓力時(shí),可按上述方法檢查,使混合器及時(shí)恢復(fù)正常狀態(tài)。
The above is the automatic mixing one for everyone to introduce the automatic mixing one pressure insufficient processing method. If the hydraulic system pressure in the mixer truck is insufficient or there is no pressure at all, it can be checked and solved according to the above methods, so that the mixer can be restored to normal state in time.
