水泥自動攪拌車夜間行車操作應該注意什么?

在自動攪拌一體車運用過程中,假定液壓體系呈現缺點會使攪拌車的作業功用大大下降,只需了解了液壓體系的缺點原因并及時排出處理缺點才華使攪拌車康復正常,今日收集了有關攪拌車液壓體系壓力短少或完全無壓力的原因、確診和清掃,希望能幫到咱們。
In the application process of the automatic mixer, if the hydraulic system presents defects, the operation function of the mixer will be greatly reduced. Only by understanding the causes of the defects of the hydraulic system and timely handling the defects can the mixer recover normally. Today, we collected the causes, diagnosis and cleaning of the short or no pressure of the hydraulic system of the mixer, hoping to help us.
假定自動攪拌一體車呈現液壓體系壓力短少或完全無壓力時,咱們能夠依據以下幾個方面順次進行排查:
Assuming that the hydraulic system pressure of the automatic mixer is short or no pressure at all, we can check in sequence according to the following aspects:
查看液壓泵是否能輸出液壓油。假定是新的液壓泵,無液壓油輸出,可能是泵體有鑄造缺點(縮孔、砂眼等),使吸油腔和壓油腔相通,失掉壓油才華,應及時找廠家替換。若不是新的液壓泵,無液壓油輸出,則可能是泵的轉向不對,零件磨損嚴峻或損壞,及時替換。
Check whether the hydraulic pump can output hydraulic oil. If it is a new hydraulic pump without hydraulic oil output, the pump body may have casting defects (shrinkage cavity, sand hole, etc.), so that the oil suction cavity is connected with the oil pressure cavity, and the oil pressure talent is lost, it should be replaced by the manufacturer in time. If it is not a new hydraulic pump and there is no hydraulic oil output, it may be that the steering of the pump is not correct, the parts are severely worn or damaged, and they shall be replaced in time.
若液壓泵有油液輸出,查看溢流閥作業是否正常。若不正常,則可能是壓力油路的某幾個閥有污物或其他原因卡住,處于回油方位,致使壓力油路與溢流回路短路,也可能是管接頭松脫,或處于壓力油路中的某些閥走漏嚴峻,或液壓缸、液壓馬達的密封損壞,嚴峻走漏。

If the hydraulic pump has oil output, check whether the overflow valve operates normally. If it is abnormal, it may be that some valves of the pressure oil circuit are stuck due to dirt or other reasons, which are in the oil return direction, resulting in a short circuit between the pressure oil circuit and the overflow circuit, or the pipe joint is loose, or some valves in the pressure oil circuit leak severely, or the seal of the hydraulic cylinder and hydraulic Marta is damaged, which leads to severe leakage.
清掃辦法:拆開有關閥進行清洗,查看密封空位的巨細及各種密封設備,密封設備損壞應替換。
Cleaning method: disassemble relevant valves for cleaning, check the size of sealing space and various sealing equipment, and replace the damaged sealing equipment.
若液壓泵輸出流量隨壓力升高而明顯減小,且壓力達不到規定值,則是因為液壓泵磨損后空位增大所構成的。
If the output flow of the hydraulic pump decreases obviously with the increase of the pressure, and the pressure can not reach the specified value, it is caused by the increase of the vacancy after the wear of the hydraulic pump.
清掃辦法:測定液壓泵的容積功率,即可供認該泵是否能持續運用,對磨損嚴峻的零件,應進行修配或替換。
Cleaning method: measure the volume power of the hydraulic pump to confirm whether the pump can be used continuously. Repair or replace the severely worn parts.
若整個自動攪拌一體車液壓體系能樹立正常壓力,而某些管路或液壓缸(或液壓馬達)中沒有壓力,就有可能是因為小孔、管路或許換向閥、節流閥等部位阻塞。此刻,應逐段查看壓力和有無油液經過,找出原因,加以清掃。
If the hydraulic system of the whole automatic mixer can set up normal pressure, and there is no pressure in some pipelines or hydraulic cylinders (or hydraulic motors), it may be because of the blockage of small holes, pipelines or reversing valves, throttle valves and other parts. At this moment, it is necessary to check the pressure and oil flow section by section, find out the cause and clean it.
