1、如果說水泥自上料攪拌車液壓泵有油液輸出的情況發生,我們可以及時查看它的工作是不是正常。如果不正常,有可能是壓力油路中的某個設備配件其他原因被卡住,處于回油的地方,導致壓力油路和溢流回路短路的情況發生,也或許是管接頭有松動的情況發生,當我們處在油路中的某些設備漏油嚴重,或液壓缸、液壓馬達的密封被損壞。排除的辦法就是直接拆開有關設備來清洗,看看對應的設備是不是損壞了,該更換就換,該檢查就查看一下。
1. If there is oil output from the hydraulic pump of cement loading mixer truck, we can check whether it works normally in time. If it is not normal, it may be that one of the equipment accessories in the pressure oil circuit is stuck for other reasons and is in the place of oil return, resulting in the short circuit of the pressure oil circuit and overflow circuit. It may also be that the pipe joint is loose. When some equipment in the oil circuit leaks seriously, or the seals of the hydraulic cylinder and hydraulic motor are damaged. The way to eliminate this problem is to directly disassemble the relevant equipment for cleaning to see if the corresponding equipment is damaged. Replace it when necessary and check it when necessary.
2、看水泥自上料攪拌車液壓泵是不是能輸出液壓油呢。如果說是新的液壓泵,沒有液壓油,可能是泵體有缺陷,讓吸油腔和壓油腔有相通的情況發生,失去壓油能力,應及時找海田重工更換。若不是新的液壓泵,無液壓油輸出,則可能是泵的轉向不對,零件磨損嚴重或損壞,及時更換。
2. See if the hydraulic pump of cement self loading mixer can output hydraulic oil. If it is a new hydraulic pump without hydraulic oil, it may be that the pump body is defective, so that the oil suction chamber and oil pressure chamber are connected. If the oil pressure capacity is lost, it should be replaced by Haitian heavy industry in time. If it is not a new hydraulic pump and there is no hydraulic oil output, the steering of the pump may be wrong, and the parts may be seriously worn or damaged. Replace them in time.
3、水泥自上料攪拌車的液壓系統能建立正常壓力,一些管路或者液壓缸中間是沒有壓力的,可能就是因為管路、小孔或節流閥、換向閥這些部位堵住了。所以要仔細查看檢查壓力有沒有油液通過,找出原因,然后來排除。
3. The hydraulic system of the cement self loading mixer can establish normal pressure. There is no pressure in some pipelines or hydraulic cylinders. It may be because the pipelines, small holes, throttle valves and directional valves are blocked. Therefore, check carefully to see if there is oil passing through the pressure, find out the cause, and then eliminate it.
4、若水泥自上料攪拌車的液壓泵輸出流量隨壓力升高而顯著減小,且壓力達不到規定值,則是由于液壓泵磨損后間隙過大所致。排除方法是測定液壓泵的容積效率,就可以確定這個泵是不是能繼續使用的,對磨損嚴重的產品,一定進行修配或更換。
4. If the output flow of the hydraulic pump from the cement loading mixer decreases significantly with the increase of pressure, and the pressure cannot reach the specified value, it is due to the excessive clearance after the hydraulic pump is worn. The elimination method is to measure the volumetric efficiency of the hydraulic pump, so as to determine whether the pump can continue to be used. The severely worn products must be repaired or replaced.
