自上料攪拌車壓力不足的方法
查看自上料攪拌車液壓泵是否能輸出液壓油。如果是新的液壓泵，無液壓油輸出，可能是泵體有鑄造缺陷（縮孔、砂眼等），使吸油腔和壓油腔相通，失去壓油能力，應(yīng)及時(shí)找廠家更換。若不是新的液壓泵，無液壓油輸出，可能是泵的轉(zhuǎn)向不對(duì)，零件磨損嚴(yán)重或損壞，及時(shí)更換。
Check whether the hydraulic pump of the self loading mixer truck can output hydraulic oil. If it is a new hydraulic pump without hydraulic oil output, it may be that the pump body has casting defects (shrinkage cavity, sand hole, etc.), which connects the oil suction chamber and oil pressure chamber and loses the oil pressure capacity. 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 wrong, and the parts are seriously worn or damaged. Replace them in time.
若自上料攪拌車液壓泵有油液輸出，查看溢流閥工作是否正常。若不正常，則可能是壓力油路中的某個(gè)閥有污物或其他原因卡住，處于回油位置，致使壓力油路與溢流回路短路。
If there is oil output from the hydraulic pump of the loading mixer truck, check whether the overflow valve works normally. If it is abnormal, it may be that a valve in the pressure oil circuit is stuck due to dirt or other reasons and is in the oil return position, resulting in a short circuit between the pressure oil circuit and the overflow circuit.
也可能是管接頭松脫，或處于壓力油路中的某些閥泄漏嚴(yán)重，或液壓缸、液壓馬達(dá)的密封損壞，嚴(yán)重泄漏。排除方法是拆開有關(guān)閥進(jìn)行清洗，檢查密封間隙的大小及各種密封裝置，密封裝置損壞應(yīng)更換。
It may also be that the pipe joint is loose, or some valves in the pressure oil circuit leak seriously, or the seals of the hydraulic cylinder and hydraulic motor are damaged and leak seriously. The troubleshooting method is to disassemble the relevant valves for cleaning, check the size of the sealing gap and various sealing devices, and replace the damaged sealing devices.
若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(dá)不到規(guī)定值，則是由于液壓泵磨損后間隙變大所致。排除方法是測(cè)定液壓泵的容積效率，即可確定該泵是否能繼續(xù)使用，對(duì)磨損嚴(yán)重的零件，應(yīng)進(jìn)行修配或更換。
If the output flow of the hydraulic pump from the loading mixer decreases significantly with the increase of pressure, and the pressure cannot reach the specified value, it is due to the larger clearance after the hydraulic pump is worn. The elimination method is to measure the volumetric efficiency of the hydraulic pump to determine whether the pump can continue to be used. The parts with serious wear should be repaired or replaced.
此外自上料攪拌車廠家認(rèn)為攪拌車一般在施工現(xiàn)場(chǎng)，工作人員的工作質(zhì)量也會(huì)影響系統(tǒng)的使用。在設(shè)備的維護(hù)和清洗中，傳感器很可能會(huì)被高壓水濺到，誤操作可能導(dǎo)致過載。為了使傳感器能夠在這樣的環(huán)境條件下長(zhǎng)期可靠地工作，需要進(jìn)行一些特殊的設(shè)計(jì)。
In addition, since the mixer truck manufacturer believes that the mixer truck is generally on the construction site, the work quality of the staff will also affect the use of the system. During the maintenance and cleaning of the equipment, the sensor is likely to be splashed by high-pressure water, and misoperation may lead to overload. In order to make the sensor work reliably under such environmental conditions for a long time, some special designs are needed.
