裝料，卸料，攪拌罐的轉(zhuǎn)動等都離不開液壓系統(tǒng)，所以液壓系統(tǒng)對于自動攪拌車是非常重要的，很多攪拌車的車主都會遇到這樣的問題，那就是液壓系統(tǒng)的壓力不足，這讓車主們很是著急，那這到底是為什么呢？

Loading, unloading, and the rotation of the mixing tank are all inseparable from the hydraulic system, so the hydraulic system is very important for automatic mixer trucks. Many mixer truck owners will encounter this problem, that is, the pressure of the hydraulic system is insufficient, which makes the owners very worried. Why on earth is this?

1.查看自動上料攪拌車的液壓泵是否能夠輸出液壓油。對于新的液壓泵，液壓油或許不會流出，并且泵體中或許會呈現(xiàn)鑄件缺陷（收縮，沙孔等）。由于吸入室和液壓室已銜接，液壓容量將耗盡，請盡快替換泵體。假如不是新的液壓泵且沒有液壓輸出，則泵轉(zhuǎn)向或許不正確，零件嚴(yán)峻磨損或損壞，應(yīng)及時替換

1. Check whether the hydraulic pump of the automatic feeding mixer can output hydraulic oil. For new hydraulic pumps, the hydraulic oil may not flow out, and casting defects (shrinkage, sand holes, etc.) may appear in the pump body. As the suction chamber and hydraulic chamber are connected, the hydraulic capacity will be exhausted. Please replace the pump body as soon as possible. If it is not a new hydraulic pump and there is no hydraulic output, the pump steering may be incorrect, and the parts are severely worn or damaged, so they should be replaced in time

2.假如自動上料攪拌車的液壓泵中有油，請查看溢流閥是否正常作業(yè)。假如產(chǎn)生異常，壓力油回路的閥或許由于塵埃和其他原因而被卡住，并且有可能處于回油位置，然后導(dǎo)致壓力油回路與溢流管線之間產(chǎn)生短路。

2. If there is oil in the hydraulic pump of the automatic feeding mixer, please check whether the overflow valve operates normally. In case of any abnormality, the valve of the pressure oil circuit may be stuck due to dust and other reasons, and may be in the oil return position, which may cause a short circuit between the pressure oil circuit and the overflow pipeline.

接頭松動或液壓回路中有接頭。一些閥嚴(yán)峻走漏，或許液壓缸和液壓馬達(dá)上的密封件損壞，導(dǎo)致嚴(yán)峻走漏。要卸下它，請拆卸并清洗適用的閥門，查看密封空隙和各種密封設(shè)備的尺寸，假如密封設(shè)備損壞，請?zhí)鎿Q密封設(shè)備。

Loose connectors or connectors in the hydraulic circuit. Some valves leak severely. Perhaps the seals on the hydraulic cylinder and hydraulic motor are damaged, resulting in severe leakage. To remove it, disassemble and clean the applicable valve, check the sealing clearance and dimensions of various sealing devices, and replace the sealing device if it is damaged.

3.假如跟著壓力的添加，移動式自動進(jìn)料混合器的液壓泵的輸出流量明顯下降，并且壓力未達(dá)到指定值，這是由于液壓泵磨損后的空隙添加所造成的。拆卸方法是丈量液壓泵的容積功率，以確定泵是否仍然可用。嚴(yán)峻磨損的零件應(yīng)修補(bǔ)或替換。

3. If the output flow of the hydraulic pump of the mobile automatic feed mixer decreases significantly with the addition of pressure, and the pressure does not reach the specified value, this is due to the gap addition after the wear of the hydraulic pump. The removal method is to measure the volume power of the hydraulic pump to determine whether the pump is still available. Parts severely worn shall be repaired or replaced.

4.自動上料攪拌車的液壓體系能夠樹立常壓，某些管道或液壓缸（或液壓馬達(dá)）沒有壓力。這或許是由于管道，小孔或節(jié)流閥，方向控制閥和其他組件的阻塞引起的。此刻，必須逐漸查看油壓和油的存在，以找出原因并消除。

4. The hydraulic system of the automatic feeding mixer can establish normal pressure, and some pipes or hydraulic cylinders (or hydraulic motors) have no pressure. This may be caused by blockage of pipes, orifices or throttles, directional control valves and other components. At this moment, the existence of oil pressure and oil must be checked gradually to find out the cause and eliminate it.
