全自动搅拌车的正常工作都是靠液压系统的带动来完成的，而液压泵和液压马达也是液压系统中非常关键的部件，特别是液压泵，下面小编就为大家介绍一下它的液压泵的使用注意事项。
The normal operation of the full-automatic mixer truck is completed by the drive of the hydraulic system, and the hydraulic pump and hydraulic motor are also very key components of the hydraulic system, especially the hydraulic pump. The following small series will introduce the precautions for the use of its hydraulic pump.
在使用前一定要确认液压泵是否安装到位，螺钉是否拧紧，联轴器安装是否符合要求。然后检查泵体内是否加满符合标号的液压油。再次检查泵的转向是否与进出油口相符，液压系统的阀是否调到规定压力值。
Before use, make sure whether the hydraulic pump is installed in place, whether the screws are tightened, and whether the coupling installation meets the requirements. Then check whether the pump body is filled with hydraulic oil conforming to the label. Check again whether the steering of the pump is consistent with the oil inlet and outlet, and whether the safety valve of the hydraulic system is adjusted to the specified pressure value.
在使用全自动搅拌车液压泵时切不可急剧全速启动，应在系统卸荷状态下点动原动机开关数次后才能连续空载运转，目的是将管道中的空气尽可能排除干净，空载运转1~2min无异常现象后逐渐加载，加载过程中应无异常振动、噪声和泄漏，否则立即停机检查分析、排除故障。
When using the hydraulic pump of the full-automatic mixer truck, it is not allowed to start at full speed. The continuous no-load operation can be carried out only after the prime mover switch is jogged several times under the unloading state of the system. The purpose is to eliminate the air in the pipeline as much as possible. After no-load operation for 1-2min, there shall be no abnormal phenomenon, and then gradually load. During the loading process, there shall be no abnormal vibration, noise and leakage. Otherwise, stop the machine immediately for inspection and analysis and troubleshooting.
在长时间的使用后一定要注意更换液压油，这样才能保证油泵处于好的工作状态。
Pay attention to changing the hydraulic oil after long-term use, so as to ensure that the oil pump is in good working condition.
全自动搅拌车液压泵使用注意事项：
Precautions for use of hydraulic pump of automatic mixer truck:
①液压泵启动时应先点动数次，油流方向和声音都正常后，在低压下运转5～10min，然后投入正常运行。柱塞泵启动前，需要通过壳上的泄油口向泵内灌满清洁的工作油。
① When the hydraulic pump is started, it shall be inched for several times. After the oil flow direction and sound are normal, it shall be operated under low pressure for 5-10min and then put into normal operation. Before starting the plunger pump, it is necessary to fill the pump with clean working oil through the oil drain port on the casing.
②油的黏度受温度影响而变化，油温升高黏度随之降低，故油温要求保持在60℃以下，为使液压泵在不同的工作温度下能够稳定工作，所选的油液应具有黏度受温度变化影响较小的油温特性，以及较好的化学稳定性、抗泡沫性能等。使用L-HM32或L-HM46（GB11118.1—94）抗磨液压油。
② The viscosity of oil changes with the influence of temperature, and the viscosity decreases with the increase of oil temperature. Therefore, the oil temperature is required to be kept below 60 ℃. In order to enable the hydraulic pump to work stably under different operating temperatures, the selected oil shall have the oil temperature characteristics with little influence of temperature change, as well as better chemical stability and anti foam performance. L-hm32 or l-hm46 (gb11118.1-94) anti-wear hydraulic oil is recommended.
③油液需要洁净、不得混有机械杂质和腐蚀物质，吸油管路上无过滤装置的液压系统，需要经滤油车（过滤精度小于25μm）加油油箱。
③ The oil shall be clean and shall not be mixed with mechanical impurities and corrosive substances. The hydraulic system without filter device on the oil suction pipeline shall be filtered by the oil filter truck (the filtering accuracy is less than 25 μ m) Add oil to the oil tank.
④液压泵的高压力和高转速，是指在使用中短暂时间内允许的峰值，应避免长期使用，否则将影响液压泵的寿命。
④ The high pressure and high rotation speed of the hydraulic pump refer to the allowable peak value in a short time during use. Long term use shall be avoided, otherwise the service life of the hydraulic pump will be affected.
⑤液压泵的正常工作油温为15～65℃，泵壳上的高温度一般比油箱内泵入口处的油温高10～20℃，当油箱内油温达65℃时，泵壳上高温度不超过75～85℃。
⑤ The normal working oil temperature of the hydraulic pump is 15 ~ 65 ℃, and the high temperature on the pump shell is generally 10 ~ 20 ℃ higher than the oil temperature at the pump inlet in the oil tank. When the oil temperature in the oil tank reaches 65 ℃, the high temperature on the pump shell does not exceed 75 ~ 85 ℃.
以上就是全自动搅拌车液压泵使用注意事项，希望大家学会以后以正确的使用液压泵，以免产生不必要的后果。更多相关注意实现就来我们网站http://www.zkzdsljbc.com咨询了解吧。
