全自動攪拌車的正常工作都是靠液壓系統(tǒng)的帶動來完成的，而液壓泵和液壓馬達(dá)也是液壓系統(tǒng)中非常關(guān)鍵的部件，特別是液壓泵，下面小編就為大家介紹一下它的液壓泵的使用注意事項。

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.

在使用前一定要確認(rèn)液壓泵是否安裝到位，螺釘是否擰緊，聯(lián)軸器安裝是否符合要求。然后檢查泵體內(nèi)是否加滿符合標(biāo)號的液壓油。再次檢查泵的轉(zhuǎn)向是否與進(jìn)出油口相符，液壓系統(tǒng)的閥是否調(diào)到規(guī)定壓力值。

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.

在使用全自動攪拌車液壓泵時切不可急劇全速啟動，應(yīng)在系統(tǒng)卸荷狀態(tài)下點動原動機(jī)開關(guān)數(shù)次后才能連續(xù)空載運轉(zhuǎn)，目的是將管道中的空氣盡可能排除干凈，空載運轉(zhuǎn)1~2min無異常現(xiàn)象后逐漸加載，加載過程中應(yīng)無異常振動、噪聲和泄漏，否則立即停機(jī)檢查分析、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.

在長時間的使用后一定要注意更換液壓油，這樣才能保證油泵處于好的工作狀態(tài)。

Pay attention to changing the hydraulic oil after long-term use, so as to ensure that the oil pump is in good working condition.

全自動攪拌車液壓泵使用注意事項：

Precautions for use of hydraulic pump of automatic mixer truck:

①液壓泵啟動時應(yīng)先點動數(shù)次，油流方向和聲音都正常后，在低壓下運轉(zhuǎn)5～10min，然后投入正常運行。柱塞泵啟動前，需要通過殼上的泄油口向泵內(nèi)灌滿清潔的工作油。

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油的黏度受溫度影響而變化，油溫升高黏度隨之降低，故油溫要求保持在60℃以下，為使液壓泵在不同的工作溫度下能夠穩(wěn)定工作，所選的油液應(yīng)具有黏度受溫度變化影響較小的油溫特性，以及較好的化學(xué)穩(wěn)定性、抗泡沫性能等。使用L-HM32或L-HM46（GB11118.1—94）抗磨液壓油。

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油液需要潔凈、不得混有機(jī)械雜質(zhì)和腐蝕物質(zhì)，吸油管路上無過濾裝置的液壓系統(tǒng)，需要經(jīng)濾油車（過濾精度小于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液壓泵的高壓力和高轉(zhuǎn)速，是指在使用中短暫時間內(nèi)允許的峰值，應(yīng)避免長期使用，否則將影響液壓泵的壽命。

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液壓泵的正常工作油溫為15～65℃，泵殼上的高溫度一般比油箱內(nèi)泵入口處的油溫高10～20℃，當(dāng)油箱內(nèi)油溫達(dá)65℃時，泵殼上高溫度不超過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 ℃.
