如何提升混凝土攪拌機(jī)的液壓換向閥工作效能？當(dāng)然是維護(hù)保養(yǎng)了啊，維護(hù)保養(yǎng)的好，使用期就越長，工作效能就越高。

How to improve the working efficiency of the hydraulic reversing valve of the concrete mixer? Of course, it is maintenance. The better the maintenance, the longer the service life and the higher the work efficiency.

我們先講講攪拌機(jī)的液壓換向閥，這是操縱罐機(jī)正轉(zhuǎn)和翻轉(zhuǎn)的機(jī)械設(shè)備，是依據(jù)齒輪油流通的方位操縱方量的開始和關(guān)閉。再說說維護(hù)保養(yǎng)，須要立即拆換齒輪油，立即拆換齒輪油能夠降低對液壓換向閥的危害，從正轉(zhuǎn)改變翻轉(zhuǎn)或是從翻轉(zhuǎn)改變?yōu)檎D(zhuǎn)的那時(shí)候，減少罐機(jī)轉(zhuǎn)速比；定期維護(hù)混凝土攪拌機(jī)的液壓換向閥，立即查驗(yàn)液壓換向閥的問題，并且去處理它。

Let's first talk about the hydraulic reversing valve of the mixer, which is the mechanical equipment for controlling the forward rotation and overturning of the tank machine. It is used to control the start and closing of the volume according to the direction of the gear oil flow. Besides, for maintenance, it is necessary to immediately remove and replace the gear oil, which can reduce the harm to the hydraulic reversing valve. When the normal rotation is changed to the reverse rotation or the reverse rotation is changed to the normal rotation, the speed ratio of the tank machine can be reduced; Regularly maintain the hydraulic reversing valve of the concrete mixer, immediately check the problem of the hydraulic reversing valve and deal with it.

在液壓系、閥等元件中，相對運(yùn)動的元件之間都有精確的間隙，即很小的配合表面，有的液兒元件還有不少阻尼孔和縫隙式控制闖口等。如果液壓油中混人污物雜質(zhì)，在流經(jīng)這些部位時(shí)，則會堵塞這些小孔和縫隙，使元件不能正常工作。

In the hydraulic system, valves and other components, there is a precise gap between the relatively moving components, that is, a very small mating surface. Some liquid components also have many damping holes and slot control openings. If the hydraulic oil is mixed with dirt and impurities, when flowing through these parts, these holes and gaps will be blocked and the components will not work normally.

如果污物進(jìn)入閥芯與閥體等的配合間隙，則會劃傷配合表面，使泄漏增加，有時(shí)甚會卡住閥芯.造成元件動作失靈。如果油液中的污物過多，則會堵塞在油泵吸袖口設(shè)置的濾油網(wǎng)，從而造成吸油阻力過大，使油泵小能正常1:作，產(chǎn)生振動和噪聲。因此，應(yīng)該注意以下兒點(diǎn):

If dirt enters the fitting clearance between the valve core and the valve body, it will scratch the fitting surface, increase the leakage, and sometimes even jam the valve core Causing component action failure. If there is too much dirt in the oil, it will block the oil filter set at the suction sleeve of the oil pump, resulting in excessive oil suction resistance and normal operation of the oil pump, resulting in vibration and noise. Therefore, the following points should be noted:

①液壓用泊須經(jīng)過嚴(yán)格的過濾。濾油器應(yīng)當(dāng)經(jīng)常檢查清洗，如果發(fā)現(xiàn)損壞應(yīng)及時(shí)更換。向油箱中汗油時(shí)，應(yīng)通過1m目以上的濾油器過濾。

① Hydraulic berths must be strictly filtered. The oil filter shall be inspected and cleaned frequently. If it is found damaged, it shall be replaced in time. When the perspiration oil is added to the oil tank, it shall be filtered through an oil filter of 1m mesh or more.

②系統(tǒng)中的液壓應(yīng)經(jīng)常檢查并定期更換。一巴油液使用時(shí)間過長，將失去潤滑性能，并可能具右酸性，所以一般要求在累計(jì)工作1咖h以后換油o

② The hydraulic pressure in the system shall be inspected and replaced regularly. If one bar oil is used for too long, it will lose its lubricating performance and may have right acidity. Therefore, it is generally required to change the oil after accumulating 1 hour of operation

③液壓元件不要輕易拆卸。如須拆卸，則應(yīng)該在重新裝配時(shí)止金屬屑、棉紗等雜質(zhì)落人元件中。

③ Do not disassemble the hydraulic components easily. In case of disassembly, the impurities such as metal chips and cotton yarn shall be prevented from falling into the components during reassembly.

提升攪拌機(jī)的液壓換向閥工作效能靠保養(yǎng)的相關(guān)內(nèi)容就講解到這里了，如果您對此有什么疑惑可隨時(shí)來我們網(wǎng)站http://ffyhk.cn咨詢。
