冷再生機(jī)液壓系統(tǒng)故障怎么進(jìn)行排除
來源：http://www.kqj188.com/ 日期：2022-12-28 發(fā)布人：
由于就地冷再生技術(shù)具有良好的循環(huán)經(jīng)濟(jì)效益和環(huán)保效應(yīng)，因此越來越受到公路養(yǎng)護(hù)行業(yè)的重視，那么冷再生機(jī)液壓系統(tǒng)故障怎么進(jìn)行排除？下面冷再生機(jī)租賃廠家為您解答。
As the in situ cold regeneration technology has good circular economic benefits and environmental protection effects, it has been paid more and more attention by the road maintenance industry. How to remove the fault of the hydraulic system of the cold regeneration machine? The following cold regeneration machine rental manufacturer will answer for you.
從壓差閥閥芯受力分析看，該閥閥芯左側(cè)由彈簧彈力和來自梭閥的壓力油控制，右側(cè)由流出壓差閥的壓力油控制。在換向閥處于中位狀態(tài)下，閥芯左側(cè)只有彈簧彈力，右側(cè)有與系統(tǒng)壓力相當(dāng)?shù)挠蛪?，油壓作用力大于彈簧彈力，因此閥芯左移，主油道油口關(guān)閉,使壓差閥出油口免于進(jìn)油口壓力波動沖擊。
From the force analysis of the differential pressure valve core, the left side of the valve core is controlled by the spring force and the pressure oil from the shuttle valve, and the right side is controlled by the pressure oil flowing out of the differential pressure valve. When the reversing valve is in the neutral position, there is only spring force on the left side of the valve element, and there is oil pressure equivalent to the system pressure on the right side. The oil pressure force is greater than the spring force. Therefore, the valve element moves to the left, and the oil port of the main oil passage is closed, so that the oil outlet of the differential pressure valve is free from the impact of the pressure fluctuation at the oil inlet.
從壓差閥功能看，當(dāng)操縱換向閥時，系統(tǒng)壓力油經(jīng)過梭閥作用于壓差閥閥芯左側(cè)，使閥芯向右移動，油道口開度變大，流經(jīng)壓差閥的流量提升。由于換向閥對油流的節(jié)流作用，作用于壓差閥閥芯兩側(cè)的油壓產(chǎn)生壓差，換向閥開度越大，壓差越小。因此，換向閥開度越大，壓差閥開度越大，單位時間允許流過的壓力油越多，反之亦然。該閥可以起到流量補(bǔ)充、控制升降缸移動速度和保護(hù)系統(tǒng)免受沖擊的作用。
From the function of the differential pressure valve, when the directional valve is operated, the system pressure oil acts on the left side of the differential pressure valve spool through the shuttle valve, making the spool move to the right, the opening of the oil passage becomes larger, and the flow through the differential pressure valve increases. Due to the throttling effect of the reversing valve on the oil flow, the oil pressure acting on both sides of the differential pressure valve spool produces a pressure difference. The greater the opening of the reversing valve, the smaller the pressure difference. Therefore, the greater the opening of the directional valve, the greater the opening of the differential pressure valve, and the more pressure oil allowed to flow through the unit time, and vice versa. The valve can supplement the flow, control the moving speed of lifting cylinder and protect the system from impact.
