In road construction, especially in high-grade highway construction, loaders are used for filling and excavation of subgrade engineering, aggregate and loading of asphalt mixture and cement concrete stockyard. In addition, it can also push and transport soil, scrape the ground and pull other machinery. Because the loader has the advantages of fast operation speed, high efficiency, good mobility and light operation, it has become one of the main types of earthwork construction in engineering construction.

一、裝載機轉(zhuǎn)向系統(tǒng)有哪些特點？

1、 What are the characteristics of loader steering system?

目前我們的裝載機液壓轉(zhuǎn)向系統(tǒng)采用開式定量泵系統(tǒng)，其特點是結(jié)構(gòu)簡單、散熱充分。轉(zhuǎn)向液壓系統(tǒng)又有合流系統(tǒng)與不合流系統(tǒng)之分。合流系統(tǒng)是指將轉(zhuǎn)向液壓系統(tǒng)的油引到工作裝置液壓系統(tǒng)，不合流系統(tǒng)是指轉(zhuǎn)向泵的油專門供轉(zhuǎn)向液壓系統(tǒng)。

At present, our loader hydraulic steering system adopts open quantitative pump system, which is characterized by simple structure and sufficient heat dissipation. The steering hydraulic system can be divided into confluence system and non confluence system. Confluence system refers to the hydraulic system that directs the oil from the steering hydraulic system to the hydraulic system of the working device. Non confluence system refers to the oil from the steering pump specially supplied to the steering hydraulic system.

1、流量放大轉(zhuǎn)向

1. Flow amplification steering

轉(zhuǎn)向泵流量優(yōu)先供給轉(zhuǎn)向系統(tǒng)，多余流量合流到工作系統(tǒng)。

The flow of the steering pump is preferentially supplied to the steering system, and the excess flow is combined to the working system.

2、優(yōu)先負(fù)荷傳感轉(zhuǎn)向

2. Priority load sensing steering

轉(zhuǎn)向泵流量優(yōu)先保證通過轉(zhuǎn)向器進入轉(zhuǎn)向油缸，且流量不受轉(zhuǎn)向壓力變化影響，多余流量進入工作或其他系統(tǒng)。

The flow of the steering pump shall preferentially ensure that it enters the steering cylinder through the steering gear, and the flow is not affected by the change of steering pressure, and the excess flow enters the working or other systems.

3、同軸流量放大轉(zhuǎn)向

3. Coaxial flow amplification steering

與優(yōu)先負(fù)荷傳感轉(zhuǎn)向基本相同，區(qū)別僅為轉(zhuǎn)向器不同，進入轉(zhuǎn)向器的流量一小部分通過轉(zhuǎn)向器計量馬達(dá)，大部分（按比例）通過轉(zhuǎn)向器內(nèi)部油道與小部分匯合再進入轉(zhuǎn)向缸。

It is basically the same as the priority load sensing steering, except that the steering gear is different. A small part of the flow entering the steering gear passes through the steering gear metering motor, and most (proportionally) join with a small part through the internal oil passage of the steering gear and then enter the steering cylinder.

二、攪拌裝載機怎么開能省油？

2、 How can the mixing loader be opened to save fuel?

攪拌裝載機是一種大型工程車輛，其油耗較高。如何節(jié)省燃料是許多客戶關(guān)心的話題。

Mixer loader is a large engineering vehicle with high fuel consumption. How to save fuel is a topic of concern to many customers.

使用攪拌裝載機時，攪拌裝載機起步：起步時，可以增加油門以充分發(fā)揮攪拌裝載機發(fā)動機的功能，使攪拌機可以在很短的時間內(nèi)達(dá)到巡航速度，從而達(dá)到節(jié)省燃油的目的。攪拌裝載機

When using the mixing loader, the mixing loader starts: when starting, the accelerator can be increased to give full play to the function of the mixing loader engine, so that the mixer can reach the cruise speed in a very short time, so as to save fuel. Mixing loader

在平坦的道路上行駛時，請盡量在一條車道上行駛，以減少來回?fù)Q車道的發(fā)生，這更有利于攪拌裝載機節(jié)省燃油。如果您乘坐其他車輛行駛，請勿跟隨汽車行駛。通常，跟隨汽車的汽車的油耗會高于前面汽車的油耗?？刂瓢l(fā)動機轉(zhuǎn)速，不同的發(fā)動機有不同的控制轉(zhuǎn)速。在平坦的道路上行駛時，請盡量保持節(jié)氣門開度的穩(wěn)定性。油門應(yīng)該在30％左右。禁止增加和減少油門。

When driving on a flat road, please try to drive in one lane to reduce the occurrence of lane change, which is more conducive to saving fuel for the mixing loader. If you travel in another vehicle, do not follow the vehicle. Usually, the fuel consumption of the car following the car is higher than that of the car in front. Control the engine speed. Different engines have different control speeds. When driving on a flat road, please try to maintain the stability of throttle opening. The throttle should be around 30%. Do not increase or decrease the throttle.
