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、装载机转向系统有哪些特点?
1、 What are the characteristics of loader steering system?
目前我们的装载机液压转向系统采用开式定量泵系统,其特点是结构简单、散热充分。转向液压系统又有合流系统与不合流系统之分。合流系统是指将转向液压系统的油引到工作装置液压系统,不合流系统是指转向泵的油专门供转向液压系统。
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、流量放大转向
1. Flow amplification steering
转向泵流量优先供给转向系统,多余流量合流到工作系统。
The flow of the steering pump is preferentially supplied to the steering system, and the excess flow is combined to the working system.
2、优先负荷传感转向
2. Priority load sensing steering
转向泵流量优先保证通过转向器进入转向油缸,且流量不受转向压力变化影响,多余流量进入工作或其他系统。
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、同轴流量放大转向
3. Coaxial flow amplification steering
与优先负荷传感转向基本相同,区别仅为转向器不同,进入转向器的流量一小部分通过转向器计量马达,大部分(按比例)通过转向器内部油道与小部分汇合再进入转向缸。
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、搅拌装载机怎么开能省油?
2、 How can the mixing loader be opened to save fuel?
搅拌装载机是一种大型工程车辆,其油耗较高。如何节省燃料是许多客户关心的话题。
Mixer loader is a large engineering vehicle with high fuel consumption. How to save fuel is a topic of concern to many customers.
使用搅拌装载机时,搅拌装载机起步:起步时,可以增加油门以充分发挥搅拌装载机发动机的功能,使搅拌机可以在很短的时间内达到巡航速度,从而达到节省燃油的目的。搅拌装载机
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
在平坦的道路上行驶时,请尽量在一条车道上行驶,以减少来回换车道的发生,这更有利于搅拌装载机节省燃油。如果您乘坐其他车辆行驶,请勿跟随汽车行驶。通常,跟随汽车的汽车的油耗会高于前面汽车的油耗。控制发动机转速,不同的发动机有不同的控制转速。在平坦的道路上行驶时,请尽量保持节气门开度的稳定性。油门应该在30%左右。禁止增加和减少油门。
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.
