Analysis of hydraulic system composition of mixer truck

Hydraulic mixer means is a key component of the mixer, it promotes normal operation of the mixer, the pressure generated by the hydraulic pump hydraulic oil can be quickly and effectively ejected, complete hydraulic working. The most important part of the hydraulic system of the mixer truck is the oil pump, which is the hydraulic pump, but the hydraulic pump is not fixed. The work of the automatic transmission oil pump drive engine is that the hydraulic pump can accelerate or decelerate the operation, which is what we often say. Reducer.

We know the key components of the hydraulic system hydraulic pump, then what are the key parts of the hydraulic pump configuration? Various radiators, hydraulic oil filter, reducer, hydraulic pump, motor assembly and accessories are all important parts of it. We know that during the working process of the mixer truck, a lot of hydraulic energy will be converted into heat energy. Due to the phenomenon of high body temperature caused by high-speed movement, the friction between components will generate heat, which will cause the oil temperature to overheat. The pump body is overheated and it is easy. The body is damaged and the radiator is dedicated to solving this problem. A good radiator saves the maintenance and maintenance costs of the hydraulic pump. Hydraulic oil filter, as its name implies, is mainly responsible for filtration. Most of the liquids contain sediments or magazines. When entering the filter inlet, the hydraulic oil filter will filter through the different density of the filter layer from the outside to the inside to form a relatively clear liquid, and the debris will be trapped in the filter element. Excluding the discharge through the pipeline will not affect the next step. It is an important preparation process for hydraulic work. In some cases, the speed reducer is also an accelerator, and its important role is to protect the pump and the motor and reduce unnecessary wear in the early stages. The hydraulic pump is the power source of the hydraulic system. According to the individual requirements, the output flow can be adjusted. Because of this difference, the hydraulic pump can be divided into two types: variable pump (flow adjustable) and fixed pump (flow can not be adjusted). The motor is a direct source of power, and almost all mechanical products have motors.

For now, it is. Domestic motor production mainly depends on foreign brands, Rexroth AA2FM80, Rexroth AA2FM90 (Germany) Sau MF22, Sau MF23, Sau O 90M100 (Germany and USA), Eaton 5433, Eaton 6433 (Germany) ARK MF089, ARK MF070 (Italy). Of course, on the other accessories of the mixer , these brands also occupy the vast majority of markets. The rapid development of domestic brands from this aspect is Huade, Guangyan, Liyuan, Yuci and the Yangtze River. The domestic industry started relatively late and the production technology is relatively immature. However, in recent years, the rapid development of state-owned brands has made people feel gratified. The country has completely independent production capabilities.
