全自动混凝土搅拌车是现代建筑工程中必不可少的机械设备之一,那你知道如果它的油号及油箱设计不合理会如何吗?下面小编为您讲解一番。
Full-automatic concrete mixer truck is one of the necessary mechanical equipment in modern construction engineering. Do you know what will happen if its oil number and tank design are unreasonable? Let's explain it to you.
(1)液压油的油号选用不当,可能造成液压系统的发热所选液压油在油温较低时,系统正常工作,但系统工作一段时间后,油温升高,液压油黏度下降,造成系统内部泄漏增加,伴随泄漏的增加更促使了油温的上升,形成油温的恶性循环。的方法是:根据系统的负载及正常工作温度要求,选择合适黏度的液压油。
(1) Improper selection of the oil number of the hydraulic oil may cause the heating of the hydraulic system. When the oil temperature is low, the system works normally. However, after the system works for a period of time, the oil temperature increases and the viscosity of the hydraulic oil decreases, resulting in an increase in the internal leakage of the system. With the increase of the leakage, the oil temperature increases, forming a vicious cycle of oil temperature. The solution is to select the hydraulic oil with proper viscosity according to the load of the system and the requirements of normal working temperature.
(2)油箱设计不合理,使液压系统散热效果降低系统发热油箱的主要功能是储存液压油,但它同时兼有散热、沉淀杂质、分离水分的作用。油箱设计不合理,主要表现在两个方面:
(2) The design of the oil tank is unreasonable, which reduces the heat dissipation effect of the hydraulic system. The main function of the oil tank is to store hydraulic oil, but it also has the functions of heat dissipation, precipitation of impurities, and water separation. The design of fuel tank is unreasonable, mainly in two aspects:
一是油箱体积设计过小,由于全自动混凝土搅拌车属移动型液压设备,油箱体积一般为液压搅拌车流量的一倍左右,因此,油箱散热面积及储油量均较小;
First, the volume of the oil tank is too small. Because the fully automatic concrete mixer is a mobile hydraulic equipment, the volume of the oil tank is generally about twice the flow of the hydraulic mixer, so the heat dissipation area and oil storage capacity of the oil tank are small;
二是有些油箱在结构上设计不合理,吸油管口和回油管口较近,中间又不设隔板,从而缩短了油液在油箱内的冷却循环及沉淀杂质的路径,甚造成大部分回油直接进入吸油管,使油箱的散热效果降低,油温升高。
Second, some oil tanks are not reasonably designed in structure. The oil suction and return nozzles are relatively close, and there is no partition in the middle, which shortens the cooling cycle of oil in the tank and the path of settling impurities, and even causes most of the return oil to directly enter the oil suction pipe, reducing the heat dissipation effect of the oil tank and increasing the oil temperature.
方法是:适当增加油箱体积,并尽量加大吸油管口与回油管口之间的距离,吸、回油管之间应设置隔板,以确保油箱应有的散热功率。
The solution is to properly increase the volume of the oil tank, and try to increase the distance between the oil suction pipe orifice and the oil return pipe orifice, and set a partition between the oil suction and return pipes to ensure the heat dissipation power of the oil tank.
