小型搅拌机增添在工程操纵的特色

来历:http://zhaoyanfilter.com/ 时候:2020-11-18

当小型搅拌机布管垂直高度较高或受园地限定,只靠设置程度管难以均衡背压时,则宜在保送管的锥形管和纵贯管之间设置插管(亦称插阀管),在遏制泵送时封闭插管以防止混凝土回流。当垂直高度较低时,在垂直配管的下端与小型搅拌机之间设置必然长度的程度管,操纵程度管中混凝土与保送管壁间的磨擦阻力来均衡背压。
When the vertical height of pipe laying of small mixer is high or limited by the site, it is difficult to balance the back pressure only by setting horizontal pipe, then it is better to set a cannula (also known as plug valve pipe) between the conical pipe and the straight pipe of the conveying pipe, and close the pipe when the pumping is stopped to prevent concrete backflow. When the vertical height is low, a certain length of horizontal pipe is set between the lower end of the vertical pipe and the small mixer, and the friction resistance between the concrete in the horizontal pipe and the wall of the conveying pipe is used to balance the back pressure.
普通程度管与垂直管的长度比为1:3,且不宜少于15M。当垂直高度很高时,可在垂直管分层中心增添缓冲弯头操纵弯头中混凝土与保送管壁间的磨擦阻力来均衡背压,以防止混凝土回流。
Generally, the length ratio of horizontal pipe to vertical pipe is 1:3, and should not be less than 15m. When the vertical height is very high, the buffer elbow can be added in the middle of the vertical pipe layer, and the friction resistance between the concrete in the elbow and the wall of the conveying pipe can be used to balance the back pressure to prevent the concrete backflow.
须要非分特别注重的是须要按期查验小型混凝土泵车的管道壁厚,发明壁厚磨损较大时,应当即改换,压力较大地位的保送管应一路改换。当垂直向上泵送高度跨越30M时,应将新的、无磨损的或管壁较厚的保送管设置装备摆设在接近泵的一端,由于越接近泵,管道内压力越大。小型混凝土泵车液压阀件的阀芯和阀体资料的差别、热收缩的系数也会差别,阀芯和阀体之间因热收缩而致使阀芯卡死的景象,致使小型混凝土泵车不能普通遏制任务。

Special attention should be paid to the regular inspection of the pipe wall thickness of the small concrete pump truck. When the wall thickness is worn out, it should be replaced immediately, and the delivery pipe at the position with higher pressure should be replaced together. When the vertical upward pumping height exceeds 30m, the new, wear-free or thick pipe wall delivery pipe should be arranged at the end close to the pump, because the closer to the pump, the greater the pressure in the pipeline. The material of valve core and valve body of small concrete pump truck are different, and the coefficient of thermal expansion is also different. The phenomenon of valve core sticking caused by thermal expansion between valve core and valve body causes small concrete pump truck not to work normally.
任务液体的温度降落以后,致使任务液体的黏度降落,小型混凝土泵车泵的泄露增添,泵的现实流量就会变得有所降落;小型混凝土泵车的液压体系发烧以后,任务液体的黏度就会降落,光滑的机能也会降落,加速了液压的元件的磨损,大大地延长了小型混凝土泵车元件的操纵寿命。
When the temperature of the working liquid rises, the viscosity of the working liquid decreases, and the leakage of the small concrete pump truck increases, and the actual flow rate of the pump will decrease; After the hydraulic system of the small concrete pump truck is heated, the viscosity of the working fluid will decrease, and the lubrication performance will also be reduced, which will speed up the wear of the hydraulic components and greatly shorten the service life of the components of the small concrete pump truck.
小型搅拌机呈现发烧,温度降落的环境后,液压体系及其元件的密封件长短常轻易产生蜕变的,进而会致使其弹性变差,密封性变低,严峻者会致使密封生效,增添了泄露的危险;为了保障小型搅拌机送功课的宁静普通遏制,在操纵的进程中要防止产生液压体系发烧的景象,由于其危险是比拟大的。
When the small mixer is heated and the temperature rises, the sealing parts of the hydraulic system and its components are very easy to deteriorate, which will lead to poor elasticity and low sealing. In serious cases, it will lead to seal failure and increase the risk of leakage; In order to ensure the safe and normal operation of small mixer, the phenomenon of heating of hydraulic system should be avoided in the process of use, because its harm is relatively large.
