1台HBT60C型拖泵施工过程中高压泵送时,主液压缸行程逐渐变短,但低压泵送时工作正常。1.工作原理拖泵的工作原理如图1所示,液压系统的压力油推动主液压缸和摆阀液压缸做往复运动。由于主液压缸的活塞杆与混凝土输送缸的活塞相连,主液压缸活塞后移时吸料,使得混凝土从料斗中吸入输送缸;主液压缸活塞前推时,混凝土从输送缸经S管阀压送到输送管道。在往复运动下,混凝土源源不断地输送到浇筑点。
1 HBT60C type tow pump during the construction of high-pressure pump, the main cylinder stroke becomes shorter, but low-pressure pump is working properly. 1. Working principle Working principle of the towing pump shown in Figure 1, the hydraulic pressure of the hydraulic system to promote the main hydraulic cylinder and the reciprocating valve reciprocating cylinder. As the piston rod of the main hydraulic cylinder is connected with the piston of the concrete conveying cylinder, the main hydraulic cylinder piston absorbs after the piston moves backward, so that the concrete suctions the conveying cylinder from the hopper. When the main hydraulic cylinder piston pushes forward, the concrete passes through the S pipe valve Pressure delivery to the pipeline. In the reciprocating motion, concrete continuously transported to the pouring point.
