1.原出口法兰结构HBT60S型混凝土拖式泵的输出口主要由出口法兰1、S管2、密封环3、轴承座4、固定板5、端面密封圈6、注油管7等组成,如图1所示。该拖式泵在泵送混凝土时,S管2的入口由液压缸推动,在混凝土输送泵的2个输送缸出口间摆动,以交替输送2个输送缸泵出的混凝土。出口法兰1的出口与混凝土输送管连接,将混凝土输出。S管2沿轴承座4的内孔摆动,其与轴承座4之间采用润滑脂润滑,通过注油管7自动加注润滑脂,也可通过注油管7下端的黄油盅人工
1. The original export flange structure HBT60S-type concrete trailing pump output mainly by the export flange 1, S tube 2, the seal ring 3, the bearing 4, the fixed plate 5, the face seal 6, the oil pipe 7 and other components, As shown in Figure 1. When the trailing pump is pumping concrete, the inlet of the S-pipe 2 is pushed by a hydraulic cylinder and swings between the two delivery cylinders of the concrete delivery pump to alternately deliver the concrete pumped by the two delivery cylinders. The outlet of the outlet flange 1 is connected to the concrete delivery pipe and the concrete is output. S tube 2 along the inner wall of the bearing housing 4 swing, with the bearing 4 between the use of grease lubrication, automatic filling grease through the filler tube 7, but also through the bottom of the filler tube 7 butter cup artificial
