Device for lowering fluid pulsation impact

Abstract

The invention discloses a device for lowering fluid pulsation impact. The device for lowering fluid pulsation impact is of an inverted-L shape on the whole. The device for lowering fluid pulsation impact comprises a first pipe, a second pipe, a third pipe, a fourth pipe, a fifth pipe and a sixth pipe, wherein the first pipe, the second pipe, the third pipe, the fourth pipe, the fifth pipe and thesixth pipe are sequentially connected and communicate. The axle wires of the first pipe, the second pipe, the third pipe, the fourth pipe, the fifth pipe and the sixth pipe are all located in the sameplane. The first pipe is a horizontal straight pipe. The second pipe is a bent pipe. The third pipe is a vertical straight pipe. The fourth pipe and the fifth pipe are bent pipes. The sixth pipe is avertical straight pipe. The first pipe and the third pipe are connected through the second pipe, the third pipe and the sixth pipe are connected through the fourth pipe and the fifth pipe so that thefirst pipe and the third pipe are perpendicular to each other, and the third pipe and the sixth pipe are parallel with each other. According to the device for lowering fluid pulsation impact, throughan elbow connection manner, vibration load of a liquid input pipeline can be lowered, and the pulsation impact pressure of a liquid in the liquid input pipeline on a volumetric pump is buffered.

Description

technical field [0001] The invention belongs to the technical field of fluid equipment, in particular to a device for reducing the impact force of fluid pulsation. Background technique [0002] In the current light industrial production process, the mechanical equipment for conveying fluid is mainly completed by pumps. Under normal circumstances, if the fluid with a liquid viscosity exceeding 150cP chooses a volumetric pump, there are many types of volumetric pumps, but their common working feature is that the flow rate of the volumetric pump is not adjusted by the outlet regulating valve. The generally used methods are: bypass, The common disadvantages of speed and stroke adjustment are: the periodic change of its volume produces flow pulsation, which causes the discharge flow to be unbalanced, and the impact load of the fluid in the pipeline is relatively large, resulting in friction and loosening of the transmission pipe fittings. To fracture, seriously affecting the con...
