S-valve pump with cushioning function and its cushioning method

Abstract

An S valve pump with a buffer function comprises a cylinder, a first main cylinder, a second main cylinder, an S pipe and a compensation cylinder, wherein fluid with solid aggregate is contained in the cylinder; the first main cylinder and the second main cylinder are used for alternately sucking the fluid from the cylinder and alternately discharging the fluid to the S pipe; one end of the S pipe is connected with a middle slurry discharge pipe, and the other end of the S pipe can be in butt joint with the first main cylinder and the second main cylinder alternately; and the compensation cylinder is used for discharging the fluid to an output slurry discharge pipe during intermittent cut-off of the output slurry discharge pipe so that uniform continuous flow can be formed in the output slurry discharge pipe. The S valve pump is simple in structure, and slurry discharge is continuous and uniform.

Description

technical field [0001] The invention relates to a pulsation buffering technology for fluid conveying equipment, in particular to an S-valve pump with a buffering function and a buffering method thereof, and is especially suitable for conveying fluids such as concrete or mortar. Background technique [0002] S valve pump is widely used in concrete, mortar and other fluid transportation with solid aggregates due to its good fluid passage, and its performance is very reliable. Ordinary S valve pumps are generally composed of two working cylinders, one cylinder sucks slurry, and the other cylinder discharges slurry, and the two cylinders are alternately discharged through S valve switching. However, since the switching of the S tube takes a certain amount of time, there will be a certain period of intermittent pumping interruption during the switching period, resulting in impact on the pipeline, especially for some applications that require continuous and uniform flow (such as c...

Problems solved by technology

However, since the switching of the S tube takes a certain amount of time, there will be a certain period of intermittent pumping interruption during the switching period, resulting in impact on the pipeline, especially for some applications that require continuous and uniform flow (such as concrete spraying, mortar spraying, etc.) It cannot achieve the ideal effect, and other buffering methods used in the industry are also difficult to achieve good results for fluids containing aggregates, poor fluidity, and easy to solidify over time (such as concrete, mortar, etc.), and they often pay a huge amount The price, which greatly limits the application field of S-valve pump
