Description
Technical Field
The invention relates to the technical field of a cylinder sleeving pump, in particular to a novel reciprocating type cylinder sleeving pump.
Background
At present, the reciprocating plunger pump is generally adopted for conveying paste materials (coal slime, sludge and gasified fine slag) in China, and the basic structure of the reciprocating plunger pump mainly comprises a pump body (a liquid cylinder), a piston (a plunger), a piston rod, a liquid suction valve and a liquid discharge valve (a one-way valve). Generally, two end points of the piston moving left and right in the pump cylinder are called dead points, and the distance between the two dead points is called a stroke (stroke); the space between the two valves of the piston is called the working chamber. When the piston normally works, the piston continuously reciprocates, the working chamber alternately (discontinuously) sucks liquid and discharges liquid, and energy is transferred to liquid in the form of static pressure energy through the piston. The liquid suction and discharge are changed by the space of the working chamber, so the reciprocating pump is a positive displacement pump. The high-pressure slurry conveying device has the advantages of high conveying pressure, stepless adjustment of conveying capacity, long-distance conveying and the like, is suitable for conveying slurry-presenting materials (such as coal water slurry, slurry and the like) with good suction and fluidity under high pressure, has a wide application range in the field of fluid conveying, and is mainly used for conveying slurry materials such as coal slime and the like in the coal industry.

Therefore, the current solution is to add additional pre-treatment equipment (pre-stirring and water-adding mixing device) to process the pre-treatment equipment into transportable fluid to be pumped into the pipeline, and then to arrange a post-dehydration device at the outlet of the pipeline to process the fluid into a bulk material state before transportation, so that the investment cost of the pre-treatment equipment and the post-treatment equipment in the whole bulk material transportation link is overhigh.
