Abstract
The invention provides a double-acting type reciprocating pump which comprises a casing, four moving valves and a bypass hydraulic device, wherein a liquid inlet and a liquid outlet are formed in one side of the casing; the casing is divided into an upper case, a middle case and a lower case; the inlet is communicated with the lower case, and the outlet is communicated with the upper case; partition boards are arranged between the upper case and the middle case and between the middle case and the lower case respectively; the four moving valves are arranged in the positions of the two partition boards, symmetrically pairwise, and movably connected with the partition boards; and a liquid inlet and a liquid outlet of the bypass hydraulic device are connected with two sides of the middle case respectively. The double-acting type reciprocating pump provided by the invention is provided with the bypass hydraulic device, so that the stressed direction of the piston rod is changed into radial forces, the service life is prolonged, and energy is saved.
Description
Technical field
The present invention relates to a kind of double-acting reciprocating pump, belong to field of mechanical technique.
Background technique
Existing reciprocating pump, the installation of its piston is installed in the below of Movable valve, and this structure band makes the structure of the power source of piston be generally the crank block type structure, makes crank be subjected to crooked pressure for a long time, and the life-span is lower.
Summary of the invention
The invention provides a kind of double-acting reciprocating pump, this double-acting reciprocating pump can overcome the above defective.This reciprocating pump is provided with the bypass hydraulic pressure installation, makes the stressed direction of piston rod become radial force, and the life-span prolongs, energy saving consumption.
For solving above technical problem, the invention provides following technological scheme: a kind of double-acting reciprocating pump, described reciprocating pump comprises housing, four Movable valves and a bypass hydraulic pressure installation, and housing is provided with the import and the outlet of liquid, and import and outlet all are arranged on a side of housing; Housing is divided into top box, raising middle flask and nowel, and import is communicated with nowel, and outlet is communicated with top box; Be provided with dividing plate between top box and raising middle flask, be provided with dividing plate between raising middle flask and nowel, four Movable valves are distributed on two dividing plate places, and symmetry in twos is connected to flexible connection between Movable valve and dividing plate; The liquid entering hole of described bypass hydraulic pressure installation and liquid outlet are connected the both sides of raising middle flask respectively.
Further, the sectional shape of described four Movable valves is the T font, and the top is arranged on the top in dividing plate hole, and top dimension is greater than the dividing plate bore dia; The bottom is a rhabodoid, gos deep in the hole.
This double-acting reciprocating pump that the present invention relates to, simple in structure, efficient height, long service life.
