Description
Technical field
The invention belongs to diaphragm pump technical fields, and in particular to a kind of left and right propulsion sap cavity of diaphragm pump.
Background technique
It promotes sap cavity for connecting chamber of septum and power end, and supports cylinder sleeve so that the piston in cylinder sleeve completes reciprocal fortune
It is dynamic, it is that membrane pump fluid end realizes one of ore pulp sucking and most critical components of discharge, major function is to pass through shoring
The enlarged bore piston completion reciprocating motion so that in cylinder sleeve is covered, propulsion liquid oil between propulsion liquid chamber internal piston and diaphragm is passed through
The reciprocating motion of diaphragm is completed in flowing with compression, to complete ore pulp compression, realizes ore pulp sucking and discharge.The sucking of ore pulp and
Discharge, makes the intracavitary operating pressure of propulsion liquid that periodical alternating characteristics be presented, and left and right propulsion sap cavity easily generates casting in corner
Defect leads to fatigue crack and fracture accident, and propulsion liquid oil is caused to leak, and diaphragm pump scram will guarantee in the design phase
Left and right propulsion sap cavity corner shape is reasonable, while meeting castability and fatigue strength requirement.
With the continuous improvement of diaphragm pump downstream industry production capacity, (diaphragm pump is referred to diaphragm pump single device conveying capacity
Feed flow and operating pressure) more stringent requirements are proposed, and big flow diaphragm pump is more advantageous under compared to small flow diaphragm pump
Industry of parading improves production efficiency, simplifies production procedure, reduces capital expenditure and operation maintenance cost etc., and meeting country, " energy conservation subtracts
Therefore the fundamental state policy of row " improves the inexorable trend that separate unit diaphragm pump capacity is diaphragm pump future development.
For diaphragm pump there are three sap cavity is promoted, left propulsion sap cavity couples left chamber of septum and power end, right propulsion with " Z " font chamber
Sap cavity connects right chamber of septum and power end with " S " font chamber, and left and right propulsion sap cavity is arranged in symmetric relation.With left propulsion sap cavity
For, the Liang Ge corner structure of " Z " font chamber shape has following features: 1) the left riser for promoting sap cavity in chamber of septum interface and
Power end interface, two turnings and riser distance are farther out, it is difficult to guarantee the castability of casting corner；2) two turnings are
The curving of castings, since difficulty of processing is larger and undressed, easily generation fatigue fracture；3) two turnings are in the diaphragm pump course of work
The load of receiving is alternating stress load, including the pulling force from chamber of septum interface and power end interface, and carrys out self-propelled
The pressure of liquid oil；4) two turnings are easy to happen stress concentration.The above feature of two corner structures determines, left and right propulsion
Two corner structures of sap cavity be easy to happen due to casting flaw and stress concentration, caused by fatigue crack initiation and fracture accident,
Therefore, in the left and right propulsion sap cavity schematic design phase, left and right propulsion two turning castabilities of sap cavity are must satisfy one
Item casting design objective.
As separate unit diaphragm pump capacity is continuously improved, left and right two turning castabilities of propulsion sap cavity become a protrusion
Technical risk point.Currently, many kinds of measures has been used to improve left and right two turning castabilities of propulsion sap cavity: including that will promote
Sap cavity turning to the cavity wall thickness between riser thickeies, MOLTEN STEEL FLOW effect when improving casting；Add at two corner structures
Muscle；Sap cavity is promoted to use better founding materials etc..The above method is unsatisfactory to the improvement of corner's castability, reaches
Less than requirement, the development of big flow diaphragm pump is constrained.
Summary of the invention
The present invention addresses the above problem, provides a kind of raising propulsion two corner's castability of sap cavity, reduces by two
Corner's stress makes it meet the left and right propulsion sap cavity of the diaphragm pump of the requirement of diaphragm pump.
To achieve the above object, the present invention adopts the following technical scheme: the present invention includes cavity, cavity lower half is lower part
Type chamber, the cavity upper half are top type chamber, and overpressure protection system interface is provided on the type chamber of top, and cavity one end is power termination
Mouthful, the cavity other end is chamber of septum interface, it is characterised in that: the upper surface the top Xing Qiang is provided with to be connect with overpressure protection system
The adaptable lower processing plane of mouth；The top type chamber, which is located above power end interface, is provided with processing plane, it is described on
Portion's type chamber is set as vertically casting face close to the corner of power end interface, and upper processing plane and vertically casting face pass through upper inclination
By rolling oblique machined surface transition between machined surface transition, upper inclination machined surface and upper processing plane and lower processing plane.
As a preferred solution of the present invention, the angle between the upper inclination machined surface and horizontal plane is 30 ° ± 5 °；
The angle rolled between oblique machined surface and horizontal plane is 20 ° ± 5 °.
It is had the advantages that compared with existing well-known technique using technical solution of the present invention.
1, each position castability of propulsion sap cavity of the present invention especially corner's castability improvement effect is very aobvious
It writes, to substantially increase reliability, the safety that it is used.
2, the weight of the present invention for promoting sap cavity is increased slightly, the simple easy processing of the increased machined surface of upper half type chamber.
3, the present invention is on the basis of overpressure protection system interface position is constant, by original propulsion sap cavity top type chamber
Round and smooth casting surface is changed to the machined surface of more plane compositions, after increasing riser on the type chamber of the upper half, can use processing
Mode removes riser.
