Technical field
The utility model is related to a kind of metering pumps, and in particular to a kind of for conveying containing diamond dust and hard particles fluid
Wear-resisting metering pump.
Background technology
Fluid containing diamond dust is applied mostly in carborundum electroplating equipment, as emery grinding wheel, sand line, wire cutting molybdenum
In the production equipments of products such as silk, but since electroplate liquid has stronger corrosivity, in addition the abrasion of diamond dust.General machine
Tool pump is auxiliary all not to be adapted to, inadequate use cause short life, maintenance cost be high, maintenance difficulty greatly, cause irregular stop
The unfavorable factors such as production.This is also a great problem on diamond dust electroplating device, and it is even more impossible to meet the needs of automated production.In addition,
Fluid such as containing coal dust and sand powder hard particles also belongs to the example of the range.
Utility model content
For problems of the prior art, the purpose of design of the utility model is to provide a kind of for conveying containing gold
The wear-resisting metering pump of emery and hard particles fluid.
It is described a kind of for convey the wear-resisting metering pump containing diamond dust and hard particles fluid, including pump head, be arranged and exist
The pump head connection cover at pump head cavity end, the Outlet check valves for being symmetricly set on pump head both sides and import check valve, it is characterised in that
It is provided with diaphragm, diaphragm fixing bolt, Protective nut in cavity between pump head and pump head connection cover, is driven mandril, the film
One end of piece fixing bolt is connect with Protective nut, and the other end is fixed after passing through diaphragm with the one end for being driven mandril, and mandril is driven
The other end stretch out pump head connection cover, the diaphragm is made of plane and arcwall face, and plane is located at the centre of disk, center
Arcwall face is provided on the outside of position, the arcwall face is outward extended with edge part, and the edge part is connect with pump head.
Described is a kind of for conveying the wear-resisting metering pump containing diamond dust and hard particles fluid, it is characterised in that the film
Piece is additionally provided with diaphragm reinforcing plate close to the side of pump head connection cover.
Described is a kind of for conveying the wear-resisting metering pump containing diamond dust and hard particles fluid, it is characterised in that the film
Piece reinforcing plate is coaxial arrangement with diaphragm, and the diaphragm reinforcing plate is in the form of annular discs.
It is described a kind of for conveying the wear-resisting metering pump containing diamond dust and hard particles fluid, it is characterised in that it is described go out
Mouth check valve and import check valve are face leakproof one-way valve.
Described is a kind of for conveying the wear-resisting metering pump containing diamond dust and hard particles fluid, it is characterised in that the pump
The cavity of head is in bowl-shape.
The structure design of the utility model is reasonable, and the diaphragm structure by setting and the cavity geometry to pump head are improved,
Ensure that cavity fluid does not stay dead angle, reduces and worn caused by precipitation, meanwhile, by the way that import check valve and Outlet check valves is equal
It is arranged to surface seal structure, through agreement with experimental fluid behaviour, requirement can be better met, prolonged the service life.
