The utility model discloses a pneumatic cylinder because its delivery pressure is big, under the condition with the bore, can obtain bigger flow and higher lift, and maintain the convenience as the drive assembly of diaphragm pump.
Description
Technical field
The utility model relates to diaphragm pump field, more particularly, is a kind of hydraulic high-pressure diaphragm pump.
Background technique
Membrane pump with pneumatic drive is a kind of novel liquid material transfer equipment, the use of the equipment such as alternative submersible pump, pollution discharge pump, centrifugal pump.Little for volume, lightweight, the easy to install feature such as flexibly of this pump.Because it can carry solids-laden fluid, there is not the advantages such as the problem of explosion-proof aspect, generally use in the increasing industry such as petrochemical industry, coating, boats and ships, water treatment, food, papermaking, mine.
Because the membrane pump with pneumatic drive performance characteristic pressure that is input bleed pressure and output medium is approximately the relation of 1:1, and the compressed-air actuated pressure that generally air compressor provides is 8kg/cm
2, therefore the delivery pressure in the outlet port of membrane pump with pneumatic drive is about 8kg/cm
2.Under the occasion needing more high output pressure, membrane pump with pneumatic drive can not satisfy the demands.
Model utility content
In order to solve the problems referred to above that prior art exists, the purpose of this utility model proposes a kind of hydraulic high-pressure diaphragm pump, and it adopts oil hydraulic cylinder to substitute Pneumatic motor assembly as power source, completes the scheme that high pressure exports.
For achieving the above object, the utility model is solved by following technological scheme:
A kind of hydraulic high-pressure diaphragm pump, comprise the piston in diaphragm pump main shaft, diaphragm pump inner splint, the hydraulic cylinder of coupling and the hydraulic cylinder at its two ends and described hydraulic cylinder, described hydraulic cylinder is fixed on column, described diaphragm pump main shaft imbed coupling in piston fixing after, the axis hole that two ends passes described two hydraulic cylinders respectively fixes rubber membrane; Described hydraulic cylinder is fixed respectively diaphragm pump inner splint described in.
As preferred technological scheme:
Hydraulic high-pressure diaphragm pump described in the utility model, the contact position of described piston upper piston and described diaphragm pump main shaft is fixed with inner panel by hex head bolt.
Hydraulic high-pressure diaphragm pump described in the utility model, the two ends of described rubber membrane are respectively equipped with protects block, and itself and described rubber membrane are bolted on described diaphragm pump main shaft.
Hydraulic high-pressure diaphragm pump described in the utility model, the two ends that described piston contacts with described hydraulic cylinder are provided with some seal grooves, are respectively arranged with y-shaped ring in sealing ring recess.
Hydraulic high-pressure diaphragm pump described in the utility model, described diaphragm pump main shaft overlaps respectively with described piston contact position and has an O-ring seals.
Hydraulic high-pressure diaphragm pump described in the utility model, described inner splint hex head bolt is fixed on described hydraulic cylinder.
Hydraulic high-pressure diaphragm pump described in the utility model, the sealed hub of described rubber membrane embeds in the seal groove of described column; And the outside of described diaphragm pump inner splint is screwed on described column.
Owing to adopting above technological scheme, the utility model have employed oil hydraulic cylinder as after the driven unit of diaphragm pump, because its delivery pressure is large, when same bore, can obtain larger flow and higher lift, and easy to maintenance.Because delivery pressure increases, the scope be suitable for is also larger, can meet the demand of special occasions, increase economic benefit.
