Abstract
The utility model relates to a high pressure ceramic injection pump used for constant current conveying of corrosive medium in chemical analysis, wherein a pump body comprises a piston, a piston sleeve and a piston rod; the front end of the piston sleeve is provided with a medium conveying pipe joint; the piston and the piston sleeve are made of ceramics; the piston rod which is a screw stem with fixed axial direction and provided with external thread is rotatablely connected with an electric machine through a speed reducer; moreover, the piston rod is connected with a movable nut through screw thread, while the movable nut is connected with a ceramic piston through a connecting component; the ceramic piston is provided with a hollow intracavity for inserting the piston rod. When the piston rod is driven by the electric machine to rotate, the movable nut drives the ceramic piston to slide along axial direction; therefore, medium is output through suction or injection at constant flow rate; moreover, higher conveying pressure can be obtained.
Description
Technical field
The utility model relates to a kind of higfh-tension ceramics syringe pump, is used for chemical analysis the constant current of Korrosionsmedium is carried.
Background technique
Often need to carry Korrosionsmedium in the chemical analysis, at present peristaltic pumps that adopt more.But in some analytical system, online check and analysis system as COD in the water, need carry out constant current to the corrosivity carrier that contains sulfuric acid and potash bichromate carries, be not only corrosion-resistant to the requirement of transfer pump, and need good seal performance, reach higher discharge pressure, constant flow, ripple disable, and peristaltic pump is difficult to reach above requirement.
Summary of the invention
The purpose of this utility model provides a kind of higfh-tension ceramics syringe pump, and the constant current that is particularly useful for Korrosionsmedium is carried, and has fabulous corrosion-resistant and sealing, guarantees that media stabilize flows.
The pump housing of this higfh-tension ceramics syringe pump comprises piston, piston sleeve, piston rod, the front end of piston sleeve is provided with the medium transport interface tube, feature of the present utility model is that piston and piston sleeve are made by pottery, said piston rod is an axial restraint and is provided with externally threaded screw rod, and it links to each other rotatable with motor by retarder, and this piston rod is connected with a travelling nut by screw thread, travelling nut is connected with Ceramic piston by connection part, and Ceramic piston is provided with the hollow cavity that stretches into for piston rod.
The utility model higfh-tension ceramics pump also comprises following feature:
Said connection part comprises and has interior prominent a pair of anchor ear and a metallic sheath, the Ceramic piston outer wall is provided with an annular groove, annular groove and the interior prominent snapping of anchor ear and by anchor ear clamping of said Ceramic piston by being located at outer wall, said anchor ear and metallic sheath link into an integrated entity by bolt and travelling nut.
Piston rod links to each other by a shaft coupling with retarder.
Piston rod is equipped with bearing and bearing support.
The outer stainless steel outer sleeve that is provided with of said Ceramic piston cover.
The pump housing is fixed on the frame.
Said Ceramic piston cover is formed by ceramic body and end plate bonding, and the material of said end plate can be pottery, highdensity macromolecular material material or stainless steel material.
The running-on inwall of said Ceramic piston cover is provided with seal washer.
The piston rod of this ceramicpump is rotated by motor driving, because the piston rod axially locating, during its rotation, the travelling nut that is connected with piston rod produces axial displacement with respect to piston rod, and drive piston simultaneously and in piston sleeve, slide, the piston sleeve internal pressure is changed and medium is sucked or output.
This pump is applicable to the conveying to the small flow Korrosionsmedium, its stability of flow ripple disable, and can reach higher discharge pressure.
