Abstract
The utility model relates to an anti-dripping ceramic plunger. The utility model is characterized in that a metal component is connected with a ceramic column by the clamping ring structure; the metal component connected with the ceramic column is provided with two parts of an inner steel core and a metal handle; a clamping ring is installed in the groove of the inner hole of the ceramic column between two parts; the inner steel core is connected with the metal handle by the screw thread; the contact face of the inner steel core, the metal handle, and the inner hole of the ceramic column is coated with the adhesive to prevent the screw loosening. The plunger adopts the mechanical connecting and bonding structure for preventing loosening, which can make the connection reliable so as to reach the purpose of never dripping. In the utility model, the face contacting the medium and the working face are all made of structural ceramic material. Compared with the metal plunger, the ceramic plunger has the characteristics of wear-resistance, corrosion resistance, and erosion resistance. Compared with the existing plunger, the utility model has the characteristics of anti-falling, reliable connection, high strength, and long service life.
Description
The utility model belongs to pump and makes the field, relates to a kind of Drop-proof type ceramic plunger.
The plunger pump of petroleum chemical industry use at present mainly uses metal plunger, general carbon steel surfacing Ni60 or surfacing Ni60 and the cobalt coated tungsten carbide mixed-powder of adopting, hardness can reach HRC60, its wear-resisting property is better than customary quenching steel, but this plunger corrosion-resistant, work under aggressive medium, working life is short.Be head it off, used ceramic plunger to replace metal plunger, a kind of " engineering ceramics is made the axial hydraulic pump of main components " disclosed as Chinese patent 89221860.6, improved the working life of plunger, but this plunger is difficult for making, in addition, existing a kind of ceramic plunger adopts the aluminium oxide ceramics post and metal handle is bonding forms, wear-resistant, decay resistance is better, it is the ideal substitute of metal plunger, but adopted the traditional bonding way of ceramics pole and metal handle, in use exist bonding not firm, caducous problem.
The purpose of this utility model is that the existing ceramic plunger of solution is bonding not firm, and a caducous difficult problem provides a kind of Drop-proof type ceramic plunger.
The purpose of this utility model is achieved like this.All adopt structural ceramics to make with medium surface of contact and working surface in the plunger, use Spring Clip to connect metalwork and ceramics pole, steel core and metal handle two-part in the metalwork that will connect with ceramics pole is designed to, in the groove of the ceramics pole endoporus between these two-part collar is installed, and interior steel core and metal handle by collar by scyewed joint, coated with adhesive on the surface of contact of interior steel core, metal handle and ceramics pole endoporus prevents the loosening of screw thread.This plunger adopts mechanical coupling in conjunction with bonding anti-loosening structure, makes to connect reliably never drop-off.
Concrete solution of the present utility model is:
The active section of plunger is the ceramics pole that has blind hole, earlier interior steel core is put into the endoporus of ceramics pole, then collar is put into the groove of ceramics pole endoporus, earlier fix interior steel core by screw thread, the metal handle of screwing on then, the bottom design of ceramics pole endoporus is become flat side, interior steel core also is with flat side, so just can block interior steel core, be convenient to metal handle energy threaded together, make it can be adjacent to the ceramics pole end face, during work, propelling force is born by the end face of ceramics pole, and pull-back forces bears the groove of ceramics pole endoporus by metal handle by collar.When assembling, all coat epoxyn on the surface of contact of interior steel core, metal handle and ceramics pole endoporus, prevent thread looseness, the traditional ceramics pole of ceramic plunger and the bonding way of metal handle have so just been changed, and adopt mechanical coupling in conjunction with bonding anti-loosening structure, made and connected firmly the Drop-proof type ceramic plunger of never drop-off.
The utility model ceramic plunger is compared with metal plunger has wear-resistant, corrosion-resistant, erosion resistant characteristics, compare with existing ceramic plunger, have Drop-proof, connect reliable, intensity is high, the characteristics of long service life, therefore this plunger is the existing desirable alternative of plunger, has good market prospects.
Fig. 1 is the front view of Drop-proof type ceramic plunger;
Fig. 2 is that the A-A of Fig. 1 is to view;
Further specify the utility model below in conjunction with accompanying drawing.
On the ceramics pole (4) of utilization structure ceramic making, have an endoporus, be used for placing interior steel core (1), and collar (3) is put into the groove of ceramics pole (4) endoporus, steel core in then metal handle (5) being fixed by screw thread and collar, and make metal handle (5) be adjacent to the ceramics pole end face, on the surface of contact of interior steel core (1) and ceramics pole (4) endoporus and metal handle (5) and ceramics pole (4) endoporus, all coat epoxyn (2), can prevent the loosening of screw thread, when being coated with epoxy resin glue, at first cleaning ceramic post endoporus and metalwork, apply then, solidify, in this plunger, used mechanical coupling in conjunction with bonding anti-loose structure, it is reliable that plunger is connected, never drop-off.
