Abstract
The utility model discloses a ceramic pump comprising a metal outer sleeve, wherein, a ceramic inner sleeve is arranged in the metal outer sleeve, the ceramic inner sleeve and the metal outer sleeve are in interference fit, a liquid inlet pipe and a liquid outlet pipe are arranged on the ceramic inner sleeve and the metal outer sleeve, plungers are arranged in the ceramic inner sleeve, through holes are formed on the plungers, and a pull rod is arranged at one end of each plunger. The ceramic pump is made of ceramic materials, utilizes the interference fit of the ceramic inner sleeve and the metal outer sleeve, simultaneously uses the ceramic upper plunger and the ceramic lower plunger and has the properties of high hardness, abrasion resistance, high temperature resistance and corrosion resistance; furthermore, the ceramic plunger, the ceramic inner sleeve and the plunger matched with the ceramic inner sleeve play the role of self-lubrication, and the mechanism of sliding friction andlubrication of the traditional plunger pump is changed. The surface of an inner cavity of the ceramic inner sleeve and the external surfaces of the plunger matched with the ceramic inner sleeve and the lower plunger adopt mirror surfaces processed by an internal and external grinding machine, thereby facilitating cleaning and disinfection.
Description
Technical field
The utility model relates to a kind of pump, specifically the plunger pump that makes with the employing stupalith.
Background technique
In industries such as medicine, Environmental Engineering, oil, chemical industry, the application of plunger pump is more extensive.Mostly existing plunger pump is metal pump, and the hardness of metal pump is low, and wear-resisting, poor corrosion resistance, and non-refractory easily pollute.Because there is above-mentioned deficiency in metal pump, the working life of metal pump is low, through regular meeting's stopping production maintenance or replacing metal pump, has increased unnecessary expense, thereby has improved cost of production in the using process.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned deficiency a kind of ceramicpump is provided, and has solved that metal pump hardness is low, wear-resisting, the technical problem of corrosion-resistant, reduces the number of times of changing pump simultaneously, has saved cost of production.
The technical solution of the utility model is:
A kind of ceramicpump comprises metal-coating, establishes cover in the pottery in the metal-coating, cover and metal-coating interference fit in the pottery are provided with liquid inlet pipe and drain pipe on cover and the metal-coating in pottery, in the cover plunger is set in pottery, plunger is provided with through hole, is provided with pull bar at an end of plunger.
Above-mentioned ceramicpump, described plunger has upper plug and lower plunger, and the upper end of upper plug is welded with upper connecting rod, and the lower end of lower plunger is welded with lower link, and through hole is arranged on the upper plug.
Above-mentioned ceramicpump, described plunger is a ceramic plunger.
Above-mentioned ceramicpump, described metal-coating are the stainless steel metal overcoats.
Internal surface that overlaps in the above-mentioned ceramicpump, described pottery and the minute surface that is internal and external grinding machine processing with the interior outer surface that overlaps the plunger that matches of pottery.
The utility model adopts stupalith, utilize cover and metal-coating interference fit in the pottery, use ceramic upper plug and ceramic lower plunger simultaneously, have hardness height, wear-resisting, high temperature resistant, corrosion resistant performance, ceramic plunger has self-lubricating function with interior cover of pottery and plunger with matching, has changed traditional plunger pump sliding friction and lubricated mechanism.The surface of internal cavity that overlaps in the pottery and the plunger and the lower plunger outer surface that match with the interior cover of pottery are the minute surfaces of internal and external grinding machine processing, conveniently clean, sterilize.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of upper plug and upper connecting rod;
Fig. 3 is that Fig. 2 A-A is to view.
Embodiment
A kind of as shown in drawings ceramicpump, comprise metal-coating 6, establish cover 5 in the pottery in the metal-coating, cover 5 and metal-coating 6 interference fit in the pottery, cover 5 constitutes ceramic pump chamber in the pottery, in pottery, be provided with liquid inlet pipe 4 and drain pipe 2 on cover and the metal-coating, liquid inlet pipe 4 and drain pipe 2 are connected with ceramic pump chamber 10, in pottery, in the cover 5 plunger is set, described plunger has upper plug 3 and lower plunger 7 to constitute, and the upper end of upper plug 3 is welded with upper connecting rod 9, and upper plug is provided with through hole 1, through hole 1 is connected with ceramic pump chamber 10, the lower end of lower plunger 7 is welded with lower link 8, and described plunger is a ceramic plunger, and lower plunger is a ceramic plunger, metal-coating is the stainless steel metal overcoat, and the internal surface of cover and the upper plug that matches with cover in the pottery and lower plunger outer surface are the minute surfaces of internal and external grinding machine processing in the pottery.
Working procedure is as follows: upper connecting rod 9 and lower link 8 are connected respectively on the different motors, the last ceramic plunger 3 of upper connecting rod 9 drives rotates in ceramic pump chamber during work, align with liquid inlet pipe 4 when the lateral aperture of through hole 1, lower plunger 7 moves downward simultaneously, and liquid is pumped in the pump chamber 10; Last ceramic plunger 3 is backward rotation again, and ceramic plunger 7 is boosted under the lateral aperture of through hole 1 is alignd with drain pipe 2, and while lower link 9 drives, liquid is released, thus the transmission of realization liquid.
Wherein the angle between liquid inlet pipe and the drain pipe can determine according to pump speed, 60 degree, 90 degree, 120 degree and 180 degree are arranged, it is high when hour pump speed of the angle between liquid inlet pipe and the drain pipe can be bigger than angle, the motion of upper plug is not 360 degree rotations, axially back and forth rotate but do 60 degree, 90 degree, 120 degree or 180 degree, also can be understood as left-right rotation.
Claims (5)
1, a kind of ceramicpump, comprise metal-coating, it is characterized in that: establish cover in the pottery in the metal-coating, cover and metal-coating interference fit in the pottery, in pottery, be provided with liquid inlet pipe and drain pipe on cover and the metal-coating, in overlapping in pottery plunger is set, plunger is provided with through hole, is provided with pull bar at an end of plunger.
2, ceramicpump according to claim 1 is characterized in that: described plunger has upper plug and lower plunger, and the upper end of upper plug is welded with upper connecting rod, and the lower end of lower plunger is welded with lower link, and through hole is arranged on the upper plug.
