Abstract
The utility model discloses a novel plunger, which comprises a stainless steel plunger rod, wherein the stainless steel plunger rod comprises a small-diameter section and a large-diameter section, and a ceramic plunger pipe is fixedly sleeved on the outer surface of the small-diameter section. The utility model has the beneficial effects that: the novel plunger has wear resistance and corrosion resistance, the service life of a water seal sleeved outside the plunger is prolonged, and the service life of the plunger is also prolonged.
Description
Technical field
The utility model relates to a kind of novel plunger.
Background technique
At present, plunger is the real cored structure of metal, because the working surface of axle is a metal material, so work long hours in liquid environment, the surface of plunger is worn extremely easily and corrodes, and this situation influences the working efficiency of pump greatly.Along with progress of science and technology, although adopt some etch-proof ways, as spraying or coating ceramic coating or metallic material on the metal shaft surface, but because only in metal shaft surface-coated one deck nonmetallic material, nonmetallic coating can not be blocked up, and with metal shaft between be connected insecure easy disengaging, in real work, be worn away easily, so corrosion protection and antiwear effect are unsatisfactory, working life is short, need often to change, this has promptly increased working strength of workers, has also increased cost consumption.
The model utility content
In view of the defective that above-mentioned prior art exists, the purpose of this utility model provides a kind of Corrosion Protection and all extraordinary novel plunger of abrasion resistance properties.
The purpose of this utility model will be achieved by the following technical programs:
A kind of novel plunger comprises the stainless steel plunger rod, and described stainless steel plunger rod is divided into reduced diameter section and enlarged diameter section, the sheathed ceramic plunger pipe that is fixed with of the outer surface of described reduced diameter section.
Further, the reduced diameter section of described stainless steel plunger rod is provided with annular groove, is arranged with seal ring on the described groove.
Further, the port of the reduced diameter section of described stainless steel plunger rod is provided with screw thread, is connected with a plunger nut thread.
Further, described stainless steel plunger rod is arranged with a red copper pad, and described red copper pad is located between described plunger nut and the ceramic plunger pipe.
Further, the external diameter of described ceramic plunger pipe equates with the external diameter of the enlarged diameter section of stainless steel plunger rod.
Further, be provided with the red copper pad between the enlarged diameter section of described ceramic plunger pipe and stainless steel plunger rod.
The beneficial effects of the utility model are: wear-resistant, corrosion-resistant, improved sheathed its outer water seal life-span, and also prolonged self life-span.
Description of drawings
Fig. 1 is the sectional view of the utility model preferred embodiment.
