Abstract
A kind of plunger for reciprocating pump, comprise the plunger body of the hollow be made up of carbon steel, plunger body is the overall plunger formed by Rotary-table and cylindrical body, stainless steel external bushing is arranged with outside plunger body, stainless steel external bushing is made up of stainless steel body and the stainless steel base plate being welded in stainless steel its bottom, and the Stainless Steel Tube end of body of plunger body and stainless steel external bushing is welded to connect.The plunger for reciprocating pump that the utility model provides, can solve plunger maintenance difficult, changes frequent and that cost is high problem, realizes plunger body and recycle, significantly reduce making and maintenance cost, save production cost and metals resources.
Description
Technical field
The utility model relates to a kind of plunger, especially a kind of plunger for carrying containing Korrosionsmedium reciprocating pump.
Background technique
Reciprocating pump is the important manufacturing mechanism of of fertilizer industry, be generally used for for conveying containing Korrosionsmedium, and plunger is one of significant components of reciprocating pump.At present, the plunger of general reciprocating pump adopts stainless steel to make body, simultaneously in order to reduce its friction factor and corrosion resistance, at its plated surface last layer crome metal usually.Because plunger reciprocates frequency is high, wearing and tearing are very fast, plunger maintenance difficult, change frequent, the cost of plating chromium relatively high (very nearly the same with the expense buying new plunger), will increase cost of production so simultaneously, the plunger simultaneously worn and torn leaves unused, and causes the wasting of resources.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of plunger for reciprocating pump, plunger maintenance difficult can be solved, change frequent and that cost is high problem, realize plunger body and recycle, significantly reduce and make and maintenance cost, save production cost and metals resources.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of plunger for reciprocating pump, comprise the plunger body of the hollow be made up of carbon steel, plunger body is the overall plunger formed by Rotary-table and cylindrical body, stainless steel external bushing is arranged with outside plunger body, stainless steel external bushing is made up of stainless steel body and the stainless steel base plate being welded in stainless steel its bottom, and the Stainless Steel Tube end of body of plunger body and stainless steel external bushing is welded to connect.
Plunger body is the plunger that plunger surface does not have the carbon steel of plating chromium and makes.
The thickness of stainless steel external bushing is 3-5 millimeter.
The plunger for reciprocating pump that the utility model provides, adopt the plunger body that surface does not have the carbon steel of plating chromium to make, outside sheathed stainless steel external bushing, when the working surface wearing and tearing of stainless steel external bushing, by stainless steel lining stainless steel external bushing, again outer casing stainless steel external bushing, the object that plunger body is recycled can be reached, reduce significantly to reduce simultaneously and make and maintenance cost, save production cost and metals resources.Use through reality, a plunger body has reached more than 1 year service time, changes the processing and fabricating expense of a stainless steel external bushing and is only 1/5 of new plunger, and plunger is 1.5 times of new plunger service time, cost-saving Be very effective.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of plunger for reciprocating pump, comprise the plunger body 1 of the hollow be made up of carbon steel, plunger body 1 is the overall plunger formed by Rotary-table and cylindrical body, stainless steel external bushing is arranged with outside plunger body 1, stainless steel external bushing is made up of stainless steel body 2 and the stainless steel base plate 3 be welded in bottom stainless steel body 2, and plunger body 1 is welded to connect with stainless steel body 2 end 4 of stainless steel external bushing.
The plunger that plunger body 1 does not have the carbon steel of plating chromium to make for plunger surface.
The thickness of stainless steel external bushing is 3-5 millimeter.
After processing plunger body 1, stainless steel body 2 and stainless steel base plate 3, by press machine, plunger body 1 is pressed in stainless steel body 2, plunger body 1 and stainless steel body 2 end 4 are welded to connect, stainless steel base plate 3 is welded in bottom stainless steel body 2, and the working surface of stainless steel body 2 is machined to required friction factor by grinding machine; When stainless steel body 2 working surface weares and teares, removed by stainless steel body 2 car through lathe, the Stainless Steel Tube (identical with former machining process for plunger) that replacing one is supporting again, plunger body 1 can reuse.
