Abstract
The utility model relates to a high wear-resistant piston of a three cylinder mud pump for drilling, which is an improvement of the existing rubber piston; the high wear-resistant piston of the three cylinder mud pump for drilling is characterized in that the outer surface of a hollow rubber ring body (1) with a trapezoidal cross section is coated with a high polymer wear-resistant film layer (2), and the bottom part on one end of the high polymer wear-resistant film layer (2) with small diameter is provided with a nylon reinforcing ring piece (3). Compared with indexes of the high wear-resistant piston of three cylinder mud pump for drilling and the indexes of the existing rubber piston, and the indexes of the high wear-resistant piston of the three cylinder mud pump for drilling can be improved; the friction coefficient of the high wear-resistant piston of three cylinder mud pump for drilling is a quarter of the friction coefficient of the primary product; the high wear-resistant piston of three cylinder mud pump for drilling has the advantages of wear resistance, acid resistance, aging resistance, oil resistance, etc. favorable performance, and wide work temperature range; the service life can reach more than 400 hours.
Description
The utility model relates to the used piston of a kind of drilling mud pump, is specially adapted to the drilling well triplex mud pump.
Slurry pump is the very high facility of drilling industry utilization rate.The existing used piston of slurry pump all adopts single rubber material to make, and the friction factor of piston is big, wear-resisting and poor corrosion resistance, and material is easily aging, and working life is short, needs often to change, and has increased cost of production greatly, has reduced manufacturing efficiency.
At the problem of above-mentioned existence, the utility model proposes the new-type mortar pump piston that a kind of wear-and corrosion-resistant ageing-resistant performance all is greatly improved.
The technical solution of the utility model is achieved in that
One hollow and outer surface that cross section is trapezoidal rubber ring body approximately has an annular wearing layer, has a nylon to strengthen ring plate in the less bottom portion of rubber ring body diameter.
Above-mentioned annular wearing layer is a high molecular polymer wear-resistance thin film layer, and the thickness of this wear-resistance thin film layer is 0.1mm～10mm.
Above-mentioned high molecular polymer wear-resistance thin film layer is for can glue the filled polytetrafluoroethylene thin layer.
Owing to adopted the high molecular abrasion-proof material, make every index of mud piston obtain bigger raising, the friction factor of this product is about 0.15, it only is 1/4th of rubber product, wear-resisting property is good, simultaneously its acid resistant alkali, oil resistant, performance such as ageing-resistant are good, can use for a long time under-100～+ 200 temperature conditions, reach working life more than 400 hours.
Description of drawings: Fig. 1 the utility model structural representation
1 rubber ring body, 2 high molecular polymer wear-resistance thin film layers, 3 nylon are strengthened ring plate
Embodiment of the present utility model below is described:
In the manufacture process of existing rubber piston ring body (1), remove 15% carbon black in the used material, add with the high-molecular polythene of amount mixing simultaneously, with its sulfidization molding be hollow and cross section be trapezoidal rubber piston ring body (1) approximately before, add thick the glued filled polytetrafluoroethylene thin layer (2) of one deck 5mm at outer surface, under+140 temperature, vulcanize moulding in 30 minutes then, and add nylon reinforcement ring plate (3) gluing of rubber piston ring body (1) than minor diameter one bottom portion.
Claims (3)
1, a kind of drilling well triplex mud pump high abrasion piston, it is improvement to existing rubber piston, it is characterized in that a hollow and the cross section outer surface that is trapezoidal rubber ring body (1) approximately one annular wearing layer (2) is arranged, have a nylon to strengthen ring plate (3) in the less bottom portion of the diameter of rubber ring body (1).
2, drilling well triplex mud pump high abrasion piston according to claim 1 is characterized in that described annular wearing layer (2) is a high molecular polymer wear-resistance thin film layer, and the thickness of this wear-resistance thin film layer is 0.1mm～10mm.
3, drilling well triplex mud pump high abrasion piston according to claim 2 is characterized in that above-mentioned high molecular polymer wear-resistance thin film layer (2) is to glue the filled polytetrafluoroethylene thin layer.
