Description

QPQ (quench-Polish-quench) treatment device for valve core and valve sleeve surface of screw drill accessory

Technical Field

The utility model relates to an oil screw rod drilling tool accessory technical field specifically is screw rod drilling tool accessory case valve barrel surface QPQ processing apparatus.

Background

The screw drilling tool is a positive displacement downhole power drilling tool which takes drilling fluid as power and converts liquid pressure energy into mechanical energy, when slurry pumped by a slurry pump flows through a bypass valve and enters a motor, a certain pressure difference is formed at an inlet and an outlet of the motor to push a rotor to rotate around the axis of a stator, and the rotating speed and the torque are transmitted to a drill bit through a universal shaft and a transmission shaft, so that petroleum drilling operation is realized, the accessory is a necessary device for mounting the screw drilling tool and equipment, and the use quality of the accessory plays a very important role.

The existing process adopts a chromium plating process after screw drill fittings are produced. The hard chromium plating process is to plate one relatively thick chromium layer of thickness over 20 microns on the surface of the base and to utilize the characteristic of chromium to raise the hardness, wear resistance, heat resistance, corrosion resistance and other performance of the parts. However, the chromium-plated screw drill fitting still has the problem of poor environmental protection. The working environment of the screw drill fitting is a severe underground corrosive environment, and rust spots and chromium coatings fall off after the screw drill fitting is used for 200 hours. The hard chrome plating process also causes serious environmental problems, the chromic acid solution used in the chrome plating process generates chromium-containing acid mist and waste water, and other disadvantages such as: the hardness is generally 800-900 HV, the hardness is lower than that of some ceramic and metal ceramic materials, and the hardness is reduced along with the temperature rise; the chromium coating has microcracks, which inevitably generates penetrating cracks, so that a corrosive medium permeates from the surface to an interface to corrode a matrix, and rusty spots and even peeling of the surface of the coating are caused; the deposition speed of the electroplating process is low, 2-3 shifts of time are usually needed for plating a plating layer with the thickness of 0.2-0.3 mm, and the application of the thick plating layer is not facilitated.

At present, the surface of the valve core and the valve sleeve is plated with hard chromium to play roles in wear resistance and rust resistance. The surface hardness of the hard chromium can reach more than 800 degrees, and the hard chromium has better wear resistance and certain antirust capability, but the antirust performance of the hard chromium is greatly inferior to that of QPQ (QPQ is the abbreviation of Quench-Polish-Quench in English, namely quenching, polishing and quenching) technology. In addition, even if the cost is much lower than that of hard chrome plating, the QPQ treatment is combined with the tempering treatment, and the surface hardness is comparable to that of the hard chrome plating. Although QPQ has many advantages, currently, there is no special comprehensive equipment, a QPQ process can be realized, a manufacturer often needs to configure a plurality of scattered equipment to complete the QPQ process, and controllability of conditions is poor.
