Abstract
The utility model provides a screw drill motor test platform for testing pressure difference. The utility model is mainly composed of a driving machine, an anti-backward mechanism, a bearing seat, a clamping push assembly, a roller seat and a base, wherein, the components are assembled in order. The utility model has the advantages of reasonable structure and convenient operation, and can be used for testing the sealing pressure difference of screw drill motors for well boring in oil fields.
Description
The utility model relates to a kind of device of testing the screw drilling tool motor seal pressure differential.
Screw drilling tool motor after making or keeping in repair need be done the seal pressure differential test on the screw drilling tool motor testing counter.Holding of original testing counter pushes in the assembly, in two clamp central lower positive and negative screw pair is set, driving wherein by fluid motor, screw rod rotates, thereby make two clamp tighten drilling tool motor or pine card, because this power of holding that holds mode does not act on drilling tool motor center, therefore it is unreliable to hold, and skidding often occurs.In addition, the pin that draws of anti-retrogression mechanism is driven complex structure by hydraulic pressure.
The purpose of this utility model is to overcome the problems referred to above, makes that to hold the drilling tool motor reliably non-slip, simple in structure.
For achieving the above object, the propelling movement assembly that holds of the present utility model is assembled by holding body, post, seat, lead and two clamp, holding body is enclosed within on the post, and two clamp bottoms are enclosed within on the lead, and top can be connected respectively with two fluid cylinders, also can be connected respectively with two screw pairs, can also be connected with fluid cylinder by end clamp, other end clamp are connected with screw pair, for ease of operation, best end clamp are connected with the liquid cylinder piston bar, and other end clamp are connected with the screw rod of screw pair.Hydraulic system is used for the control to fluid cylinder and propelling movement fluid cylinder, in order to make fluid cylinder stable to the power that holds of drilling tool motor, can on the corresponding reversal valve oil-in of fluid cylinder branch road, accumulator be set, also can with being connected of fluid cylinder cylinder bottom end hydraulic fluid port accumulator and hydraulically-controlled one-way valve be set on the branch road at the oil-out of this reversal valve, for raising holds the stability of power, preferably select back one scheme for use.Anti-retrogression of the present utility model mechanism is contained on the bearing support, it by beam, little cover, draw pin and stage clip to assemble, its central sill is fixed on the bearing support, little cover is fixed on the beam.
Advantage of the present utility model is holding reliably of drilling tool motor skidded, and simple in structure, easy to operate.
