Water tap test stand apparatus for drilling machine and workover rig

Abstract

The invention discloses a water tap test stand apparatus for a drilling machine and a workover rig. The water tap testing stand apparatus comprises a water tap rotation load test device, a hydraulic pump station, and a test console. The water tap rotation load test device comprises a test stand support, a rotating power machine assembly, and a load rotating device assembly. The load rotating device assembly comprises a load hydraulic cylinder, a coupling head, and a load rotating mechanism. The piston rod of the load hydraulic cylinder is connected with the load rotating mechanism through the flange. The coupling head is disposed on the top of the load rotating mechanism. The hydraulic pump station comprises a pump group and a hydraulic oil tank. The pump group is disposed on the bottom of the hydraulic oil tank. The hydraulic oil tank is connected with a valve plate assembly. The water tap test stand apparatus is reasonable and reliable in structure and may experiment on automatic load and load holding. The stretch and the retraction of the piston rod of the load hydraulic cylinder can be controlled in an inching manner and load can be displayed by an instrument in a visualized manner. The water tap test stand apparatus is easy and convenient to operate and convenient in recording, and greatly reduces labor intensity in test processes.

Description

technical field [0001] The invention belongs to the field of petroleum drilling, and in particular relates to a faucet test bench device for drilling rigs and workover rigs. Background technique [0002] At present, water taps for drilling rigs and workover rigs have been widely used in the field of oil drilling. The safety requirements are extremely high, and once a problem occurs, it will cause safety accidents and huge property losses. According to the regulations of the standard SY / T5530, after the faucet is assembled, it should be subjected to a step-by-step loading test and meet the relevant parameter requirements of the standard SY / T5530. Generally, the test device of the faucet manufacturer adopts the method of manual loading and load preservation for operation test. According to the provisions of SY / T5530, the running test time is at least 3 hours. During the running of the faucet, the contact gap will be reduced or disappeared due to the running-in of the bearing,...

AI Technical Summary

Problems solved by technology

According to the provisions of SY / T5530, the running test time is at least 3 hours. During the running of the faucet, the contact gap will be reduced or disappeared due to the running-in of the bearing, resulting in a drop in the pre-loaded load. It is cumbersome, and the operator needs to be highly concentrated and tired; in addition, the loaded load needs to be calculated by the product of the system pressure and the cross-sectional area of ​​the cylinder, which is also troublesome
