Description

Pulser torque test workbench Technical Field The utility model relates to the technical field of rotary valve testing, in particular to a pulser torque testing workbench. Background Rotary valve pulsers are mud pulse signal generators used in the fields of oil drilling, logging, etc., and are mainly used in wireless Measurement While Drilling (MWD) or Logging While Drilling (LWD) systems to transmit downhole data to the surface by controlling the pressure changes of the mud (drilling fluid). The core principle is that the area of a slurry flow passage is changed through the periodical opening and closing of a rotary valve, so that a pressure pulse signal is generated. Testing of torque of rotary valve pulsers is required to verify design parameters, evaluate mechanical reliability. At present, the testing equipment mainly comprises a driving system, a torque sensor, a load simulation device, a control and data acquisition system and a fixing clamp. When the rotary valve pulser to be tested is installed on a test workbench, a torque sensor, a driving motor and a load simulation device are connected, relevant parameters such as target rotating speed, load level and the like are input into a control system according to test requirements, then the driving motor is started to drive the rotary valve pulser to rotate, a loading device applies preset load, the torque sensor monitors and records the torque value output by the pulser in real time, the torque value is transmitted to a data acquisition card for processing, and the data acquisition card converts analog signals into digital signals and sends the digital signals to a computer for further analysis, so that data are obtained. In the prior art, a clamp for fixing a rotary valve usually uses a bench clamp to clamp the rotary valve, but because the outer wall of the rotary valve is of a cylindrical structure, slipping phenomenon easily occurs in the clamping process, and the rotary valve is clamped easily, so that the using effect is affected. Disclosure of utility model The utility model aims to solve the problems that in the prior art, when a rotary valve pulser is clamped, the rotary valve pulser is easy to slip and is damaged by clamping, and provides a pulser torque testing workbench. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a pulser moment of torsion test workstation, includes the workstation body, be provided with test module on the workstation body, still including fixed the setting is in the base of workstation body, wherein, it is provided with a pair of slider to slide on the base, the fixed grip block that is the arc structure that is provided with in slider top, the grip block inner wall is fixed to be provided with the grip pad, just be provided with on the base and be used for driving the gliding drive division of slider, when drive division during operation, a pair of slider is close to each other or keeps away from.
