The invention relates to the technical field of rotating speed detection, and discloses a rotating speed and rotating direction detection device of a high-temperature and high-pressure shielding electric pump, which comprises a bearing sleeve, a driving shaft sleeve is fixedly mounted at one end of the bearing sleeve, and a detection device is fixedly mounted at one end of the driving shaft sleeve. An image phase presented by an induced current generated by a magnetoelectric sensor I is ahead of an image phase presented by an induced current generated by a magnetoelectric sensor II by 90 degrees. If a reverse rotation condition occurs, the image phase presented by the induced current generated by the magnetoelectric sensor II is ahead of the image phase presented by the induced current generated by the magnetoelectric sensor I, so that an operator can quickly judge whether the equipment is in a reverse rotation change or not, the problem that due to the fact that static sealing is adopted for a shield pump, the operator cannot directly observe the rotating direction of an internal rotating shaft, reverse rotation cannot be found in time, and a pump body is damaged is solved, and the practicability of the device is improved.
Description
Technical field [0001] The present invention relates to a speed detection, and in particular the steering speed detecting means is a high-temperature high-pressure pump of the shield. Background technique [0002] High temperature and high pressure pump is a canned motor pump with full static seal type pump, and the pump drive motor are pumped medium is sealed in a pressure vessel filled by a rotating magnetic field and the electric wire is provided to drive the rotor, this structure cancel the rotation shaft seal having the conventional centrifugal pumps, can not be completely leak, the liquid used in the high temperature and pressure, or nuclear waste transport operation having high volatility liquids having a simple structure, low cost, high sealing performance advantages . [0003] Conventional high temperature and pressure although the canned motor pump has many advantages, it still has some limitations in actual use, since the sealing state in a fully static, the rotational...
