Problems solved by technology
[0004] The measurement method in this technical scheme can realize the temperature measurement in the outlet pipe of the Roots pump, and the temperature sensor used in this method has a simple structure; but the temperature sensor used in this scheme is not provided with a corresponding device to absorb the impact of the liquid, Furthermore, the impact of the liquid in the pipeline increases the vibration amplitude of the casing; and the vibration state affects the measurement results of the sensor, so the anti-interference effect is not good

Embodiment approach
[0046] As an embodiment of the present invention, the corrugated plate 51 is provided with a set of rectangular grooves 511 on the corrugated protrusions on one side of the sleeve, and the first roller 52 is installed in the rectangular grooves 511 through the rotating shaft; when in use, the sleeve 1 moves , The corrugated protrusions on the casing 1 squeeze the No. 1 roller 52, and then drive the corrugated plate 51 to squeeze the spring. By setting the No. 1 roller 52 on the corrugated plate 51, the casing 1 can move more flexibly, thereby making the vibration damping module The sensitivity of 5 is higher.
[0047] As an embodiment of the present invention, the damping module 8 includes a support plate 81, a flower-shaped roller 82, and a torsion spring. The flower-shaped teeth on the flower-shaped roller 82 mesh with the corrugated protrusions on the bellows 7, and the flower-shaped roller 82 is in The bellows 7 are arranged staggered around, the flower-shaped roller 82 is ro...

The invention belongs to the technical field of temperature measurement and particularly relates to a Roots pump working temperature measuring method. A temperature sensor applied to the method comprises a sleeve, a thermocouple, a lead, a vibrating cylinder, a vibration damping module, a fixing plate, telescopic rods, a spring, a corrugated pipe, a damping module and a fixing cylinder, wherein the vibration damping module is arranged between the sleeve and an inner wall of the vibrating cylinder and is used for supporting the sleeve and realizing vibration damping of the sleeve, the lead between the corrugated pipe and the fixing plate is sleeved by the spring, one end of the corrugated pipe and an end surface of the vibrating cylinder are connected through hinging a set of telescopic rods, the damping module is arranged between the corrugated pipe and the fixing cylinder, and the damping module is used for supporting the corrugated pipe and making the moving corrugated pipe subjectedto certain damping. The method is advantaged in that side impact is absorbed through the telescopic rods, impact transmitted by the vibrating cylinder is absorbed through the damping module, the temperature is tested by the thermocouple under the condition having no impact and no vibration, and accuracy of the test result is improved.
Description
Technical field [0001] The invention belongs to the technical field of temperature measurement, and specifically is a method for measuring the working temperature of a Roots pump. Background technique [0002] There are many types of sensors. The temperature sensor used at the temperature test point of the outlet pipe of the Roots pump. When used, the sleeve of the temperature sensor is directly inserted into the pipe wall. Due to the large vibration of the Roots pump during operation, the long-term vibration frequency will be affected. Fatigue the root of the temperature sensor's casing, and finally cracks will cause the temperature sensor casing or the root of the casing to break. If resonance occurs in the pipeline, the temperature sensor will be more likely to break at the joint, resulting in a shorter service life of the temperature sensor. [0003] Some technical solutions for measuring the working temperature of Roots pumps have also appeared in the prior art. For example, a...
