Abstract
The invention belongs to high temperature, manometric technique field, a kind of high-temperature water cooling dynamic pressure measurement probe is disclosed, probe pole (1), probe (2), sleeve pipe (3), cable (8), cooling water inlet pipe (9), outlet pipe (10) is included；The probe pole (1) and probe head (2) welding, sensor is arranged on probe (2), sensor wire (8) is loaded in probe pole (1), and cooling water inlet pipe (9) and outlet pipe (10) are loaded among probe pole (1) and sleeve pipe (3) space.By setting cooling water inlet pipe (9) outside probe, cooling water sleeve pipe (3) gap and fin (11) contact heat-exchanging, prevent the sensor in probe (2) is heated from occurring temperature drift, even damage, it can further ensure that sensor wire is impaired from high temperature, it is ensured that the accuracy of measurement data.
Description
Technical field
The present invention relates to high temperature, pressure test technical field, particularly a kind of high-temperature water cooling dynamic pressure measurement probe, the present invention
It can effectively prevent the sensor in probe is heated to occur temperature drift, or even damage, can further ensure that sensor wire is exempted from
It is impaired in high temperature, it is ensured that the accuracy of measurement data.
Background technology
In hot environment, during using probe measurement pressure, hot conditions easily make the heated hair of the sensor in probe
Raw temperature drift, or even damage, and sensor wire high temperature is impaired, work can not be completed by directly resulting in probe, bring tired to measurement
It is difficult.In order to reduce the influence of stream field, it is ensured that the accuracy of data, probe stock size is smaller, brought to probe cooling work
It is difficult.
The content of the invention
The present invention solves the technical problem of：A kind of high-temperature water cooling dynamic pressure measurement probe is provided, can solve the problem that and
Sensor when row high temperature is tested in probe is heated to occur temperature drift, or even damages, and sensor wire high temperature is impaired asks
Topic, improves the measurement accuracy of pressure under hot environment.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of high-temperature water cooling dynamic pressure measurement probe, it is characterised in that：Include probe pole (1), probe (2), sleeve pipe
(3), cable (8), cooling water inlet pipe (9) and outlet pipe (10)；Probe pole (1) and probe (2) welding, described sleeve pipe
(3) it is encapsulated in probe pole (1) outside, is furnished with fin (11) with probe pole (1) gap, fin is welded in sleeve pipe
Wall.
2nd, further, end of probe pressure tap can be single hole, diplopore, three holes, four holes, five holes or seven apertures in the human head.
3rd, further, sensor is installed on end of probe, and the number of sensor is consistent with pressure measurement number of perforations, the line of sensor
Cable (8) is set in probe interior, is drawn from probe tails.
4th, further, two water inlet pipes (9) send into cooling water in sleeve pipe (3) and probe pole (1) gap, by with dissipating
Backing (11) exchanges heat, and reduces probe temperature, and discharge by an outlet pipe (10).
5th, further, it is to reduce stream field influence, probe pole (1) external diameter takes 3~8mm, sleeve pipe (3) external diameter takes 6~
12mm, cooling water inlet pipe (9) caliber is less than 2mm, can be used in the less probe of size.
6th, further, fin (11) is distributed on sleeve pipe (3) inwall and exchanged heat with cooling water, and quantity is between 5~8.
The beneficial effects of the invention are as follows：
,, can be effective to carry out timely cooling down to probe pole by setting sleeve pipe outside probe in the present invention
The sensor prevented in probe it is heated occur temperature drift, or even damage, and sensor wire high temperature is damaged the generation of problem；Together
When, after cooling water pipe is installed in sleeve pipe and probe pole gap, the probe rod inner space of probe is not caused
Influence is blocked, influence will not be produced on probe interior air channel, it is ensured that the accuracy of data measured by probe.
Meanwhile, the present invention is simple in construction, and effect significantly, is suitably promoted the use of.
