How to install the pressure gauge electronic thermostat

the installation position of the barometer should conform to the regulations of the installation situation. the instrument professional digital thermostat wholesale plate should be vertical in general, and the position should be suitable for workers to observe, also brand number Thermostat wholesale font> tightness, there must be no leakage condition.

during the whole installation process wholesale of high-precision digital thermostats the following many problems should be paid attention to:

(1) selection of pressure port parts: one is to make the sampling pipe and the material flow direction vertical to each other, and to prevent the selection of gate valves, forks and elbows in areas where vortex is very easy to occur; Second, when there are protrusions in the pipeline, the pressure taking port should be selected in front of them. Third, when accurately measuring the working pressure of liquid and steam, the pressure taking point should be built on the lower outer wall of the horizontal pipeline so that no steam can be found in the pressure pipe, prevent residues in the pipeline from blocking the sampling branch pipe; Fourth, the barometer for accurately measuring liquid and vapor substances * should be installed under the instrument panel in the car to prevent liquid or solidified liquid from being placed on other instrument panels.

(2) paving of pressure induction pipes: the function of pressure induction pipes is to transmit working pressure data signals in the middle of the barometer after the pressure taking point. attention should be paid to paving: first, the nominal diameter of pressure induction pipes is generally 6~10mm and the length is less than 50mm, so as to reduce measurement deviation and prevent the marking delay time of barometer caused by material backwardness; Second, the level section connecting the hose should have a certain slope, should maintain 1:10~1:20 slope, in order to facilitate the tube condenser liquid or vapor discharge, the third is the pressure pipe should be equipped with a protective valve, easy to repair the barometer application.

(3) the installation aspect ratio is clear: the installation aspect ratio should be suitable for the staff to observe and check, and should be flush with the average person's vision, I .e. 1.5m ~ 1.6m, and the high working pressure should be higher than the average person's brain, I .e. 1.7m ~ 1.8m up and down. When the vertical distance between the installation part of the barometer and the pressure measuring point is quite large, the liquid column difference should be adjusted. The adjusted standard value is equivalent to the working pressure value caused by the liquid column in the hose with the difference of vertical aspect ratio between the instrument panel and the pressure measuring point. When the instrument panel is higher than the pressure measuring point, this adjustment value shall be added; conversely, when the instrument panel is less than the pressure measuring point, this value shall be subtracted.

(4) Application of sealing gasket: In order to ensure airtightness, a suitable sealing gasket should be selected for the airtightness between the connection head of the barometer and the table seat. When the operating temperature and working pressure are less than 80 ℃ and 2MPa, leather gasket or plastic rubber gasket shall be required. Rock wool, glass magnesium paper or aluminum pad shall be used below 80 ℃ ~ 45 ℃ and 5MPa. When the operating temperature and working pressure are higher, quench copper pad or lead pad shall be used.

sand remover should be used to solve the problem of aggravating drilling fluid, but several inch sand remover with particle size distribution over 74μm must be used. Because the ground settlement straight longitude ratio of barite powder to drill cuttings particles is about 1:1.5, the desander of drill cuttings particles of about * * 74 μm can also remove barite powder of about 49 μm. In barite powder, these particulate matters account for approximately 10%–15%. After this kind of desander has carried out preparatory treatment, the drilling fluid is further into the sludge cleaner, which can greatly alleviate the burden of the sludge cleaner. The defect is that a part of barite powder with large particle size distribution suffers some damage.
