Product Description

Made in china MC 1.6  -40-180℃ negative pressure gauge meter Y250BF using in oil gas water

Introduction

Pressure gauge (English name: pressure the gauge) refers to elastic element as the sensitive element, measure and instructions above environment pressure meter, the widespread application, it almost throughout all of the industrial process and research fields. In the heat pipe network, oil and gas transmission, water supply, gas supply system, vehicle maintenance shop, etc can be seen everywhere. Especially in the process of industrial process control and technology measure, due to the flexibility of mechanical pressure gauge sensor has high mechanical strength and production is convenient wait for a characteristic, make the mechanical pressure gauge is widely used.

The working principle 

Pressure gauge by sensitive element within the table (bourdon tubes, bellows, bellows) of elastic deformation, again by the transformation mechanism of movement in table will pressure deformation to a pointer, pointer rotation to display the pressure.

 

The main structure

The overflow hole: if produce bourdon tube burst of emergencies, internal pressure to release through the overflow hole to the outside world, to prevent the glass panel burst. Note: in order to maintain the normal performance of the overflow hole, need to be at the back of the table to set aside at least 10 mm space, they cannot transform or overflow weir.Pointer: in addition to the standard pointer, other pointer is optional.Glass panel: in addition to the standard glass, other special glass, such as tempered glass, reflective glass is optional.Performance classification: regular (standard), steam with ordinary (M), heat resistant type (H), resistance to vibration mode (V) steam with vibration mode (MV) heat resistant to vibration mode (HV)Handling: banned oil/CAI in manufacturing water treatment to remove the residual in the liquid of water or oil.A specified: outside shell color in addition to the standard color, must be specified.Throttle valve (optional) : in order to reduce the fluctuating pressure, throttle valve is installed in the entrance pressure.

 

Use attention

1, the instrument must be installed vertically: 17 mm should be used when the wrench to tighten, should not be strong torsional case; Should avoid to touch when transportationHit:

2, instrument using appropriate in the ambient temperature of 25-55 ℃;

3, the use of the work environment vibration frequency < 25 hz, the amplitude is not more than 1 mm;12000一.

4, the use of Chinese environmental temperature is too high, indicating value of the instrument not back to zero or appear, indicating error can cut open upper case sealing rubber plug, make instrument lumen and atmosphere are interlinked

5, instrument using range, should be between the upper limit of 1/3 ~ 213;

6, in the measurement of corrosive medium, may the crystallization medium, the viscosity larger medium should add isolation device;Pressure gauge (figure 5)

7, instrument should be regular check (at least once every three months), if discover fault shall promptly repair;

8, instrument from the date of delivery, if half a year under normal storage conditions of use found failure or damage due to poor quality, by the company responsible for repair or exchange;

9, need measuring instrument of corrosive medium, should indicate the requirement when ordering.

 

Pressure gauge in almost all industrial processes and scientific research. In the heat pipe network, oil and gas transmission, water supply, gas supply system, vehicle maintenance shop, etc can be seen everywhere.Especially in the process of industrial process control and technology measure, due to the flexibility of mechanical pressure gauge sensor has high mechanical strength and production is convenient wait for a characteristic, make the mechanical pressure gauge is widely used.

 

Selection principle

1, the selection of type

Instrument type selection must meet the requirements of the process. Whether you need such as remote transmission, automatic recording, or the police; The nature of the measured medium (such as the temperature of the measured medium size, viscosity, corrosion, smudgy degree, whether the flammable and explosive, etc.) is put forward special requirements for instrument, on-site environmental conditions (such as humidity, temperature, magnetic field intensity, vibration, etc.) for instrument types of requirements, etc. Therefore correctly chosen instrument types according to the technical requirement is to guarantee the normal work of the instrument and the important premise of safety in production.Such as normal pressure gauge of the spring tubes with copper alloy using alloy steel (high voltage), and hydrogen pressure gauges spring tube materials are using carbon steel or stainless steel, are not allowed to use copper alloy. Because of ammonia and copper to produce chemical reaction, will explode, so general pressure gauges cannot be used for ammonia pressure measurement.Oxygen pressure gauge with normal pressure gauge in the aspect of structure and material can be exactly the same, just oxygen with oil pressure gauge must be forbidden. Because oil into oxygen system easy cause explosion. The oxygen pressure gauge used in calibration, not like ordinary pressure gauge using oil as working medium, and the oxygen pressure gauge to strictly avoid contact with oil in the store. If must use of existing oil pressure gauge to measure the oxygen pressure, must be cleaned with carbon tetrachloride repeatedly before use, carefully check until there is no oil.

2, the determination of measuring range

In order to keep the elastic component can work reliably within the scope of the safety of the elastic deformation, when selecting range, must according to the size of the measured pressure and the pressure change of speed, enough leeway, therefore, the upper limit of pressure gauge should be higher than the process in the production of possible maximum pressure value. According to "chemical control design technical regulations", the measurement stability, the maximum working pressure shall not exceed 2/3 of the upper limit value of the measurement; Measuring pulse pressure, the maximum working pressure shall not exceed the upper limit value of the measured 1/2; When measuring high pressure, the maximum working pressure shall not exceed 3/5 of the upper limit value of the measurement, generally measured pressure the most, a small value should be not less than 1/3 of the upper limit value of the instrument measurement, to ensure that the instrument of a linear relationship between output and input quantityAccording to the measured parameters of the maximum and the minimum calculated instrument on, after the floor, do not value directly as a instrument of measuring range. We when choosing instrument on the scale of limit, should be selected in the regulations of the state, the standard series. Pressure gauge measuring range of the standard series are: China - 0.1-0.06, 0.15:,1.6 0 and 1, 2.5, 4, 6, 10 x10 "MPa (where n is a natural integer can be positive and negative)

 

3, the level of accuracy

According to the process to allow maximum absolute error and the selected instrument most cheng, calculate the instruments allow maximum quoted by mistake, is poor, in the regulations of the state, the accuracy grade of determine the accuracy of the instrument. In general, chooses the precision instrument, measurement results are more accurate and reliable. But cannot think of, the higher the precision of instrument, the better, because the precision of the instrument in general, the more expensive, operation and maintenance, the more trouble.
