Main components of stainless steel pressure gauge

The stainless steel pressure gauge can be seen from the outside first, and then its internal structure, including the role of devices and its devices will lead to those failures, so that we can find the root of the problem as soon as possible when the failure occurs and reduce the losses caused by the failure. The external structure mainly includes case, watch glass, pointer and liquid receiving device. If there is leakage, you can check whether the case is damaged, whether the liquid receiving material leaks, and then check the sealing ring. General leakage is caused by these positions. However, the index is not accurate enough. It is possible to check whether the pointer is bent or deformed. There are also welds made of liquid-contacting materials to be inspected, and that position is also prone to leakage.

The internal structure is mainly composed of the movement and elastic elements. If the pointer can't return to zero and the measured value is inaccurate, it is mostly caused by the elastic elements, because long-term overpressure measurement may lead to the deformation of the elastic elements, which will make the pointer unable to return to zero and the indicated value inaccurate. However, when we use the booster and the pointer does not respond or stays at zero, then this may be caused by the damage of the movement.

Main problems of diaphragm pressure gauge and their causes

Please don't panic when your diaphragm pressure gauge doesn't work normally, or just stops heating your house completely. It may not be the fault of the diaphragm pressure gauge itself, but other reasons may cause the diaphragm pressure gauge to fail to work.

Problem: The diaphragm pressure gauge is not heated.

Cause: thermostat-this is usually the embarrassing cause of the failure of diaphragm pressure gauge. The customer will only ask the service staff to have the technician check the thermostat and confirm that it is set incorrectly. Make sure that it is switched to "heating", the required temperature is higher than the existing room temperature, and the fan is set to "automatic". If you have a programmable thermostat, you may need to override the settings to verify whether the thermostat is causing the problem or not.

As soon as the circuit breaker is checked. It may trip or blow, which will cause the diaphragm pressure gauge to fail to open.

Faulty indicator light-this is a major problem, and you may feel very depressed when you don't know why it happened. The indicator light may go out for a variety of reasons. This may be caused by dirty trachea or even ventilation. If you suspect that there is something wrong with the indicator light, please contact a professional to help diagnose and repair the problem.

No natural gas or propane flows. This sometimes happens when the air pressure regulator fails and the air supply is turned off or only the valve is closed. If you doubt one of the above two situations, please don't try to solve it yourself. It is safe to give it to a trained professional.

Problem: Insufficient calories.

Reason: Dirty air filter-Dirty diaphragm pressure gauge filter is blocked by dust, pet hair and other debris, which will prevent air from flowing through the heat exchanger and make it more difficult to warm your house. Please make sure to replace the air filter every one to three months, depending on the variety.

Unbalanced airflow-If you run the diaphragm pressure gauge for a long time and at a high temperature, it doesn't matter. Some rooms never seem to get warm enough. It may be airflow. In this case, it is not a diaphragm pressure gauge at all. In order to determine whether this is a problem, you should conduct a comprehensive airflow analysis, correction and balance.

Leaky pipes-cracks in pipes, broken seals and even poor insulation will make warm air escape, which makes it very difficult to keep your house warm. If you suspect that this is a problem, please consider professional inspection, sealing or insulation of the pipeline.

Problem: high electricity bill

Reason: lack of maintenance-among all the problems of diaphragm pressure gauge, the lack of maintenance of diaphragm pressure gauge is the chief culprit of Z. In terms of efficiency, a well-maintained diaphragm pressure gauge will always be better than its dirty and untimely diaphragm pressure gauge. You should plan to professionally clean and maintain the diaphragm pressure gauge at least once a year to improve efficiency and performance. An efficient diaphragm pressure gauge consumes less energy. When you use less energy, your expenses will be reduced.

Go beyond one's first condition-efficiency. Today's diaphragm pressure gauge is more efficient than yesterday's old diaphragm pressure gauge. If your equipment is over 15 years old, you should consider buying a new diaphragm pressure gauge. In the long run, the cost savings will exceed the cost of upgrading.

Seven Precautionary Measures for Installation of Stainless Steel Seismic Gauge

The shell and internal original parts of the stainless steel earthquake-resistant gauge are made of stainless steel, and silicone oil is filled in the gauge body, so that the pointer of the pressure gauge plays a role in shock absorption and earthquake resistance. The stainless steel shock-resistant gauge has both the shock-resistant performance and the corrosion-resistant performance of the stainless steel pressure gauge. The stainless steel shock-resistant pressure gauge is suitable for occasions where the vibration of industrial and mining sites is large and the measured medium is corrosive.

1. The operating environment temperature of the instrument is -40~70℃, and the relative humidity is not more than 80%. If it deviates from the normal operating temperature of 205℃, it shall be included in the additional temperature error.

2. The instrument must be installed vertically, and strive to keep the same level with the measuring point. If the difference is too high, it is included in the additional error caused by the liquid column, so it is unnecessary to consider when measuring gas. When installing, block the explosion-proof port at the back of the case to avoid affecting the explosion-proof performance.

3. The measuring range of the instrument in normal use: it shall not exceed 3/4 of the upper measuring limit under static pressure and 2/3 of the upper measuring limit under fluctuation. Under the above two pressure conditions, the measurement of large pressure gauge should not be less than 1/3 of the lower limit, and the vacuum part should be used completely when measuring vacuum.

4. In case of instrument pointer failure, loose internal parts, failure to work normally, etc., it should be overhauled, or the manufacturer should be contacted for maintenance.

5, the instrument should avoid vibration and collision, so as to avoid damage.

6. Please indicate the model and name of the instrument when ordering; Measuring range of the instrument; The accuracy grade of the instrument deviates from the requirements of positive packaging and others.

7. The stainless steel shock-resistant pressure gauge is not suitable for the environment with strong oxidants such as oxygen, chlorine, nitric acid and hydrogen peroxide.
