Problems that may occur during the use of boiler level gauges

       The boiler level gauge has the function of accurate continuous measurement and control of the liquid level under all operating conditions, and can automatically compensate for changes in the liquid medium, dielectric constant change, vapor medium, and dielectric constant. Key adjustment, easy calibration, with self-diagnosis, full temperature range, measurement system, temperature drift no more than 0.1PF, electrode using non-metallic materials, mechanical and electrical integration. The intelligent boiler drum liquid level gauge has the advantages of high temperature resistance, high pressure, long life, high reliability, high precision, and high stability. It can be widely used in various specifications of industrial steam drums, high-increasing, low-adding, reformer and other pressure vessels. Bit monitoring.

       The importance of boiler level gauge water level measurement is well known. However, there are many unrecoverable defects in the balanced container type (differential pressure) measurement method used for continuous measurement of boiler drum water level, which is mainly reflected in the following several aspects:

1. It is not possible to carry out full working condition measurement, there is a “false water level” measurement, and it takes a long time to establish a stable differential pressure condition under unstable operating conditions such as boiler start, stop, emptying, continuous row, accident, etc., or a long recovery time. It is impossible to establish normal differential pressure and require manual intervention.

2. Under the stable operating conditions, due to structural constraints, the compensation for system measurement errors caused by the temperature at the water side cannot be completely resolved. Under the conditions of accidents such as boiler shortage and full water, excessive system measurement error may bring serious consequences.

3. The structure is complex, there are many static seal points, the construction scale is large and there is a problem of winter insulation.

4, the measurement time lag is long, can not immediately respond to changes in the boiler water level, measurement signal quality is poor.

5, due to the existence of condensation tube heat, the use of high cost.

These defects are due to the differential pressure measurement principle and its unreasonable sampling structure, and cannot be improved. Under normal operating conditions, it has caused great dangers for the safe operation of boilers.

The company's boiler level gauge uses a unique structure, high temperature, high pressure, in which the transmitter uses the relationship between the change of the liquid level and the change in the capacitance of the measuring probe, through the special mode system software will change the detected capacitance After the compensation calculation, the 4-20mADC standard signal, which is proportional to the material level, is output. With high precision, high stability, high temperature, high pressure, long life characteristics.

Duplex Filters

Describe:

 Duplex filters, also called double-barrel return pipeline filters, are composed of two single-barrel filters and two six-way reversing valves, which have simple structure, easy to use, and with by-pass valve and filter core pollution clogging transmitter, in order to ensure the safety of the system.

Characteristics:

The double-barrel filter is mainly installed on the return pipeline of the hydraulic system. Various kinds of dirt such as abrasive particles produced by various hydraulic components in the working process can be intercepted by setting the Oil Filter of the return pipeline to avoid returning to the fuel tank again. Inhaled again by a hydraulic pump. The allowable pressure difference of the oil filter in the return pipeline is 0.3 ~ 0.5mpa. according to the different pressure level. The accuracy is determined according to the oil contamination requirement. In the working process, when the filter core is clogged to a certain extent and the filter core needs to be cleaned or replaced, it is necessary to stop the mainframe operation to replace the filter element, which is not only a waste of time but also can not meet the needs of continuous operation of the main engine. The double-barrel filter can effectively solve the defect of single-barrel filter and can clean or replace the filter core without stopping to ensure the mainframe work normally and continuously. When one filter core is blocked and needs to be replaced, it is not necessary to stop the mainframe operation. Just open the pressure balance valve and turn on the reversing valve. The other filter can take part in the operation and then replace the blocked filter element

Applications:

1. Metallurgy: used for filtration of rolling mill, continuous casting machine hydraulic system and various lubricating equipment.

2. Petrochemical: separation and recovery of products and intermediate products in refining and chemical production, filtration of oil well water and natural gas.

3. Textile: purification and uniform filtration of polyester melt during drawing, protection and filtration of air compressor, deoiling and dewatering of compressed gas.

4. electronics and pharmacy: reverse osmosis water, deionized water pre-treatment filtration, washing liquid and glucose pretreatment filtration.

5. Thermal power and nuclear power: gas turbine, boiler lubrication system, speed control system, bypass control system oil purification, feed water pump, fan and dust removal system purification.

6. Processing equipment: paper machinery, mining machinery, injection molding machine and large precision machinery lubrication system and compressed air purification, tobacco processing equipment and spraying equipment filtering.
