    Brazed Plate Heat Exchanger in Refrigeration System

    The application of brazed plate heat exchangers in the refrigeration industry is very common. The brazed plate heat exchanger is an efficient and compact heat exchange equipment. In the 1880s, it was successfully developed as a continuous low-temperature sterilizer, and it began to be used in the food industry in the 1920s. Due to the uniqueness of the brazed plate heat exchanger in manufacturing and use, it is widely used in petroleum, chemical, light industry, electric power, metallurgy, machinery, energy and other industrial fields, thus becoming a very competitive variety in the heat exchanger family. In addition, brazed plate heat exchangers are also used in the refrigeration field. Let’s talk about its application and development below.

    What is a Industrial Endoscope Used For?

    The industrial endoscope is a new high-tech product designed and produced according to the inspection requirements of the inner surface of the pipeline in the petrochemical industry, industrial machinery, electronic and electrical industry, aerospace, etc. It integrates optical, mechanical, electrical, and image processing software.

The operator can use the high-resolution color CCD to freeze, enlarge, analyze, measure and print the report of the observed suspects and flaw detection parts with the help of a unique professional software processing system, thereby greatly improving the accuracy of judging the flaw detection parts on the inner wall of the pipeline.

    Industrial Water Chiller Applications

    Industrial water chiller is a kind of water cooling equipment that can provide constant temperature, constant current and constant pressure. The principle of the chiller is to inject a certain amount of water into the internal water tank of the machine, and the water is cooled by the refrigeration system. Afterwards, the water pump inside the chiller injects cryogenically frozen water into the equipment that needs to be cooled. The chilled water takes away the heat inside the machine and returns the high-temperature hot water to the water tank for cooling. In this way, the circulation exchange cooling can achieve the function of cooling the equipment.

    Safe Use of Clamp Meter

    Clamp meter is the abbreviation of clamp ammeter. It is a portable measuring instrument that can directly measure the AC current of the circuit without disconnecting the circuit. It is called a clamp ammeter because of its shape with a movable opening in the shape of a clamp. Common clamp meters do not have the ability to measure AC and DC voltages of 1kV or above. It is recommended not to measure parameters higher than this voltage to avoid personal electric shock.

    Function of Pipette in Laboratory

    The pipette is a single-channel micropipette that is commonly used in biological and chemical laboratories to move liquids with a small volume, and it is a measuring tool for transferring liquid from the original container to another container within a certain range. The design of the pipette fully conforms to the ergonomic principle, and is characterized by easy disassemble and maintenance. The pipette has five modes: Pipetting mode, sample mixing mode, reverse aspiration mode, electrophoresis sampling mode, and graded pipetting mode. The pipette can be applied to liquids such as high viscosity liquids, high vapor pressure liquids, and foaming liquids. Pipettes are widely used in clinical diagnostic laboratories, biotechnology laboratories, pharmaceutical and chemical laboratories, environmental laboratories, and food laboratories.

    How does Water Quality Tester Measure Turbidity?

    Turbidity is one of the most important parameters when using water quality tester to measure the water quality of the natural environment. However, many people do not fully understand the details of turbidity measurement. Here is how does water quality tester measure turbidity.

    The water quality in the natural environment is easily affected by some suspended particulate matter, and these suspended particulate matter can be measured by a water quality tester to get a specific value, that is, turbidity. In general, turbidity is closely related to climate or surface water conditions, so if you want to know whether the environmental conditions of lakes and rivers have changed, you can judge by measuring the turbidity of the water.

    Dehumidifier for Basement

    The basement is a common but special site. Nowadays, the utilization rate of the basement is increasing year by year. At the same time, it is a special site. Because it is lower than the ground, hidden in the ground, the room temperature is low, and the ventilation is not very good. Therefore, the humidity in the basement is generally higher than the ground, and some even have excessive humidity, which seriously affects various production and life activities in the basement. Therefore, we urgently need to deploy a dehumidifier in the basement for dehumidification. Today, we will briefly discuss how to appropriately use the dehumidifier in the basement. It is recommended that the corresponding model can be selected according to the different functions of the basement.

    Surge Protection Device for Low Voltage Power System

    The lightning stroke discharging between the cloud layer and earth is constituted by one or several individual lightning. Every lightning carries several currents with very high amplitudes and short duration. One typical lightning discharging shall include two or three lightning. There is about an interval of 1/20 second between two lightnings. Most lightning currents drop in the scope of 10, 000~100, 000 Amp, and its duration is generally lower than 100ms.
    Because of the operation of high-capacity equipment and frequency conversion equipment in the power supply system, an increasingly serious interior surge problems have been generated. We conclude it into the influence of transient overvoltage (TVS). Any power equipment has the allowed scope of power supply voltage. Sometimes, even very narrow overvoltage impact might damage the equipment power supply or entire equipment. The destructive effect of transient overvoltage (TVS) is just like this. In particularly, as to some sensitive microelectronics devices, some very low surge impacts will probably case fatal damage.

    pH Meter for Wastewater Treatment

    In primary treatment, the suspended solid pollutants in the sewage will be removed, and most physical treatments can only meet the requirements of primary treatment. After the primary treatment, 30% BOD can be removed from the wastewater. It doesn’t meet the emission standard. Primary treatment is a pre treatment of secondary treatment.
    In secondary treatment, colloid and dissolved organic pollutants (BOD, COD) in the waste water will be removed, and the removal rate can be higher than 90%. The organic pollutants meet emission standards. Use pH meter to monitor whether the emissions of organic pollutants are up to standard.
    In tertiary treatment, non biodegradable organic pollutants, N, P and other soluble inorganic substances that lead to eutrophication of water bodies are further processed. Main methods are biological nitrogen and phosphorus removal method, coagulant sedimentation method, sand filtration method and activated carbon adsorption method.

So it’s necessary to record the temperature and humidity of the archives, prevent the occurrence of malignant accidents. Application of temperature and humidity sensors simplifies the temperature and humidity record, saves the cost of cultural relics preservation and makes the work more scientific, prevents it from being disturbed by too much human factors.

    How to Calibrate Digital Panel Meter

    When a new system is used for the first time or the meter, sensor is replaced, calibration must be made before use.
    There are two kinds of calibration in general, one is the physical calibration (in this mode, two points needs to be calibrated, namely the zero position and the range), and another is the digital calibration.

    Physical calibration is applicable for most weighing systems, and digital calibration is used in the fields when the physical demarcation can't be used. However, digital calibration can't eliminate the errors, its accuracy is related with the sensor’s sensitivity, range and wiring system (four-wire or six-wire), the division value or maximum range setting, as well as the signal loss on the junction box and cable.
    The scale division and maximum range shall be set before calibration.
    Before calibration, the instrument shall be powered on for at least 15 minutes until the sensors and meters reach the thermal equilibrium state.
