    Troubleshooting Combustible Gas Detector

    When using the fixed combustible gas detector, it is inevitable that there will be some failures. Then, why do these failures occur, and how can we troubleshoot them? The following are simple examples of several troubleshooting methods.
    In the process of using the combustible gas detector, it should not be installed close to the air conditioner and heating equipment. If the cold or warm air directly flows to the gas detector, it may cause the change of electrical resistivity of the alarm platinum wire and then the error occurs. Therefore, the alarm should be located far away from air conditioners and heating equipment to avoid the gas detector failures caused by improper placement.

    What is a Gas Detector?

    AG亚洲Gas detector is an instrument for detecting the concentration of gas leakage, including portable gas detector, hand-held gas detector, fixed gas detector, online gas detector, etc. It mainly uses a gas sensor to detect the types of gases present in the environment, and the gas sensor is a sensor used to detect the composition and content of the gas.

    Gas Detector, Gas Leak Detector

    A gas detector is an instrument used for the gas leakage concentration detection. The gas detector works mainly by using gas sensor inside to detect the presence of gas in the environment. The gas sensor serves as a reference point or scale which is the core part of gas leak detectors. Different gas sensors can react to different gases, so that the gas detector can detect different types and concentrations of gases. When the detected gas concentration exceeds the preset value, the alarm will sound to warm the user. So, it is an essential part of safety system to safe guard your life.

    How does Water Quality Tester Measure Turbidity?

    AG亚洲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.

    Laser Marking Machine Troubleshooting

    When a fault occurs during the use of the laser marking machine, the problem should be solved in time, otherwise it will directly affect the workshop output. Actually, the maintenance of the laser marking machine is a little troublesome, but the working principle is very simple, so many problems can be solved by the operator without professional technicians. Here are several common problems and causes of laser marking machine.

    How to Use Rotational Viscometer?

    Rotary viscometer is widely used to measure the dynamic viscosity of various fluids such as grease, paint, coating, plastic, food, medicine, adhesive and so on. It is popular because of the simple structure, cheap price, convenience and practicality. But in the process of communicating with customers, it was found that many of them have some doubts about how to use the rotational viscometer correctly. Now ATO will tell you the correct use of rotational viscometer, so that you can use ATO’s rotational viscometer more efficiently and conveniently.

    What are the Different Types of Viscometer?

    Viscometer is an instrument used to measure the viscosity of a fluid ( liquid or gas ). Viscosity is the physical quantity of internal friction occurring in the fluid when the fluid is flowing. It is the ability of the fluid to resist deformation and an important index used to identify some finished or semi-finished products. Viscosity varies with the type and temperature of the fluid. And what are the different types of viscometer? The following are seven common types which are widely used in petrochemical, pharmaceutical, food, light industry, textiles and other fields.

    Troubleshooting Rotary Vane Vacuum Pump

    The installed rotor of a rotary vane vacuum pump is tangent to the stator fixed surface inside the pump eccentric, two or more rotary vanes slide in the rotor slot and contact with the inner wall of the stator, which makes the pump chamber divided into several variable volumes.

    Generally, the clearance between the rotary vane and pump chamber is sealed by oil, so the rotary vane vacuum pump is usually an oil seal mechanical vacuum pump.

    AG亚洲The rotary vane vacuum pump can remove the dry gas from the sealed container. It can remove a certain amount of condensable gas if it has gas ballast device. However, it is not appropriate to remove some gases that are highly oxygenated, corrosive to metals, react chemically to pump oil, and contain particulate dust.

    The rotary vane vacuum pump failure is divided into operation failure and performance failure.

    Water Chiller Troubleshooting

    The water chiller is a water cooling equipment, which can provide constant temperature, constant current and constant pressure. The principle of the water chiller is that a certain amount of water is injected into internal water tank, making refrigerating system cools the water, and then water pump inside the machine injects cryogenic freezing water into an equipment which needs to cool back. The frozen water takes away calories inside the machine, then high temperature water backflow in water tank cools down. Cycle alternation cool reaches a function that cools equipment.

    How to Wire & Install Isolation Transformer

    The "input" and "output" terminals of a isolation transformer should be short-circuited to test their insulation resistance against the ground wire by a megohmmeter. When measuring by 1000V megohmmeter, the resistance value is greater than 2M ohms. The cross-sectional area of the isolation transformer input and output power lines should meet the requirements of its current value. It is appropriate to configure the electric current density of 2 ~ 2.5a /mm2.

    Direct Drive Air Compressor vs. Belt Driven Air Compressor

    As an important form of energy generation, air compressors are widely used in various industrial fields, including mechanical, metallurgy, Electronic power, medicine, packaging, chemicals, food, textile, transportation and so on.
    Direct drive of air compressor refers to the motor main shaft to drive the rotor by the coupling and the gearbox speed, which is not actually a direct drive in practical sense.
    Direct drive in the true sense means that the motor is directly connected with the rotor (Coaxial), which has the same speed. This situation is obviously very rare. Therefore, it is a wrong view that there is no energy loss in direct drive.
    Another drive way is belt driven, which allows the rotating speed of the rotor to be changed by pulleys of different diameters.
