Explosion-proof motor Explosion-proof motor is a kind of motor that can be used in flammable and explosive factories, and does not generate electric sparks during operation. Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, it is also widely used in textile, metallurgy, city gas, transportation, grain and oil processing, papermaking, medicine and other departments. As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors and other transmission machinery.

The dosing pump is a special positive displacement pump that can meter the delivered fluid. It is generally composed of a control part, a driving part, a transmission part and an overcurrent part. The main difference between an electromagnetic diaphragm metering pump and other metering pumps is the driving part. The rated flow of the ATO dosing pump is in the range of 1.08-31.2 L/h, and the output pressure is 1.8-22.7 bar. The outlet flow of the dosing pump can be realized according to the stroke frequency.

A pressure sensor is a device or instrument which is able to measure the pressure in gases or liquids. A pressure sensor consists of a pressure-sensitive element which can determine the pressure being applied and components to convert the information into an output signal. Before using pressure sensors for measurement work, we need to perform detailed calibration work on them, because if we do not calibrate them before use, various faults or inaccurate measurement results may occur during the measurement process.

Explosion-proof motor is a type of motor with explosion-proof performance. It is a kind of motor that can be used in flammable and explosive places, and it does not produce electric sparks during operation. It has a structure different from that used in ordinary environments. It can prevent the combustible gas and dust outside the motor from entering the motor to the greatest extent, or even if it enters, explosion-proof motor will not ignite the combustible gas and dust in the surrounding environment from the flame out of the casing when short-circuited and caught in the interior.

The advantages of brushless motors are high speed, high efficiency, and low maintenance costs. Brushless motors are widely used in computers, handheld power tools, and various vehicles. In modern industry, people generally choose to purchase brushless motors. Brushless motors are divided into brushless outrunner motors and inrunner motors. Next, the differences between the two types of motors will be following.

Pressure sensors are one of the most commonly used sensors in industrial practice and are widely used in a variety of industrial automation environments and many other industries. When purchasing a pressure sensor, the stability of the product is a major consideration. What are the factors that affect the stability of pressure sensors? Next, we will detail the factors that affect the stability of pressure sensors.

Accelerometer sensors are ICs that measure acceleration, which is the change in speed (velocity) per unit time. Measuring acceleration makes it possible to obtain information such as object inclination and vibration. It is usually composed of mass blocks, dampers, elastic elements, sensitive elements and adaptive circuits. During the acceleration process of the sensor, the acceleration value is obtained by using Newton's second law by measuring the inertial force on the mass block.

An automatic transfer switch (ATS) is a device that automatically transfers a power supply from its primary source to a backup source when it senses a failure or outage in the primary source. The auto transfer switch has advantages of simple structure, easy & reliable operation, no noise, small impact, and long service life. Auto changeover switch is suitable for the illuminating circuits of commercial buildings, shopping mall, banks, and high-rise buildings where the power supply can not be cut off for a long time.

A switch is an essential component of a UPS system that converts the system to a stable power source in the event that the current power source is turned off. This can be done with one of two different options. One is an automatic transfer switch and the other is a static transfer switch. Depending on how they work, they are ideal for two different purposes. Choosing the right switch for the job ensures your business is always on.

Thanks to the rapid development of technology nowadays, there are various kinds of isolation switches on the market, designed for different uses. They may be intended specifically for industrial applications or for home use. Choice of isolator switches depends on the requirement and application. We'll take a look at them one at a time and try to understand what's special about them. In this article, we will talk about types and applications of isolator.

Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from which it exits. Common uses include water, sewage, agriculture, petroleum, and petrochemical pumping. 

A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers. Fluid enters the rapidly rotating impeller along its axis and is cast out by centrifugal force along its circumference through the impeller's vane tips.

We are interested in knowing how to disassemble the water-cooled spindle of a CNC engraving machine to clean waterway impurities. In fact, the correct approach is not to disassemble the water-cooled spindle for cleaning, because the structure of the water-cooled spindle is quite complex, non-professionals to disassemble easy to damage the spindle, affecting the concentricity of the spindle components and parts of the connection assembly, must be disassembled to clean up, should be handed over to the manufacturer to carry out.

The spindle motor is a high speed, high precision mechanical and electrical precision component, we have a variety of failure phenomena in the maintenance of spindle motor process, ATO summarized in the maintenance of spindle motor common failures and what are the solutions?

An autotransformer is a special transformer with primary and secondary without insulation. In short, it means that its primary and secondary windings are on the same winding, i.e., a transformer with only one winding, which means it is a special transformer with a common set of coils for output and input. When the autotransformer is used as a step-down transformer, part of the line turns are taken out from the winding as the secondary winding, and when the autotransformer is used as a step-up transformer, the applied voltage is only added to part of the line turns of the winding. Because DC power cannot be directly stepped up, it needs to go through electronic and other components.

For the generator working in order, maintenance at fixed period is very important. The diesel generator is consisted of a diesel engine, alternator, control panel, frame, etc. Please read the relative manual for the maintenance.

Before maintaining the generator, stop the engine. The surrounding condition of the generator is of better ventilation because engine exgaust includes harmful CO. After stopping the generator, clean it immediately to prevent corrosion and remove the sediment.

Before operating the diesel generator, please read the manual. Especially following points should be paid attention to for preventing the accident happened. The engine fuel is light diesel. It is forbidden to adopt gasoline and kerosene etc. When the oil overflows, please use a clean cloth to remove the oil. It is not permitted to have diesel generators with gasoline, kerosene, match and inflammable material, because the temperature around the muffler is very high when the engine is operated. For the sake of better ventilation during the generator operation, the distance between the diesel generator and the building should be more than 1.5meters. The diesel generator should be operated on plain ground. Otherwise, the oil will overflow from a diesel generator.
