Vacuum circuit breakers are used for switching purposes in high voltage (HV) applications. Vacuum circuit breakers are more efficient, smaller and less expensive. VCB breakers have a much longer lifespan than conventional circuit breakers and require little maintenance. VCB (Vacuum circuit breakers) are ideal for typical utility and industrial applications.

UPS, also known as an uninterruptible power supply, is a constant voltage and constant frequency uninterruptible power supply with the energy storage device and inverter as the main component. It mainly provides uninterrupted power supply to a single computer, computer network system or other power electronic equipment. When the mains input is normal, the UPS will stabilize the mains and supply it to the load. At this time, the UPS is an AC mains voltage stabilizer, and it also charges the battery inside the machine. When the mains power is interrupted (accidental power failure), the UPS will immediately supply the 220V AC power to the load by inverting the power of the battery in the machine, so that the load can maintain normal operation and protect the software and hardware of the load from damage.

An induction motor is similar to a poly-phase transformer whose secondary is short circuited. Thus, at normal supply voltage, like in transformers, the initial current taken by the primary is very large for a short while. Unlike in DC motors, large current at starting is due to the absence of back emf. If an induction motor is directly switched on from the supply, it takes 5 to 7 times its full load current and develops a torque which is only 1.5 to 2.5 times the full load torque. This large starting current produces a large voltage drop in the line, which may affect the operation of other devices connected to the same line. Hence, it is not advisable to start induction motors of higher ratings (generally above 25kW) directly from the mains supply.

A screw feeder is a mechanism that uses a rotating screw blade, usually inside a tube, to move liquid or granular materials. They are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or slightly inclined as an efficient way to convey semi-solid materials including food waste, wood chips, aggregates, grains, animal feed, boiler ash, meat and bone meal, municipal solid waste, and Many others. Screw conveyors can move material horizontally inclined or vertically. They are used for feeding, dispensing, collecting or mixing, and can be equipped with heating or cooling when transferring using appropriate covers and gaskets, they are easily dust or weatherproof and rodent proof.

A rotary switch is a switch operated by rotation. These are often chosen when more than 2 positions are needed. A rotary switch consists of a spindle or "rotor" that has a contact arm or "spoke" which projects from its surface like a cam. It has an array of terminals, arranged in a circle around the rotor, each of which serves as a contact for the "spoke" through which any one of a number of different electrical circuits can be connected to the rotor. The switch is layered to allow the use of multiple poles; each layer is equivalent to one pole. Alternatively the rotation can be limited to a fraction (half; third etc.) of a circle and then each layer can have multiple (two; three etc.) poles.

Today we will introduce what is a voltage sensor and its working principle and function. We hope that after reading this article, you will have a clearer understanding of voltage sensors.

A voltage sensor is a sensor that senses the voltage being measured and converts it into a usable output signal. In various automatic detection and control systems, voltage sensors, often need to track and collect high-speed changing AC and DC voltage signals.

How long can UPS equipment supply power? UPS manufacturers have industrial UPS power supplies with 10 minutes, 30 minutes and other types. Is the UPS time longer the better? In fact, it is better to control the UPS time within 8 hours. Why is this?

A sensor is a detection device. The sensor can sense the measured information, and can transform the sensed information into electrical signals or output other required information forms according to certain rules. In this way, sensors meet the requirements of information transmission, processing, storage, display, recording and control.

The characteristics of the sensor include: miniaturization, digitization, intelligence, multi-function, systematization and networking. It is the first part to realize automatic detection and automatic control. The existence and development of sensors allow objects to have senses such as touch, taste, and smell, and make objects slowly become alive.

A vacuum cleaner is a device that causes suction in order to remove dirt from floors and other surfaces. The dirt is collected by either a dust bag or a cyclone for later disposal. We've heard of workers on the factory floor dying of pneumoconiosis, and this is a reality. The harsh production workshop environment has done great harm to people's health. As events revealed, improving the environment of production workshop area has become an important task of enterprise. Industrial vacuum cleaners can handle several hundred litres of dust. However, it will generate huge noise in use. This article will introduce several methods to reduce the noise of industrial vacuum cleaner.

A PLC takes in inputs, whether from automated data capture points or from human input points such as switches or buttons. Based on its programming, the PLC then decides whether or not to change the output. A PLC's outputs can control a huge variety of equipment, including motors, solenoid valves, lights, switchgear, safety shut-offs and many others.

A load cell, also known as a load or force transducer, is a sensor that measures applied forces. Load cells are capable of measuring both tension (force required to pull something) and compression (force required to push something). In order to measure these forces, the sensor creates an electrical output that changes depending on the amount of resistance being applied.

Programmable relay stores some typical relay logic control program in internal memory in advance and realize some simple logic control and sequence control function by the user program combination and calls. The user program uses the ladder diagram or functional diagram language through panel, intuitive and easy to understand. The switching signal input by the button, switch etc.

A load cell is a force transducer. It converts a force such as tension, compression, pressure, or torque into an electrical signal that can be measured and standardized. As the force applied to the load cell increases, the electrical signal changes proportionally. We covered How to use PLC to monitor the data of load cell transmitter in our previous blog. Today we'll show you how to use HMI to display the data of load cell in real time.

A load cell is a force transducer. It converts a force such as tension, compression, pressure, or torque into an electrical signal that can be measured and standardized. As the force applied to the load cell increases, the electrical signal changes proportionally. The most common types of load cell used are strain gauges, pneumatic, and hydraulic.

In the automated production process of industries such as food and beverages, daily chemicals, medicine, semiconductors, etc., in order to ensure the consistency of product quality, the era of direct manual monitoring and intervention in the production process has gone. Liquid level measurement and monitoring are playing an increasingly important role. It can be said that the measurement and monitoring of the liquid level directly affects the quality of the product, and even whether the production process can be carried out smoothly.

A three phase converter is needed when the "phase" required does not match the "phase" available. In other words, the equipment needs three phase power and only single phase power is available. Phase converters operate by converting single phase power into three phase power. They can also provide split phase voltages from the three phase power source. A three phase converter is used to allow operation of three phase equipment when single phase electrical services are the only power available or vice versa. The majority of the time phase converters are utilized to produce three phase power from single phase power sources as utility companies will associate higher fees for three phase electrical services due to the extra transformers, cabling, and metering required. In this article, we will introduce how to convert single phase to three phase converter.

The working principle of the constant pressure water pump is as follows:

1. The VFD drives the water pump, and the pressure sensor/transmitter feeds back the pressure signal to the VFD to form a closed loop system.
2. When the water pipe pressure is less than the set value, the VFD wakes up and starts pumping water.
3. When the pressure does not reach the set target, the operating frequency will continue to increase to the rated frequency of the pump.
4. When the pressure is greater than the set pressure, the operating frequency will decrease.
5. When the pressure is greater than the sleep pressure, the frequency decreases to the sleep frequency for a period of time, and then stops pumping water.
6. When the pressure is lower than the wake-up pressure, the pump starts to run again.

We all know vertical centrifugal pumps and horizontal centrifugal pumps, both of which are centrifugal pumps. It can be used in everyone's daily life. So what is the difference between these two pumps? And what are the differences?
