The working principle of electromagnetic relay is that when the electromagnet is energized, the armature is sucked down to make the two contacts, and the working circuit is closed. When the electromagnet loses its magnetism, the spring pulls the armature up, cutting off the working circuit. It is usually used in automatic control circuits. It is actually an automatic switch that uses a smaller current to control a larger current, so it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.

Linear rails, also known as linear guideways, are used for high-precision or high-speed linear reciprocating motion and can bear a certain torque. It enables high-precision linear motion under high loads. Linear guides are used to support and guide moving parts and perform reciprocating linear motion in a given direction. Like the high requirements of all precision parts, its selection needs to be considered from the following three aspects.

When the switch detects a utility power outage, it can start the generator, automatically transferring the load from the utility grid to the generator. Automatic transfer switches are used to automatically transfer loads from utility power to backup power or backup power in the event of a power outage or as required. A careful selection of switches ensures adequate capability, safety and maximum reliability in both normal and emergency situations. Therefore, factors such as load type, continuous current rating, voltage rating and style must be considered. In addition, price and compatibility must also be considered. In this article, we will introduce some points that you should consider when choosing automatic transfer switch.

An inverter, it has to be an inverter to be called that. It is directly different from the transformer, that is to say, the inverter can achieve DC input, and then output AC, the working principle is the same as the switching power supply, but the oscillation frequency is within a certain range, for example, this frequency is 50 Hz, the output is AC 50 Hz. An inverter is a device that changes its frequency. UPS inverter is a device that provides backup power to electronic equipment. It is mainly used to provide uninterrupted power supply to some equipment which requires high stability of power supply. In this article, we will introduce how to choose ups inverter.

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.

A centrifugal pump is a mechanical device designed to move fluid by transferring rotational energy from one or more driven rotors, called impellers. Fluid enters the rapidly rotating impeller along its axis and exits through the impeller's blade tips along its circumference by centrifugal force. The action of the impeller increases the velocity and pressure of the fluid and directs it towards the pump outlet. The pump casing is specially designed to compress the fluid from the pump inlet, direct it to the impeller, and then slow and control the fluid before discharging.
