Corrugated compensators are also called expansion joints and expansion joints, mainly to ensure the safe operation of pipelines. The English name is expansion joints, Bellow Expansion Joint, which is a flexible, thin-walled, transversely corrugated device with expansion function, which is composed of metal bellows and components. The working principle of the bellows compensator is mainly […]

From the perspective of energy conversion, hydraulic pumps and hydraulic motors are hydraulic components that work reversibly. Inputting working fluid to any hydraulic pump can turn it into a hydraulic motor working condition; on the contrary, when the main shaft of the hydraulic motor is external When the torque is driven to rotate, it can […]

1. What is a wavelength division multiplexer WDM (Wavelength Division Multiplexing) combines two or more optical carrier signals of different wavelengths (carrying various information) at the transmitting end through a multiplexer (also known as a multiplexer), and The technology of transmitting in the same optical fiber coupled to the optical line; at the receiving end, […]

1. The composition of the integrated operational amplifier The integrated operational amplifier circuit can be divided into four basic components: input stage, intermediate stage, output stage and bias circuit. The input stage is a key part to improve the quality of the operational amplifier, which requires high input resistance, which can reduce the zero drift […]

Two conductors close to each other, with a non-conductive insulating medium in between, constitute a capacitor. When a voltage is applied between the two plates of a capacitor, the capacitor will store charge. The capacitance of a capacitor is numerically equal to the ratio of the amount of charge on one conductive plate to the […]

The topological principles of DC Circuit breakers are complex and diverse. According to the different key breaking devices in DC circuit breakers, DC circuit breakers can be divided into three categories: mechanical DC circuit breakers, all solid state DC circuit breakers, and a combination of mechanical switches and solid state switches. Hybrid DC circuit breaker. […]

A DC contactor refers to a contactor whose iron core is DC controlled, and its load can be either DC or AC. The iron core of the DC contactor is different from the AC contactor. It has no eddy current, so it is generally made of mild steel or industrial pure iron in a round […]

The so-called high frequency refers to the frequency of the alternating current of 50 Hz, and generally refers to the high frequency current of 50KHz to 400KHz. When high-frequency current passes through a metal conductor, two peculiar effects are produced: skin effect and proximity effect. High-frequency welding uses these two effects to weld steel pipes. […]

1. What is a thin client The thin client is a small-scale industry-specific commercial PC designed based on the PC industry standard that uses a professional embedded processor, a small local DOM Electronic disk, and a streamlined operating system. The configuration includes a professional embedded processor with low power consumption and high computing functions. Non-removable […]

1. What is a turbine governor Electricity is one of the important energy sources used in my country’s industrial production and daily life applications. With the ever-decreasing non-renewable resources in my country, the superiority of hydropower is increasingly shown. As an important equipment of a hydropower plant, the governor of a hydroturbine plays a key […]
