Shaft couplings are also called shaft couplings. A mechanical component used to firmly connect the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque. Sometimes it is also used to connect shafts and other parts (such as gears, pulleys, etc.). It is often composed of two halves, which are respectively connected by keys or tight fittings, and are fastened at the ends of the two shafts, and then the two halves are connected in some way. The shaft coupling can also compensate for the offset (including axial offset, radial offset, angular offset or comprehensive offset) between the two shafts due to inaccurate manufacturing and installation, deformation during operation or thermal expansion, etc. and shock mitigation and vibration absorption.

A piston air motor is an air motor that converts the linear motion of several pistons into rotary motion through a crank or a swash plate. According to their different structures, they can be divided into radial piston type and axial piston type. Piston air motors are suitable for applications with low speed and high torque. The air consumption is not small, which has many components, and the price is expensive. Piston-type air motors are mainly used in mining machinery, and can also be used as drive motors for conveyor belts, etc.

The flexible diaphragm coupling is composed of several groups of diaphragms (stainless steel thin plates) connected with the two halves of the coupling by bolts alternately. Each group of diaphragms is formed by stacking several pieces. The relative displacement of the two shafts is a high-performance metal elastic element flexible coupling.
Three-phase unbalance is an important indicator of power quality. Although there are many factors affecting the power system, most of the normal unbalance is due to three-phase components, line parameters or load asymmetry. Because the factor of three-phase load is not certain, the three-phase voltage and current of the power supply point are prone to unbalance and line loss. Furthermore, it will adversely affect the motor on the power supply point and endanger the normal operation of the motor. Therefore, if the three-phase unbalance exceeds the range that the distribution network can bear, the safe operation of the overall power system will be affected. There are many reasons for three-phase voltage imbalance, such as single-phase grounding, disconnection resonance, etc. The operator should correctly distinguish the reasons and deal with them quickly.
A light may come on when the machine is running, or flash when the machine is experiencing technical problems. Lights on the elevator will light up to indicate which floor the elevator is on and when it is safe to leave the elevator. These are just two of the many applications for LED indicators. They are found in a wide variety of industries, but are especially important in those where safety is critical, such as industrial machinery, defense and aerospace applications. LED indicators are very versatile. Here are some of the LED indicator lights.

The drag chain is a device that binds cables or wires or air pressure pipes and oil pressure pipes to facilitate their rotation and movement. Energy chains are used to carry and protect cables, hydraulic pipes, gas pipes and other medium pipes, and to regulate the movement of medium pipes to avoid mutual entanglement, twisting and damage. Drag chains are spliced together by flexible unit chain links, and are widely used in platforms that require mobile power supply, such as: machine tools, construction machinery, welding and cutting equipment, electronics industry, logistics storage equipment, conveying equipment, injection molding industry, automobile manufacturing and other industries.
In fact, many UPS now also use lithium batteries, which can be integrated into standard racks. However, due to the limitation of volume, the battery capacity will not be very large. Correspondingly, the result is that the backup time is not long enough, and the rated backup time is maybe five minutes. Make sure that the server can be saved and shut down normally, or wait until the engine is powered on. But by 2022, in the current mainstream application solutions (95%+), UPS is still used in conjunction with lead-acid batteries. ATO uninterruptible power supply batteries are lead-acid batteries.

A linear servo motor is an integral part of a closed-loop system, providing thrust and speed based on commands from the servo controller using a feedback device to achieve a closed-loop.
According to the situation of the equipment, the power consumption environment and the purpose of power protection, a suitable UPS can be selected. For low-power equipment with a built-in switching power supply, a backup UPS can generally be used. Online interactive or online UPS should be used in areas with harsh electrical environments. For equipment that does not allow intermittent time or requires sine wave AC power at all times, only online UPS can be used.
Indicator lights include a colored lens such as red, green, blue, yellowr, clear, or white. These colored lenses symbolize the condition of the machine or equipment to which the lights are connected. Brightness is measured in lumens, while the energy a bulb consumes is measured in watts. To produce similar amounts of light, LED and fluorescents bulbs consume far fewer watts than incandescent or halogen bulbs. In this atrticle, laisteel.com will introduce dfferent colors of indicator light meaning.
Data acquisition is an interface that uses a device to collect data from outside the system and input it into the system. Data acquisition technology is widely used in various fields. For example, cameras and microphones are all data collection tools. The collected data are various physical quantities that have been converted into electrical signals, such as temperature, water level, wind speed, pressure, etc., which can be analog or digital. The data acquisition is generally a sampling method, that is, the data of the same point is repeatedly collected at a certain time interval (called a sampling period).
The indicator light is a panel-mounted lamp assembly consisting of the indicator housing, an internal lamp, terminals, and a lens. The light source of indicator light is a high brightness pure color LED or incandescent bulb. As the name implies, indicator lights reveal the status (ON or OFF) of an electrical apparatus in switchboards. In more sophisticated systems, the indicating lights may annunciate the cause of the current interruption, such as line-to-ground fault, overload, and overcurrent condition.
A terminal block (also called as connection terminal or terminal connector) is a modular block with an insulated frame that secures two or more wires together. It consists of a clamping component and a conducting strip. Many people are relatively unfamiliar with the terminal, because although we can use and see it in normal times, we don't know what it is and what it does.
