As the key elastic element of the diaphragm coupling, the diaphragm bears the main load during operation. When the diaphragm shaft coupling rotates, its angular offset will generate alternating stress, which alternates once per rotation. The dynamic stress of the diaphragm will lead to the fatigue damage of the diaphragm and the bolt, so the accurate calculation of the dynamic and static composite stress is the key to predict the life of the diaphragm shaft coupling and the operation of the diaphragm shaft coupling.

Static eliminators are products that protect susceptible items from the effects of static discharge. There are rules that must be followed in static elimination. A thorough understanding of these principles is necessary to obtain the best performing equipment. The following will clarify some issues to consider when choosing static elimination.

Compared with piston motors of similar power, vane air motors are smaller, lighter and less expensive. Simple design and construction allow them to operate at any installation angle in most cases. The vane motor has a wider range of speed, torque and power and is the most commonly used form of air motor.

Shaft couplings are mechanical parts used to connect two shafts (driving shaft and driven shaft) in different mechanisms to rotate together to transmit torque. In high-speed and heavy-duty power transmission, some couplings also have the functions of buffering, damping and improving the dynamic performance of the shafting. The coupling consists of two halves, which are respectively connected with the driving shaft and the driven shaft. Most of the general power machines are connected with the working machine by means of couplings.

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.

Today we are going to carry out vibration motor performance test. This is 220V input. (Force is 30kg) vibration motor. The rated current and power are 0.1A and 30W respectively. We are able to open one side of cover. Now we can see, adjustable eccentric block is connected end of rotor shaft. Both two sides of the nut are same construct. The eccentric block is used to obtain the exciting force. The combination of the specific designed motor and the eccentric block enable the motor to rotate.

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). 

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. 

Induction motor refers to a motor that relies on electromagnetic induction between the stator and the rotor to induce current in the rotor to realize electromechanical energy conversion. Three-phase asynchronous motors generally have two wiring structures, WYE (Y) and Delta (△). When the Y-type access voltage is 380V, we can change it to △ type 220V.

The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to be rotated 90 degrees and a small torque can be closed tightly. Ball valves are widely used in petroleum refining, long -distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electric power, municipal, steel and other industries. ATO offers one piece, two pieces, three pieces of stainless steel ball valves, sizes are available in 1", 1/4", 2' and 3"

ATO UPS is the abbreviation of the uninterrupted English name, which appeared with the birth of the computer and is one of the commonly used peripheral devices of the computer. Actually. UPS is a kind of uninterruptible power supply with constant voltage and constant capacity with an energy storage device and inverter as the main component. Now that UPS is becoming more and more popular, let's take a look at the main protection functions of uninterruptible power supplies?

Centrifuge machines are widely used in various laboratories such as hospital laboratories, scientific research institutions laboratories, food and drug testing laboratories, and food hygiene laboratories. Centrifuge selection should pay attention to the following aspects.

Terminal block is an accessory product used to realize electrical connection, which is divided into the category of connector in industry. With the increasing degree of industrial automation and the stricter and more precise requirements of industrial control, the amount of terminal blocks is gradually increasing. The following small series will introduce to you how to connect the wiring terminals.

Household UPS is to provide power supply for computers and other related products in the family, just like conventional UPS is different from industrial UPS. When choosing a home UPS uninterruptible power supply, you should choose genuine brand products. For those who do not know about various professional power matching and power supply times, you can directly consult ATO customer service. ATO.com is a professional R&D, production and manufacturing UPS company, and the manufacturer ships directly.

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 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.

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.

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.

An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators.

The use of air compressors is very extensive. It can be used in instrument control and automation devices, such as tool change in machining centers.
