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? For this issue, ATO.com will give you a brief explanation so that you can have a more detailed understanding of these two pumps.

Soldering stations and soldering irons are common tools in soldering operations. In fact, the soldering station is also a kind of electric soldering iron. Many people call the soldering station an electric soldering iron. The soldering station is just a new welding tool that appears in the electronic welding process due to the development requirements of welding technology. Now the soldering station has developed a lot.

A proximity switch is a position switch that can be operated without direct mechanical contact with moving parts. When the object is approaching and the sensing surface of the switch is at the action distance, the switch can be actuated without mechanical contact and any pressure to drive the DC electrical appliance or provide control instructions to the computer (plc) device. ATO proximity switch is a non-contact switch. It not only has the characteristics of a limit switch and microswitch but also has sensing performance.

Both voltage stabilizer and voltage regulator are power protection devices. The voltage regulator can adjust the required voltage according to the actual situation of the user. The voltage stabilizer can only stabilize the fluctuating and unstable voltage at the preset voltage value in the factory. Although both the voltage stabilizer and the voltage regulator change the voltage, but their functions are different. You could choose according to the actual situation.

The automatic holding circuit is often used in various electrical cabinets and is a simple logic circuit. Of course, this simple logic circuit can be built in a large number of PLCs, it is the basis of PLC logic instructions.

Solar radiation sensor is designed on basis of silicon-cell principle. It is mainly used for measuring solar radiation within 300-1100nm wavelength. If the sensing face is downwards, it can test the reflected radiation and solar radiation on the incident to the inclined plane. PAR sensor is mainly used for measuring solar radiation within 400-700nm wavelength. It is easy installation and can work continuously in all weathers. When there is sunlight, voltage output proportional to incident light intensity will be generated by the silicon-photo detector in the sensor. 

Diaphragm pump is divided into air powered diaphragm pump and electric operated diaphragm pump. Pneumatic diaphragm pump is a new type of conveying product that uses compressed air as the power source. It can absorb all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids. Material is available in aluminum alloy, stainless steel, non-metallic and cast iron. Electric diaphragm pump is also a new type of pump, which is used in petrochemical, ceramics, metallurgy and other industries.

A stepper motor is an actuator that converts electrical pulses into angular displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction, and its rotation runs step by step at a fixed angle. The angular displacement can be controlled by controlling the number of issued pulses, so as to achieve the purpose of controlling the displacement. At the same time, the speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation. The rotor inside the servo motor is a permanent magnet.

A circuit breaker is essentially a safety device for any property that uses electricity. These fixtures act as third parties in complex and dangerous electrical wiring systems. MCB and MCCB are circuit breakers. They are used in homes to prevent personal injury and electrical damage. These devices are designed to perform specific functions. It is their special features that make them special. So, what are the differences between them?

Proximity sensors are known as non-contact travel switches which are generally widely used in material sorting control systems and automatic detection. Proximity sensors are divided into inductive proximity sensor, capacitive proximity sensor, magnetic proximity sensor, analog proximity sensor and Hall proximity sensor, which can detect whether there is an object approaching within a range of several millimeters to tens of millimeters. When the distance between the object and the proximity switch reaches a certain range, this proximity sensor can send out the corresponding action signal.

Vacuum contactor is a device that can withstand multiple operations (strong mechanical life). It can cut off the load current at the same time, but can not break the short-circuit current. The vacuum contactor has two contacts, normally open and normally closed, and does not have the function of short-circuit current protection. When a given signal is received, it can perform separation and hold actions. Analogus to ordinary home circuit, VCB is like a circuit breaker at home inside a panel and VC is a relay in our any of instruments at home.

What exactly is the difference between incremental and absolute encoders? An absolute encoder can tell you the exact position of the shaft in its rotation at any given time (and how many rotations have transpired on a multi-turn absolute encoder). An incremental encoder can only report a change in position. It may not sound like a big difference, but it's night and day if the system has a loss of power. Once power is restored, an absolute encoder can report exact position without any movement. An incremental encoder will need to find an Index or home position before it can do so – and if it doesn't have an index, it won't be able to tell you it's position at all.

Optical fiber is a flexible transparent fiber made of extruded glass or plastic, slightly thicker than human hair. Optical fiber is the most commonly used means for transmitting light at both ends, and it is widely used in optical fiber communications. Optical fiber has longer transmission distance and higher bandwidth than wired cable. An optical fiber is usually composed of a transparent core with a low refractive index and a transparent cladding material. As an optical waveguide, the optical fiber causes total reflection of light in the core.

Induction motor for sale, also known as "asynchronous motor", is a device that puts the rotor in a rotating magnetic field and obtains a rotating torque under the action of the rotating magnetic field, so that the rotor rotates. The rotor of an induction motor is a rotatable conductor, usually in the shape of a squirrel cage. According to the type of alternating current, there are single phase induction motors and Three phase induction motors. So what is the difference between them? This is mainly reflected in the following aspects.

When a single phase induction motor is working, it will involve the problems of start capacitor and run capacitor. Because single phase is different from three phase, a single phase motor cannot form a rotating magnetic field when it is started, and uses the characteristic of the current in the capacitor to generate a rotating magnetic field to start the motor. Therefore, the start capacitor in a single phase motor is essential. But the run capacitor is not necessary.

In terms of usage, the servo motor is mainly responsible for the feed of the machine tool, making the workpiece move to the tool or the tool move to the workpiece, mainly to realize the work of cutting, with higher requirements for torque and control accuracy; while the spindle motor is mainly responsible for driving the spindle of the machine tool, driving the workpiece or the tool head to rotate, with higher requirements for constant power characteristic output to meet the sufficient torque output capability at different speeds. Therefore, when designing, these two motors will make targeted parameter optimization according to their application requirements respectively.

First of all, in terms of flexibility, drag chains are more flexible than ordinary cables. Although the monofilament diameter of the drag chain cable conductor is small, in order to protect the conductor, an insulating material with resistance to mechanical fatigue and a certain strength must be selected. The requirements of tensile resistance, bending resistance, strong wear resistance, anti-blocking, and high toughness also determine that the protective cover material should also have a certain degree of hardness. Therefore, the flexibility of the drag chain is high flexibility, not high flexibility.

Safety switch is a switch that prevents people from entering a dangerous area before all safety conditions are met. Also it is a device that monitors current in various applications. Safety switches can be used in major equipment applications (conveyor belts, production line equipment, heavy equipment) and electrical protection of whole system. The safety switch works by monitoring the current and detecting electrical faults, which means that in case of leakage, short circuit, overload, the safety switch will cut off the power supply of the faulty system almost immediately (within a few milliseconds).

The servo motor can make the speed and position control accuracy become very accurate, and can convert the voltage signal into torque and speed to drive the control object. The speed of the servo motor rotor is controlled by the input signal and can react quickly. In automatic control systems, servo motors can be used as actuators. Servo motor has the characteristics of small electromechanical time constant and high linearity, and it can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It can be divided into two categories: DC and AC servo motors. Its main feature is that there is no autorotation when the signal voltage is zero, and the speed decreases at a uniform speed with the increase of torque.
