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.

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.

Rotary switch is a multi - loop control appliance which is made up of several contact components of the same structure. It consists of operating mechanism, positioning device, contact, contact system, rotating shaft, handle and other components. The contact is in the insulating base, double breakpoint contact bridge structure, the moving contact is designed to automatically adjust to ensure the synchronization of on-off, static contact is installed in the contact seat. The use of CAM and bracket operation, control contact closure and disconnect.

Miniature circuit breaker, short for MCB, is one of the most widely used terminal protection appliances in building electrical terminal distribution devices. And this article shows the right selection of MCB based on its electrical parameters. The rated breaking capacity of MCB is the maximum short-circuit current value that can be broken without any damage to the circuit breaker. The miniature circuit breakers currently on the market generally have several rated breaking capacities, including 4.5kA, 6kA and 10kA according to the relevant technical data and design manuals provided by various manufacturers.

With the development of technology and rising labor costs, more and more enterprise factories are using automation, such as machining. The ATC spindle motor is also an integral part of machining. It brings great convenience to everyone and improves production efficiency, but at the same time, there are some problems. Let's talk about some common problems and solutions of automatic tool change spindles.

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.

With the development of industrial technology, automatic tool changing spindle is widely used. Automation has gradually become the main form of enterprise production and processing. So, what should we pay attention to in use?

• ATC spindle motors and VFD should be used together. The specifications and parameter settings of the VFD should match the rated parameters of the spindle.
• When using, first check whether the air duct is blocked or not, and use compressed air to blow through it in emergency use.
• The cooling circulation system must be in normal operation before use. Do not use without cooling
• Water cooled motors must ensure that the coolant must be clean.

With the advancement of science and technology, various industries have higher and higher requirements for power supply reliability. Two power sources must be used to ensure the reliability of the power supply in many occasions. In the past, the users of the two way power supply used a manually operated two-way isolation switch on the low voltage side to perform the switch off operation, so misoperations often occurred and accidents were caused. With the improvement of power supply reliability requirements and the improvement of anti-accident measures, more and more advanced equipment has been put into application in the power supply system.

It is necessary to cool and dissipate the automatic tool change electric spindle, especially in high temperature. If you find that the electric spindle is overheated during the application process, then you should consider whether to take heat dissipation measures. Do not allow the electro-spindle to run in overheating conditions, which will affect the service life. ATO will introduce to you two cooling methods for spindle motors.

In level control and detection applications, the level of a tank or container will change at a continuous rate over a period of time. In order to know when a failure occurs or when levels become dangerously high or low, it is critical to have a level control monitoring solution in place to prevent costly damage and situations where water overflows or runs dry. The following mainly describes the functions of the photoelectric liquid level switch in the water tank or container.

Cable float switch is a commonly used water level controller. It has a simple structure, convenient installation and sensitive control. The following is the wiring and installation method of cable float switch for your reference.

The absolute value rotary encoder is a detector that can output the angle data within one revolution of the motor to an external target. Absolute encoders are generally capable of outputting 360° with 8 to 12 bits. There are many optical channel engraving lines on the absolute encoder optical disc, and each engraving line is arranged with 2 lines, 4 lines, 8 lines and 16 lines in turn, the shaft encoder obtain a set of unique binary codes (Gray codes) from the zeroth power of 2 to the n-1th power of 2.

With the development of industrial technology, automation has gradually become the main form of enterprise production and processing. In machining, the tool needs to be changed frequently due to different materials or shapes. The high speed motorized spindle has also been continuously developed from the traditional manual tool change to the ATC.

The rear end of the electric spindle is a cylinder structure. It uses air pressure to push the thimble against the middle pull rod so that the collet extends outward and the tool falls off, and then the device can automatically grab the tool using the shaft platform. The rear end of the spindle uses a solenoid valve to release the air and cut off the air so that the tool is clamped. This process is called automatic tool change.

The working principle of dosing pump is relatively simple, but because it involves highly corrosive liquid and high-precision flow, it has very high requirements for every part and every process of the machine. When the coil of the electromagnet is charged, the iron core pulls the electromagnetic push rod together, and at the same time, the corresponding five springs are compressed and the liquid is quantitatively sucked in. And when the coil of the electromagnet loses power, due to the disappearance of the electromagnetic force, the compressed 5 springs will be released, so that the liquid is quantitatively discharged.

The DC-DC converter is a voltage converter that effectively outputs a fixed voltage after converting the input voltage. DC to DC converters are divided into three categories: step up DC-DC converters, step down DC- DC converters, and buck-boost DC-DC converters. Three types of controls can be used according to requirements. At present, DC to DC converters are widely used in products such as mobile phones, MP3s, digital cameras, and portable media players.

A brushed DC motor is a rotating motor that converts DC electric energy into mechanical energy or converts mechanical energy into DC electric energy with a built-in brush device.
