Brazed plate heat exchanger is a new type of high-efficiency heat exchanger made of a series of metal plates with a certain corrugated shape and then be brazing processed. Thin rectangular channels are formed between the plates, and heat is exchanged through the plates. Compared with the traditional shell and tube heat exchanger, brazed plate heat exchanger has a much higher heat transfer coefficient at the same flow resistance and pump power consumption. This article will introduce the installation and maintenance methods of brazed plate heat exchangers.

A wind turbine is a device that uses wind energy to drive blades to rotate, thereby generating electricity. Wind generator is generally composed of wind turbines, generators, tails, towers, speed-limiting safety mechanisms and energy storage devices. The principle of a wind turbine is relatively simple: the wind wheel rotates under the action of the wind, and converts the kinetic energy of the wind into the mechanical energy of the wind turbine shaft. The generator is driven by a wind turbine shaft to generate electricity.

The ultrasonic thickness gauge is a kind of portable measuring instrument that adopts ultrasonic measuring principle. The ultrasonic pulse emitted by the probe passes through the measured object to reach the material interface and the pulse is reflected back to the probe, so the thickness of the material can be determined by accurately measuring the time that the ultrasonic wave propagates through the material. The ultrasonic thickness gauge is suitable for a variety of material thickness measurements which can be propagated in its internal by the ultrasonic wave at a constant speed and can be reflected from the back...

The tension controller is a system developed by a microcontroller or some embedded devices and peripheral circuits. It is a control instrument. It can directly set the tension value to be controlled, and then directly input the signal of the tension sensor as the tension feedback value. After the deviation is obtained through comparison, it is input to the PID and other controllers for processing, and the obvious faults are eliminated in time.

The water-cooled magnetic particle brake is out of service for a long time. If there is accumulated water in it, it will be harmful to the rust prevention and moisture-proof work. Therefore, please install a special drainage valve on the water supply side to discharge the accumulated cooling water. Especially when it is used in high altitude or cold environment, the cooling water will freeze easily during the stop of operation, which may cause the water pipe of water-cooled magnetic particle brake to be damaged or broken once again. Therefore, the rust produced in the cooling water pipe must be cleaned regularly.

The ultrasonic cleaner makes use of the cavitation of ultrasonic waves to impact and eliminate the pollutants on the surface of the object, so as to wash quickly. It has the characteristics of high cleanliness and fast cleaning speed. Especially for blind holes and various geometrical objects, it has unique cleaning effects that cannot be achieved by other cleaning methods.

After receiving the product, many customers find that the power of the voltage stabilizer is too small, and the functions are not enough, resulting in returns and replacements, unnecessary shipping costs, and waste of time and money. ATO explains how to buy the correct automatic voltage stabilizer to you.

Plating rectifier is a rectifier power supply, which is simply a device that converts AC to DC. It has two main functions: First, it converts AC power to DC power and supplies it to the load after filtering, or to the inverter. Second, it provides charging voltage to the storage battery. Therefore, it also plays the role a charger at the same time.
ATO explains the installation steps of high-frequency electroplating rectifiers for you, so that you can install the rectifier correctly, and operate directly after you turn on the power.

In operation, small wind turbine uses wind and solar energy to generate electricity complimentarily, without the need for external power supply, thereby eliminating to a certain extent the construction of substations, high and low voltage lines, and high and low voltage power distribution systems. It has the characteristics of day and night complementarity and seasonal complementarity, stable and reliable system, as well as cost-effective performance.

Electric linear actuator mainly composed of motor, actuator and control device, which can realize remote control and centralized control. Electric linear actuators perform reciprocating motion within a certain range of strokes. Generally, the standard strokes of linear actuators are 100mm, 150mm, 200mm, 250mm, 300mm, 350mm, 400mm. Special strokes can also be designed and customized according to different application conditions. Electric actuators with different thrust can be designed according to different application loads. Generally, the maximum thrust can reach 12000N and the no-load running speed is 4mm ~ 35mm/s. The electric linear actuator uses a 12V / 24V / 36V / 48V DC permanent magnet motor as the power source, and converts the rotary motion of the motor into a linear reciprocating motion.

The resistance decade box is an electromagnetic relay that can adjust the resistor and display the resistance size of the resistor. If it is compared with the slide rheostat, the slide rheostat cannot express the resistance value of the connected power circuit, but it can continuously change the resistor in the connected power circuit. The resistance box can express the size of the resistance in the power circuit, but the resistance transition is not continuous. The role of the resistance box is that the resistance value of the circuit can be arbitrarily changed, thereby changing the current and voltage of the circuit.

The insulation performance of electrical equipment is usually judged by measuring its insulation resistance. In order to ensure the personal safety and the operation safety of electrical equipment, a minimum requirement is imposed on the insulation resistance between conductors of different phases or between the conductor and the equipment casing. In power engineering, the insulation resistance is measured quantitatively through an insulation tester, also called megohmmeter or megger, so as to determine whether there are insulation problems or hidden safety hazards.

The vibration motor is the core part of the vibration screening equipment. The excitation source combines the power source and the vibration source. It is a set of adjustable eccentric blocks installed at both ends of the rotor shaft. It will use the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block to obtain the exciting force. In addition, the vibration motor has a high utilization rate of excitation force, low energy consumption, low noise and long life. The excitation force of the vibration motor can be adjusted steplessly and is easy to use.

Rotary switch is a switch that controls the opening and closing of the main contact by rotating the handle. There are also two types of rotary switch structure, unipolar, single-position structure and multi-pole, multi-position structure. Single-pole, single-position rotary switches are often used together with rotary potentiometers in operation. Multi-pole, multi-position rotary switches are mostly used to switch operating conditions.

The vibration screen in the vibration motor is the key link for the smooth operation of the vibration equipment. When the excitation force is large, it is the main factor affecting the production efficiency. In order to extend the life of the vibration motor, the reasonable adjustment of the excitation force and the selection of a suitable power level cannot be underestimated. At the same time, it also plays an important role in the effective performance of the vibration motor.

Freeze dryer uses the principle of cooling and dew condensation, which is mainly composed of heat exchange system, refrigeration system and electrical control system. Compressed air first enters the pre-cooler for gas-gas or gas-water heat exchange, removing some of the thermal energy. Then it enters the hot and cold air exchanger and exchanges heat with the cold air that has come out of evaporator and cooled to the pressure dew point, which further reduces the temperature of compressed air. Compressed air then enters the evaporator and exchanges heat with refrigerant. Temperature of the compressed air drops to 0-8℃. The moisture in air is precipitated at this temperature, separated out by air-water separator, and discharged through automatic drain. The dry, low-temperature air enters the hot and cold air exchangers for heat exchange, and is output after the temperature rises.
