The electric ball valve is driven by an electric actuator and has the action of rotating 90°. It is mainly used for cutting, distributing and changing the moving direction of the medium.  The electric ball valve has the characteristics of compact structure, stable performance and convenient installation. It has been used more and more in many industries. It can be operated on site or controlled remotely. It is one of the final control elements in the field of automatic control. Electric ball valves may leak during use or installation.

Pneumatic actuated ball valve is different from manual valve. It needs to be in motion and adjustment state during use, and there are many moving parts, and it also bears the impact of various forces such as the unbalanced force of the medium. It is inevitable that various unexpected failures will occur. These failures could be actuators, regulators, and possibly from attached accessory devices. When a fault occurs, it must be dealt with and solved in time, so as not to delay the operation of the equipment of the entire project. Next, let's take a look at the common failure causes and solutions of pneumatic ball valves.

Thermal overload relays are protective appliances used for overload protection of motors or other electrical equipment and electrical lines. In the actual operation of the motor, for example, in the process of dragging the production machinery to work, if the machinery is abnormal or the circuit is abnormal and the motor is overloaded, the motor speed will drop and the current in the winding will increase, which will make the winding temperature of the motor. If the overload current is not large and the overload time is short, and the motor winding does not exceed the allowable temperature rise, this overload is allowed.

However, many customers have some problems in the process of using the AODD pump. Then, we will troubleshoot the air diaphragm pump next.

As the application and ambient temperature change, DC cooling fans with different speeds are sometimes required to meet the cooling requirements of the device, and the DC cooling fans pass through. A heat dissipation device that converts electrical energy into machinery to drive fan blades through DC voltage and electromagnetic induction. In simple terms, the coil and the IC are constantly switched, and the induction magnetic ring starts to rotate from the fan blade. Therefore, it has good heat dissipation effect and is widely used. In this article, we will introduce some methods to deal with common faults of direct current cooling fan.

A well pump refers to a water pump that submerges the impeller into a well to pump water. According to the depth of groundwater extraction, it is divided into deep well pump and shallow well pump. A well pump with a lift below 50 m is called a shallow well pump, and a well pump with a lift above 50 m is called a deep well pump.

Automatic transfer switches play a vital role in emergency power supply systems. These devices aid in the safe transfer of power from mains or mains to backup generators. After the automatic transfer system detects a power failure, it invokes a backup power source as an intermediary between the device and the power source. These steps are reversed when returning to regular power. Before changing between sources, the switch will verify that the supply is at the desired parameters and stable. While these devices ensure the safety and reliability of backup power, some issues can prevent the device from working properly. In this article, we will introduce common problems in auto changeover switch.

NDIR CO2 sensors monitor and detect for the presence of carbon dioxide based on the absorption of infrared light at a specific wavelength. An NDIR sensor comprises an infrared source, a light tube, a bandpass filter, and a detector. The target gas is determined through the filter wavelength choice.

Machine tool work lights are lamps suitable for various large-scale construction operations, emergency repairs, rescue and disaster relief and other work-site lighting. Widely used in various small and medium-sized machine tools, CNC machine tools, experimental equipment, closed machine tools, combined machine tool lighting, medical equipment, ship maintenance, equipment maintenance work lighting. Some can also be used in processing centers, commodity exhibitions and other places.

The inverter converts DC (batteries, accumulators) to AC. In general, an inverter is an electronic device that converts low-voltage (12, 24, 48 volts, etc.) DC power into 220V AC (or other voltage) power. It consists of an inverter bridge, control logic and filtering circuit. When there is no output from an inverter, what's the reason?

Explosion-proof motor is a special kind of electrical equipment with great danger. Once rust and rust spots appear on the explosion-proof surface, and the contact surface is not in good contact, harmful media will take the opportunity to enter, corroding the parts and winding insulation in the machine, and once the explosion-proof motor loses its explosion-proof performance, the consequences will be disastrous. Therefore, it is very important to find, repair and eliminate explosion-proof motor failures in time.

Through the electroplating rectifier, the AC power can be changed to DC power, which also shows the importance of the electroplating rectifier. We will encounter some failures in using the rectifier, and this article will introduce the plating rectifier troubleshooting.

Traditional molded case circuit breakers use electromechanical (thermal-magnetic) trip units that can be fixed or interchangeable. MCCBs provide protection by combining temperature sensitive equipment with current sensitive electromagnetic equipment. Both devices act mechanically on the trip mechanism. In the use of molded case circuit breakers, various faults will be found, and frequent tripping of molded case circuit breakers is one of the common fault phenomena.

The servo driver is a controller used to control the servo motor. Its function is similar to the frequency converter. It is used for ordinary AC motors. It is a part of the servo system and is mainly used in high-precision positioning systems. Generally, the servo motor is controlled by three methods of position, speed and torque to achieve high-precision positioning of the transmission system. In order to ensure the normal operation of the equipment, it has become a very important task to judge the fault in time and deal with it in time. Here we will introduce the analysis and troubleshooting of the AC servo motor driver.

In recent years, although the quality of endoscope has been steadily improved, as a kind of precision equipment, improper operation and collision caused by random placement of instruments may cause damage to precision optical components. The damage of industrial endoscope has the following aspects: image optical resolution is reduced and image blur; field of view size is changed; image transmission distortion or halo phenomenon; the image is blurred or too dark.

Motor problems are the most common and annoying problems faced by every compressor user. When the motor fails, it can cause a lot of trouble.

When the hydraulic electric pump is in the self-priming state, if the oil inlet pipeline leaks or there is a large leak in the hydraulic cylinder, check valve, reversing valve, etc. in the system, the pressure will not rise. This requires finding the air leak, tightening and replacing the seal, and the pressure can be increased. The overflow valve is faulty or the adjustment pressure is low, and the system pressure cannot go up. The pressure should be re-adjusted or the overflow valve should be repaired. If the cylinder block of the hydraulic pump deviates from the valve plate and causes a large amount of leakage, the cylinder block may be broken in severe cases, and the mating surface should be reground or the hydraulic pump should be replaced.​​
