What should I do if the geothermal exhaust valve leaks

Water leakage from the geothermal exhaust valve is very common. Under normal circumstances, when the heating is first delivered in winter, the geothermal pipe needs to be exhausted so that the exhaust can make the heating of the underfloor heating loop uniform.

Dewatering device in Fusheng air compressor

During the compression work, part of the lubricating oil must be mixed into the compressed air, which will cause some failures in the pneumatic circuit, damage the pneumatic components, reduce the service life of the components, reduce the production efficiency, and even cause accidents.

Common failure and analysis of centrifugal air compressor

Common failure and analysis of centrifugal air compressor 1. Abnormal vibration and noise: ① Misalignment ② The compressor rotor is unbalanced ③ The impeller is damaged ④ The bearing is abnormal ⑤ The coupling is faulty or unbalanced ⑥ The sealing ring is bad ⑦ The oil pressure and oil temperature are abnormal ⑧ There is dirt in the oil Clean, wear out the bearing ⑨ Surge ⑩ The stress of the gas pipeline is transmitted to the casing, which causes misalignment ⑪ There is a machine working near the compressor<img src="{{media url=&quot;Common_failure_and_analysis_of_centrifugal_air_compressor.jpg&quot;}}" alt="" />

The main difference between brushless DC motor and DC servo motor

Different definitions: (1) Brushless DC motor is a typical mechatronics product, which is composed of motor body and driver. Brushless motor refers to the motor without brush and commutator (or collector ring), also known as commutator less motor. As early as the 19th century, when the motor was born, the practical motor was the brushless form, that is, the AC squirrel cage asynchronous motor, which has been widely used. However, the asynchronous motor has many insurmountable defects, so that the development of motor technology is slow. The transistor was born in the middle of last century, so the brushless DC motor using transistor commutation circuit instead of brush and commutator came into being. This new type of brushless motor is called electronic commutation DC motor, which overcomes the defects of the first generation of brushless motor.
