ZT ac contactor selection of several techniques and matters needing attention

Cast iron ac induction electric fan motor parts 

Specifications
1. 20 years manufacturing experience 
2. competitive price,high quality 

3. Type: iron body of AC electric motor 
Contactor is important low-voltage electrical components, the length of its life is one of the quality diesel engine evaluation and the main index, so it took some measures to improve life is very important. Suction characteristic and reaction characteristics of AC motor reasonable cooperation can improve the life of the contactor. The action of contactor voltage is 85% ~ 110% the Un. Contact closed suction and core make contact right of primary and secondary pumping, may lead to contact welding and increase its electrical erosion. Beating in order to reduce the contact time, small diesel engine should be properly reduced contact quality and speed, and appropriately increase the contact force early contact. For the acmotor2.blogspot.com second time in order to reduce and prevent contact bounce (at this time due to the large starting current, more serious harmfulness), in addition to borrow good cooperation from the suction characteristic and reaction characteristics in order to reduce the squirrel cage induction motor collision energy, still need to the water pump price electromagnetic water pump price system is equipped with buffer device to absorb the kinetic energy of such as armature. Finally selects the contactor, to pay attention to the use environment diesel engine of contactor, don't be too humid places in use, ac motor easy to make the contactor contact oxidation.
