How to reduce circuit failure caused by overheating of electromagnetic coil?

First of all, we need to understand the reason for the overheating of the solenoid coil. Research has found that in many cases, if the formation switch of the protection circuit is not turned on, this will cause the dedication coil to fail to automatically lose power, especially for a long time, which will naturally cause the coil to heat up.

1. Make the power supply voltage of the solenoid coil match the rated voltage. When the power supply voltage is higher than the rated voltage of the coil, it will increase the magnetic flux and cause the current in the coil to increase. If the voltage is lower than the rated voltage of the coil, the magnetic flux Decrease, the excitation current, regardless of which is unfavorable to the use of electromagnetic coils.

2. Multi-hydraulic check valve can be used to refurbish the limit coil. For example, the inner wall can be re-ground. If some parts of the interior have aging problems, in order to ensure the sensitivity of the product, it is necessary to replace the old one. new.

　　3. Transform the solenoid start valve. The specific method of transformation is to take out the spring inside and rely on the gravity of the spool to provide the gravity of the solenoid coil. The purpose of this is to reduce the water pressure on the solenoid coil and reduce heat generation.
