Wholesale 2 way ball valve Suppliers introduces the common faults of special motors for valves:

1. Low protection level: The special motor for valves provided by DENSO is a fully enclosed squirrel-cage structure and self-cooling with short-term intermittent duty (10min). According to the requirements of GB4942.1-85, the low protection level is IP44 and the protection level is IP68. Different valve operating conditions and environments require different protection levels. A low protection level will cause the motor cavity to be wet or dust and other foreign objects intrude, and the motor insulation resistance will drop and cause damage.

2. Improper packaging, transportation and storage: The valve electrical packaging should be protected from rain, moisture and dust, and the packaging should be firm and reliable. Rainproof measures should be taken during transportation, and the products should be stored in a ventilated and dry place after arriving at the site, and should not be stored in the open air. It is forbidden to debug or overhaul in rainy weather. After debugging, all fasteners should be tightened to ensure tight and reliable sealing of all electrical parts.

3. Failure of electrical protection and poor quality of electrical components: The micro switch in the valve electrical installation is a key component of the control mechanism. When the valve exceeds the stroke position, the micro switch cuts off the power supply and acts as overload protection. Most electric equipment manufacturers connect the stroke and torque protection in series. When overtravel or overtorque occurs, the micro switch will cut off the AC contactor coil control power in time, thereby cutting off the main circuit of the motor.
