Abstract
A combined water pump composite fault diagnosis test apparatus belongs to a water pump fault diagnosis test apparatus. The combined water pump composite fault diagnosis test apparatus comprises a base. The surface of the base is provided with required number of T-shaped tanks. A plurality of independent brackets are arranged on the base through the T-shaped tanks. A motor and devices which are driven by the motor and can combine for generating a plurality of faults through moving and position change of the bracket in the T-shaped tanks are provided on the brackets. The devices comprise a test shaft, a gear case, a transition bearing base and a water pump. The combined water pump composite fault diagnosis test apparatus is characterized in that: a vibration sensor is fixed on the water pump; The vibration sensor is in data connection with a comparator. The comparator is in data connection with a PLC control system. The PLC control system is in data connection with a computer host. The combined water pump composite fault diagnosis test apparatus is advantageous in that: 1. vibration data of the water pump are detected through the vibration sensor; the comparator compares vibration data for finding a fault point; and 2. simple structure, easy operation, high data accuracy and small error are obtained; and analysis for different operation stations of the water pump in scientific research test is facilitated.
