PERFORMANCE TESTER FOR SHAFT SLEEVE OF VERTICAL TYPE PUMP

摘要

The present invention relates to a vertical pump shaft sleeve performance tester, the performance tester for testing the durability of the shaft sleeve is installed in order to prevent the spindle damage of the vertical pump, a motor having a rotating shaft, and is coupled with the rotating shaft to rotate together And a driving unit including a driving shaft in which the shaft sleeve as the test target is installed at an outer circumference; The upper frame is provided with a hole through which the motor is rotated and the rotating shaft of the motor penetrates, a lower frame fixedly installed on a bottom surface, and a hole provided between the upper and lower frames and through which the driving shaft can pass. A main body consisting of a support frame; A stuffing box fixed to an upper portion of the support frame and rotatably installed therein with a drive shaft and a shaft sleeve, a packing wound around the shaft sleeve under test in the stuffing box, and a fastener at an upper portion of the stuffing box. A test part comprising a packing presser for pressing the packing downwardly; A cooling unit comprising a storage tank, a cooling water supply line, and a circulation pump for supplying cooling water to the test unit; And an operation unit for controlling the operation of the driving unit and the cooling unit. According to the present invention, since the same structure as the vertical pump used in practice, the performance of the shaft sleeve can be evaluated under the actual driving conditions, and the sleeve or packing can be easily installed and replaced during the performance test of the shaft sleeve. And, there is an advantage that can set the optimum operating state of the pump according to the pressure between the packing wound on the shaft sleeve or the flow rate of the cooling water supplied.
