Washing Machine Door Endurance Test Machine

 1. Introduction

Washing machine door endurance test machine can meet the requirement of IEC60335-2-7 clauses 18.101 and 22.104, IEC60335-2-11 clause 20.101 and IEC60335-2-4 clause 18, it is a special test equipment applied to life test of lid or door interlock of various washing machines and tensile force test when the interlock device acts to lock the door. The washing machine door endurance test machine can be set flexibly as per different washing machine. The test machine adopts PLC controller and touch screen, and the motor drives the transmission rod to reciprocate the switch movement. It can independently realize the reciprocating action of "opening and closing" the lid and door of washing machine. The rack is made by high grade aluminium alloy, and the door is fixed by a vacuum suction cup structure, which is easy to operate and easy to control.


2. Test principle:

Use the edited program to control the power-on and power-off of the interlocking device, drive the mechanical arm through the motor, and drive the door or lid that is sucked by the vacuum suction cup to reciprocate opening and closing at a certain speed, so as to verify the reliability of the interlocking device. A force sensor is installed on the mechanical arm, which forms a closed-loop control with the servo motor, and can precisely control the closing force value.

UL746A High Current ARC Ignition Test Apparatus 32.5A/COSφ0.5

UL746A High Current ARC Ignition Test Apparatus 32.5A/COSφ0.5   1.  Introduction: The high current arc ignition tes t apparatus is designed according to  IEC60950-1:2001  clause 4.7.3.6 , BS/EN60950-1:2001, BS7002:2001, GB4943-2001 and UL746A, IEC60947.1:1999, GB/T14048.1-2000, IEC730.1:1993, GB14536.1-1998 and etc..  It ’ s used to measure and assess  solid insulating material against to resistance to ignition from arcing electrical sources. A power 240V(AC)/60Hz is to be supplied to the test electrodes  (fixed electrode and movable electrode) , a series (inductive-resistive) air core impedance is to be provided to yield a short circuit current of 32.5A and a power factor of 0. 5. The sample is be to positioned with the electrodes making initial contact on the surface of the sample, the circuit is to be energized and the cyclic arcing started. The timing of arcs is to be adjusted to a rate of 40 arcs/min, the rate of electrode separation is to be 254±...
