9, test bench speed: 1r / min
10, spray water: clean soft tap water Second, the device introduction
1. The water test equipment is mainly used to evaluate the outer casing and seal of electric and electronic products after the water test. Or whether the equipment and components can be guaranteed to have good working performance and technical status during the test. At the same time, the product may be affected by water intrusion during transportation or use, and provide reference basis for product technical standards;
2. This equipment is designed and manufactured according to the technical parameters of GB/T2423.38-2005 and GB/T 4942.1-2006, GB4208, GB4706 and GB7000. Applicable to the artificial rain test based on natural conditions, without strong wind speed rainfall, regardless of the high temperature of the test piece and the large temperature of the rain water temperature difference introduced;
3. The rain test equipment consists of four parts: swing tube bracket, swing tube drive, working rotary table and electric control. The bracket, rotary table cover and console are made of SUS304 stainless steel hairline plate.
Third, the working principle
1. Swing tube swing: It is realized by mechanical transmission of gear reducer, eccentric wheel mechanism and rack gear through motor and inverter (import). The frequency of the swing tube is adjusted by the frequency converter (unit time), and the angle is adjusted by the eccentric mechanism;
2. Rotation of the worktable: the motor drives the turbine to rotate and decelerate to achieve the rotation speed of the table;
3. Nozzle: Determine the bending radius of the pendulum tube according to the size of the test piece. The nozzle is a detachable special nozzle, and the nozzle hole can be replaced at any time according to the required aperture of the standard, so that the water droplets emitted are uniform and the flow rate is sufficient;
4, sewer: open-type pendulum rain must consider drainage, should be considered in civil construction, in order to be able to discharge quickly, not water is better. A tank of comparable capacity is required to supply the test.
Fourth, in line with the standard This product is manufactured strictly according to the corresponding national standard technical parameters such as GB4208-93, and can also be manufactured according to customer requirements.
