KP_1310M Japanese Standard Waterproof Testing Machine

This waterproof testing equipment is designed and manufactured based on the JIS D 0203-1994 standard, specifically for the four test types (R1, R2, S1, S2) outlined in "Test Methods for Moisture and Water Resistance of Automotive Parts." It is ideal for conducting moisture and water resistance tests on various automotive components, ensuring they meet industry standards.

The equipment features a stainless steel water pump for water supply. The flow rate is precisely controlled by a closed-loop system that includes a flow sensor, pressure sensor, PLC (Programmable Logic Controller), and frequency inverter. The flow sensor continuously monitors the flow rate and pressure, providing real-time data to the PLC. Using this data, the PLC adjusts the frequency of the inverter, which regulates the speed of the water pump to achieve the exact flow rate required for each specific test. Additionally, the system incorporates a Panasonic servo motor coupled with a gear reducer to drive the rotational motions necessary for the testing procedures. This setup ensures accurate and reliable performance during testing.
