Environmental Simulation Equipment
Characteristic
Salt spray test chambers generally have a small amount of solution storage, continuous testing requires the experimenter to frequently modulate the test solution to meet the test requirements. qs-CCT-S1 automatic replenishment of brine equipment is designed to reduce the workload of the experimental staff, up to 500L storage capacity of the equipment, the experimental staff in the touch screen interface to enter the quality of the formula added and the concentration of the solution required, the system will automatically replenish the corresponding volume of water and stir the solution through the internal circulation and motor mixing method. The system will automatically replenish the corresponding volume of water and stir the solution through the internal circulation and motor stirring method. After mixing, the system will automatically replenish the solution to two target devices (optional multiple devices). In addition, the system can be equipped with optional sensors such as PH detector and conductivity detector, which is convenient for experimenters to monitor the proportioning solution in real time.
Equipment specification
System implementation
l The solution tank water injection circuit is arranged with 50um filter to avoid debris from entering.
l solution tank designed with an overflow port, to avoid the system failure caused by the liquid level is too high
l brine pump suction port arranged with a filter, to avoid damage to the pump debris, to avoid debris into the target equipment
l solution tank bottom installation corrosion-resistant small-range high-precision pressure sensors, through the detection of solution tank pressure converted to the solution volume
l brine pump for fluorine plastic pneumatic diaphragm pump, corrosion-resistant
l all solution circuit solenoid valve are direct-acting PVC solenoid valve, corrosion resistance
l target equipment need to install brine tank low level switch and high level switch, and the signal into the automatic water replenishment system; when the low liquid level trigger, the automatic water replenishment system for the equipment to replenish the solution to the high liquid level
l Reasonable program design to realize automatic stirring of solution and ensure thorough and uniform stirring.
l Reasonable program design to realize automatic cleaning of solution tank.
Electrical control system
l PLC + touch HMI
l All sensor data are collected by PLC and displayed on HMI, including solution tank volume, solution PH value, solution conductivity, etc.
l All operations are operated by touch screen, including operation parameter setting (solution concentration, formula quality, target equipment activation, etc.), operation monitoring, operation startup, manual debugging, user management, alarm recording, etc.
