XQ-J86 Water Testing Machine 
I. Scope of application of the water testing machine： 
This equipment is mainly used for testing the flushing function, sealing performance and flow rate of sanitary ceramics. The machine is equipped with an imported touch-type human-machine interface and a programmable controller (PLC) as the core of the system control, which is perfectly integrated with various mechanical execution components to ensure the long-term stable operation of the system. During the testing process, it is convenient to quickly set and read various test parameters and test data in a conversational manner. In the design structure. 
II. Testing standards for the water testing machine：
Comply with the GB6952-2005 standard in the bathroom industry. Maximize the redundancy capacity of the equipment and follow the GB 6952-2005 (Hygiene Ceramic) standard. 
III. Introduction to the Water Testing Machine： 
1.When testing the incoming water flow rate, only one workstation can be selected for the test, and the same incoming water flow meter is shared. 
2. This equipment has 2 working positions. During the testing process, only one position can be selected for testing. This design offers more precise control over the test accuracy compared to similar products. 
3. By adopting variable frequency constant pressure technology, the applicable working conditions of multi-stage centrifugal pumps have been expanded. This enables the equipment to automatically adjust various working conditions using only one water booster device, with low noise. The variable frequency control ensures a stable and reliable system with high controllability. 
4.The equipment has excellent scalability. It can be expanded in terms of functions and workstations by modifying the original system as per requirements. 
5. The operability of the equipment, the multi-functional tooling fixtures, are easy to operate and can uniformly hold multiple samples on the testing platform. 
6. Monitoring Function: It can monitor the real-time status of analog quantities such as pressure and flow rate, as well as switch quantities such as the number of tests and the movement condition of the system. The system will adjust and control in real time based on the detected values or the set values. 
7. Expandable Function: It can conduct tests on water tank accessories and faucets, etc. 
8. The system should be capable of easily conducting tests on the flushing performance of sanitary ceramics. The test media such as PP balls and PE particles should be able to be counted and removed conveniently. 
9. The equipment is equipped with a drawer-type sieve for filtering out large and small PP balls and PE balls. It is convenient and quick to remove and reuse. 
10. The test medium for this test bench is water (room temperature water). Therefore, the main flow components and water tank of the equipment should be made of stainless steel or copper to ensure a reliable service life under different working conditions such as long-term operation and intermittent operation. 
11. In terms of data collection and display, all adopt the latest sensor technology. The test conditions, parameters, pressure, etc. that need to be adjusted and monitored during the testing process are automatically and continuously tracked and collected, and displayed on the human-machine interface of the instrument and industrial touch screen. In terms of control methods, a combination of high-performance imported programmable controllers and industrial touch screens is adopted, which can realize various control functions such as workstation selection, test item type selection, test project selection, temperature control parameters, conversion cycle, and test times, etc. Its outstanding advantages also lie in the fact that each workstation can independently set the action frequency, conversion cycle, and test times, and has intelligent control functions such as independent pause or termination of the test, re-changing the test piece (or re-clamping), re-recording the number of actions, automatic shutdown, and beeping and flashing alarm. 
12. Summary of Equipment Characteristics: This equipment is controlled entirely through touch screen. 
13. Safety Function: The equipment is equipped with overload protection function. In case of overload or leakage, the equipment will automatically stop. The water tank is equipped with a water level indicator. When the water tank is at a low water level, the water supply will be automatically activated through the solenoid valve. 
14. Constant pressure water supply: An imported high-precision pressure sensor is installed in the middle of the water supply pipeline. When the pressure is too high or excessive, the pressure sensor will send a feedback signal to the frequency converter. Upon receiving the signal, the frequency converter will automatically calculate and control the pump frequency, thereby achieving the constant pressure function. Both dynamic pressure and static pressure are set at the specified pressure. 
IV. Main features of the water testing machine：
1.This device is controlled entirely by touch screen. 
2.One human-machine interface is installed on this machine. 
3.The placement of the products will be designed with thickened steel plates and sturdy frames, which are capable of supporting products weighing 30 to 80 kilograms without deformation. The stainless steel countertop is equipped with good rubber protection and will not scratch. 
4. Install a drawer-type filter ball at the water outlet. During the test, all the water is flushed into the net. When using it again, simply remove the filter ball and place it inside the item being tested. 
V. Notes for the water testing machine： 
1.Before conducting the test, please make sure that the power supply is properly plugged in or connected. 
2. Before conducting the test, make sure that the product is properly installed and fixed. 
3. The mechanical transmission parts must be maintained regularly. 
4. After the test is completed, it is necessary to ensure that the power supply has been turned off. 
5. It is strictly prohibited to use auxiliary corrosive liquids to clean the machine. Instead, rust preventive oil must be used. 
6. This testing machine must be used exclusively by one person. During the testing process, it is strictly prohibited to strike the machine or have anyone stand near it. 
7. The machinery must be grounded.
