Product features and process introduction:
1. The internal and external surfaces of the pipeline are of high quality, and the whole set of equipment materials do not have any welding points in contact with the pipeline, ensuring the pressure and corrosion resistance of the equipment. Simple operation, clean and hygienic, safe and reliable;
2. The pump adopts a pressure sensing system and a frequency conversion control system, which can adjust the pressure and flow rate by frequency conversion, and can set the maximum pressure to achieve automatic protection against overpressure. The use process is absolutely safe;
3. The membrane tank is designed to be rectangular, and the special flow channel design can ensure that the pressure and flow at each point of the membrane are stable and consistent;
4. Design based on fluid dynamics to ensure the tangential flow and turbulence of the membrane pool and ensure the reliability and stability of the test data;
5. Microfiltration membrane, ultrafiltration membrane, nanofiltration membrane and reverse osmosis membrane can be installed. Suitable for membrane test research and filtration experiment of a small amount of liquid;
6. A 60L (coiled tube) material tank is used, which can be connected to a temperature control cycle device for temperature control;
7. The equipment is equipped with an electronic digital pressure gauge with an accuracy of 0.4% FS to ensure the accuracy of the data and overcome the defect of low accuracy of the mechanical pressure gauge;
8. The membrane tank adopts a two-parallel four-series structure. Two sets of membrane tanks are measured at the same time or a single set of measurement. Different membranes can be installed at the same time, grouped or tested at the same time to ensure the consistency of the feed flow and state.

Main configuration components:
One high-pressure plunger pump, one pre-filter, eight SUS316L membrane cells, one set of electronic digital pressure gauges, two sets of mechanical pressure gauges, one set of coil material tanks, two pressure regulating valves, and five material control valves One, several pipes and their connecting parts, one set of rack, one set of overpressure control system, one set of frequency conversion digital display control system, and one set of refrigeration system.
