Quickly master the secrets of the use of laboratory ultrapure water

       The laboratory ultrapure water device is a device that filters particles such as dust and sediment and absorbs odors from tap water. It can make the tap water cleaner, so that the water quality can reach the standard of third-level water. In order to make it better for novices There are many details that need to be paid attention to when using the equipment. Let's talk about it in detail below.

In order to facilitate the installation and opening and closing of the laboratory ultrapure water device, it is recommended that the water inlet be separated from the device by 1-2 meters. When replacing accessories, it is convenient to close the water inlet, and at the same time, the water production efficiency will not be affected by the long pipeline. If there is enough space in the laboratory, try not to have too much voltage fluctuation and strong electromagnetic interference around the equipment, especially the equipment with water arm and remote control function. If conditions permit, a waterproof cover can be added to effectively protect the power supply when there is a problem with the pipe or when the replacement parts are improperly handled and water is sprayed.

After the water is energized, the pressure of the raw water closes the low pressure switch, and the circuit forms a path at this time.

After the circuit is connected, the water inlet solenoid valve opens and the water pump starts.

After being pressurized by the high-pressure pump, the raw water permeates through the diaphragm, and the pure water comes out from the water outlet of the pure water machine, and the concentrated water follows the

After the pure water passes through the check valve, it reaches the high pressure switch. Its main function is to disconnect the circuit when the water is full.

The waste water from the waste water outlet passes through the flushing valve and the waste water ratio (or combined flushing solenoid valve). When flushing, the flushing valve is opened, and the impurities on the membrane surface are flushed by the pressure of the water pump. Rinse state, no pure water.

The waste water is discharged from the outlet. There is a fitting at the pure water outlet - a check valve, also called a one-way valve, whose function is to prevent the backflow of pure water.

Pure water enters the pressure bucket, and the pressure bucket stores pure water. When the gooseneck faucet is closed and the pressure bucket is full, a pressure is formed between the gooseneck faucet and the one-way valve. After reaching the starting value of the high-pressure switch, the high-pressure switch Disconnect, the machine stops.

After the equipment is flushed, the flushing valve is closed, the water passes through the waste water ratio, and there is enough osmotic pressure in the membrane shell to allow the water to pass through the membrane and ensure that the pure water flows out.

The above are the main points that need to be paid attention to in the use of laboratory ultrapure water equipment. Users need to have a certain understanding of it before using it, especially in the details of use, which is conducive to improving our own work ability and post-operation level.
