Method for Extending the Service Life of Ultra Pure Water Machine

1. Environmental requirements for installation site

The installation position of the laboratory ultra pure water machine is very important, and do not easily move it after placing it. So how do you choose this position?

01. Sufficient operating and maintenance space should be left around the equipment;

02. Do not place the water machine in an environment with high acidity, and the discharge outlet should be lower than the equipment wastewater discharge outlet;

03. Smooth drainage (the shorter the distance from the wastewater discharge outlet to the drainage ditch, the better);

04. The environment must be ventilated and dry, with an ambient temperature of 5-45 ° C. If placed in a damp and non ventilated environment, it can cause microbial growth and affect the water quality of the equipment; Electrical components are damaged; Equipment racks and other materials are corroded;

05. When the equipment is transported from an outdoor environment with a temperature below 0 ° C to the place of use, it needs to be placed indoors at a temperature above 13 ° C for 24 hours before it can start up and run.

06. Do not move the water machine arbitrarily. If the equipment is frequently moved, improper vibration during the process may have an unpredictable impact on the connection of its internal accessories. Therefore, after selecting the location and installation, try not to move or vibrate arbitrarily.

2. Keep equipment clean

For the exterior of the pure water machine, simply clean it with a clean damp cloth and avoid using soap or cleaning agents as much as possible. For the interior of pure water machines, current pure water equipment generally has an automatic flushing function, which is achieved every time it is used.

3. Timely core replacement

The filter element is the "soul" of the water machine, and regular and timely replacement is necessary to ensure water quality and maintain stable operation of the equipment.

Generally speaking, the pre-treatment filter element of pure water equipment can effectively filter out sediment, rust, algal particulate impurities, residual chlorine, iron manganese metal ions, etc. in the source water, and also has the effect of inhibiting microbial growth such as bacteria, greatly improving water treatment efficiency and providing a certain degree of protection for the equipment. Its service life is generally 3-6 months (the replacement cycle is mainly determined by the local actual water quality and user usage habits).

RO reverse osmosis membrane is the core component of a pure water machine, with a service life of 1-2 years (the replacement cycle is mainly determined by the local actual water quality and user usage habits); The purification column is expressed online through electrical resistivity, and below a specific resistance indicates that the purification column has expired, which is very intuitive.

If consumables are not replaced for a long time, it will not only affect the purification effect, but also damage the service life of other filter elements, making the equipment run slowly.

4. Long term no need to cut off water or power supply

When the laboratory does not use the ultra pure water machine for a long time, the inlet water valve should be closed and the power supply should be cut off. If there is no use for more than 30 days, the water circuit and circuit should be checked for normal operation before use. Before using water, RO water must be drained first. After the water quality meets the standard and drops to a certain value, UP water can be taken. If the UP water is taken directly without using the equipment for a long time and the inlet conductivity is high, it will cause rapid failure of the ultra purification column. If the water quality is abnormal, consumables need to be replaced as soon as possible before use. If there are any faults, please contact after-sales engineering for resolution in a timely manner.

5. System status

For long-term use of water systems, aging of electronic components, pipelines, and other components often occurs, which not only affects the service life of the equipment, but also affects laboratory safety. Regarding equipment operation, we need to confirm the operating status of the system, mainly including: circuit system, waterway system, system software, monitoring alarm, etc.

6. Control water pressure to avoid water hammer effects

Generally speaking, the working water pressure of a pure water machine is generally between 0.10 and 0.40MPa. Due to factors such as office floors, if the water pressure is too high, it is easy to cause water hammer effects, damage internal parts, or lead to water leakage. If the water pressure is too low, it will not meet the water outlet standard, affecting the normal operation of the equipment. Therefore, in order to extend the service life of the equipment, it is recommended that users measure the water pressure at the place of use and install a pressure reducing valve or booster pump according to the situation.

Everyone must pay attention to the above points in their daily use and operation of equipment. If corresponding protective or adaptive measures are not taken for the equipment, it will lead to reduced performance, shortened service life, and even lead to accidents. Proper daily operation and maintenance not only reduce the occurrence of faults, but also prevent them from happening before they occur; It has also improved work efficiency and extended the service life of the equipment.
