How much do you know about the daily, monthly and annual maintenance of purified water equipment?

[Pharmaceutical Network Technical Article] Purified water can be used as raw material production, separation and purification, finished product production, cleaning and washing water, and is widely used in biopharmaceutical, medical equipment and other industries
.

In recent years, with the rapid development of the pharmaceutical industry and stricter quality standards, in order to meet the corresponding water quality standards in the pharmaceutical industry, pharmaceutical factories usually need to use purified water equipment to prepare purified water, thereby improving the production water environment and enhancing competitiveness
.

It is worth mentioning that after the purified water equipment is put into use, users should operate the equipment scientifically according to the specifications, and also need to do maintenance work to ensure the continuous and stable operation of the system and the water production standards, and prolong the service life of the equipment
.

It is understood that, according to the different maintenance cycles, the maintenance of purified water equipment can be divided into daily maintenance, monthly maintenance and annual maintenance.
Let’s take a look at it together
.

Routine maintenance The daily maintenance of purified water equipment mainly includes inspection before starting, after starting and after stopping, each of which is very important.
In order to ensure the long-term stability of the system and the safety of water production, enterprises should pay more attention
.

For example, before starting the machine, it is necessary to check whether the power supply is normal, whether the compressed air supply pressure, the raw water supply pressure, etc.
are within the normal range, whether the equipment valves are in normal state, whether there is leakage in the air pipes and water pipes, and whether the clamps and bolts are fastened.
etc.

_
 　　After starting the machine, it is necessary to confirm whether the main control program is running normally, whether the water pump, the water pressure of each operating pressure gauge, etc.
, and whether the water quality inspection of the produced water meets the requirements, and whether there are abnormal noises in the pipes, pumps, and valves
.

 　　If the purified water is shut down, it is necessary to clean the equipment, confirm that the automatic valve parts return to the initial state, drain the residual water in the storage tank and pipeline, and ensure that the main power supply, gas source, water source and steam valve are all closed
.

 　　Monthly maintenance The main contents of monthly maintenance of purified water equipment include three aspects
.

First, regularly clean salt tanks, medicine boxes and water storage tanks.
The industry points out that, especially for purified water tanks, enterprises should clean and disinfect after monthly or quarterly shutdowns to prevent microbial growth; second, regularly replace purified water equipment Consumables such as precision filter PP filter element, respirator filter element, etc.
in the middle, so as not to affect the effluent quality; Third, regularly check or test the instrument, if the instrument is found to be damaged or the deviation exceeds the standard, it should be replaced in time
.

 　　Annual maintenance The annual maintenance of purified water equipment mainly includes four aspects
.

First, replace the consumables of the multimedia filter, softener, and activated carbon filter; second, check the circuit protection cover of the electric control part, check and tighten the wiring terminals, check the waterproof sealing strip of the electric box, replace the filter cotton of the electric box fan, and Dust removal inside the box, etc.
; thirdly, dismantle and clean the valve diaphragm, quick-clamp pad, steam Y-type filter, and steam trap; fourthly, check and tighten the mechanical parts such as valve screws, handles, and pump couplings
.

 　　According to the industry, the good working performance of purified water equipment is not only related to the quality of the equipment itself, but also the operation and maintenance of the equipment.
Therefore, enterprises are reminded that they need to do daily, monthly and annual maintenance.
Work plan, and strictly follow relevant regulations, so as to continuously obtain high-quality purified water and ensure the healthy and stable operation of pharmaceutical production
