1. Temperature: during the operation of multi-media filter in the process of water quality treatment, if the temperature is lower and lower, the viscosity of raw water will become larger and larger, and the filtration speed of the equipment will slow down, thus making its water production efficiency lower. In the case of making the same amount of water, the time spent will increase with the decrease of temperature. The viscosity of liquid is an exponential function of temperature, which decreases rapidly with the increase of temperature. To a certain extent, heating is a simple and effective measure to reduce viscosity, and also an effective measure to speed up the production efficiency of ultra pure water.

2、水壓：多介質(zhì)過濾器水質(zhì)的過濾工作需要借助壓力來完成，只有在合適的壓力下才能對(duì)水起到好的過濾效果。壓力如果過小，水產(chǎn)量就會(huì)變小，設(shè)備的制水效率降低。壓力過大，也不利于多介質(zhì)過濾器的工作，長(zhǎng)期壓力過大，會(huì)加快多介質(zhì)過濾器的老化，也會(huì)加劇濾料的損耗，給使用增加了成本。

2. Water pressure: the water quality filtration of multi-media filter needs to be completed with the help of pressure. Only under the appropriate pressure can the water have a good filtering effect. If the pressure is too small, the water yield will be reduced and the water production efficiency of the equipment will be reduced. If the pressure is too high, it is not conducive to the work of the multi-media filter. If the pressure is too high for a long time, the aging of the multi-media filter will be accelerated, and the loss of the filter material will be increased, which will increase the cost of use.

3、雜質(zhì)的含量和種類：多介質(zhì)過濾器使用的主要目的就是為了去除水中的各種雜質(zhì)，但是各地區(qū)水中的雜質(zhì)種類不同，使用多介質(zhì)過濾器沒能很好的進(jìn)行去除，這時(shí)就需要添加一定的預(yù)處理，先將水中的大顆粒物質(zhì)沉淀掉。

3. Content and type of impurities: the main purpose of multi-media filter is to remove all kinds of impurities in water. However, the types of impurities in water are different in different areas, and the use of multi-media filter can not remove them well. At this time, it is necessary to add certain pretreatment to precipitate the large particles in the water.

多介質(zhì)過濾器的維護(hù)與保養(yǎng)需要對(duì)設(shè)備本身來進(jìn)行要求，明確多介質(zhì)過濾器維護(hù)保養(yǎng)的目的，可以及時(shí)的處理設(shè)備在運(yùn)行過程中由于技術(shù)狀態(tài)的變化而引起的大量的問題，可以隨時(shí)的改善設(shè)備的技術(shù)狀況，保證正常的運(yùn)行，延長(zhǎng)多介質(zhì)過濾器的使用壽命。

The maintenance and maintenance of the multi-media filter requires the equipment itself. The purpose of the maintenance of the multi-media filter is clear. It can timely deal with a large number of problems caused by the change of technical status in the operation process of the equipment. It can improve the technical status of the equipment at any time, ensure the normal operation, and extend the service life of the multi-media filter.

多介質(zhì)過濾器一旦出現(xiàn)了損壞通常會(huì)導(dǎo)致正常的運(yùn)行失敗，所以需要及時(shí)的對(duì)設(shè)備進(jìn)行定期的檢查、保養(yǎng)與維護(hù)。使用一定的工時(shí)用于維護(hù)保養(yǎng)。對(duì)設(shè)備中的各種部件進(jìn)行檢修，關(guān)注濾料的情況。

Once the multi-media filter is damaged, it usually leads to normal operation failure, so it is necessary to timely carry out regular inspection, maintenance and maintenance of the equipment. Use certain working hours for maintenance. Overhaul various parts of the equipment and pay attention to the condition of filter materials.

主要的部件應(yīng)設(shè)?？ㄓ涗洰a(chǎn)地、價(jià)格、運(yùn)行狀況、維修次數(shù)、保養(yǎng)人等。所有設(shè)備應(yīng)有足夠的零配件，在寒冷地區(qū)冬季使用時(shí)，尤其需要注意室外管道、閘門、水泵等設(shè)備的防凍保溫工作。

Special card should be set for main parts to record the place of origin, price, operation status, repair times, maintenance personnel, etc. All equipment should be equipped with enough spare parts. When it is used in winter in cold areas, special attention should be paid to the anti freezing and thermal insulation work of outdoor pipelines, gates, pumps and other equipment.
