1. It is required that the parallel tolerance between the outlet water tank of multi-media filter and the filter plate shall not be greater than 2mm.

2、濾板的水平度和粗糙度小于1.5毫米。對(duì)于濾板的結(jié)構(gòu)，整體加工很好。當(dāng)圓筒直徑較大，或受到原材料、運(yùn)輸?shù)鹊南拗茣r(shí)。它也可以由兩個(gè)閥門拼接而成。

2. The levelness and roughness of the filter plate are less than 1.5mm. For the structure of the filter plate, the overall processing is very good. When the diameter of the cylinder is large or limited by raw materials, transportation, etc. It can also be assembled from two valves.

3、濾板與筒體連接部位的合理處理對(duì)空氣反沖洗尤為重要。

3. The reasonable treatment of the connection between filter plate and cylinder is very important for air backwash.

4、為了消除濾板與筒體之間因加工多介質(zhì)過濾器和軋制筒體時(shí)的誤差而產(chǎn)生的徑向間隙，弧形環(huán)板一般是分段焊接的。接觸零件需要采用全焊。

4. In order to eliminate the radial gap between the filter plate and the cylinder due to the error in processing the multi-media filter and rolling the cylinder, the arc-shaped ring plate is generally welded in sections. Contact parts require full welding.]

5、管和濾板的徑向間隙處理方法同上。備注:以上措施保證多介質(zhì)過濾器過濾和反沖洗只能通過過濾帽或排氣管縫隙連通。同時(shí)，保證了反沖洗和過濾通道的分布均勻性。

5. The treatment method of radial clearance between central tube and filter plate is the same as above. Remarks: the above measures ensure that the filtration and backwashing of the multi-media filter can only be connected through the gap of the filter cap or exhaust pipe. At the same time, the distribution uniformity of backwashing and filtering channels is ensured.

6、過濾板上加工的通孔的徑向誤差為1.5毫米。增加過濾帽導(dǎo)桿與過濾板通孔的配合尺寸不利于過濾帽的安裝或固定。加工通孔需要使用機(jī)械設(shè)備。

6. The radial error of the through-hole machined on the filter plate is 1.5mm. Increasing the matching size of filter cap guide rod and filter plate through-hole is not conducive to the installation or fixation of filter cap. Mechanical equipment is required to process through holes.

7、多介質(zhì)過濾器過濾帽材料為尼龍，其次為ABS。由于在上部添加了過濾材料，過濾帽上的擠壓載荷非常高，需要高強(qiáng)度以避免變形。過濾器蓋和過濾板之間的接觸面(上下表面)應(yīng)增加彈性橡膠墊。

7. The filter cap material of multi-media filter is nylon, followed by ABS. Due to the addition of filter material in the upper part, the extrusion load on the filter cap is very high and high strength is required to avoid deformation. The contact surface (upper and lower surfaces) between the filter cover and the filter plate should be added with elastic rubber pads.
