信龍濾清器產(chǎn)品特點：
1、分高壓段用、中壓段用、回油段用和吸油段用
2、分高中低精度等級。2—5um為高精度，10—15um為中等精度，15—25um為低精度。
3、為壓縮濾芯成品外形尺寸，增大過濾面積，一般濾層部分折成波紋狀，液壓濾芯打褶高度一般在20㎜以下
4、液壓濾芯承受壓差一般在0.35—0.4mpa，但個別特殊濾芯，要求承受高壓差，最高要求承受32mpa，甚至42mpa等同系統(tǒng)壓力。
5、最高承受溫度，有的要求達(dá)到135℃
產(chǎn)品要求：
1、強度要求，制作完整度要求、承受壓差、承受安裝外力、承受壓差交變載荷
2、通油的順暢度要求，流量阻力特性
3、耐一定的高溫，與工作介質(zhì)相容
4、濾層纖維不能位移和脫落
5、成承載較多的污物
6、高空及寒冷地區(qū)使用正常
7、耐疲勞，交變流量下的疲勞強度
8、濾芯本身清潔度要達(dá)標(biāo)
測試標(biāo)準(zhǔn)：
（1）iso2942液壓傳動-濾芯-結(jié)構(gòu)完整性的測定
（2）iso16889液壓傳動-過濾器-測定過濾特性的多次通過法
（3）iso3968液壓傳動-過濾器-壓降流量特性的測定
（4）iso3724液壓傳動-濾芯-流動疲勞特性的測定
（5）iso3723液壓傳動-濾芯-軸向載荷試驗方法
（6）iso2943液壓傳動-濾芯-材料與液體相容性的驗證
（7）iso2941液壓傳動-濾芯-抗破裂性的驗證
液壓濾芯的更換時間：
液壓挖掘機一般在運轉(zhuǎn)2000h以后就需要更換液壓油，否則將使系統(tǒng)污染，造成系統(tǒng)故障。據(jù)統(tǒng)計，液壓系統(tǒng)的故障中90%左右是由于系統(tǒng)污染所造成的。
在檢查油品的顏色、黏度、氣味的基礎(chǔ)上，還要檢測機油壓力、空氣濕度。若工作在海拔較高、溫度較低的環(huán)境，還必須密切注意發(fā)動機機油里含炭量、膠質(zhì)物(烯烴)和硫化物，以及柴油里的雜質(zhì)、石蠟和水分的含量。
特殊情況，若機械使用低等級柴油(柴油中含硫量0.5﹪～1.0﹪)，應(yīng)每隔150h更換一次柴濾、機濾;含硫量在1.0﹪以上應(yīng)每隔60h更換一次柴濾、機濾。使用破碎器、振動夯等對液壓系統(tǒng)負(fù)荷較大的設(shè)備，液壓回油濾芯、先導(dǎo)濾芯和呼吸器濾芯的更換時間為每隔100h更換一次。
