1.每一個(Gè)90度彎(Wān)頭或90度三(Sān)通損失約1米揚程。
It will lose 1 meter‘s lift when you add a 90 ° elbow or three-way pipe in the pipeline.
2.每20米管路長度損(Sǔn)失約[Yuē]1米揚程。
It will lose 1 meter’s lift when the pipeline exceeds 20 meters.
3.如果出水(Shuǐ)管路直徑有過[Guò]渡(Dù)（縮徑）或分流（三通等），為▿了▿減[Jiǎn]●少●流體能量在管路中[Zhōng]的[De]損失，請使過渡段（縮徑）或◆分◆流（三通等）盡量遠離泵的出口，◇以◇接近噴嘴處(Chù)為最好。
If there is a reducing bend or a three-way in the pipeline. In order to reduce the energy loss, make the reducing bend or the three-way as far away from the pump, close to the nozzle for the best.
4.吉林吉特(Tè)建議:單級泵能滿足要[Yào]求⋄時⋄,盡量不選擇多級泵.因為: ①多(Duō)級泵對(Duì)介質清潔⋄度⋄要⋄求⋄高[Gāo],容易堵塞. ②多級泵流道變長,對介質熱輸入高,冷卻效果受影響.③多級泵有機械◆密◆封,不耐幹轉和污[Wū]物,屬于易損[Sǔn]件。
JL-JET suggestions: Try not to choose the multi-stages pump if the single-stage pump can meet the requirements. Because the multi-stages pump: Ⅰ.It is easily blocked by impurity. Ⅱ. The heat input is high. Ⅲ. The mechanical seal is the wearing part. It is not adapt dry running.
5.如果選用(Yòng)多級泵,同軸[Zhóu]泵要優先于斷軸泵. 因⋄為⋄(Wéi)電機水泵同(Tóng)軸結構,避免了聯軸器産生故障的可能.另外,◇同◇[Tóng]軸泵的液◊上◊部(Bù)分尺(Chǐ)寸占用空間小. 但是液下尺寸要求較長(Zhǎng)時,斷軸泵要優于同(Tóng)軸[Zhóu]結構。
The coaxial pump takes precedence over the separate shaft pump. Because the coaxial structure, avoiding the coupling failure. In addition, the coaxial pump’s motor part takes smaller occupation than separate structure. But when there is long under water size requirement, the separate structure is better than the coaxial pump.
6.如選用PJT-XXA，LXB-XXA和[Hé]DJB-XXA系列型号時，遇有管路較▲長▲且泵進水口▿高▿于液面設計時，請您在泵的進(Jìn)水端加裝逆止閥,使停機後泵腔及管(Guǎn)路中介質▿不▿(Bú)倒灌回水箱,以利于[Yú]再開機時介質迅速到達工作(Zuò)◇點◇。
If you chose JL-JET’s model such as PJT-XXA，LXB-XXA and DJB-XXA, please add a cut-off valve at the inlet part of pipeline.
7.⋄在⋄選泵[Bèng]用于粘度[Dù]較高的介質時，建議⋄您⋄選擇功率揚[Yáng]程時選高一個等級的型号或特◇殊◇(Shū)訂貨。
For high viscosity media, JL-JET advice you to choose a higher level power model.
8.如遇同一台機床使用兩台泵（或排屑機），電器設計務必單獨控[Kòng]制，避免單台▽使▽(Shǐ)用時◆另◆一台(Tái)空運行。
If a machine uses two pumps, electrical control system must be designed individually. This is to avoid one pump working another idling.
9.吉林吉特産品[Pǐn]為220V/380V 50Hz三相[Xiàng]雙電壓，默◇認◇電機出(Chū)廠接線為Y接380V, 如有特殊要求，請(Qǐng)提前說▾明▾ Our default connection model is "Y"380V and 50Hz, if there are special requirements, please notify JL-JET.
10.吉∆林∆吉特産品标準配(Pèi)用的電機的防護等◈級◈(Jí)為IP44. 如有特殊要求，請提前說明[Míng]。
JL-JET’s default protection level is IP44. if there are special requirements, please notify JL-JET.
11.吉林吉特(Tè)▿可▿承接特殊頻(Pín)率、特殊電壓[Yā]及[Jí]三防等特殊要求訂貨。
JL-JET can accept orders of special frequency and voltage
12.為了保護環(Huán)境,節能減排,⋄同⋄[Tóng]時節約采購▿成▿(Chéng)本. 吉[Jí]林吉特建議您, 請盡量選擇[Zé]低(Dī)功率電機。
For the purpose of environment protection, JL-JET suggests you to choose low power motors.
13.常用◇揚◇程單◇位◇(Wèi)換算 （吉林吉特設計依▽據▽的[De]揚●程●單位為"米"）。
Common units transfer of lift. JL-JET’s basic unit is "H".
14.常用流量單位換[Huàn]算 （吉林吉特設計依據的流量單∇位∇為"∇升∇/分"）。
Common units transfer of flow. JL-JET’s basic unit is "L/min"
