3G螺杆泵安装要求Installation requi rements of therr screw pump type 3G

6.1安装前应检查螺杆泵 的油封是否良好,并检查泵在运输中是否损坏,可用手转动联轴器是否有卡劲现象,如有则应拆泵进行清洗,修理和校正。

Bethre installationthe oil seal of the pump should be checked. To see if it is in orderand inspect whether the pump is damaged in transit. Turn the coupling with hand to see if it is blockedif sothe pump should be dismantled for cleaningrepair and adjustments.

6.2安装螺杆泵 的进油和排油管道时,其管径不得小于泵的进油和排油口口径,进油管道不得过长,弯头不得过多,否则将影响泵的工作状态。

When installing oil inlet and oil discharge Pipingthe diameters of pipes which should not be smaller than the oil inlet and oil outlet of the pump respectively. The oil inlet piping should not be too longshould not have too many bendsotherwise the function of the pump will be affected.

6.3当有两台以上的螺杆泵 安装在同一条主管线上,为便于泵的启动,在近泵的排油管上必须安装逆止阀。

In case two sets or more pumps are installed on one main line. Value must be installed close to the oil discharge pipe of the pump so as to facilitate starting of the pump.

6.4对于在较高温度(60以上)下输送粘度大的油类(如:重油)的备用泵,必须是热备用泵,否则泵在低温下启动会电机过载或泵损坏,(建议在靠进泵的排油管上的逆止阀旁,并联安装一个小回流阀,对备用阀可微启回流阀,使螺杆泵 缓慢逆转,其你转速≤100/分,使部分热油经常流过泵内,达到泵热备用目的)。

When conveying oil of comparative high viscositysuch asheavy oilunder higher temperatureabove 60℃)by a spare pumpsthe spare pump must be heated. Otherwise starting of pump under low temperature will cause overload of motor or damage pipe to the pump It is suggested that a small return may be slingtly opened to spare pump .causing slow

reversal of the pump at a speed of 100r.p.mthus allowing part of the hot oil frequently flow

5

though the pump ready for use.

6.5输送介质内含有机械杂质,将严重影响螺杆泵 的运转和降低使用寿命,因此在泵安装前,必须仔细清除进油管内的焊渣,沙粒等杂质,并应在进油管道靠近泵处安装滤器,滤器网孔大小,可根据工作情况及杂质粘度确定,(一半可用40-80目网),过滤面积一半不得小于进油管横截面积的20倍。

Any mechanical foreign matters containing in the conveyed medium will affect the operation and drop life of application of the pumpthere forethe inner part of the oil inlet piping must be carefully and thoroughly cleaned of the solder slagsand and other foreign matters before installation of the pump Besidesa filter should be installed on the oil inlet piping at a point close

to the pump the mesh of the filtering screen maybe determined According to the working condition and the viscosity Of the medinm generally 40~80 mesh may be used. The filtered area should in the main not be smaller than 20 tines the area of cross section other oil inlet pipe.

6.6尽量在螺杆泵 进油和排油口处的螺纹孔上连接压力表和真空表。以便于观察泵的运转状态。

As can as possible to fit a pressure gauge and a vacuum gauge on the threaded hole of the oil inlet and oil outlet to facilitate observation of the operation condition of the pump.
