三螺杆泵水压试验Hydrostatic test 我厂在成品泵完成后，需要进行水压试验，在进口法兰处装入端盖，对于45B的三螺杆泵，通入0.6MPa的大气压，把整个成品泵沉入水中，观察是否有气泡。得到泵体、后盖、密封压盖等零部件处是否因为铸件沙眼、密封不够、螺丝松牙等原因漏气。I plant after completion of the finished product pump, water pressure test is required, at the inlet flange at the load end cover, three screw pump for 45 b, ventilation with atmospheric pressure of 0.6 MPa, the entire finished product pump submerged in the water, observe whether there is a bubble.Get the pump body, back cover, gland and other parts to inquire whether because the casting trachoma, seal is not enough, due to reasons such as flat screw loose teeth.
三螺杆泵选泵要点Optional pump points
①首先应根据油品的粘度选择适当的泵转速，以保证泵的粘度能满足用户的实际吸入条件。the first select the appropriate pump speed should be based on the viscosity of the product, to ensure that the viscosity of the pump can satisfy the user's actual suction conditions.
②介质粘度V>760 /s，请与我厂联系，我厂帮助用户选泵。 medium viscosity V > 760 / s, please contact our factory, our factory to help users choose the pump.
③从性能表中选定泵的规格及相应粘度下的压力流量后，可以查到泵的配套电机功率。Selected in the table (3) from the performance of the specifications of the pump and the corresponding viscosity under pressure flow, you can check the pump motor power.
④样本安装尺寸均为卧式安装尺寸，若需其余形式安装尺寸请与我厂联系。 the installation size of samples for horizontal installation size, if you need the rest of the installation dimensions form please contact with our factory.
 ⑤我厂可根据客户的实际需要设计特殊尺寸。Our factory can design according to customer's actual needs special size.
⑥三螺杆泵的进口需加装过滤器，过滤器过流面积应为泵进口截面积的7～13倍，过滤目数应为：轻油80～100，润滑油60～80目，重油40目。 pump imports to be equipped with filter, filter over-current area shall be the pump inlet area of 7 ~ 13 times, filter mesh should be followed: light oil 80 ~ 100, 60 ~ 80 mesh of lubricating oil, heavy oil 40 mesh.
