Product type-description:
There are two types of structures, one with a 1.5-meter pump length and fittings, and the other with the longest pump length of 7 meters.
the longest pump length of 7 meters.
The FYL type liquid pump is generally used in clean or slightly corrosive, chemically reactive, or containing small amounts of solid particles, and other similar applications. The immersion length of the pump into the container is generally not more than 7 meters, and the flow rate is generally less than 1000m3/h. If the flow rate exceeds this range, the VS1 type should be used instead.
The FYL type of submerged pump has an outlet diameter of generally less than 300mm . The pump speed is usually 1450r/min or 980r/min, the flow Q: ~ 1550m3/h, the head H: ~ 50m, and the bearing box is equipped with 2 matched angular contact ball bearings and 1 cylindrical roller bearing. The sealing form is a grease seal structure or a grease seal combined with a magnetic oil seal. There are two types of impellers: closed and open, so it can transport liquids containing a small amount of solid particles.
with a 1.5-meter pump length and fittings
VS5 strcture:
The pump is a vertical cantilever (suspended) submerged centrifugal pump, with the pump body and impeller immersed in the medium. It is suitable for the conveying of industrial wastewater, sewage, slurries, corrosive and liquid containing solid particles.
The temperature of the medium to be conveyed is below 100ºC. If higher temperature liquid is to be conveyed, special materials should be used for manufacturing.
Performance range: flow rate 10~380m3/h, head 10~50m.
Suspension length (distance from the base plate to the centerline of the impeller outlet): 0.5~1.5m.
Pump Structure Features:
The main components are: pump body, impeller, front cover, shaft, support pipe, discharge pipe assembly, base plate, bearing housing assembly, filter, packing seat, motor, impeller nut, etc.
Rotation direction of the pump: The impeller rotates in a clockwise direction when viewed from the drive end.
Pump speed: ≤ 1450 r/min. Low-speed pumps operate more stably and reliably.
1. The whole pump is designed in a suspended arm structure, and the impeller is designed in a semi-open or full-open style, which can transport liquids containing certain solid particles.The pump usually comes with an inlet short pipe and a filter net.
2. The bearing housing assembly has good overall rigidity, a long bearing span, and uses a pair of angular contact type ball thrust bearings (7000 series) and short cylindrical bearings to support the radial and axial loads. The angular contact type ball thrust bearings are installed back-to-back.
3. The pump shaft diameter is thick, and the operation is stable and reliable.
4. The impeller nut has an anti-loosening device, which can effectively prevent and eliminate the falling off of the impeller during the pump operation. SDPump®
5. Because the pump is a suspended (arm) structure, therefore, a support device with no sliding bearings is used behind the impeller. Of course, sliding bearings can be installed if necessary or required by special working conditions.
6. The pump body, pump cover, and impeller are usually made of wear-resistant materials, but they can also be selected reasonably according to the user's requirements or the working conditions of the medium.
Structural Design Features and Advantages:
One, Structural Features:
1. The FYL type liquid pump adopts an extended bearing housing structure, which has two matched thrust ball bearings and one cylindrical bearing inside the bearing housing, which bear radial and axial loads respectively. The pump has a low speed and a thick pump shaft, which makes the structure stable and has a strong bearing capacity. The sealing form is oil seal structure or oil seal plus magnetic oil seal combination. There are two types of impellers: closed and semi-open. The normal type is the semi-open impeller.
2. The pump is divided into two structural forms in total: The first type of pump is a single pipe and a single shaft configuration, with no support sleeve at the lower part, which is a cantilevered type. It is mainly used for conveying slurries containing solid particles, whose solid content is generally not more than 20%. The wear-resistant materials or corrosion-resistant materials are usually used for the wear-resistant parts. Under special circumstances, the lower part is equipped with a support structure, such as Dalian Hengli Petrochemical, where the working conditions are harsh, and the solid content is as high as 30%. At the same time, an external flush water is used to flush the support position. The semi-open impeller (a few use the full-open impeller). The second type of pump is composed of multiple pipes and multiple shafts, with a support structure at the lower part, which is mainly used for conveying slurries containing a small amount of solid particles or corrosive liquids. The intermediate support positions are all lubricated by external flush or self-flush. When viewed from the driving end, the pump rotates counterclockwise.
3. The bearing housing form is divided into two types: The first type is that the entire bearing housing position is located on the upper part of the base plate, and the second type is that half of the bearing housing position is located on the upper part of the base plate and the other half is located on the lower part of the base plate. Under normal circumstances, the first type is used, and if the second type is used, the extension length can be slightly increased, but there is a limit to the liquid level height to prevent liquid from entering the bearing housing
