Product Description

Product type-description:

The vertical submerged pump (suspended, single-shell, long-shaft driven oil sump pump) is called the VS4 pump.
The VS4 submerged pump is generally used in clean, corrosive, and chemical fluid transfer applications, and its immersion length in the container is generally not more than 7 meters. Our company's pump models include SLY, FYL, and SDY.
VS4

The outlet diameter of SLY type pump is generally less than 200mm, and the extension length is generally 5.5m Within. Two speeds: 2900r/min and 1450r/min. Flow Q: ~ 500m3/h,Lift H: ~ 120m, closed impeller structure, bearing box for 2 pairs of thrust ball bearings ,Bearing radial and axial forces, sealing forms are: mechanical seal, packing seal, V-ring Seal it. On this basis, SLG type high temperature liquid pump is derived, with both support pipe and outlet pipe .With thermal insulation jacket structure, which is characterized by high temperature resistance, easy to transport crystalline liquid,Shaft seals are generally packing seals.

Flushing mode:

A clean liquid is introduced under the SLY pump to flush the pump, one is to flush the bushing inside the pump cover, the other is to flush the bushing inside the plain bearing, Play the role of lubrication, washing, cooling bushing. If not connected to the washing liquid, the pump bushing, especially exposed to the upper liquid bearing will be damaged due to dry grinding Bad, so flushing is essential. For different media, there are two ways to choose.

(1) Self-washing: When the pumping medium is a clean medium,

this way is used for washing. Lead a line from the pump outlet

flange or liquid outlet pipe to make the flushing liquid flow

Pump cover and each sliding bearing body.

(2) External flushing: When the pumping medium is an embedded granular medium, this method is used for flushing. Lead a pipe from the outside and introduce a clean flushing solution to flush Pump cover and each plain bearing body. External clean flushing liquid, flow rate is 0.5~0.8m3/h, pressure is 0.15~0.2MPa.

 

1.With bearing seat, easy to adjust axial position of the rotor;grease lubricated bearing structure;this structure is simple, safe and reliable.
2.External flushing pipe,external clean medium is used to flush sliding bearing,which makes bearings run in good lubrication condition.
3.Seal chamber does not contact with the pump.Packing seal,mechanical seal can be selected according to user requirements to choose in order to prevent volatile gas of the medium spilling over.
4.Multi-point supporting sliding bearing structure;the bearing spacing conforms to the API610 requirements.
5.Discharge pipe is VS4 structure;no pressure medium between support column and the seal.High hydraulic efficiency .
6.Thread,sleeve spindle structure: high coaxial degree, accurate positioning, reliable transmission torque.
7.Self-flushing line, pumping medium from pump outlet flushes sliding bearing, pumping medium is required to be clean and has a certain lubricity to ensure bearing lubrication.
8.Pump body is designed as 1.6~2.5MPa, the inlet can be connected to the filter, the pump to filter media.The inlet can be connected with filter net, and the pumping medium is filtered.
