LDTV(VS1) vertical suspended single shell pump

>VS1(LDTV)

LDTV series vertical suspended single-casing pumps are of API610 (IS013709) VS1 structure, and the design standards comply with API610 11 “Centrifugal Pumps for Petroleum, Petrochemical and Natural Gas Industries” and API682 4 “Centrifugal Pumps and Rotary Pump Shaft Seal Systems” , a single-casing, radially split, center-discharge, vertical suspension centrifugal pump.

This series of pumps are wet pit pumps. The rolling bearings are lubricated with thin oil, and the submerged sliding bearings adopt a multi-point support structure. At the same time, careful consideration and design have been carried out in terms of support, cooling, installation and maintenance structures, and can be equipped with various auxiliary and Monitoring system makes this series of products highly safe and reliable. The sealing cavity size complies with API682 requirements, and various types of mechanical seals can be configured according to different working conditions.

>SERVICES

It is mainly used in petrochemical industry, coal chemical industry, cryogenic engineering, nuclear power and other fields, suitable for transporting various clean media or media containing trace particles.

Structure Feature

>Impeller: The impeller adopts an efficient hydraulic model to ensure the hydraulic performance of the pump. Each stage of the impeller is individually positioned with a snap ring to improve positioning accuracy.

> Bearing components: Angular contact ball bearings installed in pairs are used as thrust bearings to withstand the residual axial force at the moment of starting and during operation; the bearing lubrication method is thin oil lubrication, and a fan or cooling coil design is used to reduce Bearing temperature rise, the bearing parts are equipped with standard temperature measurement and vibration measurement holes, which can monitor the operating status of the unit at all times to ensure the smooth operation of the pump.

>Intermediate support: It adopts multi-point support design, and the support span between sliding bearings meets the requirements of API 610 standard. At the same time, sliding bearings are installed before and after the first-stage impeller, at the suction inlet of the secondary impeller, and between the last-stage impeller and the outlet section to ensure that the pump rotor has sufficient support stiffness. The bushing material can be selected according to different working conditions, such as Antimony-impregnated graphite, composite materials, etc.

>Mechanical seal: The sealing system complies with API682 4th edition “Centrifugal Pump and Rotary Pump Sealing System” and China Petroleum & Chemical Industry material procurement standard requirements, and can be configured with various forms of sealing, flushing, and cooling solutions.

>Exit section: The exit section adopts assembly welding structure.

> Balance pipeline: The balance pipeline is connected from the balance chamber to the outlet of the first-stage impeller to ensure that the balance chamber has at least the head pressure of the first-stage impeller to avoid vaporization when transporting light hydrocarbon media.
