In the oil – supply system of the turbine governor’s oil – source device in hydraulic generating sets, WSMJ series special screw pumps play a vital role. Built on our company’s mature triple screw pump tech, these pumps are crafted for medium – and high – pressure uses. We design and produce them strictly per the GB/T10886 – 2002 triple – screw pump standard, ensuring top – notch quality and reliable performance.
Unique Structure, Outstanding Performance
1. Smooth Conveyance, Low – noise & Stable
WSMJ series pumps have a special helical profile. As screws rotate, moving sealed chambers act as precise channels, smoothly sucking in liquid at the inlet and axially conveying it to the outlet without pulsation. This unique mode ensures smooth operation, cuts vibration and impact from liquid flow, reducing noise and keeping flow rate stable. It reliably supplies oil to the turbine governor’s oil – source device.
2. Axial Balance, Durable
Main and driven screws use an advanced axial – balance design, rotating driven by hydraulic pressure. During operation, they stay balanced, minimizing deformation risk from uneven stress. Also, the screws don’t touch while running, avoiding wear. This extends screw lifespan and ensures long – term stable pump operation. Plus, the pump has strong self – priming, quickly sucking in tank liquid on startup, skipping priming hassle and boosting efficiency.
3. Submerged Structure, Optimized Layout
The pump’s suction port is inside the oil tank, with discharge above. The pump body connects firmly to the tank, forming a submerged structure. This design lets the pump suck liquid directly from the tank, shortening and simplifying the suction pipeline, reducing cavitation risk. It also optimizes equipment layout, making it more compact, taking less space, and easing installation and maintenance in the limited space of the hydraulic generating set.
Wide Performance Range, Meeting Diverse Needs
1. Flow Rate
The WSMJ series pumps have a flow – rate range of 10 – 50 cubic meters. This wide range meets the oil – supply flow – rate needs of turbine governor oil – source devices in hydraulic generating sets of all scales. Whether for small – scale hydropower or large – scale water projects, the pump can supply a well – matched flow rate.
2. Rotational Speed
The pump’s rotational speed ranges from 2900 – 1450 revolutions. You can adjust it flexibly based on actual working conditions to precisely control flow rate and pressure. A higher speed suits rapid – oil – supply scenarios, while a lower one is better for higher – stability, lower – flow – rate needs.
3. Pressure
The pump’s pressure range is 2.5 – 6.3 Mpa, in the medium – to – high – pressure category. It provides enough pressure for the turbine governor’s oil – source device in the complex hydraulic – generating – set environment. This ensures smooth oil transport to key parts, guaranteeing precise governor control and stable operation.
With its unique design, great performance, and wide – ranging capabilities, the WSMJ series special screw pumps are the ideal choice for the turbine governor’s oil – supply system in hydraulic generating sets, powerfully supporting the efficient and stable operation of the hydropower industry.
