Direct pulling type speed hydraulic coupling
The self-developed hydraulic coupling has the features of high speed, high power, sensitive speed regulation and cost efficiency, and has received the national patent (The patent name: Direct pulling type speed regulation device of hydraulic coupling, and the patent number: ZL2008 2 0122800.0).
●Product Model and Performance Parameter
1. It has reasonable structure, advanced performance and high reliability, and can meet the requirements of long-term continuous operation conditions in metallurgy, building materials and power generation industries;
2. The motor can be started at no load, and it is not necessary to select a prime mover such as a motor with a large power head capacity, and the fluctuation of the grid load can be reduced;
3. Speed regulating fluid coupling has overload protection performance;
4. Isolation of vibration to slow down the impact;
5. No direct mechanical contact between transmission parts and long service life;
6. High transmission efficiency at rated load;
7. With hydraulic control speed control device and two half shafts, it is easy to realize long-distance automatic operation.
● Technology Feature
It adopts the unitary herringbone design, and its pulse-on is steady without impact. It can complete non-grade speed-change (25% to 100%) to satisfy the sliding pressure motion produced by the water pump that adapts to the boiler.
●Scope of Application
It is used for speed regulation motion of water feed pump unit and fan in generator unit and other high-power and high-speed centrifugal machinery, as well as the pulse-on motion of the boiler water feed pump unit of the 1000MW-capacity unit.
