Single drive hydraulic turbine pump
By making use of the remaining energy to realize the energy conversion to drive ZHT series single drive hydraulic turbine pump which loads recoverable energy with high recovery efficiency. The turbine pump and the load are direct driven without overdrive clutch and full power motor, which is more reliable and with small occupied room, with the features of low investment and maintenance costs, and the DCS control is simple and reliable.
■ Flow rate：Q= 420~2600 m³/h
■ Total Head：H=120~640 m
■ Speed：n=2970 r/min
■ Temperature：T=-20~250 ℃
■ Products comply with API610 standards, shaft seal system meets the API682 standard.
■ With thickened heavy shaft design, strong shaft and bearing loading ability, long service life.
■ With high turbine efficiency and full energy recovery.
■ The turbine and the load are direct drive, with small occupied area and low investment and maintenance costs.
■ DCS control is simple and reliable.
■ The turbine can be safe operation when it gets over 10% of the rated speed, and the system can fully recover the surplus energy.
■ There are many flushing options for mechanical seal and selecting the domestic famous manufacturers of mechanical seal with reliable sealing and long service life.
■ Turbine is stable operation with low noise.
■ ZHT hydraulic turbine is divided into three types:
(1) ZHT single stage single suction cantilever center support type OH2 structure;
(2) ZHT (S) single stage double suction type BB2 structure;
(3) ZHT (D) multistage single suction self balance center support type BB4 structure.
■ All turbines are upper-inlet and upper-outlet.
■ All turbines are center support suitable for high temperature medium.
■ All bearings adopt water cooling structure, to improve the service life of bearings.
