What are the parameters of the HL300 WJ 71 turbine

The parameters of HL300-WJ-71 turbine are: HL--Francis, runner code--300, WJ--horizontal shaft, metal volute, runner diameter 71cm.

According to China's "Hydraulic Turbine Model Preparation Rules", the model of the hydraulic turbine is composed of three parts, each part is separated by a short horizontal line "-".

The first part is composed of Chinese pinyin letters and Arabic numerals, where the pinyin letters indicate the type of water wheel and the Arabic numerals indicate the model of the runner. The model of the runner that enters the spectrum is the specific speed value, the model of the runner that is not included in the spectrum is the number of each unit, and the old model is the number of the model runner; Reversible turbines are indicated by adding "n" after the turbine type.

The second part consists of two Chinese pinyin letters, which represent the layout of the main shaft of the turbine and the characteristics of the diversion chamber.

The third part is the nominal diameter of the turbine runner and other necessary data.

HL300 - Francis type, 300 should be an experimental model. WJ - horizontal metal structure. The size of the 71 model and the diameter of the lower ring of the runner water inlet.

The model number is given, the diameter of the runner is 71cm, the water head, I don't know what kind of runner you are 300, I calculated the 295 (alias F13, PO820) runner, the efficiency should be 90% under this working condition, then the output of the turbine is 437kw

Runner diameter 71cm, horizontal unit, metal volute, Francis runner.

Hydro turbine HL220-WJ-71 indicates the meaning.

Hello dear! Hydro turbine HL220-WJ-71 means the following meaning: it is a hydro turbine Hydro turbine model HL-240-WJ-71, design head 27m, design flow, generator output power 630KW, rated speed 500R min The function of the hydro turbine governor is to control the opening and titer of the water guide blade (paddle relay) by controlling the operating oil volume of the water guide blade relay (paddle relay), and then control the water flow rate of the water turbine to adjust the speed of the water turbine, that is, to adjust the speed of the water turbine.

Hydraulic turbine governor can be divided into single regulating governor and double regulating governor according to the adjustment object, that is, commonly known as monotonic governor and double regulating governor, and can also be divided into mechanical governor (i.e., ST and T type), electrical governor (DST type and DT sail loss), microcomputer governor (i.e., WST type and WT type), etc., and can also be further subdivided into centrifugal flying pendulum, ring spray, stepper motor, hydraulic valve, direct connection, plate pipeline without open pipe, etc. The working principle of the hydraulic turbine governor is basically to compare the speed signal (unit frequency) with the grid frequency (given frequency), and give the electro-hydraulic converter a signal (command) to operate the relay on or off according to its difference to control the flow of water through the turbine and adjust the speed of the turbine.
