Description of drawings
Fig. 1 is the structural representation of embodiments of the invention one;
Fig. 2 is the structural representation of embodiments of the invention two.
Embodiment
As depicted in figs. 1 and 2, water turbine of the present invention mainly comprises spiral case 1, is arranged on main shaft 2, bearing, bearing chamber and blade (not shown) in the spiral case, the end cap 3 that is arranged on the main shaft two ends and fixedlys connected with spiral case.Spiral case 1 is provided with intake pipe 11, and 11 places arrange turbo charging installation at intake pipe.
In the embodiment shown in fig. 1, intake pipe 11 is provided with a holding part 12, and this holding part hollow is also outwards outstanding.Holding part 12 is communicated with intake pipe, and the holding part installed inside has turbine 4, and the outside is provided with motor cabinet 5, and turbosupercharging motor 6 is fixed on the described motor cabinet and with worm gear drive and is connected.
In the embodiment shown in Figure 2, intake pipe 11 is provided with supercharging passage 13, and the two ends of supercharging passage are communicated with intake pipe, and establishing side in it has turbine 4, and the outside is provided with motor cabinet 5, and turbosupercharging motor 6 is fixed on the described motor cabinet and with worm gear drive and is connected.The angle of the waterexit end of supercharging passage 13 and 11 one-tenth 35 °～45 ° of intake pipes makes the angle of the fluid flow direction in fluid flow direction and the intake pipe in the pressure pipeline between 35 °～45 °, loses with the dynamic pressure that reduces by two fluid streams as far as possible.The fluid resistance of the involutory stream of pipeline butt joint angle has certain influence, the more big flow resistance of butt joint angle is just more big, so control pipeline butt joint corner degree in minimum as far as possible, certainly because problems such as pipe diameter and butt joint place size can not be infinitely small, through repeatedly experiment, comprehensive considering various effects is controlled during the pipeline butt joint at 35 degree to the needs that can satisfy between 45 degree on the engineering as far as possible.The technician can arrange or measure this angle in several ways, for example controls the angle of supercharging passage and intake pipe axis.
In a further embodiment, above-mentioned water turbine also comprises the fan speed monitoring device, the circulating water temperature monitoring device, and be connected with the circulating water temperature monitoring device with the fan speed monitoring device and according to the compensate control apparatus of its parameter adjustment turbosupercharging motor speed.
Working principle of the present invention following (according to the energy compensating policy setting that consumes the minimum energy or calculating relevant parameter):
A. the compensation device power of motor is set: establishing fan shaft power is W
1, compensation device motor operate power is W
2, flow is Q, and system's pressure more than needed is H, and turbine efficiency is η
1, the compensation device transmission efficiency is η
2, then the motor output power is selected as follows: W
2=(W
1/ η
1-9.81 * Q * H)/η
2, in the formula: power W unit is kW, flow Q unit is m
3/ s, pressure H are m.
B. flow velocity is selected: according to the required compensation energy of system, select flow velocity and the former pipe flow speed of compensation device to be complementary,
Flow velocity is preferably controlled between 1.8m/s～2m/s, and then the compensation device caliber is selected as follows: D=2 * (Q/3.14V)
1/2/ 1000
In the formula: caliber D unit is mm, and flow velocity V unit is m/s, and flow Q unit is m
3/ s.
C. the automatic control of compensation device: in a further embodiment, two supervisory devices of the present invention: rotation speed of fan and circulating water temperature monitoring device, these two devices and compensation device electric control valve and motor control assembly interlocking, when season, ambient temperature or production heat load were low, adjust valve opening and the rotation speed of fan of compensation device by the temperature dividing value of limiting, stop transport until motor, otherwise when circulating water temperature raises gradually, open motor and corresponding adjustment valve opening and rotation speed of fan.Adjustment valve opening and rotation speed of fan are that the flow of reduction compensation device also is to reduce energy consumption of electrical machinery, and this technology is limited utilization compensation energy, makes the compensation energy drop to minimum.
With a 4000m
3/ m cooling system is that example illustrates energy-saving effect of the present invention, establishes fan motor operate power 175
KW, fan shaft power 145kW, system's pressure more than needed calculates by design or the 5m that generally investigates lower limit, and then the compensation device operate power is W
2=(W
1/ η
1-9.81 * Q * H)/η
2
=(145/0.92-9.81×(4000/3600)×5)÷0.9
=(157.6-54.5)÷0.9
=114.5(kW) then the compensation device motor power consumption is saved 175-114.5=60.5(kW than former fan motor power consumption).
This shows that when the present invention compensated hydraulic turbine operation in summer, the operation power consumption was compared by the minimum saving of last example 60.5kW with motor tower motor power consumption.And in other seasons, can stop supercharging device, and need not energy consumption, therefore overall energy-conservation is tangible.The present invention is applicable to the circulation cooling system of any operating mode.
In a word, except above-mentioned advantage, the present invention utilizes pressure more than needed to do work to drive blower fan of cooling tower, has removed former cooling system motor, speed reducer, transmission shaft, has the saving energy, reduces the advantage of noise; And need not electric controller, cable and speed reducer, further can reduce and safeguard intensity and cost, and solve summer and winter environment in spring and autumn different and energy loss and the water loss that wafts that institute's required airflow different band is come.
