Abstract
The utility model relates to a monitoring device for oil and water in a turbine runner body, in particular to a monitoring device for detecting leakage of the oil and water in the turbine runner body. The utility model mainly aims at solving the defects that the oil and water leakage in the turbine runner body in the prior art is difficult to find timely, and provides a monitoring device which has a extremely simple structure and can timely reflecting the leakage situations of oil and water in the turbine runner body. The specific technical scheme is as follows: the monitoring device for oil and water in the turbine runner body is positioned on a spindle inside the runner body and is characterized in that oil leakage holes are arranged outwards from the inner center to a bearing bush at the outer layer of the spindle.
Description
Technical field
The utility model relates to water turbine interior oil water monitoring device, especially a kind of monitoring device that detects profit leakage in the Hydraulic Turbine Rotor.
Background technique
In the water wheels unit operation, the body fault, the security incident that cause because of the leakage of oil seepage problem are inevitable.On the one hand, need on producing, technology study improvement; On the other hand, reliable monitoring system can not be ignored the protective action of water wheels body.For example detect the device of leakage of oil seepage problem in the Hydraulic Turbine Rotor, except to installing the requirement accident of this province monitoring sensitivity, the installation of device proper can not hinder the normal operation of water wheels body.Therefore, for the monitoring system of water wheels unit, technology focuses on improving sensitivity, simplifies the structure of detection device simultaneously.。
Summary of the invention
The utility model is primarily aimed in the prior art for Hydraulic Turbine Rotor inside profit leakage problem and is difficult to the shortcoming in time found, designed a kind of structure very simple, in time react the monitoring device of the inner profit leakage situation of rotary wheel of water turbine.
Above-mentioned technical problem of the present utility model is implemented by the following technical programs: profit monitoring device in a kind of Hydraulic Turbine Rotor, be positioned on the main shaft of web inside, and described main shaft inside therefrom is provided with oil leaking hole until outer field bearing shell outside the mind-set.This oil leaking hole is the key of monitoring device, and the profit of seepage could be sensed by the induction installation of web outside after flowing into oil leaking hole.
As preferably, described bearing shell periphery is provided with rotary arm bearing, connects pivoted arm on the rotary arm bearing, and the pivoted arm upper end connects blade; This rotary arm bearing is arranged on the outer bearing shell of main shaft with the form of piecemeal pad bearing; Blade pass is crossed pivoted arm, rotary arm bearing links to each other with main shaft, and when water turbine ran well, rotating blades formed the passage of water inlet and water outlet.
As preferably, the top of the end face that described blade links to each other with web is provided with seal ring, is provided with between end face bottom and the web to float watt.All there is less clearance in surface of contact between blade and the web, in order to make that break-in is good between surface of contact, needs extending oil to prevent wearing and tearing and stuck, and the purpose that seal ring is set is to control leakage of oil, prevents that leakage of oil is too much.
As preferably, there is the cavity of shape distortion described web inside, fills the butter body in the cavity.Because moisture and butter are immiscible, the moisture of seepage flows along the butter body in cavity, flows into the interior moisture of oil leaking hole flows to the alignment of shafts along the duct axial clearance.
As preferably, described oil leaking hole is positioned at the neutral position of the main shaft portion that stretches into web, and this oil through is by the axial clearance 9 and web external communications of the alignment of shafts.This oil through is by axial gap and the runner external communications of the alignment of shafts, after moisture flows out from oil leaking hole, flows to the induction installation of runner outside along the axial clearance of the alignment of shafts, makes the cue that leakage of oil is seeped water by induction installation.
In sum, the utility model is compared with prior art and is had following advantage.
The utility model adopts simple structure, principle, and the situation of profit seepage is detected, and makes reaction timely, and favourable making timely with operator handled, and avoids water turbine is caused badly damaged even causes a serious accident.
Monitoring device described in the utility model is only offered through hole at the main spindle's of web inside, and the cavity in the web is made improvements slightly, not at the unnecessary parts of the inner increase of web, cause obstruction can not for the normal operation of runner unit.
Description of drawings
Fig. 1 is the figure that partly cuts open of the present utility model.
Among the figure: 1, web, 2, main shaft, 3, bearing shell, 4, oil leaking hole, 5, pivoted arm, 6, rotary arm bearing, 7, blade, 8, cavity, 9, axial clearance, 10, seal ring, 11, float watt.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, the profit monitoring device is positioned on the main shaft 2 that stretches into web 1 inside in the Hydraulic Turbine Rotor, and main shaft inside therefrom is provided with a through hole until outer field bearing shell 3 outside the mind-set, is oil leaking hole 4; Oil leaking hole 4 is positioned at the neutral position of main shaft 2 parts that stretch into web, and this oil leaking hole 4 is by the axial clearance 9 and web 1 external communications at main shaft 2 centers.
Described bearing shell 3 peripheries are provided with rotary arm bearing 6 with the form of piecemeal pad bearing, connect pivoted arm 5 on the rotary arm bearing 6, pivoted arm 5 upper ends connect blade 7, and the top of the end face that blade 7 links to each other with web 1 is provided with seal ring 10, are provided with unsteady watt 11 between end face bottom and the web.
There is the cavity 8 of shape distortion described web inside, fills the butter body in the cavity.
When the leakage of oil infiltration occurring, moisture in the infiltration web 1 flows to cavity 8 from the joint gap of each parts, in cavity 8, flow with the immiscible butter body of moisture, after flowing out cavity 8, moisture flows to the oil leaking hole 4 on the bearing shell 3, then gap 9 flow to web 1 outside vertically, and this moment, the induction installation of web 1 outside operated, and provided the cue of leakage of oil infiltration.Operator make counter-measure then according to signal.
In time finding leakage of oil infiltration phenomenon, and make fast and handling, to reduce the suffered infringement of water wheels body as far as possible, also is a kind of important way of protecting water turbine and avoiding accident to take place.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
