Abstract
The invention belongs to the hydraulic technical field and relates to an installation valve block for a gear case of a wind turbine generator, capable of performing online monitoring. The valve block for the gear case of the wind turbine generator is characterized in that the installation valve block is additionally arranged between the gear case and a filter drum, and oil is led out to an oil sensor by an oil extraction block to be monitored on line. The oil extraction block and the gear case are in threaded connection by a locking part of the installation valve; the oil extraction block and the filter drum are mutually connected in the manner of fastening by a transfer block; two connectors are two bypaths respectively arranged on side faces of the middle part of the oil extraction block; oil before being filtered in the gear case is led out through the oil extraction block and is conveyed to a front-end sensor to be monitored; the oil after being monitored by the front-end sensor flows back to the oil extraction block through the connectors of the oil extraction block; and then, the oil flows into the filter drum to be filtered, and therefore, the online monitoring of the oil in the gear case of the wind turbine generator is realized. Through performing the online monitoring on the oil in the gear case, the early failure of the gear case is identified and the condition-based maintenance is performed; and as posterior maintenance or periodic maintenance is changed into the condition-based maintenance, the overall maintenance efficiency and the operational reliability of the wind turbine generator are promoted.
Description
Technical field
The invention belongs to technical field of hydraulic pressure, relate to a kind of can the installation valve block for gear case of wind turbine of on-line monitoring.
Background technique
Gearbox of wind turbine is the critical piece of wind power generating set, and wherein Oil Quality is the most important factor affecting its working life: wear metal particle is in the degree of wear of meeting accelerating gear; The viscosity of fluid is crossed conference and is caused oil liquid temperature in greasing to raise, and has influence on the lubrication of gear-box; Moisture in Lube Oil & can destroy the oil film that lubricant oil is formed, and accelerates organic acid to corrosion of metal effect.Therefore to the on-line monitoring of wind turbine generator gearbox oil liquid quality, effectively can play forewarning function, and in time change rotten fluid, to improve gear-box working life.
At present, the gearbox of wind turbine 1 used directly is connected with the mode of filter cylinder 6 by screw thread, and the fluid in gear-box 1 flow to filter cylinder 6, after filter cylinder 6 filters, enters cooling unit, is finally circulated again in gear-box 1 and lubricates, as shown in Figure 1.Because gearbox of wind turbine is externally without drawing hydraulic fluid port, in oil liquid detection process, the oil mode adopting off-line, cannot realize the on-line monitoring to fluid more.In testing process, need equipment from gear-box, to extract fluid to detect the change of quality under the situation of shutting down, or when disengage gear case the degree of wear of measuring gear case, the requirement of real-time that industrial field device detects and safeguards can not be met; And on-line monitoring method is getting in liquid process the structure needing to change gear-box, this process increases design cost and the expense of gear-box.
Summary of the invention
In order to overcome the deficiency of existing wind turbine generator gearbox oil liquid offline inspection mode, the present invention proposes a kind of installation valve block for gear case of wind turbine.
Technical solution of the present invention is: the locking member that is linked in sequence between gear-box and filter cylinder, oil out port, oil-feed interface, get oil clot and switching part, wherein oil out port and oil-feed interface are get the bypass outputed oil clot side, the oil outlet got on oil clot communicates with the filter front oil duct on gear-box, and the oil outlet got on oil clot communicates with oil out port; The center of getting oil clot has the center hole communicated with the spill port on gear-box and filter cylinder, the oil-feed interface got on oil clot communicates with the oil inlet hole got on oil clot, oil inlet hole communicates with the spill port on filter cylinder, get oil clot the external diameter of gear-box contact segment is provided with boss and is connected with gear-box with locking member, get oil clot and be threaded with filter cylinder by switching part.
Described locking member is enclosed within to be got line slip of going forward side by side outside oil clot and is connected, and locking member will be got oil clot by the mode of screw thread and dock with gear-box and be connected.
The present invention is installed additional and is installed valve block between gear-box and filter cylinder, and is drawn by fluid by getting oil clot, and the locking member of installation valve block will be got oil clot by the mode of screw thread and be connected with gear-box, and switching part then will be got oil clot and be connected with filter cylinder is fastening; Interface is then the bypass of getting side in the middle part of oil clot and outputing, by getting oil clot, the fluid before filtration in gear-box is drawn and reached front end sensors, the interface of fluid again through getting oil clot after front end sensors monitoring is got back to and is got oil clot, then flow in filter cylinder and carry out filtering and be back in gear-box oil system, reach wind turbine generator gearbox oil liquid on-line monitoring object.
The advantage that the present invention has and beneficial effect:
For existing installation valve block for gear case of wind turbine; the mode of oil liquid monitoring many employings off-line; in testing process, need equipment from gear-box, to extract fluid to detect the change of its quality under the situation of shutting down; or when disengage gear case the degree of wear of measuring gear case, the requirement of real-time that industrial field device detects and safeguards can not be met.The present invention designs gear-box according to the feature of gearbox of wind turbine and installs valve block, and is installed between gear-box and filter cylinder, the fluid in gear-box is led to front end sensors is carried out on-line monitoring by the oil clot of getting installed on valve block.
By the Real-Time Monitoring to gear case of blower fluid data, can to make prediction assessment to the operation conditions of gear-box, change the maintenance based on state into by correction maintenance or periodic maintenance, promote the overall maintenance efficiency of Wind turbines, reduce the reliability of maintenance cost and raising running of wind generating set; The method tests its wear condition without the need to disengage gear case simultaneously, by the online data of front end sensors Real-time Obtaining gear-box fluid, identifies the initial failure of gear-box and carries out condition based maintenance, thus improves the working life of gear-box.
