Description
Technical field
The present invention relates to a kind of technical field of wind power generation, and in particular to a kind of bearing of wind power generator automatic lubrication installation
And self-lubricate control method.
Background technique
There are two types of modes for large-scale wind driven generator bearing injection lubricating grease at present: (1) being determined using manual grease gun by manpower
Phase is injected in generator bearing room by oil nozzle, petroleum pipeline, and lubricating grease injection rate and injection length interval are by artificially controlling.Its is excellent
Point is that single greasing amount is big, and waste and old grease discharge is more abundant.The disadvantage is that injection length interval, injection rate are difficult to control, it is easy
Bearing is caused to run under lubricating grease excess or oil starvation state and cause bearing fault；In addition, generator is typically in when oiling
Stationary state causes lubrication uneven.(2) using the automatic lubricant pump of included control panel, when controlling daily oiling by control panel
It carves, each oiling number of counter controls is to control motor front and back bearings lubricating grease injection rate, at regular time and quantity to motor bearings
Interior is automatically injected lubricating grease.The current settable time interval of this automatic lubricant pump was a few houres to tens hours, every time
Greasing amount is seldom.Its advantage is that greasing time interval, injection rate can accurately control.The disadvantage is that greasing amount is few every time, waste and old oil
Rouge is not easy to be discharged, and easily causes waste and old fat saponification and blocks oil circuit；Furthermore, it is possible to also in greasing when generator does not rotate, and
And compressor emergency shutdown do not have a power failure in the case where also can timing, cause the problem of greasing unevenness and greasing amount inaccuracy.
Summary of the invention
In view of this, the problem to be solved in the present invention is to provide a kind of bearing of wind power generator automatic lubrication installation and automatically
Control method is lubricated, and then solves few, the waste and old grease using the existing each greasing amount of greasing device and method and is not easy to be discharged, easily
Cause waste and old fat saponification and block oil circuit, in the case that compressor emergency shutdown does not have a power failure also can timing cause greasing uneven and greasing amount
The problem of inaccuracy.
The present invention solves above-mentioned technical problem by following technological means:
In a first aspect, a kind of bearing of wind power generator automatic lubrication installation provided by the invention, including being mounted on generator
Lubricating pump, lubricating oil pipe, assistant junction box, contactor, controller are provided with power signal line and failure report on the lubricating pump
Alert signal wire, the power signal line and failure alarm signal line are connected electrically on assistant junction box, assistant junction box with contact
Device electrical connection, contactless contactor connector are electrically connected with the controller.
Further, the lubricating pump has the function of to shut down current failure memory and long timing ability, when the long timing is from 0
When timing is to 9999.
Further, the lubricating pump power signal line is also connect with wind generating set main control system.
Further, on the lubricating pump setting there are two oil outlet, two oil outlets respectively with two lubricating oil pipes
Connection, the lubricating oil pipe other end are separately connected AS end bearing and BS end bearing, are additionally provided with temperature close to the pouring orifice position
Sensor, the temperature sensor are electrically connected with the controller.
Second aspect, a kind of control method using the bearing of wind power generator automatic lubrication installation include automatic note
Rouge mode and manual greasing mode, under the automatic greasing mode, controller obtains generator speed, record lubricating pump overturning
Number, record lubricating pump dwell time T, record bearing temperature data, generator speed are divided into three class and are respectively as follows: S1, big
In 400rpm, S2,200 rpm are between 400rpm, S3, less than 200 rpm；The step carried out under each generator speed class
It is rapid as follows:
S1, when generator speed be greater than 400rpm when, if lubricating pump overturning number be less than N, lubricating pump dwell time T be greater than Tn if
Pump startup operation is lubricated, lubricating pump begins turning greasing, while accumulating lubricating pump overturning number, when lubricating pump overturning number reaches
N times, lubricating pump is out of service and makes to overturn number clearing, while adding up the time out of service；
S2, when generator speed is when 200 rpm are between 400rpm, be that revolving speed backhaul is poor, it is poor that lubricating pump is in revolving speed backhaul
When range, lubricating pump is by the instruction before continuously carrying out revolving speed backhaul difference；
S3, when generator speed is less than 200 rpm, lubricating pump stop, pause add up the time out of service, lubricating pump overturning time
Number pause counts and retains current count.
Further, further include fault alarm program, when generator speed be greater than 400rpm, lubricating pump overturning number be less than N,
After lubricating pump dwell time T is greater than Tn lubrication pump startup operation, lubricating pump is not flipped and the time reaches pre-set value, starting
Fault alarm program remotely informs attendant's alarm condition by control system.
Further, the lubricating pump overturns number
Q is greasing amount；I is that lubricating pump overturns primary greasing amount；D is bearing outside diameter；B is bearing width；Y is and lubrication interval
Relevant coefficient；ρ is lubrication lipid density.
It further, further include manual greasing mode, which enables manual greasing mould independently of remaining all control program
All automatic greasing model programs stop when formula, using manually booting lubricating pump, when the manual greasing mode setting has maximum
Between limit, reach maximum time limitation after automatically switch back into automatic greasing mode.
As shown from the above technical solution, compared with the prior art, the present invention has the following advantages: wind-power electricity generation of the invention
When machine bearing automatic lubrication installation remotely can check and monitor lubrication pump startup, halted state information and greasing amount and interval
Between, automatic lubrication installation has memory function lubrication amount accurate under power failure shutdown status；Bearing of wind power generator of the invention is certainly
Dynamic lubrication control method solves at present according to generator speed, bearing temperature automatic adjustment greasing amount and greasing time interval
Automatic lubricating system time interval is short, each lubricating grease injection rate is small be easy to cause grease separation, is saponified and causes lubricant passage way
The problem of blocking or film output amount deficiency.Generator is avoided simultaneously the feelings also not having a power failure in greasing, compressor emergency shutdown when rotating
It also can timing, greasing be uneven and the problem of greasing amount inaccuracy under condition.
