He is connected in channel 15 with oil liquid, gas slip ring 7, is also equipped with gate valve 8 on other channels 15.Setting for storage tank 13, can
To store the waste oil exhaust gas of required lubricating cooling oil and discharge in storage tank 13, will not pollute.
The information parameter needed can be acquired by signal slip ring 4 inside PLC control system 12 and lubricating oil is calculated with this
Injection rate, the calculation formula set in program are as follows:
Lubricating oil fuel delivery are as follows: Q=0.75hb ν
Wherein h is minimum mucosal thickness needed for bearing, and b is loading ability of bearing sector width, and ν is bearing revolving speed.
ψ is relative gap, and s is bearing minimum clearance, and d is bearing diameter.
For using oil cooled bearing, need to increase oil for amount, groove of the extra oil along bearing shell both sides flows through axis
Hold surface.Take away friction generate heat, cooling oil for amount are as follows:
U is coefficient of friction;F is bearing load.
In formula: θ1For bearing inlet oil temperature, θ2For bearing oil outlet temperature.
Qm=d·R/0.35 QmFor entrance mist of oil amount L/min;R is rotor columns.
It can be seen that Bearing inner lubricating oil injection rate and supplement the period be according to the size of bearing, operating temperature,
Depending on revolving speed and load.It need to guarantee that bearing operating temperatures are maintained at 30 DEG C ~ 61 DEG C and could run well, being more than normal temperature will
Motor bearings is damaged in various degree.It is therefore necessary to the parameter of real time monitoring, these parameters can pass through 4 signal slip rings
It can be timely fed back in PLC control system 12, and can be presented on display module 11, the exhaust gas waste oil of discharge can be from other
Channel 15 is vented back to storage tank 13 under the control of gate valve 8, and one is circulated throughout the rear meeting of PLC control system 12 collecting signal again
Parameter adjusts oil liquid again by flow control valve 9 according to preset formula, the flow of gas forms complete closed loop and adjusts system
System.6 mist of oil flow of inlet channel 5 and feed pathway, pressure can accurately be adjusted by key module 10, pressure, temperature, stream
Amount, revolving speed can acquire signal by signal slip ring 4 and show in display module 11 and adjusted in real time by key module 10, and
Settable warning device.
Compared to other lubrication systems, the oil film that fog lubrication is formed is uniformly and continuous, can each friction part of sufficient lubrication；
Compressed air can also take away heat caused by partial frictional, reduce bearing temperature；It is saved and is lubricated using minimal amount of lubricating oil
Cost.Mechanical lubrication in right amount, should be applicable in, a small amount of and high-frequency feed lubrication can reduce oil loss, completely in due course
Lubrication can extend the service life of machine part, this structure can supply correct oil mass in the correct time, automatic and repeat
Lubricate bearing and slide-bar.
