Abstract
The utility model relates to a periodic pulse type oil mist alternating injection lubrication system which belongs to an oil mist lubrication system pf pump group of oil and chemical equipment. The oil mist alternating injection lubrication system is composed of a touch screen, an electromagnetic valve, an oil mist generator, a flameproof circuit breaker, etc., and is characterized in that a PLC is adopted to be a program controller for injection time, period, pulse and the injection of lubricating oil on a bearing surface. The electromagnetic valve is adopted, a power cord of the electromagnetic valve is connected with an intermediate relay, and a contact coil of the intermediate relay is connected with the PLC. The lubrication system overcomes the aerosome generated when a bearing is rotated, so as to cause the lubricating oil mist to be fully contacted with rotary equipment, thereby enhancing the utilization rate of the lubricating oil mist, and ensuring that timely lubrication is carried out on the rotary equipment. At the same time, because the oil mist utilization rate is enhanced, no residual mist is escaped, the pollution on the environment is avoided.
Description
Affiliated technical field
The novel oil mist lubrication that relates to oil, chemical industry equipment group of pump of this use, especially a kind of lubrication system of group of pump being carried out periodicity, the oil mist lubrication of pulse alternating spray.
Background technique
At present, domestic oil mist system, the general diffuse type lubricating system that adopts, it is mist of oil about 1 micron that its lubricant oil becomes particle diameter after by oil fog generator, be called the drier oil mist, the drier oil mist by the mist of oil line transportation to bearing bore, before contact lubricated point condensing for particle diameter be that wet oil mist about 20 microns is lubricated.Because the very low 0.2MPa that is roughly of mist of oil pressure of this moment, formed wet oil mist mainly contacts the bearing of high speed rotating by the form of disperse, bearing can form airbond on the surface in its rotation, make mist of oil can not well arrive bearing surface, so the lubricating system of diffuse type can not solve lubricating efficiency well, simultaneously, the lubricating oil oil film that forms in lubricated is very thin, can not satisfy lubricated requirement.In addition, because the problem of the airbond of the bearing surface of rotation, a large amount of mist of oils are not utilized fully, and a part escapes into the pollution that causes environment in the air by the place, slit of bearing housing.
Summary of the invention
The purpose of this utility model is to produce airbond when rotated for overcoming bearing, make the lubricant oil mist of oil contact rotating equipment fully, improve the utilization ratio of lubricant oil mist of oil, guarantee rotating equipment is carried out lubricating timely, and proposed a kind of periodicity, pulsed alternating spray oil mist system.
The purpose of this utility model is achieved in that periodically, pulsed alternating spray oil mist system, comprise compositions such as touch screen, solenoid valve, oil fog generator, flameproof circuit breaker, it is characterized in that: employing PLC does discharge time, cycle, pulse and lubricant oil is ejected into the programming controller of bearing surface; Adopt solenoid valve 15, power of electromagnetic valve line 13 connects auxiliary reclays 14, and the contact coil by auxiliary reclay is connected with PLC; Oil fog generator 7 is installed on the lubricant oil fuel tank 5, oil fog generator level meter 4 is installed on oil fog generator, flameproof circuit breaker 6 and pressure regulator valve 2 are installed on the panel of control cabinet 3, touch screen 1 is connected with PLC with pneumatic motor 8, at the outside of control cabinet 3 returning apparatus the fuel tank of cleaning blind flange 16 is arranged.
Periodically, the working principle of pulsed alternating spray oil mist system is: lubricant oil forms Venturi effect through oil fog generator in its throat, the generation particle diameter is 1 micron a mist of oil, mist of oil is extremely needing on the lubricated equipment by the mist of oil line transportation, every certain interval of time, just periodically introduce high-pressure air, mist of oil is ejected into bearing surface, forms oil film, equipment is lubricated.On the fog pipeline of a whole set of oil mist system and mist of oil transfer line, increase solenoid valve, adopt the power of electromagnetic valve line of 24V (DC) to receive on the auxiliary reclay, the contact is connected on the PLC in the control cabinet according to the contact coil of auxiliary reclay.The program that PLC (programming controller) inside downloads according to the programmer according to the scene parameter of bearing rotation in fact, is set discharge time.
The utility model has overcome bearing and has produced airbond when rotated, makes the lubricant oil mist of oil contact rotating equipment fully, will improve the utilization ratio of lubricant oil mist of oil like this, guarantees rotating equipment is carried out lubricated timely.Simultaneously, because the rising of mist of oil utilization ratio had not both had residual mist to overflow,, also just avoided environment is polluted owing to there is not residual mist in bearing bore, to overflow.
Description of drawings
Be described further below in conjunction with drawings and Examples.
Fig. 1 is this use new embodiment mist of oil generation cabinet front plate schematic representation;
Fig. 2 is the utility model embodiment's a mist of oil generation cabinet cut-away view.
