Description
Technical field
The present invention relates to a kind of rotary quantitative fuel feeding or supply the fat device.
Background technique
Existing quantitative mainly adopts electromagnetic valve type and magnetic induction type to combine for two kinds for the fat mode.
For electromagnetic valve type, in the intelligent lubricating product, the actuator of its terminal uses the plunger type bi-bit bi-pass to add that the mode of simple magnetic inductor combination realizes supplying at regular time and quantity fat mostly at present; Be exactly to adopt spherical bi-bit bi-pass to add that the mode of magnetic inductor combination realizes supplying at regular time and quantity fat in addition.No matter adopt which kind of mode to realize for fat, it must by solenoid valve electric and dead electricity realizes.(annotate: when electric electromagnet promote spool and be subjected to displacement, make import and outlet connect, during dead electricity,, piston is replied, import this moment and port closing by the action of reset spring of valve body opposite side.) in its tangible practical work process, the service behaviour of electromagnet is also unreliable, is easy to produce defectives such as misoperation, reason is as follows:
1, is subjected to the influence of grease cleaning degree, makes the spool generation clamping stagnation in the solenoid valve sometimes and can't work;
2, be subjected to the influence of grease viscosity, do not have and to have loaded the load of electromagnet initial force with being full of, thereby the spool that can not promote valve inner causes and can't work;
3, because the plunger type two position two-way valve has flow-off when design, but finally grease can overflow by nature, has influenced working environment;
When if certain lubricating point on 4 system pipelines needs the fat amount big, the electric time that gets that electromagnet is set also increases thereupon, is easy to burn out electromagnet like this and causes and can't work;
Even 5 use spherical two position two-way valve as the terminal control valve, if there is dirt in the grease, cause valve when closing, the conical surface blow-by of valve and make valve be in normal open state, thus influenced whole system operation.If adopt the plunger type two position two-way valve, there is such possibility to occur equally.
Concerning magnetic induction type, its basic principle is exactly that the opening and closing two states of the control valve (electromagnet) of forward end carries out work.When it was opened, grease made inner spool be subjected to displacement by this device, the one, and the inner flow passage hole is connected and fuel-displaced, the 2nd, inductor detects this signal and is delivered on the master control cabinet PLC, thereby reaches the so-called fat that supplies at regular time and quantity.This mode, oil quantity are to realize by the time of setting.Its closed condition, lean on the action of reset spring in the magnetic inductor to make inductive head and inductor throw off, sort signal transmit and by module with feedback information to the master control cabinet, this form that self resets slowly realizes by the gap of spool and valve body, if the master control cabinet will make certain magnetic-inductive device in the system carry out the work that does not stop for several times, the magnetic inductor device can't be realized.
As for oil mass is to realize by the time that the master control cabinet is set, but the definition of the oil pump capacity of above-mentioned form " quantitatively " two words is short of, and also is unscientific, is unpractiaca way.If, system pipeline is 100 meters, oil outlet on the pipeline is 30, each fuel-displaced device carries out work by system master cabinet and PLC program, in case the master control cabinet sends work order, certain point on the system pipeline is started working, and make the electromagnet unlatching cause the magnetic-inductive device effect and externally supply fat, but the oil mass setting value of each point and reality is incorrect for the fat amount.Reason is as follows:
1, be subjected to the influence of system pipeline length, pipeline is long more, and the internal pressure loss is big more, and the oil pump capacity of each oil supplying device does not all wait (influence of the pressure loss) in the same units time so.
2, be subjected to the influence of system's lubricant pump delivery pressure, the oil mass that high each point of pressure was exported in the unit time is big, otherwise be little, and the pressure of pump output in fact be not individual steady state value it have the amplitude of oscillation (pressure surge influence).
3, the accuracy of manufacturing of magnetic-inductive device itself can influence what (size of oil outlet, influences such as the precision of spring) of oil pump capacity equally.
Owing to the influence that is subjected to above-mentioned three kinds of reasons, it is to be difficult to control that the oil mass of each point is set, and is the way of thick frame, and there is the grease wasting phenomena to a certain extent in this, is uneconomic.
