Description
Technical field
The utility model relates to a kind of grease distributor, especially relates to a kind of multiple exit positive displacement grease distributor.
Background technique
At present, in the industries such as metallurgy, mine, building materials, generating and large-scale engineering machinery, original oil box oil supply mode is eliminated gradually in these applications, and applies more lubricant oil, the dispensing device of lubricating grease and system and mainly contain following two kinds: 1, single-line type divides oil system and single-line type separating valve; 2, two-wire system divides oil system and two-wire system separating valve.
Single-line type divides the shortcoming of oil system and single line separating valve comparatively obvious, as long as be exactly certain lubricating point blocking of certain distributor, the institute of this distributor a little all quits work.Comparatively complicated in system, when lubricating point is more, single-line type divides oil system and single-line type separating valve to be easy to the situation occurring because of the blocking of indivedual lubricating point working.Meanwhile, the volume read-out of same distributor can only be identical, can not regulate arbitrarily, and be easy to blocking.
Two-wire system divides oil system and two-wire system separating valve to have following advantage: the function that 1, can realize quantitative fuel feeding.2, have two oil supply loops in system, compared with dividing oil system and point oily device with single-line type, system is not easily collapsed, but the separating valve in this system easily causes oil pump separating valve nearby to bear high pressure and the separating valve underpressure far away apart from oil pump.This system dynamic sealing point is more in addition, and system easily occurs oil leakage phenomenon.
The use solenoid valve occurred in recent years is as the lubrication system of oil supply device, and its principle is connected to solenoid valve between fuel supply line and lubricating point, uses PLC to carry out the switch of Controlling solenoid valve.Also oiling (fat) amount that just have adjusted lubricating point on time of adjustment solenoid valve.The lubrication system of solenoid valve is used to have following shortcoming: 1. normal open fault easily occurs solenoid valve, particularly more at lubricating point, in the lubrication system using solenoid valve also more, as long as there is a solenoid valve generation normal open fault, the waste of lubricant oil and the reduction of system oil pressure will be caused, the grease out of multithread simultaneously will leak out, and pollute working environment.2. solenoid valve commutation thrust is less, because dry oil viscosity is comparatively large, has delayed the turn around time of solenoid valve, has caused measuring error.When ambient temperature is higher, electromagnetic push obviously declines simultaneously.
Chinese patent 200420029881.1 discloses a kind of multi-point self-lubricator, comprising a kind of rotating circulating distributing valve distributed for lubricating grease, this valve is by the valve body fixed and be in transmission connection in drive motor by driving component and the rotatable spool being packaged in valve body by end cap is formed, and spool is provided with cavity.The advantage of this valve is that oil circuit is without undue narrow, to the impurity strong adaptability be mixed in lubricating grease, long service life, not easily blocking, but simultaneously this valve also has its shortcoming: this valve itself can not control lubricant oil to oil mass, each lubricating point be identical to oil mass.There is no the advantage such as existing above-mentioned impurity strong adaptability, long service life, not easily blocking in the market, accurately can control again point oily device of arbitrfary point any lubricant oil oil mass.
Model utility content
Technical problem to be solved in the utility model is to provide the impact that a kind of applicability on oil product is strong, measuring accuracy is not subject to the change of ambient temperature and system pressure, and the multiple exit positive displacement grease distributor that the pressure loss is little.
In order to solve the problems of the technologies described above, the multiple exit positive displacement grease distributor that the utility model provides, comprise a distributor, described distributor comprises a distributor body and distributor mandrel, the drive unit be in transmission connection with described distributor mandrel, be located at multiple valve body oil outlets of different stable state position on described distributor body, described distributor mandrel be provided with mesopore and multiple in different stable state position respectively with multiple described valve body oil outlet spool oil outlet passage of being communicated with corresponding to described mesopore, piston is provided with in oil cylinder, described oil cylinder is divided into two oil pockets by described piston, two hydraulic fluid ports of two position and four-way reversing valves are connected with two oil pockets of described oil cylinder respectively, enter oil pipe to be connected with a hydraulic fluid port of two described position and four-way reversing valves, a hydraulic fluid port of two described position and four-way reversing valves is connected with the described mesopore of described distributor mandrel.
The two ends of described oil cylinder are equipped with the adjusting nut acting on described piston.
Described drive unit is stepper motor.
The square shaft of described stepper motor is connected with the square opening Direct driver of described distributor mandrel.
Adopt the multiple exit positive displacement grease distributor of technique scheme, the stroke of the adjusting nut adjusting piston at oil cylinder two ends, can realize any lubricating point volume read-out it's too late regulating.Volumetric metering, makes measuring accuracy not be subject to the impact of the change of ambient temperature and system pressure.Structure is simple, strong to the applicability of oil product, there will not be shutoff phenomenon.Cost is low, and a set of mechanism can realize the oiling of multiple lubricating point.When the piston in oil cylinder embeds magnet steel, load onto proximity switch at the two ends of oil cylinder simultaneously, self energy lubrication system can be upgraded on the basis of automatic lubricating system.When fueling signal collects master control system, during by PLC feedback signal, then increase video monitoring system, the intelligent menagement of lubrication system can be realized.As: volume read-out controls arbitrarily, and leak stopping is reported to the police, and volume read-out is added up.Arbitrary lubricating point breaks down, and other can work as usual.The square opening (principle with reference to gear coupling) of the square shaft Direct driver spool of stepper motor, simplifies driving mechanism.Owing to adopting the distributor mandrel rotated, have impurity strong adaptability, long service life, not easily blocking, pressure loss in piping is little.Adopt two oil pockets and piston thereof, can accurately control lubricant oil oil mass, the distributor mandrel that the utility model has, different valve body oil outlets can be connected in different stable state positions; , quantitative lubricant oil is discharged.
In sum, the utility model is the multiple exit positive displacement grease distributor that a kind of applicability on oil product is strong, measuring accuracy is not subject to the impact of the change of ambient temperature and system pressure.
