Description
Technical field
The present invention relates to thin oil lubricating equipment technical field, refer more particularly to a kind of Special absorption-assisting device for thin-oil lubricating equipment.
Background technique
Thin oil lubricating equipment is mainly conveyed into lubricating oil by defeated oil transfer pump the friction position of machinery equipment, between the machine parts of relative motion, form oil film, thereby reduce the friction and wear of part, friction position is rinsed simultaneously, and take away heat, guarantee equipment runs well for a long time, extends the working life of machinery equipment.
Ensure that basic requirement is: defeated oil transfer pump must be provided with oil transfer pump for subsequent use, in the outlet of two pumps, one-way valve is set simultaneously to the long-term continuous continual fuel feeding of machinery equipment, i.e. a job, one is for subsequent use.For high low pressure thin oil lubricating equipment, high and low pressure system averages does not arrange oil transfer pump for subsequent use, when preventing that work oil transfer pump from breaking down, and oil transfer pump work for subsequent use.But the key of problem is also: the oil that must leave enough spaces and hold lubricated system-down due to thin oil lubricating equipment fuel tank time, system oil return or top petrol tank get off; therefore; the operating fluid level of fuel tank; be generally 1/3 left and right of fuel tank effective height; also has certain elevation from the defeated oil transfer pump entrance that is installed on top of oil-tank; defeated oil transfer pump just must ensure to have enough suction capacities in the time starting each time, just can make the normal oil suction work of defeated oil transfer pump.When defeated oil transfer pump work, mainly lean on gear (gear pump) or blade (vane pump) or screw rod (screw pump) to rotate to form certain negative pressure and oil suction, after pump works long hours, its sealing surface all can be subject to wearing and tearing to a certain extent, after sealing surface wear, sealing surface gap increases, its suction capacity will decline, so that can not oil suction aggravate the wearing and tearing of sealing surface while causing start next time because of long-time idle running, defeated oil transfer pump is damaged.Particularly adopt the occasion of top petrol tank fuel feeding, when oil transfer pump again starts after stand-by state a period of time, to there will be following problems: in pump chamber, noresidue fluid forms and produces the oil film that enough sucks vacuum, and the fluid that comes from top petrol tank oil level elevation produces static pressure head to pump discharge one-way valve, the gas that pump rotates emptying discharge accelerates internal leakage because pushing one-way valve open, therefore, even if pump seal face did not did not also wear and tear, also can cause the normally oil suction work of defeated oil transfer pump because of the fit up gap problem of pump in manufacture process.This problem is also a difficult problem that troubles for a long time and make manufacturing firm and applying unit headache.
First traditional solution is in type selecting, by adopting suction capacity good, move the slightly smaller defeated oil transfer pump of screw type of more steady and frayed impact etc., next is exactly to reduce defeated oil transfer pump to inhale journey as far as possible, emptying time while shortening defeated oil transfer pump startup, besides defeated oil transfer pump and fuel tank are separated separately and arrange, make fuel tank liquid level certainly flow into defeated oil transfer pump higher than pump intake, aforementioned two kinds of methods are to increasing the working life of pump, normally use but can not meet the long-term of defeated oil transfer pump, and the third processing method can not meet most working condition requirement.
Summary of the invention
The object of the present invention is to provide one to utilize internal negative pressure to suck lubricant oil from low level fuel tank, and by progressively emptying inner air of oil transfer pump suction, and keep the highest liquid level of lubricant oil to be positioned at all the time the Special absorption-assisting device for thin-oil lubricating equipment on oil delivery pump body entrance.
In order to achieve the above object, the present invention is achieved through the following technical solutions: a kind of Special absorption-assisting device for thin-oil lubricating equipment comprises oil storage tank 1, fuel sucking pipe 2, oil outlet tube 3 and emptier 4, wherein oil storage tank 1 top is provided with oiling cap 5, side is provided with oily vernier form 6, described fuel sucking pipe 2 is connected with oil storage tank 1 flange in the bottom, its one end is placed in oil storage tank 1, port is upward and higher than graduation line shown in vernier form 6, the other end is placed in the lubricating oil that fuel tank deposits, described oil outlet tube 3 one end are placed in oil storage tank 1, port down and be positioned at oil storage tank 1 low level, the other end is positioned at outside oil storage tank 1, and be connected with the in-line 7 of thin oil lubricant oil transfer pump, described emptier 4 is connected with in-line 7 bodys with the top of oil storage tank 1 respectively, this device reaches oil ga(u)ge graduation line when above at the interior injection lubricant oil of oil storage tank 1 in advance, tighten oiling cap sealing, oil transfer pump starts running, under the effect of suction, lubricant oil is from flowing to oil transfer pump, make the certain negative pressure of formation in oil storage tank 1 and fuel sucking pipe 2 mouths of pipe, lubricant oil in atmospheric effect lower fuel tank is sucked in oil storage tank 1 by fuel sucking pipe 2, fuel sucking pipe oil outlet end is higher than vernier form graduation line, and oil outlet tube filler opening is positioned at oil storage tank low level, thereby ensure the fuel feeding to oil transfer pump, the air entering in tank with lubricant oil enters in-line 7 by emptier 4, suck and take away gradually by oil transfer pump, thereby keep the interior pressure-reduction level of oil storage tank 1, make the lubricating oil level sucking on oil ga(u)ge graduation line, the long-term normal operation needs of thin oil lubricating equipment are met.
As preferably, described emptier 4 is made up of emptying pipe 8 and the joint 9 of Ф 6, and joint 9 is connected to emptying pipe 8 two ends, and is connected with the body of in-line 7 with oil storage tank 1 top respectively.
As optimization, described fuel sucking pipe 2 is straight-through tube, is connected with oil storage tank 1 flange in the bottom along oil storage tank 1 centerline direction, improves the suction efficiency of negative pressure suction lubricant oil.
Described liquid container 1 actual volume is not less than 2 times of fuel sucking pipe 2 cavity volume, to ensure, after lubricant oil input oil pump, forming enough negative pressure in tank body, keeps fuel sucking pipe to stablize lubricant oil intake.
Compared with prior art, the invention has the beneficial effects as follows: this apparatus structure is simply compact, utilize lubricant oil in tight storage tank to be formed negative pressure by oil transfer pump sucking-off, lubricant oil in fuel tank is sucked to oil storage tank from fuel sucking pipe, be positioned at fuel sucking pipe and the design of oil outlet tube hydraulic fluid port high-low-position of oil storage tank, ensure the fuel feeding to oil transfer pump, in addition pass through emptier, in tank, gas is progressively siphoned away under the effect of pump pressure, thereby oil suction vacuum degree in maintenance oil storage tank, when oil transfer pump starts after shutting down again, as long as the flow of oil transfer pump can meet system fuel feeding and require, thereby fundamentally meet the long-term normal operation of thin oil lubricating equipment, the working life of also greatly having improved thin oil lubricating equipment oil transfer pump simultaneously.
