Embodiment
embodiment 1
Shown in Fig. 1 and Fig. 2, the utility model is lubricant grease pumping system, and it comprises the pump housing 1, grease source, proportional electromagnetic valve 9 and source of the gas, and (grease source is often referred to lubricating oil tank, and source of the gas is often referred to air bells compressor-air pump; Grease source and source of the gas are prior art, thus not shown, also do not repeat at this).
The pump housing 1 forms primarily of body portion and end cap 8.
Wherein, body portion is made up of the larger large footpath section of diameter and the less path section of diameter, is conducive to the compact structure making the pump housing 1 like this.In the path section of the pump housing 1, offer a piston cavity 2, concrete, this piston cavity 2 drives into (diameter specifically offered and the degree of depth should be determined depending on the lubricant grease supply flow of use equipment) from the path section end face indent of the pump housing 1; In addition, the end face of path section also offers two air flues, namely the inner of the first air flue 10 and the second air flue 11, first air flue 10 passes to the bottom place of piston cavity 2, and the inner of the second air flue 11 passes to the outside place of piston cavity 2.
End cap 8 is fixed on the path section end face of the pump housing 1 by Sealings such as fastening piece and seal ring such as fastening screw trip bolts.With this, jointly form complete piston cavity 2 by the body portion of end cap 8 and the pump housing 1.
Piston 7 and Returnning spring 17 is provided with in piston cavity 2.The T-shaped shape of external frame of piston 7, the diameter of piston cap coupling piston cavity 2, the Pressure channel 16 of the corresponding grease channel of piston rod also stretches into, and this side surface connecting piston rod is provided with cushion, avoids piston 7 in to-and-fro motion, block the first air flue 10 by cushion at piston cap.Thus, guiding is formed to the to-and-fro motion of piston 7 in piston cavity 2.Certainly, the annulus access that coordinating between piston rod with Pressure channel 16 fully should reserve grease and pass through.Returnning spring 17 one end abuts the piston cap of piston 7, and the other end abuts end cap 8, and Returnning spring 17 had both facilitated piston 7 and resetted in piston cavity 2, also serves cushion effect simultaneously, avoids piston 7 in to-and-fro motion, block the second air flue 11.
End cap 8 also offers air flue, namely air flue correspondingly with the first air flue 10 on the pump housing 1 body portion to communicate (being referred to as first air flue 10 on end cap 8 and the pump housing 1 body portion), and another is corresponding with the second air flue 11 on the pump housing 1 body portion communicates (being referred to as the second air flue 11 on end cap 8 and the pump housing 1 body portion).The first air flue 10 on end cap 8 and the exposed surface at end cap 8 of end of the second air flue 11, based on offering processing reason, the outer wall of end cap 8 circumference is provided with the screw plug 15 of sealing first air flue 10.
The grease channel in threeway shape is offered in the large footpath section of the pump housing 1 body portion, concrete, grease channel forms threeway shape structure primarily of the suction passage 3 of radial direction and the Pressure channel 16 of oil drain passage 5 and axis, and the inner of suction passage 3, oil drain passage 5 and Pressure channel 16 pools together.The outer end of suction passage 3 is exposed at the wall of the pump housing 1 body portion large footpath section, the outer end of this suction passage 3 is sealed by pipe joint 14 and is connected fuel sucking pipe 12, namely suction passage 3 connects fuel sucking pipe 12 by pipe joint 14, is provided with intake side one-way valve 4 in suction passage 3; This intake side one-way valve 4 forms with the spring of corresponding conical surface seal primarily of the conical surface section in suction passage 3, the blocking steel ball being assemblied in conical surface section place, abutting steel ball, and in contrast, the position of steel ball is near the outer end of suction passage 3.The outer end of oil drain passage 5 is exposed at the wall of the pump housing 1 body portion large footpath section, the outer end of this oil drain passage 5 is sealed by pipe joint 14 and is connected oil exit pipe 13, namely oil drain passage 5 connects oil exit pipe 13 by pipe joint 14, is provided with oil extraction side one-way valve 6 in oil drain passage 5; This oil extraction side one-way valve 6 forms with the spring of corresponding conical surface seal primarily of the conical surface section on oil drain passage 5, the blocking steel ball being assemblied in conical surface section place, abutting steel ball, and in contrast, the position of spring is near the outer end of oil drain passage 5.Pressure channel 16 axially extends until exposed in the bottom surface of piston cavity 2, and namely the outer end of Pressure channel 16 communicates with piston cavity 2.Aforementioned suction passage 3, oil drain passage 5 and Pressure channel 16 specifically offer diameter, should determine depending on the lubricant grease supply flow of use equipment.The effect of aforementioned intake side one-way valve 4 prevents the lubricant grease adverse current sucked from entering fuel sucking pipe 12, and the effect of oil extraction side one-way valve 6 prevents the lubricant grease adverse current of discharging from entering piston cavity 2.
The other end of above-mentioned fuel sucking pipe 12 extends to grease source place, and namely the other end of fuel sucking pipe 12 and grease source place connect.The other end of above-mentioned oil exit pipe 13 extends to oil separator (the multiple lubricating component places in machinery), the corresponding each lubricating component place in machinery of oil separator (or, when the lubricating component place in machinery only has one, directly oil exit pipe 13 is extended to the lubricating component place of machinery, do not need oil separator).
Aforementioned proportion solenoid valve 9(concrete structure is existing routine techniques) be fixed on the end cap 8 of the pump housing 1, this proportional electromagnetic valve 9 is arranged on the gas pipeline of source of the gas.Two ports of proportional electromagnetic valve 9 seal with the first air flue 10 on end cap 8 and the second air flue 11 respectively and are connected.
Source of the gas of the present utility model, proportional electromagnetic valve 9, first air flue 10 and the second air flue 11 constitute pneumatic link, promote the reciprocating of piston 7 correspondence in piston cavity 2 with this.The to-and-fro motion of piston 7 makes the volume of piston cavity 2 repeatedly change, so the suction of correspondence, removal of lubricant fat.Under the specific prerequisite of physical dimension of grease channel and piston cavity 2, the suction of lubricant grease, the flow of discharge carry out regulable control by proportional electromagnetic valve 9.
embodiment 2
Other structure of the present embodiment is identical with embodiment 1, difference is: the first air flue and the second air flue are offered mode with radial direction respectively and outputed in the path section of pump housing body portion, then be connected tracheae with the outer end of the second air flue respectively by pipe joint at the first air flue, the tracheae of two air flues is connected on proportional electromagnetic valve.So will reduce shaping difficulty of the present utility model, but structural compactness can be affected to a certain extent.
The various embodiments described above only in order to the utility model to be described, are not intended to limit.Although be described in detail the utility model with reference to above-mentioned concrete technological scheme, those of ordinary skill in the art has been to be understood that: it still can be modified to above-mentioned concrete technological scheme, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of technical solutions of the utility model.
