Fig. 1 also is shown specifically the structure of greasing tube 11 in this greasing external member.Greasing tube 11 1 ends are communicated with high pressure ram's horns 191 by high pressure hose 118, and high pressure hose 118 is provided with needle valve 119 with high pressure ram's horns 191 junction; Greasing tube 11 the other ends inject seal gease to the greasing service equipment such as wellhead flange, production valve etc. by greasing high pressure hose 117 and grease gun head.In the embodiment shown in fig. 1, high pressure ram's horns 191 also is being communicated with other two greasing tubes, these two greasing tubes are identical with greasing tube 11 with the Placement of high pressure ram's horns 191, and the junction at two high pressure hoses that are communicated with these two greasing tubes and high pressure ram's horns 191 and high pressure ram's horns 191 is provided with needle valve 129 and 139 respectively.Oil hydraulic pump 18 1 ends are communicated with high pressure ram's horns 191 by high pressure hose 192, and the other end is communicated with hydraulic oil container 1 by low pressure oil inlet pipe 101.Certainly, be example just here with corresponding three the greasing tubes of an oil hydraulic pump, the utility model can also have the situation of corresponding other quantity greasing tubes of an oil hydraulic pump.
Piston 111 is divided into charge of oil chamber and dress fat chamber with the inner space of greasing tube 11, and the charge of oil chamber is by greasing tube left end cap 112, sidewall and piston 111 sealings, and dress fat chamber is by greasing tube right end cap 114, sidewall and piston 111 sealings.Greasing tube left end cap 112 is provided with fuel inlet neck 113, and high pressure hose 118 is docked with through hole on the greasing tube left end cap 112.Greasing tube right end cap 114 is provided with seal gease outlet connection 115, and the through hole on the greasing tube right end cap 114 is docked with greasing high pressure hose 117.
Preferably, also be communicated with by pressure release return hose 195 between hydraulic oil container 1 and the high pressure ram's horns 191, pressure release return hose 195 is provided with outlet Decompression valves 196 with high pressure ram's horns 191 junction.
Preferably, exhaust plug 116 is set on the sidewall of greasing tube 11.
Preferably, on the high pressure hose 192 that is communicated with high pressure ram's horns 191 and oil hydraulic pump 18, pressure gauge 194 is set.
Fig. 2 is with Fig. 1 for clarity sake and the structural representation that the abridged part all illustrates.Be connected by high pressure hose between the high pressure ram's horns 291 in high pressure ram's horns 191 in the first greasing external member and the second greasing external member, high pressure ram's horns 191 junction in this high pressure hose and the first greasing external member are provided with isolating valve 193.Oil hydraulic pump 18 and 28 in the first greasing external member and the second greasing external member is communicated with hydraulic oil container 1 by the low pressure oil inlet pipe respectively.Certainly, here just be communicated with that corresponding three the greasing tubes of oil hydraulic pump are example in two greasing external members and each the greasing external member with a hydraulic oil container, the utility model can also have a hydraulic oil container being communicated with the situation of other quantity greasing external members, but also the different situation of quantity of the greasing tube of oil hydraulic pump correspondence among greasing external member arbitrarily or the whole greasing external member can be arranged wherein.During greasing, can open, close corresponding needle valve 119,129,139 and isolating valve 193, realize that different modes such as one of a pump, one of two pump, two of two pumps inject according to the greasing needs.
Preferably, high-pressure grease pouring equipment of the present utility model also comprises the toolbox (not shown) that is arranged on the base (not shown), and the grease gun head of all kinds of models that common tool is complementary such as piston head return device shown in Figure 3 and dress fat device shown in Figure 4 and with various greasing service equipments, the greasing flexible pipe of supporting length are housed in the toolbox.
Preferably, oil hydraulic pump of the present utility model adopts hydraulic hand-pump, comprises Decompression valves 181, plunger 182 and handle 183, as shown in Figure 1.
At oil hydraulic pump is under the situation of hydraulic hand-pump, in conjunction with the greasing process high-pressure grease pouring equipment of the present utility model is described further.
Operator depress the oil hydraulic pump handle repeatedly, make hydraulic oil in the hydraulic oil container enter high pressure pipe joint and the piston forward that promotes in the greasing tube moves, and piston is then pushed the seal gease before the piston in the greasing tube.Because oil hydraulic pump is suppressed continuously, when piston end surface pressure surpassed greasing equipment installation pressure, seal gease then was squeezed in the sealed cavity of greasing service equipment, realizes the function of quick greasing.After finishing greasing, the Decompression valves by outlet Decompression valves and/or oil hydraulic pump unloads back hydraulic oil container with the hydraulic oil in the greasing wound packages oil pocket, so as not to the greasing high pressure hose when separating with the greasing service equipment with the grease gun head in the greasing wound packages fat chamber remaining seal gease spray.
It is to be noted, usually a pressure-relief valve with oil hydraulic pump unloads back hydraulic oil container with the hydraulic oil in the greasing wound packages oil pocket, under the more situation of hydraulic oil in greasing wound packages oil pocket, just use the common pressure release of Decompression valves of outlet Decompression valves and oil hydraulic pump, so that quick pressure releasing.
At this moment seal gease may need the seal gease of packing into repeatedly using up after the greasing operation in greasing wound packages fat chamber.At first, unload the end cap of greasing wound packages fat chamber one side, load onto piston head return device as shown in Figure 3, open Decompression valves and rotational lead screw handle, piston head is got back to the end caps of greasing wound packages oil pocket one side.Then, unload the piston head return device, change dress fat device as shown in Figure 4, put seal gease tube and firmly pushing away forward, thereby with the seal gease greasing tube of packing into.
Below, compare by the dress fat performance and the greasing performance of two forms high-pressure grease pouring equipment of the present utility model and present two kinds of greasing equipment using always:
The contrast table of three kinds of greasing device performance parameters (form 1)
By dress fat amount and the contrast of dress fat time, in the time, high-pressure grease pouring equipment dress fat amount of the present utility model is 20 times before transforming at same dress fat, and dress fat efficient obviously improves, and makes it to be more suitable for the field produces needs.
Three kinds of greasing equipment are to common valve and the contrast table of flange greasing operating time (form 2)
By the greasing operating time of shaft mouth test apparatus flap type, 160 flanges, 158 flanges, the 2-3 that can draw the high-pressure grease pouring equipment greasing operating time of the present utility model and be greasing speed before transforming doubly, significantly reduce operator's workload, reduced labor intensity.
The utility model need to from real field produces, combine the characteristics of multiple greasing instrument, the advantage such as have that dress fat amount is big, dress fat speed is fast, simple to operation, injection pressure is high and greasing is effective will have broad application prospects in oil field equipment maintaining industry.
