Be that the utility model adjoint is described in further detail below:
Embodiment 1: referring to Fig. 1, Fig. 2 and shown in Figure 6, this is the warning device of installing on a kind of mechanical, electrical two filters of posting a letter, side assembling oil cylinder 3 in the shell 15, assembling has the piston 1 and the spring 4 of magnet steel in the oil cylinder 3, oil cylinder 3 one ends have the oil pressure P2 inlet behind the filter medium, and the elasticity indication cap 5 that the indication of opposite side make-up machinery is reported to the police in the shell 15 is under the reset condition, indicate cap 5 and have between the magnet steel piston 1 an aluminium interlayer every 0.8 millimeter.Pressure oil P1 entered the mouth before shell 15 1 sides were provided with filter medium, whole mechanical contamination warning device, be assemblied on the filter end cap 2 with shell 15 and seal ring 19, see shown in Figure 6, on filter end cap 2, assembling the electricity polluting device of posting a letter again is characteristics of the present utility model, this electricity transmitting device only is made up of the socket latch 13 that has dry reed-pipe 8, being screwed into different depth with screw thread is assemblied on the end cap 2, be convenient to adjust the reset condition position of dry reed-pipe 8 and magnet steel piston 1, shown in Figure 1 be dry reed-pipe 8 in magnet steel piston 1 the place ahead (left side), dry reed-pipe 8 is in normally open.Shown in Figure 2 be dry reed-pipe 8 at piston 1 rear (the right), dry reed-pipe 8 is in normally off, dry reed-pipe 8 is formed loops with auxiliary reclay 9 and power supply 7, makes the tutorial light 6(of series connection or adopts electric bell or language alarm) and break contact 10 be in off state.
Whole working principle is like this: dry reed-pipe 8 is as electric switch, when magnet steel induced action and disappearance, dry reed-pipe 8 is in conducting and off state, the warning work thereby the realization electricity is posted a letter, this electricity warning device of posting a letter is assemblied in machinery and posts a letter on the warning device, realize mechanical, electrical two function of posting a letter and reporting to the police simultaneously.Because blocking the back fluid resistance, the contaminated particle of filter element increases, make the preceding pressure P 1 of filter core medium greater than the pressure P behind the filter medium 2, promptly produce a pressure difference △ P, with this pressure difference △ P is power, the piston 1 that promotion has magnet steel moves to dry reed-pipe 8 directions, see Fig. 1 and shown in Figure 6, or away from dry reed-pipe 8 directions, see shown in Figure 2, when piston 1 move H apart from the time, indication cap 5 magnetic induction amounts fade away, ejected by the spring below self, send the mechanical contamination alarm signal, simultaneously again because of the mobile H distance of piston 1, dry reed-pipe 8 is subjected to magnetic induction effect adhesive, sends the electropollution alarm signal.For the control that piston 1 moves the H distance, be the load force P=△ PD that comes balance pressure difference △ P to be produced by spring 4
2/ 4 π change spring 4 rigidity and just can adjust the H distance.Working principle shown in Figure 2 is the same, is that normally closed dry reed-pipe 8 moves H apart from the back disconnection at piston 1, makes auxiliary reclay 9 outages, break contact 10 is set back by disconnection, tutorial light 6 sends electropollution and reports to the police, and has adopted PC on filter equipment, then can not use auxiliary reclay.
Embodiment 2: see Fig. 3 and shown in Figure 7, the piston 1, spring 4 and the oil cylinder 3 usefulness seal rings 19 that have annular magnetic steel 11 are assemblied in the shell 15, for make dry reed-pipe 8 in piston 1 normal phase to mobile working, the installation cavity 14 of a sealing of assembling in piston 1, whole cylinder 3 assembled are on shell 15; Shell 15 usefulness seal rings 19 are assemblied on the end cap 2 with thread forms, the socket latch 13 that has dry reed-pipe 8 is assemblied in shell 15 ends with thread forms, it is screwed into the original relative position of whole dry reed-pipe 8 of depth-adjustment and magnet steel, and whole working principle is described with embodiment 1.
Referring to Fig. 4 and shown in Figure 8, same as above substantially, just P1 and P2 oil power oil-in commutation, thus changed spring 4 corresponding positions, and the relative position of dry reed-pipe and annular magnetic steel 11, whole working principle is ditto described.
Referring to Fig. 5 and shown in Figure 9, substantially with Fig. 3 and shown in Figure 7, just annular magnetic steel 11 is used the cylindricality magnet steel instead, piston 1 changes cylindricality into by blind hole, and dry reed-pipe 8 is to improve dry reed-pipe 8 work magnetic induction sensitivity in a side of piston 1 same axis, install the induction iron of making of pure iron or magnetically soft alloy 16 additional at dry reed-pipe 8 front ends, also fixed simultaneously dry reed-pipe 8, assembling one isolation layer 18 between induction iron 16 and the shell 15, induction iron 16 front ends assembling spacer 17 is adjusted magnetic intensity.Whole working principle is ditto described, and dry reed-pipe 8 reset conditions are in normally closed.
Embodiment 3: the foregoing description 1 and embodiment 2 are assemblied in the utility model on the filter end cap 2.Also can be assemblied on the filter urceolus, also can be assembled into the independent plank frame element of a cover, be assemblied on filter end cap or the urceolus with screw again and on other position.
The utility model has the advantages that:
1, the pollition warning system size of components is little, and is in light weight, do not increase filter volume and weight, enlarged the scope at the position that filter is installed, and reduced filter and taken up space in equipment installation institute.
2, more improve warning sensitivity for two warning devices of posting a letter, avoided the disadvantage of the single function alarm error of posting a letter, improved the filter core utilization rate, simultaneously two kinds of signals Check and correction remedies mutually mutually, and the operation and maintenance staff is discovered easily, improves the reliability and stability of warning work.
3, for electric single-shot letter warning device, because compact conformation, part is concentrated, and has more alleviated original volume, has improved the pollution warning sensitivity, the reliability and stability of work. Product has more Suresh Kumar, can satisfy the instructions for use of various filter different structures, and Shape Modelling is easier in exquisite future development attractive in appearance.
4, the warning device because employing screw-in electricity is posted a letter, can be according to the different home position duties that change of situation, having overcome simultaneously former machinery reports to the police in the shortcoming of judder, easy generation misoperation when shaking, so make the possibility of the oriented aerospace applications future development of the utility model.
