Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Centrifuge in the present embodiment radiation heating quartz lamp, its structure as shown in Figure 3, comprises that fluorescent tube and two are the filament 1 that helical structure is wound around, fluorescent tube comprises lamp holder 4 and lamp wall 5; The wrapping wire cross section of every filament 1 is " U " shape, filament 1 wrapping wire is one-level around a circle, the adjacent 15 ° of layouts that are each other at different levels in wrapping wire cross section of every filament 1, each wrapping wire cross section a bit contacts with 5 three, lamp wall with bottom by 2, the upper end open place of " U " shape, as shown in Figure 5.
By experiment, the radiation heating quartz lamp of the centrifuge in the present embodiment, under rated voltage 220V condition, heating power can reach 2kW.Meanwhile, have certain high pressure and use ability, under 330V voltage conditions, its heating power exceedes 3.5kW, can make the thick steel drum of 2mm be heated to 1000 ℃.At acceleration, be in 80g centrifugal force environment, the centrifuge in the present embodiment can normally be worked more than 5min under rated voltage with radiation heating quartz lamp, more than heating power can guarantee to reach 2.1kW, can make the thick steel drum of 2mm be heated to 600 ℃.After work 5min, its filament axial deflection is minimum, can repeatedly use and does not damage.
For further improving the non-deformabilities such as filament, on the basis of embodiment 1, the position of filament 1 is fixedly improved.The inwall of described lamp wall 5 is with multiple inwardly protruded hemispheres 3, and double-stranded filament 1 is stuck in groove.
Conventional quartz lamp is because use procedure is static environment, and filament 1 does not stress, so only adopt lamp holder 2 to hold up filament 1 away from lamp wall 5.When the normal work of filament 1, filament 1 is at high temperature softening, easily under the effect vertically of inertia force to a Slideslip.Lamp wall 5 is designed to the structure with multiple groove surfaces, quartz lamp length in the present embodiment is 325mm, every 50mm, process the hemisphere 3 of a pair of internal projection, footpath is 2.5mm, because filament 1 adopts double-spiral structure, each wrapping wire cross section contacts a little with lamp wall 5, so the hemisphere 3 of internal projection can be blocked filament 1 location at an arbitrary position, make the axial deformation of filament 1 can only occur in the inside, zonule in 50mm, prevented the bulk deformation of filament 1.By improving filament 1 structure and filament 1 fixed form, design and meet the quartz lamp using in the centrifugal overload environment of high temperature, meet the instructions for use of hot centrifugal test.By centrifugal test, in the normal work of energising, acceleration is in 80g environment, quartz lamp after improvement is normally worked more than 5min, heating power exceedes 2kW, can realize all kinds of heating curves control, can meet the demand for heat of transshipping under environment in comprehensive Centrifugal Environment test.
In the present embodiment, the improvement of quartz lamp be can be used for to different length equally, the improvement of the quartz lamp of different capacity.
On the basis of embodiment 1, increase the adjacent angles each other at different levels in wrapping wire cross section of every filament 1, filament density reduces, and non-deformability improves, and all can guarantee that in 220V and 80g centrifugal force environment, normal work 5min is above indeformable; But because power declines gradually, need more heating time and cause experimentation to extend.
Adjacent at different levels while being arranged as each other 25 ° when the wrapping wire cross section of every filament 1, filament 1 power can reach 1900W left and right; Adjacent at different levels while being arranged as each other 35 ° when the wrapping wire cross section of every filament 1, filament 1 power can reach 1650W left and right; Adjacent at different levels while being arranged as each other 45 ° when the wrapping wire cross section of every filament 1, filament 1 power can reach 1500W left and right, now can meet the demand for heat of transshipping under environment in comprehensive Centrifugal Environment test.But when the rated power of filament 1 is less than 1500W, because power is too low, will cause quartz lamp cannot meet the demand for heat of transshipping under environment in comprehensive Centrifugal Environment test.
On the basis of embodiment 1, reduce the adjacent angles each other at different levels in wrapping wire cross section of every filament 1, filament 1 density improves, and power improves gradually, can meet the demand for heat of transshipping under environment in comprehensive Centrifugal Environment test; But because power is too high, cause its non-deformability to reduce, in 220V and 80g centrifugal force environment, the time of normal work shortens gradually, while working long hours, easily damages, and what impact was tested normally carries out.
Adjacent at different levels while being arranged as each other 10 ° when the wrapping wire cross section of every filament 1, filament 1 power can reach 2400W left and right, in 220V and 80g centrifugal force environment, can keep more than 5min indeformable during normal work; Adjacent at different levels while being arranged as each other 5 ° when the wrapping wire cross section of every filament 1, filament 1 power reaches 2700W left and right, in 220V and 80g centrifugal force environment, can keep 5min indeformable during normal work.But adjacent at different levels while continuing to reduce each other when the wrapping wire cross section of filament 1, although can meet the demand for heat of transshipping under environment in comprehensive Centrifugal Environment test, because filament 1 easily be out of shape, can cause quartz lamp to damage, affect to test and carry out.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model the utility model.If these are revised and within modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these changes and modification interior.
