Advantage of the utility model and positively effect are:
1. the utility model has adopted double-deck water jacket structure, will advance, backwater separates effectively, can water coolant be cooled off major axis in the very first time, reached good cooling performance, makes major axis in vacuum environment, can be for a long time works better at high temperature.
2. the utility model has solved outer water jacket works better in vacuum, hot environment for a long time and since its water coolant can be earlier directly the hot spot of arrival parts cool off, make mechanism's good cooling results, and easy to process.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein: 1 is first axle head, and 2 is outer tube, and 3 is middle pipe, and 4 is interior pipe, and 5 is second axle head, and 6 is water inlet tap, and 7 is the backwater mouth, and 8 is through hole, and 9 is water entry, and 10 is backwater channel, and 11 is inner pipe passway.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to detail.
As shown in Figure 1; The utility model is inside and outside double-deck water jacket; Have water entry 9 and backwater channel 10 double-deck cooling spaces, water inlet tap 6 and backwater mouth 7 are connected with water entry 9 and backwater channel 10 respectively, said water entry 9 and backwater channel 10 coaxial settings, at one end are connected.The water jacket of the utility model comprises outer tube 2, middle pipe 3 and the interior pipe 4 that ecto-entad sets gradually; Outer tube 2, middle pipe 3 and the 4 coaxial settings of interior pipe; An end of pipe 4 was welded with first axle head 1 in outer tube 2, middle pipe 3 reached, and the other end is welded with the two ends welding post-treatment sealed at both ends position of second axle head, 5, the first axle heads 1 and second axle head 5 and outer tube 2, middle pipe 3 and interior pipe 4; Promptly inwardly be provided with interior concave space respectively vertically on first axle head 1 and second axle head 5; Two indent spaces are connected with inner pipe passway 11 respectively, in two interior concave spaces, dynamic seal mechanism can be installed, and can guarantee the vacuum tightness of vacuum apparatus; In inner pipe passway 11, place major axis, about major axis can be done, operation such as rotation in inner pipe passway 11.
Space between outer tube 2 and the middle pipe 3 is a backwater channel 10; Space between middle pipe 3 and the interior pipe 4 is a water entry 9; Water inlet tap 6 is fixed on outer tube 2 and the middle pipe 3, and backwater mouth 7 is fixed on the outer tube 2, near first axle head 1; Water inlet tap 6 is communicated with water entry 9, and backwater mouth 7 is communicated with backwater channel 10.Water inlet tap 6 and backwater mouth 7 are symmetrical set with outer tube 2 axial cross section central axis, and the extended line of the central axis of the central axis of water inlet tap 6 and backwater mouth 7 passes through the central axis of outer tube 2 respectively, and perpendicular to the central axis of outer tube 2.Circumferentially be evenly equipped with at middle pipe 3 that a plurality of confessions are advanced, the through hole 8 of backwater conversion near the tube wall of second axle head 5, this through hole 8 connects water entrys 9 and backwater channels 10.
The principle of work of the utility model is:
