Abstract
A water jacket structure capable of preventing bulging of a water cooling motor relates to a water cooling motor. In the water jacket structure capable of preventing bulging of the water cooling motor, an inner water jacket and an outer water jacket are sleeved together, and a middle cavity is a water accommodating space. The water jacket structure capable of preventing bulging of the water cooling motor is characterized in that the side surface of the outer water jacket is equipped with a through hole, and the inner and outer water jackets are fixedly connected at the through hole position. By using the water jacket structure capable of preventing bulging of the water cooling motor, the connection intensity of the inner and outer water jackets can be improved, a bulging phenomenon can be prevented from generating effectively, and the product service life can be improved.
Description
Technical field
The utility model relates to a kind of water-cooled machine, especially a kind of water jacket that more is applicable to the water-cooled machine of coal mine working environment.
Background technology
Water-cooled machine is to utilize the motor of water as heat eliminating medium, though the structure more complicated, radiating effect is better, so under a lot of adverse circumstances, be able to use colliery for example.
Existing water-cooled machine all contains water jacket, and described water jacket two-layerly is made up of inside and outside, and the centre has cavity to be used for the cooling water that flows.For this type water-cooled machine, the cooling water inlet pressure maximum of general provision is not more than 3MPa.But, in the Coal Production of reality,, be the common occurrence feelings so hydraulic pressure exceeds standard owing to be in negative height above sea level state under the coal mine, the too high meeting of cooling water pressure causes outer water jacket bulging.In addition because the mine quality problem, cause obstruction same can build-up of pressure too high and bulging.In case outer water jacket bulging, the water channel short circuit, motor just can not work on, and the dismounting of the motor after bulging ten minutes difficulty, even will employ the thermoelectricity weldering, and this is very dangerous in the down-hole, much under the situation all is rocking arm to be cut off a liter top handle.Cause coal-winning machine to be scrapped, lose huge.
The utility model content
The purpose of the utility model is the shortcoming for the jacket structure for water that overcomes the described existing water-cooled machine of background technology, invents a kind of jacket structure for water that can effectively overcome the water-cooled machine of bulging.
For reaching above-mentioned purpose, the technical scheme that the utility model is taked is:
Inner water sleeve is nested with outer water jacket is in the same place, and it is water space capacity that there is cavity the centre, it is characterized in that: the side of outer water jacket is provided with through hole, and inside and outside water jacket has fixed connection in the through hole.
Connected mode can adopt welding fixing.
The through hole of the utility model through being provided with on the water jacket outside; And use welding method that inside and outside water jacket is linked into an integrated entity, set up a separatist regime by force of arms inner cavity scope, reduced the gathering of pressure; And the welding through through hole; Improved the bonding strength of inside and outside water jacket, the factor of two aspects can effectively prevent the generation of bulging phenomenon, improves the useful life of product.
Figure of description
Fig. 1, the partial view of the structure of the utility model.
Embodiment
Like the jacket structure for water of the water-cooled machine of Fig. 1, water jacket is made up of inner water sleeve 1 and outer water jacket 2, and both are socketed into water jacket integral body, and the centre is a cavity 3, and cavity is the space of cooling water.The side of water jacket 2 has several through holes 4 outside, adopts the mode of welding that inside and outside water jacket is linked together through through hole.Through hole 4 positions will form a column dowel, play and improve intensity and the effect that reduces internal pressure, prevent bulging.
Claims (1)
1. jacket structure for water that can prevent the water-cooled machine of bulging, inner water sleeve is nested with outer water jacket, and water space capacity is left in the centre, it is characterized in that: said outer water jacket side is provided with through hole, and inside and outside water jacket has fixed connection in the through hole.
