Technical field
The present invention relates to a kind of air heater that is used for motor, be applicable to large-size machine, when being specially adapted to the parking of large ship motor the motor internal air is heated, remove motor internal moisture, guarantee the motor safety reliability service.
Background technology
Boats and ships are used large-size machine, receive the influence of its working environment, and air ratio is moist in the motor; The insulaion resistance that is in this environment motor windings for a long time can descend, and motor can't normally move, for this reason; When motor stopped, the air heater of starter motor removed moisture usually; The assurance motor internal is dry, and the insulaion resistance of keeping motor is in normal range (NR).The prior art boats and ships are with the air heater of motor, and the semicircular in shape tubulose is installed along the electric machine stand bottom usually, and it is bigger that this structure takies the electric machine stand inner space, and dismounting is inconvenient, and it is inhomogeneous to inner air heat to be installed in the support bottom.So for a long time, people thirst for that a kind of easy disassembly is arranged, air heater little, that can guarantee motor even air heating along the circumferential direction takes up room.
Summary of the invention
The objective of the invention is to, overcome the shortcoming of prior art, a kind of easy disassembly is provided, is convenient to maintaining, little, the vibration proof of taking up room, anti-ly dabble, long service life, can guarantee the air heater of motor safety reliability service,
Technical scheme of the present invention is:
A kind of air heater that is used for motor comprises heating tube, sleeve, cover of heater and insulation board; Said heating tube is the spirality electric heating tube with metal tube shell, on the sleeve outer wall that at one end has cylinder base; Heating tube has two ports of export, passes cylinder base respectively and is welded into integral body in contact position and cylinder base; Connect an insulation board on the cylinder base, the port of export of heating tube stretches out insulation board, and the port of export has binding post; The cover of heater with wire hole that is used to protect the port of export and binding post is installed on the insulation board.
Further technical scheme is:
The described air heater that is used for motor, its binding post lean on the port of export place of heating tube to be set with the ceramic jacket that is used to make binding post and heating tube metal tube casing insulation.
The described air heater that is used for motor, its heating tube are also fixing with the welding of sleeve cylinder body outer wall.
It is to be fixedly connected through trip bolt that the described air heater that is used for motor, its cylinder base are connected with insulation board.
The described air heater that is used for motor, its cover of heater and insulation board are sealedly and fixedly connected.
The described air heater that is used for motor is useful on the lectrothermal alloy wire that makes the center and the high-temperature insulation filler of metal tube casing insulation in its heating tube metal tube shell.
The described air heater that is used for motor, the metal tube sheathing material of its cover of heater and sleeve and heating tube is corrosion-resistant metal materials, is selected from the 1Cr18Ni9Ti stainless steel, or the Tc4 titanium alloy; The material of insulation board is a high-temperature insulation material, is selected from fluoroplastics, or polyether-ether-ketone, or polyether sulfone; Described lectrothermal alloy wire is a Ni20Cr80 alloy silk.
In conjunction with structure of the present invention and principle, to remarkable result of the present invention explanation as:
Heating tube of the present invention is looped around on the sleeve twist, and exit portion is stretched out sleeve and in the outlet contact position the two formed integral body through welding, can make heating process not receive vibration influence; Dry in order to ensure the outlet part, through cover of heater that outlet is partially enclosed, conduct electricity between binding post, cover of heater and the sleeve for avoiding simultaneously, there is insulation board isolated between the three.Heating tube carries out spirality and bends, and can guarantee to send enough heats, makes shared space smaller again.Alloy-free silk in the heating tube outlet certain limit is drawn through bolt column, and the exit installs ceramic jacket additional and carries out isolated insulation.The present invention is simple and compact for structure, it is little to take up room, shock resistance good, be convenient to dismounting, is easy to safeguard.Be specially adapted to the inner air heating of large ship motor.When the large ship motor stops, need heat the motor internal air, the present invention can remove motor internal moisture well, keeps the motor windings insulaion resistance in normal range (NR), guarantees the motor safety reliability service.
Description of drawings
Fig. 1 is used for the air heater structural representation of motor for the present invention;
Fig. 2 is used for the heating tube sketch map of the air heater of motor for the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explain.
Like Fig. 1, shown in 2, a kind of air heater that is used for motor comprises heating tube 4, sleeve 3, cover of heater 1 and insulation board 2; Said heating tube 4 is for having the spirality electric heating tube of metal tube shell, on the sleeve that at one end has cylinder base 3.1 3 outer walls; Heating tube 4 has two ports of export 4.1, passes cylinder base 3.1 respectively and is welded into integral body in contact position and cylinder base 3.1; Connect an insulation board 2 on the cylinder base 3.1, the port of export 4.1 of heating tube 4 stretches out insulation board 2, and the port of export 4.1 has binding post 5; A cover of heater with wire hole 1 that is used to protect the port of export 4.1 and binding post 5 is installed on the insulation board 2.Described binding post 5 leans on the port of export 4.1 places of heating tube 4 to be set with the ceramic jacket 6 that is used to make binding post 5 and heating tube 4 metal tube casing insulations.Described heating tube 4 is also fixing with the welding of sleeve 3 cylinder body outer walls.It is to be fixedly connected through trip bolt 7 that cylinder base 3.1 is connected with insulation board 2.Described cover of heater 1 is sealedly and fixedly connected with insulation board 2.Be useful on the lectrothermal alloy wire that makes the center and the high-temperature insulation filler of metal tube casing insulation in the heating tube 4 metal tube shells.Cover of heater 1 is corrosion-resistant metal materials with the metal tube sheathing material of sleeve 3 and heating tube 4, is selected from the 1Cr18Ni9Ti stainless steel, or the Tc4 titanium alloy; The material of insulation board 2 is a high-temperature insulation material, is selected from fluoroplastics, or polyether-ether-ketone (PEEK), or polyether sulfone (PES); Lectrothermal alloy wire is a Ni20Cr80 alloy silk.
Cover of heater 1 of the present invention is processed by the corrosion resistant metal plate, can be in case the influence of maritime environment, and can corrosion.Cover of heater is used for mainly preventing that the heater binding post from making moist, and heater is stamped wire hole in addition, and the design attitude in lid hole will guarantee that also lead-out wire can not make moist.Insulation board 2 adopts high-temperature insulation material to make, and this insulation board is with binding post 5, sleeve 3 and cover of heater 1 insulation.Sleeve 3 also is to be made by corrosion-resistant metal materials, and it mainly is to be used for vibrationproof, through forming integral body with the heating tube local welding, avoids when work, damaging owing to the influence of vibrating causes heater.Heating tube 4 by Ni20Cr80 alloy silk, high-temperature insulation filler and corrosion resistant metal pipe shell, be that steel pipe is formed, through handling, form wholely, install ceramic jacket 9 insulation between binding post 5 and the heating tube 4 metal tube shells additional, protect binding post 5 and lectrothermal alloy wire.
Claim protection domain of the present invention is not limited to the foregoing description.
