Abstract
The invention discloses an explosion-proof motor shell dehumidification machining technology, which comprises the following steps of: hoisting explosion-proof motor shell parts required to be assembled such as a base, an end cover, a bearing inner cover and the like onto a conveyor belt before a stator is installed in a shell, conveying the parts to a drying oven of 70 DEG C and drying for 2 hours, then conveying the parts to a cooling area and cooling to room temperature, and timely assembling the parts into an explosion-proof motor. The technology has the advantages that: because the moisture of the explosion-proof motor shell parts subjected to a static pressure test is removed, after assembly, the dryness in the explosion-proof motor is ensured, the problems that insulating materials are quickly aged, the insulating performance is reduced and the insulating materials are burnt due to high moisture in the conventional explosion-proof motor are solved, and the service life of the explosion-proof motor is prolonged.
Description
Technical field
The present invention relates to fire-proof motor processing technology field, particularly a kind of dehumidifying processing technology of fire-proof motor shell.
Background technology
Present fire-proof motor; Owing in the explosive type gaseous environment, use for a long time; So the shell of fire-proof motor should be able to effectively bear inner blast pressure, on the fire-proof motor structural design, these stop the part that internal explosion conducts outward to be called the flame proof part; National Specification, the flame proof part is accomplished in fine finishining, assembling must be done static pressure test before.To be water be pressed into the explosion-proof chamber of flame proof part, the qualified situation of inspection flame proof part in the pressure time of regulation through forcing press to static pressure test.Therefore, all wet behind these flame proof part static pressure tests.
Present production technology is: in process of production, with the fire-proof motor shell of doing behind the static pressure test, comprise that support and end cap install after owing to there is not dry mistake, the moisture in the casing is heavy, humidity is high.Because the moisture in the casing is heavy, humidity is high, thereby has caused the insulation resistance of fire-proof motor low.The performance of fire-proof motor insulating material directly receives Influence of Temperature, and after the fire-proof motor insulation resistance was low, fire-proof motor was at the operation adstante febre; Heat radiation is slow, temperature rise, and insulating material is aging to be accelerated, and insulation property significantly descend; The quality and the useful life of fire-proof motor have directly been had influence on; When serious, can cause insulating material to burn, fire-proof motor is scrapped immediately.
Summary of the invention
The dehumidifying processing technology that the purpose of this invention is to provide a kind of fire-proof motor shell through the oven dry to the fire-proof motor casing part, overcomes above-mentioned shortcoming of the prior art.
For realizing above-mentioned purpose, the present invention realizes through following technical scheme:
A kind of dehumidifying processing technology of fire-proof motor shell may further comprise the steps:
(1) prepare: before stator inlet case was installed, the fire-proof motor casing part with required assembling comprised parts such as support, end cap, internal bearing cover, and lifting is put on the conveyer belt, and the drying baker temperature is set at 70 ℃ simultaneously;
(2) transmit: start the conveyer belt motor, fire-proof motor casing part to be dried is sent to drying baker inside;
(3) oven dry: the inner oven dry of drying baker 2 hours;
(4) transmit: oven dry is started the conveyer belt motor after accomplishing, and the fire-proof motor casing part after the oven dry is sent to the drying baker outside;
(5) cooling: utilize the fire-proof motor casing part after lifting will be dried to hang lower conveyor belt, be cooled to room temperature in the cooling zone;
(6) assembling: cooled fire-proof motor casing part is transported to place to be assembled and installs.Should as early as possible install because of noting the fire-proof motor casing part after the oven dry this moment, prevents outside that the storage period is long and make moist once more.
The beneficial effect of the dehumidifying processing technology of fire-proof motor shell of the present invention is: owing to removed the moisture of explosion-proof motor housing part behind the static pressure test; After the assembling; Guaranteed the inner aridity of fire-proof motor; Prevented the problem that original fire-proof motor inside is aging soon because of the heavy insulating material that produces of moisture, insulation property reduce, insulating material burns, the useful life of having improved fire-proof motor.
Embodiment
A kind of dehumidifying processing technology of fire-proof motor shell may further comprise the steps:
(1) prepare: before stator inlet case was installed, the fire-proof motor casing part with required assembling comprised parts such as support, end cap, internal bearing cover, and lifting is put on the conveyer belt, and the drying baker temperature is set at 70 ℃ simultaneously;
(2) transmit: start the conveyer belt motor, fire-proof motor casing part to be dried is sent to drying baker inside;
(3) oven dry: the inner oven dry of drying baker 2 hours;
(4) transmit: oven dry is started the conveyer belt motor after accomplishing, and the fire-proof motor casing part after the oven dry is sent to the drying baker outside;
(5) cooling: utilize the fire-proof motor casing part after lifting will be dried to hang lower conveyor belt, be cooled to room temperature in the cooling zone;
(6) assembling: cooled fire-proof motor casing part is transported to place to be assembled and installs.
