Abstract
An air tightness testing device of a motor comprises a testing bench, wherein the testing bench is provided with an air cavity and an upper platform, a sealing cover is arranged on the upper platform, a connecting screw is arranged on the sealing cover, and an extending hole communicated with the air cavity is formed on the sealing cover; and the air cavity is communicated with a first air pipe and a second air pipe, and a pressure gauge is arranged on the first air pipe. The air tightness testing device of the motor can check the air tightness of the motor, thereby preventing the motor with unqualified air tightness from being used and avoiding damaging the motor.
Description
(1) technical field
The utility model relates to a kind of tightness test device of motor.
(2) background technology
Easy when motor is used to stir, the material of its stirring (especially gas) thus enter into the serviceable life that influences motor in the motor easily.Though be provided with packoff (generally being the form that oil sealing adds packing washer) in motor, how the sealing property of packoff but can't judge on earth, the test unit that does not also have a kind of impermeability that is specifically designed to motor to detect at present.
(3) summary of the invention
In view of the test unit that does not also have at present a kind of impermeability that is specifically designed to motor to detect, the utility model provides the tightness test device of the motor that a kind of impermeability that is specifically designed to motor detects.
The technical scheme in the invention for solving the technical problem is: a kind of tightness test device of motor, comprise testing table, described testing table has air cavity and upper mounting plate, described upper mounting plate is provided with gland bonnet, described gland bonnet is provided with connecting screw rod, offers the hole of stretching into described air cavity UNICOM on the gland bonnet; Described air cavity also with first tracheae and the second tracheae UNICOM, described first tracheae is provided with tensimeter.
The utility model in use, fixedly connected one connects end cap on the front end end cover of motor, on the end face that connects end cap groove is set, and is embedded in O-ring seal at groove.To connect the gland bonnet on the end cap alignment test platform platform then, the output shaft of motor stretches in the hole, and connecting screw rod passes the connection end cap, and is with set nut that the link cover lock is tight again.Inflate in air cavity by second tracheae then, the air pressure in gauge hand shows testing table stops its inflation is sealed second tracheae then when full.Through 30 minutes, gauge hand showed that air pressure does not have decline, represents that then the impermeability of motor is good, can pass through air-tight test.
The beneficial effects of the utility model are: can test to the impermeability of motor, thereby avoid the underproof motor of impermeability to use motor be caused damage.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of tightness test device of motor comprises testing table 1, described testing table 1 has air cavity and upper mounting plate 2, described upper mounting plate 2 is provided with gland bonnet 3, and described gland bonnet 3 is provided with connecting screw rod 4, offers the hole of stretching into described air cavity UNICOM on the gland bonnet 3; Described air cavity also with first tracheae 5 and second tracheae, 6 UNICOMs, described first tracheae 5 is provided with tensimeter 7.
The utility model in use, fixedly connected one connects end cap 9 on the front end end cover of motor 8, on the end face that connects end cap 9 groove is set, and is embedded in O-ring seal at groove.To connect the gland bonnet 3 on the end cap 9 alignment test platform platforms then, the output shaft of motor 8 stretches in the hole, and connecting screw rod 4 passes and connects end cap 9, will connect end cap 9 lockings with set nut again.Inflate in air cavity by second tracheae 6 then, the air pressure in tensimeter 7 pointers show testing table 1 stops its inflation when full, seals second tracheae 6 then.Through 30 minutes, the pointer of tensimeter 7 showed that air pressure does not have decline, represents that then the impermeability of motor is good, can pass through air-tight test.
Claims (1)
1. the tightness test device of a motor, it is characterized in that: comprise testing table, described testing table has air cavity and upper mounting plate, and described upper mounting plate is provided with gland bonnet, described gland bonnet is provided with connecting screw rod, offers the hole of stretching into described air cavity UNICOM on the gland bonnet;
Described air cavity also with first tracheae and the second tracheae UNICOM, described first tracheae is provided with tensimeter.
