Description
Technical field:
This utility model relates to glue and produces equipment and facilities, is specifically related to a kind of Multifunctional self-protector for vacuum pump.
Background technology:
The mechanical type oil-sealed vacuum pump manufactured by prior art, its gas circuit end and oil circuit top are all to be immersed in pumping fluid
In, oil circuit and gas circuit is the most uncontrolled once shuts down, pumping fluid will be returned in suction vacuum pump cylinder by oil circuit and gas circuit, has
Time be even drawn onto be not allow for absolutely pumping fluid and exist fine vacuum, in ultra high vacuum container.In vacuum technique, by this existing
As being referred to as " returning oil ".
Return the vacuum pump of oil, the most accurate pump kind rotary-vane vaccum pump, when again starting, have additionally time also
Two kinds of faults produce: one is to return oil can significantly increase the rotary inertia of rotor-support-foundation system, makes the starting performance of complete machine deteriorate, i.e. exists
In the time of regulation, complete machine does not reaches rated speed, time serious, drives motor just often to burn because of current overload；Two is to rotate
The rotor-support-foundation system that inertia increases, when by the driving by force of high pulling torque motor, relevant parts and components will increase mechanical load,
When load exceedes the allowable value about parts and components, the damage of multiple key components the most often occurs, scraps, or complete machine stall, i.e. " embrace
Car ", motor overload even occurs and the serious accident such as burns, in order to solve above-mentioned technical problem, special propose a kind of new technology
Scheme.
Utility model content:
The purpose of this utility model is the weak point in order to overcome above-mentioned prior art to exist, and provides a kind of vacuum pump
Multifunctional self-protector, it is easy to use, simple to operate, be prone to large-scale promotion application.
The technical solution adopted in the utility model is: a kind of Multifunctional self-protector for vacuum pump, including the pump housing, connects gas
Pipe, air inlet and cylinder, pump body is provided with cylinder, and cylinder is connected with air inlet, and air inlet is connected with trachea, cylinder and work
Being provided with movable block between plug cylinder, be provided with appendix, be connected with piston bottom appendix inside movable block, piston exports with motor
Axle connects, and piston cylinder sidewall is provided with air vent, and air vent is connected with air cavity, and air cavity lateral wall is provided with block, block and spring
One end connects, and the spring other end is connected with pull bar, and pull bar is connected with plugging block, and plugging block is connected with mobile bar.
Being provided with discharge port bottom the described pump housing, discharge port is provided with electromagnetic valve, and electromagnetic valve is with controller by wire even
Connecing, controller is connected by wire with touch sensor, and controller is connected by wire with power supply.
The beneficial effects of the utility model are: can find occur returning oil inside piston cylinder the very first time by this device existing
As, and processed in time returning oil phenomenon by controller, it is to avoid the damage of vacuum pump.
Accompanying drawing illustrates:
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model discharge port partial enlarged drawing.
Fig. 3 is this utility model air vent partial enlarged drawing.
Detailed description of the invention:
With reference to each figure, a kind of Multifunctional self-protector for vacuum pump, including the pump housing 9, trachea 1, air inlet 2 and cylinder 3,
The pump housing 9 is internal is provided with cylinder 3, and cylinder 3 is connected with air inlet 2, and air inlet 2 is connected with trachea 1, between cylinder 3 and piston cylinder 5
Being provided with movable block 8, movable block 8 is internal is provided with appendix 4, is connected with piston 5, piston 5 and motor output shaft bottom appendix 4
7 connect, and piston cylinder 6 sidewall is provided with air vent 14, and air vent 14 is connected with air cavity 20, and air cavity 20 lateral wall is provided with block 18,
Block 18 is connected with spring 17 one end, and spring 17 other end is connected with pull bar 15, and pull bar 15 is connected with plugging block 16, plugging block 16
It is connected with mobile bar 19.
Being provided with discharge port 12 bottom the described pump housing 9, discharge port 12 is provided with electromagnetic valve 11, electromagnetic valve 11 and controller 12
Being connected by wire, controller 12 is connected by wire with touch sensor 10, and controller 12 is connected by wire with power supply.
Specific implementation process is as follows: when oil phenomenon occurs returning in vacuum pump, oil can enter from air vent 14 or air inlet 2
Entering, no matter enter from air vent 14 or air inlet 2, it is internal that oil all can flow ultimately into piston cylinder 6, due to discharge port 12
Bottom the pump housing 9, owing to the effect oil of gravity can arrive discharge port 12 position, when oil contacts with touch sensor 10, connect
Touching sensor 10 and transmit a signal to controller 13, controller 13 controls electromagnetic valve 11 and opens, and at this moment oil will be from discharge port 12
Middle releasing, after releasing, oil does not contacts with touch sensor 10, and controller 13 controls electromagnetic valve 11 and cuts out, at this moment piston
Cylinder 6 is internal would not the appearance returning oil phenomenon, makes vacuum pump obtain good protection.
Can find that piston cylinder 6 is internal the very first time by this device to occur returning oil phenomenon, and by controller 13 to returning
Oil phenomenon processes in time, it is to avoid the damage of vacuum pump.
