Abstract
A simple automatic vacuum pump supply switch consists of a gas guide tube, an air pressure cavity shell, a rubber bowl, a contact switch shell, a power supply contact, a vacuum monitoring pressure contact and fixing bolts. The simple automatic vacuum pump supply switch is characterized in that the gas guide tube is arranged at one end of the air pressure cavity shell, the air pressure cavity shell and the contact switch shell are in opposite butt joint and are fixedly connected by a plurality of fixing bolts, the rubber bowl is fixed between the air pressure cavity shell and the contact switch shell in a sealing manner, the vacuum monitoring pressure contact is arranged outside the dome part of the rubber bowl, a sleeve is arranged at the central position of one end of the contact switch shell, and the power supply contact is fixedly installed inside the sleeve. The simple automatic vacuum pump supply switch has the beneficial effects of simplicity, practicability, low manufacturing cost and stable work performance.
Description
Technical field
The present invention relates to vacuum recloser field, be specifically related to vacuum make-up system recloser, for vacuum pump Automatic Provisioning System.
Background technique
Vacuum pump is that a kind of rotary positive-displacement vacuum pump must have fore pump to coordinate can to use and in wider pressure range, has larger pumping speed to contain dust and the insensitive industries such as metallurgy, chemical industry, food, electronics plated film that are widely used in of water vapor in being extracted gas.Two rotors of vacuum pump are by a pair of high class gear, to realize that it is relatively synchronous operated.Driving shaft connects with motor by coupling.At drive mechanism cloth, be set up and mainly contain following two kinds: first motor and gear are placed on the same side of rotor as figure.Driven rotor is passed in the past and is driven by motor terminal direct geared, and the torsional deflection of power rotor axle is little like this, and the gap between two rotors can not change greatly because of the torsional deflection of driving shaft, therefore make the gap between rotor even in operation process.The disadvantage of this kind of drive is: 1. on driving shaft, have three bearings, increased processing and the assembling difficulty of pump, also inconvenience of the dismounting of gear and adjustment; 2. overall structure unshapeliness, center of gravity deflection motor and gear-box one side of pump.The switch kind of mating with vacuum pump is more, but often cost is higher.
Summary of the invention
The object of the present invention is to provide a kind of vacuum make-up system or vacuum pump automatic makeup to Simple switch, there is beneficial effect simple and practical, cheap for manufacturing cost.
For achieving the above object, the present invention has adopted such technological scheme: described vacuum pump automatic makeup, to Simple switch, is comprised of air pipe, atmospheric pressure cavity shell, rubber bowl, contact-making switch shell, power contact head, vacuum monitoring pressure contact, fixing bolt; It is characterized in that, one end of atmospheric pressure cavity shell is provided with air pipe; Atmospheric pressure cavity shell docks in opposite directions with contact-making switch shell, and is connected and fixed by several fixing bolts, and between the two, sealing is fixed with rubber bowl, and the vault portion outside of rubber bowl is provided with vacuum monitoring pressure contact; The central position of one end of contact-making switch shell is provided with sleeve pipe, is mounted with power contact head in sleeve pipe.
Adopt after such structure, during vacuum pump work, make in atmospheric pressure cavity shell in vacuum state (air pressure for vacuum pump working state flows to as shown by arrows in FIG.); When vacuum state is in setting threshold, rubber bowl disconnects vacuum monitoring pressure contact and power contact head, stops the working state of vacuum pump; When vacuum state is not enough, while being in outside setting threshold, rubber bowl makes vacuum monitoring pressure contact contact with power contact head, makes vacuum pump in running order, all the time the vacuum pump vacuum hold mode in setting threshold automatically.Beneficial effect of the present invention is, simple and practical, cheap for manufacturing cost, stable work in work.
Accompanying drawing explanation
It shown in accompanying drawing, is the sectional view of concrete structure of the present invention.In figure, arrow is depicted as the air pressure flow direction of vacuum pump working state.
Embodiment
As shown in the figure, vacuum pump automatic makeup of the present invention, to Simple switch, is comprised of air pipe 1, atmospheric pressure cavity shell 2, rubber bowl 3, contact-making switch shell 4, power contact head 5, vacuum monitoring pressure contact 6, fixing bolt 7; It is characterized in that, one end of atmospheric pressure cavity shell 2 is provided with air pipe 1; Atmospheric pressure cavity shell 2 docks in opposite directions with contact-making switch shell 4, and is connected and fixed by several fixing bolts 7, and between the two, sealing is fixed with rubber bowl 3, and the vault portion outside of rubber bowl 3 is provided with vacuum monitoring pressure contact 6; The central position of one end of contact-making switch shell 4 is provided with sleeve pipe 40, is mounted with power contact head 5 in sleeve pipe 40.
