Abstract
The utility model relates to an automatic feeding simple switch for a vacuum pump. The automatic feeding simple switch consists of a gas guide tube, an air pressure cavity shell, a rubber bowl, a touch switch shell, a power supply contactor, a vacuum monitoring pressure contactor and fixed bolts. The automatic feeding simple switch is characterized in that one end of the air pressure cavity shell is provided with the gas guide tube; the air pressure cavity shell and the touch switch shell are in abutting joint oppositely, and are connected and fixed through a plurality of fixed bolts, the rubber bowl is fixed between the air pressure cavity shell and the touch switch shell in a sealing manner, and the outer side of a dome portion of the rubber bowl is provided with the vacuum monitoring pressure contactor; a sleeve is arranged at the central position of one end of the touch switch shell, and the power supply contactor is arranged and fixed in the sleeve. The automatic feeding simple switch has the beneficial effects of being simple and practical, low in manufacturing cost, and stable in working performance.
Description
Technical field
The utility model relates to vacuum recloser field, is 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.
Model utility content
The purpose of this utility model is to provide a kind of vacuum make-up system or vacuum pump automatic makeup to Simple switch, has beneficial effect simple and practical, cheap for manufacturing cost.
For achieving the above object, the utility model 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.The beneficial effects of the utility model are, simple and practical, cheap for manufacturing cost, stable work in work.
Accompanying drawing explanation
It shown in accompanying drawing, is the sectional view of the utility model concrete structure.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 described in the utility model, 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.
