Description
Technical field
The utility model relates to the air pump energy saving device.
Background technique
The air pump working method is two kinds at present:
One, intermittent duty, when promptly gas tank air pressure reached setup pressure value, motor shut down, and air pump quits work; When air pressure is lower than setup pressure value, electric motor starting, air pump is reworked.This working method air pump motor is starting under very big load, and this just causes: 1. starting current is big, and the starting time is long, the easy excess load of motor, and when the adjustment setting pressure was too high, the electric motor starting difficulty caused burn-down of electric motor easily.2. air pump institute gas-distributing motor power causes waste greater than the rated power of air pump.3. mechanical shock was big when air pump moved, and was prone to make fastening piece and motor wiring pile bolt looseness, caused phase shortage to burn faults such as motor.
Two, continuously-running duty: the air pump that drives for the large-scale air pump that is difficult for frequent starting and heavy duty motor and the continuous drive manner that adopts, the air pump safety valve is opened exhaust when gas tank air pressure reaches setting value, to avoid overvoltage.Thereby cause: 1. continuous operation is at full load condition basically for the air pump motor, and efficient is low, and energy consumption is big.2. mechanical shock is big, and noise is big.3. the machine parts wearing and tearing are big, thereby maintenance period is shortened.
The model utility content
The utility model provides a kind of safe and simple air pump energy saving device, to reduce the electric motor starting electric current, reduces power consumption, reduces mechanical shock and noise, prolongs the working life and the maintenance period of air pump.
The utility model purpose is to realize like this; This air pump energy saving device comprises the one-way valve that is connected with air pump, and the one-way valve outlet is connected with relief valve and pressure relay in turn, pressure relay outlet termination gas holder; It is characterized in that the check valve inlet end is connected with auxiliary gas tank; Be connected with two position two-way valve between one-way valve and auxiliary gas tank, the two position two-way valve outlet end also is connected with overflow reduction valve and silencing apparatus in turn, and the auxiliary gas tank entrance point is connected with air pump through one-way valve.
The utility model discontinuous operation process and principle are:
At first the pressurized air of air pump generation gets into auxiliary gas tank 2 through one-way valve 1, and the pressure of auxiliary gas tank 2 is by 4 controls of overflow reduction valve.When auxiliary gas tank 2 gas storage pressures during greater than main gas holder 9 gas storage pressures, pressurized air through one-way valve 6 to main gas holder 9 inflations.Main gas holder 9 gas storage are pressed when reaching setting value; Pressure relay 8 breaks off; Air pump motor quits work; Simultaneously two position two-way valve 3 is opened, and the pressurized air in the auxiliary gas tank 2 outwards discharge through two position two-way valve 3, overflow reduction valve 4 and silencing apparatus 5 successively, and overflow reduction valve 4 cut out when the air pressure in auxiliary gas tank 2 equaled the pressure of overflow reduction valve 4 settings.And the pressurized air in the main gas holder 9 is not because the effect of one-way valve 6 can be through discharging with upper pathway.When main gas holder 9 internal air pressures were lower than setting value return difference value, pressure relay 8 was connected, and air pump motor starts, and two position two-way valve 3 is closed the above gas replenishment process to main gas holder 9 of repetition simultaneously.
When not having auxiliary gas tank 2 or during auxiliary gas tank 2 too little can not meeting the demands; Working procedure changes to some extent, and motor did not also reach rated speed when at first air pump was started working, in order to reduce to reach electric motor starting electric current and starting time purpose of energy saving; Two position two-way valve 3 unlatchings this moment; The pressurized air that air pump produces is successively through two position two-way valve 3, overflow reduction valve 4 and silencing apparatus 5 dischargings, thereby causes motor under idling lotus or very little load condition, to work, after time-delay a period of time when motor reach or during near rated speed two position two-way valve 3 close; The motor application of load, the pressurized air that air pump produces is inflated to main gas holder 9 through one-way valve 6.
In each air pump operation cycle, all be during electric motor starting in a word from the starting down of a very little load, the linear startup or No Load Start; To reduce starting time, reduce inrush current, thereby reduce energy consumption of electrical machinery; Reduce noise and mechanical shock, prolong air pump working life and maintenance period.
Continuous operation process and principle:
Start-up course is the same with intermittently used air pump principle; Difference is after main gas holder 9 pressure reach setting value; Two position two-way valve 3 is opened; The pressurized air that air pump produces is successively through two position two-way valve 3, overflow reduction valve 4 and silencing apparatus 5 dischargings; This moment the air pump motor operations idling carry or very low load condition under, two position two-way valve 3 is closed when main gas holder 9 pressure are lower than the return difference value of setting value, air pump application of load (then motor can linear application of load if any auxiliary air cylinder) work circulates so repeatedly.
After making air pump reach setting pressure in a word, motor operations under unloaded or very low loading condition, thereby reach purpose of energy saving.
The technological progress that the utility model is obtained: owing to take the utility model structure; Can realize that the air pump soft start is gentle is pressed onto the motor no-load running that reaches after the setting value, can reduce 2~3 seconds electric motor starting time with existing discontinuous operation pattern V-3.0/10 (join the 22KW motor and set working pressure 0.8MP) air pump comparison, can reduce inrush current 50%; The each startup of motor can reduce energy consumption of electrical machinery 50%; Can effectively reduce noise and mechanical shock, with V-3.0/10 relatively, can prolong air pump working life about 1/3; Prolong maintenance period 2 months, and can reach purpose of energy saving.
