Abstract
The utility model relates to an energy-saving reciprocation type vacuum pump. The energy-saving reciprocation type vacuum pump comprises a vacuum tank (1), a vacuum meter (2), a reciprocation type vacuum pump (3), a motor (4), a frequency converter (5), a programmable logic controller (6), valves (7 and 8), a conduction line (9), a wire (10) and a pipeline (11), wherein the vacuum meter monitors a vacuum amount in the vacuum tank; the conduction line transmits the vacuum amount to the programmable logic controller for controlling; the frequency converter converts a signal and adjusts the movement power of the reciprocation type vacuum pump based on the practical production need; at the beginning of the production, a low speed is adopted for operation, and the speed is increased gradually to reach to the speed needed by the production. The energy-saving reciprocation type vacuum pump achieves the effects of reducing abrasion of a sliding sheet efficiently, improving the practical service life of the sliding sheet, decreasing energy consumption and reducing current waste caused by long-time too-high current; the whole system adopts a split type design, so that great convenience is brought to replacement of easily damaged parts.
Description
Technical field
The utility model relates to a kind of energy-conservation reciprocating vacuum pump, and it is a kind ofly can by programmable logic controller (PLC), change the instrument of the motor operate power of reciprocating vacuum pump, belongs to field of vacuum.
Background technique
Reciprocating vacuum pump is as the capital equipment that obtains coarse vacuum, in China, had historical for many years, be mainly used in the production processes such as gas conveying, vacuum filtration, vacuum crystallization, because reciprocating vacuum pump is the to-and-fro motion in cylinder and vacuum by piston, so the adjusting of piston stop and the sealing of piston rod are the normal operation of reciprocating vacuum pump and vacuum key factor.
Traditional reciprocating vacuum pump, when operation, directly motor is increased to peak output, piston rod to-and-fro motion does not have progressive process, the serious wear that causes piston picture, cause loss economically, when changing piston slide plate, need to first pull down viewing window, then unclamp piston unt, with special spanner, pass through rotary-piston bar, regulate slide plate to be connected with piston rod, thereby the stop of regulating piston and cylinder neck, because pump intracorporeal space is less, therefore regulate comparatively trouble, because rod seal filler belongs to easily damaged parts, when the pump housing carries out long-time high load running, piston rod reciprocal time amount increases, be easy to make slide plate, stuffing box packing wearing and tearing or damage.Need frequent replacing, maintenance slide plate maintains the running of piston rod, and therefore maintenance bothers very much, and maintenance cost is high, and the time is long, affects working efficiency.
Model utility content
In order to solve the problem of above-mentioned existence, the utility model discloses a kind of energy-conservation reciprocating vacuum pump, this energy-conservation reciprocating vacuum pump, adopt vacuum measuring instrument to monitor the vacuum capacity in vacuum tank, by call wire, transmit vacuum capacity to programmable logic controller (PLC), control, by inverter converts signal, according to the needs of actual production, regulate the motion power of reciprocating vacuum pump, reduce the wearing and tearing of slide plate, improve the physical life of slide plate, whole system adopts split-type design, greatly facilitated the replacing of fragile part, this model utility also has the effect that reduces energy consumption to reduce electric current excessive for a long time simultaneously, the effect of waste.
A kind of energy-conservation reciprocating vacuum pump, its vacuum tank by three pipelines respectively with the external world, vacuum measuring instrument, reciprocating vacuum pump connects, vacuum tank is provided with valve with the extraneous pipeline being connected with reciprocating vacuum pump, and vacuum measuring instrument is connected with programmable logic controller by call wire, and programmable logic controller (PLC) is connected with frequency variator by electric wire, frequency variator is connected with motor by electric wire, and motor is connected with reciprocating vacuum pump.
Of the present utility model simple in structure, simple operation, in the process of work, when vacuum tank vacuum capacity tails off, be by vacuum measuring instrument, to transmit signal to arrive programmable logic controller (PLC) through call wire, programmable logic controller (PLC) is reacted and is acted on frequency variator by program, change signal by frequency variator is sent to above motor, motor acts on above reciprocating vacuum pump according to the adjusting of frequency variator, reciprocating vacuum pump starts there is low-speed motion, slowly accelerate to high-speed motion, reach gradually needed power requirements, then by pipeline be applied to vacuum tank above.Complete the working procedure of whole reciprocating vacuum pump.Because the working procedure of reciprocating vacuum pump is raise gradually by low speed, so the effect that the filler of reciprocating vacuum pump the inside and slide plate are played to a protection reduces the reciprocating vacuum pump needed energy consumption of high-intensity work always simultaneously.Improved greatly service life of equipment, also improved and changed slide plate for the infringement of equipment, this model utility also has the effect that the effect that reduces energy consumption reduces electric current excessive, waste for a long time simultaneously.
