Background technology
Vavuum pump is a kind of mechanical device of making vacuum, and it can be discharged space airtight or semi-hermetic a Air or absorb, and reaches the relative vacuum of local space.Vavuum pump is widely used in the fields such as plastics machinery, pesticide chemical, dye chemical industry, tile machinery, Cryo Equipment, papermaking equipment, medication chemistry, food machinery, industrial furnace, electron trade, vacuum equipment, chemical fertilizer, metallurgy, oil, mine, ground processing.
Common vavuum pump has the kinds such as reciprocating vacuum pump, water ring pump, molecular pump, rotary-vane vaccum pump, piston type vacuum pump, swing piston type vacuum pump, diaphragm-type vacuum pump, linear vacuum pump.
When medicine and chemical industry use vavuum pump, because the diversity of the medium that contacts has often been brought a lot of problems to the use of vavuum pump.Cause the abnormal reason of vacuum system work to have a variety of, but the most common problem is often owing to contacted the relatively material of thickness, and the accumulation of sticky material in pump housing, add sticky material under long hot environment, shone into very large efficient for the running of mechanical device and lowered.In the use procedure of intermittently used vavuum pump, after the shutdown, the after-tack medium that condensation is got off is adsorbed on the inner chamber of pawl pump, and next time, load was larger during start when starting, sometimes even can not start.
Vavuum pump uses in chemical industry and pharmaceuticals industry, and domestic market does not have the system of automatic cleaning function selective substantially, because feed blocking causes the very big inconvenience of operation and efficient lower.Sometimes even will take machine apart and clean, waste time and energy.Simultaneously, the medium that chemical industry extracts has corrosivity mostly, sticks to for a long time the vavuum pump inner chamber, can cause pump chamber inner anticorrosioning coating (tetrafluoro coating) to break away from inner chamber, the aggravation corrosion, therefore, adopt effectively corrosion mitigation of automatic cleaning function, thereby prolong service life of vacuum pump.
The utility model content
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of easy to use, parameter is adjustable, pulse Vacuum pump automatic cleaning system that can fine maintenance motor.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of pulse Vacuum pump automatic cleaning system, comprise that vavuum pump assembly, cleansing medium reclaim stop valve, produce medium recovery stop valve, nitrogen stop valve, steam stop valve, vacuum gas equipment stop valve, check-valves, described vavuum pump assembly is provided with air entry and exhaust outlet, described cleansing medium reclaims stop valve and produces medium recovery stop valve and is connected with exhaust outlet, and described nitrogen stop valve, steam stop valve, vacuum gas equipment stop valve are connected with air entry.
Described air entry and exhaust outlet are located at respectively the both sides of vavuum pump assembly.
Described cleansing medium recovery stop valve and production medium reclaim the stop valve parallel connection and are connected with exhaust outlet through pipeline.
Described nitrogen stop valve, steam stop valve, vacuum gas equipment stop valve are in parallel and be connected with air entry through pipeline, and described check-valves and vacuum gas equipment stop valve are connected in series.
Automatic cleaning principle of the present utility model is the intermittence in system works, or motor is before stopping, automatic control system will be carried out the action of series and clean the residual material that may exist in the pump housing, the vavuum pump inner chamber is cleaned thoroughly, open again the nitrogen stop valve after the cleaning, the automatic blow-dry inner chamber reaches maintenance vavuum pump and the good operating state that keeps vacuum system.Guarantee that vacuum pump system started in next time, can promptly reach desirable duty.
Compared with prior art, the utlity model has following advantage:
(1) easy to use: controller is opened automatic cleaning function automatically according to operating mode, need not manually-operated, alleviates operating personnel's burden.
(2) parameter is adjustable: the parameter that can arrange has the automatic cleaning function of shutdown, stream time, and scavenging period, steam washing time, nitrogen dry up the time again, frequency converter frequency, steam flush mode, cleansing medium reclaim function when cleaning, and operating personnel can arrange different parameters at menu and come practical requirement.
(3) medium that cleans can be regulated according to different operating modes, and our specific aqueous media of using comprises steam in this invention, alcoholic medium, and organic solvent, or steam and Organic Alcohol, steam and organic solvent class are incorporated into the cleaning way of horizontal pulse formula; The medium that cleans can be regulated pH increases cleaning efficiency, and pH scope commonly used can be decided according to operating mode, and the pH value is at 0-12 usually.
(4) medium reclaims function, has special-purpose medium to reclaim valve, can reuse raw material, avoids waste, and economizes in raw materials.
Frequency converter frequency can be regulated as required when (5) cleaning.
(6) etching problem of minimizing vavuum pump inner chamber adopts automatic flushing device, can in time wash the medium of corrosion, prolongs the service life of vavuum pump.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1 for cleansing medium reclaim stop valve, 2 for produce medium reclaim stop valve, 3 be the vavuum pump assembly, 4 for the nitrogen stop valve, 5 for the steam stop valve, 6 for vacuum gas equipment stop valve, 7 be check-valves.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of pulse Vacuum pump automatic cleaning system, its structure as shown in Figure 1, this system comprises that cleansing medium reclaims stop valve 1, produce medium and reclaim stop valve 2, vavuum pump assembly 3, nitrogen stop valve 4, steam stop valve 5, vacuum gas equipment stop valve 6, check-valves 7, the both sides of vavuum pump assembly 3 are respectively equipped with air entry and exhaust outlet, cleansing medium recovery stop valve 1 and production medium reclaim stop valve 2 parallel connections and are connected with exhaust outlet through pipeline, nitrogen stop valve 4, steam stop valve 5, vacuum gas equipment stop valve 6 is in parallel and be connected with air entry through pipeline, and check-valves 7 and vacuum gas equipment stop valve 6 are connected in series.
