Abstract
The utility model belongs to the dentistry complex treatment is the intake system field for the chair, concretely relates to electronic intake system of frequency conversion control dentistry, including vacuum pump and vapour and liquid separator, the last pressure transmitter that installs of vapour and liquid separator, the vacuum pump connection converter, pressure transmitter and converter all are connected with control system. The utility model discloses an adopt converter and pressure transmitter assorted mode, can carry out the comparison with settlement vacuum value with the vacuum value of pressure transmitter measuring dentistry complex treatment system to through the rotational speed of converter change vacuum pump, with the needs that satisfy dentistry complex treatment chair, can play energy -conserving effect using low ebb phase reduction power consumption, can ensure to use the normal work of peak period again.
Description
Technical field
This utility model relates to a kind of VFC dentistry motorized pumping systems, belongs to dental comprehensive therapeutic chair suction system field。
Background technology
In dental care process, the cooling water of turbine hand machine ejection is hoarded in the oral cavity with saliva, allows patient produce swallowing reflex, and oral cavity inner cooling water and saliva are spued by needs of patients so that diagnosis and treatment are interrupted。Meanwhile, the water smoke that the cooling water of turbine hand machine ejection produces spreads in consulting room, causes secondary pollution。Present doctor selects dentistry motorized pumping systems cooling water, saliva, water smoke to be taken away mostly。But no matter be stomatological hospital or Outpatient Service Stomatology, before just having gone to work morning and having come off duty afternoon, dentistry motorized pumping systems utilization rate is low, at 10 in the morning and afternoon, 3 dentistry motorized pumping systems utilization rates were high, how to match dentistry motorized pumping systems and annoying user always。Apolegamy low-power equipment, uses peak period, and suction force is substantially not enough, cannot meet user's request；Select powerful device, equipment running at full capacity, for meeting the demand of dental comprehensive therapeutic, it is typically on dentistry motorized pumping systems and mechanical relief valve is installed, use the low ebb phase, open mechanical type relief valve and supplement air, to meet the demand of dental comprehensive therapeutic, now set noise is big, and machine service life is short and power consumption is high。For meeting demand, most of users have to take the second best, and select powerful device。
In view of the above circumstances, occur in that the mode that apolegamy multiple stage weak machine combination uses at present, using the low ebb phase, patient is concentrated and is arranged in the clinic using same dentistry motorized pumping systems。But, the mode of several weak machine combinations needs hospital to arrange doctor's watch bill, brings inconvenience to hospital。
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of VFC dentistry motorized pumping systems, on the one hand, the low ebb phase can be used at dentistry motorized pumping systems, power consumption is low, on the other hand, it is possible to use peak period to meet user's request at dentistry motorized pumping systems, and do not affect doctor's normal operation。
VFC dentistry motorized pumping systems described in the utility model, including vacuum pump and gas-liquid separator, gas-liquid separator is installed pressure transmitter, and vacuum pump connects converter, and pressure transmitter and converter are all connected with control system。
This utility model adopts the mode that converter and pressure transmitter match, and increases converter and pressure transmitter on dentistry motorized pumping systems。By pressure transmitter, one vacuum that disclosure satisfy that dental comprehensive therapeutic chair is set, the vacuum degree of pressure transmitter measurement is compared with setting vacuum degree, and the rotating speed of vacuum pump is changed by converter, reduce or the purpose of Raise vacuum degree, to meet the needs of dental comprehensive therapeutic chair。Using the low ebb phase, vacuum pump rotating speed is slow, and aspiration is little, and capacity is little, it is not necessary to mechanical valve is opened, and noise is low, and power consumption is low；Using peak period, vacuum pump rotating speed is fast, it is possible to meet user's request。
The dentistry motorized pumping systems caused for avoiding pressure transmitter to damage is out of service, sets up the forced service switch that a control converter is opened, force vacuum pump work on dentistry motorized pumping systems。Guan Bi forced service button, can make vacuum pump in the constant operation of setting speed, meet user's request。
This utility model is compared with prior art had the beneficial effect that
The mode that this utility model matches by adopting converter and pressure transmitter, the vacuum degree of the dental comprehensive therapeutic system of pressure transmitter measurement can be compared with setting vacuum degree, and the rotating speed of vacuum pump is changed by converter, to meet the needs of dental comprehensive therapeutic chair, the low ebb phase can used to reduce power consumption, play energy-saving effect, can ensure that again the normal operation using peak period。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model。
In figure: 1, vacuum pump；2, gas-liquid separator；3, pressure transmitter；4, converter；5, system is controlled；6, forced service switch。
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, VFC dentistry motorized pumping systems described in the utility model includes vacuum pump 1, gas-liquid separator 2 and control system 5, installing pressure transmitter 3 on gas-liquid separator 2, vacuum pump 1 connects converter 4, pressure transmitter 3 and converter 4 and is all connected with control system 5。
In use, by pressure transmitter 3, the vacuum that disclosure satisfy that dental comprehensive therapeutic chair is set, the vacuum degree measured by pressure transmitter 3 compares with setting vacuum degree, and the rotating speed of vacuum pump 1 is changed by converter 4, reduce or the purpose of Raise vacuum degree, to meet the needs of dental comprehensive therapeutic chair。Using the low ebb phase, vacuum pump 1 rotating speed is slow, and aspiration is little, and capacity is little, it is not necessary to mechanical valve is opened, and noise is low, and power consumption is low；Using peak period, vacuum pump 1 rotating speed is fast, it is possible to meet user's request。
Except above-mentioned points, for avoiding the dentistry motorized pumping systems that pressure transmitter 3 damage causes out of service, dentistry motorized pumping systems is set up the forced service switch 6 that a control converter 4 is opened, forces vacuum pump 1 to work。By closing forced service button, vacuum pump 1 can be made in the constant operation of setting speed, meet user's request。
