Abstract
The utility model discloses a medical vacuum negative pressure machine equipment control device and relates to the aspect on control on the start and stop of a vacuum pump of a vacuum negative pressure machine. The technical defects that the stable running of a machine is affected and the noise is high because higher vibration is caused by overload of the vacuum pump when the vacuum pump is started or stopped are solved. The medical vacuum negative pressure machine equipment control device comprises a vacuum pump, wherein the vacuum pump is connected with an air storing tank through an air conducting pipe; a first electromagnetic valve is arranged on the air conducting pipe between the vacuum pump and the air storing tank; and the first electromagnetic valve and the vacuum pump are connected with a control unit. The device is characterized by also comprising a start/stop vacuum tank and a second electromagnetic valve, wherein one end of the second electromagnetic valve is connected with the air conducting pipe between the vacuum pump and the air storing tank, and the other end of the second electromagnetic valve is connected with the start/stop vacuum tank; and the control unit is also connected with and controls the second electromagnetic valve. During start or stop of the vacuum pump, the vacuum degree at an air pumping end is kept, the resistance of the air pumping end is reduced, the load of the vacuum pump is reduced, the vacuum pump is prevented from overloading, the service life of the vacuum pump is prolonged, higher vibration generated in the continuous start and stop process of the vacuum negative pressure machine is greatly reduced, the machine can stably run, and meanwhile the noise caused by vibration is reduced.
Description
Technical field
The utility model relates to medical negative pressure of vacuum machine technology field, is specifically related to the vacuum pump start and stop control aspect of medical negative pressure of vacuum machine.
Background technique
Medical negative pressure of vacuum machine is the sourceof negative pressure of medical central suction system, be the unit at central suction station, by the suction of vacuum pump unit, make the attraction system pipeline reach required negative pressure value, end in operating room, rescue room, therapeutic room and each ward produces suction, provides medical treatment to use.
Medical negative pressure of vacuum machine has two Nash hytors usually, and under " automatically " working state, one is main, and one is auxilliary.Two pump alternations, standby each other, double pump was worked simultaneously when single pump pumping speed was not enough; Under " manually " working state, a job, one is standby, also can two works simultaneously, with the continual proper functioning of assurance system.
The load of Nash hytor reduces along with the increase of degree of vacuum.When resistance of air was big in container, vacuum pump often was operated in overload, and along with the increase of degree of vacuum, electric current descends, the motor proper functioning.
Summary of the invention
In sum, the purpose of this utility model is to solve vacuum pump when starting or stoping, because of vacuum pump overload produce than big bang, influence the machine smooth running, technical deficiencies such as noise is big, and a kind of medical negative pressure of vacuum machine equipment control gear that proposes.
For solving the technical problem that the utility model proposes, the technological scheme that adopts is: a kind of medical negative pressure of vacuum machine equipment control gear, include vacuum pump, vacuum pump is connected with gas holder by air pipe, air pipe between vacuum pump and gas holder is provided with first solenoid valve, and described first solenoid valve and vacuum pump are connected with control unit; It is characterized in that: also include start and stop vacuum tank and second solenoid valve; Described second a solenoid valve wherein end connects air pipe between first solenoid valve and the vacuum pump, and the other end connects the start and stop vacuum tank; Described control unit also connects control second solenoid valve.
Described start and stop vacuum tank capacity is less than gas holder.
The controlling method of described auxiliary system, it is characterized in that: after control unit is received the electrical signal that general control system requirement vacuum pump starts working, control unit sends control signal, second solenoid valve is opened, first closed electromagnetic valve, just start working through scheduled time T1 final vacuum pump, control unit control is closed second solenoid valve, is opened first solenoid valve behind scheduled time T2 again, makes vacuum pump begin to extract the interior gas of gas holder, makes negative pressure; After control unit is received the out-of-work electrical signal of general control system requirement vacuum pump; open second solenoid valve, close first solenoid valve; the outage of control unit control vacuum pump is shut down behind scheduled time T3 again, closes second solenoid valve through scheduled time T4 more afterwards.
The beneficial effects of the utility model are: auxiliary system of the present utility model and method at vacuum pump when starting or stoping, keep the degree of vacuum of the end of bleeding, the resistance of the end that reduces to bleed makes the load of vacuum pump reduce, prevent the vacuum pump overload, the working life of improving vacuum pump.
Auxiliary by to the vacuum pump start and stop of this auxiliary system and method, can significantly reduce the negative pressure of vacuum machine constantly start and stopping process in produce than big bang, make the machine smooth running, reduce the noise because of the vibrations generation simultaneously.
Description of drawings
Fig. 1 is structural principle schematic representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and the preferred specific embodiment of the utility model the structure of inventing is further described.
Shown in Fig. 1, medical negative pressure of vacuum machine equipment control gear of the present utility model includes vacuum pump 1, gas holder 2, first solenoid valve 3, start and stop vacuum tank 4, second solenoid valve 5 and the control unit;
For vacuum pump 1 when starting or stoping, keep the degree of vacuum of the end of bleeding, the resistance of the end that reduces to bleed makes the load of vacuum pump reduce, and prevents that the method concrete processed of vacuum pump overload from being:
After control unit is received the electrical signal that general control system requirement vacuum pump starts working, control unit sends control signal, second solenoid valve 5 is opened, first solenoid valve 3 cuts out, just start working through scheduled time T1 final vacuum pump 1, control unit control is closed second solenoid valve 5, is opened first solenoid valve 3 behind scheduled time T2 again, make vacuum pump 1 begin to extract gas in the gas holder 2, make negative pressure;
After control unit is received the out-of-work electrical signal of general control system requirement vacuum pump; open second solenoid valve 5, close first solenoid valve 3; 1 outage of control unit control vacuum pump is shut down behind scheduled time T3 again, closes second solenoid valve 5 through scheduled time T4 more afterwards.
In specific implementation process, described scheduled time T1, T2, T3, T4 can set according to the required negative pressure value of gas holder 2 and the volume size of start and stop vacuum tank 4, and for example: scheduled time T1 is 3s, and scheduled time T2 is 5s, scheduled time T3 is 3s, and scheduled time T4 is 5s.
