Abstract
The utility model discloses a vacuum pump mounting structure of a vacuum cabin. The vacuum pump mounting structure comprises a vacuum pump and a vacuum cabin, wherein an extraction opening is formed in the vacuum cabin, an air suction port and an exhaust port are formed in the vacuum pump, the vacuum pump is sealed in a housing, an air inlet and an air outlet are formed in the housing, the air suction port of the vacuum pump is communicated with the air inlet of the housing through an air inlet pipe, and the exhaust port is communicated with the air outlet of the housing through an exhaust pipe; and a pressure sensor is further arranged in the housing and is connected with a control device, and the control device is connected with the vacuum pump and can control the vacuum pump to work. Due to the adoption of the structure, the mounting of the vacuum pump is more convenient, and the sealing property of the vacuum cabin can be effectively guaranteed.
Description
Technical field
The utility model relates to vacuum pump, particularly a kind of attachment structure of vacuum pump of vacuumizing for the vacuum storehouse.
Background technique
Vacuum pump has all obtained using very widely in a lot of fields as a kind of device that vacuumizes.Vacuum pump mainly is by the exhaust of bleeding of the modes such as the volume-variation of container or extruding.Thereby reach the purpose that vacuumizes.Existing vaccum pump unit generally adopts the AC and DC motor as motive force, and the pump housing mainly comprises the mechanisms such as piston, screw rod, impeller or diaphragm, and the pump housing is provided with independently inlet hole and exhaust port.
Be mainly used in vacuumizing (such as Vacuum refrigerator) to the vacuum storehouse at many occasion vacuum pumps, in this case, degree of vacuum in the vacuum storehouse generally has certain requirement, when the practical vacuum degree in the hole capital after selling all securities of taking seriously is higher than the degree of vacuum of regulation, just need to vacuumize to the vacuum storehouse by vacuum pump.Degree of vacuum generally detects by being arranged on vacuum storehouse pressure sensor in the vacuum storehouse, therefore often need pressure transducer is installed in the vacuum storehouse, because the vacuum storehouse is very strict to the requirement of sealing, therefore pressure transducer installs inconvenience very, even also be easy to after installing the sealing in vacuum storehouse is caused adverse influence.
The model utility content
For above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model provides a kind of need not pressure transducer is installed to attachment structure of vacuum pump in the vacuum storehouse.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
The attachment structure of vacuum pump in a kind of vacuum storehouse, comprise vacuum storehouse and vacuum pump, described vacuum storehouse is provided with a bleeding point, described vacuum pump is provided with intakeport and relief opening, described vacuum pump is sealed in the housing, described housing is provided with suction port and air outlet, the bleeding point in described vacuum storehouse is communicated with the suction port of described housing by a suction tude, the relief opening of described vacuum pump is communicated with the air outlet of described housing by an outlet pipe, also be provided with a pressure transducer in the described housing, described pressure transducer is connected with a control gear, and described control gear is connected with described vacuum pump, and described control gear can be controlled described vacuum pump work.
Preferably, described control gear is a relay, and described pressure transducer is connected with the control coil of described relay, and a pair of normally opened contact of described relay is connected with power line and described vacuum pump respectively.
Technique scheme has following beneficial effect: this attachment structure of vacuum pump is sealed in vacuum pump in one housing, the suction port of housing is communicated with the air outlet in vacuum storehouse, therefore the pressure in the housing is identical with the pressure in vacuum storehouse, pressure transducer is installed in the pressure that just can detect in the housing in the vacuum storehouse like this, and need not to be installed in the vacuum storehouse, therefore adopt this structure for vacuum pump to install more convenient, and can effectively guarantee the sealing in vacuum storehouse.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, the attachment structure of vacuum pump in this vacuum storehouse comprises vacuum storehouse 1 and vacuum pump 4, vacuum storehouse 1 is provided with a bleeding point, vacuum pump 4 is provided with intakeport and relief opening, vacuum pump 4 is sealed in the housing 9, housing 9 is provided with suction port 8 and air outlet, and the bleeding point in vacuum storehouse 1 is communicated with the suction port of housing 9 by a suction tude 2, and suction tude 2 is tightly connected with the bleeding point in vacuum storehouse 1, the suction port of housing 9.The relief opening of vacuum pump 4 is communicated with the air outlet of housing 9 by outlet pipe 3, and outlet pipe 3 is tightly connected with the relief opening of vacuum pump 4, the air outlet of housing 9.Also be provided with a pressure transducer 6 in the housing 9, pressure transducer 6 is connected with a control gear 7, and control gear 7 is connected with vacuum pump 4, and control gear 7 can be controlled vacuum pump 1 work.
As a kind of preferred version, control gear 7 can adopt a relay, and pressure transducer 6 is connected with the control coil of relay by wire 5, and a pair of normally opened contact of relay is connected with the power line of power line and vacuum pump 4 respectively.
This attachment structure of vacuum pump is sealed in vacuum pump 4 in the housing 9, the suction port of housing 9 is communicated with the air outlet in vacuum storehouse 1, therefore the pressure in the housing 9 is identical with the pressure in vacuum storehouse 1, pressure transducer 6 is installed in the pressure that just can detect in the housing 9 in the vacuum storehouse like this, and need not to be installed in the vacuum storehouse.Pressure in pressure transducer 6 detects housing 9 is greater than specified value (this specified value can be regulated as required), 6 of pressure transducers send and feed back signal to relay, make the normally opened contact of relay closed, thereby vacuum pump 4 actions are vacuumized to vacuum storehouse 1.
Adopt this attachment structure of vacuum pump to need not setting pressure sensor in the vacuum storehouse, vacuum pump 4, pressure transducer 9 are salable directly to be connected with vacuum storehouse 1 as an assembly housing 9 is interior, and need not to change the structure in the vacuum storehouse 1.Therefore adopt this structure for vacuum pump to install more convenient, and can effectively guarantee the sealing in vacuum storehouse.
The attachment structure of vacuum pump in above a kind of vacuum storehouse that the utility model embodiment is provided is described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; all will change in specific embodiments and applications; in sum; this description should not be construed as restriction of the present utility model, and all any changes of making according to the utility model design philosophy are all within protection domain of the present utility model.
