Abstract
The utility model discloses a centrifugal machine which comprises a machine body (4). The machine body (4) is provided with a cabin door (10). The centrifugal machine is characterized in that at least two sensors, namely the sensor A (2) and the sensor B (3), are arranged on the contact face of the machine body (4) and the cabin door (10), when the cabin door (10) is closed, the sensor A (2) and the sensor B (3) simultaneously sense the cabin door (10), so that a switch of the sensor A and a switch of the sensor B are switched on, a circuit is switched on, and the centrifugal machine works normally. Compared with the prior art, the centrifugal machine has the advantages of being safe, high in reliability and the like.
Description
Technical field
The utility model relates to a kind of safe and reliable centrifuge.
Background technology
Current most chemical enterprise all can be used centrifuge, when maintenance centrifuge, for preventing error starting equipment in maintenance process, the power supply of maintenance of equipment need to be disconnected, but sometimes maintenance personal is when taking out centrifuge cone net, and centrifuge can be opened automatically, and accident causes casualties, the main cause of centrifuge self-starting is that after breaker artificially separates, the inner brace of breaker is due to the excessive high-temperature digestion of electric current, and when breaker disconnects on surface, contact does not disconnect.Therefore, a kind of safe and reliable centrifuge is suggested.
Summary of the invention
Safe and reliable centrifuge when the purpose of this utility model is to provide a kind of maintenance.
The utility model comprises body (4) and starter power supply, body (4) is located on base (1), body (4) is provided with hatch door (10), it is characterized in that: body (4) is provided with at least two inductors with the contact-making surface of hatch door (10), be inductor A(2) and inductor B(3), inductor A(2) inductive switch K2 and inductor B(3) inductive switch K3 connect and be arranged in the voltage circuit of centrifuge starter power supply.
In actual use, when hatch door (10) is closed, hatch door (10) contacts with body (4), inductor A(2) inductive switch K2 and inductor B(3) inductive switch K3 simultaneously closed, make the voltage circuit of centrifuge starter power supply closed, centrifuge is normally worked; When hatch door (10) is opened, hatch door (10) is separated with at least one inductor, and Centrifugal Machine Control circuit disconnects, and centrifuge is not worked.
Above-mentioned inductor is provided with four, be inductor A(2), inductor B(3), inductor C(6) and inductor D(7), and inductor A(2), inductor B(3), inductor C(6) and inductor D(7) inductive switch K2, K3, K6 and K7 connect and be arranged in the voltage circuit of centrifuge starter power supply.
Above-mentioned inductor is metal sensor, and is metal with the contact-making surface of body (4) inside hatch door (10), when hatch door (10) contacts with metal sensor, and closed circuit, centrifuge is normally worked.
Compared with prior art, the utlity model has security reliability high.

The specific embodiment
Embodiment 1: with reference to Fig. 1～2, structural representation for the utility model embodiment 1, comprise body (4) and starter power supply, body (4) is located on base (1), body (4) is provided with hatch door (10), it is characterized in that: body (4) is provided with at least two inductors with the contact-making surface of hatch door (10), be inductor A(2) and inductor B(3), inductor A(2) inductive switch K2 and inductor B(3) inductive switch K3 connect and be arranged in the voltage circuit of centrifuge starter power supply.
In actual use, when hatch door (10) is closed, hatch door (10) contacts with body (4), inductor A(2) inductive switch K2 and inductor B(3) inductive switch K3 simultaneously closed, make the voltage circuit of centrifuge starter power supply closed, centrifuge is normally worked; When hatch door (10) is opened, hatch door (10) is separated with at least one inductor, and Centrifugal Machine Control circuit disconnects, and centrifuge is not worked.
Embodiment 2: compare with embodiment 1, the difference of the present embodiment is: inductor is provided with four, be inductor A(2), inductor B(3), inductor C(6) and inductor D(7), and inductor A(2), inductor B(3), inductor C(6) and inductor D(7) inductive switch K2, K3, K6 and K7 connect and be arranged in the voltage circuit of centrifuge starter power supply.
