The utility model discloses aerify water to current compressor and pick up the processing cost increase problem that needs the special attention to observe and follow-up moisture drying aspect, the innovation provides a neotype detection device. The detection device is simple and convenient to mount and connect, is suitable for batch continuous operation, and is easy to recycle detection raw materials and observe detection results.
As an innovative core of the design. As shown in fig. 1, the detection device for detecting helium leakage of the compressor is characterized by comprising a helium detection instrument, a four-way connecting block 3 and a pressure gauge 4, a sealing tool 5, an air inlet pipeline and an exhaust pipeline which are connected in a related manner. The helium detecting instrument is used independently and not shown, and the four-way connecting block 3 is used as an adapter device of each part to realize the communication of helium in each part. When the four pipe joints of the four-way connecting block are seen, one end of the four-way connecting block is connected with the sealing tool 5 through the G1/4 interface and the high-pressure pipeline 6, and the four-way connecting block is used for quickly and hermetically assembling the compressor to be detected. The high-pressure pipeline 6 can be a Teflon hose, and other similar pipelines with the same performance can also be suitable. The other end of the four-way connecting block is directly connected with an SMC pressure gauge 4 through an RC1/4 interface, so that the real-time air pressure intensity of all pipelines in the four-way connecting block is monitored. And the other two ends of the air pipe are respectively connected with an external air source and a recovery source through a G1/4 interface and a high-pressure steel pipe and respectively used as an air inlet pipeline and an exhaust pipeline.
In further detail, an exhaust check valve 7 is arranged between the exhaust port and the four-way connecting block in the exhaust pipeline, and the exhaust port is externally connected with a recovery source; and an air inlet one-way valve 2 and a pressure reducing valve 1 are arranged between the air inlet and the four-way connecting block on the air inlet pipeline, and the air inlet is externally connected with a helium gas source. The total pressure of the helium gas source is 5 MPa.
As understood from the specific detection process of the detection device, when all parts are connected into a whole quickly, the sealing tool is particularly locked on the compressor through the locking screw rod, and the sealing tool and the compressor are connected in a sealing way and communicated with the inner cavity, so that the national standard design requirement is met. And then closing the exhaust check valve, opening the pressure reducing valve to adjust the helium pressure to 1.4MPa through the pressure reducing valve, opening the air inlet check valve to inflate the compressor, monitoring the test pressure by the pressure gauge to be 1.4MPa, and closing the check valve in the near term and maintaining the pressure when the inflation pressure reaches the required standard value.
The conventional leakage point of the compressor under the inflation and pressure maintaining conditions is relatively fixed, so a special helium detecting instrument is adopted to detect the specific part of the compressor, the helium detecting instrument can be of various models produced by various brands, only the precision meets the requirement, the selectable models are ES30A-He, ES10A10-He and the like, the sensitivity of the helium detecting instrument can reach 0.00001 level, data display is arranged on the instrument, an alarm prompt can be sent when the leakage condition is detected, and the misjudgment rate is close to 0. After the detection of any compressor is finished, only the exhaust check valve needs to be operated and opened, and the helium in the compressor is exhausted to the recovery source through the pipeline.
Therefore, the detection device can be understood that except the helium detection instrument, the other parts associated with the four-way connecting block are all once-used components which are repeatedly connected, when the compressors are detected in batches, only the sealing tool and the compressor are required to be operated to be in sealing butt joint and the corresponding valve is required to be opened and closed to control, and no extra connecting operation is required.
Therefore, the structural characteristics of the sealing tool need to be further understood so as to facilitate understanding of the sealing and quick-connecting performance of the sealing tool. As shown in fig. 2 and 3, the sealing tool 5 includes a base 51, a locking screw 52 penetrates through the base 51 to be abutted with an attachment hole (not shown) of the compressor, the base 51 is provided with sealing heads 53 and 54 on both sides of an abutment end of the locking screw 52 to communicate with an inner cavity of the compressor, the base 51 is provided with an air inlet connector 55 on a side surface of the locking screw 52 perpendicular to an axial direction and is connected with the four-way connector 3 through a pipeline, and the sealing head and the air inlet connector are communicated in the base. And more than one layer of sealing ring 56 is respectively arranged at the joint of the sealing head, the base 51 and the compressor, and more than two layers of O-shaped sealing rings 57 are arranged at the joint of the air inlet connector and the base. This achieves a completely leak-free outside the compressor on the detection device side.
