Problems solved by technology

However, this method is not only complex in structure, but also with the increase of operating pressure and the decrease of operating temperature in the current refrigeration system, the pressure strength of the sheet metal parts is insufficient, the sealing is poor, and the thermal deformation is obvious, and it has gradually become the suction cavity. structural shortcomings

Embodiment Construction

[0014] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] like figure 1 As shown, the suction end cover of the semi-hermetic compressor with junction box of the present invention includes a main body 3 of the suction end cover, a junction box body 2 and the like. The main body 3 of the suction end cover is one of the main parts of the motor cavity structure. It is integrally cast with the junction box body 2 on the end surface and the opening of the safety relief valve 4. A series of wiring connections are arranged on the junction box body 2. The column is used to connect the cavity with the external environment.

[0016] In the actual operation process, the main body 3 of the suction end cover is connected to the compressor system components through the flange, the high-voltage wire and the control circuit line are connected to the terminal 1 from the outside, and the other end is conne...

Abstract

The invention relates to a semi-closed compressor gas sucking end cover provided with a wiring box. The gas sucking end cover is provided with a gas sucking end cover main body. The wiring box is arranged on one side of the gas sucking end cover main body in a cast manner to form an integrated wiring box casting structure. A wiring column is arranged in a wiring box body. A gas sucking cavity andexternal environment are isolated through the integrated wiring box casting structure. The wiring column connects an external high-voltage power line and a control circuit line with a motor through amotor leading wire. The motor leading wire is connected into a motor cavity through the wiring column on the wiring box body, and the pressure bearing ability and the sealing effect of the motor cavity can be improved. Compared with the traditional technology, the gas sucking end cover and the wiring box are integrated, the shell structure is simplified, the pressure bearing force in a gas suckingcavity is improved, leakage is reduced, the ability to resist extreme low-temperature and high-temperature environment is enhanced, and the design basis is provided for stable and safe operation of arefrigerating system.

Description

technical field [0001] The invention relates to a semi-hermetic compressor, especially a suction end cover structure of a semi-hermetic compressor. Background technique [0002] Refrigeration systems are widely used in refrigeration, food processing, medicine and chemical industries to provide cooling for environments below -15°C. In the refrigeration system, the compressor is its core component, and is often the most critical factor that determines the energy efficiency and stability of the refrigeration system. Due to the particularity of the refrigerant and the safety of the refrigeration system, the compressor of the refrigeration system often adopts a semi-hermetic design, that is, the compressor is integrally connected with the motor, and the whole machine is packaged. In this method, the refrigerant often enters through the motor side, flows through the motor cavity, and then enters the compressor suction cavity. [0003] In the semi-hermetic compressor system, sinc...
