A kind of elastic clamping joint of enclosed ammonia-resistant motor

Abstract

The invention discloses an elastic clamping connector of an enclosed ammonia-resistant motor. A unique elastic clamping connector is employed, a traditional nut structure is abandoned, on one hand, rapid installation and disassembly of the connector is achieved, the assembly efficiency is remarkably improved, and the convenience of connector replacement and maintenance is achieved; and on the other hand, by the elastic clamping connector, the problem that a traditional nut connector is untight to lock to cause unstable signal due to vibration of the motor is further solved. The elastic clamping connector also has functions of elastic adjustment, clamping and rotation loosing prevention, elastic connection between an internal connector and an external connector after clamping and assembly is further achieved by elastic adjustment, and stable connection between the internal connector and the external connector can be further improved; and by a telescopic adjustment piece, the functions of clamping and rotation loosing prevention are achieved, and rotation and loosing between the internal connector and the external connector can be further prevented.

Description

technical field [0001] The invention relates to the technical field of refrigeration motors, in particular to an elastic clip joint of a closed ammonia-resistant motor. Background technique [0002] With the deteriorating environment, the original CFC refrigerant has been gradually replaced by ammonia refrigerant and has become a new refrigerant material. Ammonia is currently the most widely used medium-pressure medium-temperature refrigerant. The solidification temperature of ammonia is -77.7°C, the standard evaporation temperature is -33.3°C, and the condensation pressure is generally 1.1-1.3MPa at room temperature. It is absolutely impossible to exceed 1.5MPa at 30°C. The unit standard volume refrigeration capacity of ammonia is about 520kcal / m 3 ; It will become the general trend to use ammonia as the internal refrigerant of the compressor to manufacture motors and then manufacture refrigeration equipment. However, the existing general-purpose standard motors, or othe...

AI Technical Summary

Problems solved by technology

However, the existing general-purpose standard motors, or other types of motors, mainly consider the temperature resistance level of the motor, and it is difficult to find insulating materials that can work stably in liquid ammonia, such as insulating paper, magnet wire, impregnated varnish, etc.

[0003] For the joints of closed ammonia-resistant motors, as in the company's previous patent applications, such as in the application numbers 201510185413.6 and 201510185295.9, nut joints are used, but nut joints are used. In specific installation, When disassembling, the joint needs to be rotated and installed, which will cause certain damage to the joint and affect the stability of the structure; on the other hand, due to the vibration of the motor during operation, the nut-type joint is easy to loosen under long-term operation. Cause poor contact, and then affect the stability of the ammonia-resistant motor
