Cooling type screw unit convenient to disassemble, repair and maintain

Abstract

The invention discloses a cooling type screw unit convenient to disassemble, repair and maintain, and relates to the field of screw water chilling units. The cooling type screw unit comprises a bottomplate, wherein a fixing frame and a sliding groove are formed at the top of the bottom plate, a sliding block is installed in the sliding groove, the top of the sliding block is connected with a supporting groove through a connecting rod, a damping spring is fixed to one side of the sliding block, a movable groove is formed in the inner side of the fixing frame, when the screw unit vibrates, pressure is applied to the connecting rod through vibrating power, the bottom end of the connecting rod pushes the sliding block to slide in the sliding groove, the sliding block extrudes the damping spring in the moving process, under the effect of the damping spring, buffering force can be buffered, and therefore, the damping purpose is achieved; and moreover, in the vibration process, a pulley slides up and down in the movable groove, so that the operation stability of the supporting groove and the unit is improved, noise can be reduced in the damping process, noise pollution is reduced, the service life of the screw unit is effectively prolonged through damping, and the cost of repair and maintenance expenses in the later use period is reduced.

Description

technical field [0001] The invention relates to the field of screw chillers, in particular to a cooling type screw chiller which is convenient for disassembly, repair and maintenance. Background technique [0002] The screw chiller gets its name because it uses a screw compressor. Its cooling power is larger than that of the scroll chiller, and it is mainly used in chemical plants, ink printing plants, automobile manufacturing plants or central air-conditioning systems or other large-scale industrial refrigeration. The screw chiller uses compressors for its key components The screw type is called the screw type chiller. The unit is made of gas refrigerant in the state of the evaporator; after being adiabatically compressed by the compressor, it becomes a state of high temperature and high pressure. The compressed gas refrigerant is cooled and condensed at equal pressure in the condenser, and then becomes a liquid refrigerant after being condensed, and then expands to a low ...
