医药冷库制冷循环系统打造

作者:admin 来源:本站 发布时间:2018-3-29 17:07:19

医药冷库包含压缩机、蒸发器、冷凝器、节流设备四大部件。制冷剂循环进程如下图所示。医药冷库制冷循环在原理上与其他循环一样。吸气口坐落紧缩机电机端部。关于双机头机组,来自蒸发器的制冷剂进入紧缩机吸气口。
The medical cold storage consists of four parts: compressor, evaporator, condenser and throttle equipment. The process of refrigerant circulation is shown in the following diagram. The refrigeration cycle of the medical cold storage is the same as that of other cycles in principle. The suction port is located at the end of the motor of the tightening machine. With regard to the double head unit, the refrigerant from the evaporator enters the suction port of the tightening machine.
两个制冷剂体系各自独立,然后制冷剂气体均匀流过电机壳体,带走电机热量,进入螺杆慈和空间。螺杆彼此慈和使制冷剂气体紧缩,一起螺杆转子顶部喷油。与紧缩进程的制冷剂混合,清洗螺杆齿和内腔内壁。

The two refrigerant system independently, then the refrigerant gas uniform flow through the motor shell, motor and screw away heat into space. The screw and the refrigerant gas tight to each other, with the top injection screw rotor. Mixed with the refrigerant of the austerity process, cleaning the screw tooth and the inner wall of the inner cavity.

医药冷库油在离心力的作用下会集在通道壁上。终究,冷剂和剩下的油流经离心通道时。从这两部分别离进入的油会集在一次油分底部,然后流回紧缩机油槽。进入二次油别离器。二次油别离器相同包含一个离心流道, 这么含少数油冷剂气体流经止回阀和排气阻隔阀。后面有一个吸附别离段。油气混合物流经这两部分时,悬浮 态的微小油滴将别离出来。
Effect of cold medicine oil under the centrifugal force assembled in the channel wall. After all, the rest of the refrigerant and oil flowing through the centrifugal channel. From the two part respectively into the oil gathering in an oil bottom, then flows back to the compressor oil tank. Enter the two oil separation device. Two times the same oil separator contains a centrifugal flow, so with a few oil refrigerant gas flows through the check valve and exhaust valve block. There is an adsorbent segment in the back. When the oil and gas mixture flows through these two parts, the tiny droplets of the suspended state will be separated.
更首要的密封阴阳转子、内腔外表之间触摸空隙,医药冷库喷油不但能润滑螺杆驱动触摸面。空隙密封杰出,将削减紧缩机高低压侧之间冷剂的走漏,因此提高紧缩机功率,紧缩完成后冷剂气体和油得混合物从螺杆排气端排出,进入一次油别离器。
The more important seal Yin and Yang rotor, the inner cavity appearance between the touch of the gap, the medical cold storage oil injection can not only lubricate the screw drive touch surface. The sealing gap is good, the leak will cut the refrigerant between the compressor low pressure side, thus improving the compressor power, gas and oil tight after the completion of the mixture discharged from the exhaust end of the screw, into an oil separator.
一次油别离器坐落紧缩机排气一侧,由不锈钢丝网和离心通道构成。制冷剂气体和油的混合物流过不锈钢丝网,流速和方向的改变,这么部分油别离出来。
The first oil separation device is located on the exhaust side of the compressor, which is made up of stainless steel wire mesh and centrifugal passage. The mixture of the refrigerant gas and the oil flows through the stainless steel wire mesh, the flow velocity and the direction of the change, so that the part of the oil is separated.
医药冷库微量含油的制冷剂气体进入冷凝器。冷凝器内的分气板使气流均匀掠过冷凝管制。来自冷却塔的冷却水灾冷却管制内活动并带走冷凝热。使制冷剂气体不时过冷。
The refrigerant gas containing a trace of oil enters the condenser in the medical cold storage. The air separation plate in the condenser makes the air flow evenly over the condensing control. The cooling water cooling control from the cooling tower operates and takes away the heat of condensation. The refrigerant gas is too cold from time to time.
