CN-122016013-A - Water flow switch detection counterweight device and water flow switch detection counterweight method

Abstract

The invention provides a water flow switch detection counterweight device and a water flow switch detection counterweight method, wherein the water flow switch detection counterweight device comprises a counterweight block; the hook is arranged at one end of the connecting piece far away from the balancing weight, and when in detection, the hook stretches into the pipeline and is lapped on the target piece of the water flow switch, and the connecting piece is inclined downwards under the dead weight and is abutted against the lower edge of the pipe orifice of the pipeline so as to hook the target piece to realize the simulated water flow signal. The device can simulate water flow signals without water and high-flow gas, and keeps triggering the target piece in the detection process so as to stably detect the on-off state of the water flow switch. Because no large air flow is needed to be introduced, the noise in the detection process of the water flow switch can be greatly reduced, thereby avoiding affecting the noise diagnosis and detection of other parts of the air conditioner by a tester in the test process, preventing the occurrence of faults of missing detection of other noise and ensuring the quality control and observation of the air conditioner production process. In addition, the device also reduces the production and detection cost of the air conditioner.

Background The water flow switch is a key component in an air conditioning pipeline system and is generally used for detecting the water flow in a pipeline of the refrigeration system so as to ensure the normal operation of the system. Water-through or ventilation detection is a method for detecting the state of water flow on-off by simulating water flow signals in pipelines commonly used in two air conditioning systems. However, for water flow detection, the whole machine has the adverse effect of longer water removal process time after detection is finished, the air conditioner detection cost is increased, and the production efficiency is reduced, and the ventilation detection is suitable for small-diameter pipelines, because the state of a water flow switch can be effectively detected only by introducing smaller air quantity into the pipelines, and the noise generated when the air with smaller air quantity flows in the detection process is relatively smaller due to smaller inner diameter of the small-diameter pipelines. However, for the large-diameter pipeline, in order to effectively detect the water flow on-off state, the ventilation volume may need to be increased, and because the inner diameter of the large-diameter pipeline is larger, the noise generated when the same amount of gas flows is larger than that of the small-diameter pipeline, the noise is greatly enhanced when the ventilation volume is increased, so that the noise diagnosis and detection of other parts of an air conditioner by a tester in the testing process are influenced, other noise faults are easy to leak and detect, and the adverse effects are caused on the air conditioner production process and quality control observation. In addition, increased ventilation can result in a simultaneous increase in machine power and energy consumption, thereby increasing air conditioner production and detection costs.
