How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

Analysis of the Influence of Engine Speed ​​in Automobile Air Conditioner

 

The car air conditioner controller should be able to control the evaporating temperature, superheat, compressor speed, electronic expansion valve opening, evaporator fan speed and car interior temperature at the same time according to certain performance indicators. Unlike household air conditioners, the speed of the car air conditioner compressor changes with the speed of the car engine.

The cooling capacity of the car air conditioner is greatly affected by the engine speed. Therefore, the car air conditioning control system is a multivariable control system. The coupling relationship of various control parameters affects the quality of the car air conditioning control system. Therefore, it is very important to design a controller with a simple precompensator to decouple the coupling system of the car air conditioner.

Air conditioning system is mainly composed of compressor accumulator, expansion valve and other equipment. In the traditional semi-mechanical control system, the constant-capacity compressor controls the start and stop of the compressor through the electromagnetic clutch according to the evaporation temperature, and the thermal expansion valve reduces the pressure of the high-pressure liquid refrigerant to the evaporation pressure, so that it can be vaporized and absorbed in the evaporator. Heat, and it can also control the flow in the evaporator.

Traditional fixed-capacity compressors and expansion valves can no longer meet the requirements of high-efficiency and energy-saving automatic control. Therefore, it is necessary to study the control system of car air-conditioning with a new actuator. It adopts a multi-variable control strategy, and uses a variable speed compressor and an electronic expansion valve to comprehensively control the evaporation pressure and superheat.

In the experiment, a variable-speed compressor was simulated by a constant-capacity compressor driven by an AC motor, and an electronic expansion valve driven by a stepping motor was used for the experiment.
