Working principle of dustproof test chamber
Dustproof test chamberIs an instrument designed to evaluate and measure the ability of equipment or equipment to resist penetration, abrasion or blockage by dust particles. Its main function is to evaluate the reliability and maintainability of various mechanical, optical, electrical, electronic, electromechanical and electrochemical devices in sand blowing, dust raising and falling dust environments. The main structure of the dustproof test box is composed of the instrument casing, fan, tuyere, filter element and test samples. It pushes a certain concentration of sand and dust to the device through the fan, checks the device's ability to prevent dust particles from penetrating, wearing and blocking, and can evaluate the maintenance of the original function of the entire device and whether it can continue to be stored and operated.
SC-015 Dustproof Test Chamber
What are the structural characteristics of dustproof test equipment for dustproof test chamber?
The dustproof test chamber is an important equipment to ensure the clean and normal operation of industrial equipment. Damage caused by friction parts, seals, power meters and other products. The box structure is processed by CNC machine tools, with non-reactive handles, imported stainless steel mirror panels for the inner tank, steel plate sprayed for the outer tank, lighting lights on the window, and test lead holes on the left side; the insulation material is polyester Urethane rigid foam, ultra-fine glass fiber cotton; double-layer high and low temperature aging-resistant silicone rubber door seal, insulated door frame, standard configuration multi-layer heating frost, lighting glass window, sample rack and test lead hole ; Its safety protection includes leakage, short circuit, over temperature, motor overheating, compressor overpressure, overload, overcurrent protection; heating system adopts nickel-chromium alloy electric heating heater; refrigeration system adopts fully enclosed air-cooled single-stage compression refrigeration method /Original/Full-enclosed air-cooled cascade compression refrigeration method and circulation system adopts temperature-resistant and low-noise air-conditioning motor multi-blade centrifugal wind wheel. It can be seen from the above overview that Dust-proof test chamber dust-proof test equipment achieves the ultimate in artificial environment simulation and precision structural design technology, which can effectively prevent industrial equipment from being damaged by sandstorms.
Dust-proof test chamber is the test equipment for simulating the sand and dust environment encountered by products to test their shell protection performance. It is mainly tested according to two grades of IP5X and IP6X. The surface of the shell is sprayed with plastic, and the color is coordinated, which is reliable and durable. Nowadays, with the development of transportation and logistics, more and more attention has been paid to dustproof test equipment, which can detect whether the outer packaging of products is safe and correct, so as to protect the safety of consumers.
Although the dust chamber is used to test the safety of products, it is also prone to failure. The following are Shanghai Lisun's suggestions on how to deal with the failure of the sand and dust test chamber:
First: Check whether the power supply and phase sequence are normal, and whether there is a neutral line.
Second: check whether the blower is working normally and whether the dust is dry.
Third: Check whether the vibration motor is normal.
Fourth: In order to operate the test chamber stably, the ambient temperature should be kept between 15-25 degrees, the relative humidity should be lower than 85%, and keep away from combustibles and high-temperature heat sources.
Fifth: Dedicated personnel to manage the operation, regular cleaning and maintenance, to ensure its performance and effect.
Dust-proof test chamber is a necessary equipment for testing product safety. When it breaks down, it should be serviced, maintained and repaired in the above-mentioned manner immediately. Proper use and careful maintenance of the dustproof test chamber can ensure its safety and long-term use.
