Engineering plastic Pom Sprocket wheel
POM(Polyformaldehyde) is a engineering plastics of non-side-chain, high density, high crystalline and linear polymer, which is praised “Plastic Steel”, and has comprehensive excellent performances, such as: Wear-resistance, high hardness, anti-impregnant, good rigidity (Tensile modulus of elasticity), chemical stability, isolation resistance and dimensional stability. POM has widely applied in Automobile industries, electronic and electric products, commodity, pipeline & fittings, exact apparatus and so on, which can be instead of the bronze, Zinc, tin and other metals.
Except POM-H is often copolymerized with ethylene oxide together, in order to avoid the melting of POM material in the high temperature. POM-H has the better performances than POM-C in its high crystalline, mechanical strength and rigidity. And POM-C has the better performances than POM-H in its low melting point, temperature stability, fluxion characteristic and machining capability.
Father more, POM-H+PTFE, which is made from the Delrin POM Resin that maxed Teflon fiber symmetrically, has the low co-efficient of frication, good lubrication, wear-resistance, non-creepage resistance.

Can air compressors be used for cleaning and blowing dust?
Yes, air compressors can be effectively used for cleaning and blowing dust in various applications. Here’s how air compressors are utilized for these purposes:
1. Cleaning Machinery and Equipment:
Air compressors are commonly used for cleaning machinery and equipment in industries such as manufacturing, automotive, and construction. Compressed air is directed through a nozzle or blowgun attachment to blow away dust, debris, and other contaminants from surfaces, crevices, and hard-to-reach areas. The high-pressure air effectively dislodges and removes accumulated dust, helping to maintain equipment performance and cleanliness.
2. Dusting Surfaces:
Air compressors are also employed for dusting surfaces in various settings, including homes, offices, and workshops. The compressed air can be used to blow dust off furniture, shelves, electronic equipment, and other objects. It provides a quick and efficient method of dusting, especially for intricate or delicate items where traditional dusting methods may be challenging.
3. Cleaning HVAC Systems:
Air compressors are utilized for cleaning HVAC (Heating, Ventilation, and Air Conditioning) systems. The compressed air can be used to blow dust, dirt, and debris from air ducts, vents, and cooling coils. This helps improve the efficiency and air quality of HVAC systems, preventing the buildup of contaminants that can affect indoor air quality.
4. Blowing Dust in Workshops:
In workshops and garages, air compressors are often used to blow dust and debris from workbenches, power tools, and work areas. Compressed air is directed to blow away loose particles and maintain a clean and safe work environment. This is particularly useful in woodworking, metalworking, and other trades where dust and debris can accumulate during the manufacturing or fabrication processes.
5. Cleaning Electronics and Computer Equipment:
Air compressors are employed for cleaning electronics and computer equipment. The compressed air is used to blow dust and debris from keyboards, computer cases, circuit boards, and other electronic components. It helps in preventing overheating and maintaining the proper functioning of sensitive electronic devices.
6. Industrial Cleaning Applications:
Air compressors find extensive use in industrial cleaning applications. They are employed in industrial settings, such as factories and warehouses, for cleaning large surfaces, production lines, and equipment. Compressed air is directed through specialized cleaning attachments or air-operated cleaning systems to remove dust, dirt, and contaminants efficiently.
When using air compressors for cleaning and blowing dust, it is important to follow safety precautions and guidelines. The high-pressure air can cause injury if directed towards the body or sensitive equipment. It is advisable to wear appropriate personal protective equipment, such as safety glasses and gloves, and ensure that the air pressure is regulated to prevent excessive force.
Overall, air compressors provide a versatile and effective solution for cleaning and blowing dust in various applications, offering a convenient alternative to traditional cleaning methods.

如何排查常见的空气压缩机故障？
排查常见的空气压缩机故障有助于识别和解决可能影响压缩机性能和功能的问题。以下是一些排查常见空气压缩机故障的步骤：
1. 无电：
- 检查电源并确保压缩机已正确插入插头。
- 检查断路器或保险丝盒，确保其没有跳闸或熔断。
- 请确认压缩机的电源开关或控制面板已打开。
2. 低气压：
- 检查压缩机上的气压表。如果压力低于所需值，则压缩机可能无法建立足够的压力。
- 检查系统是否存在漏气。漏气会导致压力下降。仔细聆听是否有嘶嘶声，或者使用肥皂水溶液来确定漏气位置。
- 确保压缩机的进气过滤器清洁且未堵塞，因为这会限制气流并降低压力。
3. 噪音或振动过大：
- 检查压缩机的安装支架和底座，确保其牢固稳定。松动的支架会导致过大的噪音和振动。
- 检查是否有松动或损坏的部件，例如皮带、滑轮或电机支架。必要时拧紧或更换。
- 检查压缩机的冷却系统，例如风扇或散热片，是否清洁且无堵塞。过热会导致噪音和振动增大。
4. 漏气：
- 检查所有连接件、阀门、接头和软管是否有泄漏。拧紧或更换任何松动或损坏的部件。
- 在疑似漏气区域涂抹肥皂水溶液，观察是否有气泡冒出。气泡的出现表明存在漏气。
- 建议在螺纹连接处使用螺纹密封剂或特氟龙胶带，以确保密封良好。
5. 压缩空气中水分过多：
- 检查压缩机的排水阀，确保其工作正常。打开阀门排出积聚的水分。
- 检查并清洁压缩机的水分分离器或空气干燥器（如有配备）。
- 考虑安装额外的过滤或干燥设备，以去除压缩空气系统中的水分。
6. 电机过热：
- 确保压缩机的冷却系统清洁畅通。
- 检查发动机的进气口，清除可能阻塞气流的灰尘或碎屑。
- 确认压缩机未在过热环境下运行。
- 检查电机润滑油液位，确保其在制造商建议的范围内。
- 考虑使用热过载保护器来防止电机过热。
如果排除这些常见问题后问题仍然存在，则可能需要查阅制造商手册或寻求合格技术人员的帮助。定期维护，例如清洁、润滑和检查，也有助于预防常见问题，并确保空气压缩机的最佳性能。

空气压缩机中的气压是如何测量的？
空气压缩机中的气压通常使用两种常用单位之一来测量：磅/平方英寸 (PSI) 或巴 (bar)。以下简要说明空气压缩机中气压的测量方法：
1. 磅/平方英寸（PSI）： PSI（磅/平方英寸）是空气压缩机中最常用的压力测量单位，尤其是在北美地区。它表示一磅力作用于一平方英寸面积上所产生的力。空气压缩机上的压力表通常以PSI为单位显示压力读数，方便用户监控和调节压力。
2. 酒吧： 巴（bar）是空气压缩机中常用的另一种压力单位，尤其在欧洲和世界许多其他地区。它是公制压力单位，等于100,000帕斯卡（Pa）。空气压缩机可能配备以巴为单位显示读数的压力表，为这些地区的用户提供另一种测量方式。
为了测量空气压缩机内的气压，通常会在压缩机的出口或储气罐上安装压力表。压力表用于测量压缩空气产生的压力，并以指定的单位（例如 PSI 或 bar）显示读数。
需要注意的是，压力表上显示的气压值代表空气压缩机系统中特定点的压力，通常是出口或储气罐处的压力。实际使用时的压力可能会因多种因素而有所不同，例如气路中的压力下降或接头和工具造成的阻力。
使用空气压缩机时，必须将压力设置为特定应用所需的合适水平。不同的工具和设备对压力的要求各不相同，超过推荐压力可能会导致损坏或操作不安全。大多数空气压缩机都允许用户使用压力调节器或类似的控制机构来调节压力输出。
定期监测空气压缩机的气压对于确保其最佳性能、效率和安全运行至关重要。通过了解测量单位并正确使用压力表，用户可以将空气压缩机系统的气压维持在所需的水平。
