Piston Seals and Rod Seals are important seals used in mechanical equipment. Their main function is to prevent liquid and gas leaks and ensure the normal operation of mechanical equipment. Piston seals and rod seals are usually used in hydraulic and Pressure system, such as hydraulic cylinders and Pneumatic cylinder. The quality and performance of these seals directly affect the efficiency and lifespan of mechanical equipment.
The classification of piston seals and rod seals is mainly based on their material and design structure. According to the different materials, they can be divided into rubber seals, polyurethane seals, polytetrafluoroethylene seals, metal seals, etc. According to the different design structures, they can be divided into unidirectional seals, bidirectional seals, rotary seals, etc.
Rubber seals are a common type of seal, and their main material is rubber. Rubber seals have good sealing performance and wear resistance, and are suitable for medium and low pressure hydraulic systems and Pressure system. Polyurethane sealing element is a high-performance sealing element, and its main material is polyurethane. Polyurethane seals have high wear resistance, high temperature performance and high pressure performance, and are suitable for high-pressure hydraulic systems and Pressure system. PTFE sealing element is a corrosion-resistant sealing element, and its main material is PTFE. PTFE seals have excellent corrosion resistance and high temperature resistance, making them suitable for fields such as chemical and food processing. Metal seals are a type of high-temperature and high-pressure seal, mainly made of metal. Metal seals have high temperature and high pressure performance and corrosion resistance, and are suitable for high temperature and high pressure hydraulic systems and Pressure system.
Unidirectional seals and bidirectional seals are classified based on different sealing directions. A unidirectional seal can only prevent the leakage of liquid or gas from one direction, while a bidirectional seal can prevent the leakage of liquid or gas from both directions. Rotating seal is a type of seal that can rotate and is mainly used for sealing rotating shafts. Rotary seals are divided into unidirectional rotary seals and bidirectional rotary seals.

Air conditioning maintenance and repair professional company application process
Nowadays, almost every household has an air conditioner, and the demand continues to grow. This expansion has also led to numerous maintenance challenges. Unfortunately, unscrupulous companies are rampant, preying on unsuspecting consumers. Setting up a legitimate and professional air conditioning maintenance service is becoming increasingly necessary for many families. But how exactly does one go about establishing such an organization?
Many major air conditioning brands already have their own professional maintenance teams. If you wish to join these networks, your company would first need to register legally under the local business administration regulations. Afterward, you would apply for official maintenance qualifications from the respective air conditioning manufacturer. However, each company may have its own specific requirements, so it’s best to contact them directly for detailed guidance.
If you aim to offer services for all types of air conditioners, the process becomes slightly more complex. You’ll need to visit the local Trade and Industry Bureau to obtain a business license. The technical qualification level is determined by the Refrigeration Association. Given the prevalence of scammers posing as legitimate technicians, it’s crucial to report any suspicious activity to the police promptly.
Setting up an air conditioning maintenance company isn’t overly complicated, but there are a few key factors to consider. Primarily, having highly skilled technicians is essential. Some branded maintenance organizations provide comprehensive training programs for their staff. Additionally, maintaining transparency and honesty in your operations is critical to building trust with customers.
In summary, while the steps to start a maintenance business are straightforward, ensuring quality service and compliance with industry standards is paramount. As the demand for reliable air conditioning services grows, so too does the opportunity to establish a reputable organization.
