We usually inject a certain amount of lubricating oil into the machine before using the reducer. The injected lubricating oil has very strict requirements on viscosity. Therefore, viscosity is an important physical and chemical index of gear oil. The viscosity of the oil is selected correctly. , It will reduce the internal friction of the lubricating oil, thereby reducing the wear on the gear surface of the reducer and the transmission noise, vibration, etc. Then, what is the appropriate viscosity of the lubricating oil? The reducer manufacturer introduced the following to us.
1. The viscosity of the lubricating oil of the reducer is mainly realized by the base oil and the viscosity index improver. Among them, the viscosity of the base oil is related to the molecular structure and molecular weight. The larger the average molecular weight, the greater the viscosity of the oil.
2. A good viscous agent should have high viscosity increasing ability, good shear stability, good low temperature performance and thermal oxidation stability.
3. For lubricating oils of the same viscosity grade, if you choose non-refined base oils and not very good viscosity indexing agents, although a certain viscosity standard can be reached after blending, but the viscosity-temperature, shear stability and other properties Poor, the same can not reach the expected life cycle.
In actual production, we can choose the lubricating oil viscosity of the reducer according to the above method. For low-speed and heavy-duty reducers, we should choose high-quality high-grade lubricating oil, and try to avoid using non-refined base oils or poor viscous agents Because its base oil and viscous agent are better, the greater the viscosity of the gear oil, the stronger the protection against various damages to the tooth surface, and the smaller the mechanical wear.
Our products are mainly exported to Japan, the United States, Germany, Southeast Asia and other countries and regions. Our customers include many OEM customers specializing in construction machinery. We have partnered with several of the Fortune 500 companies to become one of their major foundry suppliers in China.
How to provide goods?
Usually we will ship the goods to the sea. The factory is only 460 kilometers away from the port. It is very convenient and convenient to transport the goods to any other country. Of course, if your cargo is very urgent, Ningbo Airport and Shanghai Airport are also nearby.
What is the payment term?
When we offer you a quote, we will confirm the transaction method with you, FOB, CIF, CNF, etc. For large-scale production, you need to pay a 30% deposit before production and a 70% balance on the copy of the document. The most common way is T/T. Letter of Credit is also acceptable.
How to ensure the quality of your products?
First, we will check after each process. For finished products, according to customer requirements and international standards.
How many employees does your company have? What is the relationship between technicians?
We now have more than 180 employees, including 36 engineers and 28 QCs.
What is the ability of your company?
We have a number of production lines with a monthly production capacity of 1,600 units and an annual production capacity of 20,000 units.
