First, we should understand the following points:

1. The greater the pressure of the cutting machine, the more hydraulic oil will be added;

2. Hydraulic oil brand must be brand hydraulic oil. Do not buy chemical oil cheaply;

3. Cut the size of the oil tank. If it cannot be determined, it can normally exceed 2 cm of the oil filter.

Remarks: at present, Great Wall is the main hydraulic oil for cutting machines in the domestic market. Generally, the hydraulic oil is added 46# great wall hydraulic oil, and the price is about 15 yuan per kilogram (about 2400-2500 yuan per barrel, a total of 170 kg). If the oil tank of 40 ton hydraulic cutting machine is used, about 80 kg of hydraulic oil should be added. Do not buy oil less than 10 yuan a kilogram. At present, 90% of the oil delivered by the cutting machine is chemical hydraulic oil. Be sure not to be greedy for cheap.

Finally, let's introduce the choice of hydraulic oil model: hydraulic oil is divided into 32#46#68#100#, 46# and 68# refers to viscosity. When the temperature is 40 ° C, the kinematic viscosity of the oil is in centistokes. The larger the label, the higher the consistency on the oil. Only cutting machine hydraulic oil with different viscosity can be used according to equipment requirements and external environmental factors. The natural 68# viscosity is higher than 46# viscosity. The use of hydraulic oil depends on the external environment. It is not suitable to use 46# cutting machine hydraulic oil in high temperature areas. Because its viscosity is not 68# high, and the oil viscosity will decrease (become thinner) with the increase of hydraulic system temperature in use, there will be no pressure in the cutting machine system.

After years of exchanges and in-depth exploration of the shoe machine industry, Qixin has tens of thousands of kinds of shoe machine accessories, and launched "Shulang brand" infrared machine lamp in 2010 "Walther brand" peeler has been unanimously recognized by our customers. In addition to its own brand, the company also distributes high-quality products of many brands at home, abroad and Yiwan. The products are not only sold in domestic provinces, but also exported to Southeast Asia, Europe and America.

Qixin shoe machine and accessories always adhere to quality for survival, reputation for development, innovation and sustainable development. We sincerely hope that friends in the shoe industry and the majority of people in the shoe industry who have always supported us will give more valuable opinions, win and benefit each other, and promote the higher, more professional and higher quality development of shoe machine technology.
