Hydraulic press is an advanced hydraulic machine that uses liquid as a working medium to transfer power and realize various processes. Its working medium can be divided into oil and water, including oil hydraulic press and water hydraulic press. The selection of hydraulic press and the hydraulic press is based on the needs of machine tools. As a kind of hydraulic press, their main function is forging. According to the different process requirements, the requirements of the machine are also different. The oil hydraulic press is only a machine using hydraulic oil as the working medium. Many people in the market think that they are the same, but in fact they are different. Let’s understand the essential difference between the two.

应用范围

Hydraulic press:

Large working stroke, can exert the maximum working force on the workpiece in the whole stroke, can more effectively forge through the large section forging, no huge impact and noise, good working conditions, less environmental pollution. It is mainly used in various free forging processes of metal materials, such as upsetting, punching, reaming, staggering, rough turning, cutting, bending, stretching, etc.

单列液压出版社：

Widely used, suitable for different products processing operations, saving the cost of machine replacement. It can also be used for blanking and stretching of plastic products, stamping of products, stamping of nameplates and pressing of plastic powder products.

Four column hydraulic press:

铝制产品，压铸产品，镁合金产品，硬件产品，塑料产品切割，毛刺打孔，粉末产品按压，塑料产品按压安装和其他多功能；汽车行业，摩托车行业，汽车行业客户最喜欢的业务合作伙伴。

Difference and contrast

1. 油被广泛用作油中的培养基hydraulic press。水液压压力机将水与添加剂一起使用。
2. 石油压力的密封效果很好，因为油具有合适的粘度和良好的密封效果，而水几乎不是粘性，因此油作为液压培养基的性能比水更合适。
3. Oil itself has a lubricating effect, which can play a good lubricating effect on moving parts in hydraulic system.
4. 由于油的密封良好，因此还可以防止浸入油中时的成分生锈。在水中划分的成分会加速生锈，因为水是锈反应的反应物。
5. Although the internal parts will not rust when soaked in oil, the oil has its disadvantages.Because the hydraulic system leaks, the leaking oil will pollute the environment and the water will not.And the oil is flammable and can be dangerous.Therefore, maintenance of hydraulic system must be done well when using oil press to avoid oil leakage.
6. 石油比水贵，价格会更高。

液压压机通常用于高功率液压压机，例如10,000吨液压压机，这些压机需要过多的工作介质以考虑工作介质的价格。

Hydraulic presses包括油按,因为它们的类型different working media. The two include the relationship between the two. In fact, oil presses are widely used in current market applications and are often referred to as Four Column Hydraulic Press. Hydraulic oil has a smaller compression ratio than water and higher working precision, so it has strong stability. At present, most of the presses used in the market are oil presses, which is commonly referred to as hydraulic presses.

液压油按下通过液压系统设备的运行将机械能转化为功率能，其中液压油起着非常重要的作用。通常，根据不同的过程要求选择不同类型的机器。促销和使用hydraulic presshas made an outstanding contribution to the development of China’s machinery manufacturing industry.With the development of our economy, the machinery manufacturing industry is also developing rapidly. After the reform and opening up, we have actively studied and strengthened the economic development. The overall scale of the manufacturing industry has entered the ranks of major international producers. With the continuous exploration and innovation of China’s machinery industry, the overall competitiveness and development potential ofhydraulic presseshas basically approached the manufacturing level of developed countries.
