Main types of hydraulic press machine:
The working principle of the 600 ton hydraulic press machine is that the oil pump delivers hydraulic oil to the integrated cartridge valve quickly. The hydraulic oil is distributed to the cylinder cavity through each one-way valve and relief valve, and the cylinder moves under the action of high pressure oil. Whether it is oil hydraulic press machine or water hydraulic press machine, collectively referred to as hydraulic press machine. What is the difference between 600 tons oil hydraulic press machine and 600 tons water hydraulic press machine? Hydraulic equipment is liquid as the medium, the composition can be divided into oil and water, respectively known as oil hydraulic press and water hydraulic press equipment. Oil hydraulic equipment is widely used, because the oil hydraulic press uses oil as the working component, and water hydraulic press is added with special additives of water. Hydraulic oil components are much better than water in terms of performance. Because the oil has a more suitable viscosity, sealing effect is good. And the hydraulic oil has lubrication effect, can have good lubrication of the hydraulic system internal moving parts. The machine parts will not rust if they are soaked in oil. But hydraulic oil also has disadvantages. When the machine is used too many times or its life is too long, the wear and aging of parts will cause hydraulic oil leakage in the hydraulic system. Leakage of hydraulic oil will pollute the environment, and hydraulic oil is flammable. Hydraulic machinery widely used in the market are basically oil hydraulic press. Water hydraulic press machine is usually only used in large power hydraulic press, such as ten thousand tons of water hydraulic press machine, these systems need to work in the medium is very much, so the use cost of these working media to customers is very high. With the development of China’s economy, the machinery manufacturing industry is also developing by leaps and bounds. China’s manufacturing level has also been a qualitative leap, so the quality and design of hydraulic press machine can fully meet the high standards of all walks of life in the world.
What are the hydraulic circuits in the 600 ton hydraulic press machine?
- Pressure control loop When choosing various pressure control circuits, we should carefully consider the problems needed to be considered in the selection of this circuit and its characteristics and application occasions. For example, the power loss, temperature rise, instantaneous change of flow rate and pressure caused by unloading should be considered when selecting the unloading circuit.
- Speed control loop. According to the pressure, flow and power on the working condition diagram of the hydraulic actuator and the requirements of the system on temperature rise, working stability and so on, choose the speed control loop.
- Multi-cylinder motion loop. Compared with single cylinder motion loop, multi-cylinder motion loop needs to consider the relationship between the multi-cylinder, such as synchronous action, whether interference, action sequence, no action of hydraulic cylinder unloading problem. Each cylinder speed, change, pressure limit and other problems, according to the single cylinder circuit selection, and in the synthesis of hydraulic system to do some necessary adjustment.
- Fast motion loop and speed change-over loop,The fast motion loop is closely related to the speed regulation loop. The fast motion loop must be considered when selecting the form of oil source, system efficiency and temperature rise in the speed regulation loop,Once the speed regulating loop is determined, the fast motion loop is basically determined. The structure of the speed change loop is determined by the speed regulating loop and the fast motion loop. When selecting the speed commutation loop, it is necessary to determine whether to select the mechanical control commutation mode or the electrical control commutation mode according to the specific requirements of the system.
