Design and analysis of hydraulic system of 400 ton deep drawing hydraulic press

A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components, and hydraulic oil.

The function of the power element is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, which refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The structural forms of hydraulic pumps generally include gear pumps, vane pumps and piston pumps.

The role of actuators, such as hydraulic cylinders and hydraulic motors, is to convert the pressure energy of the liquid into mechanical energy to drive the load in a linear reciprocating or rotary motion.

Control elements (i.e., various hydraulic valves) control and regulate the pressure, flow and direction of fluids in hydraulic systems. According to the different control functions, hydraulic valves can be divided into pressure control valves, flow control valves and directional control valves. Pressure control valves are divided into benefit flow valves (safety valves), pressure reducing valves, sequential valves, pressure relays, etc.; Flow control valves include throttle valves, adjusting valves, diverter collector valves, etc.; Directional control valves include check valves, hydraulic check valves, shuttle valves, reversing valves, etc.

According to different control methods, hydraulic valves can be divided into on-off control valves, fixed-value control valves and proportional control valves.

Auxiliary components include oil tank, oil filter, oil pipe and pipe joint, sealing ring, pressure gauge, oil level oil temperature gauge, etc.

Hydraulic oil is the working medium for transferring energy in the hydraulic system, and there are several categories such as various mineral oils, emulsions and synthetic hydraulic oils.

What the hell are you trying to ask?

Looking for someone to design it all over?

Our company has a professional hydraulic technical team, which has worked in high-speed rail, aerospace, military industry, metallurgy and other fields for many years, and has solved major difficult problems many times with rich experience. Now officially launched the hydraulic system design and development business. If you have a hydraulic technical problem that you find difficult to solve, for example:

1.New hydraulic technology applications, such as pure water, hydraulic transmission systems, etc.

2.High-precision hydraulic servo system.

3.High-speed hydraulic servo system.

4.Energy-saving transformation of hydraulic system.

5.If there are any of the above problems, we will give you a satisfactory answer to the major technical equipment problems that have plagued the enterprises for a long time. We specialize in solving the most difficult problems.

In general, a power of the system is considered, so the speed should be considered for low voltage downstream, and the flow rate determines the speed, and the multi-pump confluence can be considered; The high pressure downlink mainly considers the high pressure and small flow, and it is recommended to use the unloading circuit of high and low pressure double pump combination for oil supply. The pressure holding depends on the length of time, and the upper limit can be considered for stroke valve.

A hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to achieve various processes. The hydraulic press is generally composed of three parts: the machine (main engine), the power system and the hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses.

This system is the simplest press system and should be well designed.

A high and low pressure oil pump, two solenoid reversing valves (electric-hydraulic reversing valves with large flow), two relief valves, and one pressure holding valve are sufficient.

Graduation projects and graduation ** cannot be sought.

There is a fee for all of them.

Bulk shipping is incomplete.

Or can be found.

That's definitely not going to work.

If you don't have time to do it yourself, or you can't do it.

It is recommended to find someone to do it for you.

If needed. Our team can do it too.

Original, customized according to requirements, package modification, package over, until passed for the void beam stop.

There is a q on the person

Domestic originals, 80,000, including full set of hydraulics and electrical control.

Imported components, 170,000, a complete set.

If you add the hollow frame, add another 110,000.

200,000 can make a 500-ton hydraulic press. Can be customized.

The reasons are as follows:1The handle of the relief valve is completely loosened, resulting in no pressure on the system; 2.

The boost solenoid valve is broken or does not work; 3.The check valve at the top of the press cylinder is not closed tightly (the check valve is used for the slider to quickly descend and replenish oil); 4.The main solenoid valve is broken or not reversed, and the median function allows the pump to be connected directly to the oil tank.

You join the "Hefei Haide Hydraulic Press" group, and I'll get you a copy.

The general hydraulic system consists of 8 parts, oil tank, filter, hydraulic pump, relief valve, throttle valve, reversing valve, hydraulic cylinder, and workbench.

Do you want hydraulic drawings or equipment products.

Because the drawing die is basically processed in one piece, only the pressure center and the stroke height need to be considered when adjusting the mold. After you can put it on the shelf, do two tries and check the size.
