When the four column hydraulic press is pressed, the noise is loud, and the oil pipe is often cracke

Have you ever noticed how much pressure it is, and whether it is much more than usual?

The tubing will not be cracked, it must be suffocated by pressure, but the burst pressure should be at least 3-4 times the rated working pressure, under normal circumstances, as long as the selection is correct, it is impossible to achieve such a large pressure. Unless the tubing is not selected correctly, or there is a problem with the system's relief valve, the maximum pressure cannot be limited.

It is recommended to check the pressure first to see if the rated working pressure of the tube is exceeded. If so, check whether the relief valve is normal and can function as a safety valve.

The oil return part of the oil circuit is blocked, which will cause the oil pipe to burst.

Seamless tubes? High-pressure hose? Where are most of the cracks located?

In the case of seamless pipes, the clamp between the filling valve and the cartridge valve is not fixed, and the vibration will increase if the hydraulic pipe is too long.

In the case of high-pressure hoses, if they are not too thin or do not match the working pressure, they generally require a four-layer steel wire pipe for high pressure.

Look at the pressure gauge, whether the actual working pressure exceeds the pressure you need, and if the pressure is too large, you need to adjust the relief valve or oil pump.

First, the cause of the failure:

1. The pipe layout is unreasonable, and the interference of each component produces resonance.

2. The hydraulic pump is damaged and the flow is uneven.

3. Gas is mixed into the pipeline.

Second, the solution:

1. The hydraulic oil pump sucked in air bubbles

In order to remove the air, the whole hydraulic system can be run at no load, and the air in it can be completely removed before injecting hydraulic oil into the hydraulic station.

2. Poor operation of the damage of the hydraulic oil pump

The parts in the hydraulic pump of the hydraulic system are worn or damaged. If the inner surface of the stator ring of the hydraulic oil pump of the hydraulic station is seriously worn, then the stator ring should be replaced directly; If the gear accuracy of the hydraulic oil pump is low and the swing is large, then change or replace it.

3. The interference of each element produces resonance

The problem can be solved by adjusting the distance between the high-pressure pipe, such as the pipeline, and other parts, and fixing it so that it does not interfere with the collision.

Generally, it is the vibration caused by uneven flow. It can be caused by damage to the pump, or gas mixing into the system. See if the suction pipe of the fuel tank has a place to empty it. Then see if the pump is badly worn.

According to the principle of Rentong mechanical equipment, the noise of general hydraulic press is mainly as follows: 1. There is oil accumulation in the oil circuit of the hydraulic engine, and the oil circuit is not passable, which causes the oil circuit to block the oil pump and make a sound; Second, the oil pump has loss, not rotating, etc., will lead to the noise of the hydraulic press, third, the machine is unstable for a long time, and some parts shake to produce noise during work.

Excessive noise and vibration when cutting? The relief valve needs to be adjusted.

Also, check to see if the elastic block of the coupling is worn out and needs to be replaced.

The recommended answers are more general, and the specific problems and solutions are introduced below.

1: The hydraulic oil pump is worn or emptied.

2: The viscosity of the oil is too large, resulting in cavitation and cavitation, which makes the operation of the oil pump difficult 3: The oil contains mechanical impurities, which accelerates the wear of the hydraulic components and causes the failure of the hydraulic system 4: The oil inlet filter is seriously polluted and blocked.

Noise can be reduced according to the following methods:

1: Detect the wear of the hydraulic pump.

2: Appropriately reduce the viscosity, choose the hydraulic oil whose viscosity is affected by the temperature difference is small 3: Replace the oil.

4: Clean the inlet filter.

There are only two ways to deal with noise: one is to eliminate and find ways to reduce the factors that cause noise, such as reducing impact and strengthening shock absorption. The second is blocking, which is to establish a soundproof cover to block the noise in a small space.

The previous method requires relatively high technical requirements. The latter method can greatly reduce the noise level as long as you buy some slag wool and hang it inside the soundproof box with an iron grid net.

Wear tampons.

I wish you all the best in your work and to the next level!

The noise of the hydraulic press should be the noise of the hydraulic system, right? To be specific, it shouldn't be unbearable.

First of all, check the oil inlet filter of the oil pump, which should normally be the filter screen. Then there is the hydraulic fluid. Give it a try. The new hydraulic oil pump inlet does not have a filter.

One is to first determine where the noise source is, and then open the corresponding valve block to carefully check whether there is any stuckness.

There are many reasons for the noise of the hydraulic press, depending on the service life of the equipment, whether the screws are loose, and whether there is air inlet at the oil suction place, whether the oil pump is worn, whether the hydraulic fittings are operating normally、、、, etc.

What happens when the hydraulic oil pump moves together and the noise is too loud.

Generally, the oil pump is insufficient, such as the oil inlet pipe leakage, the oil level in the oil tank is low, and then the resonance of the oil pipe is generated, and the noise is emitted.

Wrong. It's okay to fix it. Check if the lower travel switch is broken.

Check to see if the relief valve is stuck.

Check the oil leakage of each valve body?

Hello! The four-column hydraulic press is generally cartridge valve, and the failure of the 1 circuit is also caused by no pressure.

The domestic piston pump is not worth much, so I bought it earlier.

It's just that I don't have the strength when I press hard.

Then look at the cylinder to see if it is leaking.
