How the hydraulic system is cleaned

You should be talking about the cleaning of the hydraulic system during maintenance.

Pipes generally do not need to be cleaned.

Pumps and valves can be removed and cleaned in diesel (the cleaning effect is better and safer than gasoline!!

When cleaning the fuel tank, drain the oil, remove the filter, and put it in the diesel fuel to clean.

Then the hydraulic station is cleaned, first the oil is cleaned, and then the impurities in the oil tank are glued clean with dough.

Once this is done, start reloading.

Okay, at this time, inject clean hydraulic oil, start to start the hydraulic system, circulate the hydraulic oil, and at this time you can beat the hydraulic pipe.

Stop at intervals (1 hour effect) Remove the filter Observe the impurities, and clean the filter if it is still dirty.

Generally no problem.

In addition, if the requirements are strict, a particle counter can also be used to count the number of impurities of different diameters in the oil.

Pickling, for pipelines·· Freshly installed hydraulic system, welded piping

1;Replace the filter element of the high-pressure or return oil filter, and the filtration accuracy is more than 40% higher than the original. Then the system runs for 10-16 hours.

2. Clean the inside of the fuel tank with diesel or gasoline through the fuel tank cleaning window.

3. Replace the new high-pressure or return oil filter element, the original one.

1.It is difficult to remove all the components and clean them with gasoline, and it is best not to do this if you are not very proficient.

2.Put the original oil out, add new hydraulic oil, work a few times, put the oil out, add new oil, work a few times, put it down, add new oil, work a few times. Generally, it is almost the same to add oil three times from the new one.

The cleaning process of our factory (continuous rolling seamless steel pipe), (beating cycle process):

1. The main pumping station is used as the power source, if your factory has the conditions to prepare it separately, this is the best, but the displacement must be enough.

2. To make a flushing plate, it is not easy to replace the waste valve body with a waste valve body, and it is never allowed to use a new valve to circulate.

3. After the pipeline welding and laying is completed, it should be purged with high-pressure air and knocked at the welding point.

4. Add flushing oil, according to the size of the system, select the pressure, our factory is now used for flushing, the temperature is 55 65. Keep tapping the weld point.

5. Replace the filter element in time and do an oil check when flushing.

6. After rinsing, put out the oil in the mailbox and clean the inner surface of the mailbox with flour.

7. Re-add the working oil with the oil purifier, connect the pipeline, first in a small range, slow motion, and expand in turn.

Attention to the problem, 1, can not be directly flushed with working oil, 2, can not be flushed with working valve.

3. If the oil grade is not up to standard, it is not allowed to access the valve platform.

Washing hydraulic oil is useful in the following ways:

1. Oil stains on clothes can be made with rosin perfume.

Banana water, gasoline, etc., then soak in 3 salt water for a few minutes, then rinse with clean water.

2. If the silk jewelry is stained with oil, acetone can be used.

The solution can be gently scrubbed.

3. Oil stains on dark clothes can be decontaminated by scrubbing with residual tea leaves.

4. Mix a little toothpaste with laundry detergent.

Mix and scrub the oil stains on the clothes, and the oil stains can be removed.

5. Take a little flour, mix it into a paste, apply it to the front and back of the clothes, dry it in the sun, and remove the husk to remove the oil stains.

<> hydraulic system provides power for the construction crane operating device, and the correct maintenance of the hydraulic system is very important to improve the operational reliability of the crane.

Generally speaking, the hydraulic system is generally washed before it is officially put into operation, and the purpose of flushing is to remove the pollutants, metal shavings, fiber compounds, iron cores, etc. remaining in the system, and in the first two hours of work, even if the system is not completely damaged, it will cause a series of failures. Therefore, the following steps should be followed to clean the oil circuit of the system:

1) Clean the tank with an easy-to-dry cleaning solvent and remove the solvent residue with filtered air.

2) Clean all the pipes of the system, and in some cases, the pipes and joints need to be impregnated.

3) Install oil filter in the pipeline to protect the oil supply line and pressure line of the valve.

4) Install a flushing plate on the collector to replace the precision valve, such as electro-hydraulic servo valve, etc.

5) Check whether all the tubing are the right size and whether the connections are correct.

If the electro-hydraulic servo valve is used in the system, the author may wish to say a few more words, the servo valve has to flush the plate so that the oil can flow from the oil supply pipeline to the collector, and directly return to the oil tank, so that the oil can flow repeatedly, in order to flush the system, let the travel oil filter filter out the solid particles, during the flushing process, do not check the oil filter every 1 2 hours, in case the oil filter is blocked by pollutants, do not open the bypass at this time, if you find that the oil filter begins to block, change the oil filter immediately.

The flushing cycle is determined by the structure of the system and the degree of contamination of the system, if there is no or very little foreign contaminants in the sample of the filter medium, a new oil filter is installed, the flushing plate is removed, and the valve is installed!

Planned maintenance: Establish a regular maintenance system for the system, and recommend a better maintenance system for the hydraulic system as follows:

1) Check and replace the oil filter for up to 500 hours or three months.

2) Regularly flush the inlet oil filter of the oil pump.

3) Check that the hydraulic oil is acidified or polluted by other pollutants, and the smell of the hydraulic oil can roughly identify whether it has deteriorated.

4) Repair leaks in the system.

5) Ensure that no foreign particles enter the fuel tank from the ventilation cap of the fuel tank, the plug seat of the oil filter, the tightly matched ballast seal gasket of the oil return pipeline and other openings of the fuel tank.

Summary. If the clothes are stained with stubborn oil stains, you can refer to the following methods to clean: 1. When the clothes are dry, apply the original solution of the special laundry detergent for hand washing with Blue Moon to the stains, completely cover the stains, and let it stand for 5 minutes (you can gently scrub it), add Blue Moon laundry detergent for regular washing; 2. If the stain cannot be removed after the above methods, (1) pure white cotton, linen, and polyester clothing

Add blue moonshine and white clothes for color stains in every half basin of water (about 2 liters).

If the clothes are stained with stubborn oil stains, you can refer to the following methods to clean: 1.

If the stain cannot be removed after the above methods, (1) pure white cotton, linen, and polyester clothing: add blue moonshine and white clothing stains to each half basin of water (about 2 liters).

Net (600g specification) 1 bottle cap (40g), stir well, soak in clothes for 30min, rinse well. * If the color stain is not removed after 2 hours, take out the clothes, add white clothes to the basin (add 1 bottle cap per half basin of water), stir well, put in the clothes and continue soaking, the cumulative soaking time is not more than 6 hours. (2) White clothing of colored or other materials

Put the clothes into the basin, stick the stain to the bottom of the basin, measure 1 4 caps (10 grams) of colored clothes and 1 4 caps (10 grams) of blue moon collar with blue moonlight color clothes (600g specification) bottle caps, pour them on the stains, cover the stains with other non-stained parts of the clothes, prevent air drying, let stand for 2 hours, and rinse clean. If the stain remains unremoved after 2 hours, it can be left on for an extended period of time overnight.

This machine includes a special gear pump driven by a motor, which has the characteristics of low noise, strong self-priming ability and smooth operation. The high-pressure pipeline is equipped with overflow protection device, which can effectively protect the safety of the hydraulic system. Thermal relay protection is used to prevent motor damage caused by motor overload.

The suction port coarse filter protects the oil pump and prolongs the life of the main filter. There are two stages of fine filter behind the pump, so that the oil can quickly reach a high level of cleanliness. The fine filter can be selected according to the different needs of users to achieve the desired results.

The oil filter housing has a quick-open structure, which allows the upper cover to be opened quickly and quickly without any tools, and the filter element can be replaced. A pressure gauge is mounted on the panel that continuously indicates the health of the system and the degree of contamination of the filter element while working. How it works:

When the oil purifier is working, the polluted oil enters the heater through the inlet under the action of vacuum suction at outside atmospheric pressure, and the heated oil enters the primary filter, and the large particles of impurities are filtered out, and then the oil enters the vacuum separator and flows through the special divergent device. The divergent device creates a large surface area per unit volume of oil, exposing the contaminated oil to an atmosphere with very low relative humidity, thereby removing water, air and gases from the oil. The mixed gas formed by the evaporated water vapor and gas is condensed into a liquid through the water tank and cooler, and enters the water reservoir together, and the remaining gas is pumped out by vacuum.
