The quality of the hydraulic pipe supporting the original car is very good, generally it is the rubber tycoon ~ like Parker ~ Gates ~ Goodyear ~ Bridgestone to Michelin ~ etc., the quality is not said, the factory production, the buckle tube machine is also the professional grade of the lower map is
So the hydraulic pipe maintenance of the original car can be used for a long time ~ in the pressure of the pipe in the pressure of the general also more than 1 years, Italy imported pipes can be used for a long time. The pressure is not good for a few days.
Theoretically speaking, the most prone to burst on the general vehicle is the four layer steel wire high pressure pipe with an outer diameter of 42 and 32.
Because the larger the inner diameter of a tube is, the larger the area of force will be and the higher the probability of burst. This point to the specialized pressure excavator high pressure pipe shop turn around to know, they kind of tube preparation, that kind of tube often explode ~! Ha ha.
Maintenance of hydraulic pipe
The most important thing is that drivers should be gentle when doing their work.
I have said that the gear pump and the plunger pump all have oil pulsation during the work of the pump. This pulsation will cause the high frequency vibration of the hydraulic pipe, which can not be completely eliminated.
So the hydraulic pipe has a special protection ring outside. There are both pipes (plastic sleeves) and pipes with small arms (steel wire sleeves) on the main arm of the arm. This protective sleeve works very well.
And the pipe clip, I met a car broken steel pipe always burst, changed a few roots, his pipe clip is the hammer of the steel plate made of the clamp, the steel pipe will be worn to the owner and do not understand the pipe and change tube, then I let the owner clamp the scrap tire skin, it was done.
Try not to let the hose contact with gasoline and diesel, although it is oil resistant, but still corrosive, general rubber in long soaked gasoline and diesel will bulge and fluffy.
And the central oil distributor and the motor cover must be cleaned regularly, then use 2 calcium based grease to coat the protective layer, and the buckle pipe should also be smeared. The rust is in trouble, especially in the coastal areas. We have a car owner do not understand, in the sea with steel plate work, the last walk the motor pipe good, the buckle pipe at the end of the pipe rust through the tube directly squeezed out, moving, the tide, the car climbed the sea for more than 1 months to get up.
And excavator pipe, installation must pay attention to ~ must add the rod to tighten the flange type general addition and dismantling screw glue. Not tightened, vibration loose oil is a small thing, if the vibration and wear interface plane is troublesome to the lower map is two wear, oil seal less than 1 hours to be finished, grinding the uneven, and finally replaced to the good.
What's the choice of a pipe store?
There is no diamond without porcelain. Unfortunately, many diamonds do not want to earn money.
Buckling machine is very important, generally produced in Handan, Shanghai is good, of course, imports are better, as long as the pressure is enough, there is no problem. It is rare to use this type of computer in China.
First of all, several pipes are cut below.
This is the same as the electric saw! This will produce dust and steel wire easy to scatter.
The following is the product description
The suction pipe cutting machine is a special equipment used for cutting rubber tubes. In principle, high carbon steel material can be used to produce high carbon steel material. It produces high temperature in cutting rubber tube and rapidly cooling at high speed, so that the blade of the circular steel sheet produces very high hardness to achieve the purpose of safe and efficient cutting. The machine is characterized by straight cutting section, loose wire head and dust absorption.
There is also the peeling shop to cut the shop directly with the knife carving a moment.
Preloading is usually done without preloading machines. Pre installed machines are used for mass production. There is no problem with manual work, as long as the length of pre load is enough.
Note that this tube is not used for peeling machine, resulting in oil leakage at the pressure point.
It's too cold last night. There's another important thing.
That is to press the pipe to clean up ~ the last time to improve the water and land dual-use excavator (change the hydraulic pipe to the ship) to press two walking motors, the pressure pipe has no cleaning machine, the rear motor does not move directly, and they do not move for half a day, or do not turn. Scraps, quickly let them remove the pipe and clean it with hydraulic oil. Finally, it still doesn't move. It is probably the brake there. Remove the shell back to the oil pipe and flow out a lot of rubber debris from the motor shell. After a bucket of oil, the motor moves! Four uncle halo scolded the pipe.
There are special cleaning machines in the appendix. Some are cleaning and testing.
Notice that if a new car is best used for No. 46 hydraulic oil,
Work for more than ten thousand hours, usually in order to ensure that the excavator work intensity, will use 68 hydraulic oil. Because all kinds of valve working devices of hydraulic pumps have different degrees of wear and tear, high viscosity hydraulic oil can keep pressure up, but it also improves the burst rate of hydraulic pipes.
This can be chosen according to the actual situation.
