Britain garbage truck hydraulic cylinder

(Britain garbage truck hydraulic cylinder,produced by Hebei Hengyu company)

garbage truck hydraulic cylinder are widely used in Britain,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed garbage truck hydraulic cylinder for customers from Britain.

Introduction to garbage truck hydraulic cylinder:

In order to ensure the service life of the garbage truck hydraulic cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.

The viscosity of the working oil used in the garbage truck hydraulic cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

garbage truck hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching garbage truck hydraulic cylinder block - fine boring garbage truck hydraulic cylinder block - grinding garbage truck hydraulic cylinder block. The rolling method is: broaching garbage truck hydraulic cylinder block - fine boring garbage truck hydraulic cylinder block - rolling garbage truck hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the garbage truck hydraulic cylinder block is about 1-2 days, rolling 1 meter of the garbage truck hydraulic cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the garbage truck hydraulic cylinder increases by 25%. If the garbage truck hydraulic cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality garbage truck hydraulic cylinders, you must take the rolling production process. After the garbage truck hydraulic cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

The material, shape and compression of the garbage truck hydraulic cylinder seal have a great impact on the service life and work efficiency of the garbage truck hydraulic cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.

Answers to some questions about garbage truck hydraulic cylinder:

Design a hydraulic cylinder, the inner diameter of the cylinder is 100mm, what size of piston rod is best used?
This involves how much speed ratio you need, that is, the area ratio of the rod cavity and the rodless cavity, if the weight is relatively large, it is recommended that the speed ratio choose 2, that is, the piston rod diameter choose 70mm, under normal circumstances, the speed ratio choose 1.46, the piston rod diameter choose 55mm. Of course, there are many factors that affect the diameter of the piston rod, such as stroke, stroke is too long, in order to stabilize the work of the hydraulic cylinder, its diameter also needs to choose a relatively large, sometimes even non-standard products, need to choose according to the actual situation.

How does the self-locking cylinder work?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil circuit itself is equipped with a valve to maintain pressure, so that the hydraulic oil of the cylinder does not return to the tank, and the oil chamber of the cylinder is filled with a certain pressure of oil. However, this pressure holding self-locking is not very safe and reliable, and the plunger will slowly return if there is a leak. Mechanical self-locking is to install a nut on the plunger of the cylinder, and when the cylinder rises to the required position, the nut on the cylinder plunger is rotated to the end, and the cylinder block is in contact, so that the plunger will be fixed to the required height. When it is necessary to relieve the pressure, screw the nut on again and let the plunger return to the position. This kind of cylinder has a special name, called self-locking hydraulic cylinder.
