(Congo sanitation truck hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

sanitation truck hydraulic cylinder are widely used in Congo，because of no need for deceleration device，long service life，smooth movement.So our company has designed sanitation truck hydraulic cylinder for customers from Congo.

Introduction to sanitation truck hydraulic cylinder:

Do not regularly check the damage of the chrome layer of the sanitation truck hydraulic cylinder: completely extend the sanitation truck hydraulic cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the sanitation truck hydraulic cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the sanitation truck hydraulic cylinder seal. Welding slag is strictly prohibited on the surface of the sanitation truck hydraulic cylinder.

Under normal circumstances, the sanitation truck hydraulic cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the sanitation truck hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the sanitation truck hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the sanitation truck hydraulic cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the sanitation truck hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

The piston rod of the sanitation truck hydraulic cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

The difference between the integral sanitation truck hydraulic cylinder and the split sanitation truck hydraulic cylinder: The integral sanitation truck hydraulic cylinder and the split sanitation truck hydraulic cylinder in the sanitation truck hydraulic cylinder are two different sanitation truck hydraulic cylinders, and they are very different. The whole sanitation truck hydraulic cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split sanitation truck hydraulic cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and sanitation truck hydraulic cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

Answers to some questions about sanitation truck hydraulic cylinder:

What components can control cylinder rising and falling speed and the speed is adjustable?
A throttle or special solenoid valve is required. The reversing valve can choose the three-position reversing valve with P-type middle function. When rising, the reversing valve can be changed to the middle position to achieve differential connection and the fastest speed. Add a combination valve one-way throttle valve in the oil return circuit, connection mode: when the cylinder rises, the oil flows back to the tank through the check valve, the throttle valve is reversed off, when the cylinder falls, the reversing valve is changed to the left or right position (see the structure of the valve), the check valve is reversed off, the oil returns to the tank through the throttle valve, and the speed can be adjusted through the throttle valve.

What is the function of the hinged cylinder of the shield machine?
The articulated cylinder is used for the shield when the radius of curvature is very small during the propulsion process, that is, for turning. For example, a propulsion section with a radius of curvature of R150 can only be turned using an articulated system due to the sensitivity of the shield body (i.e. the length of the shield body divided by its outside diameter). However, in the construction process, the use of articulated systems is not much.
