Bangladesh push and pull the cylinder

(Bangladesh push and pull the cylinder,produced by Hengyu Hydraulic Cylinder Factory)

push and pull the cylinder are widely used in Bangladesh,because of no need for deceleration device,long service life,smooth movement.So our company has designed push and pull the cylinder for customers from Bangladesh.

Introduction to push and pull the cylinder:

When the push and pull the cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the push and pull the cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

When producing oil push and pull the cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

The method of sleeve push and pull the cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the push and pull the cylinder can be significantly improved by rolling in the finishing of the inner holes of the push and pull the cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

In the process of using the push and pull the cylinder, sometimes such a problem will occur, the push and pull the cylinder can not act immediately after the instruction of the push and pull the cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil push and pull the cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

Answers to some questions about push and pull the cylinder:

What are the four cylinders of the truck crane?
The four cylinders of the truck crane generally refer to the telescopic cylinder of the boom (to adjust the length of the boom), the variable amplitude cylinder of the boom (to adjust the elevation Angle of the boom), the horizontal telescopic cylinder of the support leg and the vertical cylinder of the support leg.

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.
