(Poland trunnion cylinder,produced by Hengyu Hydraulic Co., Ltd）

trunnion cylinder are widely used in Poland，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed trunnion cylinder for customers from Poland.

Introduction to trunnion cylinder:

When producing oil trunnion 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.

Because of the slightly complex structure of the buffer trunnion cylinder, sometimes there will be problems, such as when the trunnion cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

The piston rod of the trunnion 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 trunnion cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the trunnion cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The trunnion cylinder is basically composed of trunnion cylinder and trunnion cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.

Answers to some questions about trunnion cylinder:

What is the function of the forklift truck cylinder and how does it work?
(1) In order to quickly and conveniently pick up the goods, the gantry needs to be tilted forward; In order to prevent the goods from falling, the door frame should be tilted backward to ensure the stability of the goods. The front and back tilt of the frame is accomplished by tilting the oil cylinder. (2) The inclined cylinder is composed of a piston, a cylinder block, a piston rod, an upper cover, a lower cover, a compression nut and a cover female and other main parts. (3) The inclined cylinder has two oil holes that can be interchanged into oil inlet and discharge holes. The cylinder is divided into a front cavity and a back cavity by a piston. The back cavity is filled with high-pressure oil when it tilts forward, and the front cavity is filled with high-pressure oil when it tilts backward.

How many kinds of cylinder seal repair kit are there?
Very much, a wide variety of imported and domestic, J type, UHS, DHS, O-ring, Sterseal, etc., as well as support bars, materials are different, according to the size of the pressure selection is different, the appearance of the structure is different, the size is a variety, maintenance is generally selected according to the needs of the cylinder.
