Internal structure and movement mode of rodless cylinder

Promulgator : DIHAO Date : 2019-01-11

The OSP Rodless Cylinder is mainly used to connect the external actuator to the piston rod and follow the reciprocating motion of the piston. The biggest advantage of this cylinder is that it saves space. Mechanical contact rodless cylinders are also commonly referred to as contact rodless cylinders. The cylinder head has a groove on its axis. The piston and slider move at the top of the groove.

In order to prevent the leakage and dust accumulation of the OSP Rodless Cylinder, polyurethane sealing belt and dust-proof stainless steel belt should be used at the opening to locate them at both ends of the cylinder head. The piston carrier passes through the groove and connects the piston to the slider. Is the piston connected to the slider? The reciprocating motion of the actuator fixed on the slider begins. The characteristics of this cylinder are:

Compared with ordinary cylinders, the use of M-type OSP Rodless Cylinder can reduce the installation position by 1/2. No anti-clearance mechanism is required; for a large stroke of 7 meters with a diameter of 10 to 80 mm and a maximum of 40 mm; for a standard model, the speed is 0.1 to 0.5 meters per second; for a high speed, it is 0.3 to 3 meters per second: poor sealing performance and easy to leak. Medium pressure must be used when using three valves; in order to increase load capacity, small load capacity must be added.

How to Correctly Eliminate Abnormal Phenomena in Cylinder

When the piston head and cylinder head are knocked, the sound produced by the collision is that when the engine runs between the air cylinder actuator and the cylinder head, it will make a very clear knocking sound, and the cylinder head will be accompanied by vibration. Usually this happens when crankshaft bearings or connecting rod bearings or piston pin holes are badly worn. The reason is that when the top of the piston moves up and down, the top of the piston will impact the valve cover. Secondly, the piston has reached a certain height because of the quality of manufacturing or the use of accessories.

The elimination method is to remove the air cylinder actuator head to check whether there is a collision, and replace it according to the qualified products and supporting parts. The cylinder liner can also be increased appropriately, and the cylinder head can be increased without collision. If the cylinder head is seriously worn out, the damaged place should be repaired or replaced. When the piston head collides with the valve, it only appears on the upper valve engine. When the upper cylinder collides with the air cylinder actuator head, the rhythm can be heard. As the engine speed increases, the noise will increase.

The reason for this problem is that the adjusting bolt on the rocker arm tightens the locking nut, changes its normal operation after vibration, reduces the valve clearance, contacts the check point of the exhaust stroke piston with the valve head, or the assembly force between the sprockets.

If the stem and tube dimensions are not good enough. Then the metal will stagnate after heating, or the coefficient of expansion will be too large. The method of judging and eliminating is to first determine which valve collides by removing the valve cover, contacting or maintaining the rocker arm and stepping on the starting bar. If there is obvious vibration on the rocker arm axis, or if the hand touches the arm, the valve can be judged whether there is a collision phenomenon. At this point, determine the cause or adjustment, and then lock the nut. Check assembly marks of timing sprockets and flywheels. Among other reasons, repair or replacement of suitable accessories should be carried out.
