(Kuwait trunnion cylinder,produced by Hengyu Group）

trunnion cylinder are widely used in Kuwait，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed trunnion cylinder for customers from Kuwait.

Introduction to trunnion cylinder:

If it is found that the trunnion cylinder lubrication is poor or the trunnion cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the trunnion cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the trunnion cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the trunnion cylinder center line. In this way, when the piston works in the trunnion cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the trunnion cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

When the trunnion cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.

trunnion cylinder and hydraulic station selection: Select the type and structure of the trunnion cylinder according to the operation requirements of the main engine. According to the external load force borne by the trunnion cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the trunnion cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the trunnion cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the trunnion cylinder, the diameter of the piston and the piston rod.

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.

Answers to some questions about trunnion cylinder:

Two cylinders in parallel, how to solve the synchronization problem?
The following methods can be used to achieve parallel cylinder synchronization: 1, rigid mechanical synchronization. 2. The throttle valve or speed regulating valve is used in the circuit to adjust the synchronization. 3, the two cylinders use independent quantitative pump oil supply to achieve synchronization. 4. Synchronous motor is used in the loop to realize cylinder synchronization. 5, using the position sensor to measure the stroke position and control the cylinder synchronization through the electrical system.

What is the main maintenance of the cylinder?
After disassembling the cylinder: 1, clean the cylinder and piston; 2, replace all seals; 3, if there is a valve to repair, to ensure sealing and flexible; 4, deal with all deformation parts; 5. Installation experiment.
