(Ecuador trunnion cylinder,produced by Hengyu Group）

trunnion cylinder are widely used in Ecuador，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed trunnion cylinder for customers from Ecuador.

Introduction to trunnion cylinder:

When the trunnion cylinder is in use, ensure that the trunnion cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.

When the trunnion cylinder needs to be stored for a period of time, please follow the recommended methods: The trunnion cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the trunnion cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil trunnion cylinder should not be in direct contact with water vapor for a long time. The trunnion cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the trunnion cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the trunnion cylinder Before working, the trunnion cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the trunnion cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

Under normal circumstances, the trunnion 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 trunnion cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the trunnion cylinder and the end cover, the piston and the piston rod, the piston and the trunnion 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 trunnion cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

If the trunnion cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.

Answers to some questions about trunnion cylinder:

How to distinguish the bucket cylinder from the bucket rod cylinder?
It can be distinguished according to its installation and connection: one end of the bucket cylinder is connected with the bucket; The rod cylinder is not connected to the bucket. The bucket refers to the bucket installed on the excavator. According to the working mode, it is divided into backhoe bucket and shovel bucket, the backhoe bucket is commonly used. The boom and bucket rod are working device of the excavator, usually called the big arm and the forearm, which are mainly used to control the digging and loading of the bucket. The arm connected to the frame is longer, so it is commonly known as the big arm, and its term is called the boom. The arms connected to the digging bucket are smaller, so they are commonly known as the lower arms, and the term is called the bucket rod, so they are commonly known as the big lower arms.

By what means can the hydraulic system control the arbitrary stroke position of the rotary cylinder piston rod?
The following ways can be considered: 1, through the limit device, such as limit switch, position sensor, etc. 2, by feedback the pressure of the hydraulic oil in the cylinder. The load determines the pressure, the pressure in the cylinder is determined by the load, and the pressure is very small when the cylinder is unloaded. 2.1 When clamping the workpiece, the pressure of the cylinder increases, by calculating the relationship between the clamping force and the pressure of the cylinder, take a pressure value of the cylinder, set the pressure switch, and drive the valve to work when the pressure reaches the preset value, so that the oil circuit stops supplying oil. 2.2 or set the pressure value of the relief valve to overflow after a certain set pressure.
