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

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

Introduction to trunnion cylinder:

trunnion cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.

When installing the trunnion cylinder pipe, the pipe should be cleaned after installation, and should not pass through the trunnion cylinder block, and the by-pass pipe must be installed in front of the oil port of the trunnion cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the trunnion cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the trunnion cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

The internal leakage of the trunnion cylinder is an important indicator to measure the quality of the trunnion cylinder: the internal leakage of the trunnion cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the trunnion cylinder, so that the trunnion cylinder can not accurately and stably stop in a certain position of the trunnion cylinder, so it is one of the main indicators of the trunnion cylinder.

When the hydraulic oil is not pumped into the trunnion cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the trunnion cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

Answers to some questions about trunnion cylinder:

Can one hydraulic pump with two cylinders work?
A hydraulic pump with two cylinders will work. Commonly used hydraulic pump types: 1, according to whether the flow can be adjusted can be divided into: variable pump and quantitative pump. The output flow can be adjusted according to the needs of the variable pump, the flow can not be adjusted called quantitative pump. 2, according to the pump structure commonly used in the hydraulic system is divided into: gear pump, vane pump and plunger pump 3 kinds. Gear pump: small volume, simple structure, the cleanliness of the oil requirements are not strict, the price is cheaper; However, the pump shaft is subjected to unbalanced force, serious wear and leakage. Vane pump: divided into double acting vane pump and single acting vane pump. The pump has uniform flow, smooth operation, low noise, higher pressure and volumetric efficiency than gear pump, and more complex structure than gear pump.

What is the smallest cylinder size?
The smallest shape cylinder I have ever seen is a hydraulic clamping cylinder in the machine tool industry. Outer diameter 24 mm, total length 23 mm, travel 4 mm. Weighs 0.05 kg. Maximum clamping force 3500 Newtons.
