(Latvia tailplate hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to tailplate hydraulic cylinder:

tailplate hydraulic cylinders in series, parallel and series parallel. Series: In the tailplate hydraulic cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the tailplate hydraulic cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the tailplate hydraulic cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the tailplate hydraulic cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.

Protection of the tailplate hydraulic cylinder surface: During the dismantling process, safety protection should be carried out on the tailplate hydraulic cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the tailplate hydraulic cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the tailplate hydraulic cylinder should be cleaned up in time.

If the tailplate hydraulic cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the tailplate hydraulic cylinder. The internal parts of the tailplate hydraulic cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, and the action resistance is too large, so that the piston speed of the tailplate hydraulic cylinder changes with the different stroke position, and there is slip or crawl. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the tailplate hydraulic cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings. At the same time, check whether the lubrication is good or whether the tailplate hydraulic cylinder bore processing is out of whack. Because the piston and tailplate hydraulic cylinder, guide rail and piston rod are relative If the tailplate hydraulic cylinder is crawling seriously, check whether air has entered the hydraulic system. Air compression or expansion can cause the piston to slip or crawl. The exclusion measures are to check the hydraulic pump, set up a special exhaust device, and quickly operate the exhaust several times in the full stroke. Check the seals at the same time, because the quality of the seals is directly related to slippage or crawling. When the O-ring is used under low pressure, compared with the U-ring, it is easy to slip or crawl because of the higher surface pressure and the larger difference between static and static friction resistance. The surface pressure of the U-shaped sealing ring increases with the increase of pressure, although the sealing effect is correspondingly improved, but the difference between static and static friction resistance is also larger, the internal pressure increases, affecting the rubber elasticity, due to the increase in the contact resistance of the lip, the sealing ring will tip over and the lip elongation, and it is also easy to cause slip or crawling tailplate hydraulic cylinder weight composition and calculation. The weight of the tailplate hydraulic cylinder is composed of the tailplate hydraulic cylinder diameter, the outer diameter and weight of the tailplate hydraulic cylinder, the rod diameter, and the weight of the accessories, so in calculation, it is to add all these together to get the specific value. However, if there are special circumstances, it may be calculated separately. This work can be carried out by yourself, but it can also be carried out by professionals, so that mistakes can be avoided.

The main role of the tailplate hydraulic cylinder: the tailplate hydraulic cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the tailplate hydraulic cylinder realizes reciprocating motion. The structure of the tailplate hydraulic cylinder has three categories: piston tailplate hydraulic cylinder, plunger tailplate hydraulic cylinder, swing tailplate hydraulic cylinder, piston tailplate hydraulic cylinder and plunger tailplate hydraulic cylinder to achieve reciprocating linear motion, output speed and thrust, swing tailplate hydraulic cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the tailplate hydraulic cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The tailplate hydraulic cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

Answers to some questions about tailplate hydraulic cylinder:

Why does the tipping bucket cylinder have a cylinder withdrawal problem?
This problem may have a certain relationship with the operation of the driver, the main reasons are the following two situation analysis: 1, the current domestic loader working device is mostly a six-link mechanism, the six-link mechanism in the bucket to the limit position, lift the boom, the rotating bucket cylinder will appear "cylinder pulling" phenomenon, that is, the piston rod of the rotating bucket cylinder will be pulled out. In this case, in order to protect the cylinder, a pressure overload protection valve with large and small cavities is provided on the multi-way valve rotating bucket link (large chamber 18MPa, small chamber 12MPa). 2, before the cylinder is assembled to the whole machine, the cylinder is not limited, the piston rod of the cylinder can be pulled in place before and after, but when it is installed on the whole machine, in order to avoid the cylinder pulling out, the limit switch is installed according to the regulations.

How to distinguish cylinder rod head and cylinder bottom?
One end of the piston rod can be telescopic is the rod head, and the one behind is the bottom of the cylinder, which is the single rod cylinder.
