Puerto Rico Lifting cylinder

(Puerto Rico Lifting cylinder,produced by Hengyu Hydraulic Co., Ltd)

Lifting cylinder are widely used in Puerto Rico,because of high work efficiency,long service life,smooth movement.So our company has designed Lifting cylinder for customers from Puerto Rico.

Introduction to Lifting cylinder:

The Lifting cylinder should be vented: when the Lifting cylinder is installed or parked for a long time to work again, the air will penetrate into the Lifting cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the Lifting cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the Lifting cylinder, the oil is best entered and discharged from the highest point of the Lifting cylinder. Lifting cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

Before purchasing the Lifting cylinder, it is necessary to master the original information and design basis, mainly including: the use and working conditions of the machine; The structural characteristics, load conditions, stroke size and operation requirements of the working mechanism; The selected working pressure and flow of the hydraulic system; The reality of materials, fittings and processes; Relevant national standards and technical specifications, etc.

Lifting cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards Lifting cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the Lifting cylinder guide is determined by the length of the stroke. Check the strength of Lifting cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

The body of the Lifting cylinder on the processing process requirements: the body of the Lifting cylinder is an important and essential part of the Lifting cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the Lifting cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

Answers to some questions about Lifting cylinder:

How to select the propulsion cylinder according to the shield attitude, cylinder stroke, shield tail clearance and other factors?
Generally, the shield machine will be equipped with the corresponding cylinder. Soil pressure balancing machine, mud water balancing machine have the corresponding cylinder, there will be no insufficient cylinder force. In the jacking process of the pipe jacking machine, there are certain requirements for the jacking force of the cylinder.

What are the reasons why the hydraulic cylinder action is slower than normal?
There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system under the pressure state is consistent with the initial setting. Before measuring the pressure, it is best to check the hydraulic oil and suction oil filter and replace or clean it. Second, check the main relief valve of the reversing control multiway valve to see if there is damage or foreign matter blocking, and clean it. If your pump is a gear pump, the problem should generally be small. Second, look at traffic. There is no leakage in the cylinder, leakage in the reversing valve spool and so on.
