Guatemala hydraulic cylinder,self-locking hydraulic cylinder manufacturer,self-locking hydraulic cylinder(Guatemala self-locking hydraulic cylinder,produced by Hengyu Group)
self-locking hydraulic cylinder are widely used in Guatemala,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed self-locking hydraulic cylinder for customers from Guatemala.
If it is found that the self-locking hydraulic cylinder lubrication is poor or the self-locking hydraulic cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the self-locking hydraulic cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the self-locking hydraulic cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the self-locking hydraulic cylinder center line. In this way, when the piston works in the self-locking hydraulic cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the self-locking hydraulic cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.
When installing the self-locking hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the self-locking hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the self-locking hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the self-locking hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the self-locking hydraulic 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.
We can not just consider the price and ignore the quality when we purchase the self-locking hydraulic cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the self-locking hydraulic cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the self-locking hydraulic cylinder is not required.
self-locking hydraulic cylinder to reasonable use of hydraulic oil: strict hydraulic oil selection off. Hydraulic oil is selected in strict accordance with oil standards. The selection of good quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When choosing the oil, it should be selected according to the lowest temperature in different regions, and fill the hydraulic oil according to the dipstick standard, and at the same time, it should also keep the hydraulic system clean (when filling the hydraulic oil, it should prevent the water and other impurities into it), and often check the oil quality, oil level and oil color of the hydraulic oil. If blisters and bubbles are found in the hydraulic oil. When the oil becomes milky white, the source of the air in the oil should be carefully found and eliminated in time.
When the cylinder is tested, why can't the pressure be maintained with the balance valve?
Because the oil into the oil chamber through the hydraulic lock on the control oil circuit through the other side of the spool, the original valve is designed in this way. It locks the circuit after the oil supply circuit loses pressure, on the contrary, if you keep supplying pressure, it is always in the state of opening the other side of the one-way spool. So this valve can't be used in the test.
Hydraulic cylinder performance requirements?
Hydraulic cylinder performance requirements: hydraulic cylinder is the hydraulic system to achieve energy transfer, conversion and control of the working medium, in addition, it is also responsible for the lubrication of the system, rust prevention, corrosion prevention and cooling. The performance of hydraulic oil will make the system flexible, accurate and reliable. Hydraulic performance requirements are determined according to the design parameters of the hydraulic system, operating conditions, the structure of the hydraulic pump and the working environment. Appropriate viscosity and good viscosion-temperature performance Viscosity is an important performance indicator of hydraulic pressure, which has an important impact on the smooth operation of the hydraulic system and the friction parts. The low temperature performance of hydraulic oil includes three aspects: low temperature flow, low temperature start-up and low temperature pumping.
