The speed ratio refers to the same flow (volume of liquid entering the hydraulic cylinder per unit time), Jinan Hydraulic machinery Price The ratio of the piston rod extension speed to the retraction speed. The calculation is equal to the inverse ratio of the large cavity area and the small cavity area of the cylinder. The speed ratio is related to the cylinder diameter and rod diameter of the oil cylinder. Main products: harvesting machinery series Jinan Hydraulic machinery Flip plow series, press series, grader series, TGL, HG, SG, DG series vehicle oil cylinder, HSG series engineering oil cylinder mining machinery, ship oil cylinder, and various non-standard oil cylinders. Welcome to order!
Compared with mechanical transmission, hydraulic cylinder transmission is a new transmission form. Hydraulic transmission has a history of more than 200 years since the birth of hydraulic press, but hydraulic transmission has been going on for many years. Especially after the 1960s, with the development of atomic energy science, space and hydraulic technology, Jinan Hydraulic machinery It permeates all fields of the national economy, including agricultural machinery, automobiles, light textile, shipbuilding, petroleum, aviation and machine tool industries, Jinan Hydraulic machinery Price Hydraulic technology lists some application examples of hydraulic and pneumatic transmission.
Because the hydraulic cylinder must bear a great pressure, the heavier the load, the greater its pressure will be. Therefore, the maintenance of the hydraulic cylinder is the most important part of the maintenance of the entire hydraulic system. The hydraulic cylinder is the heart of the hydraulic system. It is difficult to repair a heart problem, so the maintenance of the hydraulic cylinder should be careful. first, Jinan Hydraulic machinery Rust prevention is required. Because the piston part of the hydraulic cylinder will extend out of the cylinder in the working state, it will naturally suffer from oxidation Jinan Hydraulic machinery Price The erosion of acid gas requires us to apply proper amount of grease to protect it.
The failure of the hydraulic cylinder due to improper design and manufacture is because the oil pressure cannot act on the effective working area of the piston when the piston travels to the end point and returns, or the effective working area is too small when starting, which causes problems. When the transverse load of the hydraulic cylinder is too large, the force is not strong or the cylinder is bitten, the same consequences will occur. Jinan Hydraulic machinery Therefore, when installing the hydraulic cylinder, the axis position of the cylinder must be consistent with the movement direction; Jinan Hydraulic machinery Price And ensure that the load borne by the hydraulic cylinder passes through the cylinder axis as far as possible without eccentricity, so that the problem can be solved.
1. 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 in the pressure holding state is consistent with the initial setting. Check the hydraulic oil and suction oil filter before measuring the pressure, Jinan Hydraulic machinery Replace or clean it. Secondly, check the main overflow valve of the reversing control multi way valve to see if it is damaged or blocked by foreign matters, Jinan Hydraulic machinery Price Clean it. If your pump is a gear pump, the problem should be minor in general. 2. Next, let's look at the traffic problem.
Fluid cleanliness. The cleanliness of the system oil will have a very important impact on the hydraulic cylinder. Hydraulic shock and vibration hydraulic cylinders will be affected by the performance of components, pipeline and medium characteristics, etc., which will be accompanied by hydraulic shock and vibration. Generally speaking, if the oil temperature is too high or too low, Jinan Hydraulic machinery Price Will have a great impact on the working efficiency of the hydraulic cylinder. If the oil temperature of the hydraulic cylinder is too high or too low, the physical and chemical properties of the medium will change, Jinan Hydraulic machinery As a result, the viscosity of the working medium decreases or the possibility of leakage increases.
