The oil cylinder shall be assembled in a special workshop or assembly area, and the temperature shall be kept at 20~250C, Tangshan Hydraulic cylinder manufactor It shall be far away from the tuyere, dust and cutting area, with fresh air, no dust and no noise; Avoid direct glare. The assembly room shall be equipped with installation platform, sufficient working position apparatus, assembly turnover vehicle Tangshan Hydraulic cylinder Lifting and hoisting equipment and the following special basic equipment. a: Cylinder loader; b: Another cylinder cleaning machine is used to heat and clean another part; c: Pressure test equipment, used for pressure test of oil cylinder; d: The air duct is used to clean and dry the other parts after cleaning.
Because the hydraulic cylinder has to bear a great pressure, the heavier the load, the greater its pressure will be. Therefore, the maintenance of the hydraulic cylinder is an important part of the maintenance of the entire hydraulic system. The hydraulic cylinder is the heart of the hydraulic system, Tangshan Hydraulic cylinder It is difficult to repair the heart problem, so the maintenance of the hydraulic cylinder should be careful. First, rust prevention. Because the piston part of the hydraulic cylinder will extend the cylinder in the working state, Tangshan Hydraulic cylinder manufactor Naturally, it will be corroded by oxide and acid gas, which requires us to coat it with proper grease for protection.
The two lips of the seal have two contact circumferential surfaces. Whether the force on the inner and outer circumferences is evenly distributed means that the force on the two circumferences cannot be zero. If the force on a certain point is zero, the shaft seal has inner and outer lips, Tangshan Hydraulic cylinder The outer lip is installed in the groove to contact the outer wall, and the inner lip is in contact with the piston rod surface. Both lips have an interference amount, which is equal to the generation of two contact circumferential surfaces, that is, the generation of two circumferential rebound forces. How to determine the magnitude of the circumferential force? Both the inner and outer lips of the seal have two chamfers. Since the interference of the same inner and outer lips is certain, Tangshan Hydraulic cylinder manufactor The angle of the chamfer determines the size of the circumferential area of the inner and outer contact of the two lips.
The speed ratio refers to the same flow (volume of liquid entering the hydraulic cylinder per unit time), Tangshan Hydraulic cylinder manufactor 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 Tangshan Hydraulic cylinder 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!
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, Tangshan Hydraulic cylinder 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, Tangshan Hydraulic cylinder manufactor 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.
