Detailed installation method for cylinder seal installation
This method is fast, convenient, and can guarantee the quality of the device. 3 cylinder head adjacent to the internal thread. Since the internal thread of the inner hole of the end face of the cylinder tube is easy to damage the seal member, a thin-walled open guide sleeve must be processed in the device, and the piston is firmly fixed to the piston head so that the piston can be smoothly inserted into the cylinder tube, thereby shielding the seal. The piece also improved the quality of the device. 2. High-pressure hydraulic cylinders With the growth of social productivity, it has become very important to improve the pressure grade. High-pressure miniaturization is increasingly being taken seriously by people. The high-pressure system and the intelligent control system require the hydraulic cylinder to have no surface leakage, low starting resistance, high agility and no crawling and lag signs in the hydraulic cylinder. At present, Hainan has introduced the slip ring sealing skills represented by the combination of American Xiaban, German Baose (now Baoxia Xiaban-recorder) and Honggeer, and it is used in excavators and loading. In high-pressure hydraulic cylinders for engineering machines such as machines and cranes. The accurate device is the condition for the performance and service life of the sealing tube system. The device process is as follows: (1) The seal on the piston The piston sealing device consists of a rectangular slip ring (also called a Glyd ring) and an elastic ring. A 5-way guide ring (also called a friction ring, a support ring or a Sleek ring) is combined. It is used for sealing on heavy duty pistons, has excellent sealing, anti-extrusion and anti-wear properties, and is also highly resistant to corrosion. The seals such as the Glyd Ring must be placed according to the following device process before the air bag is sealed. 1 Push the elastic ring into the clean piston groove with a special taper sleeve. 2 Dip the gram ring into the hydraulic oil (or oil) and heat it to about 80 °C with a simmer, until the feel of the glyph ring has greater elasticity and extensibility. 3 Insert the heated Glyd ring into the piston groove elastic ring with a guide taper sleeve. 4 The inner ring taper elastic sleeve is used to cool and tighten the glyd ring. If the deformation of the Douglas ring is too large and should not be tightened, the piston qualified ring should be placed in a hot oil solution of about 80 °C for about 5-10 minutes. After removal, the device must be tightened to the placement size. The Sly ring should be able to rotate in the piston guiding groove, and the opening gap should have sufficient expansion amount, which is usually determined by the diameter of the piston (2-5mm is appropriate), and the opening position should be placed before the cylinder is installed. Symmetrically staggered. (2) Sealing of the cylinder head The seal of the cylinder head is composed of a double seal and a 2-3 sley ring and a dust seal. The seal is also called the door slip ring, and its accuracy directly affects the outer seal result. The equipment should be meticulous in the process, the parts and seals should be clean, and the lubrication device should be accepted to stop the sharp edges (the whole thread should be covered), and the things should be smooth and burr-free to avoid damage to the seals. The order of the device is as follows: 1 First, insert the O-shaped elastic ring into the combination washer groove in the cylinder head. 2 Then bend the seal that has been heated in the oil into a concave shape, fit it in the inner groove of the O-shaped elastic ring, and pry the bending part into the groove under the hot state (pressed with a wooden handle with a word screw) Shaped), meticulous: the step of the seal should be on the high pressure side.
