Hydraulic support jack quotes, Jilin hydraulic support jack, Big Star Coal Mine Machinery good quality

Big Star Coal Mine Machinery for you to introduce low-pressure cylinders: 16Mpa under pressure in the hydraulic cylinder is called the low-pressure cylinder, which is widely used bulldozers, loaders, graders and cranes and other construction machinery. Such cylinder seal oil and rubber at home and abroad is often used as the material hydraulic support jacks offer, such as nitrile rubber, rubber cloth and ternary nylon rubber. Since the beginning of the cylinder seal, the outer two parts: the outer seal portion includes static seals and cylinder head cover and the rod guide movement of the seal between the hydraulic support jack procurement cylinder and the cylinder head between the two role is to ensure hydraulic no leakage outside the cylinder; inner sealing portion includes movable seal between the piston and the cylinder and the inner diameter of the piston and the piston rod static seal junction. These sealing performance state is a key determinant of hydraulic cylinders can meet the design capacity. Big Star Coal Mine Machinery on the following seal member assembly when the requirements are described below: (3) before the cylinder head and the piston rod assembly assembly applications gasoline or clean oil (non-diesel or kerosene) Clean all assemblies and head outside the ring The residue tank with a thick cloth or clean, lint-free cloth, before loading the seal, and should be coated with hydraulic oil (non-dry assembly) on the seal and the contact surface of the guide sleeve. Preferably when the cylinder head into the piston rod assembly tooling from the horizontal or vertical direction, to ensure both wholesale concentric rear hydraulic support jack, only lightly scored with a hard stick. Also can be processed when the conditions of a guide sleeve, then with the nut screwed into or hardwood, which not only protect the seal surface, but also to ensure a smooth cylinder head into the cylinder barrel.
