self-locking hydraulic cylinder are widely used in Belarus，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed self-locking hydraulic cylinder for customers from Belarus.

Introduction to self-locking hydraulic cylinder:

The repair method of the self-locking hydraulic cylinder: the repair of the self-locking hydraulic cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.

self-locking hydraulic cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the self-locking hydraulic cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

The self-locking hydraulic cylinder is mainly composed of body, piston, piston rod, self-locking hydraulic cylinder head, self-locking hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the self-locking hydraulic cylinder into two chambers, and moves reciprocally in the self-locking hydraulic cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the self-locking hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the self-locking hydraulic cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the self-locking hydraulic cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the self-locking hydraulic cylinder bottom and the self-locking hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the self-locking hydraulic cylinder The working medium of the self-locking hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; self-locking hydraulic cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the self-locking hydraulic cylinder: The buffer structure of the self-locking hydraulic cylinder is to prevent the piston from colliding with the self-locking hydraulic cylinder head at the end of the stroke.

The self-locking hydraulic cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure self-locking hydraulic cylinder can use 20 steel pipe, and the high pressure self-locking hydraulic cylinder can use 45 steel pipe.

Answers to some questions about self-locking hydraulic cylinder:

How is the hydraulic cylinder selected in the mechanical design manual?
First of all, it is necessary to meet your work needs, and the second is to meet the structural space of the cylinder and accessories. Three to consider the other parameters of the cylinder.

Why can't the hydraulic cylinder be pulled back after pushing to the limit?
May be long-term use to the limit position, resulting in serious wear caused! The solution is to add the stroke switch or disassemble and add gaskets before and after the piston.
