Sudan self-locking hydraulic cylinder

(Sudan self-locking hydraulic cylinder,produced by Hebei Hengyu company)

self-locking hydraulic cylinder are widely used in Sudan,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed self-locking hydraulic cylinder for customers from Sudan.

Introduction to self-locking hydraulic cylinder:

When the long-stroke self-locking hydraulic cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in self-locking hydraulic cylinder head seal damage, oil leakage, and piston sleep in the self-locking hydraulic cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the self-locking hydraulic cylinder; The piston and the piston rod are connected with a spherical joint.

self-locking hydraulic cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the self-locking hydraulic cylinder head itself is the guide sleeve of the piston rod, the self-locking hydraulic cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the self-locking hydraulic cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

When the self-locking hydraulic cylinder is installed, the piston and the self-locking hydraulic cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the self-locking hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the self-locking hydraulic cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized self-locking hydraulic cylinders, only careful and careful operation can be avoided.

self-locking hydraulic cylinder use should try to avoid sealing belt into the self-locking hydraulic cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the self-locking hydraulic cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the self-locking hydraulic cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.

Answers to some questions about self-locking hydraulic cylinder:

PLC+ inverter + motor + pump + solenoid valve + cylinder combination, can control the accuracy of cylinder position?
In the case of extremely high accuracy requirements, you can not, please consider a few problems: 1, hydraulic oil can be compressed, it is elastic like a spring. Therefore, in the general hydraulic servo system, the valve control is far more accurate than the pump control. Because the valve can be installed very close to the hydraulic cylinder, or even installed on the hydraulic cylinder, but the pump must go through the tubing and then into the hydraulic cylinder, there is a long distance, which greatly reduces the rigidity of the system and increases the difficulty of control. 2, the quantitative pump is first of all leaking, and there is 10%-20% flow pulsation. Secondly, and more unfortunately, the leakage of the pump is related to the pressure and is non-linear.

How big is the pump and motor for 20 tons of hydraulic cylinder?
According to the working pressure of 25 mpa estimate, the cylinder should use 100mm bore, 63mm piston rod, stroke 40mm. According to 30 reciprocating calculation, the flow rate is about 25 liters/minute. The motor power is 11 kW, want to be cheap, use 25SCY14-1B oil pump can be.
