(Mexico stern plate hydraulic cylinder,produced by Hengyu Group）

stern plate hydraulic cylinder are widely used in Mexico，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed stern plate hydraulic cylinder for customers from Mexico.

Introduction to stern plate hydraulic cylinder:

If air enters the hydraulic system, the stern plate hydraulic cylinder will not operate normally, mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced.

Most of the failure of the stern plate hydraulic cylinder is because there is a foreign body in the stern plate hydraulic cylinder into the failure of the stern plate hydraulic cylinder, the most problematic is that it is difficult to determine when the foreign body is into the stern plate hydraulic cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

The piston rod of the stern plate hydraulic cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

stern plate hydraulic cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

Answers to some questions about stern plate hydraulic cylinder:

How to disassemble the cylinder?
Generally speaking, it is not difficult to disassemble the hydraulic cylinder, as long as you are careful, but you often encounter some small trouble in the disassembly process, because the disassembly process is not correct. In fact, this can be avoided, as long as you follow below points. 1. Before removing the hydraulic cylinder, the hydraulic circuit should be relieved of pressure, otherwise, when the oil pipe connected with the cylinder is loosened, the high-pressure oil in the circuit will be rapidly ejected. When the hydraulic pressure comes back, the handwheel or pressure regulating screw at the relief valve should be loosened first, so that the pressure oil is unloaded, and then the power supply or power source is cut off, so that the hydraulic device stops running. 2. Disassembly should prevent damage to the top thread of the piston rod, the oil thread and the chrome layer on the piston rod surface.

Why are two cylinders not balanced with the balance valve?
Balancing valve is only suitable for occasions with low synchronous accuracy requirements, and proportional valves are recommended for occasions with high precision requirements.
