The Philippines hydraulic cylinder,stroke adjustable cylinder manufacturer,stroke adjustable cylinder

(The Philippines stroke adjustable cylinder,produced by Hebei Hengyu company）

stroke adjustable cylinder are widely used in The Philippines，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed stroke adjustable cylinder for customers from The Philippines.

Introduction to stroke adjustable cylinder:

We can not just consider the price and ignore the quality when we purchase the stroke adjustable cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the stroke adjustable cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the stroke adjustable cylinder is not required.

The piston rod of the stroke adjustable 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.

Before purchasing the stroke adjustable cylinder, it is necessary to master the original information and design basis, mainly including: the use and working conditions of the machine; The structural characteristics, load conditions, stroke size and operation requirements of the working mechanism; The selected working pressure and flow of the hydraulic system; The reality of materials, fittings and processes; Relevant national standards and technical specifications, etc.

stroke adjustable cylinders in series, parallel and series parallel. Series: In the stroke adjustable cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the stroke adjustable cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the stroke adjustable cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the stroke adjustable cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.

Answers to some questions about stroke adjustable cylinder:

Injection molding machine die thimble on the side of the feed nozzle, the oil cylinder pull the thimble shift, how to debug the oil cylinder?
The cylinder is connected with the neutron of the injection molding machine, the neutron is retreated after the opening mold is in place, the cylinder taps the thimble plate to the top, and then takes, and the neutron is reset.

Why does the hydraulic cylinder not return?
For a spring return cylinder, it is possible that 1, the spring is damaged. You can check it for processing. 2, the oil in the oil path is not unloaded, causing it to be unable to reset. 3, the cylinder piston is dead, resulting in no position. For double-acting cylinders, it is possible to: 1, the spool is not reversed, or is not changed to the correct position, check whether the reversing valve is normal (and whether there is electricity). 2, the cylinder piston is dead, resulting in no position, check and treatment can be. 3, the return oil pressure is insufficient, the inlet oil is not unloaded, the operation is not smooth.
