Uganda spring return cylinder

(Uganda spring return cylinder,produced by Hengyu Hydraulic Co., Ltd)

spring return cylinder are widely used in Uganda,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed spring return cylinder for customers from Uganda.

Introduction to spring return cylinder:

If it is found that the spring return cylinder lubrication is poor or the spring return cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the spring return cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the spring return cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the spring return cylinder center line. In this way, when the piston works in the spring return cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the spring return cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

Most of the failure of the spring return cylinder is because there is a foreign body in the spring return cylinder into the failure of the spring return cylinder, the most problematic is that it is difficult to determine when the foreign body is into the spring return 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.

When the spring return cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the spring return cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.

spring return 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 spring return 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.

Answers to some questions about spring return cylinder:

How does the cylinder work?
Hydraulic transmission principle: oil as the working medium, through the change of the sealing volume to transfer movement, through the internal pressure of the oil to transfer power. 1. The power part - converts the mechanical energy of the prime mover into the pressure energy of the oil (hydraulic energy). For example: hydraulic pump. 2, the executive part - the hydraulic pump input oil pressure energy into the mechanical energy to drive the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3, the control part - used to control and adjust the oil pressure, flow and flow direction. For example: pressure control valve, flow control valve and direction control valve. 4, the auxiliary part - the first three parts are connected together to form a system, which plays the role of oil storage, filtration, measurement and sealing.

How to calculate the tonnage of the hydraulic press without konowing the diameter of the cylinder?
To know the tonnage of the hydraulic cylinder, you first need to know the working pressure of the hydraulic system, the inner diameter of the hydraulic cylinder and the outer diameter of the cylinder rod (the outer diameter of the cylinder rod is needed when calculating the hydraulic cylinder tension). The thrust of the hydraulic cylinder (that is, the force that the hydraulic cylinder can produce by extending out) = the cross-sectional area of the hydraulic cylinder (or the cross-sectional area of the piston) × the working pressure of the cylinder (the cross-sectional area of the piston) =pi*D^2/4= PI (take 3.14) × the square of the cross-sectional area of the piston ÷4 working pressure to see the pressure displayed on the pressure gauge when the maximum load is working.
