Burma hydraulic cylinder,reciprocating cylinder manufacturer,reciprocating cylinder

(Burma reciprocating cylinder,produced by Hengyu Hydraulic Co., Ltd）

reciprocating cylinder are widely used in Burma，because of no need for deceleration device，long service life，smooth movement.So our company has designed reciprocating cylinder for customers from Burma.

Introduction to reciprocating cylinder:

When the reciprocating cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.

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

reciprocating cylinder piston rod material selection and requirements: ① piston rod is usually made of 45 steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. The piston rod is generally designed as a reciprocating cylinder, if the diameter is larger, the hollow piston rod can be used. Made of No. 45 seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the working surface of the rod can be plated with hard chromium. ⑥ The piston rod and the end cap are guided by H8 ' reciprocating cylinder piston rod industry standard: piston rod diameter series of national recommended standard GB/T2348-1993. Piston rod thread size series standard GB/T2350-1980. Please refer to execute. There is no industry standard for piston rods Both the reciprocating cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The reciprocating cylinder mainly outputs linear motion and force. The reciprocating cylinder has a variety of forms, according to the different characteristics of its mechanism it can be divided into piston type, plunger type and swing type three categories, according to the mode of action he can be divided into single action and double action. Piston reciprocating cylinder, plunger reciprocating cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger reciprocating cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular reciprocating cylinder action. Troubleshooting method: Replace the rubber hose.

Answers to some questions about reciprocating cylinder:

What is the HS code of the hydraulic cylinder?
HS code of hydraulic cylinder; 8412210000 8412210000 Linear hydraulic power unit (hydraulic cylinder) 0.12000 0.35000 0.00000 0.17000 0.00000

Why does the hydraulic cylinder ring?
1 Air intrusion into the hydraulic system is the main reason for noise 2 The relief valve is unstable, such as due to the improper combination of the slide valve and the valve hole or the contact of the cone valve and the seat is stuck by dirt, the damping hole is blocked, the spring is crooked or fails to make the spool stuck or move in the valve hole, causing system pressure fluctuation and noise. 3 Improper adjustment of the reversing valve causes the spool of the reversing valve to move too fast, resulting in reversing impact, resulting in noise and vibration. 4 Mechanical vibration, such as long tubing, elbow more and not fixed, when the oil flow through, especially when the flow rate is high, easy to cause pipe shaking; The rotating part of the motor and hydraulic pump is unbalanced, or the alignment is not good during installation, or the coupling is loose, etc., which can produce vibration and noise.
