Luxembourg hydraulic cylinder,rack cylinder manufacturer,rack cylinder

(Luxembourg rack cylinder,produced by Hengyu Hydraulic Co., Ltd）

rack cylinder are widely used in Luxembourg，because of no need for deceleration device，excellent temperature resistance，no transmission clearance.So our company has designed rack cylinder for customers from Luxembourg.

Introduction to rack cylinder:

The definition of the minimum starting pressure of the rack cylinder refers to the minimum working pressure of the rack cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the rack cylinder parts and the size of the sealing friction.

1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.

The main role of the rack cylinder: the rack cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the rack cylinder realizes reciprocating motion. The structure of the rack cylinder has three categories: piston rack cylinder, plunger rack cylinder, swing rack cylinder, piston rack cylinder and plunger rack cylinder to achieve reciprocating linear motion, output speed and thrust, swing rack cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the rack cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The rack cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

rack 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 rack 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 ' rack 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 rack cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The rack cylinder mainly outputs linear motion and force. The rack 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 rack cylinder, plunger rack cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger rack cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

Answers to some questions about rack cylinder:

Hydraulic cylinder cost calculation method
1, Price cost accounting. Hydraulic cylinder price is composed of cost, profit and tax rate. Among them, the cost includes material cost, processing cost, assembly test fee, factory management fee (including the cost of designing drawings, etc., and the salary of management personnel is shared equally), brand promotion fee, utility and electricity equipment depreciation fee and other expenses. Cost of materials, including cylinder composition cylinder, piston rod, front and rear cover, guide, piston, seal, other accessories, etc. 2, Roughly estimate cylinder price = cylinder weight * parameters, parameters comprehensive consideration of various material costs and processing fees. The general market parameter is 20, the smaller and lighter the cylinder, the larger and heavier the cylinder, the smaller the parameter.

How to calculate the hydraulic cylinder pressure, how much pressure can put up how much weight?
There is a formula for air pressure, hydraulic pressure, water pressure: F=P×S type: f-cylinder or hydraulic cylinder output, unit is Newton (N) P- pressure, unit is Mpa S- effective area, unit is square millimeter (mm2), note: is the effective area, in the hydraulic cylinder to subtract the cross-sectional area of the piston rod.
