How Rexroth hydraulic pumps are adjusted

1. Quantitative pump + relief valve system This is the most basic and low-cost hydraulic pump system, because the displacement of the pump is fixed, and the output flow is fixed under the condition that the speed of the prime mover is unchanged; A part of the flow drives the load, and the excess flow is returned to the tank through the relief valve, and the overflow ...

1. The power domain (working limit) of the proportional valve For direct-acting electro-hydraulic proportional throttle valves, since the hydraulic force acting on the valve core is proportional to the flow rate and flow rate (pressure) through the valve port, when the working condition of the electro-hydraulic proportional throttle valve exceeds the product of its pressure drop and flow rate, that is, the power meter...

There are 3 precautions when installing a hydraulic pump in the hydraulic system: 1. The coaxiality deviation between the hydraulic pump drive shaft and the motor drive shaft is less than that, and the flexible coupling joint is generally used, and the V-belt is not allowed to directly drive the pump shaft to rotate, and the pump shaft is subjected to excessive radial force, which affects the normal operation of the pump; 2 ...

1) The maximum and minimum temperature of the environment should be selected within the allowable range; 2) When the relative humidity in the environment is high and there are water droplets and rain, waterproof solenoid valves should be selected; 3) Special varieties should be selected for occasions such as vibration, bumps and shocks in the environment, such as marine solenoid valves; ...

The first step is the debugging of the zero position in the no-load state Most of the servo valves on construction machinery are used in conjunction with the reversing valve to achieve the purpose of controlling the hydraulic system. The servo valve plug-in can be unplugged on the site to prevent the servo valve from being energized and make it in a no-load state. Then, a manual or electric directional valve, ...

Progressive optimization of software functions for off-highway equipment requires large-scale remote device updates: The new version of BODAS Connect will provide a solution for this (Image source: Bosch Rexroth AG) 　　Bosch Rexroth will present a solution for remote updates of off-highway equipment at bauma 2022 ...

1: Disassemble the proportional valve Unscrew the nut and slide out of the coil to remove the coil from the proportional end. Use a wrench to loosen and remove the tube. Remove the spring and slide the hex wrench from the tube. Then remove the spool from the valve. 2: Check the fatigue of all individual parts of the proportional valve, grinding ...

1. Cause of failure: the oil level of the hydraulic oil tank is too low; Exclusion method: Add hydraulic oil. 2. Cause of failure: Hydraulic oil is not used according to the season; Exclusion method: Usually suitable for 46# hydraulic oil (or 68#) without special replacement, consider using it when it is cold in the north in winter...

In modern construction machinery, basically inseparable from hydraulic working devices, even if the main working devices do not use hydraulic equipment, usually need hydraulic systems to achieve some auxiliary work, hydraulic pressure is so important, and our life and work is very close. Image But...

The MP1000R developed by Bosch Rexroth in cooperation with Geek+ won the Innovation Award in the Material Handling and Packaging category of the New Equipment Digest (NED). The award is made by NED readers to vote for the finalists based on the product information provided to determine the most innovative product in the category. 　MP1 ...

1. Frequent grease, the electric oil drum pump is running at high speed, and the grease is easy to volatilize, so it is necessary to keep the lubrication at the bearing clean and pay attention to the replacement. 2. Pay attention to the storage of the electric pumping pump should be placed in a dry, clean and no corrosive gas environment. 3. Gear oil ...

Rexroth piston pump failure manifests itself as follows. The causes and elimination methods of excessive working noise of piston pumps. There is air in the oil pump. This failure usually occurs when a new pump is installed. When opening a new pump, oil should be added to the pump first to lubricate the pump's bearings, plungers, and cylinders. ...

There are three main types of hydraulic pumps: gear pumps, vane pumps and piston pumps. 1. Gear pump: Advantages: small size, simple structure, less strict requirements for the cleanliness of the oil, and cheaper price; Defects: However, the pump shaft is subject to unbalanced force, serious wear, and leakage.

1. The bearing of the hydraulic motor can withstand the radial force, and the transmission parts such as the pulley shall not be directly installed on the spindle for the motor that cannot withstand the radial force. The driving sprocket is driven by a hydraulic motor, and the driven sprocket drives the conveyor belt roller. According to the user's report, the motor often leaks...

EW stands for Exchange EG stands for Direct Current The meaning of each letter of Rexroth solenoid valve: For example, 4WE6E6X/EG24N9K4 4→ 4-way (there are also 3-way) 4-way ports 6→ is 6 E→ functional symbols (also C, D, E, EA...)

Less is more: Lean manufacturing is an important competitive factor for manufacturing companies. It's a question of how processes can be optimised so that they can act faster and more flexibly to increase economic efficiency, and the same applies to intralogistics. If the logistics are not properly organized, regardless of the production ...

1. Daily maintenance 1) Strictly implement the post operation method and carefully fill in the operation records. 2) Check the bearing temperature and oil pressure regularly; Check the level height of the lubricating oil every shift. 3) Check whether there is leakage in the sealing part once per shift. 4) Do a good job in each shift ...

Rexroth solenoid valves are composed of solenoid coils and magnetic cores, and are valve bodies containing one or several holes. When the coil is energized or de-energized, the operation of the core will cause the fluid to pass through the valve body or be cut off to change the direction of the fluid. The solenoid parts of the solenoid valve are composed of a fixed core, a moving core...

Technical Parameters: 1) Select the valve port and model according to the requirements of the medium flow direction and the pipeline connection mode; 2) According to the flow rate and valve Kv value to select the nominal diameter, can also choose the same pipe inner diameter; 3) Working Differential Pressure: Low working differential pressure above 0.04Mpa is optional.
