Basic understanding of Rexroth solenoid valves

The replacement specification of oil lift piston pump parts, when the various clearances listed are out of tolerance, can be corrected as follows: 1) If the cylinder body is inlaid with copper sleeve, it can be corrected by replacing the copper sleeve. First trim a set of plunger rods to a consistent size, and then polish the outer part with sandpaper of more than 1000#.

For example, it was the first injection molding machine to open ...

Causes of failure: (1) The oil level of the hydraulic oil tank is too low; Exclusion method: Add hydraulic oil Causes of failure: (2) Hydraulic oil is not used according to the season; Exclusion method: Usually suitable for 46# hydraulic oil (or 68#) without special replacement, consider using 32 ...

1. Trapped oil (1) Causes The trapped oil of the gear pump is caused by the overlap coefficient of the gear design, as shown in the figure below, assuming that the length of the meshing line of the gear in the actual meshing is l and the tooth pitch is t0, then the overlap coefficient of the gear meshing is ε=l/t0. This overlap coefficient has such a ...

On November 11, 2020, the opening ceremony of the second phase of Bosch Rexroth (Xi'an) Electronic Drive and Control Co., Ltd. was grandly held. With the completion of the second phase of the project, the Xi'an plant will become the overall supplier of the group's global intelligent manufacturing and industrial automation solutions, and Bosch Rexroth will provide the best solutions for the Chinese market.

1. According to the layout of the device, terrain conditions, water level conditions, and operating conditions, determine the selection of horizontal, vertical and other types (pipeline, submersible, submersible, non-clogging, self-priming, gear, etc.) gear pumps. 2. According to the nature of the liquid medium, determine the water gear ...

From long-lasting individual components to intelligent mechatronic components: Bosch Rexroth is pushing linear applications forward in a wide range of markets with a wide range of high-quality products. Our new product developments focus on reliability, cost-effectiveness and sustainability. For a long time, the market has been tending to ...

Thanks to the die pad function of the new standard IH04 E standard module from Bosch Rexroth, engineers can use the most common switching systems. These modules are DGUV-tested and certified with a standardized safety concept and are able to meet general safety requirements at the lowest possible cost. Users can optionally set such ...

1. Rexroth relief valve Overflow, pressure stabilizer, which is used to regulate and maintain the oil supply pressure of the pump while overflowing the excess oil in the system. When the regulated pressure is reached, the hydraulic system is controlled to keep it in a constant state. Relief valves for overload protection are called safety valves. ...

1. It plays the role of pressure stabilization and overflow (the valve port is normally open) In the fixed pump oil inlet or return oil throttling speed control system 2. Safety protection function (valve port normally closed) Variable pump hydraulic system, fixed pump bypass throttling speed regulation system and non-throttling speed regulation system. 3. The effect of anti-load 4、 ...

1. When installing, the tap water pressure reducing valve should be installed vertically on the tap water pipeline. 2. The arrow on the tap water pressure reducing valve must be consistent with the arrow on the pipeline. 3. The position of the installation of the pressure reduction method must be greater than 4 meters from the valve outlet. ...

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 filter on the suction pipeline is blocked; 2. The oil level of the hydraulic oil tank is too low; 3. The R angle of the variable mechanism is too small, so that the flow rate is too small, and the influence of internal leakage is added, so it cannot continuously supply pressure oil to the outside world; 4. The strain between the oil distribution pan and the contact surface of the cylinder block is serious, and it is not sealed or ...

1. Adopt the correct Rexroth vane pump speed conversion method, the conversion mode of the solenoid valve, the impact is larger, the conversion accuracy is lower, the reliability is poor, but the control flexibility is large; 2. The electro-hydraulic reversing valve uses a current valve with damping, and by adjusting the damping size, the Rexroth blades ...

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...)

On March 4th, as a well-known intelligent packaging exhibition in Asia, China International Packaging Industry Exhibition Guangzhou was grandly opened. As the world's leading supplier of complete automation systems, Bosch Rexroth offers a high level of automation and electrical control and linear drive technology.

1) If the cylinder body is inlaid with copper sleeve, it can be repaired by replacing the copper sleeve. First of all, trim the diameter of a set of plunger rods to a uniform size, and then polish the outer diameter with sandpaper of more than 1000#. There are three ways to install copper sleeves in the cylinder block: (a) Heating and hot charging of the cylinder block or low-temperature freezing and extrusion of the copper sleeve, interference ...

1. Maintain a proper oil temperature The working temperature of the hydraulic system is generally controlled between 30 and 80 °C (dangerous temperature ≥ 100 °C). Too high oil temperature in the hydraulic system will lead to: the viscosity of the oil will decrease, which will easily cause leakage and reduce efficiency; The strength of the lubricating oil film decreases, accelerating the mechanical ...
