What to do when air enters the Rexroth hydraulic pump motor?

At the International Rubber Congress 2022 in Nuremberg, Bosch Rexroth presents a new Heglon drive specially developed for rubber machinery. It is designed to significantly reduce energy consumption and thus CO2 emissions in daily operations. Similar to traditional electromechanical drives, the pre-assembled ...

1. In the mining and metallurgical industry, the pump is also the most used equipment. Mines need to be drained by pumps, and in the process of beneficiation, smelting and rolling, pumps are needed to supply water first. 2. In the power sector, nuclear power plants need nuclear main pumps, secondary pumps, tertiary pumps, thermal power plants need a large number of boilers ...

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 ...

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. Check the internal leakage of the boom cylinder. The easiest way to do this is to raise the boom and see if it has a noticeable free descent. If the drop is obvious, disassemble the cylinder for inspection, and replace the sealing ring if it is worn; 2. Check the control valve. First of all, clean the safety valve and check whether the valve core is grinding.

1. Conduct regular testing and diagnosis of Rexroth piston pumps According to the listening and collecting signals, the western line diagram of the online working performance of the Tule Pillar Jiquan was made, and the evaluation report was made. Based on the results of home monitoring, it is decided whether to repair the Rexroth plunger atmosphere. In this way, the optimal dimension of the Piston Pump ...

peculiarity 1. Rexroth solenoid valve, solenoid valve and all stainless steel; For highly corrosive media, the diaphragm type must be selected. Neutral medium, it is also advisable to choose a solenoid valve with copper alloy as the housing material, otherwise, rust chips often fall off in the valve housing, especially when the action is infrequent. Ammonia valves ...

1. Constant displacement, 2. Low working noise 3. Low flow pulsation 4. Due to the sealing gap compensation, it has high efficiency even at low speed and low viscosity oil 5. It is suitable for a wide range of viscosity and speed 6. All model specifications and displacement gauges ...

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 ...

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

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 ...

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, ...

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 ...

The hydraulic motor is fixedly connected to the housing, and the oil propulsion rotor entering from the port rotates around a central point. This slow-rotating rotor drives the output through a splined shaft called a cycloidal hydraulic motor. After the advent of this early cycloid motor, through decades of evolution, another concept of horse ...

1. The speed and pressure of the pump should not exceed the specified value, and long-term use should be avoided, otherwise the life of the hydraulic pump will be affected. 2. When the hydraulic pump is started, it should be jogged several times, and after the oil flow direction and sound are normal, it should run under low pressure for 5-10min, and then put into normal operation. ...

Rexroth vane pump speed selection Rexroth vane pump flow rate and speed linear relationship, relative to low speed screw pump, high speed screw pump can increase the flow and head, but the power is significantly increased, high speed accelerates the wear between the rotor and the stator, must make the screw ...

· Integrate know-how from all parties through an ecosystem · Low-code/no-code: Five times faster time to market · Independence from global supply chains · Long-term availability The industrial automation transformation is well underway and will take a big step forward in 2022.
