Rexroth A10VSODFR pressure flow regulation method for piston pumps

Analysis of abnormal heating fault of vane pump: 1. The oil temperature is too high 2. The oil cat degree is too large and the internal leakage is too large 3. The working pressure is too high 4. The oil return port is directly connected to the pump population Abnormal heating elimination method of vane pump: 1. Improve the heat dissipation conditions of the fuel tank or use cooling ...

1. Adjust the displacement of the pump: The larger the displacement of the hydraulic piston pump, the greater the flow and pressure. The displacement can be adjusted by replacing the displacement of the pump or adjusting the eccentricity distance of the pump. 2. Adjust the valves in the hydraulic system: The valves in the hydraulic system can control the flow and pressure.

(1) Make sure that the hydraulic oil of Rexroth hydraulic pump is clean and prevent debris from entering the oil. Clean the tank thoroughly when changing the oil and filter it when refueling. (2) Do not paint the inner wall of the oil tank to prevent precipitation in the oil. (3) In order to prevent air from entering the hydraulic system, the oil return nozzle should be lower than the tank fluid.

1) Piston pumps are generally used in the hydraulic transmission systems of machine tools, metallurgy, forging, mining and hoisting machinery, and are especially widely used in high-power hydraulic transmission systems. 2) REXROTH vane pumps are generally used in mining, coal, metallurgy, chemical industry, environmental protection and other industries. One...

Volumetric efficiency (actual discharge/theoretical discharge) rotates at low speed, and internal leakage increases when used at high pressure, and efficiency decreases. Solid shaft dynamics (theoretical shaft dynamics/mechanical efficiency): number of rotations, increased pressure, increased mechanical efficiency. Real discharge (volumetric efficiency), real axis power and number of rotations ...

First of all, there are no strict regulations and explanations for the difference between Rexroth proportional valves and Rexroth servo valves, which is the main reason why most people do not understand the difference between the two.

The working principle of Rexroth vane pump PV7 series: Rexroth vane pump PV7 series is a pump in which the blades in the rotor groove are in contact with the pump casing (stator ring) to press the suction liquid from the oil inlet side to the oil discharge side. Because there are two kinds of vane pumps in history, according to the different types of pumps, a) specifically refers to the positive displacement pump ...

A10VO series variable piston pump is one of Rexroth variable piston pumps, A10VO series is Rexroth medium pressure series swash plate axial piston pump, nominal pressure 280bar, used in open hydraulic circuits, the pump is very widely used, is used in various fields, including but not limited to...

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...)

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 ...

1. Characteristics of the medium 1) Different varieties of solenoid valves are selected for gas, liquid or mixed state; 2) The medium temperature is different for products of different specifications, otherwise the coil will burn off, the seal will age, and the life of the product will be seriously affected; 3) The viscosity of the medium, usually below 50cSt. If...

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 purpose of using Rexroth Rexroth proportional valve or servo valve is: to achieve throttling control of the flow rate in an electronic control way (of course, pressure control can also be achieved after structural changes), since it is throttling control, there must be energy loss, servo valve is different from other valves, its ...

Rexroth Pressure Reducing Valve Failure Analysis: 1. Air is mixed into the oil 2. The damping hole is sometimes clogged 3. The roundness of the hole between the slide valve and the valve body exceeds the regulations, so that the valve is stuck 4. The spring is deformed or stuck in the spool valve, making it difficult for the spool to move or the spring is too soft 5.

First, the rigidity of the hydraulic oil decreases sharply, resulting in the slower response of the hydraulic system and the reduction of efficiency, resulting in crawling and vibration of the actuator. Second, air bubbles will cause oil film to be unable to form between moving parts, resulting in poor lubrication and aggravating the wear of hydraulic components. The third is in the air ...

First wash. The first cleaning of the hydraulic system of the Rexroth Rexroth hydraulic pump is carried out after the pre-installation (trial assembly of the pipes) and the dismantling of the entire pipeline. The first cleaning should ensure that a large number of metal burrs and powders, sand dust, ...
