Common Causes and Troubleshooting Methods of Hydraulic Pumps(9-16)

Piston pumps are generally divided into single piston pumps, horizontal piston pumps, axial piston pumps and radial piston pumps. Single piston pump The structure consists of an eccentric wheel, a plunger, a spring, a cylinder block, and two check valves. A closed volume is formed between the plunger and the cylinder bore. The eccentric wheel rotates and the column ...

The flow rate of Rexroth Rexroth oil pump is the product of the gear pump displacement V per revolution and the speed n, if the speed n of the hydraulic pump is too low, the initial force Q will be too small, can not guarantee the oil supply of the system, resulting in the centripetal force is not enough or can not constitute a certain vacuum degree and can not absorb oil. ...

(1) The pump does not produce oil First of all, check whether the rotation direction of the gear pump is correct; Secondly, check whether the filter at the inlet end of the gear pump is clogged. (2) The oil seal is flushed out (1) The gear pump bearing is subjected to axial force; (2) The gear pump is subjected to excessive radial force. ...

The combination of Bosch Rexroth and Hydfoss contributes to the expansion of the hydraulic portfolio worldwide Join forces to open up new market opportunities and expand sales channels Bosch Rexroth AG (hereinafter referred to as "Bosch Rexroth") plans to acquire a company located in Iraq, United States.

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.

1. Guiding ideology: 1. The pressure depends on the load oil pump, and the output pressure is inversely proportional to the flow rate. In the state of electronic control, when the external load increases, the system pressure increases, when the system pressure increases, the pressure of the front pump oil flow and the rear pump oil flow into the rear pump increases, and the computer detects the ...

Automation experts work together to drive openness WAGO's own devices are equipped with the ctrlX OS Bosch Rexroth and WAGO are working together to develop new industry solutions As soon as the Bosch Rexroth operating system ctrlX OS was launched, it was on the market ...

1) Flow regulation Port X is connected to the oil tank to relieve pressure, and port B is closed, and the pressure reaches the required pressure by rotating the adjusting screw on the FR of the flow control valve, and the general FR setting value is between 14 Bar and 22 Bar 2) Highest pressure regulation Close the flow control valve FR and block the B...

Rexroth hydraulic pump is the power component of the hydraulic system, it refers to the oil pump in the hydraulic system, it is the hydraulic component that provides liquid for hydraulic transmission, and it is also a kind of pump. Its function is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, that is, the hydraulic system is ...

On March 10, 2018, Guangzhou-Yichang City, Hubei Province, located in central China, is a famous city with a long history. Yichang was built on the Yangtze River. For thousands of years, the Yangtze River has stretched down from this vast and fertile land, giving birth to a colorful Jingchu culture. After entering the modern era, the Three Gorges Dam ...

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) Remove the burrs from each part. The sharp edge of the gear is poured with natural oil stone, but not into a fillet. The parts after flat grinding should be demagnetized, and all parts should be carefully cleaned with kerosene before they can be put into assembly. (2) Measure and ensure the axial clearance during assembly: Rexroth gear oil pump axial ...

Classification and structural characteristics of Rexroth gear pumps 　　According to the form of gear meshing, it can be divided into external meshing and internal meshing. According to the different tooth curves, it can be divided into: involute and cycloid. According to the surface form, it can be divided into spur gear type, helical gear type, herringbone gear ...

The automotive industry expects more support from suppliers in quality assurance for assembly work. As a result, suppliers in the automotive industry are looking to automation partners to better meet this technology demand while delivering faster. Mechanical engineering companies need more applications in standard tasks ...

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. ...

When Rexroth hydraulic pump motor has air, how do we correctly eliminate it so that the pump is not damaged, and then share with you the correct exhaust method: (1) The oil has a certain compressibility, resulting in noise, vibration and crawling of moving parts in the system.

1. Poor assembly of Rexroth hydraulic pump leads to abnormal heating of the hydraulic pump 1. The courtyard of Litule hydraulic pump is not suitable, (for example, the plunger and cylinder, blade and rotor groove, sperm and rotor, gear, side plate, etc. are too small, and the sliding part may be overheated.) 2. The installation of Rexroth hydraulic pump ...
