Step 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. Step 2: Check the ...

1. Classification of piston pumps Piston pumps are generally divided into single piston pumps, horizontal piston pumps, axial piston pumps and radial piston pumps 1. Single piston pump It is mainly composed 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. Slanting...

1. The flow direction of the medium should be consistent with the direction of the arrow of the valve body; 2. The differential pressure balance valve should be installed on the return pipe, the valve is connected to the guide pipe, and the other end of the pressure guide pipe is connected with the water supply pipe, and it is recommended to install a 1/2" ball valve at the water supply end of the pressure guide pipe in order to start the function of eliminating blockage; 3、 ...

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) Remove the protective covers on both sides of the flange end, and rinse and clean the valve when the valve is fully open. 2) Before the installation of the balance valve with actuator, the whole machine should be tested according to the specified signal (electricity or gas) (to prevent the vibration caused by transportation from affecting the performance).

1. Hydraulic pump: Straight shaft swash plate piston pumps are divided into two types: pressure oil supply type and self-priming oil type. Most of the pressure oil supply hydraulic pumps use oil tanks with air pressure, and there are also hydraulic pumps with oil replenishment sub-pumps to provide pressure oil to the oil inlet of the hydraulic pump. The self-priming oil energy of the self-priming hydraulic pump ...

1. First, adjust the pressure adjusting screw of the relief valve to the loosest state, adjust the minimum flow limiter to the minimum state (the adjusting screw of the hydraulic cylinder in the upper part is adjusted to the loosest state), adjust the adjusting screw of the flow control valve to the tightest state, and connect a flowmeter in series after the relief valve; 2. Start-up fluid ...

With the combination of sensor systems and six degrees of freedom independent kinematics, the Bosch Rexroth Smart Flex Effector compensation module gives industrial robots a human-like sense of touch, providing automation for processes that were difficult to handle or had to be performed manually in the past.

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 hydraulic pump has no flow rate. In fact, this is broadly similar to the reason why Rexroth hydraulic pumps have no pressure as mentioned earlier. Here can be referred to by the explanation of the past period, and a few points can be added. 1. Installed on Rexroth hydraulic pump ...

1. 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. Before the piston pump is started, the pump must be filled with clean working oil through the oil drain port on the casing. 2. The viscosity of the oil is affected by the temperature ...

The easy-to-set up, highly integrated mechatronic subsystem provides a more efficient engineering handling solution. With the new Cartesian multi-axis system, Bosch Rexroth linear drive technology offers you a valuable competitive advantage. The handling robot, which consists of linear axes, flows through the entire value ...

High efficiency: The efficiency of imported Rexroth hydraulic motor A2FE107/61W-VZL100 can reach more than 90%, which has a higher energy utilization rate than other hydraulic motors, and can significantly improve the work efficiency of mechanical equipment. High reliability: Rexroth hydraulic motors are made of high-strength ...

For the field of profiling cutting, there is a growing demand to increase productivity and shorten set-up times and CNC interpolation time. The Bosch Rexroth MTX CNC system provides the perfect basis for machine builders and users to meet the growing challenges and at the same time comply with the requirements of the OPC UA standard for Industry 4.0 communication ...

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 ...

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. 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. 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. 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 ...
