Long lifespan 4. Variables are convenient and have many forms 5. Light weight per unit power 6. Force ...

The emergence of "ready-to-shelf cartons" has changed the situation by bringing retailers and consumers closer together with the new carton that combines fast shelf and display. After the goods are delivered to the supermarket, the staff only needs to open the closed boxes on all sides, and the cartons are "immediately" into pallets.

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.

Simplify the design The complete solution can be customized according to the user's needs Digital on-board electronics Compact design (integrated pressure sensor technology) External pressure sensor connection to meet the user's customized application needs The interface can be customized on demand ...

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.

1. For easy operation and maintenance, the valve is generally installed upright on the horizontal pipeline. 2. The installation of Rexroth pressure reducing valve DR6 must be in strict accordance with the direction of the arrow on the valve body to keep consistent with the direction of fluid flow. If the water quality is not clean and contains some impurities, it must be decompressed at Rexroth ...

1) Rexroth vane pumps: Some users do not fill the pump with enough water before starting; It appears that the water has spilled out of the vent, but the air is completely discharged without turning the pump shaft, so that a little air remains in the inlet pipe or pump body. 2) Rexroth vane pump contact inlet pipe horizontal section of the counter-water flow ...

1. Direct-acting solenoid valve Principle: When the normally closed type is energized, the electromagnetic coil generates electromagnetic force to lift the open part from the valve seat and open the valve; When the power is off, the electromagnetic force disappears, the spring presses the opening on the valve seat, and the valve is open. Features: In vacuum, negative pressure, zero pressure ...

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 ...

The classification of proportional valve control mode refers to the classification of the electrical-mechanical conversion mode in the pilot control valve of the proportional valve, and its electrical control part has various forms such as proportional solenoids, torque motors, DC servo motors, etc. (1) Electromagnetic type Electromagnetic type refers to the use of proportional electromagnets.

1. Check whether the piston pump is damaged and corroded, and replace it if so. 2. Check the fit of the plunger pair. Insert the end of the plunger into the plunger sleeve, tilt it about 60°, and if the plunger can slide slowly under its own action, it will fit well. 3. Check the tightness of the plunger pair. Use...

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.

Space-saving design: The measuring sensor is fully integrated into the slide Cost-effective position measurement system for a wide range of product sizes From design to service, save time and money 　　Integrated absolute position measurement is used in a wide range of applications, due to its high water ...

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 ...

At the Hannover Messe 2023, Bosch Rexroth presented several open, easy-to-integrate automation solutions and will continue to drive the digital transformation of mechanical engineering. In the field of hydraulics, Bosch Rexroth is transferring more functions to the software. The solution adopts the ...

1) According to the type of power supply, AC and DC solenoid valves are selected respectively. In general, AC power is easily accessible; 2) AC220V.DC24V is preferred for voltage specifications; 3) The power supply voltage fluctuation is usually +%10%.-15% for AC, and about ±%10 for DC allowable ...

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. 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. ...

1. Closed-loop hydrostatic drive swash plate axial piston variable pump; 2. The flow rate is proportional to the driving speed and displacement, and can be a stepless variable; 3. With the change of the swing angle of the swash plate, the flow rate increases from 0 to the maximum; 4. The swash plate swings in the middle position, which can be ...

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 ...
