The working characteristics and working principle of Rexroth hydraulic motors

On March 4th, as a well-known intelligent packaging exhibition in Asia, China International Packaging Industry Exhibition Guangzhou was grandly opened. As the world's leading supplier of complete automation systems, Bosch Rexroth offers a high level of automation and electrical control and linear drive technology.

1. According to the form of gear meshing, it can be divided into: external meshing and internal meshing 2. According to the tooth shape curve, it can be divided into: involute tooth form and cycloidal type 3. According to the form of the tooth surface, it can be divided into: spur gear type, helical gear type, herringbone gear type, arc tooth surface gear type 4. Press ...

(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. ...

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...

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 ...

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 ...

1. Check whether the Rexroth vane pump shaft follows the motor rolling: if the motor rolls and the Rexroth vane pump shaft does not rotate, it may be a missing key on the Rexroth vane pump shaft or the key on the motor. 2. Check whether the rotation direction of Rexroth vane pump is correct: the steering is wrong, Rexroth ...

1. First of all, adjust the pressure adjustment screw of the Rexroth variable hydraulic pump relief valve to the loosest state, the minimum flow limiter to the minimum state (the upper hydraulic cylinder adjusting screw is adjusted to the loosest state), the flow control valve adjustment screw is adjusted to the tightest state, and connect a flow rate in series after the flow valve.

1. Preparation before starting: check the fastening of each component; Check the oil level of the oil tank, the height of the oil level is subject to the engraving line of the oil window on the oil tank, N46 in summer, N32 hydraulic oil in winter. High-pressure pumps and pumps above 140 should use the same type of anti-wear hydraulic oil. Check the pressure gauge range, liquid ...

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 ...

1) Electrical proportional mode, to achieve stepless control of outlet pressure. 2) It can realize remote control and program control. 3) Compared with intermittent control, the system is simplified and the components are greatly reduced. 4) Compared with hydraulic proportional valves, it is small in size, light in weight, compact in structure, and lightweight.

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. The pressure of Rexroth piston pump cannot rise: 1. Rexroth piston pump does not have oil or insufficient flow - the same as the above elimination method. 2. The adjustment pressure of the relief valve is too low or faulty - re-adjust the pressure of the relief valve or repair the relief valve. 3. There is a leak in the system.

1. The pump device, composed of a motor and an oil pump, is the power source of hydraulic pressure and the "heart", and its role is to convert mechanical energy into the power of the cylinder to realize the lifting of goods. 2. The combination valve is a flat valve installed on the vertical plate, and its function is to adjust the direction, pressure and flow rate of the hydraulic oil.

1. It is necessary to avoid the retention of dirt and debris into the pressure reducing valve pressure reduction guarantee system. The pipe network of the pressure reduction system of the new or renovated project is likely to leave sand, hemp silk and debris. Before putting into operation, water flushing should generally be carried out, and after meeting the cleaning requirements, the pressure reducing valve and filter element should be finally installed.

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 ...

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 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 ...

During the meshing process of the gear pump, the number of gear pairs meshed at the same time should be more than one pair, that is, the overlap coefficient ε should be greater than 1 (ε=1.4) to work normally. The oil left between the teeth is trapped in an enclosed space formed by two pairs of teeth meshing at the same time, and the volume of this space will be ...

1. Constant pressure overflow: In the throttling adjustment system of the quantitative pump, the fixed pump provides a constant flow rate. 2. When the system pressure increases, the flow demand decreases. 3. At this time, the safety valve is opened, so that the excess flow is returned to the oil tank to ensure the inlet pressure of the safety valve.
