Rexroth inverter fault handling and maintenance methods

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 ...

1) Cannot be opened or closed normally 1. Check the power supply and make sure the voltage and frequency are correct. Also check the connection. 2. Check whether there is dirt, corrosion underneath, and the coil will not burn out or lose components. 3. Check whether the flow direction is related to the indicator on the valve body or with the valve ...

1. Workload cycle 2. Oil type 3. Minimum flow rate and maximum flow 4. Pressure range 5. System type: open system or closed system 6. Ambient temperature, system working temperature and cooling system 7. Oil pump type: gear pump, ...

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

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).

First, the characteristics of the solenoid valve: 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 copper alloy as the solenoid valve housing material, otherwise, there are often rust chips falling off in the valve housing, especially the action is infrequent ...

From long-lasting individual components to intelligent mechatronic components: Bosch Rexroth is pushing linear applications forward in a wide range of markets with a wide range of high-quality products. Our new product developments focus on reliability, cost-effectiveness and sustainability. For a long time, the market has been tending to ...

A Rexroth hydraulic motor is an actuator of a hydraulic system that converts the liquid pressure energy provided by a hydraulic pump into the mechanical energy (torque and speed) of its output shaft. Hydraulic motors, also known as oil motors, are mainly used in injection molding machinery, ships, hoists, construction machinery, construction machinery, etc.

Rexroth solenoid valves are composed of solenoid coils and magnetic cores, and are valve bodies containing one or several holes. When the coil is energized or de-energized, the operation of the core will cause the fluid to pass through the valve body or be cut off to change the direction of the fluid. The solenoid parts of the solenoid valve are composed of a fixed core, a moving core...

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 ...

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...

1. It plays the role of pressure stabilization and overflow (the valve port is normally open) In the fixed pump oil inlet or return oil throttling speed control system 2. Safety protection function (valve port normally closed) Variable pump hydraulic system, fixed pump bypass throttling speed regulation system and non-throttling speed regulation system. 3. The effect of anti-load 4、 ...

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.

The expanded Bosch Rexroth Cartesian coordinate system subsystem opens up new areas of application Predefined linear robots are suitable for a wide range of work areas and load ranges ctrlX AUTOMATION is used as a shared automation platform Optional pre-installed software for faster commissioning and programming ...

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 ...

(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. Select the solenoid valve according to the pipeline parameters: the diameter specification (i.e., DN) and the interface mode 1) determine the diameter (DN) size according to the on-site pipeline inner diameter size or flow requirements; 2) Interface mode, generally > DN50 to choose the flange interface, ≤ DN50 can be freely selected according to the user's needs. ...

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. 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 ...

1. There are two oil inlets and one oil return port for the pressure reducing valve and one-way pressure reduction connected by threads and flanges, and one oil inlet and one oil return port for one-way pressure reduction and one-way pressure reduction connected by plate connection. During installation, attention must be paid to connect the oil drain port directly back to the Rexroth hydraulic pump oil tank, and keep the oil drain circuit unblocked.
