Rexroth A6V series hydraulic motors are available in several variant forms

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. 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: 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. 2: Check the fatigue of all individual parts of the proportional valve, grinding ...

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) 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. 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.

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 ...

1) Swash plate axial piston variable pump, used for open hydraulic rotation back 2) Mainly used in the field of mobile machinery 3) The pump works under the condition of self-priming, mailbox pressurization or with built-in suction pump, (centrifugal pump). 4) The output flow rate is proportional to the driving speed, and ...

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. Close the gate valve before the pressure reducing valve, open the gate valve after the pressure reducing valve, and create a downstream low-pressure environment; 2. Rotate the adjusting screw counterclockwise to the upper position (relative to the low outlet pressure), and then close the gate valve after the pressure reducing valve; 3. Slowly open the gate valve in front of the pressure reducing valve ...

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 ...

Bosch Rexroth Co., Ltd. ("Bosch Rexroth") and Wuxi Weifu High-Tech Group Co., Ltd. ("Weifu Group"), located in Wuxi, Jiangsu Province, China, plan to cooperate to establish a joint venture that aims to combine the strengths of both companies and create a joint venture for ...

Power condition 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% AC, and the power supply voltage fluctuation is usually +%10%.-15%.

1. Large inclination components: all specifications have the same 40 degree inclination angle, high power, small size, high efficiency and economical structure. 2. Monolithic conical plunger with two sealing rings 3. The bearing structure is easy to install and maintain, and has a long service life. 4. Specially improved series of ...

The working principle of Rexroth vane pump PV7 series: Rexroth vane pump PV7 series is a pump in which the blades in the rotor groove are in contact with the pump casing (stator ring) to press the suction liquid from the oil inlet side to the oil discharge side. Because there are two kinds of vane pumps in history, according to the different types of pumps, a) specifically refers to the positive displacement pump ...

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, plug ...

1. Characteristics of the medium 1) Different varieties of solenoid valves are selected for gas, liquid or mixed state; 2) The medium temperature is different for products of different specifications, otherwise the coil will burn off, the seal will age, and the life of the product will be seriously affected; 3) The viscosity of the medium, usually below 50cSt. If...

1. Direct-acting relief valve How it works: The hydraulic force and the spring force are directly balanced to control the opening and closing action of the valve core, so as to ensure that the pressure of the oil inlet is basically constant. Peculiarity: (1) The hydraulic pressure of the valve core is balanced by the spring force, so when the system pressure is very high...
