1. Frequent grease, the electric oil drum pump is running at high speed, and the grease is easy to volatilize, so it is necessary to keep the lubrication at the bearing clean and pay attention to the replacement. 2. Pay attention to the storage of the electric pumping pump should be placed in a dry, clean and no corrosive gas environment. 3. Gear oil ...

1. The hydraulic oil pump cannot absorb oil or have no pressure. Causes 1. The rotation direction of the prime mover and the oil pump is inconsistent. Cleaning method: correct the rotation direction of the prime mover. 2. The oil pump transmission key falls off. Elimination: De novo transmission key. ...

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 ...

The first step is the debugging of the zero position in the no-load state Most of the servo valves on construction machinery are used in conjunction with the reversing valve to achieve the purpose of controlling the hydraulic system. The servo valve plug-in can be unplugged on the site to prevent the servo valve from being energized and make it in a no-load state. Then, a manual or electric directional valve, ...

Progressive optimization of software functions for off-highway equipment requires large-scale remote device updates: The new version of BODAS Connect will provide a solution for this (Image source: Bosch Rexroth AG) 　　Bosch Rexroth will present a solution for remote updates of off-highway equipment at bauma 2022 ...

In modern construction machinery, basically inseparable from hydraulic working devices, even if the main working devices do not use hydraulic equipment, usually need hydraulic systems to achieve some auxiliary work, hydraulic pressure is so important, and our life and work is very close. Image But...

From smartphones to electric vehicles, the need for compact, reliable, and durable batteries is driving many battery manufacturers to ramp up production capacity quickly. But these highly automated battery assembly lines often take months to develop. So, can the speed be accelerated? 　　DWFritz Automa ...

How Rexroth hydraulic pumps are adjusted 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 ...

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 position of the four "flow and pressure limit control" potentiometers on the CPU unit of the computer. 2. The preset parameters adjust the four-stage injection speed to 50 and the pillow pressure to 00 3. Start the oil pump motor, and when the temperature of the sol barrel reaches the sol temperature, press the manual injection button to make the screw ...

Rexroth solenoid valves consist of solenoid coils and magnetic cores, which are valve bodies with one or more holes. When the coil is energized or de-energized, the operation of the core causes the fluid to pass through the valve body or be cut off, changing the direction of the fluid. Electromagnetic components are composed of fixed cores, moving cores, coils and other components; ...

1. The output flow of the hydraulic pump is insufficient or does not output oil Piston pumps often suffer from insufficient suction, excessive leakage, or too small an inclination angle. The insufficient suction volume is mainly caused by the high resistance of the suction pipe or the insufficient oil replenishment, such as the pump speed is too fast and the oil level is too low; Excessive leakage ...

1. Pressure reducing and stabilizing valve Main features: 1. Piston type with DN65 caliber or above. The life of the diaphragm is increased by more than 3 times; 2. Below DN50 caliber, the original diaphragm is replaced by a flat diaphragm of nylon reinforced rubber, which also improves the service life by more than 3 times. Applicable medium: water, air. Medium temperature ...

Rexroth hydraulic pump is mainly divided into three types: piston pump, gear pump and vane pump, among which Rexroth vane pump is a special clamp clamping pump body and pump cover, and the outlet direction of the pump can be in any direction of 360 degrees, which is easy to install and use. The bearing assembly of the sand pump is made of cylindrical structure, ...

1. Causes of noise and vibration failure of relief valves The components that are prone to noise in hydraulic devices are generally considered to be pumps and valves, and the valves are mainly relief valves and electromagnetic reversing valves. There are many factors that contribute to noise. There are two types of noise in the relief valve: velocity sound and mechanical sound. The main ...

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 ...

Rexroth hydraulic pumps have a wide variety of applications and are available in all walks of life. In terms of pump performance, there are two types of pumps: giant pumps and micro pumps. Giant pumps can reach flow rates of hundreds of thousands of cubic meters per hour, while micro pumps can reach less than tens of milliliters per hour. Judging by the pressure of the pump, it can be ...

Technical Parameters: 1) Select the valve port and model according to the requirements of the medium flow direction and the pipeline connection mode; 2) According to the flow rate and valve Kv value to select the nominal diameter, can also choose the same pipe inner diameter; 3) Working Differential Pressure: Low working differential pressure above 0.04Mpa is optional.
