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 ...

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 pressure difference: The minimum working pressure difference is above 0.04Mpa.

Rexroth oil pump is a hydraulic system that converts the mechanical energy of the prime mover (motor, internal combustion engine, etc.) into liquid pressure energy. 　　Rexroth oil pumps can be divided into two types: positive displacement and non-volumetric type. The non-volumetric type has centrifugal pumps, axial flow pumps, etc., and uses high-speed rotating impellers to produce true ...

1) Swash plate axial piston variable pump for open hydraulic rotation circuit 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, ...

The balancing principle of the balancing valve and its function are explained The principle of balance The TA balancing concept is the concept of total equilibrium, which believes that only after the resistance of the system is adjusted and balanced, can each equipment obtain the design flow under the design operating conditions. Fluid network system for the HVAC industry ...

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 ...

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.

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 ...

Power outage handling If the power supply is instantaneously blacked out or the voltage drops to show "undervoltage", or the instantaneous overvoltage shows "overvoltage", it will cause the Rexroth inverter to trip and shut down, and it will be restarted only after the power supply returns to normal. External fault handling If you enter ...

1. Rexroth hydraulic piston pump A10VsO series: A10VsO18, A10VsO28, A10VsO45, A10VsO71, A10VsO100, A10VsO140 2. Rexroth hydraulic piston pump A10VO series: A10VO28, A10VO45, A10VO71, A10VO100, A10VO140 3 ...

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 ...

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, ...

In general, there are two ways to adjust it 1. Add a speed regulating valve at the outlet of the pump to adjust the output speed of the oil volume, so as to achieve the amount of oil used 2. Add a variable pump with oil volume, adjust the angle of the oil pan to achieve the input quantity of changing the oil volume. This method compares ...

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 ...

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 ...

One. Wrong installation method: 1. The coupling is too tight: Because the coupling and shaft fit clearance is too small or no backlash, the bearing will be damaged when struck hard, resulting in early bearing damage and affecting the life of the entire pump core. 2. Axial force on the shaft head: Because...
