(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 ...

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. When installing, the tap water pressure reducing valve should be installed vertically on the tap water pipeline. 2. The arrow on the tap water pressure reducing valve must be consistent with the arrow on the pipeline. 3. The position of the installation of the pressure reduction method must be greater than 4 meters from the valve outlet. ...

1. Determine the use of Tiaohua Determine the necessary conditions in order to calculate the loads acting on the linear guide 2. Choose the right type Select the type that meets the criteria and pre-select the possible specifications 3. Calculate the applied load Calculate the ...

1. The power domain (working limit) of the proportional valve For direct-acting electro-hydraulic proportional throttle valves, since the hydraulic force acting on the valve core is proportional to the flow rate and flow rate (pressure) through the valve port, when the working condition of the electro-hydraulic proportional throttle valve exceeds the product of its pressure drop and flow rate, that is, the power meter...

The combination of Bosch Rexroth and Hydfoss contributes to the expansion of the hydraulic portfolio worldwide Join forces to open up new market opportunities and expand sales channels Bosch Rexroth AG (hereinafter referred to as "Bosch Rexroth") plans to acquire a company located in Iraq, United States.

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 ...

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 ...

Example: A10VSO18DFR1/31R-PPA12N00 A10VS→ swash plate variable pump, this series of industrial drive, nominal pressure 28MPa, maximum pressure 35MPa; o → operation mode, this series is used in open circuit systems; 18 → displacement specifications of this model ...

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. Cause of failure: the oil level of the hydraulic oil tank is too low; Exclusion method: Add hydraulic oil. 2. Cause of failure: Hydraulic oil is not used according to the season; Exclusion method: Usually suitable for 46# hydraulic oil (or 68#) without special replacement, consider using it when it is cold in the north in winter...

When Rexroth hydraulic pump motor has air, how do we correctly eliminate it so that the pump is not damaged, and then share with you the correct exhaust method: (1) The oil has a certain compressibility, resulting in noise, vibration and crawling of moving parts in the system.

Hydraulic pumps can be divided into four types according to their working principle, the details are as follows. 1. Gear pump The volume is smaller, the structure is simpler, the cleanliness of the oil is not strict, and the price is cheaper; However, the pump shaft is subject to unbalanced force, severe wear and tear, and large leakage. 
Externally meshing gear pump when tooth ...

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) 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 ...

9. Cause of failure: "left-handed" oil pump is installed with "right-handed", resulting in damage to the skeleton oil seal; Exclusion method: the "right-handed" pump cannot be installed on the "left-handed" machine, otherwise the skeleton oil seal will be damaged; 10. Cause of failure: The hydraulic oil is too dirty. Exclusion Method: Cleaning System, ...

The emergence of "ready-to-shelf cartons" has changed the situation by bringing retailers and consumers closer together with the new carton that combines fast shelf and display. After the goods are delivered to the supermarket, the staff only needs to open the closed boxes on all sides, and the cartons are "immediately" into pallets.

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 ...
