How to choose Rexroth guide rails?

1. Determine the pressure The rated pressure of the selected metering pump is slightly higher than the actual maximum pressure required, generally 10-20% higher. Don't choose too high, too much pressure will waste energy, increase the investment and operating costs of the equipment. 2. Determine the flow rate Selected ...

1) The maximum and minimum temperature of the environment should be selected within the allowable range; 2) When the relative humidity in the environment is high and there are water droplets and rain, waterproof solenoid valves should be selected; 3) Special varieties should be selected for occasions such as vibration, bumps and shocks in the environment, such as marine solenoid valves; ...

1. Trapped oil (1) Causes The trapped oil of the gear pump is caused by the overlap coefficient of the gear design, as shown in the figure below, assuming that the length of the meshing line of the gear in the actual meshing is l and the tooth pitch is t0, then the overlap coefficient of the gear meshing is ε=l/t0. This overlap coefficient has such a ...

The replacement specification of oil lift piston pump parts, when the various clearances listed are out of tolerance, can be corrected as follows: 1) If the cylinder body is inlaid with copper sleeve, it can be corrected by replacing the copper sleeve. First trim a set of plunger rods to a consistent size, and then polish the outer part with sandpaper of more than 1000#.

1. The flow direction of the medium should be consistent with the direction of the arrow of the valve body; 2. The differential pressure balance valve should be installed on the return pipe, the valve is connected to the guide pipe, and the other end of the pressure guide pipe is connected with the water supply pipe, and it is recommended to install a 1/2" ball valve at the water supply end of the pressure guide pipe in order to start the function of eliminating blockage; 3、 ...

1. Classification of piston pumps Piston pumps are generally divided into single piston pumps, horizontal piston pumps, axial piston pumps and radial piston pumps 1. Single piston pump It is mainly composed of an eccentric wheel, a plunger, a spring, a cylinder block and two check valves. A closed volume is formed between the plunger and the cylinder bore. Slanting...

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) 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 and block the B...

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 ...

1. Closed-loop hydrostatic drive swash plate axial piston variable pump; 2. The flow rate is proportional to the driving speed and displacement, and can be a stepless variable; 3. With the change of the swing angle of the swash plate, the flow rate increases from 0 to the maximum; 4. The swash plate swings in the middle position, which can be ...

1. First of all, adjust the pressure adjustment screw of Rexroth variable hydraulic pump relief valve to the loosest state, adjust the minimum flow limiter to the minimum state (the upper hydraulic cylinder adjusting screw is adjusted to the loosest state), adjust the flow control valve adjusting screw to the tightest state, and connect a flow rate in series after the relief valve.

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. 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...

(1) Make sure that the hydraulic oil of Rexroth hydraulic pump is clean and prevent debris from entering the oil. Clean the tank thoroughly when changing the oil and filter it when refueling. (2) Do not paint the inner wall of the oil tank to prevent precipitation in the oil. (3) In order to prevent air from entering the hydraulic system, the oil return nozzle should be lower than the tank fluid.
