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 flow rate of Rexroth Rexroth oil pump is the product of the gear pump displacement V per revolution and the speed n, if the speed n of the hydraulic pump is too low, the initial force Q will be too small, can not guarantee the oil supply of the system, resulting in the centripetal force is not enough or can not constitute a certain vacuum degree and can not absorb oil. ...

1) Remove the protective covers on both sides of the flange end, and rinse and clean the valve when the valve is fully open. 2) Before the installation of the balance valve with actuator, the whole machine should be tested according to the specified signal (electricity or gas) (to prevent the vibration caused by transportation from affecting the performance).

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#.

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%.

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 ...

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 ...

A Rexroth hydraulic motor is an actuator of a hydraulic system that converts the liquid pressure energy provided by a hydraulic pump into the mechanical energy (torque and speed) of its output shaft. Hydraulic motors, also known as oil motors, are mainly used in injection molding machinery, ships, hoists, construction machinery, construction machinery, etc.

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, ...

Causes of failure: (1) The oil level of the hydraulic oil tank is too low; Exclusion method: Add hydraulic oil Causes of failure: (2) Hydraulic oil is not used according to the season; Exclusion method: Usually suitable for 46# hydraulic oil (or 68#) without special replacement, consider using 32 ...

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.

The hydraulic motor is fixedly connected to the housing, and the oil propulsion rotor entering from the port rotates around a central point. This slow-rotating rotor drives the output through a splined shaft called a cycloidal hydraulic motor. After the advent of this early cycloid motor, through decades of evolution, another concept of horse ...

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 ...

Working characteristics of Rexroth hydraulic motors 1. Under normal working conditions, the inlet and outlet pressures of the hydraulic motor are higher than the atmospheric pressure, so there will be no suction performance problems like the hydraulic pump. However, if the hydraulic motor can work under the conditions of the pump, its oil inlet should be low.

A10VO series variable piston pump is one of Rexroth variable piston pumps, A10VO series is Rexroth medium pressure series swash plate axial piston pump, nominal pressure 280bar, used in open hydraulic circuits, the pump is very widely used, is used in various fields, including but not limited to...

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 ...

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 ...

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.
