Germany rexroth pump simple introduction
Rexroth booster pump is conveying fluid or fluid mechanical.It transmits the mechanical energy or other external energy transmitted to the liquid, causes the liquid energy increase.
Rexroth pumps are mainly used for conveying water, oil, the sour lye, the emulsion, hangs the emulsion and the liquid metal, such as liquid, also may transport the liquid, the mixture of gas and liquid containing suspended solids.
Rexroth pumps usually according to the principle of work is divided into positive displacement rexroth pump, power and other types of rexroth rexroth pump pump three categories.In addition to the classification according to the working principle,
Can also be classified and named by other methods.Such as, according to the driving method can be divided into electric and hydraulic rexroth rexroth pump pump etc.
According to the structure can be divided into single-stage and multistage rexroth rexroth pump pump;According to the purpose can be divided into the boiler feed water and metering rexroth rexroth pump pump etc.
According to the nature of the liquid can be divided into water rexroth rexroth pump, oil pump and mud rexroth pump, etc
Rexroth hydraulic pump category:
REXROTH REXROTH plunger pump, gear pump, REXROTH vane pump, REXROTH solenoid valve,
REXROTH reversing valve, oil pump REXROTH, REXROTH guide rail, REXROTH in the hydraulic,
REXROTH REXROTH ball screw, the slider, REXROTH proportional valve, REXROTH pressure valve,
REXROTH REXROTH sensors, motors, REXROTH servo valve, REXROTH relay,
When using the pneumatic diaphragm pump operation should pay attention to the following:
1, ensure the fluid contained in the large particles less than zui pump with particle diameter zui big safety standards.
Not more than 2, inlet pressure of the pump, zui allows the use of high pressure is higher than the rated pressure of the compressed air can cause personal injury and property loss and damage to the performance of the pump.
3, to ensure that the pump pressure pipeline system can withstand the achieved zui high output pressure, guarantee the normal work of the drive gas circuit system of cleaning and conditions.
4, an explosion caused by spark may cause personal casualty and property loss, according to the need to use enough large cross-sectional area of the wire,
Hydraulic pump motor before debugging matters needing attention:
-A20V pump designed for use in open loops.
- Project planning, assembly and commissioning of axial plunger components must be carried out by qualified personnel.
- Working line oil ports and functional oil ports are designed for hydraulic lines only.
- During and shortly after operation, there may be a risk of burn to axial plunger elements, especially electromagnets. Appropriate safety measures (e.g. wearing protective clothing) should be taken.
- The characteristics of the axial plunger element may change according to different operating conditions (operating pressure, oil temperature).
- Pressure oil port:
Oil ports and fixed threads are designed for maximum specified pressure. The machine or system manufacturer must ensure that the safety factors of the connecting elements and lines meet the specified operating conditions (pressure, flow, hydraulic fluid, temperature).
- The data and instructions contained here must be followed.
- Use the following tightening torque:
· Threaded hole of axial plunger element:
The maximum allowable tightening torque MG Max is the maximum for threaded holes and shall not exceed this value.
