Classification FMB-BLICKLE hydraulic pump classification Common FMB BLICKLE hydraulic pump types: 1, according to whether the flow can be adjusted can be divided into: variable and quantitative pumps. Output flow can be adjusted according to the needs of the variable pump, called the quantitative pump can not be adjusted. 2, according to the hydraulic system commonly used pump structure is divided into: gear pump, vane pump and plunger pump 3 kinds. FMB BLICKLE gear pump: smaller size, simple structure, less stringent requirements on oil cleanliness, cheaper prices; but the pump shaft unbalanced force, serious wear and tear, leakage larger. FMB BLICKLE vane pump: divided into double-acting vane pump and single-action vane pump. This pump flow uniform, smooth operation, low noise, pressure and volumetric efficiency than the gear pump, the structure is more complex than the gear pump. FMB BLICKLE piston pump: high volumetric efficiency, small leakage, can work under high pressure, mostly used in high-power hydraulic system; but the structure is complex, the material and processing precision are high, expensive and demanding on oil cleanliness. Generally FMB BLICKLE gear pump and FMB BLICKLE vane pump can not meet the requirements FMB BLICKLE plunger pump. There are some other forms of FMB BLICKLE hydraulic pump, such as screw pumps, but the application is not as good as the above three kinds of general. FMB BLICKLE hydraulic pump working principle and performance parameters for the hydraulic drive to provide a hydraulic fluid pressure of a component, is a pump. Its function is to convert the mechanical energy of power machines (such as electric motors and internal combustion engines) into liquid pressure energy. FMB BLICKLE single piston pump works. Cam driven by the motor rotation. As the cam pushes the plunger up, the seal formed by the plunger and the cylinder decreases in volume, the oil is squeezed out of the sealed volume and drained through the check valve to where it is needed. When the cam rotates to the descending part of the curve, the spring forces the plunger downward to create a degree of vacuum, and the oil in the tank enters the sealed volume under atmospheric pressure. The cam continuously raises and lowers the plunger, periodically reduces and increases the volume of the seal, and the pump continues to suck and drain oil. The FMB BLICKLE hydraulic pump is a power element of a hydraulic system. Its function is to provide the hydraulic system with pressure oil. In energy conversion, it converts the mechanical energy output from the prime mover (such as an engine) to the pressure energy of the fluid that is easy to transport. The FMB BLICKLE hydraulic motor is an actuator that converts the pressure of the input fluid into mechanical energy that the output shaft rotates to draw the load. According to the structure, FMB BLICKLE hydraulic pump and hydraulic motor can be divided into gear, FMB BLICKLE blade, plunger and other types. 1.FMB BLICKLE hydraulic pump pressure FMB BLICKLE hydraulic pump working pressure is the pump (or motor) in the actual work output (or input) the pressure of the oil, determined by the external load. Rated pressure is under normal working conditions, according to test standards for continuous operation of the maximum pressure. Its size is limited by life, if more than rated pressure work, the pump (or motor) life will be shorter than the design life. When the working pressure is greater than the rated pressure overload. 2. Speed ​​FMB BLICKLE Working speed refers to the pump (or motor) in the actual rotation speed. Rated speed is the rated speed, continuous operation for a long time the maximum speed. If the pump exceeds the rated speed work will result in insufficient oil absorption, vibration and loud noise, parts will suffer cavitation damage, reduce life expectancy. The minimum stable speed is the minimum speed that the motor can run normally. At this speed, the motor does not appear to crawl. 3. Displacement, flow row FMB BLICKLE volume refers to the pump (or motor) per revolution, from the sealed chamber geometry changes in the volume of discharge (or input) of liquid volume, commonly used units ml / r (ml / ). Displacement by changing the variable pump (or variable motor), the displacement can not change into a quantitative pump (or quantitative motor). The actual flow is the flow at the outlet (or inlet) when the pump (or motor) is in operation. Due to internal leakage of the pump itself, FMB BLICKLE has an actual flow less than the theoretical flow. Because the motor itself also has internal leakage, to achieve the specified speed, in order to compensate for the leakage, the actual input flow must be greater than the theoretical flow. 4. Efficiency Volumetric efficiency, the hydraulic pump refers to the actual flow and the ratio of the theoretical flow. The hydraulic motor refers to the theoretical flow and the actual flow ratio. Mechanical efficiency, hydraulic pump refers to the theoretical torque and the actual input torque ratio. The actual output of the hydraulic motor torque torque theoretical torque to overcome the friction torque, so its mechanical efficiency is the ratio of the actual output torque and theoretical torque. Total efficiency is the pump (or motor) output power and input power ratio. The total efficiency is equal to the product of volumetric efficiency and mechanical efficiency. FMB BLICKLE performance parameters FMB BLICKLE hydraulic pump is a hydraulic system of power components, its function is to provide hydraulic system pressure oil, energy conversion point of view, it will be the original motor (such as engine) output mechanical energy is converted to liquid Pressure energy. The hydraulic motor belongs to the actuator, which can convert the pressure of the input liquid into the mechanical energy of the output shaft to rotate, which is used to drag the load to do work. According to the structure of the form, hydraulic pump and hydraulic motor can be divided into gear, vane, plunger and other types. 1.FMB BLICKLE hydraulic pump pressure FMB BLICKLE hydraulic pump working pressure is the pump (or motor) in the actual work output (or input) the pressure of the oil, determined by the external load.
