the pg电子下载-pg电子游戏 are also rated in several other ways as well. hydraulic motors are used for many applications now such as winches and crane drives, wheel motors for military vehicles, self-driven cranes, and excavators. conveyor and feeder drives, mixer and agitator drives, roll mills, drum drives for digesters, trommels and zhongyiyepk kilns, shredders for cars, tyres, cable and general garbage, drilling rigs and trench cutters.
this will include the displacement of the motor, which can be fixed or variable. displacement in general refers to the volume of the hydraulic fluid that is required to turn the shaft of the motor, which is what provides the mechanical power of the motor. generally this is measured in inches cubed or centimeters cubed. the higher the displacement the more liquid that is required but also the more power generated. fixed displacement motors have the same torque at all motor speeds. a variable displacement motor allows for different speeds and torque, which allows the motor to adjust output based on the load on the system.
each motor also has a pressure rating, which is the maximum pressure that the motor can be operated at. if used in systems with more pressure than the rating there is a much greater likelihood of leaking within the motor and increased risk of damage to the motor. having the right pressure rating is essential-- it is acceptable to go higher but going lower is a huge risk.
hydraulic motors are also designed for specific viscosities or thicknesses of oil or liquid within the system. oil temperature is also an important consideration, especially when operating in industrial types of applications or in high temperature settings. the viscosity rating is critical if the equipment is to be operated in very cold weather since oil has to be adjusted to a lighter weight oil in cold temperatures to keep it flowing through the sealed system.
measuring the dimensions of the various hydraulic motors that meet specifications can also be an essential consideration, especially for replacement motors. there are some very compact, high power motors now available, so you do have options as to the height, length and width of the motor as well as the specific shaft length required.
