Hydraulic motors are divided into high-speed hydraulic motors and low-speed hydraulic motors. They are widely used in many aspects. The manufacturer told us that they are convenient to use and suitable for high-speed hydraulic motors. First, its adjustment sensitivity is very high: due to special structural design and composition, high-speed hydraulic motors generally have high adjustment sensitivity, especially in speed adjustment Cycloidal motor of overhead crane Manufacturer This is especially true during the integration and commutation. In this way, the user can make the motor itself respond sensitively and enter the corresponding working state through simple operation when using the motor. Second, get up Suzhou Manufacturer It is very convenient to move and brake: because the high-speed hydraulic motor has the characteristics of high speed and small moment of inertia, it can easily enter the corresponding state when starting and braking in application. This convenience is an important part of its convenient application. High speed hydraulic motor has many advantages, which brings us great convenience.
System for fixed equipment. This hydraulic system is mostly an open cycle system, including machine tools (workpiece clamping, worktable feeding, direction exchange, spindle drive), presses (pressing, blank holder, direction exchange, workpiece ejection), die-casting machines and injection molding machines (mold closing, demoulding, preforming, injection mechanisms), medical devices, garbage compression and other mechanical devices Suzhou special-purpose System of standby and working devices. The hydraulic system for traveling equipment includes both open circulation system and closed circulation system, including vehicle driving (traveling drive, steering, braking and working equipment Cycloidal motor of overhead crane Manufacturer ), material conveying, loading, unloading and conveying equipment (conveying mechanism, transposition mechanism), various systems of aviation, space and navigation engineering.
1. Pascal principle: also known as static pressure transmission principle, it refers to the pressure exerted on the static liquid in a closed container is transmitted to all points of the liquid at the same time with equal value. The hyperbolic cosine of 2. The hyperbolic cosine of 2. System pressure: the discharge pressure of the hydraulic pump in the system. The hyperbolic cosine of 3. The hyperbolic cosine of 3. Servo valve and proportional valve: infinitely adjust the output of hydraulic valve, such as pressure, flow and direction, by adjusting the input electrical signal analog quantity. (Servo valve also has pulse special-purpose Cycloidal motor of overhead crane Wide modulation input mode). But the structure of these two valves is completely different. The servo valve controls the work of the torque motor by adjusting the electrical signal to deflect the armature and drive the front valve to work. The front valve control oil enters the main valve and drives the valve core to work. The proportional valve regulates the electrical signal to make the electric iron shift, drive the pilot valve core, drive the control oil generated, and drive the main valve core. The hyperbolic cosine of 4. The hyperbolic cosine of. Suzhou Cycloidal motor of overhead crane Kinematic viscosity: the ratio of dynamic viscosity μ to the liquid density α. The hyperbolic cosine of 5. The hyperbolic cosine of 5. Fluid power: the force exerted by the flowing liquid on the solid wall to change the flow velocity.
Its basic types are gear type, screw type, vane type and axial plunger type. Its main characteristics are high speed, small moment of inertia, convenient starting and braking, adjustment (speed adjustment and special-purpose Cycloidal motor of overhead crane Reversing) High sensitivity. As the output torque of high-speed hydraulic motor is generally small, it is also called high-speed small torque hydraulic motor. Its basic type is radial plunger type, in addition, there are axial plunger, vane type, gear type and other structural types. Low speed hydraulic motors are mainly characterized by large displacement, large volume and low speed (sometimes Cycloidal motor of overhead crane Manufacturer It can rotate a few revolutions per minute or even a few revolutions per minute), so it can be directly connected to the working mechanism; It does not need a speed reducer, greatly simplifying the transmission mechanism. Usually, the output torque of low-speed hydraulic motor is large, so it is also called low-speed high torque hydraulic motor.
The output pressure of the hydraulic motor also depends on the load. Rated pressure Pn: the rated pressure refers to the working pressure that the hydraulic motor can withstand during continuous operation. It can special-purpose Cycloidal motor of overhead crane To ensure the volumetric efficiency and service life of the hydraulic motor. Working pressure P: the working pressure is the actual pressure of oil input when the hydraulic motor is working Cycloidal motor of overhead crane Manufacturer power. Its value depends on the size of the load. However, the maximum working pressure is determined by the safety valve in the hydraulic system. The throttle adjustment value must not exceed the maximum pressure value of the hydraulic motor. The third is the maximum pressure: the limit pressure that the motor is allowed to overload in a short time. Pn ≤ Pmax value.
