The governor is composed of several parts, and the components of the governor are composed

What role does the transmission interlock mechanism do?

Answer: The function of the transmission interlock mechanism is to ensure that the clutch must be completely disengaged first when shifting gears to avoid automatic disengagement during work.

The governor is composed of a speed adjustment potentiometer, a speed sensor, a controller, an actuator and a fuse circuit. An electronic governor is a control device that controls the speed of a generator. It is based on the received electrical signal, through the controller and actuator to change the size of the fuel supply of the fuel pump.

1. Speed sensor: The speed sensor should collect the highest possible signal frequency. The highest signal frequency is 12,000 pulses per minute.

The relationship between engine speed and frequency is calculated as follows: f = nz 60, where f is the frequency (hz), n is the speed of the engine (r min), z is the sensing gear teeth (or the number of teeth in the outer ring of the flywheel). It is best to measure the rotational speed of the sensor from the flywheel, and the gap between the sensor and the top of the flywheel ring gear is the controller when installing

The function of the controller is to compare the actual speed value measured by the sensor with the set value, and drive the actuator to perform the control action. 3. Speed adjustment potentiometer: The speed adjustment potentiometer adjusts the frequency according to the maximum allowable speed used by the engine.

If the operating frequency of the engine is specified at the time of ordering, the factory will adjust the frequency according to the requirements. If the operating frequency of the unit is not indicated on the order, the frequency is set to 2000Hz when leaving the factory. If this frequency is set between the engine's idle and maximum revs, the engine can be started and the "speedmax" potentiometer can be adjusted to achieve the highest operating frequency of the engine.

4. Actuator: The actuator is mainly composed of DC motor, transmission gear, output shaft and feedback components. The actuator is driven by a DC motor, and its torque is transmitted to the output shaft via an intermediate gear.

The feedback component transmits the working state of the actuator to the controller to form a closed-loop control system. The output shaft rocker arm of the actuator is connected to the fuel injection pump tooth rod by means of an adjustment link. 5. Stove burning risk circuit:

There is a fuse circuit in the electronic speed control system, when the sensing signal is interrupted, such as when the engine stops running due to cable breakage, it can stop the actuator from working, and restore the rocker arm of the output shaft to the "0" position. Hunger Hood.

A DC governor is usually composed of the following main components:

1.Rectifier: A device that converts alternating current into direct current.

2.Filter: The function of the filter is to filter the DC output of the rectifier, so that the ripple coefficient of the DC is reduced and a stable DC is obtained.

3.Inverter: An inverter is a device that converts direct current into alternating current, which can control the frequency and phase of alternating current.

4.Controller: responsible for controlling the speed, steering and stopping of the motor, usually including the main control board, interface board and dynamic brake and other modules.

5.Radiator: The operation of components such as inverters and rectifiers all need to consume energy, which will generate a certain amount of heat, and the radiator can dissipate heat to avoid overheating and burning.

6.Protector: It mainly includes over-current protection, over-voltage protection, under-voltage protection, over-heat protection and other protection mechanisms to protect the normal sail destruction operation of the governor and motor, and avoid the occurrence of failures and dangers.

These components can vary depending on the specific type and functional requirements of the scale-up residual combustion speeder.

The governor is an automatic adjustment device, which automatically adjusts the fuel supply of the fuel injection pump according to the speed change when the diesel engine is working, so as to stabilize and control the speed of the diesel engine, so that the diesel engine can run stably under different working conditions. Speed controllers have been widely used in industrial DC motor speed regulation, industrial conveyor belt speed regulation, lighting regulation, computer power heat dissipation, DC fans, etc.

The basic principle of the governor: changing the amount of diesel entering the cylinder for combustion (increasing or closing the "throttle"), you can change the speed or load of the diesel engine. If the speed is kept constant, changing the amount of fuel can change the load of the diesel generator; If you keep the load of the diesel generator unchanged and change the amount of fuel, you can change the speed of the diesel engine.

The governor is to change (or adapt) the load of the diesel generator while keeping the speed constant.

According to its different working principles, it can be divided into mechanical, pneumatic, hydraulic, mechanical-pneumatic compound, mechanical-hydraulic composite and electronic and other forms. However, the most widely used is the mechanical governor, which has a simple structure, reliable work and good performance.

The governor is used to keep the speed of the diesel engine stable. In the process of load change of diesel pulse, its speed will change accordingly. When the speed is reduced to the base branch, if the governor is not adjusted, the diesel engine will eventually stop; When the speed increases, if the governor does not work, the diesel engine will eventually be unable to withstand excessive centrifugal force and be damaged.

The function of the governor is to keep the speed of the diesel engine stable. In addition, the governor can also maintain the minimum and maximum speed of the diesel engine to prevent mechanical damage caused by stalling when running at low speed and "flying" during high speed operation.

The function of the governor is to automatically increase or decrease the fuel supply of the fuel injection pump according to the change of the load of the diesel engine, so that the diesel engine can run at a stable speed. The governor is an automatic adjustment device used to reduce the non-cyclic speed fluctuations of some machines, so that the machine speed can be kept at or near the set value.

The precautions for using the governor are: 1. In the thunderstorm season, strong lightning strikes will cause instability of the power grid, and it is easy to break down the thyristor module and burn out the fuse. 2. After the power supply is disconnected, continue to carry dangerous voltage on the absorber capacitor, and do not turn on the governor for at least 2 minutes.

The governor is an automatic adjustment device, which can automatically increase or decrease the fuel supply of the fuel injection pump according to the change of the load of the diesel engine, so that the diesel engine can run at a stable speed.

Speed regulators have been widely used in industrial DC motor speed regulation, industrial conveyor belt speed regulation, lighting mediation, computer power heat dissipation, DC fans, etc.

The functions of the governor are: (1) adjusting the speed of the unit. 3) When the units are running in parallel, the load between the units is automatically distributed.

The steam turbine speed regulation system is composed of four parts: the speed sensing mechanism, the transmission amplification mechanism, and the steam turbine speed regulating system is composed of four parts: the speed sensing mechanism, the transmission amplification mechanism, the steam distribution mechanism and the feedback mechanism.

The speed sensing mechanism converts the rotational speed signal of the rotor into a primary control signal.

The transmission amplification mechanism amplifies the power of the primary control signal. And according to the purpose of adjustment for the control operation to generate the control signal of the oil engine.

The steam distribution mechanism is to transform the stroke of the oil motor into the opening of each adjusting valve, through the nonlinear transmission characteristics of the steam distribution mechanism, through the nonlinear transmission characteristics of the steam distribution mechanism, the steam intake of the steam turbine and the oil motor process are corrected to an approximate linear relationship.
