The control valve consists of two main assemblies: valve body assembly and actuator assembly (or actuator system), which are divided into four series: single seat series regulating valve, double seat series regulating valve, sleeve cylinder series regulating valve and automatic series regulating valve.
Automobile harness is the main body of automobile circuit network. Without harness, there would be no automobile circuit. harness refers to the copper perforated contact terminals (connectors) and crimped wires and cables, which are then combined with the harness to form a component connecting the circuit.
The control valve is the actuator in the automatic control, and its application quality is directly reflected in the control quality of the system. As a final element in process control, people have a newer understanding of its significance than in the past.
hydraulic pump adjusts the power of the pump. Clockwise adjustment means an increase in power, counterclockwise adjustment means a decrease. The formula: Power is equal to pressure multiplied by the flow rate. Under the condition that the motor speed is constant and the pressure is constant, the greater the power, the higher the pump power is. The more traffic is spent. It should be noted that both pumps should be set together with 90° as the setting value.
The gear pump consists of two gears, the pump body and the front and rear covers to form two enclosed spaces. As the gears rotate, the volume of space on the side of the gear displacement increases from small to large, creating a vacuum to suck in the liquid, and the volume of space on the side of the gear engagement increases the larger it becomes smaller, and the liquid is pushed into the pipeline. The intake cavity and the ejection cavity are separated by the engagement line of the two gears. The pressure at the output of the gear pump depends solely on the resistance at the pump output.
The gear pump is simple and compact in construction, small, light, good in manufacturability, cheap in price, strong in self-priming, insensitive to oil pollution, large in speed range, able to withstand shock loads, convenient in maintenance and reliable in operation. The gear pump is a rotary pump that depends on the change and movement of the work volume formed between the pump cylinder and the combing gear to transport liquid or put pressure on it.
The control valve consists of two main assemblies: valve body assembly and actuator assembly (or actuator system), which are divided into four series: single seat series regulating valve, double seat series regulating valve, sleeve cylinder series regulating valve and automatic series regulating valve.
The regulator compares the measured value of the parameters of the production process with the given value, and after the deviation is obtained, an output signal is generated according to a certain adjustment rule to push the actuator to eliminate the deviation, so that the parameter is kept near the given value or changes according to a predetermined rule. controller.
