In the context of a hydraulic pump system, positive control and negative control refer to different methods of regulating or controlling the operation and performance of the pump. Here’s what each term generally means: Positive Control: Definition: Positive control typically involves directly commanding or regulating the hydraulic pump to achieve a desired output or performance. Example: In a positive control system, a controller or valve mechanism actively adjusts the pump's speed, flow rate, or pressure to maintain specific operating parameters. This could involve using feedback sensors to monitor pressure or flow and adjusting the pump's output accordingly. Negative Control: Definition: Negative control, on the other hand, often involves using feedback from the system to control or limit the pump's output indirectly. Example: A common application of negative control is in pressure relief valves. These valves are set to open and relieve pressure in the hydraulic system when it exceeds a certain threshold. By releasing excess pressure, they indirectly control the pump's output by preventing it from generating excessive pressure that could damage the system. Application in Hydraulic Systems: Positive Control System: Purpose: Used when precise control over the pump's output parameters (such as flow rate or pressure) is required. Components: Typically involves electronic or mechanical controllers that receive input signals (e.g., from sensors) and adjust the pump's operation accordingly. Advantages: Offers precise control and can adapt to varying demands in real-time. Negative Control System: Purpose: Primarily used for safety and protection of the hydraulic system. Components: Pressure relief valves are a common example. They are set to open when the pressure exceeds a safe limit, diverting excess fluid away from the pump and preventing damage. Advantages: Provides a fail-safe mechanism that protects the system from overpressure conditions.
Tks bro, very little content is available on the subject, kindly explore more on hydraulic flow regulations & hydraulic system in excavator..wishing you all the best.🙏
Orbi ways ha check karna ka running machine ko band kardo or phir guage dakho aapki needle guage ki slowly slowly down hogi or jetna acculator charge hoga eska baad ak daam jatka sa necha aajagi
very nicely explained
Thank you so much 🙂
wonderful video sir
Thank you so much 🙏 brother
Nice information
Thank you so much
KINDLY GIVE A DESCRIPTION ABOUT POSITIVE CONTROL & NEGATIVE CONTROL SYSTEM IN HYDRAULIC PUMP

Ok

Sb ke apne tarike he
Check valve hay 25 kase dekhaga
Bhaisahab video ko dhyan se dekho jb pump running me hoga to check valve ko open kr ke rakhega or usi waqt hme wo pre charge pressure milega
Aap mera check valve wala video bhi ja ke dekh skte ho ap ko samajh me a jayega ki ye check valve kese kam krta he
video dekhne ke liye dhanyawaad 🙏
@@JPhydrauliccircuit right 👍
