Q1. How does a load sensing pump work ?
Ans. 
A load sensing pump adjusts its flow rate based on the load demand to optimize energy efficiency.
• A load sensing pump has a pressure compensator that adjusts the flow rate based on the load pressure.

• It senses the load pressure and adjusts the pump displacement to meet the demand.

• This helps in reducing energy consumption and improving overall system efficiency.

• Examples of load sensing pumps include variable displacement

Q2. Reasons why hydraulic system gets slow ?
Ans. 
Possible reasons for a hydraulic system to get slow include fluid leaks, air in the system, worn out components, and contaminated fluid.
• Fluid leaks in the system can lead to a decrease in pressure and flow rate.

• Air trapped in the system can cause inefficiencies and reduce the system's performance.

• Worn out components such as seals, valves, or pumps can result in decreased efficiency.

• Contaminated fluid with debris or par...read more

Q3. How does proximity sensors work ?
Ans. 
Proximity sensors work by detecting the presence or absence of an object without physical contact.
• Proximity sensors emit electromagnetic fields or beams of radiation to detect the presence of an object.

• When an object enters the sensor's field, it reflects the radiation back to the sensor, triggering a response.

• There are different types of proximity sensors such as inductive, capacitive, ultrasonic, and photoelectric se...read more
