INGCO S-PW-PA-HPWR14008-SP4-A, High Pressure Washer- Pump Assy( S-PW-PA-HPWR14008-SP4-A)

product details:

A pressure washer’s pump assembly is the heart of the system, responsible for converting mechanical energy from the motor into the high-pressure water flow that creates the cleaning power. Here’s a detailed description of its key components and how they work together:

Components:

A typical high-pressure washer pump assembly consists of several crucial parts:

• Drive Mechanism:
  • Motor (Electric or Gas): Powers the pump assembly, either through an electric motor for electric pressure washers or a gasoline engine for gas-powered models.
  • Coupling: Connects the motor’s shaft to the pump crankshaft, transferring rotational force.
• Pumping Mechanism:
  • Crankshaft: Rotates due to the transferred power from the motor.
  • Connecting Rod: Converts the crankshaft’s rotational motion into reciprocating (back-and-forth) movement.
  • Piston(s): Move within a cylinder as the connecting rod translates the crankshaft rotation.
  • Cylinder and Head: Form a sealed chamber where the pistons operate.
• Valves:
  • Intake Valve: One-way valve that allows water to enter the pump chamber during the intake stroke of the piston.
  • Discharge Valve: One-way valve that controls the high-pressure water flow out of the pump and towards the spray nozzle.
• Unloader Valve (Optional): A safety valve that protects the pump from excessive pressure by releasing bypass flow when the trigger is not engaged.
• Pressure Relief Valve (Optional): Another safety valve that releases pressure if it exceeds a preset limit.
