Product details

The accessories of plunger pumps encompass multiple critical components that collaborate to ensure the pumps' efficient and stable operation. Below is a detailed introduction to the accessories of plunger pumps:

I. Main Structural Components

Pump Body

Function: The pump body primarily serves to accommodate and support other components, forming a closed working chamber.

Material: Typically made of high-strength, wear-resistant materials such as cast iron or steel.

Plunger

Function: The plunger is the core component of the plunger pump, performing reciprocating motion to draw in and discharge liquid.

Material: Commonly made of high-strength, corrosion-resistant materials such as cast iron, steel, or stainless steel.

Characteristic: The plunger requires a high surface precision to reduce wear and leakage.

Cylinder Block

Function: The cylinder block provides the space for the plunger to move, and its bore precision directly affects the smoothness and sealing of the plunger's motion.

Material: Usually made of wear-resistant, corrosion-resistant materials.

Backplate

Function: The backplate is tightly connected to the pump body, serving to mount and support the plunger.

Material: Typically made of high-strength materials such as steel.

II. Key Functional Components

Seals

Function: To prevent liquid leakage within the pump, ensuring the pump's working pressure and efficiency.

Material: Often made of corrosion-resistant, wear-resistant materials such as rubber or polytetrafluoroethylene.

Springs

Function: To provide the plunger with resetting force and a certain preload, ensuring stability during reciprocating motion.

Characteristic: The stiffness and preload of the spring need to be matched according to the pump's working pressure and flow rate.

Valves (Suction Valve and Discharge Valve)

Function: To control the inlet and outlet flow of the pump, ensuring smooth suction and discharge of liquid.

Material: Usually made of wear-resistant, corrosion-resistant materials.

Characteristic: The flexibility of valve opening and closing has a significant impact on pump performance.

III. Auxiliary Components

Drive Device

Function: To provide power for the plunger pump, driving the plunger to perform reciprocating motion.

Type: Common drive devices include electric motors, engines, etc.

Leakage Pipeline

Function: To redirect liquid that has not been pumped out of the pump chamber back to the inlet, preventing leakage.

Design: The design of the leakage pipeline needs to consider liquid fluidity and pump working pressure.

Other Auxiliary Components

Such as connecting pieces, fasteners, lubrication devices, etc. Although these components do not directly participate in the pump's working process, they are crucial to the pump's overall performance and stability.

In summary, plunger pump accessories are diverse, with each part playing an indispensable role. When purchasing or replacing accessories, it is important to ensure that their material, performance, and precision meet the pump's operational requirements, to guarantee the pump's efficient and stable operation.
