Product Description
The types of plunger couples produced by Huahui Oil Pump and Nozzle Company include: BQ series, No. I series, No. II series, A series, AK series, AD series, P series, and high-pressure common rail series, with diameters ranging from 5 to 18 mm. With inclined grooves and spiral grooves with different leads and different rotational directions, the product can meet the needs of oil pumps for diesel engines with different performances.
The plunger couple consists of a plunger and a plunger sleeve, and is a key precision component of the fuel injection pump. It is made of high-quality alloy steel and finely processed, with a matching gap of 0.0015 - 0.0025mm. Under the action of the oil pump cam, the plunger reciprocates at high speed, accurately supercharges the fuel, controls the amount of oil and supply timing, and ensures stable and efficient operation of the engine.
Product Introduction
The CB28 Plunger is a precision-engineered fuel injection component designed for use in high-pressure diesel fuel systems. As a critical part of the fuel pump, the plunger operates through a reciprocating motion to pressurize fuel and deliver it into the combustion chamber at precise intervals. Made from wear-resistant alloy steel and treated with advanced heat treatment processes, the CB28 Plunger ensures high durability, minimal leakage, and consistent fuel delivery performance under demanding conditions. It is widely used in agricultural, industrial, and construction diesel engines.
Product Advantages
High Pressure Resistance: Designed to operate under extremely high pressures, ensuring efficient atomization and combustion.
Precision Manufacturing: Tight tolerances and fine surface finish reduce friction, improve fuel delivery accuracy, and minimize leakage.
Wear-Resistant Materials: Made from high-strength alloy steel with advanced surface hardening for extended service life.
Fuel Efficiency: Enhances combustion efficiency, contributing to better fuel economy and lower emissions.
Versatility: Compatible with various types of fuel injection pumps and engine models.
Product Applications
The CB28 Plunger is commonly used in the following applications:
Agricultural Equipment: Fuel systems in tractors, harvesters, and irrigation machines.
Construction Machinery: Diesel engines in excavators, bulldozers, loaders, and other heavy equipment.
Industrial Engines: Stationary engines in generators, compressors, and industrial machinery.
Marine Engines: Auxiliary or primary diesel engines in small boats and vessels.
Automotive Diesel Engines: Older models of commercial trucks and utility vehicles with plunger-type fuel systems.
FAQ
How long is your delivery time?
One week for spot goods, 60 days for orders
What is your MOQ?
100 pieces
Can you design the equipment according to our size?
Yes
Can the CB28 plunger be used in modern common rail systems?
No, the CB28 is designed for traditional plunger-type fuel injection systems, not for modern common rail technology.
How long does a CB28 plunger typically last?
With proper fuel filtration and maintenance, the plunger can last several thousand hours, depending on the operating environment.
What causes plunger wear or failure?
Common causes include dirty fuel, lack of lubrication, corrosion, or excessive operating pressure beyond design limits.
Is the CB28 plunger interchangeable with other models?
It depends on the specifications of the fuel pump and engine. Always refer to the engine or pump manufacturer’s compatibility list.
