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.
Plunger couple is an important part of engine fuel injection. It consists of a plunger and a plunger sleeve, made of high-temperature resistant alloy, with a matching gap of about 0.0015 - 0.0025mm. With precise cooperation, high-speed movement in the high-pressure oil pump can accurately control the fuel injection amount and time to help the engine operate efficiently.
