产品介绍

Product Overview

The HCH series hydraulic lubrication pump is a hydraulic operated double acting piston pump that uses a single-line parallel grease metering component to distribute grease during both the up and down strokes. It is used in conjunction with a circulation timing control system and is commonly used in single-line centralized lubrication systems.

When lubricating grease needs to be added to the lubrication area, the solenoid valve at the front end of the hydraulic lubrication pump is powered on, and the lubrication pump starts working. When the injectors complete the grease filling operation and the pressure in the main pipeline of the system rises to the set pressure, the pressure switch sends a feedback signal to the control system, which cuts off the power supply to the solenoid valve at the front end of the hydraulic lubrication pump. The system releases pressure and enters the next lubrication cycle.
