Changzhou LangO Machinery and Technology Co.,Ltd is a professional lubrication pump manufacturer and exporter in china, that is concerned with the design, development and production of lubrication equipment.

 

Overview

It applies to motor driven terminal type centralized lubricating system. The electric control cabinet receives the signal sent out by type PV-2E pressure control valve so as to realize alternate grease supply and opening of two main grease supply pipelines.

Cylinder-shaped sliding valve structure is employed to keep tight opening and closing of valve mouth thus realizing long-time high pressure without leakage. Powerful electromagnet and spring is employed to buffer, thus ensuring reliable reversal.

Use instruction

The cone penetration of used lubricating grease is 310-385 (NLG10#~1#).

It can be used directly when the pressure in the grease conservator (pressure at grease returning port) is under 3Mpa. External grease discharge way should be taken when the pressure is between 3~10Mpa.
