I.Conditions of Use

It is used for electric terminal centralized lubrication system. The electric control cabinet receives the signal from the P V-2E pressure control valve and controls the valve to realize the alternate oil supply and opening of the two oil supply mains.

The cylindrical slide valve structure is adopted to make the valve opening and closing tight and keep high pressure from leaking for a long time. The powerful electromagnet and spring buffer make the commutation reliable.

II.Technical Parameters

III.Instructions for use

The penetration of grease is 310 ～ 385 (NLGI 0 # ~ 1 #)

When the pressure in the oil reservoir (pressure at the oil return port) is less than 3MPa

Connected. When 3 ～ 10MPa, external drain method is needed.

IV.Action description

Position S-1

The picture shows the end of the oil supply. The solenoids a and b of the solenoid valve are de-energized.

The magnetic, pressure oil inlet is closed, and the dry thin oil lubrication pump is stopped. Here

Both fuel supply mains are open to the oil reservoir.

Position S-2

When the pump is started, the electromagnet a is energized to magnetize, and the grease output by the pump

It is sent to the fuel supply supervisor L1 through port A, and the fuel supply supervisor L2 is still open to the oil reservoir.

Position P-1

A pressure control valve is installed at the end of the fuel supply main pipe.

When the set pressure of the pressure control valve is exceeded, push its slide valve to the right.

Position P-2

The slide valve moves to the right, and pulls the contact that is associated with it to the left.

The process switch L S-1 is in the ON state, and sends a signal to the electric control cabinet to make the electromagnetic

The iron a loses power and the pump stops working and returns to position S-1.

The next time oil is supplied, the solenoid b is energized, and the lubricant output by the pump is passed through port B.

Sent to the main oil supply L2, the pressure operated valve actuated the limit switch state.
