1. Conditions of use

It is used in the 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 alternate oil supply and opening of the two oil supply main pipes.

The cylindrical slide valve structure is adopted to ensure tight opening and closing of the valve port and maintain high pressure without leakage for a long time. The use of powerful electromagnets and spring buffers ensures reliable commutation.

3. Instructions for use

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

When the pressure in the oil reservoir (oil return port pressure) is below 3MPa, it can be directly

Use directly. When 3~10MPa, external oil drainage method is required.

4. Action description

Location S-1

The picture shows the oil supply end state. The solenoid a and b of the solenoid valve are both powered off.

Magnetic, pressure oil inlet is closed,Dry thin oil lubricationThe pump is out of service. In this state

In this state, both oil supply main pipes are open to the oil reservoir.

Location S-2

When the pump starts, electromagnet A is energized to obtain magnets, and the grease output by the pump

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

Position P-1

A pressure control valve is installed at the end of the oil supply main pipe. When the pressure at the end of the main pipe L1

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

Location P-2

Move the slide valve to the right, pull the contact linked to it to the left, and move the slide valve to the left.

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

When iron a is powered off, the pump stops working and returns to position S-1.

When lubricating next time, electromagnet B is energized, and the lubricant output from the pump is absorbed through port B.

is sent to the oil supply main pipe L2, and the pressure control valve acts to make the travel switch open.
