1. Overview

This electric refueling pump is suitable for dry oil centralized lubrication systems. It fills lubricant into the oil reservoir of the electric lubrication pump. The pump is a built-in plunger positive displacement pump, which is directly driven by a reduction motor to drive the eccentric to reciprocate. Suction oil function. The pump operates smoothly, has high output pressure, and is equipped with a low oil level alarm device, which can fill the oil cylinder with grease in a timely manner.

2. Technical parameters

The medium used is grease (NLGI 0# ~ 2#) with a cone penetration of not less than 265 (25℃, 150g) 1/10mm or industrial lubricating oil with a viscosity grade greater than N46.

3. Instructions for use

1. Before use, unscrew the oil plug above the housing and add No. 50 mechanical oil to the specified oil level.

2. Rotate the wiring in the direction of the rotation arrow.

3. ConveyedSmart lubricationThe agent must be clean, uniform in texture, and within the specified viscosity range.

4. The nominal pressure of the pump is 3MPa, which has been adjusted before leaving the factory. No further adjustment is required.

5. The inner diameter of the hose supplied from the factory is Φ13, and the external connecting thread is M33×2. If the connecting thread of the lubrication pump filling port is M32×3, use a spare transition joint.

6. This pump is equipped with a low-level alarm device. After alarming, the oil cylinder should be filled with grease in time.

7. Do not run dry without oil in the barrel.

5. Troubleshooting and Troubleshooting

1. No oil discharge:

a. There is air in the lubricant. Loosen the exhaust valve to drain out the air in the lubricant, then tighten the exhaust valve.

b. The oil suction port is stuck with impurities and cannot suck or press oil. Clean the impurities from the oil suction port.

2. Low oil pressure:

a. Check whether the one-way valve in the pump is stuck or damaged by impurities. Clean the impurities in the one-way valve or replace it.

b. Check the seals and pipe joints for leaks, replace the seals, and tighten the joints.
