1. Overview

DRB-J series electric lubrication pump is suitable for double-line injection centralized lubrication system with nominal pressure of 10MPa.Dry thin oil lubricationThe lubricating oil output by the electric lubrication pump is quantitatively distributed by the two-line distributor and sent to the injection valve. The input oil pressure automatically opens the check valve of the compressed air pipeline and sprays the lubricating oil into a mist of oil onto the friction parts of the machinery and equipment. It is especially suitable for lubrication of friction parts of machines such as gear tooth surfaces of open gear transmissions, support rollers, sliding guide surfaces, etc.

5. Structural characteristics

This series of electric lubricating oil pumps consists of a plunger pump, an oil reservoir, a hydraulic reversing valve, an accumulator, and an electric motor. Driven by the electric motor, the plunger pump sucks lubricating oil from the oil reservoir and presses it to the hydraulic reversing valve. The reversing valve has four interfaces, two external oil supply main pipes and two oil supply main pipes leading back respectively. The oil return pipe relies on the pressure of the lubricating oil in the oil return pipe to push the hydraulic reversing valve to alternately transport the lubricating oil out along the two oil outlets. When one oil outlet pressure delivers grease, the other oil outlet is in contact with the oil storage port. The accumulator is connected to unload, and the two oil ports of the accumulator are connected in parallel with the two oil supply outlets of the reversing valve, so that the oil supply can be replenished in time immediately after the pipeline is reversed for oil supply.

8. Instructions for use

1. This series of electric lubrication pumps should be installed in an environment with suitable ambient temperature, less dust, small vibration, ventilated and dry, and convenient for oil replenishment, adjustment, inspection and maintenance. If used outdoors or in harsh environmental conditions, protective measures should be taken.

2. To fill the oil reservoir with lubricating oil, an electric refueling pump should be used.Smart lubricationPump supply port injection. (A filter is installed in the supply port).

3. Before the lubrication pump is operated, lubricating oil (industrial gear oil N220) must be added to the reducer cavity of the pump to reach the specified oil level. The lubricating oil in the reducer cavity must be added every 200 hours after the lubrication pump is put into use. Check for replacement.

4. The rotation direction of the lubrication pump is one-way. When used, it must be connected according to the rotation direction specified on the rotation direction plate on the motor.

5. The set pressure of the pump's relief valve can be adjusted arbitrarily within the range of 0 to 10MPa. It is not allowed to exceed 10% of the nominal pressure of the pump (11MPa) during use.
