A summary
DRB - L series of electric lubrication pump is suitable for lubrication, wide distribution points for the high frequency of oil, double type dry oil lubrication system. Through the two-lane distributor for lubrication part to grease, can satisfy the needs of all kinds of machinery and equipment for the large-scale production, and particularly appropriate.
This series can be composed of electric lubrication pump double ring type lubrication system, which composed of the system, the annular arrangement of lubrication pump returns at the end of the main control hydraulic pressure system, make two main directional control valves for alternately the grease lubrication system, See appearance and shape dimension. Also can make double terminal type lubrication system, which consists of the main terminal to control the pressure control of electromagnetic valve. Reversing valve alternately to two main for the centralized grease lubrication system, and also see appearance and shape dimension regulation.
This series of electric lubrication pump adopt double plunger, reliable operation, deceleration institutions in the pump body, compact structure, small volume, with corresponding electric can realize the automatic control.

Third, the model shows

Four, the graph symbols

Five, wiring instructions

Six, principle of work

This series of electric lubrication pump plunger pump, the reservoir, reversing valves, motor parts. Plunger pump driven by motor in from the reservoir pressure to inhaled grease, directional control valves, through the reversing valves along two alternately the oil conveying out, when a mouth to mouth oil pressure to send out, another a grease and oil storage oil on unloading.
Ring structure of electric lubrication pump hydraulic reversing valves, with four interface, external two respectively by two fuel charge for the return of coiled tubing, rely on the back of the hydraulic oil tubing in promoting reversing valve commutation.
Terminal type structure of electric lubrication pump with electromagnetic reversing valves, there are two interfaces, external two competent, rely on the fuel and electricity realize electromagnet directional injection.
Plunger pump reversing valve movements in principle of instructions.

Seven instructions

1, this series of electric lubrication pump should be installed in the environment temperature, dust, small vibration, easy less adjustment, inspection, maintenance and grease filling and possible convenient place in the center of the system arrangement, shorten the length of pipe system, keep the lowest pressure drop, can produce enough to overcome the stress resistance at lubrication.
2 before use, to the plunger pump deceleration cavity N220 industrial gear oil to add oil standard stipulated surface.
3 and the reservoir for use in DJB - V70 lipid type electric pumps from lubrication pump for the supply of the mouth, use should be clean, do not allow grease mixed dirt.
4 the turning direction and lubrication pump is one-sided, must use according to the motor of the provisions on to spin to the wiring. Spin
Five, the pump pressure relief valve for the standard set 23MPa, can 20MPa range from 0 ~ arbitrarily regulate, when use does not allow more than 15% of the nominal pressure pump 23MPa (.).
6 and ring type lubrication pump hydraulic pressure of reversing valve setting 5MPa press set.
7, this series of electric lubrication pump for indoor or outdoor installation, in applications use, must adopt preventive measure.

Use medium for the cone not less than 25 ° c, 150g 265 (1) of the NLGI0 10mm/grease (2 - # # #).
