DRB - P series of electric lubrication pump and device (40MPa)
A summary
DRB - P series of electric lubrication pump lubrication, high frequency suitable pipe length, lubricating points, double the dense dry thin oil lubrication system, as the supply of grease conveying equipment. Still can be equipped with mobile vehicles, hose, oil gun and portable electric cable lubrication pump, suitable for lubrication low frequency, less oil, lubricating points for large quantity, not easy using the machine equipment, centralized grease lubrication grease for moving.
This series for electric pressure lubrication pump plunger type. Working pressure in nominal pressure range can adjust, have double overload protection. With oil storage automatic alarm device, oil lubrication pump if equipped with electric control box can realize the automatic control system of double concentrated lubrication system, and to monitor.

Five, the principle of work
Fixed in gear motor and pump flange, driven by eccentric shaft driving fork as beeline reciprocating motion sliding and driving helical compression plates and scraping oil board rotate clockwise (use), the oil by stirring soften grease evenly by pressure to pump oil absorption around the mouth.
Two groups of piston pump body, each group of piston and work by 1 2 control piston, piston when a group of piston oil absorption process completed work, another group of piston the piston to the oil pressure grease. As the chart shows, when sliding movement, the fork left piston oil absorption, complete set under pressure oil, piston complete set to start the new work cycle. Then next group 1 and 2, piston, piston, 2 to arrive in the spring of the position limit exports, and close to continue the pistons 1, 2, and 1 piston vacuum, vacuum formed between the piston moves left 1 with increasing, slippery fork to limit position piston 1 open mouth from oil absorption, oil absorption grease, such as spring mouth inhaled, don't push to limit the piston and rod, at the fork of 3 will be forced to put the piston driven to limit position, 2 pressure on group at 1, 2, 3, piston, piston, 1 to shut off oil absorption, is inspiratory grease in Detroit 1 of 2, when the piston moves to the mouth open, the oil piston rod 2 and 3 of sports also stopped, the piston moves left, 1 to grease the oil pressure from the mouth, piston, 1, 2 sliding fork to limit movement has finished half of the circulation work position, so live in circulation, two groups of piston alternately grease from the oil pressure to send out, the mouth of the pressure pump flange to the filter for system.
Six, use essentials
1, this series of electric lubrication pump should be installed in the environment right, dust less convenient adjustment, inspection, maintenance and easy unpick and place of grease filling.
2, this series of electric lubrication pump should as far as possible in the center of the system arrangement, shorten the length of pipe system, keep the lowest pressure drop, can produce enough to overcome the pressure of back pressure lubrication points.
3 the pressure-regulating valve, pump pressure, can be set at 0 ~ 40MPa scope to arbitrarily regulate, and when use does not allow more than nominal pressure pump 40MPa (.).
4 and the oil pump inlet strainer filter to regular cleaning, prevent the jams.
5 if, due to the fault reasons, a series of pressure to 50MPa, insurance is to ascertain the broken pieces, and then in a new insurance after exclusion.
6 and the reservoir added lubricant must use within DJB - H1.6 type electric grease filling pump from the mouth is grease filling.
7 and the reservoir in film capacity indicator applies only to use medium for lubricating oil, grease, must change into float type capacity indicator.
8 and electric reducer with two months early from the exhaust plug hole supplementary 3 # mos2 lubricating grease, every four months after supplement.
9, this series of electric lubrication pump for indoor or outdoor installation, in applications use, must adopt preventive measure.
Seven, a loan
1 and mobile devices, electric lubrication pump must be clearly in the contract the hose length and the length of cable, no note with cable 10 meters, hose 3 meters.
2, this series of electric lubrication pump is the following 3 kinds of standards, can form according to different electric control requirements for choice.
No GDK01 type electric monitoring 2.1
There GDK02 type electric monitoring 2.2
GDK03 2.3, which has full automatic control electric control
3, this series of electric lubrication pump for short intervals, have door to working for a long time, please connect work indicated in the contract.
As for spare parts
1 and 10 (deposit insurance pieces in the oil pump mouth screw holes in the lower side),
2, 2 sets of filter |
