The invention cancels two one-way valve structures of a plunger pump in the market, adopts a straight slot way to absorb oil, and when the inner and outer straight slots are in a communicated state, the grease supplementing machine absorbs oil, and when the straight slots are in a completely closed state, the grease supplementing machine oil. The oil absorption speed is high, the oil absorption resistance is low, the oil absorption device can stably operate even in a low-temperature environment, a certain gap is reserved between the outer shell cylinder 12 and the inner shell cylinder 13, the inner shell cylinder 13 is facilitated to rotate, a certain amount of lubricating grease is filled in the gap to play a role in sealing, and two 8 sealing rings are added at the tail end of the tail rod of the 6 ejector rod and the front end of the 18 piston and are used for sealing leakage of high-pressure lubricating grease.
The present invention further includes:
1. The invention adopts the relative rotation of the inner and outer cylinders to realize the opening and closing of the oil absorption straight slot, and the diameter of the oil absorption straight slot is large enough when the inner and outer oil absorption straight slot is opened, the oil resistance is extremely small, and the lubricating grease can be smoothly inhaled even in the low temperature environment when the flowability of the lubricating grease is poor.
2. The driving cam and the deflector rod are integrally designed, so that the correct matching of the linear motion and the rotary motion is realized.
3. The rotary opening and closing of the oil suction port does not consume the stroke of the plunger, and the rotary opening and closing is completed when the motor load is minimum, so that the requirement on the power of a power supply is effectively reduced.
Similar products and functions as described above, which are extensions of the present invention, are intended to be protected.
