1. Overview

This type of manual lubrication pump is a small-sized device that manually pulls the handle to discharge grease.Single line lubrication pump, can be installed directly on the wall panel or frame of the machine. Directly connected to the single-line distributor to form a single-line manual centralized lubrication system.

It is suitable for single-machine small equipment with low lubrication frequency (generally the oiling interval is more than 4 hours), the length of the piping (D N15) does not exceed 50 meters, and the lubrication points do not exceed 100 points. It is used as a single-line centralized lubrication supply to transport grease. device.

2. Technical parameters

3. Action principle

The manual lubrication pump manually swings the handle, and the gear drives the rack piston to reciprocate to supply oil to the outside. When the piston is at the limit position as shown in the figure, the grease is sucked in through the suction port and fills the right cavity of the piston. When the piston moves to the right, the sucked grease pushes open the one-way valve under the action of oil pressure and is sent to the discharge port. discharge outward. When the amount of oil returned to the oil return indicator from a metering oil port of the main distributor in the system reaches 3.2mL, the indicator rod is fully extended, proving that all lubrication points in the system have received the required amount of lubricating oil. At this time, stop Operate the handle and press the indicator rod inward to prepare for the next cycle. The grease in the indicator returns to the oil storage barrel through the one-way valve.

4. Operation method

1. Push the indicating rod of the oil return indicator.

2. The swing handle moves forward and backward, and the pointer of the pressure gauge fluctuates, which proves that the system distributor is performing oiling action.

3. The indicator rod of the oil return indicator is fully extended, proving that the system distributor has completed an oil lubrication cycle.

4. Push the indicating rod of the oil return indicator to prepare for the next cycle.

6. Instructions for use

1. The manual lubrication pump should be installed vertically, and there should be space above and around the pump for the indicator rod to rise and for grease replenishment. When it needs to be installed outdoors or in harsh environments, the pump should be placed in a protective cover.

2. When there is no grease in the oil reservoir, do not operate the handle. Grease should be replenished in time when the oil level reaches the lower level.

3. To replenish grease into the oil reservoir, you must use a manual or electric grease pump to fill from the grease port.

4. The safety valve has been adjusted to the nominal pressure at the factory and is not allowed to be adjusted at will without any reason.

5. The function of the oil return indicator on the pump is that the operator can know the oil return indicator by observing the movement stroke of the indicator piston indicator rod.Process lubricationThe oil supply status of the system. When using, first calculate the amount of oil required for each lubrication part, configure the distributor, and connect an additional oil outlet on the main distributor to the oil return port of the manual lubrication pump to return the grease to the indicated level. In the instrument, if the cumulative amount of returned oil reaches 3.28ml, the piston indicator rod of the indicator will all extend, indicating that each lubrication point has completed a cycle of oil supply as required. The oil supply should be stopped and the indication of the oil return indicator should be stopped. Rod advances.
