Qidong Dele is the first choice for SRB-J/L series manual lubrication pumps

Series manual lubrication pump (,)
1. Overview
This machine is a small lubrication pump that can be directly installed on the wall plate or frame of the machine, and the handle is pulled manually , discharge grease, and can be combined with a double-line distributor to form a manual centralized lubrication system to supply quantitative grease to each lubrication point of the machine. It is suitable for low frequency (generally more than 1 hour of lubrication interval). The length of the piping ( ) does not exceed one meter and the lubrication point It is used as a device for centralized lubrication and grease supply on small single-machine equipment that does not exceed the point.

5. Action description
The grease supply of the manual lubrication pump is realized by manually swinging the handle and driving the rack-mounted oil supply plunger to reciprocate through the pinion. When the plunger When the plug is at the extreme position of the right end, the oil pressure in the right end chamber is completed, and the oil suction in the left end chamber is completed. When the handle is swung and the plunger moves to the left, the suction port of the left chamber is closed first, and the grease is squeezed to push open the one-way valve and reverse the direction. The valve flow channel enters the main oil supply line II and is discharged. At this time, the volume of the right chamber of the plunger increases to form a vacuum, and the degree of vacuum gradually increases. When the plunger moves to the extreme position of the left end, the suction port of the right chamber opens, and in the atmosphere Under the action, the grease is sucked in, and the above action is reversed. The grease pushes up the check valve and enters the main oil supply line through the reversing valve flow channel and is discharged. The reversal in the oil supply process is achieved by the reversing of the reversing valve. .When the reversing valve handle is pushed forward, the grease is discharged from the main pipe. When the reversing valve handle is pulled out, the grease is discharged from the main pipe.


6. Operation method
Push the reversing valve hand button to the extreme position and supply oil from the oil supply main pipe.
The swing handle moves forward and backward, and the pointer of the pressure gauge fluctuates, which proves that the series distributor is supplying oil.
The pressure value indicated by the pressure gauge on the pump remains stable, proving that all actions of the system distributor are completed.
, Pull out the reversing valve hand button to the extreme position, supply oil to the oil supply main pipe, and press and to operate.
Remove the pipeline pressure, switch to the oil supply main pipe, prepare for the next working cycle, and move the handle to the vertical position.

7. Instructions for use
The manual lubrication pump should be installed vertically. There should be space above and around the pump for the indicator rod to rise and for grease refilling. It needs to be installed outdoors or in harsh environments. During installation, the pump should be placed in a protective cover.
When there is no grease in the oil reservoir, the handle is not allowed to be operated, and the oil level should be replenished in time.
To add grease to the oil reservoir, a special manual or electric refueling pump must be used to fill from the refueling port.
The operating pressure of the pump must not exceed the nominal pressure of the pump.
The filter screen of the pump filling port should be checked and cleaned regularly.
Fault phenomenon
Cause of the fault
Troubleshooting method

The output pressure of the pump cannot rise
The force gauge is damaged
Ingress into the oiler and piping Air
The fuse is broken
It has been used for a long time, and the plunger and sleeve are excessively worn

Replace the pressure gauge
Open the exhaust valve to exhaust
Replace the fuse Tablet
Replace parts

The output pressure of the pump rises sharply
The reversing direction of the directional valve is not in place
The road is blocked
The orchestrator operates poorly
Directional position Valve
Check the pipeline
Check the action of the distributor
