1. Conditions of use

The manual lubricating pump is a small lubricating pump operated by a manipulator to move the lubricant. It can be directly installed on the wall or frame of the machine. The basic type can be combined with a single-line distributor to form a manual single-line centralized lubrication system; the basic type is equipped with a reversing valve and a two-line distributor to form a manual two-line terminal centralized lubrication system.

The pump is suitable for single-unit small equipment with low lubrication frequency (usually the oil supply interval is more than 8 hours), the length of the piping D N10 does not exceed 50 meters, and the lubrication point does not exceed 40 points. .

2、Technical Parameters

The medium used is a grease (NLGI 0 # ~ 2 #) with a penetration of not less than 265 (25 ° C, 150g) and 1 / 10mm, and a lubricant with a viscosity greater than N68. The applicable ambient temperature is -10 ° C to 40 ° C

5. working principle

The manual lubricating pump manually pulls the handle, and the gear piston 2 drives the gear piston 2 to reciprocate to realize the grease supply. When the piston is at the extreme position on the right end of the figure, the volume of the left end oil chamber increases to form a vacuum, so the lubricant in the oil reservoir is sucked into the left end oil chamber of the piston from the oil suction port under the action of the spring and the piston plate. When the piston moves to the left, the sucked lubricant is pressed into the channel Ⅰ and pushes the slide valve 4 to the right end limit position, and the check valve 5 is opened to discharge from the oil outlet. At this time, the volume of the oil chamber at the right end of the piston gradually increases. The lubricant is sucked in. When the piston moves back to the right, the oil chamber filled with lubricant gradually becomes smaller, squeeze the lubricant into the channel Ⅱ, push the slide valve 4 to move to the left, and open the check valve 5 from the oil outlet. The pump is equipped with a reversing valve at the bottom of the pump, and the reversing handle can be moved to the left and right extreme positions to realize dual-line feeding.

6.Operation method

Single line type:

1. Push the rod of the oil return indicator.

2. The swing handle moves back and forth, and the pressure gauge pointer fluctuates, which proves that the system distributor is supplying oil.

3. All the indicating rods of the oil return indicator pop out, proving that the system distributor has completed an oil supply cycle.

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

Double line type:

1. Turn the handle of the reversing valve to the left position to supply oil to main line I and unload main line II.

2. The handle of the pump is moved back and forth, and the pointer of the pressure gauge fluctuates, proving that the system distributor is supplying oil.

3. The pressure gauge on the pump indicates that the pressure value rises and remains stable, which proves that the system distributor has completed one cycle of operation.

4. Operate the handle of the reversing valve to the right position, the main line II supplies oil, and the main line I unloads. Operate according to 2 and 3 to complete a cycle of the system.

5. Reverse the reversing valve, remove the pressure in pipeline II, and prepare for the next cycle.

7.instructions for use

1. The manual lubricating pump should be installed vertically, and there should be space above the pump and around the indicator rod for ascending and replenishing operations. When installing outdoors or in a harsh environment, the pump should be placed in a protective cover.

2. When there is no lubricant in the oil storage tank, do not operate the handle.

3. To fill grease into the oil reservoir, you must use a dedicated manual or electric refueling pump to fill it from the filler; the lubricating oil is added from the top of the oil reservoir.

4. The operating pressure must not exceed the nominal pressure of the pump.

5. The safety insurance film is not allowed to be overlapped, and other materials are not allowed to substitute.

6. The function of the oil return indicator on the single-line pump is that the operator can know the oil supply and lubrication status of the lubrication system by observing the movement stroke of the indicator piston. When using, first calculate the required oil supply for each lubricating part of the process, configure the distributor, and connect an extra oil outlet on the main distributor to the oil return port of the manual lubrication pump to return the lubricant Into the indicator, if the total amount of returned oil reaches 3.28ml, the piston indicator rod of the indicator is fully extended, indicating that each lubrication point has completed a cycle of oil supply as required, the oil supply should be stopped and the oil return indicator The indicator lever advances.
