1, the whole machine does not produce oil (1) triangle tape is too loose, the pump speed is too low to suck oil.
(1) Adjust or replace the tape

(2) The suction pipe is not tightly sealed and leaks, causing the pump to empty.
(2) Check that the screw in the suction pipe connection is tightened and the gasket is intact.

(3) The oil pump blade is seriously worn, the end face clearance is too large, the vacuum degree is too low to absorb oil.
(3) The blade should be replaced when the length of the end face of the blade is less than the axial length of the rotor.

(4) The separator outlet valve is stuck and cannot be opened.
(4) Open the separator cover and check the oil outlet valve. The movement is flexible and the reset is correct.

(5) The parallel valve of the separator is open, and the lower part of the oil return buoy does not cover the valve hole.
(5) Overhaul the parallel valve to make it flexible up and down, adjust the position of the oil return buoy so that it is flexible from top to bottom, and the lower cone covers the parallel valve hole.

(6) The flow meter stuck (6) In the work, open the oil gun, the flowmeter drive shaft is rotating, the stuck flowmeter should be replaced or repaired

(7) Oil pump rotor loosely fitted with shaft (7) Replace oil pump

(8) Combination pump relief valve stuck (8) Remove relief valve, remove burrs or debris, reload, make valve rotation.

(9) The oil level in the oil storage tank is lower than the double door bottom valve, and the gas exits the oil gun.
(9) Please add oil to the tank

(10) The two oil pumps of the two machines or the double striker share one pipe.
(10) Change the pipeline or add a check valve.

(11) The bottom valve is stuck and cannot be filled with oil. The pump sound is very light and there is no oil in the pump.
(11) Repair bottom valve

(12) The oil level is too low for machine suction and cannot be filled.
(12) Please increase the liquid level.

(13) The solenoid valve cannot be opened.
(13) Replace or repair the solenoid valve

2. Significant reduction in oil

(1) The triangle belt is too loose (1) Tension triangle tape

(2) Plugging of the separator filter (2) Cleaning the filter

(3) Plugging of tank bottom valve (3) Cleaning plug

(4) The lower cone of the return oil buoy of the separator cover the parallel valve hole, but the leakage is too large.
(4) Adjust the buoy

(5) Oil pump wear (5) Precession pump adjustment screw Increase oil pressure but do not exceed 0.3 MPa. If not, replace the oil pump.

3. The noise of the oil pump is large (1) The oil pressure relief valve of the oil relief valve fails (1) Replace the pressure regulating spring

(2) The relief valve seat is too loose with the valve plug or the valve seat is loose with the pump housing.
(2) Replace seat or spool or oil pump

(3) Excessive axial runout at the rotor end (3) Replace the oil pump

(4) The plug of the separator filter or the tank bottom valve is blocked.
4) Clean the filter or foot valve

(5) The wear of the bearing sleeve of the oil pump is too large and the clearance is too large.
(5) Replace bearing sleeve

(6) loose shell installation (6) re-tighten screws or cushion

4. Accuracy exceeds ±0.30%, and cannot be adjusted (1) Wear of the flowmeter connection (1) Replacement of the edge contact block

(2) Wear of piston liner (2) Change flowmeter

(3) Damage to the inner seal ring (3) Replace the seal ring

(4) bakelite wheel wear (4) replacement bakelite wheel

(5) Adjust the rod to wear or get stuck (5) Change the lever

5. Separator exhaust pipe injection (1) Parallel valve block (1) Clear parallel valve

(2) Return float or ball float break (2) Replace float

(3) The oil float can't float (3) Adjust the float

(4) The leakage of the inner wall of the body shell causes the pressure chamber to communicate with the high pressure chamber (4) Replace the body shell or separator

6. There are too many oil bubbles and the accuracy is poor (oil shortage)
(1) The triangle belt is too loose (1) Tension triangle tape

(2) Leakage in the inlet line (2) Check the connection and sealing of the inlet line

(3) Leakage in the separator's low pressure chamber (3) Check if the gasket of the low pressure chamber is intact and whether the gasket cover is compacted.

(4) The outlet valve of the separator is blocked (4) The cleaning outlet valve is kept open

(5) The exhaust pipe of the separator is blocked (5) The exhaust pipe is cleaned to keep it open

(6) Blockage of the filter in the combination pump (6) Cleaning the filter

(7) Tank bottom valve plug (7) Wash bottom valve

(8) Pump failure (8) Repair the pump vane or relief valve.

7. The oil gun is out of the oil, but no display is shown (1) The connection between the flowmeter rotating shaft and the sensor or transmission elbow is detached and cut off.
(1) Reconnect
