Combined vane pump ZYB-50/ZYB-80 has two upper cover structures A & C to choose, suitable for connecting different pipelines. With built-in oil and gas separator and relief valve, this kind of pumps have advantages of low noise, large flow and long lifespan.
Working Process of Vane Pump
When the high-pressure oil output by the vane pump enters the oil-gas separation pipe from the oil outlet of the pump, under the action of the deflector at the inlet of the oil-gas separation pipe, most of the oil advances in a spiral shape along the inner wall of the oil-gas separation pipe. Finally, it flows from the oil outlet of the oil-gas separation pipe to the oil outlet valve. The gas mixed in the oil is less dense than the oil, so it is concentrated in the middle of the official cavity, and finally discharged from the oil-gas separation pipe to the normal pressure cavity. After the oil-gas mixture enters the atmospheric chamber, the gas floats up, discharged into the atmosphere through the exhaust pipe. And the oil is stored in the normal pressure chamber.
When the oil accumulates to a certain amount, the float floats up, driving the connecting rod to open the oil return valve, and the oil flows to the low pressure chamber through the oil return valve. While when the oil level drops to a certain height, the float falls back under the action of gravity, the oil return valve closes the valve, and the oil return function stops.
When the rotor rotates continuously, the vane pump outputs a certain pressure and flow of oil. The size of the oil delivery pressure depends on the pressure adjustment state of the relief valve and the load resistance. And the pressure oil coming out of the vane pump enters the oil-gas separation pipe for oil-gas separation. Part of gas-free oil coming out of the oil-gas separation pipe will return to low-pressure chamber through relief valve. And the other part will enter the flowmeter via the oil outlet valve.
When fuel nozzle is open, the load resistance would be small, and the pressure oil overcomes the spring force of the oil outlet valve and enters flow meter from the oil outlet valve, and the relief valve is closed or slightly opened. When fuel nozzle is closed, the oil pressure rises, then relief valve is completely opened. Next the pressure oil in the high-pressure chamber flows through relief valve to the inlet of vane pump and recirculates. Usually, the pressure and output flow of hydraulic system can change by adjusting the stud of relief valve.

The metering fuel nozzle LLY-25 series is a combination of horizontal screw-wing flow meter and fuel gun. It is a meter instrument used to measure the volume flow rate of liquid (petrol, diesel, engine oil, hydraulic oil, etc.) flowing through the pipeline. In virtue of reliable performance, this metering fuel nozzle LLY-25 is suitable for filling petrol and other light oil products.
Metering fuel nozzle LLY-25 is used for on-farm accounting, both in stationary installations and in ground-based refueling and pumping facilities. It is used as a pistol for refueling in small settlements at gas stations of a local scale.

Working Principle
Having roller pointers for a one-time count of the amount of liquid, the gun with a counter serves to count the amount of fuel that has passed through it. Roller disposable pointer crane LLY has a device for setting the readings to zero. Accounting for the amount of liquid that has passed through the counter gun is based on counting the number of revolutions of the drive screw inside the fuel dispenser gun. The flow of the measured fuel, entering the meter and passing through the volume meter, loses part of the pressure to create a torque that causes the screws to rotate. The measurement of the amount of liquid by a pistol with a counter occurs due to the periodic cutting off of certain volumes of it contained in the cavities between the cylindrical bores of the holder and the screws. This device is a combination of the simplest fuel dispenser gun and fuel meter, the accuracy and performance of which are inferior to industrial designs. Pressing the lever opens the valve, fuel flows through the gun. When the faucet lever is released, the valve closes under the action of a spring, blocking the flow of liquid. The adjusting screw is intended for equipment calibration. The drain pipe of the dispensing gun with a counter is used to direct the liquid into the container when refueling.
