Vane Pump
Fuel dispenser automatic verification system, through the vane type pump magnetostrictive liquid level sensor and the realization of the embedded platinum resistance thermometer liquid level height and standard metal gauge temperature vacume pump automatic data nozzle pump collection, and complete the metal gauge standard capacity value calculation.
a. The rotor of the pump is
rotated clockwise by the motor, and the vanes are rotated together with ring in
the same direction. The rotor and the casing are eccentric with each other.
Because of the eccentricity, the volume enclosed in the rotor, vane and inside
wall of the casing is changed as the rotor rotates, vane type pump and the oil
is moved consequently.
b.
A strainer is installed to the suction to prevent foreign
substances from entering the pump and piping, and a check valve is installed to
prevent the oil in the pump from returning to the tank. c. The oil sent out of
the pump is sent to air separator. Because of the flow guide, the oil is sent
along the casing of the air separator in the method of spiral mode of motion.
The low density gas-oil mixture is sent through the center(Hole, φ4 )of
discharge header to the normal pressure chamber.
d. The separated air is released
through vent-pipe from the top of the atmospheric chamber into the
atmosphere.
e. The oil
discharged through the φ4 hole accumulates in the atmospheric chamber.
If the oil reaches a certain level, the float is floated to open the valve, then
the oil is returned to the suction side.
f. The control valve consists of
main valve and auxiliary valve. The main valve on the discharge side is kept
open by the oil pressure while the oil is nozzle pump being supplied. When the
nozzle is closed , this main valve is closed automatically to prevent the oil in
the hose and flow meter from flowing back. This main valve also holds the oil
pressure in the hose and flow meter while the operation is stopped to protect
the flow meter from being rotated when the oil is supplied next time.
g. When the pressure rises to a
certain value due to change of ambient temperature, the auxiliary valve vane
type pump opens to vacume pump release an abnormal pressure caused by the
thermal expansion of oil.
h. The discharge side of the
casing is equipped with nozzle pump a bypass valve which is used to circulate
the oil through the pump when the nozzle is closed or the oil is supplied at a
low speed. The discharge pressure can be adjusted with a spring.
| Adjustment of set pressure of pump | |
| If the discharging flow rate is too low
because of higher suction head and longer piping, etc., and the discharge
pressure of pump is unstable, the discharge pressure(the nozzle is closed) and
inlet vacuum pressure(the nozzle is kept open) must be inspected. There are
1/4b. When installing or dismantling pressure gauge and vacuum pressure gauge,
stop the pump. The set pressure of vacume pump has been adjusted to 0.18~0.20Mpa
with the nozzle closed when the pump left factory. If the measured pressure does
not according with the set pressure and the adjustment of bypass valve is
needed, please adjust the bypass valve when the pump is not rotated. 1) Loose cap nut. 2)Adjust the set pressure by turning the adjusting bolt: ·Turning clockwise: set pressure heightened. ·Turning counterclockwise: set pressure lowered. 3) After adjusting set pressure, tighten cap nut. 4) Take care not to screw the adjusting bolt excessively to lock valve. If the valve is locked. |
Gear Pump
Gas pumps parts is the energy source of Fuel Dispenser. Censtar pump parts and service, by referring to European and American advanced technology and by adopting international standards of OIMLR117 and OIMLR118, developed GP03 gear type pump and was awarded patents for it.
The pump parts and service can be sucked and delivered through the engagement and disengagement of the gear teeth. See Fig. 2.1.3. When the internal gear is rotated clockwise, the gas pumps parts external gear is rotated together in the same direction. Because of the eccentricity, the volume enclosed between the internal gear and the external gear type pump is changed as the gear rotates, thus making oil to be delivered consequently
Pump parts and service compact structure, easy installation and maintenance, low noise, smooth operation, low fault rate and long service life;Built-in non-return valve, switch valve, relief valve, vacuum valve, gas pumps parts can be more than with oil gun come on at the same time, used for gasoline, kerosene, diesel oil, etc., gear type pump can prevent gas, avoids the gas can't oiling phenomenon.
