JB-70-type hand electric dual metering pumps

■ JB-70-type hand, dual electric metering pumps Product Overview: JB-70-type hand, dual electric metering pumps suitable for small and medium sized oil around the main plus, gas stations, agricultural stations, supply and marketing cooperatives, factories and mines the fleet of vehicles, ships and other units sucking all kinds of oil, such as gasoline, diesel, kerosene, oil, food oil. Compact, reliable, stable performance, easy to move, etc., and fitted with explosion-proof motor with 25 mm flow meter, when electric power can refuel, when there is no power to hand refueling, accurate, no zeroing means. ■ JB-70-type hand, dual electric metering pumps Features and Uses: JB-70-type hand, dual electric metering pumps for the relief valve means within the blade, fill up when the tank material, to close When the oil gun, vane pump can continue to work, when the hydraulic pump exceeds the rated pressure relief valve that is, from automatism, the oil back into the oil tank on their own or in the tank and so on. ■ JB-70-type hand, dual electric metering pumps Technical parameters: 1, Model: Vertical dual-use metering electric pump 2, the permissible suction lift: ≤4-5m 3, the maximum working pressure: 0.25MPa 4, flow range : 25-60L / min maximum flow: 60-805, predetermined flow rate range error: ± 2% (级 2) ± 1% (1 level) 6, the inlet nominal diameter: φ25mm 7, Motor: Three-phase asynchronous explosion Motor 0.8KW 8, the motor supply voltage: 380V 50HZ 9.1, flowmeter LXYL-25 type rotor flow meter (indication error of ± 2%) 9.2, the flowmeter: LY-25-type Lo Wing meter (indication error of ± 1% ) 10, Transmission: V-belt pulleys V-belt drive A type 1168mm 11, Dimensions: 51X41X54 12, machine weight: 55KG ■ JB-70-type hand, dual electric metering pumps structure description and working principle: The explosion-proof switch 1 Turn the knob to pass, sign off "on" position, the explosion-proof motor through the pulley 2 4 6 drive vane pump working oil from the oil tank (or barrel), the filter 12 through the tubing 11, inlet vane pump hole is sucked into the pump chamber vane. After the hole vane pump, oil is pressed into the meter 8 automatic counting measure, and through the tubing 10 into the oil gun, when the oil gun handle clenched, oil is automatically injected into the vessel effluent, release handle, stop the oil outflow. When the oil gun rubber closed, the motor is still driven vane pump, vane pump oil pressure inside will rise followed to prevent mechanical damage, once the oil pressure exceeds the rated pressure relief valve in the pump work automatically, the pump Oil chamber through the inlet port self-vane pump inlet pipe back into the oil reservoir (or tank) inside.
