Flip-flop transition is greatly shortened, and has saved driver's cab turnover Maintenance Demand Time, improves work efficiency, electrodynamic pump 1 and manual pump 2
Between connected by oil pipe 3, oil pipe 3 uses stainless steel tube to make, easy-formation, is suitable for making difform pipeline needs, resistance to
Hou Xingqiang, rust-preventing characteristic is strong, and intensity is high, and fatigue durability is high, and electrodynamic pump 1 is provided with the motor 4 being connected with electrodynamic pump 1, and motor uses
24V voltage, permanent magnet DC motor, noise is little, water proof and dust proof, rotating speed high-band overheat protective function, and power is big, and efficiency is high, product
Moderate cost, electrodynamic pump 1 is provided with the first check valve 5 being connected with electrodynamic pump 1, is provided with built-in second unidirectional in manual pump 2
Valve 6, manual pump 2 is provided with the 3rd check valve 14 being connected with manual pump 2；It is additionally provided with on electrodynamic pump 1 and continuing that electrodynamic pump 1 is connected
Electrical equipment 7, relay 7 is electromagnetic relay, highly sensitive and operating frequency is high, and relay 7 is connected to socket 8 and switch 9,
Switch 9 is toggle switch, dustproof and waterproof, and fatigue durability is high；Electrodynamic pump 1 is provided with the overflow valve 10 in parallel with electrodynamic pump 1, manually
Pump 2 is provided with the overflow valve 10 being connected with manual pump 2, and when system pressure is excessive, electrodynamic pump overflow valve can automatically open up earial drainage,
Thus reduce system pressure, it is to avoid the explosion of oil pipe or the damage of pump, it is ensured that the safety in work process.
Being provided with fuel tank in manual pump 2, electrodynamic pump 1 is connected with fuel tank, from manual pump 2 when electrodynamic pump 1 works by oil pipe 3
Pressure oil needed for fuel tank suction work, electrodynamic pump 1 no longer sets up fuel tank, greatly reduces the volume and weight of pump, manual pump 2 He
Electrodynamic pump 1 is connected by bite type respectively with oil pipe 3, and oil pipe uses stainless steel tube, reduces the probability that pipeline gets rusty, significantly
Improve the weatherability of product, the adaptability of environment, the weather conditions such as including damp and hot soda acid, and bite type connection is reliable, by force
