Abstract
The utility model discloses a direct current motor inflation pump comprising a motor which consists of a magnetic shoe, a carbon brush, a motor screw rod and a rotor; the carbon brush is arranged on a carbon brush seat through a bearing; the rotor is connected with a piston connecting rod through an eccentric wheel and the bearing; a cylinder sleeve is sleeved outside the piston connecting rod; the piston connecting rod and the cylinder sleeve are arranged in a crankcase; a box cover is arranged outside the crankcase; a cylinder head is arranged on the crankcase through an O-shaped ring, screw rods and an air piece; an air pipe and an air centrifuge are arranged and connected on the cylinder head through the screw rods; a motor outer shell, a motor front-end cover and a motor rear-end cover are arranged outside the motor; and the direct current motor inflation pump has the beneficial effects that: significant practical value is realized, 150LPM airflow can be generated only by a 12V direct current power supply, the air displacement is stable, the continuous working time is long, the radiating performance is good, the service life of equipment is long, the performance is stale, and gaps of products in pneumatic suspension equipment and other fields are made up.
Description
Technical field
The utility model relates to a kind of gas-filled pump, particularly a kind of direct current generator gas-filled pump.
Background technique
There is defective in the majority in existing gas-filled pump: existing gas-filled pump is mainly used in automobile tire, motorboat, inflatable toys or the like, but in fields such as big flow inflation of needs such as automobile hanging and function admirables very big blank is arranged still.Automobile suspension system all has higher requirements in throughput, continuous firing duration, working life or the like to charger.
The model utility content
The utility model technical problem to be solved is the deficiency to existing technology, and a kind of new DC motor gas-filled pump is provided.
To achieve these goals, the measure taked of the utility model:
A kind of direct current generator gas-filled pump comprises the motor that is made up of magnetic shoe, carbon brush, motor screw and rotor, and carbon brush passes through Bearing Installation on carbon brush holder; Described rotor is connected with piston rod through eccentric wheel and bearing; Piston rod is with cylinder liner outward, and piston rod and cylinder liner are installed in the crankcase, and crankcase is equipped with case lid outward; Be connected with cylinder head through O type circle, screw rod and the installation of atmosphere sheet on the crankcase, be connected with tracheae and air centrifuge through the screw rod installation on the cylinder head;
Described motor is equipped with motor housing, motor front cover and back end cover for motor outward;
Described motor front cover and motor rear end cover through screw the Rubber foot rivet are installed;
Described cylinder liner is equipped with heat dissipating housing outward;
Silicagel pad is installed between described cylinder head and the atmosphere sheet sends out sheet, install on the piston rod and be connected with piston ring and retainer ring with turnover gas.
The beneficial effect of the utility model: have outstanding use value, only use the 12V DC electrical source promptly can produce the throughput of 150LPM, continuous working period is long; Perfect heat-dissipating; Life of equipment is long, and stable performance has remedied the blank at field products such as pneumatic suspension equipments.
