Abstract
The utility model belongs to oil transportation pump technical field, especially a kind of hot wind lubricating oil pump.The oil pump includes pump case and pump cover, coil block is arranged with outside pump case, oil inlet is set on pump cover, and inlet nozzle is connected by oil inlet with pump case inner cavity, intracavitary sets dynamic iron core with pump cover contact jaw in pump case, and dynamic iron core sets rubber seal plug with oil inlet contact jaw, the other end is connected with piston rod one end, the other end of piston rod is mobilizable to be placed in one end of copper sheathing, and compression spring is set between copper sheathing and dynamic iron core, and the other end of copper sheathing is connected with oil outlet connector.The utility model is since electromagnetic pump is using electromagnetic principle, and the displacement of dynamic iron core is also less, therefore the abrasion generated is also less, lengthens the service life of oil pump, the cleannes of fuel oil are also effectively promoted.Electromagnetic pump is simple in structure, and volume is smaller with respect to other oil pumps, and production cost is low.
Description
Technical field
The utility model belongs to oil transportation pump technical field, especially a kind of hot wind lubricating oil pump.
Background technology
Hot wind lubricating oil pump is mounted in fuel tank, is immersed in fuel oil, and effect is to be pressurized gasoline, and be continuously pumped into
Oil supply pipe.Electric fuel punp in the market provides dynamic generally all using the combination of permanent magnet motor and commutator come oil fuel feed pump
Power, since commutator is easy to wear, the service life that this results in fuel pump is shorter, while the dust worn is directly entered in fuel oil,
Also the cleannes of fuel oil are shone into influence.Electric fuel oil pump configuration in the market is more complicated, and parts are more, corresponding cost
Larger, volume is also relatively large.
Invention content
The purpose of this utility model is the deficiencies in the prior art part to be solved, and abrasion can be reduced, extend by providing one kind
The electromagnetic pump of service life.
The technical solution that the utility model is taken to achieve the above object is：
A kind of hot wind lubricating oil pump, the oil pump include pump case and pump cover, and the pump case is fixedly connected with pump cover, the pump
Coil block is arranged with outside shell, oil inlet is set on the pump cover, and inlet nozzle passes through the oil inlet and pump case inner cavity
It is connected, intracavitary sets dynamic iron core with pump cover contact jaw in the pump case, and the dynamic iron core is set with oil inlet contact jaw
Rubber seal plug, the other end are connected with piston rod one end, and the other end of the piston rod is mobilizable to be placed in copper sheathing
In one end, and compression spring is set, the other end and the oil outlet connector phase of the copper sheathing between the copper sheathing and dynamic iron core
Connection, spray chamber room there are one tools between the end of the copper sheathing inner piston rod and oil outlet connector, and on the spray chamber room
It is provided with the fuel feed hole being connected with pump case inner cavity.
As a further improvement, setting check-valves in the oil outlet connector.
As a further improvement, the check-valves includes oil outlet valve spring and steel ball.
As a further improvement, filter screen is set between the inlet nozzle and pump cover.
As a further improvement, setting slot in the dynamic iron core, the piston rod is plugged in slot
Compared to the prior art the utility model has the characteristics that and advantageous effect：
1st, since electromagnetic pump is using electromagnetic principle, the displacement of dynamic iron core is also less, therefore the abrasion generated is also less, makes
The service life of oil pump lengthens, and the cleannes of fuel oil are also effectively promoted.
2nd, electromagnetic pump is simple in structure, and volume is smaller with respect to other oil pumps, and production cost is low.
