Disclosure of Invention

The utility model aims at providing a novel electric pump through adding oil pipe, solves and refuels the inconvenient problem of operation.

The purpose of the utility model is realized like this: the utility model provides a novel electric pump, includes the oil tank, installs the motor on the oil tank, be provided with the plunger pump that is connected with the motor in the oil tank, install the oil pipe rather than the intercommunication on the oil tank, install the upper cover on the oil pipe, cover on and seted up the exhaust hole.

Preferably, the upper end of the oil filling pipe is provided with an oil filling port, and the oil filling pipe is internally provided with a cavity communicated with the oil tank.

Preferably, the oil filling pipe is provided with a joint, the joint is provided with the upper cover in a rotating mode, and the periphery of the upper cover is formed with an anti-slip strip.

Preferably, the oil outlet end of the plunger pump is connected with a valve body through an iron oil pipe, and the oil inlet end of the plunger pump is connected with the valve body through an iron oil pipe.

Preferably, a hydraulic gauge for displaying pressure is mounted on the valve body.

Preferably, the oil filling pipe is in threaded connection with the oil tank, and a sealing ring is abutted between the oil filling pipe and the upper end face of the oil tank.

Compared with the prior art, the utility model outstanding and profitable technological effect is:

the utility model discloses an add the oil pipe and can refuel in the oil tank, compare among the prior art need dismantle the back with the screw, just can add the oil operation through the tank filler sleeve, this operation is more convenient, and add and install the upper cover on the oil pipe, because it is higher to add the oil pipe, and there is the upper cover to do and block, consequently in the transportation, can be used for preventing inside fluid spill, can not cause the oil leak, in the prior art, exhaust through the check valve that sets up, the device has and rocks in the transportation, therefore can the oil leak, through having seted up the exhaust hole on the upper cover, make unnecessary gas in the oil tank can discharge through the exhaust hole.

Detailed Description

The following describes the present invention in further detail with reference to the accompanying fig. 1-3.

A novel electric pump.

Referring to fig. 1 and 2, including oil tank 1, install motor 3 on the oil tank 1, be provided with the plunger pump 2 that is connected with motor 3 in the oil tank 1, the motor drives the plunger pump operation to carry out the pressure boost with the fluid in the oil tank 1, install the oil filler pipe 4 rather than the intercommunication on the oil tank 1, can refuel in the oil tank 1 through oil filler pipe 4, and convenient operation, and need dismantle the back with the screw among the prior art, just can refuel the operation through the tank filler hole, the operation is inconvenient, it is useless to add oil filler pipe 4 before promptly, make through increasing oil filler pipe 4 and refuel convenient operation, install upper cover 5 on oil filler pipe 4, because the height of oil filler pipe 4 is higher, and there is upper cover 5 to stop, consequently, in the transportation, can be used for preventing inside fluid spill, can not cause the oil leak. In the prior art, the oil tank is exhausted through the arranged one-way valve, the device shakes during transportation, oil leakage is possible, and the exhaust hole 6 is formed in the upper cover 5, so that redundant gas in the oil tank can be exhausted through the exhaust hole 6.

Looking specifically at fig. 3, oiling mouth 7 has been seted up to the upper end of filling tube 4, set up the cavity that is linked together with oil tank 1 in filling tube 4, and need not to change the structure of oil tank 1 inside, the repacking is convenient, through to oiling mouth 7 oiling, fluid can flow into in the oil tank 1 through the cavity.
