Abstract
The invention discloses an oil barrel pump sealing pumping rod device. The oil barrel pump sealing pumping rod device comprises a shell, a bolt is mounted at the front end of the shell, a pumping rod is mounted at the rear end of the shell, the bolt is provided with a first through hole axially, and the pumping rod penetrates the first through hole of the bolt. The bolt of the oil barrel pump sealing pumping rod device is connected with and fixes the pumping rod, and the pumping rod can be prevented from separating from the shell during backward running; a leather sheath of the pumping rod has a sealing function and can seal the oil when the pumping rod moves back and forth.
Description
Technical field
The present invention relates to the accessory field of pump, especially a kind of pump for oil tank pumping rod device.
Background technique
Pump for oil tank should according to technological process, plumbing requirement, takes in from liquid-conveying amount, Unit head, liquid property, line arrangement and operation operating condition five aspects.Pump for oil tank is classified: hand pump for oil tank, electric barrel pump and pneumatic pump for oil tank.Regardless of the pump for oil tank for which kind of type, the structural feature of pumping rod device wherein directly has influence on their normal operation.But structurally there is certain deficiency in existing pump for oil tank, the stationarity of the pumping rod in existing pump for oil tank is poor, usually just there is the phenomenon come off in the course of the work, the sealing effect of pump for oil tank is poor simultaneously, pump for oil tank Chang Yinwei blow-by and cause pumping rod normally to run, has had a strong impact on the working efficiency of pump for oil tank.
Summary of the invention
The present invention is in order to solve the problem proposed in above-mentioned background technology, and provide a kind of pump for oil tank to seal pumping rod device, good airproof performance, pumping rod is difficult drop-off in running.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pump for oil tank sealing pumping rod device, comprise housing, the front end of housing is provided with bolt, and the rear end of housing is provided with pumping rod, the axial direction of bolt offers the first through hole, pumping rod is through the first through hole of bolt.
Further restriction: the rear end of pumping rod is installed with the leather sheath for sealing.
Further restriction: the axial direction of pumping rod offers the second through hole, the sidewall of the front end of pumping rod offers tap hole.
Beneficial effect of the present invention: this pump for oil tank sealing pumping rod device, bolt plays and connects and the effect of fixing pumping rod, can prevent pumping rod from the process run backward, departing from housing; Leather sheath in pumping rod plays the effect of sealing, and when pumping rod seesaws in the housing, leather sheath just serves oil sealing effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of pump for oil tank sealing pumping rod device, comprise housing 1, the front end of housing 1 is provided with bolt 2, and the rear end of housing 1 is provided with pumping rod 3, the axial direction of bolt 2 offers the first through hole 4, and pumping rod 3 is through the first through hole 4 of bolt 2; The rear end of pumping rod 3 is installed with the leather sheath 5 for sealing; The axial direction of pumping rod 3 offers the second through hole 6, the sidewall of the front end of pumping rod offers tap hole 7.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
