Chamber is in communication with the outside, and then Plunger pump body is in communication with the outside, to guarantee the temperature inside lubricating cup 1, inside Plunger pump body
Degree and pressure and the external world reach balance.
In refueling process, as oil gradually flows into Plunger pump body, oily liquid level position can be reduced in 1 inner cavity of lubricating cup,
Cause spare space to become larger, pressure reduce, be likely at this time due to pressure is too small and Plunger pump body can not be flowed by oil occur
The case where.And at least one spiracle 201 being axially distributed is arranged in the present embodiment on oil cup cap 2 can guarantee the flat of pressure
The case where weighing, avoiding oil that from can not flowing into Plunger pump body, ensure that going on smoothly for refueling process.
Optionally, equally distributed multiple spiracles 201 are set on oil cup cap 2, guarantee the uniform of temperature and pressure.Separately
Outside, the oiling speed setting that the quantity of at least one spiracle 201 can according to need, such as 6 spiracles can be set
201 or 10 spiracles 201.
Optionally, at least one spiracle 201 is set on the outer wall of internal screw thread, and the height of each spiracle 201 with
The height of the internal screw thread of oil cup cap 2 is equal.There are spaces above internal screw thread for oil cup cap 2, i.e., obstructed top on internal screw thread makes at least
One spiracle 201 is connected to the space, and the space and the inner cavity of lubricating cup 1 form a connected region.
Then outside air by the lower part of at least one spiracle 201 enter inside oil cup cap 2 there are spare space, then
It is entered in 1 inner cavity of lubricating cup by spare space, the air communication with 1 inner cavity of lubricating cup ensure that 1 inner cavity of lubricating cup and plunger pump
Intracorporal pressure and extraneous balance.
Optionally, the diameter of each spiracle 201 is less than the outer wall thickness of internal screw thread.
Device provided by the utility model, by being provided with spiracle 201 on oil cup cap 2, ensure that 1 inner cavity of lubricating cup with
Extraneous connection, and then realize that the temperature and pressure of inner cavity and Plunger pump body and the external world reach balance, it avoids due to lubricating cup 1
Pressure change inside inner cavity and Plunger pump body and the case where cause oil that can not flow into Plunger pump body.
1 and Fig. 2 is illustrated the refueling process of plunger pump refueling device provided by the utility model with reference to the accompanying drawing:
The oil outlet 3 of lubricating cup 1 is connect by step 1 with Plunger pump body, is infused by the top of lubricating cup 1 into 1 inner cavity of lubricating cup
Enter oil.
Wherein, the oil filler that oil outlet 3 can be arranged with Plunger pump body top is threadedly coupled.Oil cup cap 2 can also be with
The top of lubricating cup 1 is threadedly coupled.
Step 2, lubricating cup 1 inner cavity in be provided with combination filter screen 4 and shadoof 5, the oil of injection lubricating cup 1 can first pass through first
Through-hole on pressing plate 401 enters filter screen 402, after the filtering of filter screen 402, then by the through-hole in the second pressing plate 403 to
Under flow to oil outlet 3, entered in Plunger pump body by oil outlet 3.
Step 3, when filling oil in the inner cavity of lubricating cup 1, oil cup cap 2 is connect with 1 top of lubricating cup, to the inner cavity of lubricating cup 1
It is closed.
Step 4, as the oil stream in 1 inner cavity of lubricating cup is to Plunger pump body, can cause to press because of the reduction of oil in inner cavity
Power becomes smaller, and outside air is entered in the inner cavity of lubricating cup 1 by the spiracle 201 being arranged on oil cup cap 2 at this time, thus equilibrium oil
The pressure of cup 1 inner cavity and Plunger pump body, makes oil continue to flow to Plunger pump body, finally makes oil note all in 1 inner cavity of lubricating cup
Enter into Plunger pump body, realizes the purpose smoothly refueled.
After a period of use, combination filter screen 4 can exist many plunger pump refueling device because of prolonged filtering
Impurity, operator need to clean it or replace.1 and Fig. 2 is to plunger provided by the utility model with reference to the accompanying drawing
The combination filter screen replacement or cleaning process for pumping refueling device are illustrated:
Step 1 opens the oil cup cap 2 on lubricating cup 1.
Wherein, lubricating cup 1 can be threadedly coupled with oil cup cap 2, and 2 top of oil cup cap is provided with twill spiral surface, guarantees lubricating cup 2
There is biggish frictional force on outer surface, operator is facilitated to unscrew oil cup cap 2.
Step 2, lifting 5 upper end of shadoof, combination filter screen 4 can be suggested 1 inner cavity of lubricating cup with shadoof 5.
Step 3, the second nut 503 of rotation are screwed off shadoof 5, and combination filter screen 4 can also lose fixation, from shadoof 5
It separates, the first pressing plate 401 and the second pressing plate 403 can be cleaned at this time, filter screen 402 is replaced, thus
The cleaning replacement process of complete pair-wise combination filter screen 4.
The above is merely for convenience of it will be understood by those skilled in the art that the technical solution of the utility model, not to
Limit the utility model.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
