Description
Technical field
The utility model belongs to pump technology field, relates to a kind of pump cover.
Background technique
Motor can be entered into prevent the water being positioned at pump chamber, mechanical seal is provided with between motor and pump cover, in order to the effect making mechanical seal reach Cooling and Lubricator, between motor connecting base and oil cylinder cover, be formed with grease chamber, mechanical seal is soaked in the fluid in this grease chamber.During submersible pump work, driven by motor rotor and mechanical seal rotate, the fluid in grease chamber is driven to rotate together, no matter take how sealing means, gap is there is between rotating shaft and mechanical seal, because the lubricant oil being positioned at grease chamber is more, the lubricant oil being positioned at grease chamber under pressure enters into pump chamber through after mechanical seal, affects water quality.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes the pump cover of a kind of reasonable in design, high lubricating effect.
The purpose of this utility model realizes by following technical proposal:
This pump cover, comprise body, described body is provided with the axis hole passed for rotating shaft and the shoe cream room being located at axis hole periphery, described shoe cream room is communicated with described axis hole by oil-through hole, it is characterized in that, one end place that described oil-through hole is positioned at shoe cream room is provided with rubber plug, being provided with for guiding plug along the guide structure of the axial motion of oil-through hole, being also provided with the driving structure for driving plug to move along guide structure in described shoe cream room in described shoe cream room.
In above-mentioned pump cover, described guide structure comprises the guide holder coaxially arranged with oil-through hole and the guide rod be arranged in guide holder, above-mentioned plug is located at the outer end of this guide rod, also be provided with the spring that its one end acts on guide rod the inner in described guide holder, the other end of described spring acts on guide holder.
In above-mentioned pump cover, described driving structure comprises the driveshaft being articulated with shoe cream room sidewall, and one end of this driveshaft acts on above-mentioned guide rod, and the outer end of this driveshaft extend out to the outside of described shoe cream room.
In above-mentioned pump cover, the sidewall of described shoe cream room has the articulated section for support drive bar.
In above-mentioned pump cover, the sidepiece of described guide rod has groove, and the inner of above-mentioned driveshaft is inserted in this groove.
When needing charging-up lubricant oil in axis hole, pulling driveshaft with hand, making guide rod to guide holder internal motion, plug is driven to depart from oil-through hole, now spring is in compressive state, and oil-through hole is communicated with shoe cream room and axis hole, and the lubricant oil being positioned at shoe cream room enters into axis hole countershaft etc. and lubricates.After lubrication, unclamp driveshaft, spring reset, guide rod is driven to move to oil-through hole direction, block oil-through hole at the effect lower end cap of spring force, the lubricant oil being positioned at shoe cream room cannot enter into axis hole, owing to not having unnecessary lubricant oil in axis hole, therefore lubricant oil can not enter in pump chamber and motor, effectively can extend the working life of water pump.
Compared with prior art, this pump cover has the following advantages:
Its reasonable in design, keeps apart unnecessary lubricant oil and axis hole, can effectively prevent lubricant oil from entering in power and water machine, effectively improves the working life of water pump; When needs profit change oil lubricate time, only need shirtsleeve operation can by oil filling in axis hole, effectively ensure lubrication indispensable in axis hole.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of preferred embodiment that the utility model provides.
In figure, 1, body; 11, axis hole; 12, shoe cream room; 13, oil-through hole; 14, articulated section; 2, plug; 31, guide holder; 32, guide rod; 33, spring; 34, groove; 4, driveshaft.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Pump cover as shown in Figure 1, comprises body 1, and body 1 is provided with the axis hole 11 passed for rotating shaft and the shoe cream room 12 being located at axis hole 11 periphery, and shoe cream room 12 is communicated with axis hole 11 by oil-through hole 13.As shown in Figure 1, one end place being positioned at shoe cream room 12 at oil-through hole 13 is provided with rubber plug 2, being provided with in shoe cream room 12 for guiding plug 2 along the guide structure of the axial motion of oil-through hole 13, in shoe cream room 12, being also provided with the driving structure for driving plug 2 to move along guide structure.
Concrete, as shown in Figure 1, guide structure comprises the coaxial guide holder 31 arranged and the guide rod 32 be arranged in guide holder 31 with oil-through hole 13, plug 2 is located at the outer end of this guide rod 32, also be provided with the spring 33 that its one end acts on guide rod 32 the inner in guide holder 31, the other end of spring 33 acts on guide holder 31.
As shown in Figure 1, driving structure comprises the driveshaft 4 being articulated with shoe cream room 12 sidewall, one end of this driveshaft 4 acts on guide rod 32, and the outer end of this driveshaft 4 extend out to the outside of described shoe cream room 12, and the sidewall of shoe cream room 12 has the articulated section 14 for support drive bar 4.
