Abstract
The utility model discloses a grease pump. The pump comprises a grease cylinder and a piston, wherein the bottom of the grease cylinder is connected with a grease inlet and a grease outlet; the top of the piston is connected with a pressure lever; and the pressure lever extends out of a grease cylinder cover through a hole in the grease cylinder cover and moves up and down along with the piston. According to the grease pump, a manner of conveying grease by spring pressure in a vacuum environment is eliminated while a manner of conveying the grease by the gravities of the piston and the pressure lever under a standard atmospheric pressure is adopted, so that air mixed during grease filling is exhausted automatically without vacuumizing again, and the grease pump can work normally and directly under the standard atmospheric pressure.
Description
Technical field
The oil pump of using when the utility model relates to a kind of production and processing.
Background technique
Existing grease pump is to carry out fuel feeding under vacuum state; oil cylinder is hermetic; piston head is connected with oil cylinder cover by a spring; keep vacuum state; because piston can't avoid entering air in the process of motion repeating to refuel; cause the fuel feeding fault often to shut down, and press easily quick-fried causing long downtimes during oil starvation.
The model utility content
The utility model provides a kind of grease pump, the cancellation butter utilizes spring pressure to send oily mode in vacuum environment, adopt standard atmosphere to depress by piston and depression bar self gravitation and send oily mode, automatically discharge the air of bringing into when refueling, need not to vacuumize, grease pump is directly depressed and can be worked at standard atmosphere again.
A kind of grease pump that the utility model provides, comprise oil cylinder and piston, described oil cylinder bottom is connected with filler opening and oil outlet, and described piston head connects a depression bar, described depression bar stretches out outside the oil cylinder cover by the hole on the oil cylinder cover, and described depression bar is with piston oscilaltion campaign.
The oil cylinder cavity that is positioned at described piston head communicates with external environment condition by the hole on the described oil cylinder cover.
The advantage that the utlity model has is as follows:
1) easy to operate, need not to vacuumize;
2) Environmental Conditions can be depressed normal operation at normal atmosphere;
3) simple in structure, cost is low, avoids the oil starvation Decrepitation Phenomena fully;
4) automatic vent need not independent exhaust.
Description of drawings
Fig. 1 is the grease pump structural representation that the utility model provides.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, a kind of grease pump that the utility model embodiment provides, comprise oil cylinder 1 and piston 2, described oil cylinder bottom is connected with filler opening 3 and oil outlet 4, described piston head connects a depression bar 5, described depression bar stretches out outside the oil cylinder cover 6 by the hole on the oil cylinder cover, and described depression bar is with piston oscilaltion campaign.The oil cylinder cavity that is positioned at described piston head communicates with external environment condition by the hole on the described oil cylinder cover, the cancellation butter utilizes spring pressure to send oily mode in vacuum environment, adopt standard atmosphere to depress by piston and depression bar self gravitation and send oily mode, automatically discharge the air of bringing into when refueling, need not to vacuumize, grease pump is directly depressed and can be worked at standard atmosphere again.It is simple in structure, and cost is low, avoids the oil starvation Decrepitation Phenomena fully.
