Abstract
The utility model discloses a kind of oil well pump, comprises the pump housing, and the upper end of the described pump housing is plunger, and pump housing center arranges center-pole, and described center-pole is moved up and down by the motivational drive on ground; Described center-pole is hollow shaft structure, arranges cable in the hollow shaft of described center-pole, and the below of described hollow shaft arranges heating head, and described cable is electrically connected with the heater in heating head.The utility model has the advantages that: owing to being provided with cable passage in center-pole, therefore, add heating equipment, like this, crude oil is thinning after heating, can meet the requirement of winter construction.
Description
Technical field
The utility model relates to oil equipment field, is a kind of oil pump specifically.
Background technique
Panjin oil field is positioned at the northeast of China, and when weather conditions determine winter construction, temperature is lower, and in addition, the crude oil in Panjin oil field is viscous crude, is very easy to solidify.Existing oil well pump comprises the pump housing, center-pole; The top of described center-pole arranges moving valve, and the below of described center-pole arranges standing valve; When center-pole is up, moving valve is closed, and standing valve is opened, and when center-pole is descending, standing valve cuts out, and moving valve is opened and pumped in ground storage device by crude oil.Because Panjin oil field is when petroleum production, viscosity of crude is comparatively large, and especially during winter job, common oil well pump can not use, in the urgent need to a kind of oil well pump used for Liaohe Oil Field.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide the oil well pump that a kind of applicable Panjin oil field uses, and concrete technological scheme is as follows:
A kind of oil well pump, comprise the pump housing, the upper end of the described pump housing is plunger, and pump housing center arranges center-pole, and described center-pole is moved up and down by the motivational drive on ground; It is characterized in that: described center-pole is hollow shaft structure, arranges cable in the hollow shaft of described center-pole, and the below of described hollow shaft arranges heating head, and described cable is electrically connected with the heater in heating head.
The utility model has the advantages that: owing to being provided with cable passage in center-pole, therefore, add heating equipment, like this, crude oil is thinning after heating, can meet the requirement of winter construction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Illustrate the utility model below in conjunction with accompanying drawing, as shown in Figure 1, the utility model comprises the pump housing 1, and the upper end of the described pump housing 1 is plunger 2, and pump housing center arranges center-pole 4, and described center-pole is moved up and down by the motivational drive on ground; Described center-pole 4 is hollow shaft structure, arranges cable in the hollow shaft of described center-pole 4, and the below of described hollow shaft 4 arranges heating head 7, and described cable is electrically connected with the heater in heating head 7.The top of described center-pole 4 arranges moving valve 3, and the below of described center-pole 4 arranges standing valve 5; When center-pole 4 is up, moving valve 3 is closed, and standing valve 5 is opened, and when center-pole 4 is descending, standing valve 5 cuts out, and moving valve 3 is opened and pumped in ground storage device by crude oil.
