The pump is characterized in that both ends of the rotor is fixed with a seal sleeve via pins, the seal sleeve are provided with a seal body, the seal body is provided with the vice impeller of power seal and the mechanical seal of static seal successively, the upper part of the seal body cooperates with a pump casing and the bearing body in order, the seal bearing and the seal bearing body are arranged in the chamber of the seal body; The pump is special in structure, can reduce the wearing of the mechanical seal and the leakage rate of the pump and prolong the service lifetime.
Description
Technical field
The utility model relates to a kind of double-screw oil-gas mixed defeated pump, especially relates to the novel double-screw oil-gas mixed defeated pump of a kind of energy aneroid idle running.
Background technique
At present, known double-screw oil-gas mixed defeated pump mostly is single mechanical end face seal or packing seal.This seal arrangement can be in hydrocarbon content the gas ratio low be that sealing effect is good, but the gassiness ratio increases, or gas content is 96% o'clock, machine envelope rotating ring and the dry grinding of stationary ring surface of contact and leak serious, sanitary condition difference and inflammable being prone to accidents behind the oil and gas leakage.Machine envelope damage back is changed inconvenient, increases labor intensity.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of structure uniqueness is provided, can seals the leakage rate of wearing and tearing, can reduce pump, the novel double-screw oil-gas mixed defeated pump that improves the working life of oil-gas mixed delivery pump by the minimizing machine.
The utility model is realized in the following way:
A kind of novel double-screw oil-gas mixed defeated pump, it comprises rotor, rotor is combined with bearing support on the middle part, the outside framework oil seal and the bearing that cooperate successively between bearing support and the rotor, be combined with bearing gland on the bearing, it is characterized in that: there is a stuffing box gland at the two ends at described rotor by dowel fixes, sealing puts seal is housed, in seal, adorn the machine envelope of the sub-propeller and the static seal of dynamic seal successively, be combined with pump case and described bearing support successively on the top of seal, in the seal cavity, be combined with stuffing box bearing and stuffing box bearing body;
On described bearing support, be provided with shoe cream room, between shoe cream room and described stuffing box bearing body, be provided with oil filling pipe.
The utility model has following effect:
1) structure uniqueness: it comprises rotor the device that the utility model provides, rotor is combined with bearing support on the middle part, the outside framework oil seal and the bearing that cooperate successively between bearing support and the rotor, be combined with bearing gland on the bearing, it is characterized in that: there is a stuffing box gland at the two ends at described rotor by dowel fixes, sealing puts seal is housed, in seal, adorn the machine envelope of the sub-propeller and the static seal of dynamic seal successively, be combined with pump case and described bearing support successively on the top of seal, in the seal cavity, be combined with stuffing box bearing and stuffing box bearing body.
2) pump does not corrode pump shaft, impurity in the running and can not cause damage, increase the service life sealing: the device that the utility model provides has added stuffing box gland to double-screw oil-gas mixed defeated pump seal place, front end band sub-propeller at stuffing box gland, the centrifugal force that sub-propeller produces withstands the liquid that flows to mechanical seal place, reduced the pressure of mechanical seal place, pump oil gas medium does not in the running corrode pump shaft, and the impurity in the oil gas can not cause damage to sealing.The chamber that lubricating oil filling is arranged in the sub-propeller back, to the envelope of the machine in the chamber, bearing, the working life of the lubricated raising of Sealings such as oil sealing part.And it is convenient that all parts are assembled into integral installation.
3) all parts are assembled into integral installation conveniently: the two ends of rotor dress stuffing box gland of two screw pump oil-gas mixed delivery pump uses dowel fixes on rotor, in stuffing box gland, adorn the same rotor seal of 0 type circle, seal is housed on the stuffing box gland, the machine envelope of the sub-propeller of dress dynamic seal and static seal in seal, be contained in the stuffing box bearing of sealing body cavity, and the part in the logical shoe cream room lubrication and seal body of oil filling pipe is arranged on the seal.The stuffing box bearing gland is contained on the seal, the lubricant oil on the bearing gland in the dress skeleton oil seal seal.Adorn seal in the bearing support, outside framework oil seal, bearing, bearing gland, bearing support is installed on the pump case, and all parts are assembled into integral installation conveniently.
