Abstract
An oil-submerged pump capable of transmitting oil products in mass flow is characterized by comprising a pump body, an explosion-proof electric machine, a centrifugal pump, an oil product main flow passage and an inner cooling channel, wherein the explosion-proof electric machine and the centrifugal pump are fixedly installed in the pump body, a stator and a rotor are arranged in the explosion-proof electric machine, the inner cooling channel is arranged in a gap between the stator and the rotor, and the oil product main flow passage penetrates through the pump body. A working procedure of the oil-submerged pump capable of transmitting the oil products in mass flow includes the steps that the explosion-proof electric machine drives the centrifugal pump to work, the centrifugal pump inhales the oil products into the pump body, liquid oil products enter the oil product main flow passage, a part of the liquid oil products are flowed out of the pump body through the oil product main flow passage, and a part of the liquid oil products enter the inner cooling channel. Due to the fact that the inner cooling channel is added, the oil-submerged pump capable of transmitting oil products in mass flow and the working procedure of the oil-submerged pump capable of transmitting oil products in mass flow has the advantages of reducing temperature of the high-power explosion-proof electric machine in work and controlling temperature within a temperature range allowed by standards and specifications.
Description
(1) technical field:
The present invention relates to a kind of oil-immersed pump of transporting oil, particularly be a kind of oil-immersed pump and method of work thereof of large flow transporting oil.
(2) background technique:
At present, the oil product of generally selling and using on market, be generally at vehicle-mounted oil tank (or claiming mobile oil storage tank) and fixedly be provided with the system of mutual transporting oil between oil storage tank (or claim fixedly oil storage tank), this system adopts the negative pressure self-suction fuel feeding, namely by pipeline mounted pump, oil product is sucked in oil pump, in oil pump after supercharging, discharge by deaerator the gas that is mixed in oil product and be transported to again fixedly in oil tank.The major defect of pipeline mounted pump is easily to produce vapour lock under high temperature and high height above sea level condition, causes oil pump capacity to descend, and is even not fuel-displaced.Cause the waste of working efficiency decline and resource, also have simultaneously potential safety hazard.
Gradually adopt now oil-immersed pump to solve the problems referred to above, but the oil-immersed pump of large flow or blank is mainly because want large flow transporting oil, must adopt powerful anti-explosion motor, the heating of himself has exceeded the scope that regulation allows.
(3) summary of the invention:
The object of the present invention is to provide a kind of oil-immersed pump and method of work thereof of utilizing the large flow transporting oil of positive pressure propelling movement type fuel feeding, it can overcome the deficiencies in the prior art, and employing increases the method for internal cooling channel, reduced the temperature of high-power explosion-proof motor, temperature when making its work is within being controlled at the temperature range of standard code permission.
Technological scheme of the present invention is: a kind of oil-immersed pump of large flow transporting oil is characterized in that it comprises the pump housing, anti-explosion motor, centrifugal pump, oil product sprue and internal cooling channel; Described anti-explosion motor and centrifugal pump are fixedly mounted in the pump housing; Stator and rotor are arranged in described anti-explosion motor; Described internal cooling channel is placed in the gap between stator and rotor; Described oil product sprue runs through in the pump housing.
