Abstract
The utility model discloses an impulse type oil pump, which comprises a pump body, pump body one end is equipped with the oil feed mouth, the oil feed mouth below is equipped with the oil feed mouth adapter sleeve in the pump body, its characterized in that: the oil inlet nozzle is detachably mounted on the pump body, and a filtering device is detachably mounted between the oil inlet nozzle and the oil inlet connecting sleeve. The utility model has the advantages that: the impurity in the oil is filtered, so that the purity of the oil entering the fuel oil heater from the pulse type oil pump is higher, the service efficiency of the oil is improved, and the performance of the fuel oil heater is better.
Description
The technical field is as follows.
The utility model relates to a fuel heater technical field especially involves an impulse type oil pump.
Background
Because the fuel oil heater is not provided with a fuel tank, the fuel oil heater needs to take fuel oil from the fuel tank of a large machine or a vehicle to be heated; due to the uncertainty of the installation position of the fuel heater, sometimes long oil pipelines need to be additionally installed in oil supply systems required by large-scale mechanical equipment and vehicles due to long installation distance, and fuel cut sometimes occurs when consumption is suddenly increased, so that the fuel heating equipment is locked. The oil pumping device of the conventional fuel oil heater is unstable in work, and the fuel oil heater cannot be started in time due to insufficient fuel oil supply after being installed for the first time; therefore, through continuous research and development, those skilled in the art have developed a pulse type oil pump for compensating for fuel supply when the fuel supply is insufficient.
In the working process of the pulse type oil pump, oil enters from an oil inlet, passes through the oil inlet control valve and the oil outlet control valve, and enters the fuel heater from an oil outlet, a traditional pulse type oil pump body is not provided with a filtering device, and the oil which enters the fuel heater is carried with impurities due to the fact that the oil contains the impurities, so that the performance of the fuel heater is influenced, the control valve is blocked due to excessive impurities, and the service life of the pulse type oil pump is influenced; and traditional pulsed oil pump oil inlet and pump body be integrated into one piece's unable dismantlement.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose: in order to overcome the defects existing in the prior art, the utility model provides an impulse type oil pump.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an impulse type oil pump, includes the pump body, pump body one end is equipped with the oil feed mouth, be equipped with the oil feed mouth adapter sleeve, its characterized in that in the pump body below the oil feed mouth: the oil inlet nozzle is detachably mounted on the pump body, and a filtering device is detachably mounted between the oil inlet nozzle and the oil inlet connecting sleeve.
Through taking above-mentioned technical scheme, filter equipment filters the impurity in with oil, dismantles the oil inlet nozzle, takes out filter equipment from the pump body, clears up the impurity among the filter equipment, prevents that impurity from piling up too much influence filtering quality in filter equipment.
The utility model discloses the further scheme does: the oil inlet nozzle is in threaded connection with the pump body, the filtering device is a filtering net, one end of the filtering net is closed, and the other end of the filtering net is provided with an open cavity; the scheme can also be as follows: the oil inlet nozzle is characterized in that the filtering device is a filtering net, one end of the filtering net is closed, one end of the filtering net is provided with a cavity, one end of the filtering net provided with the cavity is sleeved with a protective sleeve, threads are arranged on the protective sleeve, an integrally formed connecting part matched with the protective sleeve is arranged at the upper bottom of the oil inlet nozzle, internal threads are arranged on the connecting part, and the oil inlet nozzle is in threaded connection with the filtering net.
By adopting the technical scheme, the oil inlet nozzle is in threaded connection with the pump body, the oil inlet nozzle is convenient to disassemble and install, simple in structure and easy to realize, and the filter screen can be replaced and cleaned by abutting and fixing the protective sleeve and the oil inlet connecting sleeve; the protective sleeve is connected with the oil inlet nozzle in a threaded manner, so that the dismounting is convenient and the structure is simple.
The utility model discloses the further scheme does: and a sealing element is arranged between the oil inlet nozzle and the pump body.
Through adopting above-mentioned technical scheme, prevent that oil from leaking from oil inlet nozzle and pump body junction, play sealed effect.
The utility model discloses the further scheme does: the sealing element is an O-shaped sealing ring.
By adopting the technical scheme, the O-shaped sealing ring has good sealing effect and low price.
The utility model discloses the further scheme does: the oil inlet nozzle is a hexagon nut.
By adopting the technical scheme, the oil inlet nozzle is in the shape of the hexagon nut, so that the whole appearance is more attractive.
