Pulse pump of fuel heater

Abstract

The invention relates to a pulse pump of a fuel heater. The pulse pump comprises a shell, one end of the shell is provided with an oil inlet connecting sleeve, and the other end of the shell is provided with an oil outlet connecting sleeve; and the pulse pump is characterized in that the end, provided with the oil outlet connecting sleeve, of the shell is provided with a plug assembly parallel tothe oil outlet connecting sleeve, an oil pumping assembly is arranged in the shell, a concentrically-arranged coil support assembly is arranged on the outer side of the oil pumping assembly and is connected with the plug assembly through an insertion sheet, the plug assembly is electrically connected with the external fuel heater, the oil pumping assembly comprises a plunger and a plunger sleeve arranged outside the plunger in a sleeving manner, one end of the oil inlet connecting sleeve is provided with a first cavity, one end of the oil outlet connecting sleeve is provided with a second cavity, a first limiting device is arranged at the end, close to the first cavity, of the plunger, and a second limiting device is arranged at the end, close to the second cavity, of the plunger. The pulse pump has the beneficial effects of being stable in work, compact in structure and small in noise during work.

Description

technical field [0001] The invention relates to the field of oil pumping devices for fuel heaters, in particular to a pulse pump for fuel heaters. Background technique [0002] At present, the existing fuel heaters generally do not have their own fuel tanks, and need to take oil from the fuel tanks of large machinery or vehicles to be heated. Due to the uncertainty of the installation position of the fuel heater, sometimes the oil supply system required by large-scale mechanical equipment and vehicles needs to be installed with a long oil pipeline due to the long installation distance. The heating unit locks up. [0003] And the oil pumping device of existing fuel oil heater works unstable, and the fuel oil heater often cannot start in time because the fuel oil supply is not in place after initial installation. Contents of the invention [0004] The technical problem to be solved by the present invention is to address the above-mentioned deficiencies in the prior art, ...
