Filter screen of fuel oil pump

Abstract

The invention discloses a filter screen of a fuel oil pump. The filter screen comprises a connecting head, a screen cloth skeleton and screen cloth, and is characterized in that an oil inlet is arranged in one end part of the lower end of the connecting head; longitudinal blocking pieces are respectively arranged on the lower end surfaces of the two end edges of the oil inlet in a downwards extending manner; an oil outlet with an oil inlet joint is arranged in the left end part on the lower end surface of one end part of the upper end of the connecting head, and a locking ring seat with a center hole on the bottom surface is arranged at the right end part of one end part of the upper end of the connecting head in an upwards extending manner; clamping buckles are evenly distributed at the upper end part of the inner wall of the locking ring seat; an arc-shaped locking ring window is arranged in the right side wall of the locking ring seat; a locking ring formed by a ring-shaped body and upwards-extending arc-shaped blades evenly distributed on the upper end surface of the ring-shaped body is arranged in the locking ring seat; the screen cloth skeleton consists of a framework and fillets distributed in the framework; and raised longitudinal support plates are distributed on the upper end surfaces of the longitudinal fillets; the two ends of one end part of the upper end of the framework are respectively connected with the two ends of the lower end edge of the oil inlet to form a whole body; and the screen cloth is wrapped outside the L-shaped screen cloth skeleton after being folded and is sealed in a welded manner. The filter screen is suitable for being used by the fuel oil pump.

Description

technical field [0001] The invention relates to a filter screen, in particular to a fuel pump filter screen. Background technique [0002] Usually, the mesh frame and connectors of the fuel pump filter screen used in fuel pumps are made separately, and then the mesh frame and connectors are assembled into one, which makes the product structure complex, not only increases the number of molds and fixtures, Moreover, it is necessary to use many different processing equipments, which also increases the processing and assembly steps and is cumbersome, thus not only prolonging the processing and manufacturing process, reducing production efficiency, but also increasing manufacturing costs. In addition, the fuel pump filter screen is The installation and fixing reliability in the narrow space in the oil storage tank is poor. In short, it is not conducive to products entering the highly competitive market. Contents of the invention [0003] The purpose of the present invention i...
