Description
Technical Field
The utility model belongs to the technical field of fuel heater, concretely relates to adjustable heater oil pump.
Background
The fuel oil heater is mainly used in large-scale mechanical equipment and vehicles, and has the working principle that when a plug is connected with a power supply, a coil is powered on and powered off at a constant frequency, so that electromagnetic attraction with a constant frequency is generated, when the fuel oil heater is powered on, an armature moves towards the direction of an oil outlet connecting sleeve along a plunger under the action of the electromagnetic attraction, fuel oil enters the oil inlet connecting sleeve due to the leftward movement of the armature, enters the plunger through an oil inlet hole of the plunger, at the moment, because the inside of the fuel oil heater is in a vacuum state, a steel ball is pressed downwards under the action of negative pressure to open an oil outlet hole, the fuel oil enters an oil outlet control valve of the oil outlet connecting sleeve through the oil outlet hole, the electromagnetic attraction disappears when the power is off, the steel ball resets under the action of a return spring, the armature resets under the action of the return spring of the armature, and the.
The working flow of the oil pump of the existing fuel heater is not adjustable, and when the working flow of the oil pump of the existing fuel heater needs to be a little larger or smaller, the oil pump of the existing fuel heater cannot be realized, so that the operation is very inconvenient; and the abrasion of a steel ball in the oil inlet control valve of the existing oil pump of the oil burner is fast, and the oil is easy to leak.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to solve the above-mentioned deficiencies of the prior art,
an adjustable heater oil pump is provided.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an adjustable heater oil pump, includes the shell, the shell both ends are equipped with oil inlet, oil-out one end is connected with oil outlet control valve one end, the oil outlet control valve other end is connected with the control valve that admits oil, oil outlet control valve top is equipped with the plunger, is equipped with the oil pocket between plunger and the oil outlet control valve, the plunger passes through armature fixed mounting in the shell, be equipped with sealed return subassembly in the oil outlet control valve, sealed return subassembly includes return spring, steel ball, the steel ball is located return spring, and the steel ball forms sealedly with oil outlet control valve inner wall butt, its characterized in that: 12 edges are arranged on the steel ball, edges are formed between two adjacent edges, two symmetrical edges on the steel ball are abutted against the inner wall of the oil outlet control valve to form sealing, the oil outlet control valve is in threaded connection with the shell, and the joint of the oil outlet control valve and the shell thread is coated with thread glue after being adjusted.
Adopt above-mentioned technical scheme, go out through threaded connection between oil control valve and the shell, when going out oil control valve outward toward when revolving, oil pocket inner volume grow, the working distance of plunger also becomes long, the oil pocket inner space is big more, and flow is just big more, the utility model discloses under the condition of inhaling journey 2m, poplar journey 3m, pulse width 48ms, frequency 8Hz, the plunger operation 1000 times's working flow can be realized adjusting between 16-36ml, scribbling the thread glue and make it can not become flexible in the department of going out oil control valve and shell threaded connection after adjusting, the fastening is reliable, utilizes the edges and corners to seal on the steel ball and can reduce wear, long service life, and the leakproofness is better.
An adjustable heater oil pump as described above may further be arranged to: the front end of the oil outlet control valve is provided with a buffer cushion, and the buffer cushion is a polyurethane buffer cushion.
By adopting the technical scheme, the polyurethane buffer cushion is arranged at the front end of the oil outlet control valve, so that the impact of the plunger on the oil outlet control valve in the operation process is reduced, and a shock absorption effect is also realized; and the polyurethane has the characteristics of oil resistance, wear resistance, elasticity, high hardness and the like, so the selected polyurethane cushion has better effect.
An adjustable heater oil pump as described above may further be arranged to: and a sealing ring is arranged between the oil outlet control valve and the oil inlet control valve.
By adopting the technical scheme, the sealing ring is arranged between the oil outlet control valve and the oil inlet control valve, so that oil leakage between the oil outlet control valve and the oil inlet control valve can be prevented.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
