Description

Air-cooled gasoline cleaner

Technical field

The utility model relates to cleaning machine, particularly relates to air-cooled gasoline cleaner, is mainly used in to clean automobile, glass door and window, garden road, animal farm place etc.

Background technology

Cleaning machine mainly is made of water pump, power-equipment and hydraulic giant, and the output shaft of power-equipment drives the power shaft of water pump, ejects from hydraulic giant after changing the low-pressure water circulation into High-Pressure Water by water pump.Power-equipment adopts gasoline engine or diesel engine or motor usually.There is following defective in existing gasoline engine cleaning machine: water pump does not have cooling device, cleaning machine can generate heat when long-time the use, if can not get timely heat radiation, the operating efficiency that can influence cleaning machine reaches stable, service life is short, and existing gasoline engine drives water pump by transmission mechanism, so it is big to form whole cleaning machine volume, and complex structure.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming that prior art exists, to provide a kind of water pump directly to be driven by power, compact conformation, and volume is little, and is in light weight, air cooling equipment is installed, good heat dissipation effect, the air-cooled gasoline cleaner of long service life simultaneously in transmission.

The technical scheme of the air-cooled gasoline cleaner of the utility model is: comprise gasoline engine and water pump, gasoline engine output mounting flange and output shaft, described water pump comprises pump seat, be equipped with power shaft in the pump seat, between power shaft outer ring and the pump seat deep groove ball bearing is installed, one end of power shaft has the inclined-plane, thrust ball bearing is housed on the inclined-plane, thrust ball bearing contacts with plunger, on pump seat, pacify the pump housing, plunger is installed on the pump housing through plunger spring, the pump housing one end is connected with screw with pump seat, and the other end of the pump housing is installed pump head, the water check valve is housed in the pump head into and goes out water one-way valve, pump head is shaped on water inlet and delivery port, delivery port connects spray gun through outlet pipe, it is characterized in that an end of described output shaft of gasoline engine is shaped on keyway, is equipped with key in the water pump power shaft, the water pump power shaft directly connects with output shaft of gasoline engine by key, outside power shaft or output shaft fan blade is installed.

Of the present utility model a kind of air-cooled gasoline cleaner disclosed, water pump is directly installed on the gasoline engine, gasoline engine and water pump closely connect into an integral body, by fitting key in the axis hole of water pump power shaft, power shaft is directly connected with output shaft, pump is coaxial, both can guarantee the reliability that connects, also make compact conformation, complete machine is light and handy, conveniently moving.Outside power shaft or output shaft, fan blade is installed, not only cooling water pump but also for gasoline engine provides good radiating condition, protection water pump and complete machine can be worked steadily in the long term.

Description of drawings

Fig. 1 is that the fan blade of air-cooled gasoline cleaner is installed in structural representation on the power shaft;

Fig. 2 is that the fan blade of air-cooled gasoline cleaner is installed in structural representation on the output shaft.

The specific embodiment

The utility model relates to a kind of air-cooled gasoline cleaner, shown in Fig. 1-2, comprise gasoline engine and water pump, gasoline engine 1 output mounting flange 19 and output shaft 2, described water pump comprises pump seat 6, be equipped with power shaft 5 in the pump seat, deep groove ball bearing 17 is installed between power shaft outer ring and the pump seat, one end of power shaft 5 has the inclined-plane, thrust ball bearing 7 is housed on the inclined-plane, and thrust ball bearing contacts with plunger 10, the peace pump housing 16 on pump seat, plunger 10 is installed on the pump housing 16 through plunger spring 9, the pump housing one end is connected with screw 18 with pump seat, and the other end of the pump housing is installed pump head 12, water check valve 14 is housed in the pump head into and goes out water one-way valve 13, pump head is shaped on water inlet 15 and delivery port 11, delivery port connects spray gun through outlet pipe, it is characterized in that an end of described output shaft of gasoline engine 2 is shaped on keyway, is equipped with key 4 in water pump power shaft 5, the water pump power shaft directly connects with output shaft of gasoline engine by key, and fan blade 3 is installed outside power shaft 5 or output shaft 2.Water pump is directly installed on the gasoline engine 1, gasoline engine 1 closely connects into an integral body with water pump, by fitting key 4 in the axis hole of water pump power shaft 5, power shaft 5 is directly connected with output shaft 2, pump is coaxial, both can guarantee the reliability that connects, also makes compact conformation, complete machine is light and handy, conveniently moving.Fan blade 3 is installed, not only cooling water pump but also for gasoline engine provides good radiating condition, protection water pump and complete machine can be worked steadily in the long term outside power shaft 5 or output shaft 2.Gasoline engine 1 drives power shaft 5 and fan blade 3 rotations during work, because the end face of power shaft 5 installed thrust ball bearings 7 is inclined-planes, the distance of each point is inequality on thrust ball bearing 7 and the circumference that plunger 10 contacts, and plunger 10 is under the effect of plunger spring 9, an end of plunger all the time with thrust ball bearing 7 one end in contact.Therefore, the rotation of bearing block, it is reciprocating to drive plunger 10, when plunger during to left movement, pump head 12 cavity volume of plunger right-hand member increase, and form vacuum, water enters pump head 12 inner chambers by water inlet 15, water inlet check valve 14 under the effect of tap water pressure (or atmospheric pressure).When plunger moved right, pump head 12 cavity volume reduced, and the hydraulic pressure in the pump head improves, and water inlet check valve 14 is closed under the effect of spring, and the water in the pump head overcomes the pressure that water one-way valve 13 springs, opens out water one-way valve, discharges from go out water one-way valve.
