Quiet+ F
Close(2)
F
Floating: the Liquid level compensator floating block is to buoyancy;
G
Heavy: the weight of Liquid level compensator floating block;
F
Close: the Liquid level compensator floating block is faced the downward power of Liquid level compensator floating block with the contact seal of compensation lubricating cup falling tube;
F
Quiet: lubricant oil is to the pressure of Liquid level compensator floating block in the compensation lubricating cup.
Like this, pump of the present utility model compensation lubricating cup can be achieved as follows requirement:
1. the pump fuel tank is when normal oil level, and promptly riser 10 end openings and falling tube 4 end openings immerse under the pump oil level, adds 1 sealing of repairing mouth, and formula (1) condition satisfies, and pump fuel level in tank and compensation lubricating cup oil level remain unchanged.
2. when the pump fuel level in tank descended, promptly riser 10 end openings and falling tube 4 end openings exposed the pump oil level, and air enters compensation lubricating cup body 2 epicoeles by riser 10, and Liquid level compensator floating block 6 suffered buoyancy reduce F
Floating≤ G
Heavy+ F
Quiet, oil subsidy is gone into pump in the compensation lubricating cup, makes the pump oil level rise to normal oil level.
3. when the pump fuel tank refuels.When the pump fuel level in tank hanged down, Liquid level compensator floating block 6 separated with falling tube 4, and oil directly adds the pump fuel tank by compensation lubricating cup body 2 epicoeles, when the pump fuel level in tank rises to normal oil level, and F
Floating〉=G
Heavy+ F
Quiet, Liquid level compensator floating block 6 will compensate lubricating cup to be separated with the pump fuel tank, and oil can not add again, makes the pump fuel tank phenomenon can not occur adding.
4. when the compensation lubricating cup adds repairing, separated by Liquid level compensator floating block 6 with the pump fuel tank, can directly add benefit easily because the pump fuel tank, compensates lubricating cup at normal oil level.
5. multi-functional compensation lubricating cup is directly installed on the former pump oil level looking glass, and therefore compensating lubricating cup body 2 cavity of resorptions can be used as pump fuel level in tank monitor window, and is convenient directly perceived.
6 position-limiting actions of 7 pairs of Liquid level compensator floating blocks of wherein said limit body guarantee that Liquid level compensator floating block 6 can only be floating up and down in limit body 7, and can not be floated to other place, so need not do concrete requirement to its shape.
Wherein said Liquid level compensator floating block 6 can be spheroid, cylindrical body or cone, gets final product but must guarantee that it can float on the machine oil in lubricating cup body 2 cavity of resorptions.
