Abstract
Disclosed is a steam-operated consistent fat pump used for transmitting consistent fat under heavy pressure. The pump is characterized in that a reversing arrangement comprises a pilot valve, a pilot change-over valve and an air storage chamber. The pilot change-over valve and the pilot valve are arranged coaxially in the pump body, the air storage chamber is formed by the cavity between the pilot change-over valve and the pilot valve. The air storage chamber arranged with an air inlet and an air outlet is connected with the upper and the lower cavities of a cylinder via upper and lower discharge pipes. An air plunger is in linkage with an oil plunger via a one-way valve which is arranged in front of the oil plunger, the cylinder is arranged on the side surface of the oil plunger, and a consistent fat inlet and a consistent fat outlet are arranged on the cylinder. The utility model has the advantages of large water discharge and high pressure of oil-discharge. The consistent fat pump can be adjusted according to the conduit line and the working requirement within the maximum pressure range. The oil pump stops working when the discharging pressure reaches to a certain value, and the oil pump is to recover work automatically.
Description
The utility model relates to high pressure grease lubricating system technical field, and is particularly a kind of in grease centralized lubrication equipment, the pneumatic high-voltage dry oil pump that the high-pressure delivery drier oil is used.
The pneumatic dry oil pump of present domestic manufacturing and use mainly exists two big shortcomings, and the one, the selector valve complex structure, it is unreliable to work, and the rate of fault height often takes place " stuck phenomenon ", next is that the drier oil piston " grinds dead ", and cylinder body and oily piston are damaged, and causes complete machine to be scrapped.
It is good that the purpose of this utility model provides a kind of safe and reliable property, the pneumatic dry oil pump that the oil transportation service radius is big.
The utility model is to realize like this, it comprises the gas piston, the oil piston, one-way valve, selector valve, pilot reversing valve, cylinder, oil cylinder and reversing arrangement, it is characterized in that reversing arrangement comprises pilot valve, pilot reversing valve and gas storage chamber, pilot reversing valve is installed in the pump housing with pilot valve is coaxial, cavity between pilot reversing valve and the pilot valve constitutes gas storage chamber, the gas storage chamber that has suction port and relief opening is by last, on following outlet pipe and the cylinder, cavity of resorption is connected, be connected by one-way valve between gas piston and the oily piston, front end at oily piston is provided with one-way valve, be provided with oil cylinder in its side, oil cylinder is provided with drier oil import and drier oil outlet.
It is big to the utlity model has oil drain quantity, and the advantage that oil extraction pressure is high, but length, the need of work of root a tree name pipeline are regulated arbitrarily in the maximum pressure scope, and after the pressure of discharging reached predetermined pressure, oil pump quit work; Oil pump can be resumed work automatically when the pressure in the pipeline reduces, and its important technological parameters is as follows:
Model suction pressure drier oil outlet pressure oil supply piezometric force rate
MPa MPa liter/minute
BY-MZ 0.3-0.7 20-40 1-8 40-70∶1
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the structural representation of pneumatic dry oil pump,
