Problems solved by technology
[0005] Therefore, the lubrication method of the front guide sleeve of the centrifugal acid drive machine cannot completely solve the problem of combined seal corrosion and wear, and the forced lubrication method cannot be used to solve the lubrication problem of the front guide sleeve.
However, if the non-forced lubrication method is used, there may be problems such as poor lubrication of the front guide sleeve, locking of the pushing shaft or accelerated wear.
Therefore, in the prior art, there is no lubricating system for the front guide sleeve of the piston pusher centrifugal acid drive machine that can prevent the production of acid oil and effectively ensure that the front guide sleeve is well lubricated.

The invention discloses a front guide sleeve lubricating system of a piston pushing centrifugal acid drive machine. The front guide sleeve lubricating system of the piston pushing centrifugal acid drive machine is applied in the field of chemical cellulose production. The front guide sleeve lubricating system of the piston pushing centrifugal acid drive machine can prevent acid-soluble oil from corroding and damaging a hydraulic system and a lubricating system of the acid drive machine, and can also effectively ensure good lubrication of a front guide sleeve. The front guide sleeve lubricating system of the piston pushing centrifugal acid drive machine comprises an oil cylinder, a hollow spindle, a pushing shaft, a rear guide sleeve and the front guide sleeve. The pushing shaft is located in a cavity of the hollow spindle, the pushing shaft is of a hollow structure which enables the front end and the rear end of the pushing shaft to be communicated, the front end of the pushing shaft is provided with an lubricating oil hole, and the hollow structure of the pushing shaft and the outer wall of the pushing shaft are communicated through the lubricating oil hole. By the adoption of unforced lubrication, acid oil can be effectively prevented from being driven to enter the hydraulic system and the lubricating system of the acid drive machine by an oil pump.
Description
technical field [0001] The invention relates to a lubricating system for a front guide sleeve of a piston pusher centrifugal acid drive machine, in particular to a front guide sleeve lubrication system for a piston pusher centrifugal acid drive machine applied in the field of chemical cellulose production. Background technique [0002] The lubrication method of the front guide sleeve of the piston pusher centrifugal acid drive machine in the prior art all adopts the hydraulic system to supply oil, and the lubricating oil implements forced lubrication to the front guide sleeve under the action of pressure. This lubricating method is characterized by fast circulation of lubricating oil for the front guide sleeve, good cooling and lubricating effects, low wear and long life, and is the preferred lubricating method for large and medium-sized centrifuges. [0003] However, as far as the piston pusher centrifugal acid drive machine for nitrocellulose production is concerned, the c...
