Explosion proof vacuum pump

Piston oil-free vacuum pumpAlso known as reciprocating vacuum pump, it is divided into single cylinder and multi cylinder structures, characterized by a high head. Suitable for transporting oil emulsions without solid particles at room temperature. Used for water injection, oil injection, and oil recovery in oil fields and coal seams; The power pump of the chamber press and hydraulic press, hydraulic sand cleaning, and ammonia liquid transportation in fertilizer plants. If the overcurrent component is made of stainless steel, corrosive liquids can be transported. In addition, depending on the different structural materials, it can also transport high-temperature tar, mineral mud, high concentration mortar, high viscosity liquids, etc. Oil free piston vacuum pump is suitable for high-pressure and low flow applications, especially when the flow rate is less than 100 m3/hour and the discharge pressure is greater than 9.8 megapascals, it shows its high efficiency and good operating performance.

Characteristics and working principle: It is achieved by a fixed seal and a piston moving forward and backward. A piston vacuum pump relies on the reciprocating motion of the piston to periodically change the working volume of the pump chamber, achieving the suction and discharge of liquids. The seal of the plunger pump is installed on the plunger through a smooth cylinder wall. It mainly uses the reciprocating motion of the plunger in the pump cylinder to create a volume change between the plunger and the pump wall, repeatedly sucking and discharging liquid and increasing its pressure.
