The compressor of all the above-mentioned types and the problem existing for pump, or fretting wear is serious, energy loss large, leak large, inefficiency, or processing technology is complicated, precision is high, or reciprocal inertia force is difficult to balance, vibration is large, the easily damaged parts life-span is short and poor reliability.
Summary of the invention
The purpose of this utility model is to provide that a kind of output power is high, the abreast-type synchronous revolving mixing pump of good stability.
The technological scheme that the utility model is taked is: a kind of abreast-type synchronous revolving mixing pump, comprise housing, two main shafts, two cylinders and two rotors are set up in parallel in described housing, two described main shafts are connected by driving gear, and described cylinder and spindle eccentricity install and the center of cylinder is 180 degree relative to the phase difference of main shaft; Described rotor be arranged on drive its synchronous axial system main shaft on and rotor contact with cylinder retention wire, rotor is provided with slide plate, crescent shape cavity between cylinder and rotor is divided into oil suction chamber and oil-discharging cavity by described slide plate, the cylinder relative with oil suction chamber is provided with filler opening, the rotor corresponding with oil-discharging cavity is provided with oil drain out.
Described cylinder is fixed by cylinder upper cover and lower cover of air cylinder, and cylinder upper cover and lower cover of air cylinder are respectively by rack bearing and body bearings, and rack bearing is arranged on eccentric mounting, and one end of eccentric mounting and body is fixedly linked.
Two described main shafts, wherein a main shaft is connected with motor as transmission main shaft, and the two ends of another root main shaft are all positioned at body and its one end is connected by driving gear with described transmission main shaft, drive it to rotate by transmission main shaft.
Skateboards slot established by described rotor, and one end of slide plate is arranged in skateboards slot, and the other end and the cylinder of slide plate are hinged and connected.
Further, described cylinder is provided with circular arc skateboards slot, and the arc end of described slide plate is inserted in described circular arc skateboards slot and realizes being hinged and connected.
The inlet and outlet pressure of two described cylinders is identical or one high, one low.
Described rotor is provided with suction valve.
The beneficial effects of the utility model are improved the qualitative difference of traditional mixing pump stability, the problem that delivery efficiency is low; By the output power arranging two cylinders in body, two rotors strengthen mixing pump, Simultaneous Stabilization, working efficiency and reliability have also been obtained raising, and for ease of maintenaince, during a cylinder generation problem, another cylinder still can keep work.
