BW70-8 DualLliquid Injection Pump

The BW70/8 double cylinder mortar pump is mainly composed of an electric motor, pump body, base, pump head, air chamber, pressure gauge, cleaning valve, pulley drive, and other parts. The power generated by the electric motor is transmitted to the pump body through a belt, and through the rotational motion of the crankshaft connecting rod, it becomes the linear reciprocating motion of the piston, thereby controlling the opening and closing of the steel ball in the pump head for suction and discharge of slurry.
The pump body is composed of two parts: a power device and a hydraulic device. The power device includes a crankshaft, connecting rod, crosshead, crosshead pin, input shaft, transmission gear, etc. The crankshaft structure is designed reasonably, the manufacturing process is advanced, and it has been quenched and tempered, making it durable. This device also incorporates a bearing type connecting rod structure, which has the characteristics of stable transmission, low noise, good wear resistance and vibration reduction performance, and long service life; The hydraulic device mainly consists of cylinder liner, piston, piston seat, piston rod, piston pressure pad, pump head, and other parts. The piston rod and piston seat are sealed with a 10 ° conical seal, and the piston is tightened with an M14 × 1.5 internal thread connection method, effectively preventing mud infiltration. Folding is more convenient and fast. The piston is made of imported polyether material and has a reverse lip structure, with good concentricity, greatly improving the continuous grouting operation time and reducing the operator's operating cost.
The lubrication of the pump body (crankcase) mainly adopts splash lubrication method, which drives the lubricating oil to splash around through the circular movement of the crankshaft, connecting rod, and gear to achieve lubrication purposes. The amount of lubricating oil in the solid box should not be too small, and the lubricating oil level should be regularly maintained to the oil level hole. Before starting the pump, check whether the pump body and gearbox have been filled with lubricating oil and the amount of oil added to ensure sufficient lubrication. The type and amount of lubricating oil to be added. The top of the pump body is equipped with a refueling and exhaust bolt. Unscrew this bolt to add gear oil to the box and have an exhaust function. The back of the box is equipped with an oil level bolt and an oil discharge bolt. The height of the lubricating oil in the box should reach the end plane of the oil gauge bolt. When replacing the lubricating oil, the oil bolt can be loosened.
