Main oil pump: military brand constant power variable piston pump or Kawasaki main oil pump is adopted. Constant power control can effectively prevent motor overload and bear higher pressure and load than conventional gear pump.
Chassis: It adopts engineering four-wheel drive chassis with reliable quality and convenient maintenance.
Electric control system: the main electrical appliances are Schneider, LS brand, Zhengtai, etc., equipped with a screen, the parameters are easy to observe, and can be pumped in an emergency, which is more convenient to control the commutation time.
Centralized lubrication system: a plunger pump injects lubricant into the main pipeline and lubricates the lubrication points through the distributor. "Point-to-point" lubrication protects key components from wear.
S-tube valve: it is made of high manganese steel by integral casting, and the easy-to-wear surface is surfacing with anti-wear materials, which has the advantages of high pressure resistance and wear resistance; The transition of the inner cavity is smooth, the concrete flows smoothly in it, and the pumping performance is further improved; The spline shaft adopts alloy material for special surface treatment, which improves the wear resistance and fatigue strength.
