Hydraulic Suspension Transformer Oil Pump Product Overview The shell of hydraulic suspension pump is composed of motor shell, pump body, components of junction box and sealing ring.The protection class of the whole pump can be up to IP67.The inner part of the oil pump is composed of the rotor, hollow shaft, impeller and wear-resistant sleeve, which becomes a rotating part. Two hydraulic suspension devices are set at both ends of the hollow shaft as support and bearing. The stator windings are fixed between rotor and motor shell with a lead wire connect to the junction box to connect to the outer power and ground wire. The hollow structure is applied to the oil pump motor shaft to enhance the lubrication and heat dissipation of the hydraulic suspension. The pressure relief hole is designed to reduce the axial force of the impeller. Based on these special process,the reliability of oil pump is enhanced and the noise that caused by vibration is lowered. Advantages 1.Low noise; 2.High reliability; 3.Low vibration. Application The product is suitable for burial transformer with requirement of low noise and high reliability.
