How to Install the discharge manifold and accessory manifold?

(1) Wash the contacting face between discharge manifold and cylinder blocks well, install the seal ring and put it onto cylinder blocks. The tightening torque of bolt M39×3 is 1954～2255N.m.

(2)As per discharge manifold requirement, install the accessory manifold (5-way or 4-way), discharge pulsation dampener, relief valve, bypass valve, and pressure release line etc. The tightening torques of bolts and nuts are required to meet clause 12.2.1.

The suction manifold is connected to 3 cylinder blocks simultaneously. It has three ports at left , middle and right. The drilling fluid can be sucked in from left, right or middle port according to your desire.

How to Install the suction manifold and suction desurger?

(1) Install the suction manifold: clean the flange end face of suction manifold,install seal rings and connect it to three cylinder block. The tightening torque of bolt M39×3 is 321～370N.m

(2) Install suction the suction desurger:install the suction desurger onto the suction manifold.

The discharge manifold is connected with 3 cylinder blocks simultaneously too. It has two ports at left and right side. The drilling fluid can be discharged from left side or right side.

The discharge filter shall be installed at the other side of discharge manifold. The discharging mud go to the drilling fluid line (manifold) after filtering.

Before the mud discharge manifold needs to be repaired, the bypass valve on pressure release line should be opened first, and let the pressure in discharge manifold to be released to zero.

Then install suction manifold and discharge manifold. After adjusting and aligning each part well, use a torque wrench to tighten the connection bolts between suction manifold, discharge manifold and cylinder blocks respectively to specified torque.

The fluid end mainly consists of cylinder block, liner, piston, valve, suction manifold, discharge manifold, discharge pulsation dampener, relief valve and spraying device etc.
