2. Design features
2.1 The power end
2.1.1  The pump frame is of welded steel – plate construction. The bearing housings of the crankshaft and the transmission shaft are made of steel castings and are welded to the frame after rough – machined. They are stress – relieved after welded.
2.1.2  The crankshaft is a hollow steel casting.
2.1.3  The herringbone gear ring and pinion are composed of helical gears in pairs
respectively.
2.1.4  The crosshead is a one – piece casting and runs directly in the guides.
2.1.5  All the bearings, crossheads and guides are splash – lubricated. At suitable locations there are oil wipers and troughs provided to ensure a well – distributed lubrication.
2.1.6  The transmission shaft is equipped with single – row radial short – roller bearings.
2.1.7  The main bearings are double – row radial spherical – roller bearings.
2.1.8  The crosshead is equipped with long – roller bearings.
2.1.9  The big end of the connecting rod runs in radial roller bearing.
2.2 The fluid end
2.2.1  The fluid end is composed of three fluid modules (cylinders), each of which is a
sectional and communicating construction. The suction and discharge are
accomplished by suction and discharge pipes. The suction and discharge valves are
vertically aligned with each other to minimize the volumetric clearance.
2.2.2  There is clamp connection between the piston rod and the intermediate rod, which facilitates the services of these parts.
2.2.3  The piston liner is attached to the liner seat with a buttress – threaded retainer.
2.2.4  The threaded cover of the valve box is attached to the threaded ring with buttress threads, which facilitates the services of them. The threaded ring is fastened to the fluid module with studs, which facilitates the machining and servicing of the fluid
module.
2.2.5  The taper of the valve seat is 1:6. The bottom of the seat is provided with a shoulder to be suitable for high operating pressure
2.2.6  The piston rod conforms to SY5138-86. The piston is fastened with M39x3 locknut and is lubricated and cooled by the water or the water with inhibitor supplied by a centrifugal spray pump.
2.2.7  There are six sizes of liners with an increment of 10mm in I.D. All these liners are the same in O.D.
2.2.8  There are two types of liners: high-grade liner and plain liner. The high – grade liner is made of carbon steel as a base metal which is casted or inserted with high – chrome alloy – steel to ensure wearability. The plain liner is made of low – carbon steel which is carburized and quenched inside to enhance the surface hardness.
2.2.9  There are suction inlets in front of and on both sides of the pump, which are connected to the suction manifold. The three suction flanges are of 12”ASAB16.5-150PSI or 10”ASAB16.5-150PSI.
2.2.10 The flanges of discharge pipe and five-way joint are of 4”API-5000PSI6B. The seal rings here are API’s R39.
2.2.11  The discharge pulsation dampener is spherical and pre – pressured. Its Max. working pressure is 350kg/cm2, and volume is 75 litres (20 gallons). The pulsation dampener is connected to the air filler and to the pressure gauge, using 3/4” – 14NPT and 1/4” – 18NPT respectively.
2.2.12 The suction pulsation dampener is of rubber – hose type and pre – pressured and connected with the flanges of the 12” and 10”ASAB16.5-150PSI.
2.2.13 It is advisable to equip a charging pump during operation to improve the suction performance and raise the efficiency of the slush pump.
2.2.14  It is advisable to equip a spray pump during operation to cool the pistons and liners so as to extend their service life.
2.3 Accessories
Complete set of special tools for major locations of the pump will be provided along with the slush pump to facilitate the services and replacement of expendable parts.
3. Installation
Prior to installation, a proper layout plan shall be prepared to indicate the position of the slush pump, charging pump and spray pump as well as the disposition of the suction and discharge manifolds.
The slush pump shall be provided with a centrifugal charging pump to enhance the pump efficiency. There shall be a metallic slush sump above the ground, and the suction manifold shall be as short as possible to improve the suction condition.
3.1 Foundation
The slush pump shall be set on a level concrete foundation and the same oil level shall be kept in the left and right oil troughs of the power end so as to assure satisfactory
distribution of oil to all parts to be lubricated. Especially in drilling vessels, the slush pump shall be properly leveled over the whole length. With the slush pump leveled, all the anchor bolts shall be tightened uniformly around the main base to secure the pump base against deformation, especially in case of belt or chain transmission, and some plates or bars may be used to fix the pump and prevent the pump from displacement.
3.2 Transmissions
A belt or chain transmission can be used for the slush pump. According to the actual
conditions the driven sheave or sprocket can be located on the left or right side, and the sheave to drive the spray and charging pumps will be mounted on the other side. The rotation direction of running centrifugal spray pump or charging pump shall be the same as the designated directions for both spray and charging pumps otherwise it cannot be normally operated. The slush pump should be operated at a low speed to improve the suction condition, realize a smooth operation and prolong the service life of the expendable parts.
The spray pump or charging pump can be driven directly by an electric motor in proper
direction.
3.3 The suction manifold
The ID of suction piping shall be at least as large as the inlet ID of the pump. Prior to
installation, the suction manifold shall be thoroughly cleaned from inside. After installation, no leakage should be allowed at any connections. It is advisable to use as few valves or bends as possible. Always use full-opening valves, such as butterfly valves, and never use flow-limiting valve which may reduce the efficiency of the pump.
The slush pump should be provided with a charging pump to realize a smooth operation of the pump and extend the service life of expendable parts.
The suction manifold shall be designed to be suitable for “dual” operation, permitting
either “natural” suction or “charged” suction. The piping used for “natural” suction shall be as short as possible and preferably without bends. A suction pulsation dampener (desurger) should be connected with suction piping at either type of suction and shall be mounted as close as possible to the pump inlet.
There shall be a safety valve between the pump inlet and the outlet of the charging pump.
The safety valve shall be adjusted to 5kg/cm2 (70psi). It protects the charging pump from damage in the event of overpressure occurring in the suction manifold.
3.4 The discharge manifold
According to the field conditions, the discharge manifold can be installed on either the left or the right side of the pump. The inside diameter of the manifold is 100mm (4”).
A pressure relief valve shall be mounted near the discharge port of the pump to protect
the pump against damage from overpressure. The valve shall be located ahead of any
valve on the discharge manifold. In such a case, any unexpected starting of the pump in the event of closed valve will not damage to the pump. The discharge piping of relief
valve shall be fastened securely and extended safely into the slush sump to avoid any
accident resulting from high-pressure slush with the relief valve opened.
A pulsation dampener is mounted on the discharge manifold to reduce the fluctuation of the pressure of discharged fluid.
