Before installation and operation, the operator should read this manual carefully, and do installation, operation and maintenance according to the instructions in manual. If you do not know the related contents, improper installation, operation or servicing may cause human injury or/ and the equipment damage.

l The operator should read this manual carefully before operating the drilling pump. He can operate or maintain the equipment only when he knows well the functions and operation or maintenance of the equipment.

The housing is a box type weldment of steel plates, after stress relief treatment, rough and finish machining, the housing is formed. It is the base part of drilling pump. All components of drilling pump are installed into it. Oil sump and lubrication oil pipeline are set inside the housing to supply lubrication oil for gear, bearing, crosshead etc. A small lifting device with capacity of 500 kg is installed on housing for lifting liner. 4.1.2 Pinion shaft assembly

The unitized drilling pump includes drilling pump, drive and transmission device, mud charging system, high pressure mud release manifold and big skid.

At a port of the connecting line between the accessory manifold and the relief valve, we connect a bypass line with a valve to the pressure release line (which go back to suction tank) of relief valve, therefore, when we open the valve on the bypass line, the mud pressure can be released from the discharge manifold before disconnecting it for servicing.

Liner spraying device is consisted of spray pump, water tank, spraying manifold etc. Its function is to wash, lubricate and cool liner and piston during mud pump running in order to prolong the service life of liner and piston. The spraying pipe position is shown in Fig. 7.

Safety warning：For any preserved pump, no matter being used at well site or transported from factory, it is necessary to be checked before put into operation. Make sure every part of pump is available and in good condition.

The unitized drilling pump directly driven by diesel engine mainly includes drilling pump, diesel engine, cardan shaft ,V belt drive device etc. the diesel engine can also directly drive V belt transmission device to run drilling pump. The mud charging system is installed alone. The high pressure mud release manifold is connected to drainage port of relief valve and mud is released into mud suction tank.

The drilling pump mainly consists of two portion, power end and fluid end (see Fig. 1). The power end includes pinion shaft, crankshaft, connecting rod, crosshead sliding block device. It can supply power to fluid end and change the rotary motion to reciprocating motion. With the power from the power end, the piston of

For installation and aligning etc of transmission device between pump and power supply, please see the related chapters of operation manual of unitized drilling pump. The following is just for reference.

（1）Release pressure：before doing maintenance work at cylinders, liners, pitons or valves, close the valves on suction line and discharge line, open the bypass valve to mud tank ( see Fig. 17, item 2). Only in this way can the pressure in cylinders be released, and avoid danger at opening valve pot cover and dismantling liner.

The left and right sides of this pump are determined by looking from the power end to the fluid end. This way is also used for determining the left, middle and right sides of equipments such as crosshead, cylinder etc.

Install the pump on the structural member base of drilling boat or drilling platform. Shown in Fig.13 and 14, when fix pump skid with bolts, it is a must to place mats under skid for avoiding any distortion and deflection resulted to power end frame. Note, it needs full padding of pump skid before tightening skid for avoiding extra stress resulted to pump when tightening bolts. The mat’s width is required to be not less than the width of runner flange of skid. Its length is not less than 12″ （305mm）. When integral installation is adopted for power unit or electric motor to pump skid, the pump must be fixed on the skid of the t-beam with retention blocks rather than bolts. In this way, the drilling pump could be a bit “float” so as to reduce the possible deformation of the pump frame caused by the deformation of barge deck or platform.

This manual generally describes the technical specifications and performance parameters, drive principle, configuration, installation and adjustment, operation and maintenance, frequent failure and troubleshooting, replacement of consumable and other operational precautions etc.

HHF-1300/1600 drilling pump is a horizontal, triplex, single action piston pump. As an important equipment for drilling operation, it feeds and circulates the high-pressure drilling fluid, which flushes the well bottom and crushes rocks, cools and lubricates drill- bit, and then carries cuttings (rock chips) return to the surface.

Safety warning：When any of mechanical and electric parts of drilling pump are running, all safety device should be in normal and effective status, include protection of AC VF motor for cooling blower faults accidently, pressure alarm of lubrication system, motor power-off protection of mud charging system. The matching between the relief valve’s limiting pressure and liner diameter, the discharge dampener inflating pressure and the related requirements etc should be checked and confirmed every shift.

10.1.2.2 The liner spray pump can be started in advance or together with drilling pump. It is forbidden to start drilling pump earlier than spray pump starting at any time. For spraying lubrication of liner and piston, spraying system should adopt different coolants under different drilling conditions. Note: if water is the basic fluid content for coolants, preservatives （such as emulsified oil or motor oil）should be added in it for corrosion protection of parts.

There is a recommended spare parts list attached to this manual for part ordering reference, if the needed parts exceed the items listed, please consult the parts list of HHF-1300/1600.

The lubrication oil pump has two installation modes of “Built-in mode” and “outside mode” for user to choose. If the user does not request specially, the mode “built-in” shall be used generally, no matter what mode adopted, the internal lubrication piping is same.

10.1.3.2 Natural suction operation－when the pump is running under natural suction condition, the pump speed is limited by the filling degree of pump. If some mental knocking sound can be heard from the fluid end while running，it means that pump has been cavitated and not fully- filled. At this moment, the charging pump should be started until the knocking sound disappeared and operation turn to normal, then the natural suction can be adopted again.

HHF-1300/1600 drilling pump is one of the most important equipments for rig for middle and deep depth well drilling. The parts and components of this drilling pump are designed and manufactured according to API 7K and relevant standards. It can satisfy the technological requirements for well drilling.

10.1.3.4 The pressure of mud discharge pressure gauge should be watched very carefully at pump starting. Before the mud return to ground, the operator is not allowed to leave.

The drilling pump’s pressure lubrication system is shown in Fig. 9. In this system，through the connector holder II, the oil pump sends oil to pinion shaft nozzle, main bearing oil pipe and crosshead chamber connector holder I，then through connector seat I distribute oil to crosshead, crosshead bearing and crosshead extension rod.

The drilling pump can adopt natural suction or charging suction. The pipeline for natural suction should be short and the shorter the better. It is the best that it has no elbow. The size of pipeline should be the same as that of pump suction port at least （ it should be bigger if it is longer than 6 feet）. The pipelines for charging suction can be made to be any bending shape needed. And the charging pump should have bypass pipeline. The drilling pump can keep working in a natural suction way once the charging pump fails or is in servicing.
