What should be paid attention to in the installation of spray pump

Spray Pump is a kind of equipment especially matched for mud pump for oil drilling, with the function of flushing and cooling sleeve and pistons in the process of pump operation, as well as include the other situation for transportation mud. Pay attention to the following points when installing the spray pump:

（1）Pump installation
Installation location of pump shall be as near to the pumping source as possible, to shorten length of the suction section and reduce suction loss. Pump installation shall be horizontal, firm, reliable and vibration-prevention.

（2）Installation of shaft coupling(for motor straight unite drive)
Service life of pump and motor depends on alignment of elastic shaft coupling, installation error with pump and motor shaft require to parallel limit offset no more than 0.25mm axes corner meet error no more than 0.12mm. If inspect result mistake, adjust degree of tightness of pump and motor’s install bolt or tray iron, to put up axes tune. When square with frank rule process inspect to reach require.

（3）Strap wheel installation
Two strap wheel axle should parallel, and no more than 2mm with end error; strap must alignment, degree of tightness equal; motor shall be balanced and locked-in.

（4）Installation of pipeline
A. Inlet pipeline section area must larger than pump sever area, or equal to pump sever area.
B. Suction pipeline shall not be fitted with any throttle valve but can be equipped with a normal open valve to minimize disorder of fluid flow, which may be closed only when the pump is disassembled for inspection/repair.

C. In order to prevent bubble in suction pipeline, gradual transition from high altitude to low altitude shall be available between the pumping source and the pump. If the user needs to use the pump under the condition that there is a suction height, please use a vacuum pump or a bottom valve for water drawing.

D. Pipeline at pump inlet must be horizontal and straight, with a length of at least twice as diameter of the suction pipeline.

E. When temporarily using a hosepipe for suction pipeline, ensure that the hosepipe will not be compressed, because pressure in the suction pipeline is generally lower than the atmospheric pressure. If the hosepipe is compressed, as it is affected by the atmospheric pressure, flow will be reduced and even intercepted.

F. Outlet pipeline shall be fitted with a normal open valve, which is convenient for inspection/repair.

G. Each pipeline (including inlet pipeline) must be with its own support. It is strictly forbidden to let a pump bear weight of any pipeline.

H. When operation condition is unclear or unstable, outlet pipeline must be equipped with a throttle valve, to ensure that pump operates at the design point.
