37. undue pressure of the valve plates against the valve seats A gate valve is sometimes installed in the suction line between a tank or pressure line and the pump sediment chamber It will shut off the supply source in order to clean the sediment chamber or to perform pump repairs If this valve is partially or fully closed it will interfere with the flow of water to the pump suction This may cause severe knocking and vibration of the pump because the water cannot flow into the cylinder cavities fast enough 17 3 A sediment chamber should be installed the suction line between the gate valve and the pump suction The strainers in the sediment chambers are sufficient to allow a free flow of liquid to the pump If the strainers become severely clogged they will completely stop the flow of liquid to the pump 4 Any plunger pump operating at a high pressure will not perform properly nor quietly if a mixture of air and water is allowed to enter the pump suction A small air leak in the suction line will cause the pump to knock and vibrate excessively by allowing the pump to draw a certain amount of water mixed with air on each stroke of the plunger A large air leak will cause the pump to lose prime after which it cannot be reprimed until the air leak is stopped Air leaks may occur at the joints of the suction line piping at the gate valve in the suction line at the gasket sealing the cap on the sediment chamber by a crack in the su
38. ure regulator operation It is also preferred to nozzle in excess of 50 of pump capacity to reduce the rate of erosion or wear on the regulating valve and seat When lower system capacity demands are required the pump speed should be reduced by changing drive ratios This will reflect savings in power consumption while reducing valve wear and extend pump life If line shock or water hammer is encountered a second surge arrester should be installed in the discharge line adjacent to the spray gun or nozzles Under some conditions it may also be desirable to isolate pump from piping with a suitable high pressure hose This will eliminate transmission of line vibration to the pump and minimize possible failure of piping pipe threads and pump casting Never pipe the bypass from a pressure regulating valve back into the pump suction When the discharge line is shut off the complete bypass is circulated back into the pump suction with a resulting rapid temperature rise which will destroy plunger cups and gaskets Avoid freezing by draining all water from pump and system in cold weather Make sure that the drive is adequate for the horsepower required and is properly aligned and tensioned With belt drives the pulley on both the motor and pump should be located as closely as possible to the bearing to reduce bearing and shaft bending loads Make sure that all bolts nuts set screws and keys are properly tightened and pump belts and pull
