Pump industry suppliers to tell you: keep the screw pump, gear pump pumping high yield rate

keep the screw pump, gear pump pumping technology of high resolution

world general mechanical recovery method is the sucker rod of screw pump, gear pump, and its common course topic is pump can not be full of, cause the low yield, not full because of the pump capacity is greater than the yield of Wells or water pump suction inlet gas separation, one department pump displacement suffer indignities interference and loss, if to eliminate the influence of pump in the gas and control the running time of the pump, the pump displacement match the amount of fluid flow into the bottom hole, can advance the efficiency and reduce the capital. Keep the screw pump oil productivity of detailed practices are as follows:

1, the indicator meter measuring pump is full percentage coefficient, application of integrated data acquisition system can the motor power and indicator data obtained at the same time. Indicator diagram, one of the main purpose of the application to produce liquid level measurement combined with indicator diagram can know well whether with big production yield, liquid column height is higher than the pump suction import depth, pump is not full and free gas is upward along the casing annulus migration.

2, should carry on the acoustic liquid level measurement, determine the production level and relative depth of the screw pump suction imports. If the liquid level above the pump suction imports, as well it is not possible to big mining production. If the gas interference affect production rate, the liquid level above the pump suction imports, if it is a large amount of smoke leads to low productivity, the liquid level should be in the pump suction inlet or around.

3, diagnosis low efficiency Wells, method for diagnosis of screw pump is to determine the total efficiency of pumping system, and only measurement input the original idea to determine the overall efficiency of power, and the fruit of the determination of bottom hole producing pressure and accurate test data.

4, downhole gas separation. Invalid pump operation is often caused by the gas, through acoustic liquid level measurement and indicator diagram for diagnosis. Is would import in pump suction fluid into the layer below, if placed above the gas separator should be used. If the seat sub arrangement in the following at the bottom of the fluid into the layer, can occur in the ring air effective gas separation, casing external separator's role at this time.

5, control pump capacity, and can be controlled by adjusting the four parameters: plunger size, length of stroke, pump speed, daily running time. By pulling out equipment capability, usually do not change the size differences of pump. Simple way is to change the ground equipment configuration, such as moving beam bars to change the ground and pump stroke length.

pump industry suppliers is the collection scientific research, design, production, management, services for the integration of production enterprises, the products are widely used in petroleum, chemical industry, metallurgy, electric power, mining, coking, medicine, printing and dyeing, food, paper making, environmental protection and other fields. The company has a modern self-priming pump performance testing means, equipment is excellent. Main production ZA, ZAO, ZE petrochemical pump, screw pump, CZ chemical process pump, IH chemical pump, forced circulation pump, SPP chemical mixed-flow pump of 28 kinds of material, 30 series more than 1000 specifications special alloy chemical pumps, valves, stainless steel pipe, fluorine pipe parts.
