A hydraulic profile control and plugging water pump oil tank with a heat dissipation system, relates to a hydraulic driven profile control and plugging water injection equipment for oil and water well operations, comprising an oil tank body, an intelligent temperature control instrument, a return oil filter, a temperature sensor, an oil heater, an air cooler, and a one-way valve.
The air cooler is located on the main body of the oil tank, and the oil return pipe of the oil tank is respectively connected to the inlet of the one-way valve and the inlet of the air cooler. The outlet of the one-way valve is connected to the main body of the oil tank through a pipeline, and the outlet of the air cooler is connected to the oil return filter located on the main body of the oil tank through a pipeline. The oil return filter is connected to the main body of the oil tank, and the temperature sensor, oil heater, and air cooler are respectively connected to the intelligent temperature control instrument through wires.
Petroleum machinery and equipmentIt belongs to the field of pumping equipment for oilfield operations, and is an electro-hydraulic reversing device for hydraulic profile control injection pumps. It mainly includes mud rods, hydraulic cylinder piston rods, travel switches, electro-hydraulic reversing valves, travel switch fixing brackets and control circuits, as well as a reversing valve base. An electro-hydraulic reversing valve is fixedly installed on the reversing valve base, and a throttle valve is also added between the reversing valve body and the pilot electromagnetic reversing valve;
It also includes a travel switch installed on the travel switch bracket and in contact with the regulating back nut during the reciprocating operation of the hydraulic cylinder piston rod; The control circuit has been changed from the original circuit board and proximity switch control to the current relay and travel switch control, with the addition of two diodes. The present invention is equipped with a throttle valve to reduce the impact on the oil circuit during commutation
