Electric vacuum pump water diversion system for pump

Abstract

The invention relates to an electric vacuum pump water diversion system for a pump, and solves the problems that a piston water diversion pump is relatively large and is not universal, and a matched valve of the vacuum pump is complex in operation, high in cost, easy to break down, small in application range and influences use equipment in water inlet starting of an existing centrifugal pump. Thesystem comprises a vacuum pump, a motor, an air suction valve and a lubricating oil tank, the motor is connected with the vacuum pump and drives the vacuum pump to work, and an outlet of the vacuum pump is connected with the air suction valve through a pipeline, and the lubricating oil tank provides lubricating oil for the vacuum pump via a pipeline. The electric vacuum pump water diversion systemhas the advantages of being rapid in self-priming, reliable in operation, compact in structure, small in size, low in weight, easy to maintain, long in service life and the like.

Description

technical field [0001] The invention relates to a pump water diversion system, in particular to an electric vacuum pump water diversion system for a pump. Background technique [0002] At present, centrifugal pumps generally need to be started by water intake. The water intake of most centrifugal pumps is realized by piston water pumps. However, piston water pumps need to obtain power from the gearbox, and their volume is large, so special design is required. , it can be used in conjunction with the gearbox, so this method is not universal. [0003] The centrifugal pump can also be started by vacuuming the vacuum pump to achieve water intake. The valves used with the vacuum pump are generally solenoid valves, pneumatic valves or manual valves. If the matching valve is a solenoid valve, the solenoid valve needs to be equipped with a power supply, sensor or pressure switch, and a control system needs to be set up when the sensor is used. When the pressure switch is used, bef...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of the large size of the piston water diversion pump and the lack of versatility in the start-up of the existing centrifugal pump, the cumbersome operation of the matching valve of the vacuum pump, high cost, prone to failure, small range of use and damage to the equipment used. Influenced by the problem, provide an electric vacuum pump water diversion system for pumps, the electric vacuum pump water diversion system for pumps is simple in structure, easy to use, and strong in practicability
