Embodiment Construction

[0012] For a 25m 3 / h differential pressure copper pump, equipped with two 15 kW low-pressure feeding pumps of the same specification. Two low-pressure feed pumps are connected in parallel. When the 1# low-pressure feeding pump is running, the 2# low-pressure feeding pump is used as a backup. When the 1# low-pressure feeding pump fails and needs to be repaired, the 2# low-pressure feeding backup pump is used, which not only facilitates the maintenance of the low-pressure feeding pump, but also ensures the long-term stable operation of the differential pressure copper pump. At the same time, the price of a low-pressure feed pump is 20,000 yuan and the power is 15 kilowatts, while an electric high-pressure copper pump costs 300,000 yuan and the power is 155 kilowatts. Therefore, adding a low-pressure feed pump is more expensive than using an electric high-voltage copper pump. The pump saves investment and power consumption.

Abstract

The invention discloses a method which leads the differential pressure copper pump to run stably for a long period. Two and more than two low pressure feeding pumps are arranged on the invention, wherein, one or a plurality of low pressure feeding pumps run, and one or a plurality of low pressure feeding pumps are spare. The spare pump(s) is (are) used when one or a plurality of low pressure feeding pumps are broken down. The invention has the advantages that the maintenance is convenient, the differential pressure copper pump runs stably for a long period, the investment is reduced, the power consumption is saved and the technology is reasonable.

Description

technical field [0001] The invention relates to a method for long-period stable operation of a differential pressure copper pump in the production and refining process of synthetic ammonia. Background technique [0002] The differential pressure vertical copper pump is a kind of operating equipment used to recover the energy of high-pressure cuproammonia liquid and transport liquid. It is composed of several parts such as the pump and the microcomputer electric control box. The booster cylinder consists of two vertical, parallel hydraulic cylinders, the main function of which is boosting and pumping fluid. The commutator is used to control the high-pressure waste copper liquid to alternately enter the lower chamber of the two booster cylinders to realize the reciprocating motion of the pistons of the two booster cylinders. The flow distributor is used to control the entry and discharge of new copper liquid in the upper chamber of the pressurized cylinder (filling and pumpi...
