Cooling water flow control device and control method for lead-acid storage battery plate casting machine

Abstract

The invention discloses a cooling water flow control device of a lead-acid storage battery plate casting machine. A cooling water main pipe, cooling water branched pipes and flow control devices are arranged. The flow control device comprises a flow control body, an automatic adjusting device, a lower-limit flow positioning device and a shell. An automatic control switch is arranged in the flow control body. A displacement sensor in signal connection with the automatic control switch is arranged in the automatic adjusting device. A flow cavity is formed in the flow control body. The flow control body is arranged in the flow cavity and achieves automatic adjustment on flow through the automatic adjusting device. The lower-limit flow positioning device is arranged between the flow control body and the automatic adjusting device to achieve quantitative control over the minimum working flow of the cooling water flow. The invention further discloses a cooling water flow control method. Theflow control device automatically adjusts the cooling water flow according to changes of the indoor temperature. The minimum temperature difference between plate casting machines in a workshop is guaranteed. The consistency of a grid structure and a grid crystal form is realized.

Description

technical field [0001] The invention relates to the field of storage battery technology, and more specifically relates to a cooling water flow control device and a control method for a lead-acid storage battery casting machine. Background technique [0002] Lead alloys are used to cast grids, busbars, terminals and connecting bars of lead-acid batteries. Among them, the battery grid has two important functions: 1. As the "skeleton" of positive and negative active materials, it plays a role of mechanical support; 2. As the "blood system" of the plate, it plays the role of outputting and the effect of input current. Therefore, we have very high requirements for the grid produced: 1. It must have sufficient hardness and strength; 2. It must have good casting performance; 3. It must have good welding performance; 4. It must have high electrical conductivity, etc. Wait. However, in the process of grid casting, the temperature of the lead pot, the temperature of the lead spoon,...
