Problems solved by technology

With the increase of the size of the sand pump, the power of the motor increases, and the section of the wire increases. There is an urgent need for a terminal block and a junction box that are small in size, do not accumulate dew, and are very convenient to connect with large-section wires. However, such problems have not been solved so far.

Embodiment Construction

[0014] The following is a further description of the cemented carbide idling and series-connected amphibious sand pump of the present invention in conjunction with the accompanying drawings.

[0015] figure 1 , figure 2 , image 3 It is a schematic diagram of a group of low-voltage single-phase terminal blocks according to the first embodiment of the present invention. figure 2 Among them, the two ends of the main body 4 of the insulated terminal block have protective walls 1 with openings 2 for wires in the same opening direction. Outside the exposed outline of the metal conductor including the conductive stud 3 and the wire 6 and its connection terminal 8, there are respectively the straight wire 6 and its wire 6 extending from the main body 4 of the insulated terminal block 4 that will not deposit dew. Under the condition that the connecting terminal 8 is perpendicular to the conductive stud 3, it can still be smoothly connected to the protective wall 1 with the lead o...

Abstract

The invention relates to an amphibious hard-alloy mining vertical pump capable of running in idling or being in series-connection. U-shaped protective walls are arranged at two ends of an insulating connector of a submersible motor and disposed outside a metal conductor, extend out of an insulating body of the insulating connector and are provided with conductor wire opening. The insulating connector can be a single-phase connector used for each phase of conductor wires individually, or a three-phase integrated connector, and each end of the three-phase integrated connector is provided with three U-shaped protective walls. Opening directions of all the U-shaped protective walls are the same. The size of the connector is smaller than that of the conventional product, accumulation of dew is avoided, and advantages can be remarkable specially when large-section conductor wires are connected with the connector.

Description

technical field [0001] The invention relates to a cemented carbide sand pump that can be idling and can be connected in series for amphibious purposes, which is an amphibious water pump for both land and underwater use, and is suitable for a submersible sand pump or a land vertical pump for conveying liquid containing solid abrasive particles. . Background technique [0002] The existing technology, named "Vertical Pump for Mining", has three invention patents: ZL200410078876.4, ZL200410078879.8, ZL200410078880.0. [0003] At present, no technical solution has been found that the cable junction box and terminal block of the cemented carbide can be idling and can be connected in series with the amphibious sand pump and its submersible motor. With the increase of the size of the sand pump, the power of the motor increases, and the section of the wire increases. There is an urgent need for a terminal block and a junction box with a small size, no condensation, and a large cros...
