BP25/8J roadheader spray pump
A, product introduction:
BP25/8J roadheader spray pump is designed for roadheader spray, mainly is suitable for the S100 - 200 series boring machine, ELMB75 series, EBZ series roadheader tunnelling machine and EBJ series of various types of tunnel boring machine.
BP25/8J roadheader spray pump adopts complete delivery, mainly by the airborne spray pump (hereinafter referred to as the high-pressure pump), form a pipeline filter, negative pressure dust removing device, according to the tunneling machine models of different, airborne spray pump motor drive and hydraulic drive two structure forms, this manual applies to motor driving structure.
Has the following characteristics:
Positive pressure water supply pump using airborne spray, without transferring water tank, the reasonable location can be directly installed on the machine body, airborne spray pump water from the boring machine cooling water or static water;
The airborne spray pump safety valve by setting safety valve and adjustable safety valve, safety;
The water inlet filter with the spray system can ensure that the spray water filtration, to prevent impurities entering the high-pressure pump and spray system;
According to the specific conditions of dust negative pressure dust removing device design of boring machine can produce effective control of boring machine operation in the process of.
Two, the work principle and structure feature
Roadheader spray pump consists of a pump body and a hydraulic motor, system of BP25/8J roadheader pump with high pressure oil boring machine itself walking hydraulic system driven by hydraulic motor as power, high-pressure pump works, will supply high pressure pump low pressure water into high-pressure water through a L set of spray water system, by high pressure spray atomization atomization spray to flow into high dust source, realize the effective control of dust.
