Noise analysis of high pressure pump and its operation method

High pressure pump is high pressure rotary jet grouting to provide high-pressure power equipment, has been widely used in construction, roads, pipe dredging and other facilities, but the use of high-pressure pump, high-pressure pump gear often appear Noise, then high-pressure pump gear noise causes and how to solve the problem of noise, Xiao Bian today for everyone to interpret. High-pressure pump noise analysis and operation method First, the high-pressure pump gear noise has the following possible aspects: (1) rotary vane impact on the cylinder body, high-pressure gear pump residual volume and exhaust in the dead space of the sound pressure oil; (2) the impact of the exhaust valve plate on the valve seat and support member; (3) the echo and bubble burst sound in the housing; (4) the bearing noise; (5) the noise caused by a large amount of gas and oil impacting the oil deflector; (6) other. Such as transmission caused by noise, air-cooled gear pump fan noise and so on. (7) Motor noise, which is a crucial factor. Second, to solve the problem of high-pressure pump specific operating methods (A) for self-priming high-pressure pump should be placed in a well ventilated place to run, in order to facilitate rapid cooling, reduce the motor temperature. Otherwise, prolonged operation, easy to burn the motor. If a farmer in the use of self-priming high-pressure pump, the plastic film covered on the motor is not removed, causing the motor overheating, burned the coil. In addition, before starting, be sure to check the high pressure pump body of water, otherwise, not only affect the self-priming performance, but also easy to burn shaft seal components. Under normal circumstances, the high-pressure pump should start 3 to 5 minutes after the water, or should immediately stop checking. (B) high-pressure pump maintenance When high-pressure pump failure, should not disassemble yourself. Because of their demolition, I do not know where the fault is caused by blindly dismantling a pass; Second, there is no special tools and often damage the original parts intact. The best way is to have experienced, large-scale maintenance point of repair, and timely replacement of over-age parts and some wearing parts. Under normal circumstances, high-pressure pump should be repaired once every six months, to eliminate sick work. (C) non-use period stored in the non-use period, the high-pressure pump should be promptly removed from the water, and emptying high-pressure pump water, especially in the cold winter. Then place it in a dry place, qualified users can also apply the butter in the key parts of the high-pressure pump, lubricating oil in the bearings to prevent corrosion of parts. In addition, the non-use of high-pressure pump, not the longer the better. If you do not use for a long time, not only easy to rust parts, but also reduce the life of high-pressure pump. (D) to determine the number of high-pressure pump and standby rate: for the normal operation of high-pressure pump, usually only one, because a large high-pressure pump and work in parallel with two small high-pressure pump, High-pressure pump efficiency is higher than the small high-pressure pump, so from the perspective of energy-saving rather choose a large high-pressure pump, rather than two small high-pressure pump, but in the following cases, consider two high-pressure pump parallel cooperation: Taiwan high pressure pump can not reach this flow.
