When the motor directly connected feed pump starts, the pump speed rises from zero to rated speed in a short time, and there is no means to control the speed. Especially in the early stage of boiler ignition, the feed water flow is small,

In the process of use, it is inevitable to repair and maintain the heat conduction oil pump. The following points are introduced: Disassembly and discharge sequence of heat conduction oil pump (1) Unscrew the bolts on the outlet side beari

Pump bearing heating causes and treatment methods are as follows: (1) The scraping and grinding of bearing tiles is not required. The treatment is to repair the bearing tile or replace it. (2) For gear oil pump bearing clearance is too sma

First, talk about the general steps of diesel pump disassembly (1) unscrew the oil discharge plug on the suspension body, put out the lubricating oil, and remove the motor. (2) loosen the connecting bolt of the pump body and the bearing bo

internal high viscosity rotor pump is a kind of special pump that can transport high viscosity materials, because of its outstanding contribution to the transmission of high viscosity medium is usually called high viscosity pump; Its advan

Application of centrifugal pump industrial engineering (1) Solid particle liquid transportation In industrial engineering, the fluid machinery with liquid to transport solid particles is called solid-liquid two-phase flow pump, also known

Pump can not start or start load is large Reasons and treatment methods are as follows: (1) The prime mover or power supply is abnormal. Treatment is to check the power supply and prime mover situation. (2) The pump is stuck. The processin

Under normal circumstances, the heat transfer medium to the heat conduction oil pump cover and bearing, by the pump cover and the bearing seat surface heat dissipation, so that the temperature of the bearing seat to adapt to the temperatur

CYZ self-priming centrifugal oil pump working principle: 1. The installation height of the pump shall not exceed the allowable suction height. 2, the pump has no safety valve, it is recommended to set a safety valve in the oil discharge pi

(1) Based on temperature, cold oil pump below 200℃, hot oil pump above (200.4000C); (2) to distinguish between sealing oil, general hot oil pump sealing oil, and cold oil pump not. (3) To distinguish by material, hot oil pump to carbon st
