General requirements for pump foundations (1) The basic size of the heat conduction pump is usually determined according to the size of the pump base, and the distance from the base edge to the base edge is generally 100-120mm. The foundat

(1) sealing fluid system of packing seal (2) when the pump conveys clean liquid, the sealing liquid is led out from the pump outlet, and the pump can be led out from the middle stage, and connected with the sealing liquid inlet at the seal

Reverse oil pump characteristics reflect the pump in the oil pump working condition, hydraulic turbine (hydraulic turbine) working condition and braking (energy consumption) working condition of all the full characteristic curve, because o

Role of oil pump The function of the oil pump is to inject the right amount of fuel into the combustion chamber at the right time in the right form according to the working condition of the diesel engine to form a mixture suitable for comb

Technical requirements for gear shafts One: the main technical requirements of cold processing 1. Since the oil pump shaft transfers torque by the friction force of the two conical surfaces, in order to ensure sufficient contact area to tr

The oil pump The primary problem of oil pumps used as process pumps for conveying oil in refinery and petrochemical installations is performance degradation caused by liquid viscosity. Therefore, the most used is not easy to cause performa

The nature of the liquid pumped by the pump is very different, therefore, the type and structure of the pump is quite many, and these pumps play an important role in the chemical industry, petroleum, printing and dyeing, shipping, if the p

The purpose of the pump, in general, is to lift a required amount of liquid to a required height or to a place where required pressure is required. This required quantity, which corresponds to the flow rate of the pump, is usually expresse

Pump flow rate and diameter The flow record of the pump is determined by the flow rate required by the device and the number of pumps. On the flow and caliber of the relationship, used to use the diameter of the discharge outlet to express

It has long been known that liquids such as water and oil obey Newtons law of viscosity, which states that shear stress is proportional to sliding speed. In the past, oil pumps were used to transport these fluids, but with the rapid develo
