solution of practical work on the course "Pumps and com

The paper gives a solution of practical work on the course "Pumps and compressor units" Togu
Practical lesson №1
Task: Determine the degree of compression, polytropic efficiency, performance and power on the central clutch.
Initial data: TsN brand - GPA-Ts-6.3; shaft rotation frequency n = 8100 rpm; initial absolute compression pressure p1 = 4.2MPa; final absolute compression pressure p2 = 5.3 MPa; inlet gas temperature T1 = 288K; gas constant Rg = 490 J / (kg * K)
Practical lesson №2
Task: Determine the margin of stable operation of a centrifugal supercharger (gas density = 0.676 kg / m3).
Initial data: TsN brand - GPA-Ts-6.3; shaft rotation frequency n = 8100 rpm; initial absolute compression pressure p1 = 4.2MPa; final absolute compression pressure p2 = 5.3 MPa; inlet gas temperature t1 = 16.00С = 289К; commercial productivity Qк = 385000 m3 / h.
Practical lesson №3
Task: Determine the technical condition of the central nervous system.
Initial data: TsN brand - GPA-Ts-6.3; shaft rotation frequency n = 8100 rpm; initial absolute compression pressure p1 = 4.2MPa; final absolute compression pressure p2 = 5.3 MPa; inlet gas temperature t1 = 17.40 ° C = 290.4K; outlet gas temperature t2 = 36.20С = 309.4К; the methane content in the gas rmet = 0.93.
Practical lesson №4
Task: Determine the change in the internal relative efficiency of the central nervous system as a result of its repair.
Initial data: before repair, the CN worked at the following operating parameters: pressure at the inlet to the supercharger p1 = 4.7MPa, gas temperature at the inlet to the supercharger t1 = 18.50C = 291.5K; the pressure at the outlet of the supercharger 𝑝2 = 5.7 MPa, the temperature at the outlet of the supercharger 𝑡2 = 37.3 ° C. After the repair, the central heater began to work in the following mode: inlet pressure 𝑝1 = 4.6MPa, inlet temperature 𝑡1 = 16.5 ° C = 289.5K; outlet pressure 𝑝2 = 5.5MPa, outlet temperature 𝑡2 = 33.6 ° C.
