Title: Number of pump control method
Inventor: MURATA TAKUMI
IPC: E03B5/00
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of water supply pressure generated right before additional driving by difference in actual Q-H characteristics inherent in a pump itself by performing the pump additional driving at a time when it reaches the water supply quantity obtained by subtracting overall allowance totaling respective flow control allowances under driving at present together. SOLUTION: In controlling the driving number of a plurality of water feed and supply pumps installed in a water feed and supply station, an additional driving changing from a single driving to two pumps driving is performed, when the water feed and supply quantity reaches a value (Q1-ΔQ1) obtained by subtracting a difference quantity ΔQ1, a difference between a characteristic curve inherent in the first pump, or a characteristic curve by pump secular change and a typical characteristic curve (1) from the water feed and supply flow rate Q1 corresponding to a constant water feed and supply pressure on the typical characteristic curve (1), when the first pump is driven at rating rotation speed.  The additional driving from two-pump driving to the three-pump driving is so controlled to perform similarly when the water feeding and supply quantity reaches (Q2-ΔQ2) from the water feed and supply flow Q2.

C, Si, Mn, Al and Mo and/or V respectively at prescribed proportions to direct hardening treatment. CONSTITUTION:A seamless steel pipe contg. by wt% 0.03-0.15% C, 0.01- 0.80% Si, 0.50-2.00% Mn, and 0.001-0.10% A, and contg. 0.01-0.30% Mo and/or 0.005-0.10% V is prepared. Further, this steel pipe has the composition of <=0.21% Pcm value expressed by the equation. Thence, this seamless steel pipe is directly hardened immediately after hot rolling; thereafter, it is tempered at the temp. above 600 deg.C and below the Ac1 transformation point. As a result, the Pcm value which is the index for hydrogen crack sensitivity at the welding of the steel pipe is reduced remarkably; therefore, on-site weldability is excellent, and in spite of the decreased C content in the components, the strength extremely higher than that of conventional steel pipes is obtained at a middle temp. region around 350 deg.C.
