Petrochemical equipment is often 24-hour continuous operation, when the work pressure pump should be made much lower than the rated pressure, and speed work should also be lower than the rated speed.
石油化工设备常常是24小时连续运转，这时泵的工作压力应该取得比额定压力低得多，且工作转速也应该低于额定转速。
This machine adopts hydraulic transmission, using ST foreign standards, thus ensuring the continuous operation seal not abate oil cylinder pressure and durable.
该机采用液压传动，使用ST国外标准密封件，从而保证连续运转时不减弱油缸压力，经久耐用。
