1. Structural characteristics
PX series small flow high lift pump for horizontal, single stage, single suction, radial split volute pump. The pump is designed and manufactured in full accordance with GB5662 standard and API610 standard eighth edition.
The pump body of this series of pumps is a centerline supporting structure, with axial suction and radial discharge. The lubrication method of the bearing is thin oil lubrication, and the oil level is controlled by a constant oil cup to fully ensure that the bearing works in a good lubrication state.
The impeller is a closed impeller. Most of the axial force of PX series pumps is balanced by the method of impeller drilling balance holes, and the residual axial force is borne by the bearing.
Seal according to the use of different situations, you can use packing seal, single mechanical seal, double mechanical seal, series mechanical seal. The shaft seal box has a cooling or heating connection, and the seal is equipped with a cooling, flushing and sealing fluid system.
The pump special parts have only one pump body part, and the degree of three is high. When disassembling the pump, it is not necessary to disassemble the pump inlet and outlet pipelines and motor.
2. Performance parameters
Flow: 0.8 ~ 15m 3/h
Head: 12~125m
Working pressure: up to 2.5MPa
Working temperature:-80~450 ℃
3. Scope of application
Various temperatures and concentrations of sulfuric acid, nitric acid, hydrochloric acid and phosphoric acid and other inorganic acids, a variety of temperatures and concentrations of sodium hydroxide and sodium carbonate and other alkaline solutions, a variety of salt solution of various liquid petrochemical products, organic compounds and other corrosive raw materials.
Mainly used in: oil refinery, petrochemical, coal processing and low temperature engineering, chemical industry, paper, pulp and sugar industry, water supply plant, seawater desalination plant, power plant with heating and air conditioning system, environmental protection engineering, ship and marine industry, etc.
PB type shielded electric pump
PB type (basic type) use: suitable for conveying temperature is not more than 150 ℃, not easy to vaporize the cleaning medium. ● Performance parameters: flow rate: ≤ 500 m3/h head: ≤ 150m power: ≤ 315kW
The product change seal is static seal. The driven part of the coupling is located inside the machine body, the shaft does not need to extend out of the machine body, and the shaft sealing device is canceled. It has good buffer vibration absorption ability, compensates for the displacement change of the system, and improves the stress of the shaft system. Synchronous rotation within the rated torque, no friction parts, long service life; The special isolation sleeve design effectively reduces eddy current loss. When overloaded, the main driven shaft can slip in a short time, play the role.
Low cavitation margin magnetic pump
The magnetic pump is composed of a motor, a magnetic coupler, a centrifugal pump, a base and other components. Its working principle is to use a magnetic coupler to transmit power. When the motor drives the outer magnetic rotor of the magnetic coupler to rotate, the magnetic lines of force pass through the air gap and the isolation sleeve., Drive the inner magnetic rotor connected to the impeller to rotate synchronously, so as to realize the contactless transmission of power and convert the dynamic seal into a static seal. Since the pump shaft and the inner magnetic rotor are completely enclosed by the pump body and the isolation sleeve, the problems of "running, emitting, dripping, and leaking" can be solved, and the safety hazard of pump mechanical seal leakage can be eliminated.
PBX type (small flow high lift type)
PBX type (small flow and high lift type) ● Purpose: It is suitable for conveying cleaning media with temperature not more than 150 ℃, small flow and high lift demand. ● Performance parameters: flow rate: ≤ 12.5 m3/h head: ≤ 125m power: ≤ 45kW
PBZ type (self-absorption type) ● application: suitable for pumping cleaning medium with temperature not more than 150 ℃ from underground liquid tank. ● Performance parameters: flow rate: ≤ 50m 3/h head: ≤ 80m power: ≤ 45kW self-priming height: ≤ 6m
PBCG type (anhydrous cold ultra high temperature type)
PBCG type (anhydrous cold ultra-high temperature type) ● application: suitable for the transmission of high temperature cleaning medium below 400 ℃, without water cooling, high efficiency, energy saving and environmental protection. ● Performance parameters: flow rate: ≤ 500 m3/h head: ≤ 150m power: ≤ 220kW
