1. Structural characteristics
(I) bearing components
★The radial thrust ball bearing with the non-driving end is designed in combination with the radial bearing, and the radial bearing at the driving end is designed to ensure the bearing capacity and avoid the bearing heating phenomenon.
★The bearing inner sleeve design method avoids the bearing being directly installed on the shaft, and the mating radial thrust ball bearing can be easily disassembled during maintenance.
★The design of the large oil tank ensures that the heat generated by the bearing is diffused in time.
★The oil slinger design ensures good lubrication of the bearings.
★The heat sink outside the bearing chamber increases the heat dissipation effect.
★Cooling pipes can be installed in the oil tank to directly cool the lubricating oil in the bearing chamber, which is different from the traditional cooling method of the bearing.
★The bearing parts are designed separately to avoid the influence of the sealing shaft sleeve on the bearing, which is convenient for installation and maintenance.
(II) sealing parts
★The sealing parts of the driving end and the non-driving end are all assembled sealing parts.
★Collectible seal components can be configured as single-face and "tandem" double-face mechanical seals.
★Some working conditions can also be configured with packing system.
★Various forms of sealing members may provide a cavity cooling system.

3. Scope of application
The product can transport a variety of clean or lightly contaminated flammable, explosive, neutral, strong corrosive media. Mainly used in cooling and heating systems, boiler feed water, condensate water, descaling and general industrial applications. Such as industrial water supply devices, thermal power plants, oil refineries, petrochemical industry, urban water supply devices, 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
