Product Main feature:
W,WY series horizontal reciprocating vacuum pumps Characteristics:
W type vacuum pump adopts the circle-shaped stationary valve, and its ultimate pressure (absolute pressure) is lower than 2600Pa. The WY type vacuum pumps adopt stripe-shaped moving valves,and its ultimate pressure is lower than 1300Pa.
The pumps are principally used in the chemical industry,pharmaceutical,light industry,building material and electrical appliance etc.
Mechanical transmission part:
The mechanical transmission part of the entire mechanism is in a closed body, and the vacuum pump crankshaft is supported in tapered roller bearings on both sides of the body. A large pulley is mounted on one end of the crankshaft to drive the transmission portion. The connecting rod connects the journal of the crankshaft with the crosshead. A large pulley is mounted at one end of the piston rod to drive the transmission portion. The other end is mounted on the tapered bore of the piston and secured by a nut. The motor and the small pulley mounted on the shaft drive the crankshaft to rotate by the triangular tape, so that the piston reciprocates in the cylinder through the action of the connecting rod and the crosshead.
When the connecting rod crank mechanism moves in the machine body, the lubricating oil in the oil pool is splashed to lubricate the friction surface of the bearing, crankshaft neck, crosshead and slip. In order to facilitate the inspection and maintenance of the transmission mechanism, the door is provided with a detachable door cover on both sides and the back, and an oil window is arranged on the rear cover to indicate the oil level of the oil pool in the body.
Gas circulation part:
The air chamber and the cylinder are integrally formed, the air inlet chamber is provided with an intake valve as an air inlet, and the air chamber is provided with an exhaust valve as an exhaust port, and a valve plate and a coil spring are formed on the air groove of the valve to form a check valve. To control the intake and exhaust and automate the gas distribution.
There is a piston in the cylinder, and the piston is equipped with a piston ring to ensure that the ends of the cylinder separated by the piston are airtight. When the piston reciprocates in the cylinder, the volume at both ends of the cylinder is constantly changed, the area of one end enlarges the suction gas, and the other end reduces the exhaust gas. The combined action of the piston and the air valve periodically completes the suction and exhaust of the vacuum pump.
The cooling water flowing in the water jacket of the cylinder takes the heat generated by the compressed surface of the gas and the heat generated by the friction of the metal surface, so that the cylinder does not overheat. The cooling water flows into the water from below the cylinder head, and flows out of the vacuum pump through the water outlet of the water jacket.
The friction surface between the inner wall of the cylinder and the piston ring is lubricated by the oil cup mounted on the cylinder.
W series reciprocating vacuum pumps use:
W series pump (a.k.a Piston vacuum pump) is one of the main equipment gaining rough vacuum, used for evacuating air in a sealed vessel. It widely used in the chemical and food industries, and is particularly suitable for pumping gases in the vacuum distilling, vaporizing, dipping, concentrating, crystal, drying and filtering.

FAQ
Q: What's your MOQ?
A: One set;
Q: What are the causes of no flow or insufficient flow of centrifugal pump?
A: There is air in the suction pipe or pump, which needs to be discharged. Air leakage is found in the suction pipeline, and the leakage is repaired. If the valve of suction line or discharge line is closed, relevant valve shall be opened. If the suction height is too high, recalculate the installation height. The suction line is too small or blocked.
Q: How to resist cavitation in centrifugal pump?
A: Improve the structure design from the suction to the impeller of the centrifugal pump;Adopt double stage suction impeller and use anti-cavitation material;
Q:What is the function of rubber ball in water ring vacuum pump?
A: Rubber ball in water ring vacuum pump, the correct name is called rubber ball valve. Its role is to eliminate the pump equipment in the operation process of the phenomenon of over compression or insufficient compression.
Q:How long is warranty?
A:One year formain construction warranty.
Q:How can I pay for my items? What is the payment you can provide
A:Usually by T/T, 30%-50% deposit payment once PI/Contract confirmed, then the remaining balance will be paid after inspection and before shipment via T/T or L/C;
