CP53 CIRCULATING PUMP MANUAL PLUS

For safety of operation, so that mercury from C does not enter the valve chambers, the minimum pressure encountered in millimeters of mercury plus the height of the top of C above the rest level of the mercury in the small-borc tubing should be equal to or greater than atmospheric pressure.įor operating a t pressures down to a few millimeters the upper contact on D must be below the bottom of C by a t least the lowest pressure of the operating pump plus the resistance of one check valve. The operating range of pressures for any set of fixed dimensions or level of bulb D is the difference between the maximum and minimum operating pressures and is equal to atmospheric pres- sure minus the sum of the distance between the top and bottom of C, the distance between the top and bottom contacts on D, the lowest pressure of the operating pump, and twice the resistance of one check valve. The maximum operating pressure is equal to or less than the atmospheric pressure, minus the resistance of one check valve, minus the height of the top of C above the lower contact on D. The minimum operating pressure in millimeters of mercury is equal to or greater than the height of the bottom of C above the upper contact on 8, plus the resistance of one check valve, and the lowest pressure reached by the operating vacuum pump. The height between the bot- tom of this small-bore tubing and the top of C should exceed the mercury equivalent of one atmosphere pressure for safe opera- tion a t pressures down to a few millimeters. This is accomplished by construct- ing the right arm of the U-tube of small-bore tubing pressure variations register on this arm while the maximum height in C' remains practically unchanged. The pump was designed to operate with a continually varying pressure inside the system. Residual gas in the pump can be let out,into the system by drawing the mercury down into the reservoirs.

If other check valves were used this minimum might be reduced. This is the pressure required to overcome the resistance of the mercury check valves. The pump can be made to operate a t pressures as loiv as 3 to 4 mm. The levels of the mercury in A and B are adjusted by means of the reservoirs below them. This period could be varied by changes in the dimensions of the various parts of the apparatus. The pump used by the authors made a complete cycle once a minute a t 200-mm. Gas is forced out through B while A acts as the check valve. When the mercury has been lowered sufficiently so that C is empty, the cycle is reversed by letting air into D and allowing the mercury to flow back into C. Gas is drawn in through valve A by lowering the mercury in C, thus reducing the pressure inside the pump below that of the system the lowering of the mercury is accomplished by applying a vacuum on bulb D. The pump consists of two small one-way valves and two 50-cc.

One morning last week the central heating pump jammed and I had to free it off using the restart. This is used when filling, venting or draining the system. When the manual lever is moved to the right, the valve is open. I need a new pump or can I manually restart it? I have a Myson Compact CP5 I have hot water but no heat to any radiator, what is the problem. Fig Manual Restart Knob and Speed Regulator Knob Location.
